Abstract

The invention discloses a spraying free thermal conductive nylon material for LED lighting products and a preparation method thereof, and relates to the polymer material field. The nylon material comprises following raw materials in parts by weight: 40 to 60 parts of polyamide, 5 to 10 parts of a flexibilizer, 30 to 50 parts of thermal conductive powder, 1 to 8 parts of a metal pigment, 0.5 to 1.0part of a coupling agent, 0.2 to 0.6 part of an antistatic agent, and 0.2 to 0.6 part of an antioxidant. By adding a metal pigment into raw materials, an LED lighting product prepared from the nylonmaterial has metal luster and metal texture; the paint spraying is eliminated, the production process is simplified; the processing cost of the LED lighting product is reduced; the environment pollution caused by the spraying technology is avoided, and the health of operators is protected.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a spray-free thermally conductive nylon material for LED lighting products and a preparation method thereof. Background technique [0002] With the improvement of living standards, LED lighting lamps with energy-saving effects have gradually become a common lighting method. At present, the commonly used materials of LED lighting lamps are nylon, polycarbonate, polybutylene terephthalate, polypropylene, phenolic resin, etc. Among them, nylon is an important engineering plastic. Compared with other materials, nylon It is more suitable for thermal conductivity modification. The modified thermal conductive nylon has the advantages of good thermal conductivity and heat dissipation, and easy processing and molding. At present, more and more nylon materials are used in the production of LED lighting products. After nylon materials are used in LED lighting products, in order to make the...
