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.

Embodiment Construction

[0012] In order to make the present invention more comprehensible, preferred embodiments are described in detail as follows.

[0013] The invention provides a method for preparing an explosion-proof plate by using ultra-high molecular weight polyethylene composite material waste. This recycling method has the advantages of simple process, low recycling cost, no pollution, and no need to separate fibers and resins. The ultra-high molecular weight polyethylene explosion-proof board prepared by this method has excellent performance, which is not much different from the common composite material explosion-proof board in the market and has a very obvious price advantage, which meets the current requirements of the development of circular economy.

[0014] Concrete steps of the present invention are:

[0015] The first step is to adjust the temperature of the upper and lower plates of the vulcanizer to 170±5°C, set the time to 3600±100s, and set the pressure to 15±0.5Mpa. The vulc...

Abstract

The invention provides a method for preparing an anti-explosion plate from ultra-high molecular weight polyethylene composite material waste. The method comprises the following steps: putting the ultra-high molecular weight polyethylene composite material waste treated in a solvent into a mold corresponding to the anti-explosion plate in shape; and pressing into the anti-explosion plate on a press vulcanizer at certain temperature and pressure, wherein the ultra-high molecular weight polyethylene composite material waste is a leftover material which is generated when armor protection products are produced. The preparation method provided by the invention is simple, effective, low in processing difficulty, free of pollution, free of fiber and resin separation and low in recovery cost; compared with an anti-explosion plate prepared from a composite material in the market, the anti-explosion plate prepared by adopting the method is not large in difference of property and has the great price advantage.

Description

technical field [0001] The invention relates to a method for preparing an explosion-proof plate by utilizing 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 recycling of these scraps has become a major problem. [0003] At present, few scholar...
