Abstract

The invention discloses a formula of a composite material for an automobile interior part. The formula consists of the following materials in percentage by weight: 40 to 60 percent of polylactic acid fiber and 40 to 60 percent of natural fiber. The production method of the invention comprises the following steps: uniformly mixing the raw materials; putting the mixture into an opener for opening, combing and shaping the obtained product, feeding the product into a lapping machine for cross lapping and feeding the cross-lapped product into a needling machine for needling to form a felt; immersing the fiber felt into a processing slurry; drying the immersed coiled material through hot blast and cutting the dried material into pieces of required size; placing the cut material into a mould for curing and shaping by heating; demoulding the material to form a composite plate; and softening the composite plate by flat panel heating, covering the plate with a surface decorative layer and performing cold molding on the plate through a product mould to manufacture the finished product finally; or softening the cut fiber felt by the flat panel heating directly, covering the plate with the surface decorative layer and performing the cold molding to manufacture the finished product finally. The composite material for the automobile interior part of the invention has the advantages of no toxicity, no pollution, simple processing technique, small energy consumption and high environment protection performance.

Description

technical field [0001] The invention belongs to the field of manufacturing automobile interior parts, and discloses a composite material for automobile interior parts and a production method thereof. Background technique [0002] In recent years, with the enhancement of people's awareness of environmental protection, the development of degradable materials is an important way to solve the problem of environmental pollution. Therefore, countries all over the world are paying more and more attention to fully biodegradable materials. Existing automotive interior products mostly use chemical synthetic materials (such as PP, PU and glass fiber, etc.), which are limited in resources, non-renewable, consume a lot of energy, and are easy to cause harm to the human body during processing. Wastes after use are difficult to degrade in the natural environment, causing increasingly serious pollution to the natural environment. This not only affects people's daily life, but also brings ...
