Abstract

The invention relates to a glass fiber reinforced halogen-free flame-retardant PA6 (Poly Amide 6)/PS (Poly Styrene) alloy material and a preparation method thereof. The PA6/PS alloy material is prepared from the following raw materials in parts by weight: 20 to 60 parts of PA6 resin, 15 to 30 parts of PS resin, 10 to 25 parts of flame retardant, 2 to 6 parts of flame retardant synergist, 6 to 12 parts of compatilizer, 0.2 to 0.6 part of coupling reagent, 0.3 to 0.8 part of antioxidant, 0.3 to 0.8 part of lubricant and 10 to 30 parts of glass fibers. Compared with the prior art, the PA6/PS alloy material provided by the invention has the characteristics of good comprehensive mechanical performance, good flame retardance, stable size, low warping, oil resistance, high-temperature resistance, excellent machining performance and the like. Thus, the PA6/PS alloy material can be conveniently applied to the fields of electric appliances, automobiles, mining machinery and the like.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a glass fiber-reinforced halogen-free flame-retardant PA6 / PS alloy material and a preparation method thereof. Background technique [0002] PA6 (polycaprolactam) is a crystalline polymer made from amino acids or corresponding lactams. Because it contains -CO-NH-groups, it has good mechanical properties, abrasion resistance and chemical resistance. It is used in engineering The field of plastics occupies an important position. However, the strong polar groups in the PA6 molecular chain cause its disadvantages such as high water absorption, low low-temperature impact strength, and dimensional instability, which limit the application field of PA6. [0003] PS (polystyrene) refers to an amorphous non-return polymer formed by free radical polycondensation of styrene monomers. The output is second only to PE, PVC, and PP. PS has excellent transparency, processing performance and elect...
