Abstract

The invention discloses a low-odor and low-volatility automobile interior trim polypropylene composite material and a preparation method. The composite material is prepared from the following components by weight: 100 parts of polypropylene, 10-35 parts of inorganic filler, 5-15 parts of toughening agent, 0.2-0.8 part of coupling agent, 0.2-0.8 part of antioxidant, 0.2 part of light stabilizer ~0.8 parts, lubricant 0.2~1 part, POSS material 2~5 parts, liquid distilled water 1.5~3.5 parts, toner 0.3~1.0 parts. In the present invention, when performing twin-screw extrusion granulation, the vaporization of liquid distilled water into water vapor can take out the small molecules in the matrix material to reduce the odor and volatile matter of the composite material; by adding POSS material to form it with polypropylene The interpenetrating network structure improves the scratch resistance of the composite material, and the POSS material has high hardness, migration resistance, and odorless properties, which will not bring odor and volatile matter to the polypropylene composite material.

Description

Technical field: [0001] The invention relates to the field of polymer material modification, in particular to a low-odor, low-volatility, scratch-resistant automotive interior polypropylene composite material and a preparation method. Background technique: [0002] Cage polysilsesquioxane (POSS for short) is a new class of real molecular level organic / inorganic hybrid nanomaterials in recent years, and its general molecular formula is (RSiO 1.5 ) n , n is generally 6, 8, 10, 12, etc., among which n is 8 is the most typical. POSS has both the nanometer size and cage structure of inorganic nanoparticles, and has the advantages of organic polymers, such as: [0003] 1. The POSS inorganic silicon-oxygen skeleton structure determines its outstanding heat resistance, flame retardancy and radiation resistance; [0004] 2. POSS can improve the toughness of polymers, because POSS nanoparticles can terminate the development of microcrack tips, and can cause silver crazes or shear b...
