Abstract

The invention discloses a wood-fiber-toughened poly dimethyl terephthalate automotive interior material and a preparation method thereof. According to the interior material, poly dimethyl terephthalate, ramie, modified wood fiber and fullerene are used as main ingredients, and calcined kaolin, hydroxyethyl methyl cellulose ether, basalt fiber, calcined talc, 3-triethoxysilylpropylamine silane, cordierite, nano-zinc oxide, aluminum triphosphate, erucyl amide, talcum powder and other inorganic and organic materials are selected to act synergistically with the main ingredients. The automotive interior material is light, safe, environmentally friendly, resistant to scrubbing, good in toughness and high in strength.

Description

technical field [0001] The invention belongs to the field of automobile interior materials, and in particular relates to a wood fiber toughened polyethylene dimethyl terephthalate automobile interior material and a preparation method thereof. Background technique [0002] With the improvement of the living standards of Chinese residents, people's demand for cars that can improve their lives is also increasing. The car interior is an important part of the car. [0003] Automotive Interior mainly refers to the automotive products used in the interior modification of the car, involving all aspects of the car interior, such as car steering wheel covers, car seat cushions, car floor mats, car pendants, interior decorations, storage boxes, etc. Interior products. The car interior we call in China is actually the Interiors System in English. Because this part of auto parts has a certain degree of decoration, the usual translation in the industry is called "car interior". Howeve...
