Abstract

The invention provides a weather-proof anti-ultraviolet nylon material and a preparation method thereof, and relates to the field of polymer materials. The nylon material comprises the following components in parts by weight: 50-70 parts of caprolactam, 3-5 parts of a polyethylene and polyolefin elastomer mixture grafted with maleic anhydride, 3-5 parts of an ethylene-propylene-diene monomer (EPDM) grafted with maleic anhydride, 10-20 parts of a polyethylene and EPDM mixture grafted with maleic anhydride, 0.3-0.5 part of epoxy resin, 5-15 parts of thermosetting resin, 5-8 parts of a carbon fiber, 1-3 parts of 2,4-toluene diisocyanate, 1-3 parts of sodium hydroxide, 1-3 parts of nanometer zinc oxide, 0.5-1.5 parts of diphenylmethane diisocyanate, 2-5 parts of a flame retardant, 1-3.5 parts of a solid lubricant, 0.5-2 parts of a TDI curing agent, 0.5-1.5 parts of a plasticizer, 0.5-1.5 parts of a flexibilizer, 0.5-2 parts of a heat stabilizer and 0.2-0.5 part of benzotriazole. The nylon material is high in airtightness, heat stability and dimensional stability, and relatively high in stretching rate.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a weather-resistant and ultraviolet-resistant nylon material and a preparation method thereof. Background technique [0002] Because of its high mechanical strength, good wear resistance, and superior self-lubricating properties, nylon is widely used in industries such as auto parts, electronic appliances, and petrochemicals. However, the existing nylon materials have the disadvantages of poor light aging resistance, poor thermal stability and dimensional stability, and low elongation rate. It is difficult to carry out engineering applications in some strong ultraviolet light environments, so that its application range has been greatly restricted. Big restrictions. Contents of the invention [0003] In view of this, the present invention provides a weather-resistant and UV-resistant nylon material and a preparation method thereof, so as to improve the problems of poor thermal ...
