Abstract

The invention discloses a damp-proof heat preservation layer material for a floor. The material is prepared from the following raw materials in parts by weight: 70 to 85 parts of an ethylene-vinyl acetate copolymer, 14 to 19 parts of methyl vinyl phenyl silicone rubber, 18 to 23 parts of an elastomer, 6 to 9 parts of a dimethyl siloxane-ethylene oxide copolymer, 4 to 7 parts of expanded perlite powder, 2 to 4 parts of aluminum silicate fibers, 1.7 to 2.4 parts of a foaming agent, 0.6 to 0.8 part of an auxiliary foaming agent and 4 to 6 parts of other auxiliary agents. The damp-proof heat preservation layer material for the floor is an EVA foaming material, has a low heat conductivity coefficient and is good in heat preservation effect, low in water absorption rate, good in damp-proof effect, light in weight, high in elasticity, small in permanent compression deformation, and durable in use.

Description

technical field [0001] The invention relates to the field of foam materials, in particular to a floor moisture-proof and heat-insulating layer material and a preparation method thereof. Background technique [0002] Flooring is a common home decoration material, which can play a series of functions such as beauty, heat preservation and heat insulation in home decoration. Due to its special use environment, the floor needs to have good moisture-proof and thermal insulation properties. At present, the foam layer of the floor on the market generally adopts polyurethane foam or polyvinyl chloride foam. Although polyurethane foam has good thermal insulation performance, because its internal cell structure is a through hole, its moisture-proof effect is relatively poor. The advantage of polyvinyl chloride foam is its high strength, but its thermal insulation and moisture resistance are poor. [0003] For example, a patent with the publication number CN103865208B in the 2015.08.2...
