Abstract

The invention discloses a formula of foamed polyethylene plastic. The foamed polyethylene plastic comprises polyethylene plastic and additives, wherein the additives comprise fatty alcohol-polyoxyethylene ether sodium sulfate serving as a foaming agent, liquid polysulfide rubber serving as a softening agent, acrylate copolymer serving as a toughening agent, dicyclohexyl phthalate serving as a plasticizer, benzoyl peroxide serving as a cross-linking agent and vinyltriethoxysilane serving as a coupling agent. After the foaming agent and various auxiliary aids are added into the polyethylene plastic, the mechanical properties such as softness, toughness, tear resistance and plasticity of the foamed polyethylene plastic are greatly improved, and the service life of the foamed polyethylene plastic is prolonged; and the reaction rate of polyethylene in the production process can be improved, so that production cost is greatly reduced.

Description

technical field [0001] The invention relates to a plastic formula, in particular to a foamed polyethylene plastic formula. Background technique [0002] With the rapid development of my country's national economic construction, a large number of high-sensitivity, high-precision electronic equipment, optical instruments, instrumentation appliances and other equipment and devices require high-quality packaging with good protection performance. At the same time, the fields of railway, navigation, aviation packaging and transportation that are matched with the transportation of the above products are also in great need of protective materials with excellent performance. The research on foamed polyethylene that has emerged in our country this year is just the beginning of solving this problem, and results have been obtained a few days ago. [0003] Since the foamed polyethylene resin is a foam, it is excellent in heat insulation and heat retention, and also excellent in cushioni...
