Water-absorbent resin damp-proof PP (Polypropylene) foamed board and preparation method thereof

Abstract

The invention discloses a water-absorbent resin damp-proof PP (Polypropylene) foamed board and a preparation method thereof. The foamed board is prepared from the following raw materials in parts by weight: 92-106 parts of PP, 54-68 parts of PTFE (Poly Tetra Fluoro Ethylene), 4-8 parts of dihydroxy polydimethylsiloxane, 6-9 parts of N-hydroxymethyl stearamide, 20-25 parts of titanium dioxide, 15-20 parts of diisodecyl glutarate, 24-36 parts of a water-absorbent resin, 31-43 parts of quartz tailing powder, 3-6 parts of perfluornonenoxy benzene sulfonate, 26-39 parts of aluminous slag, 4-7 partsof polysiloxane-15, 5-8 parts of lignite wax, 22-34 parts of granite wastes, 3-5 parts of zirconium stearate, 2-3 parts of diazoaminobenzene, 3-4 parts of zinc benzoate and 15-20 parts of dicyclohexyl phthalate. Due to adoption of the dihydroxy polydimethylsiloxane, the perfluornonenoxy benzene sulfonate, the polysiloxane-15, the zirconium stearate, the dicyclohexyl phthalate and the like, the water resistance and the damp resistance of the foamed board are greatly improved, and the PP foamed board disclosed by the invention is good in heat preservation and sound insulation effect, and in addition, is high in water resistance and damp resistance, high in aging resistance, and greatly prior to similar products of other countries.

Description

technical field [0001] The invention relates to a PP foam board and a preparation method thereof, in particular to a water-absorbing resin moisture-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...

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 water and moisture resistance 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.
