Circulation box material and preparation method thereof

Abstract

The invention discloses a circulation box material and a preparation method thereof, and belongs-the technical field of plastic products. The circulation box material is mainly prepared from, by weight, 100-150 parts of high-density polyethylene, 15-25 parts of polypropylene, 2-10 parts of polyacrylonitrile carbon fibers, 10-15 parts of a filler, 2-10 parts of a pigment, 10-25 parts of a compatibilizer, 0.5-3.5 parts of a dispersant, 0.2-0.7 parts of an antioxidant, 0.1-0.6 parts of an antibacterial agent, 0.3-0.6 parts of a coupling agent and 0.2-0.6 parts of a stabilizer. Circulation boxes made through adopting the method have the advantages of large mechanical strength, uniform color and strong antibacterial property, and are suitable for loading and transporting refrigerated and frozen foods.

Description

technical field [0001] The invention belongs to the technical field of plastic products, and in particular relates to a turnover box material and a preparation method thereof. Background technique [0002] With the development of the transportation industry and the container industry, convenient and safe transportation can ensure the quality of transportation and reduce transportation costs, which makes turnover boxes play an important role in the entire transportation process. Refrigerated and frozen food is always in a specified low temperature environment in the production, storage, transportation, sales, and consumption links to ensure food quality and reduce food loss. At present, the turnover box used for low-temperature food in the market is mainly made of expandable polystyrene foam. Because of its light weight, non-toxicity, it can be molded, has the advantages of low water absorption, low temperature resistance and cheap price. , widely used in food transportation...

AI Technical Summary

Problems solved by technology

However, due to its insufficient hardness, poor plastic, obvious directionality, large internal stress and poor structure of the turnover box, the strength of the turnover box is reduced, brittle and easy to crack, and the loss is serious after repeated handling in logistics transportation, which is not conducive to long-term use. added shipping costs

In addition, traditional turnover boxes have poor antibacterial properties, and due to poor distribution of colorants or fillers, plastic or pigment discoloration and uneven color on the surface of plastic parts affect the appearance of turnover boxes
