Wood flour-filled modified polypropylene material with low odor and imitation flocking effect, and preparation method thereof

Abstract

The invention discloses a wood flour-filled modified polypropylene material with low odor and an imitation flocking effect, and a preparation method thereof. The wood flour-filled modified polypropylene material is prepared from the following components in percentage by weight: 40 to 99 parts of polypropylene resin, 0 to 40 parts of ore body powder, 0 to 20 parts of flexibilizer, 0.5 to 10 parts of wood flour, 0.1 to 1 part of antioxidant, and 0.1 to 0.5 part of light stabilizer. Compared with the prior art, the wood flour-filled modified polypropylene material provided by the invention has the following positive effects that (1) the wood flour is adopted to replace chemical staple so as to be added into the light-colored modified polypropylene material, a texture design is combined to have the imitation flocking effect, and a wood flour grid or a hollow structure can adsorb odor, so that not only is the material odor reduced, but also a light wooden fragrance can be produced. The material can replace an interior trim part product coated with textile fabrics, so that not only is the production cost of auto parts manufacturers saved, but also the high requirements of consumers on smell and vision effects of automotive interior trims are greatly met. (2) Less wood flour is added, so that the wood flour is not easy to precipitate out and has no influence on a physical performanceof the material.

Description

technical field [0001] The invention relates to the technical field of designing polymer material modification, and in particular relates to a wood powder-filled modified polypropylene material with low odor and imitation flocking effect and a preparation method. Background technique [0002] Polypropylene has become one of the most important general-purpose plastics because of its light weight, low price, easy processing and good overall performance, and it is also the plastic raw material with the fastest growing consumption in the automotive field in the past ten years. Modified polypropylene materials have been widely used in automotive interior parts, mainly including instrument panels, door panels, pillars and glove boxes, etc., and are usually covered with textile fabrics to improve the quality of automotive interior parts. However, the process is complicated, reducing production capacity, increasing costs, and the textile fabric and adhesives used will enhance the od...
