Abstract

The invention relates to a polyamide resin composite material with good flexibility and low temperature resistance and a preparation method thereof, which belong to the technical field of polymers. The invention discloses the polyamide resin composite material with good flexibility and low temperature resistance. The material is prepared from the following components in parts by mass: 80 parts ofnylon, 15-25 parts of ABS resin, 10-20 parts of a compatilizer, 15-30 parts of glass fiber, 0.1-2 parts of a coupling agent, 0.5-2 parts of a cold-resistant additive, 0.1-1.5 parts of an antioxidant and 0.1-2 parts of a processing aid, and is prepared by uniformly mixing the components in two steps and then granulating the mixture by a twin-screw extruder. When the polyamide resin composite material with good flexibility and low temperature resistance is prepared, the compatilizer, the ABS resin and the cold-resistant additive are used, so that the flexibility is improved, the low temperatureresistance of the resin material is greatly improved, the problem of brittleness of nylon resin at a low temperature is solved, and the polyamide resin composite material can be used at a low temperature; meanwhile, the inorganic filler is added, so that the rigidity of the composite material is improved, and the composite material has a wider application range.

Description

technical field [0001] The invention belongs to the technical field of polymer material modification, and in particular relates to a polyamide resin composite material with good flexibility and low temperature resistance and a preparation method thereof. Background technique [0002] As the earliest variety of engineering plastics, nylon is widely used in chemical industry, electrical appliances, automobiles due to its high strength, high modulus, excellent chemical resistance and wear resistance, high melting point and low friction coefficient and other machinery manufacturing fields. However, in more demanding application fields and further research, nylon is brittle at low temperature and dry state, which greatly limits its application. For example, the traditional nylon 66, nylon 610 and nylon 612 have high crystallinity, and in the dry state at low temperature, although their mechanical strength is guaranteed, they are obviously brittle. [0003] Due to the sharp decl...
