Abstract

The invention relates to an anti-aging master batch and belongs to the field of chemical engineering formulas. The anti-aging master batch is composed of following raw materials, by weight, 20-30 parts of polyethylene, 20-40 parts of polypropylene, 20-30 parts of a photo-stabilizer, 5-20 parts of a filler, 1-2 parts of a dispersing agent and 2-4 parts of a coupling agent. The anti-aging master batch is greatly improved in use performance, has excellent social and economical benefit, is suitable for polypropylene flexible freight bags or woven bags having anti-aging requirement, can effectively inhibit thermo-degradation of polypropylene in processing, and delaying thermo-oxidative aging and photo-aging during use.

Description

technical field [0001] The invention relates to an anti-aging masterbatch, which belongs to the field of chemical process formula. Background technique [0002] At present, the anti-aging ability of polypropylene container bags is poor, and there is no special anti-aging masterbatch on the market. At present, all kinds of products need anti-aging treatment, and all kinds of packaging bags, container bags, etc. need to undergo anti-aging Only after processing can the required indicators be achieved; [0003] Plastic products made of pure polyethylene resin are easy to age, especially under the condition of light or heat [0004] The speed is faster. In order to improve the anti-aging performance of polyethylene, additives such as light stabilizers and antioxidants are usually added to polyethylene resin, but the application of anti-aging additives for polyethylene is not simply adding and accumulating. It is a unified system that needs to be considered comprehensively to en...
