Abstract

The invention discloses a modified special material for manufacturing a flame-retardant turnover box and a preparation method of the modified special material. The modified special material is prepared from the following raw materials according to a ratio in parts by weight: HDPP, PVC resin, polyisoprene, pentaerythrityl tetrastearate, polyisobutene, PP-g-ST, polytetrafluoroethylene, glass fibers, ethylene glycol butyl ether, anhydrous calcium chloride, ethylene glycol, dioctyl adipate, activated calcium carbonate, titanium iso-propylate, hydroxypropyl methyl cellulose, a toughening agent, triphenyl phosphate, trimethylolpropane, a coupling agent, epoxy fatty acid butyl ester and chlorinated paraffin. According to the modified special material disclosed by the invention, the modification is performed by adding auxiliary components, and the flame resistance of products is improved to a larger extent on the premises that the properties of other materials are not influenced, and the cost is not increased; the modified special material obtained by the preparation method is good in toughness, and resistant to impact and facilitates processing of the turnover box with good flame retardance and the added values of the products are increased. With the adoption of the method disclosed by the invention, not only are qualified finished products effectively prepared, but also the operation process is very simple, and the mass production is facilitated.

Description

technical field [0001] The invention belongs to the field of macromolecule materials, and in particular relates to a modified special material for manufacturing a flame-retardant turnover box 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 traditiona...
