Problems solved by technology

[0002] As one of the five general-purpose plastics, polypropylene plastic has the advantages of abundant sources, light weight, low price, and good processing performance compared with other plastics. Therefore, it is widely used in industries such as automobiles, home appliances, machinery, and construction, but outdoor polypropylene products Exposure to air is prone to discoloration, chalking, surface cracking, loss of luster and decline in mechanical properties. Therefore, its use as structural materials and engineering plastics will be greatly limited

Embodiment 1

[0011] An anti-aging polypropylene plastic, the anti-aging polypropylene plastic is composed of the following raw material components in parts by weight: 100 parts of polypropylene, 0.5 part of antioxidant 1010, 0.2 part of light stabilizer, 0.25 part of ultraviolet absorber, carbon 38 parts of black, 3 parts of nano-titanium dioxide, 14 parts of epoxy resin, 18 parts of melamine, 0.4 parts of dispersant, and 0.7 parts of coupling agent. The preparation method is as follows: mixing the raw materials into an ultra-high-speed mixer and mixing them evenly, melting and extruding the mixture through a twin-screw mixing equipment to make granules, and then injecting and molding it through an injection molding machine.

Embodiment 2

[0013] An anti-aging polypropylene plastic, the anti-aging polypropylene plastic is composed of the following raw material components in parts by weight: 100 parts of polypropylene, 0.4 part of antioxidant 1010, 0.1 part of light stabilizer, 0.2 part of ultraviolet absorber, carbon 37 parts of black, 2.5 parts of nano-titanium dioxide, 13 parts of epoxy resin, 16 parts of melamine, 0.3 parts of dispersant, and 0.6 parts of coupling agent. The preparation method is as follows: mixing the raw materials into an ultra-high-speed mixer and mixing them evenly, melting and extruding the mixture through a twin-screw mixing equipment to make granules, and then injecting and molding it through an injection molding machine.

Embodiment 3

[0015] An anti-aging polypropylene plastic, the anti-aging polypropylene plastic is composed of the following raw material components in parts by weight: 100 parts of polypropylene, 0.6 part of antioxidant 1010, 0.3 part of light stabilizer, 0.3 part of ultraviolet absorber, carbon 40 parts of black, 4 parts of nano-titanium dioxide, 16 parts of epoxy resin, 20 parts of melamine, 0.6 parts of dispersant, and 0.8 parts of coupling agent. The preparation method is as follows: mixing the raw materials into an ultra-high-speed mixer and mixing them evenly, melting and extruding the mixture through a twin-screw mixing equipment to make granules, and then injecting and molding it through an injection molding machine.

Abstract

The invention relates to an anti-aging polypropylene plastic comprising the following raw materials in parts by weight: 100 parts of polypropylene, 0.4-0.6 part of an antioxidant 1010, 0.1-0.3 part of a light stabilizer, 0.2-0.3 part of an ultraviolet light absorber, 36-40 parts of carbon black, 2-4 parts of nano titanium dioxide, 12-16 parts of epoxy resin, 15-20 parts of melamine, 0.2-0.6 part of a dispersant and 0.5-0.8 part of a coupling agent. According to the anti-aging polypropylene plastic disclosed by the invention, nano titanium dioxide with good dispersibility in the polypropylene plastic and melamine are added to ensure that the prepared polypropylene plastic has flame-retardant properties, meets requirements for outdoor use, and has good impact resistance, anti-aging performance and improved toughness.

Description

technical field [0001] The invention belongs to the technical field of plastics, in particular to an anti-aging polypropylene film. Background technique [0002] As one of the five general-purpose plastics, polypropylene plastic has the advantages of abundant sources, light weight, low price, and good processing performance compared with other plastics. Therefore, it is widely used in industries such as automobiles, home appliances, machinery, and construction, but outdoor polypropylene products Exposure to air is prone to discoloration, powdering, surface cracking, loss of luster and decline in mechanical properties. Therefore, its use as structural materials and engineering plastics will be greatly limited. Contents of the invention [0003] The object of the present invention is to provide an anti-aging polypropylene plastic. [0004] The purpose of the present invention can be achieved through the following technical solutions: [0005] An anti-aging polypropylene p...
