Abstract

The invention discloses an aging-resistant PP (polypropylene) lunch box. The aging-resistant PP lunch box is prepared from the following raw materials in parts by weight: 80-90 parts of polypropylene, 20-30 parts of bisphenol A type polycarbonate, 20-30 parts of nano-calcium carbonate, 2-4 parts of stearic acid, 5-10 parts of talcum powder, 5-10 parts of carbon black, 10-15 parts of modified attapulgite, 2-3 parts of azodicarbonamide, 1-2 parts of vinyl tris(beta-methoxyethoxy) silane, 0.5-0.8 part of antioxidant CA, 0.5-0.8 part of anti-aging agent MB, 2-4 parts of propanetriol triglycerol acid ester, 1-2 parts of maleic anhydride, 0.5-1 part of zinc borate, 0.4-0.6 part of polyethylene wax and 1-2 parts of isooctyl thioglycolate dimethyl tin. The lunch box produced according to the invention has the advantages of light weight, bright and smooth surface, good chemical resistance, good dimension stability, high temperature resistance, aging resistance, high impact resistance, low breakage rate and the like.

Description

technical field [0001] The invention relates to an aging-resistant PP lunch box and a manufacturing process thereof, belonging to the technical field of plastic product production. Background technique [0002] Polypropylene (PP plastic) is another excellent resin variety developed after nylon. It is a linear polymer with high density, no side chains, and high crystallinity, and has excellent comprehensive properties. The dinner plate made of PP plastic has the characteristics of light weight, bright and calm surface, good chemical resistance, excellent chemical stability and electrical insulation, and non-toxic. It also has low impact strength and tensile strength, and insufficient rigidity. , Easy to age, become brittle, easy to deform, easy to break and other shortcomings. Contents of the invention [0003] The purpose of the present invention is to provide an anti-aging PP lunch box and its manufacturing process to improve the comprehensive performance of the PP plas...
