Abstract

The invention discloses a cross-linked environment-friendly flame-retardant reinforced polyamide-based composite material and a preparation method thereof. The material comprises, by weight, 20 to 80parts of aliphatic polyamide, 10-40 parts of glass fibers, 10 to 20 parts of a flame retardant, 0.5 to 10 parts of a main cross-linking agent, 0.5 to 10 parts of an auxiliary cross-linking agent, 0.5to 10 parts of a compatilizer, 0.1 to 0.3 part of a coupling agent, 0.1 to 0.3 part of a lubricating agent and 0.1 to 0.3 part of an antioxidant. The mechanical properties and thermal properties, especially the thermal deformation temperature, of the cross-linked environment-friendly flame-retardant reinforced polyamide-based composite material prepared from the raw materials are integrally improved by 30% or above; the mechanical property and the thermal property, especially the thermal deformation temperature, are integrally improved by 15% or above, the strength of the weld line is improvedby adopting the preparation method, and the risk of damage caused by cracks in the use process of the material is reduced to a great extent.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and relates to the technical field of preparation of a cross-linked environmentally friendly flame-retardant reinforced polyamide-based composite material, in particular to a cross-linked environmentally friendly flame-retardant reinforced polyamide-based composite material and a preparation method thereof. Background technique [0002] Polyamide (commonly known as: nylon) is one of the five major engineering plastics. It has excellent physical and mechanical properties such as high strength, high modulus, corrosion resistance, and low temperature resistance. It is currently widely used in the fields of automobiles, home appliances, and electronic appliances. In the field of electronics and electrical appliances, the flame retardancy of nylon is relatively good, and it is generally required to add flame retardants to achieve the flame retardancy of nylon. Especially in some special fiel...
