Abstract

The invention relates to a modified PVC (polyvinyl chloride) foaming building material product, and belongs to the technical field of a building material. The modified PVC foaming building material product consists of polyvinyl chloride, light calcium carbonate, heavy calcium carbonate, additive and a modifying agent, wherein the mass ratio of the polyvinyl chloride to the light calcium carbonate to the heavy calcium carbonate to the additive to the modifying agent is (95 to 110) to (20 to 30) to (20 to 30) to (15 to 20) to (0.4 to 0.8). The additive consists of a stabilizer, glycerin monostearate, titanium oxide, color powder, a lubricating agent, a foaming agent, a foaming adjusting agent and a catalyst, and the modifying agent consists of PE wax and an ultraviolet absorption agent. After the ultraviolet absorption agent 531 is added, the novel modified PVC foaming building material product is good in aging resistance and good in hardness; the foaming rate is higher than that of products of the same kind, thus the mass per meter is light, and the convenience in installation and transportation is realized. Meanwhile, the PE wax is added into the formula, so that appearance precision and brightness of the product are improved.

Description

technical field [0001] The invention relates to a modified PVC foamed building material product and a processing method thereof, belonging to the technical field of building materials. Background technique [0002] PVC is one of the earliest synthetic resins used in industry, and it is also one of the three largest plastics in the world. Due to its excellent electrical insulation performance, it can be used in electrical, electronic, aviation and other fields. It can be made into raincoats, plugs, switches, artificial leather, etc. However, in most applications, PVC is used as outdoor appliances. It is prone to aging, yellowing, and deterioration of physical and chemical properties due to wind and sun, which will cause serious damage to the use. inconvenient. [0003] Based on this, this application is made. Contents of the invention [0004] In order to overcome the above-mentioned defects in the existing PVC foam building materials, the invention provides a modified P...
