Abstract

The invention discloses a foaming material with modifying filler. The foaming material is characterized by being prepared from the following raw materials in parts by weight: 80-90 parts of linear low density polyethylene, 12-16 parts of SG-5 polyvinyl chloride, 20-24 parts of calcium carbonate powder, 2-3 parts of stearic acid, 2-3 parts of zinc oxide, 4-5 parts of azodicarbonamide, 5-7 parts of chlorinated paraffin, 3-5 parts of polyethylene terephathalate, 4-6 parts of titanium dioxide powder, 2-3 parts of triphenyl phosphite and 6-8 parts of modifying filler. Due to addition of the modifying filler, the foaming material has excellent flame retardant effect, and is further endowed with excellent mechanical property, good rebound resilience and strong sound insulation performance. The polyvinyl chloride foaming material simultaneously has the characteristics of heat insulation, light weight, low water absorption and the like. The foaming material also has the advantages that the operation is simple, the raw materials are easily available, and the cost is low.

Description

technical field [0001] The invention relates to a foaming material, in particular to a foaming material added with a modified filler. Background technique [0002] The foamed board made of polyvinyl chloride is mainly used in the manufacture of advertising cabinets and bathroom cabinets. It was the first to introduce equipment and technology from Europe, and the quoted product standards also refer to European standards. The density of the board is relatively high. In recent years, with the development of domestic equipment, especially the development of additives, the density of the board has been greatly reduced, which can reach 0.4~0.45g / cm3, thus greatly improving the application space of the board and reducing the cost of use , but how to further reduce the density of the board and still achieve better performance is a bottleneck in the research of lightweight boards. Flame-retardant foaming materials are widely used in various occasions that require fire protection bec...
