Halogen-free flame-retardant glass fiber reinforced nylon material, and preparation method therefor and use thereof

Abstract

Disclosed are a halogen-free flame-retardant glass fiber reinforced nylon material, and a preparation method therefor and the use thereof. The halogen-free flame-retardant glass fiber reinforced nylon material comprises 45-85 parts by weight of nylon, 10-55 parts by weight of glass fibers, 2-10 parts by weight of a phosphate flame retardant and 0.01-2 parts by weight of a terminal acetylenic acid ester modifier. The glass fibers and the phosphate flame retardant are bonded together by adding the terminal acetylenic acid ester modifier, which facilitates improving the candlewick effect in the glass fiber reinforced nylon material, and can also increase the compatibility of the nylon, the glass fibers and the flame retardant, such that the glass fiber reinforced nylon material having a very good flame retardant property can be obtained with a relatively low addition amount of the phosphate flame retardant without affecting the mechanical properties of the glass fiber reinforced nylon material itself, and finally, the halogen-free flame-retardant glass fiber reinforced nylon material having good flame retardant and mechanical properties is obtained.
