Abstract

The invention relates to an environment-friendly fireproof PA6 composite material. The environment-friendly fireproof PA6 composite material is prepared from the following raw materials: polyamide PA6resin with a viscosity of 2.0, a flame retardant brominated polystyrene resin, a synergistic flame retardant antimonous oxide, an anti-dripping agent PTFE, chopped glass fibers, a high-adsorption deodorizing extractant, an antioxidant and a light stabilizer. According to the invnetion, a high-adsorption extraction machine is used for extracting and wrapping low-molecular-weight volatile organic compounds together in a molten state in a double-screw extruder; under the action of heating and shearing, contacting, mixing, mutual dissolution and extraction are carried out, and a large number of microbubbles containing VOC components are formed through gasification with heat and are pumped away and removed through double vacuum pumps under the action of strong negative pressure. According to the environment-friendly fireproof PA6 composite material disclosed by the invention, the content of low-molecular volatile matters such as volatile organic compounds is reduced from the source, so thepurpose of eliminating bad smell is achieved.

Description

technical field [0001] The invention relates to an environment-friendly fireproof PA6 composite material and a preparation method thereof, belonging to the technical field of material preparation. Background technique [0002] As a means of transportation, cars have entered more and more families, and everyone is paying more and more attention to health issues. The detection of volatile organic compounds (VOC) has become a routine key detection item for major OEMs, and the odor detection of automotive materials is getting more and more attention. According to the research results, it is found that in midsummer, the internal temperature of a closed car will reach about 65°C within 15 minutes. And under the front windshield of direct sunlight, the temperature far exceeds 65°C. Such a high temperature will stimulate the release of pollution from many sources of pollution. If you do not pay attention to this invisible killer, it will cause great harm to the health of the driv...
