Background
The floor is a common home decoration material, and can play a series of roles of beauty, heat preservation, heat insulation and the like in home decoration. Due to the special use environment, the floor needs to have good moisture-proof and heat-insulating properties. The foam layer of the floor in the market at present generally adopts polyurethane foam or polyvinyl chloride foam, and although the polyurethane foam has good heat insulation performance, the moisture-proof effect is poor because the internal cell structure of the polyurethane foam is a through hole. Polyvinyl chloride foam has the advantage of higher strength, but poorer thermal and moisture insulation properties.
For example, a patent published by 2015.08.26 with publication No. CN103865208B entitled "PVC composite material" discloses a PVC composite material, which comprises, by weight, 3-5 parts of PVC 40-60 parts, 40-60 parts of light calcium carbonate, 0.8-1.2 parts of an inorganic/organic composite foaming agent, 3-5 parts of a foaming regulator, 2-4 parts of a toughening agent, 0.8-1.2 parts of a lubricant and 1.5-2.5 parts of a stabilizer, wherein the weight ratio of the inorganic foaming agent to the organic foaming agent in the inorganic/organic composite foaming agent is 1/2-1. The invention also discloses a foaming plate made of the PVC composite material, and a matched production method, equipment and floor, so that the prepared PVC product has high structural strength, good foaming performance and satisfactory silencing effect; although the strength is high, the heat preservation and moisture resistance are poor.
Therefore, a new type of moisture-proof and heat-insulating floor material is yet to be developed.
