Fireproof expanded polyethylene material and preparation method thereof

Abstract

The invention relates to the field of expanded polyethylene, and provides a fireproof expanded polyethylene material. The fireproof expanded polyethylene material aims at solving the problem that theshock absorption and shock resistance of the expanded polyethylene material are easily influenced by adding a flame retardant agent into the expanded polyethylene material, and comprises, by weight, the following components: 30-45 parts of high pressure polyethylene, 10-15 parts of ethylene-vinyl acetate copolymer, 5-10 parts of antimony trioxide, 15-25 parts of decabromodiphenyl ethane, 30-45 parts of aluminum hydroxide, 10-18 parts of azodicarbonamide, 0.2-0.8 part of a crosslinking agent DCP, 0.4-1 part of zinc oxide and 0.1-0.5 part of stearic acid. The invention discloses a preparation method of the fireproof expanded polyethylene material. The method comprises the following steps of: S1, banburying; S2, carrying out open milling; S3, carrying out primary foaming; and S4, carrying outsecondary foaming. Antimony trioxide, decabromodiphenylethane and aluminum hydroxide are mixed according to a certain proportion and are added into the expanded polyethylene as flame retardant agentsto prepare the fireproof expanded polyethylene material, so that the fire resistance of the fireproof expanded polyethylene material is improved, and meanwhile the fireproof expanded polyethylene material has good shock absorption and shock resistance.

Description

technical field [0001] The invention relates to the field of foamed polyethylene, more specifically, it relates to a fireproof foamed polyethylene material and a preparation method thereof. Background technique [0002] Foamed polyethylene is a new type of environmentally friendly packaging material with high-strength cushioning, shock-absorbing and shock-resistant capabilities. Foamed polyethylene is flexible, light and elastic, and has a series of properties such as heat preservation, moisture resistance, friction resistance, and corrosion resistance. It has been widely used in the packaging of electronics, electrical appliances, precision instruments, and high-end furniture. [0003] In order to improve the flame retardancy of foamed polyethylene, flame retardants are usually added to foamed polyethylene, but after adding flame retardants to foamed polyethylene, the cell uniformity of foamed polyethylene is usually affected As a result, the elasticity of the foamed polye...

Problems solved by technology

[0003] In order to improve the flame retardancy of foamed polyethylene, flame retardants are usually added to foamed polyethylene, but after adding flame retardants to foamed polyethylene, the cell uniformity of foamed polyethylene is usually affected Therefore, the elasticity of foamed polyethylene is easily affected, which in turn easily affects the shock absorption and shock resistance of foamed polyethylene. Therefore, there is still room for improvement
