Abstract

The invention discloses a pass box prepared from recycled and modified waste PP plastic woven bags and a preparation method thereof. The pass box is prepared from the following raw materials by weight: crushed waste PP plastic woven bags, HDPE, PVC resin, PP-g-MAH, oleamide, glass fiber, bis(stearoyloxy)propoxy borate, glycerol, active calcium carbonate, glycol, flexibilizer, a coupling agent, octadecylamine, silicone powder, ethylene-vinyl acetate copolymer and acetone. The preparation method for the pass box is simple and can be easily implemented; the mechanical properties and processing properties of the prepared pass box meet requirements; meanwhile, since the waste PP plastic woven bags are used as the raw material, cost is low, good economic benefits are obtained, and reasonable utilization of resources and environmental protection are benefited.

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 PP 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...
