Embodiment Construction

[0014] specific implementation plan

[0015] The present invention will be described in detail below through specific examples.

[0016] A nylon composite material resistant to ultraviolet light and anti-fading, made of the following raw materials in parts by weight (kg): sericite 10, phenyl salicylate 0.7, isocetyl palmitate 0.7, antioxidant DLTP 0.3, Polyacrylamide 2, o-hydroxybenzophenone 3, nylon 697, lithium chloride 3, epoxy resin E516, EVA emulsion 15, ethyl acetate 80, castor oil 2, ethylene / vinyl alcohol copolymer powder 6, distilled water 30 ;

[0017] A kind of anti-ultraviolet and anti-fading nylon composite material of the present invention is made by the following specific steps:

[0018] (1) Mix ethyl acetate, distilled water and EVA emulsion into the ultrasonic wave, ultrasonically disperse evenly, then add sericite and disperse at 90W ultrasonically for 10 minutes, after the end, heat the mixture to 90°C for 3 hours, during this process Stir and reflux, th...

Abstract

The invention discloses an anti-ultraviolet fading-resistant nylon composite material which is characterized by being prepared from the following raw materials in parts by weight: 8-11 parts of sericite, 0.5-1 part of phenyl salicylate, 0.5-1 part of isocetyl myristate, 0.2-0.4 part of an antioxidant DLTP, 1-2 parts of polyacrylamide, 2-3 parts of 4-hydroxybenzophenone, 90-100 parts of nylon 6, 2.5-3.2 parts of lithium chloride, 3-9 parts of epoxy resin E51, 10-15 parts of EVA emulsion, 60-80 parts of ethyl acetate, 1-3 parts of castor oil, 4-7 parts of ethylene / vinyl alcohol copolymer powder and 15-30 parts of distilled water. According to the invention, since the surface of a reinforcing body is wrapped and activated by the ethylene / vinyl alcohol copolymer, compatibility between the reinforcing body and the nylon 6 is improved, the reduction of the mechanical property of the nylon 6 is avoided, the added sericite has the effects of reducing resistance and lubricating, the mechanical strength of the material is enhanced, and the added 4-hydroxybenzophenone has the property of improving the ultraviolet resistance of the product and has the effects of fading resistance.
