Environment-friendly material for automotive interiors and preparation method thereof

Abstract

The present invention discloses an environment-friendly material for automotive interiors and a preparation method thereof. The material comprises, by weight, 20-35 parts of natural resin, 10-15 parts of cotton fiber, 10-20 parts of seaweed fiber, 2-10 parts of bast fibre and leaf fibre, 20-40 parts of olive oil, 4-10 parts of corrosion inhibitor, 5-15 parts of nanoscale molybdenum trioxide, 2-5 parts of a flame retardant, and 5-10 parts of PPA. The corrosion inhibitor comprises, by weight, 10-15 parts of zinc carbonate, 2-10 parts of tuff, 5-10 parts of vermiculite. The flame retardant comprises, by weight, 6-15 parts of sepiolite powder, 5-8 parts of stearic acid, 2-5 parts of molybdenum trioxide, 1-5 parts of ruthenium oxide, and 50-100 parts of water. The environment-friendly material for automotive interiors has the advantages of excellent tensile strength, flexural strength and impact strength, and the product has a good appearance. The material has strong corrosion resistance and flame retardance, which ensures safety. Raw materials are easy to obtain, production processes are simple, and production costs are low.

Description

technical field [0001] The invention relates to an environment-friendly material for automobile interior decoration, in particular to an environment-friendly automobile interior decoration material and a preparation method thereof. Background technique [0002] The interior parts of a car generally refer to parts and materials such as partitions, door trim panels, instrument panel assemblies, armrests, and carpets in the car compartment. Compared with other parts on the car, they have little effect on the running performance of the car, but their face can be seen at a glance, representing the image of the whole car, which one is better, determines the reputation and grade of the car, and determines the choice of people. car intent. In addition, for cars, although the interior parts are only some auxiliary parts, they have to undertake functions such as vibration reduction, heat insulation, sound absorption and sound insulation, which play a very important role in the comfor...

Problems solved by technology

There are many kinds of environmental protection materials for automobile interior decoration, and the use experience and effect are also uneven. Although some have high service life, high strength and good wear resistance, the raw materials are not easy to obtain and the production process is complicated, which makes the product price Higher; some have poor corrosion resistance and poor flame retardancy, which seriously affect the quality of the product
