Abstract

The invention provides a low-odor polypropylene composite material which is characterized by being prepared from, by mass, 45%-97.6% of polypropylene, 0-40% of talcum powder, 0.4%-4% of an antioxidant, 1%-5% of an ethylene octene copolymer and 1%-5% of odor regulating master batch. The odor regulating master batch is polypropylene particles supported with an odor regulator with the mass fraction of 0.01%-1.5%, the odor regulator is a mixture of alcohols, ketones, esters and phenols with a boiling point of 90-190 DEG C. The composite material is simple in preparation process and free of influence on performance and has special fragrance.

Description

technical field

[0001] The invention belongs to the field of polymer materials, and relates to a polypropylene composite material, in particular to a low-odor polypropylene composite material and a preparation method thereof. Background technique

[0002] Polypropylene (PP) is a semi-crystalline thermoplastic. Both homopolymer and copolymer PP materials have excellent moisture absorption resistance, high impact resistance, and resistance to various organic solvent solubility. And acid and alkali corrosion resistance; it also has the advantages of low price, low density, easy processing, and reusability. However, PP has the disadvantages of large molding shrinkage, high low temperature brittleness, and easy aging. Therefore, physical or chemical modification technology is usually used, adding talc filler, glass fiber and other reinforcing materials, anti-light / thermal oxidation aging agent and other additives to improve the comprehensive properties of polypropylene materials...
