Problems solved by technology

[0004] There have been some reports on reducing the glossiness of polypropylene (PP) composite materials. The Chinese patent application No. CN201010591416.7 mentioned a method to maintain low glossiness by adding styrene-acrylonitrile (SAN) copolymers, but The compatibility of SAN and PP is poor, which will easily lead to material delamination, affecting the performance and anti-aging ability of the material itself
The Chinese patent application No. 201110144142.1 realizes the matting effect by adding rubber powder, but the rigidity of polypropylene itself is poor, and adding too much rubber powder will further affect its rigidity and reduce the practicability of the polypropylene material itself

Abstract

The invention discloses a delustering polypropylene composite material and a preparation method thereof. The dulling polypropylene composite material comprises the following components in mass percent: 60-80% of polypropylene, 2-20% of flexibilizer, 5-20% of compatilizer, 5-25% of organic delustering agent, 0.5-5% of inorganic delustering agent, 0.1-2% of antioxidant and 2-20% of inorganic filler. The dispersion effect of delustering components in the polypropylene is strengthened through preparing master batch, the polypropylene, the delustering agent, the inorganic filler and part of compatilizer are firstly co-blended and then extruded through a dual-screw extruder to prepare the delustering master batch, and then the delustering master batch is co-blended with polypropylene and other components, and then extruded to prepare the delustering polypropylene composite material. The delustering polypropylene composite material is excellent in delustering performance, suitable for injection molding of various delustering products, can be applied to indoor decoration and automotive upholstery and can be used for preventing glare from generating in daily life.

Description

technical field [0001] The invention relates to the field of thermoplastic resin composite materials in polymer material technology, in particular to a matting polypropylene composite material and a preparation method thereof. Background technique [0002] Polypropylene is a general-purpose thermoplastic widely used in daily life, commonly known as "pleated glue". Because of its low price, excellent performance, and good formability, it is often prepared into various electrical housings, containers, and automotive interiors by injection molding. With the popularity of automobiles, consumers and automobile manufacturers are paying more and more attention to the quality of automotive interior parts. If the interior parts used in the cab have a high gloss, strong reflections and glare will occur in areas with strong sunlight Phenomenon, affect the driver's normal driving and comfort, so automotive interior parts require lower gloss. Among the materials used for daily househol...
