Abstract

The invention discloses an anti-aging and anti-tension plastic and a preparation method thereof. The plastic comprises the following components in parts by weight: 52-67 parts of rubber, 21-28 parts of hydroxymethyl aliphatic amine, 16-34 parts of amyl acetate, 10-20 parts of tridecyl, 10-20 parts of zinc oxide and 20-30 parts of coupling agent. The preparation method of the anti-aging and anti-tension plastic is characterized by firstly putting the rubber, hydroxymethyl aliphatic amine and the coupling agent in a reaction vessel, stirring the materials to react the materials at 50 DEG C, heating after reacting for 60 minutes, gradually adding amyl acetate, tridecyl and zinc oxide, stirring the materials to react the materials, simultaneously heating to 120 DEG C to react the materials for 2 hours, and sending the reactant to an injection molding machine to undergo injection molding. The plastic has a reasonable formula. The preparation method is simple. The prepared plastic is anti-aging and anti-tension. Experiments prove that the tensile strength of the plastic is 27-30MPa and the 500h photo-aging impact strength retention rate is 100%.

Description

technical field [0001] The invention relates to an anti-aging and tensile-resistant plastic and a preparation method thereof, belonging to the field of plastic materials. Background technique [0002] Plastic material is a material with good performance. Because plastic has the advantages of light weight, no rust, and good insulation, it is used in many aspects of electronic product production. Plastic is easy to process, has good dimensional stability and surface gloss, and is easy to paint. Coloring, widely used in the field of electronic appliances. In recent years, in the electronic and electrical market, plastics maintain their position in the electronic and electrical market, and their anti-aging performance must be improved. However, the quality of plastics on the market is not stable, the anti-aging performance is not good, and they are still prone to aging, cracking, and reduced service life. Some plastics with better effects are made through complicated processes...
