The method of attachment between a rubber resourceswith

 

(57) Abstract:

The invention relates to a method for mounting between a rubber-based neovolcanic rubbers: General purpose unsaturated and saturated. One of the rubbers on the basis of unsaturated rubbers General naznacheniya pre vulcanized, roughness, put glue and dry it. Then it is connected with a second unvulcanized rubber on the basis of a saturated rubber and vulcanized them together. Pre-vulcanization of rubber-based unsaturated rubbers aligns the degree of unsaturation of the joined rubber. The proposed method can be used for fastening the heel of the valve of the rubbers on the basis of unsaturated rubbers General purpose to the camera body based on butyl rubber. 1 C. p. F.-ly, 5 PL.

The invention relates to the field of rubber processing machine, in particular to a method for mounting between a rubber-based resourceservice rubbers: General purpose unsaturated and saturated rubber.

In the modern production of the known methods of fastening together two neovolcanic rubbers on the basis of unsaturated rubbers of General purpose and saturated rubber, distinguished p is to aviatica with both rubbers [1]; by gluing two pre devulcanizing rubbers [2] and by modifying the halogenation of saturated butyl rubber with subsequent covulcanization [3].

However, these known solutions, each individually, may not solve the problem quick and secure attachment to each other resourceswith rubbers.

Next to be described is the method of attachment between resourceswith rubbers, which are connected with rubber-based neovolcanic between an unsaturated rubber and a thick rubber, with one of the rubbers pre vulcanized, and then combine it with the second unvulcanized rubber and vulcanized them together [4].

The technical result of the invention is to provide a durable connection resourceswith rubbers with minimal effort and time.

To achieve the technical result in the attachment method between resourceswith rubbers, which are connected with rubber-based neovolcanic between an unsaturated rubber and a thick rubber, with one of the rubbers pre vulcanized, and then combine it with the second unvulcanized the different rubber General purpose, the roughness of it, put glue, dry it and combine it with unvulcanized rubber-based unsaturated rubber for subsequent joint vulcanization.

The use of unvulcanized rubber on the basis of a saturated rubber in the proposed method allows to increase the number of break ties between the film adhesive and butylcatechol. At the same time the adhesive on the basis of well-bromobutyl rubber devulcanized with saturated rubber, and rubber materials based on unsaturated rubbers for General use.

Example 1 (comparative). Mount two rubbers, neovolcanic among themselves on the basis of unsaturated rubbers General purpose table. 1) and on the basis of a saturated rubber (PL. 2) was made by combining raw rubber, with advanced refreshment surfaces of both rubbers gasoline and further vulcanization. The strength characteristics of the two mounting rubbers are shown in table. 5.

Example 2 (comparative). Mount two neovolcanic rubber was carried out using the third rubber compound capable of covulcanization as with the first and second rubber mixture. The third part of the rubber mixtures is given in table. 3. Kriplani gasoline, the surface of the third rubber was refreshed on both sides. All three of rubber connected to each other and subjected to vulcanization. The thickness of the third rubber-primers was 0.5 mm, the Strength characteristics of the compounds obtained resins are shown in table. 5.

Example 3. Mount two neovolcanic rubber was carried out analogously to example 1, in addition to the surface of the joined rubber was applied based adhesive bromatologia rubber adhesive composition is given in table. 4 (composition of the polymer part adhesive similar to rubber mixtures based on bromatologia rubber). The strength characteristics are presented in table. 5.

Example 4 (comparative). Mount two neovolcanic rubber was carried out after pre-vulcanization (curing mode is specified in the table. 5), as follows covulcanization rubber pre serahuli, refreshing, gasoline, connected by the use of third rubber-primer thickness of 0.5 mm and then subjected to vulcanization in the same mode. Strength properties are given in table. 5.

Example 5 (prototype). Mount two neovolcanic rubber was carried out analogously to example 4, however, instead of rubber-primer is of two neovolcanic rubber was carried out in the following way: rubber-based unsaturated rubbers (PL. 1) was previously vulcanizable and serahuli, and rubber-based saturated rubber (PL. 2) did not vulcanizable. The surface of the joined rubber refreshed gasoline, put glue (PL. 4), connected them together and subjected to vulcanization in the same mode of cure.

Example 7 (comparative). Mount two neovolcanic rubber was carried out analogously to example 7, however, pre-vulcanization were subjected to rubber-based saturated rubber, and rubber-based unsaturated rubbers were not vulcanizable.

The strength characteristics of the rubber compounds according to example 7 are shown in table. 5.
