Abstract

The invention provides a polyamide compound material and a production technology thereof. The polyamide compound material comprises the following components of, in parts by weight, 78.4-13% of high-viscosity polyamide, 10-20% of low-viscosity polyamide, 0.2-2% of a thermal stabilizer, 1-6% of a compatilizer, 10-35% of glass fibers, 0-10% of talcum powder, 0-10% of whiskers, 0.2-2% of inorganic toner and 0.2-2% of another assistant. According to the polyamide compound material and the production technology thereof, the high-viscosity polyamide and the low-viscosity polyamide are adopted for compounding, the proper glass fibers, talcum powder, whiskers, compatilizer, assistant and inorganic toner are added to make the produced polyamide compound material capable of resisting high and low temperature, good mechanical performance is maintained, meanwhile, good surface appearance is obtained, and the rigidity and the tenacity of the material are improved so that the mechanical performance of the material can be maintained for a long term, change of material color is reduced, and the polyamide compound material can be applied more widely.

Description

technical field [0001] The invention relates to the field of materials, in particular to a polyamide composite material and a preparation method thereof. Background technique [0002] Polyamide is commonly known as polyamide (Nylon), English name Polyamide (referred to as PA), density 1.15g / cm 3 , is a general term for thermoplastic resins containing repeating amide groups -[NHCO]- on the main chain of the molecule, including aliphatic PA, aliphatic-aromatic PA and aromatic PA. Among them, aliphatic PA has many varieties, large output and wide application. According to the number of carbon atoms contained in diamines and dibasic acids or amino acids, a variety of different polyamides can be prepared. There are dozens of polyamide varieties, among which polyamide-6, polyamide-66 and polyamide Amide-610 is the most widely used. [0003] Polyamide 6 is the most commonly used material in engineering plastics. It has good mechanical properties and chemical resistance, and is w...
