Description
Technical Field
The invention relates to a composite material, in particular to a glass fiber reinforced polypropylene composite material.
Background
The polypropylene composite material taking the glass fiber as the reinforcing material has the advantages of light weight, high strength, good impact resistance, stable size and the like. In practical application, the polypropylene composite material is used for replacing traditional engineering plastics, steel plates, aluminum alloy and other materials.
In recent years, with the development of light weight of automobiles, glass fiber reinforced polypropylene composite materials are increasingly widely applied to the automobile industry due to the advantages of high specific strength, high cost performance and the like. The glass fiber reinforced polypropylene composite material is widely applied to interior trim parts and exterior trim parts such as instrument panel frameworks, seat frameworks, engine bottom guard plates, spare tire cover plates and the like in the automobile industry.
With the deep understanding of environmental awareness, people have higher and higher requirements on automobile odor. The glass fiber reinforced polypropylene composite material is used as a main material of automotive interior parts, and the smell of the glass fiber reinforced polypropylene composite material has great influence on the quality of air in an automobile. The quality of air in an automobile is poor, so that the riding experience of a user is influenced, and the body health of the user is adversely affected.
In order to limit the odor of interior materials, the manufacturers of the large automobiles in the world also take the research work and form the standard for regulating and controlling the volatile harmful substances. For example, the standard VW's PV3900 of the German public company adopts 1-6 grades of evaluation, the higher the grade is, the larger the smell is, and the grade less than or equal to 3 can meet the requirement.
Therefore, each automobile manufacturer pays more attention to the quality of air in the automobile, and demands for higher odor characteristics of materials used for automobile interior parts are made. In the glass fiber reinforced polypropylene composite material, in order to improve the combination with a polymer during the preparation of glass fibers, the glass fibers are coated with a wetting agent; the sizing agent contains small-molecule chemical substances such as amino silane, and part of amino silane is not combined with the glass fiber and is free on the surface of the glass fiber. Meanwhile, because the polypropylene material is a non-polar material and has poor compatibility with the glass fiber, a compatilizer such as unsaturated acid or unsaturated anhydride grafted polypropylene and the like can be added into a polypropylene composite material system to improve the compatibility of the polypropylene and the glass fiber; typically, the unsaturated acid or unsaturated anhydride grafted polypropylene will contain free unsaturated acid or unsaturated anhydride. The free aminosilane in the glass fiber sizing agent and the free unsaturated acid or unsaturated acid anhydride in the compatilizer can volatilize to influence the air quality in the automobile.
In the prior art, there are generally two measures to reduce odor. One is to replace the heavy-smelling additives with low-smelling substitutes. Secondly, adding an odor inhibitor or absorbent which comprises additives capable of carrying out physical adsorption, such as activated carbon, a glue stick, attapulgite, a molecular sieve, zeolite, bentonite, wollastonite and the like; and additives capable of chemical reaction, such as metal oxides and the like.
However, the above-mentioned measures for reducing the odor generally result in a reduction of some of the mechanical properties of the composite material. Therefore, it is important to develop a low-odor composite material with high cost performance.
