Antibacterial and mildew-proof PP foam board and preparation method thereof

Abstract

The invention discloses an antibacterial and mildew-proof PP foam board and a preparation method thereof. The antibacterial and mildew-proof PP foam board is prepared by, by weight, 72-94 parts of polypropylene, 41-63 parts of chlorothalonil, 24-46 parts of cyanoethyl cellulose, 3-6 parts of dichlorophenyl dimethyl urea, 13-19 parts of tricresyl phosphate, 17-23 parts of magnetic wave stone, 10-15 parts of glass fibers, 4-8 parts of oxidized polyethlene wax, 2-3 parts of zinc isooctanoate, 15-20 parts of opal shale, 34-48 parts of waste bauxite cement, 1-2 parts of magnesium isooctanoate, 1.5-2.5 parts of diethyl azodicarboxylate, 26-39 parts of alum dregs, 2-4 parts of oxine-copper, 12-18 parts of tributyl citrate and 4-7 parts of ammonium carbonate. The antibacterial and mildew-proof PP foam board has the advantages that the chlorothalonil and the cyanoethyl cellulose are used to modify the polypropylene, the dichlorophenyl dimethyl urea, the tricresyl phosphate, the oxine-copper, the magnetic wave stone, the opal shale and the glass fibers are added for compositing, the antibacterial and mildew-proof performance of the foam board can be increased, and the water resistance and weather resistance of the foam board can also be increased.

Description

technical field [0001] The invention relates to a PP foam board and a preparation method thereof, in particular to an antibacterial and mildew-proof PP foam board and a preparation method thereof. Background technique [0002] PP foam board, also known as polypropylene foam board, its chemical composition is polypropylene (Polypropylene). PP foam board has excellent processability due to its excellent thermal stability and dimensional stability of products under high temperature, suitable and soft surface, excellent microwave adaptability and degradability. It can be adjusted according to the product performance and use, and can be widely used in auto parts, equipment manufacturing, stationery, packaging, building materials and other fields. [0003] In recent years, PP foam boards have developed rapidly, and a wide variety of PP foam boards with different properties have appeared on the market. However, compared with the performance of foreign PP foam boards, there is s...

AI Technical Summary

Problems solved by technology

However, compared with the performance of foreign PP foam boards, there is still a big gap between the antibacterial and mildew-proof properties of domestically produced PP foam boards.

[0004] Liu Qiongqiong, Cao Jing and others used the method of melt blending to fill mullite powder in polypropylene in their article "Preparation and Properties of Mullite / PP Composite Materials", which played a certain role in strengthening. The crystallization temperature and thermal stability of the composite material are improved, but the thermal insulation performance and sound insulation and sound absorption performance of the polypropylene composite material are not significantly improved.
