The invention is used in construction as a slab of insulating material. Plate material made by the method of the flat extrusion of the filler particles mixed with a binder, at a temperature of 18-20°and a pressure of 3 MPa. To reduce the viscosity of epoxy resin ED-20 is heated to 50-60°With, then it enter the curing agent and plasticizer. The obtained binder are thoroughly mixed and added to it a mixture of pine sawdust and polystyrene chips. The cooked mass is placed in a metal mold and pressed into the day. Then, to accelerate curing of the composition to produce a heat treatment at a temperature of 80°C for 2 hours. Scheme for epoxy-wood composition shown in the drawing. For similar taken polystyrene plates manufactured bespressovyj way of suspension foaming polystyrene with or without the addition of flame retardant additives, intended for thermal insulation as a middle layer enclosing constructions and industrial equipment (GOST 15588-86. The polystyrene plates. Technical conditions. - M.: Publishing house of standards, 1986. - 12 S.). This material has a low mechanical strength and durability. For the prototype was made of epoxy-woody composition for pok is itia wood (for surfacing) (patent RU 2028344, C1, 09.02.1995). The composition in parts by weight: 10-20 epoxy Dianova resin ED-20, 10-20 dibutyl phthalate as a plasticizer, 10-15 polyethylenepolyamine (PEPA) as the amine hardener, 30-70 graphite and 30-70 talc as a filler. The disadvantage of this material is its high thermal conductivity. Was the goal of the project is to develop environmentally friendly wood composite with the use of waste polystyrene foam used for thermal insulation and high performance properties. This technical problem is achieved in that the binder used epoxy resin grade ED-20 (GOST 10587-84), and as a filler - pine sawdust and polystyrene chips. Curing produced by polyethylenepolyamine (PEPA) (TU 2413-357-00203447-99) at room temperature and atmospheric pressure. Polystyrene powder obtained by crushing waste when replacing the insulation coatings of pipelines, industrial equipment, chillers, heaters, wall panels, covering buildings, defective insulation boards. Particle size of the fillers was determined as the residue on the sieve size, mm%, respectively pine sawdust: 2,5:1,25:0,63:0,315:0,14:0=15:7:34:31:4:9 and for polystyrene crumbs 2,:1,25:0,63:0,315=43:41:12:4. Because EPS crumb has a low weight by volume, the selection ratio of the fillers produced in volume, taking the number of binding 62-66% of the total weight of the composition. Physico-mechanical properties of the compositions shown in table 1 (compositions No. 1-3). When a given quantity of the binder, all the teams have a sufficiently high strength and water resistance, however, when the number of EPS crumbs strength of the composition is reduced. Judging from the mean plane of the fracture, it can be concluded that the adhesive interaction of the particles of the fillers and binders higher than the strength of the polystyrene particles in the gap, which causes a decrease in strength of the composition with the increasing content of EPS. Retained strength, %, after
It should also be noted that with the increasing content of wood filler is an increase in the density and swelling in thickness, and reduced water absorption. Residual strength under transverse bending after 24-hour incubation in the water is high and is 78-83% of the original. To reduce the density of the composition and, consequently, improved thermal properties, a number of compositions with reduced binder content at a fixed ratio fillers (1:1 parts by volume). Fizi what about the mechanical properties of the compositions shown in table 1 (compositions No. 3-7). The table shows that reducing the amount of binding is the decrease in the density, thermal conductivity and mechanical strength, and significantly increase water absorption and swelling. So water absorption increases from 9 to 117% with decreasing binder with 66,1 to 40.9% of the total mass. On this basis the material was obtained with a ratio of polystyrene crumbs and pine sawdust to 2.5:1. parts and binder content of 44.7% of the total mass of the composition (composition No. 8). The resulting material has good insulating properties, sufficient mechanical strength and water resistance. On the basis of the obtained results was selected as the optimum composition ratio polystyrene chips and sawdust to 2.5:1. parts and binder content of 44.7% of the total weight of the composition. Physico-mechanical properties of epoxy-woody composition with polystyrene chips are presented in table 2.
The results show that this composition can be applied as a construction-heat otolaryngo material, moreover, short-term influence of a moist environment without significant reduction in strength properties. thermal conductivity of the proposed composition (0,078 W/m·K) higher than that of polystyrene (0.04 to 0.06 W/m·K), 30-95%, the strength of the above 3 times, and durability in the tens to hundreds of times. So for the entire life of the building (100 years) expanded polystyrene as an additional insulation will need to change more than 10 times, and the proposed composition 1-2 times. Hence the economic impact of the proposed composition is obvious. The authors propose the following structure of epoxy-wood composition, parts by weight: epoxy resin ED-20 - 100; - hardener PEPA - 10; the plasticizer (uterine epoxy ITU-I) - 15; - filler (pine shavings) - 105; - filler (polystyrene chips) - 31. We offer epoxy-wood composition has: - good physical and technical characteristics; - environmental safety; - allows the use of waste products.
