Polypropylene composite material with improved scraping and wiping resistance performance and preparation method thereof

Abstract

The invention discloses a polypropylene composite material with the improved scraping and wiping resistance performance, which is prepared from the following ingredients in percentage by weight: 75 to 97 percent of polypropylene, 2 to 20 percent of aedelforsite, 0 to 1.2 percent of scraping and wiping resistance agents, 0.1 to 2 percent of antioxidizers, 0.1 to 1 percent of light stabilizers and 0 to 3 percent of other accessory agents. The invention adds the inorganic filler aedelforsite in the basic recipe of the toughened polypropylene composite material, so the scraping and wiping resistance performance of the material is simultaneously improved on the basis of improving the mechanical property of the material. The invention has the advantages that 1, through adding the inorganic filler aedelforsite, the scraping and wiping resistance performance of the material is simultaneously improved on the basis of improving the mechanical property of the material; 2, the scraping and wipingresistance performance of the polypropylene composite material prepared by the invention is improved, and simultaneously, other use performance of the material is not influenced; and 3, the method for improving the scraping and wiping resistance performance of the polypropylene composite material provided by the invention has simple preparation process and low production cost.

Description

Technical field [0001] The invention relates to a polypropylene composite material with improved scratch resistance and a preparation method thereof. More specifically, a wollastonite filler is added by way of side feeding, which can simultaneously improve the mechanical properties of the material. Improve the scratch resistance of the material. Background technique [0002] Polypropylene is currently one of the most commonly used plastics because of its low density ((0.89-0.91g / cm 3 ), low price, non-toxicity, corrosion resistance, excellent electrical insulation performance, transparency and good processability, etc., are widely used in chemical, machinery, electricity, transportation and other industries. Among them, the application of polypropylene materials in automobiles has become one of the main research directions for the localization of parts in my country's automobile industry. However, the scratch resistance of polypropylene material is poor, and this performance is ...

Problems solved by technology

However, nanomaterials have small grains and large surface curvature, so the number of atoms arranged in disorder on the surface of the grains is much larger than the percentage of surface atoms in the crystalline material, and there are still atoms in the same nano-state grains Various defects make it easy to reunite at room temperature

As far as filled polypropylene is concerned, since polypropylene is a non-polar high polymer, compared with nano-particles, the polarity is very different and the compatibility is poor. It is difficult to obtain high performance without special treatment of nano-particle filled polypropylene material of construction
