Specific surface area by BET method determined in the same manner as described above for the hydrate of aluminum oxide.

Polyvinyl alcohol

Example polyvinyl alcohol is an ordinary polyvinyl alcohol, which is produced by hydrolysis of polyvinyl acetate. Polyvinyl alcohol may have srednekvadraticheskogo degree of polymerization of $ 2000 or more and 4500 or less, and even 3000 or more and 4,000 or less. Srednekvadraticheskaya degree of polymerization, a component of 2000 or more and 4500 or less, leads to improved ability to absorb the dye, the optical density and resistance to cracking when bent and suppresses the occurrence of cracking during application. Polyvinyl alcohol can be a partially or completely saponified polyvinyl alcohol. Polyvinyl alcohol may have a degree of saponification, comprising 85 mol.% or more and 100 mol.% or less. Example polyvinyl is the first alcohol is a PVA 235 (manufacturer Kuraray Co., Ltd., the degree of saponification of 88 mol.%, the average degree of polymerization of 3500).

In the case where polyvinyl alcohol is included in the liquid coating for kratkovremennogo layer, polyvinyl alcohol may be contained in the aqueous solution. Containing polyvinyl alcohol aqueous solution may have a concentration of polyvinyl alcohol, which is 4.0% of the mass. or more and 15.0% of the mass. or less in terms of solid content. The concentration of polyvinyl alcohol 4.0% of the mass. or more and 15.0% of the mass. or less, leads to the suppression of a significant reduction in drying rate due to excessive reduction of the concentration of the liquid coating, and also leads to the suppression of the reduction of smoothness due to the significant increase in the viscosity of the liquid coating, which is caused by the increase in the concentration of the liquid coating.

Each of krasnopresnya optional layers may also contain other binder material, in addition to polyvinyl alcohol. In order to sufficiently ensure the beneficial effects of the aspects of the present invention, the content of the binder material, in addition to polyvinyl alcohol, may be 50,0% of the mass. or less relative to the total weight of polyvinyl alcohol.

The ratio between the first kratkovremennym layer and the second kratkovremennym layer will be described below.

The ratio between the first kratkovremennym layer and the second kratkovremennym layer

Traditional raskopanny layer containing a crosslinking agent such as boric acid, in addition to the inorganic particles and polyvinyl alcohol, contains a relatively large amount of cross-linking agent. Thus, such raskopanny layer often has a high degree of crosslinking. In this case, the cracking that occurs during coating or drying (after coating), be effective inhibition, resulting in raskopanny layer with satisfactory capacity to absorb the paint. One is to result raskopanny layer is so hard and brittle due to their high degree of cross-linking what, in particular, raskopanny layer sometimes has a low resistance to cracking when bent.

In the case where no cross-linking agent is not contained, the cracking that occurs after coating, definitely reduces the ability to absorb the paint. In addition, resistance to cracking when bent, which is considered high, because no crosslinking agent is not contained, it is sometimes low. The reason for this is unclear but it is likely that in the case where no molecules of polyvinyl alcohol are not sewn, weaken the adhesion forces between polyvinyl alcohol, inorganic particles and water-resistant backing.

The authors of the present invention have conducted intensive studies and found the following: resistance to cracking when bent krasnopresnya ply the water-resistant adhesion between the substrate and the first kratkovremennym layer or between the first kratkovremennym layer and the second kratkovremennym layer. Resistance to cracking when bent krasnopresnya layers also affects the flexibility krasnopresnya layers. When polyvinyl alcohol in the first krasoprema layer and the second krasoprema layer adjacent to water-resistant backing, sew to a certain extent, provided a satisfactory resistance to cracking when bent. is there an optimal interval of the degree of crosslinking of polyvinyl alcohol from the viewpoint of achieving good resistance to cracking when bent. However, in this interval there is cracking after coating, and in some cases decreases the ability to absorb the paint. Accordingly, the authors of the present invention have found that the degree of crosslinking of each of the two krasnopresnya layers is determined to increase resistance to cracking after coating, the ability to absorb paint and resistance to cracking when bent. This discovery led to the creation of aspects of the present invention.

In aspects of the present invention, the mass ratio of the content of boric acid and the content of polyvinyl alcohol in the first krasoprema layer is 2.0% of the mass. or more and 7.0% of the mass. or less. The content of boric acid of 2.0% of the mass. or more and 7.0% of the mass. or less, resulting in a satisfactory contact between the waterproof substrate and the first kratkovremennym layer, resulting in suppression of occurrence of cracking after coating and increases resistance to cracking when bent. The mass ratio of the content of boric acid and the content of polyvinyl alcohol in the first krasoprema layer may amount to 3.0% of the mass. or more and 6.5% of the mass. or less.

First raskopanny layer contains inorganic particles comprising at least one compound selected from aluminum oxide,hydrate of aluminum oxide and finely dispersed silicon dioxide. The hydrate of aluminum oxide has a high surface density of hydroxyl groups and a high bonding strength with polyvinyl alcohol as compared with high disperse silicon dioxide and aluminum oxide. First raskopanny layer may have a content of hydrate of alumina, amounting to 50.0% of the mass. or more, including 80% of the mass. or more and even 100 wt. -%, i.e., the inorganic particles contain only the hydrate of aluminum oxide, relative to the total weight of the inorganic particles from the point of view of resistance to cracking when bent.

The mass ratio of the content of polyvinyl alcohol and the content of inorganic particles in the first krasoprema layer may be 11,0% of the mass. or more and 40.0% of mass. or less, and even to 12.0% of the mass. or more and 30.0 per cent of the mass. or less. The content of polyvinyl alcohol, average of 11.0% of the mass. or more and 40.0% of mass. or less, leads to increased suppression of cracking after application, and also leads to improved ability to absorb paint and resistance to cracking when bent.

The mass ratio of the content of boric acid and the content of polyvinyl alcohol in the second krasoprema layer is higher than in the first krasoprema layer. The mass ratio of the content of boric acid and the content of polyvinyl alcohol in the second croscope mnom layer not simply increases, but is 10.0% of the mass. or more and 30.0 per cent of the mass. or less. When the content of boric acid is in the above range, the second raskopanny layer has a sufficiently high degree of crosslinking polyvinyl alcohol compared with the first kratkovremennym layer. Thus, even if the drops of paint into the surface, polyvinyl alcohol is less prone to swelling, resulting in a very high ability to absorb the paint and improved resistance to cracking during coating and drying. The mass ratio of the content of boric acid and the content of polyvinyl alcohol in the second krasoprema layer may be 12,0% of the mass. or more and 25.0% of the mass. or less.

The mass ratio of the content of polyvinyl alcohol and the content of inorganic particles in the second krasoprema layer may be 12,0% of the mass. or more and 20.0% by mass. or less, and even 13,0% of the mass. or more and 18.0% of the mass. or less. The content of polyvinyl alcohol, amounting to 12.0% of the mass. or more and 20.0% by mass. or less, leads to increased suppression of cracking after application, and also leads to improved ability to absorb paint and resistance to cracking when bent in combination with the structure of the first kratkovremennogo layer. Second raskopanny layer contains highly dispersed silicon dioxide is as inorganic particles. Second raskopanny layer may have a content of highly dispersed silicon dioxide, forming 90% of the mass. or more and even 100% of the mass. with respect to the total weight of inorganic particles.

The thickness of the second kratkovremennogo layer may be 5.0 μm or more and 20.0 μm or less, and even to 7.0 μm or more and 15.0 μm or less. The thickness of the first kratkovremennogo layer may be of 20.0 μm or more and 40.0 μm or less, and even of 20.0 μm or more and 28.0 μm or less. The ratio of the thickness of the second kratkovremennogo layer and the first raskopanny layer, i.e., the ratio of the second raskopanny layer/first raskopanny layer may be of 0.08 or more and 1.0 or less. The ratio of the thickness average of 0.08 or more and 1.0 or less, resulting in a satisfactory resistance to cracking when bent, the ability to absorb paint and resistance to cracking during coating and drying.

Although cracovienne layers according to aspects of the present invention are two layers, a thin film can be applied over the second kratkovremennogo layer, between the second kratkovremennym layer and the first kratkovremennym layer or between the first kratkovremennym layer and the substrate, with the proviso that it will not significantly diminish the effects of aspects of the present invention.
