Problems solved by technology

Existing plastic products have poor oxidation resistance. As time goes by, plastic products will change color, become brittle, and reduce the finish due to oxidation during use, which will affect the aesthetics and performance of plastic products, and sometimes even give people Therefore, it is necessary to conduct further research on the oxidation resistance of plastics to improve the aesthetics and performance of plastic products

Embodiment 1

[0042] An anti-aging plastic granule, comprising the following components by weight: 70-90 parts of polyethylene, 30-40 parts of EPDM rubber, 20-30 parts of polycarbonate, 5-15 parts of polyetherimide 5-15 parts of polyimide, 5-10 parts of antioxidant, 5-10 parts of toughening agent, 2-5 parts of coupling agent, 2-5 parts of dispersant, 2-5 parts of stabilizer, plasticizer 1-5 parts of anti-aging agent and 2-5 parts of anti-aging agent.

[0043] The antioxidant is one of antioxidant 1076, antioxidant CA, antioxidant DNP, and antioxidant DLTP, and the dispersant is monoglyceride stearate or microcrystalline paraffin.

[0044] The stabilizer is calcium stearate, epoxy resin or zinc stearate, and the plasticizer is dioctyl phthalate, dibutyl phthalate or diisononyl phthalate.

[0045] The anti-aging agent is nano titanium dioxide, and the particle size of the nano titanium dioxide is 20-60nm.

[0046] see figure 1 , a preparation method of anti-aging plastic particles, compris...

Abstract

The invention discloses an anti-aging plastic particle and a preparation method thereof and belongs to the technical field of plastic processing. The anti-aging plastic particle comprises polyethylene, ethylene propylene diene monomer, polycarbonate, polyetherimide, polyimide, an antioxidant, a flexibilizer, a stabilizer, a plasticizer, an anti-aging agent and the like. The preparation method comprises the steps of material preparation, blending, extrusion granulation, cooling, packaging and the like. According to the invention, polyethylene, ethylene propylene diene monomer and polycarbonateare adopted as raw materials to prepare the plastic particles; so that the tensile strength is high, the resilience force is high, and the flame-retardant performance is excellent; the anti-aging plastic particle disclosed by the invention has the advantages of simple preparation process, low production cost, suitability for mass production, high temperature resistance, dimensional stability, highstrength resistance, wide long-term use temperature range, excellent mechanical property and good fireproof property.

Description

technical field [0001] The invention relates to the technical field of plastic processing, and more specifically relates to an anti-aging plastic particle and a preparation method thereof. Background technique [0002] Plastic has the characteristics of light weight, no rust, good insulation and so on, so it is widely used in daily life. Plastic products can be seen everywhere in daily life, and its application fields are very extensive, and all fields cannot be completely separated from plastic products. Existing plastic products have poor oxidation resistance. As time goes by, plastic products will change color, become brittle, and reduce the finish due to oxidation during use, which will affect the aesthetics and performance of plastic products, and sometimes even give people Therefore, it is necessary to conduct further research on the oxidation resistance of plastics to improve the aesthetics and performance of plastic products. Contents of the invention [0003] 1....
