Abstract

The invention discloses a glass fiber reinforced nylon material for an engine intake manifold and a preparation method thereof. The glass fiber reinforced nylon material comprises the following raw materials: 20-40 parts of nylon resin No. 1, 20-40 parts of nylon resin No. 2, 30-35 parts of glass fibers, 0.5-1 part of a coupling agent, 0.2-0.5 part of a main antioxidant, 0.2-0.5 part of an auxiliary antioxidant, 0.2-0.5 part of a heat stabilizer, 3-5 parts of metal microbeads, 0.1-0.3 part of a nucleating agent, 0.3-0.8 part of a lubricant, 1.0-1.5 parts of a hydrolysis-resistant agent, 0.5-2.5 parts of epoxy resin and 1-2 parts of black masterbatch. The invention also discloses the preparation method for the above-mentioned nylon material. According to the invention, the epoxy resin is adopted for coating pretreatment of the metal microbeads, and the metal microbeads flow onto the surface of the material during the subsequent processing of the nylon material, thereby improving the gloss of the obtained product and reducing the phenomenon of emergence of glass fibers on the surface. Thus, the prepared intake manifold has a smooth surface and good use performance.

Description

technical field [0001] The invention belongs to the technical field of nylon materials, in particular to a glass fiber reinforced nylon material used for an engine intake manifold and a preparation method thereof. Background technique [0002] In the wave of automobile lightweight revolution, the replacement of traditional aluminum alloys with plastic substrates for automobile intake manifolds can not only achieve lightweight, but also have a better surface finish than traditional aluminum alloy intake manifolds. High intake efficiency. The application of glass fiber reinforced nylon 6 composite material to the intake manifold of automobile engine not only reduces the weight of the intake manifold of the engine but also reduces its production cost. The surface characteristics of automotive plastic intake manifolds require that the plastic itself can well solve the problems of surface holes, mold filling and glass fiber exposure. [0003] In the prior art, the nylon 6 glass...
