Abstract

The invention discloses a plastic box and a preparation method thereof. The plastic box is prepared from the following raw materials in parts by weight: 10 to 30 parts of polyethylene, 5 to 15 parts of polycaprolactone, 15 to 25 parts of cellulose, 5 to 10 parts of a photosensitizer, 7 to 15 parts of barium sulfate, 0.1 to 0.3 part of an antioxidant, 0.2 to 0.6 part of a dispersing agent, 0.2 to 0.6 part of a lubricating agent and 4 to 10 parts of an elastomer. The formula components are reasonable, the preparation method is simple, the added cellulose is easy to degrade, and the photosensitizer can absorb sunlight to accelerate degradation of a plastic packaging bag, so that the plastic box produced according to the method is easy to degrade, to reduce environmental pollution.

Description

technical field [0001] The invention relates to the field of plastics, in particular to a plastic box and a preparation method thereof. Background technique [0002] Plastic is a high molecular compound polymerized by addition polymerization or polycondensation reaction with monomer as raw material. It is commonly known as plastic or resin. It can freely change its composition and shape. , Colorants and other additives. [0003] The main component of plastic is resin. The term resin was originally named after the lipids secreted by animals and plants, such as rosin, shellac, etc. Resin refers to a polymer compound that has not been mixed with various additives. Resin accounts for about 40% to 100% of the total weight of the plastic. The basic properties of plastics are mainly determined by the nature of the resin, but additives also play an important role. Some plastics are basically composed of synthetic resins, with no or few additives, such as plexiglass, polystyrene,...
