A kind of composite material for pp/hdpe furniture and preparation method thereof

Abstract

The invention provides a composite material for PP / HDPE furniture and a preparation method thereof. The composite material comprises the following raw materials in parts by weight: 80-100 parts of polypropylene, 10-30 parts of high-density polyethylene, and 5-15 parts of matting agent 1-3 parts of weather resistance agent, 1-5 parts of reinforcing agent, 1-5 parts of toughening agent, 1-10 parts of compatibilizer and 0-6 parts of auxiliary agent; matting agent is modified by diene thermoplastic elastomer The cross-linked polyvinyl chloride, the above raw materials are pre-mixed and granulated to prepare composite materials. The advantage of the present invention is that the special cross-linked structure of the modified cross-linked polyvinyl chloride has matting properties, and the refractive index difference between it and polypropylene and high-density polyethylene can further reduce the glossiness of the composite material, endow the composite material Excellent matting performance; modified cross-linked polyvinyl chloride as a matting agent can not only matt but also improve the acid and alkali resistance of the composite material; the composite material for furniture proposed by the invention has a simple preparation process and low cost, and is suitable for Furniture decoration materials with high gloss requirements or automotive interior and outdoor table and chair materials, etc.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a composite material for PP / HDPE furniture and a preparation method thereof. Background technique [0002] Polypropylene (PP) has high tensile strength, good heat resistance and chemical stability, outstanding processability and bending fatigue resistance. It is a widely used general-purpose plastic, commonly used in furniture decoration materials , automotive interior materials and outdoor tables and chairs and other fields. With the wide application of polypropylene, the strong plastic feeling brought by high gloss lowers the grade of overall home decoration and car interior, etc. In order to meet people's needs, it is meaningful to develop PP composite materials with low gloss. [0003] Various methods are used in the prior art to reduce the glossiness, and the common one is to add an inorganic matting agent to the composite material, such as patent CN200710171710...

AI Technical Summary

Problems solved by technology

[0006] In order to overcome the above-mentioned defects that the polypropylene composite material in the prior art uses a matting agent, which may adversely affect other properties, such as low impact resistance and poor weather resistance. In addition, too high or too low matting properties will reduce the material. aesthetic feeling, the present invention provides a kind of PP / HDPE furniture composite material, the specific technical scheme adopted is:
