Method for preparing wear-resistant lining boards by adopting waste materials of ultra-high molecular weight polyethylene composite material

Abstract

The invention provides a method for preparing wear-resistant lining boards by adopting waste materials of an ultra-high molecular weight polyethylene composite material. The method comprises the following steps: placing the waste materials of the ultra-high molecular weight polyethylene composite material treated in a solvent into a specific mould; pressing into the wear-resistant lining boards on a press vulcanizer under the condition of a certain temperature and pressure. The waste materials of the ultra-high molecular weight polyethylene composite material are leftover materials generated when armor protection products are produced. The preparation method is simple, effective, low in processing difficulty, free of pollution and low in recovering cost, and does not need to separate fiber and resin; the performance of the wear-resistant lining boards prepared by adopting the preparation method is similar to that of the conventional ultra-high molecular weight polyethylene wear-resistant lining boards, and the wear-resistant lining boards have a great price advantage.

Description

technical field [0001] The invention relates to a method for preparing a wear-resistant liner by using ultra-high molecular weight polyethylene composite material waste, and belongs to the technical field of recycling ultra-high molecular weight polyethylene composite materials. Background technique [0002] In recent years, various violent and terrorist incidents at home and abroad have continued to occur, and the demand for protective equipment in the market is increasing. Various domestic companies that produce protective equipment are running at full capacity to produce protective equipment, and protective equipment Among them, ultra-high molecular weight polyethylene has become the main raw material due to its excellent protective function. With the increase of output, a large amount of ultra-high molecular weight polyethylene scraps are produced in the production process. The recovery of these scraps has become a big problem. [0003] At present, few scholars at home...

Problems solved by technology

The main reason is that ultra-high molecular weight polyethylene fiber has excellent anti-shock and anti-cutting functions, which makes the recycling cost of its composite products too high and difficult to recycle.

It was previously reported that some scholars tried to separate ultra-high molecular weight polyethylene and then spin it, but it was difficult to implement it because the resin was attached to the fiber and it was difficult to spin it again.
