Abstract

The invention relates to a polyethylene foam material prepared by utilizing a recycled foam material. The polyethylene foam material sequentially comprises the following components in parts by weight: cross-linked polyethylene foam material waste, composite filling agent, compound cross-linking agent, compound foaming agent and foaming auxiliary agent and is sequentially processed and produced through the cross-linked polyethylene foam material waste, the composite filling agent, the compound cross-linking agent, the compound foaming agent and the foaming auxiliary agent. The polyethylene foam material with excellent property disclosed by the invention is produced by sequentially carrying out cross-linked polyethylene foam material waste processing, raw material mixing, raw material retreatment, slice cutting, compression moulding and cooling shaping on the cross-linked polyethylene foam material waste, the composite filling agent, the compound cross-linking agent, the compound foaming agent and the foaming auxiliary agent which are in certain parts by weight, thereby reducing the production cost, protecting the environment and recycling the resources.

Description

technical field [0001] The invention relates to a polyethylene foam material prepared by foaming recycled materials and a production method thereof. Background technique [0002] The chemical foaming technology generally uses mixing equipment to mix and disperse the chemical foaming agent, crosslinking agent and filler in the polymer resin matrix at low temperature to form a foaming blank, and then put the foaming blank into the mold installed on the hydraulic press to heat up the mold. The heat simultaneously triggers the crosslinking of the polymer resin and the decomposition of the blowing agent, and the existence of the clamping force promotes the dissolution of the gas generated by the decomposition of the blowing agent into the polymer matrix to avoid its early nucleation. Finally, the pressure is relieved by opening the mold instantaneously, causing the nucleation and growth of cells to form a foamed material. Compared with other foaming technologies such as extrusi...
