Abstract

The invention discloses a pass box prepared from recycled and modified waste PE plastic woven bags and a preparation method thereof. The pass box is prepared from the following raw materials by weight: crushed waste PE plastic woven bags, HDPE, polybutyl rubber particle, PP-g-MAH, oleamide, glass fiber, fatty acid ester, calcium stearate, active calcium carbonate, glycol, white carbon black, octadecylamine, flexibilizer, silicone powder, dioctyl adipate, polyvinyl alcohol and acetone. According to the invention, the waste HDPE PE plastic woven bags are utilized in the formula, so product cost is greatly reduced; the preparation method is simple, can easily realize industrial production and effectively overcomes the problems of environmental pollution and waste of resources caused by waste and old plastic; the prepared pass box has high notch impact strength, bending strength and hardness; and with the method provided by the invention, the qualified pass box can be effectively prepared, operation process is simple, and large-scale production can be conveniently carried out.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a regenerated and modified turnover box for waste PE plastic woven bags and a preparation method thereof. technical background [0002] Plastic turnover boxes are running boxes and logistics boxes produced from plastic. Plastic turnover boxes belong to the type of packaging and turnover materials. Most of the existing plastic turnover boxes on the market are made of HDPE (low pressure high-density polyethylene) and PP (polypropylene) with high impact strength as raw materials for one-time injection molding. The production and application of plastic turnover boxes in my country is not long, but it has developed extremely rapidly in the past ten years. Now it has almost completely replaced the traditional wooden turnover box, and has been widely used in food and logistics production sites. The reason why plastic turnover boxes can quickly replace traditional wooden tu...
