Styrene-butadiene-rubber ultraviolet-resistant PE (Polyethylene) foaming board material and preparation method thereof

Abstract

The invention discloses a styrene-butadiene-rubber ultraviolet-resistant PE (Polyethylene) foaming board material and a preparation method thereof. The styrene-butadiene-rubber ultraviolet-resistant PE foaming board material is prepared from the following raw materials in parts by weight: 67-78 parts of low-density polyethylene, 35-48 parts of acrylate rubber, 28-40 parts of chlorinated polyethylene, 13-21 parts of dimethoxyethyl phthalate, 2-4 parts of di(tert-butylperoxyisopropyl) benzene, 1-3 parts of triallyl isocyanurate, 1-3 parts of bis-ethylhexyloxyphenol methoxyphenyl triazine, 4-8 parts of silicon dioxide, 16-24 parts of loofah sponge, 2-5 parts of laterite, 10-15 parts of paraffin oil, 4-7 parts of glycerinum, 32-44 parts of bamboo residue, 5-10 parts of nano titanium dioxide, 17-24 parts of nano kaolinite, 36-49 parts of styrene butadiene rubber, 4-8 parts of zinc p-toluenesulphinate, 5-10 parts of perlite, 5-8 parts of homosalate and 3-5 parts of magnesium methacrylate. The styrene-butadiene-rubber ultraviolet-resistant PE foaming board material disclosed by the invention has the advantages of good ultraviolet resistance, light stability, weathering resistance and ageing resistance.

Description

technical field [0001] The invention relates to a PE foam board and a preparation method thereof, in particular to a styrene-butadiene rubber anti-ultraviolet PE foam board and a preparation method thereof. Background technique [0002] Polymer foam board is a polymer material with plastic or rubber as the basic component and contains a large number of bubbles. It has many excellent properties, such as light weight, heat insulation, sound absorption, high specific strength, etc., so it has been widely used in industry, agriculture, construction, transportation and other fields. Since the advent of polymer foamed boards, their uses have become more and more extensive, and their varieties have been continuously enriched. Among them, PE foamed boards are a relatively common polymer foamed board. Good, stable chemical properties, not susceptible to corrosion, good processing performance, easy to shape; cheaper price. [0003] In recent years, as the country vigorously develo...

Problems solved by technology

However, compared with the performance of foreign PE foam boards, there is still a big gap between the light stability and UV resistance of domestically produced PE foam boards.

[0004] Zeng Anran, Li Yunlong and others used emulsion polymerization to prepare styrene-grafted cellulose whiskers in their article "Study on the Properties of Styrene-Grafted Cellulose Whiskers Reinforced LDPE Composite Materials" and used them to reinforce low-density polyethylene. Ethylene (LDPE), which improves the Rasher strength, crystallization temperature and thermal stability of the composite material, but does not significantly improve the thermal insulation performance and sound absorption and sound insulation performance of the composite material
