Problems solved by technology

In recent years, due to the improvement of living standards, consumers have higher requirements for the comfort of automobiles. Therefore, in order to meet the needs of consumers, automobile manufacturers have improved the interior decoration of automobiles and the sealing of compartments. It caters to the needs of consumers, but at the same time it also makes it difficult for air pollutants in the car to diffuse, thus polluting the environment in the car
In order to reduce costs and improve market competitiveness, some automobile manufacturers even use non-green and environmentally friendly decorative materials, which aggravate the air pollution in the car and cause the drivers and passengers in the car to experience driving syndrome such as depression, irritability, and inability to concentrate. , some even have traffic accidents, this is what people often call invisible killers

Abstract

The invention provides a polyester fiber material used for automobile interior decorative parts, and a preparation method thereof. The polyester fiber material comprises PET, an acrylonitrile-styrenecopolymer, hydroxyl silicone oil, a modified porous adsorption material, a compatilizer, a lubricant, a heat stabilizer, and an anti-impact modifier. The preparation method comprises following steps:PET, the acrylonitrile-styrene copolymer, hydroxyl silicone oil, the modified porous adsorption material, the compatilizer, the lubricant, the heat stabilizer, and the anti-impact modifier are mixed,are delivered into a high speed mixer, are heated to 90 to 130 DEG C for stirring, are cooled, and are discharged; an obtained mixture is delivered into a screw extruder for extrusion granulation so as to obtain particles; and the particles are subjected to injection moulding so as to obtain a finished product. According to the preparation method, PET is taken as a main raw material, and the modified porous adsorption material is added, so that the automobile interior decorative part material excellent in performance and low in VOC is obtained.

Description

technical field [0001] The invention relates to the technical field of materials for automotive interior parts, in particular to a polyester fiber material for automotive interior parts and a preparation method thereof. Background technique [0002] With the familyization of automobiles, the social problems caused by automobile pollution are becoming more and more serious. In addition to the exhaust gas pollution affecting people's daily life, the pollution inside the car is also increasingly affecting people's health. The emission level of pollutants volatilized by non-metallic materials used in automotive interior parts and interior decoration plays a decisive role in the air quality in the car. In recent years, due to the improvement of living standards, consumers have higher requirements for the comfort of automobiles. Therefore, in order to meet the needs of consumers, automobile manufacturers have improved the interior decoration of automobiles and the sealing of com...
