Problems solved by technology

[0003] The traditional imitation metal texture effect is generally realized by post-processing methods after injection molding, such as painting, varnishing, lamination, transfer printing, etc., which are costly and not environmentally friendly; in recent years, with the development of material technology and mold technology, spray-free imitation The preparation technology of metal texture effect is also improved. Through patent search, the existing spray-free metal texture effect PP composite materials generally adopt the compound method of pearl powder + metal powder (gold, silver powder), and the addition ratio is high, which is inevitable in the molding process. There will be weld marks, which will affect the appearance of the product

Embodiment 1

[0043] Example 1 Preparation of Spray-free, High Rigid Metal Texture Effect PP Composite Material

[0044] According to the raw material formula in Table 1, various raw materials were weighed, among which PP resin (under the condition of 200°C / 10kg, its melt index was 35g / 10min, and its specific gravity was 0.905g / cm 3 ), mineral powder (mica powder, mesh number 1500-2000 mesh, treated with polypropylene-maleic acid acyl graft, wherein the addition of polypropylene-maleic acid acyl graft is 2%) and toughening agent POE (specific gravity 0.86-0.91g / cm 3 , melt index>1g / 10min, elongation at break>900%).

[0045] Before use, add mineral powder, aluminum powder, silver flash powder, antioxidant, and special dimethyl silicone oil in sequence, and stir at a low speed for 1-3 minutes, then add PP resin, toughener, and color masterbatch, and stir at a low speed for 2-5 minutes Then stir at a high speed (650-1300rpm) for 3-5 minutes; the mixed material is melted and granulated to obt...

Abstract

The invention discloses a polypropylene composite material with a spraying-free and high-rigidity metal texture effect and a preparation method thereof and belongs to the technical field of macromolecular engineering plastics. The composite material is prepared from the following raw materials in parts by weight: 60-85 parts of polypropylene resin, 5-15 parts of toughener, 15-30 parts of mineral powder, 2-4 parts of color master batch, 0.3-1 part of lubricant, 0.5-1.5 parts of aluminum powder, 0.25-1 part of bright silver powder and 0.2-0.4 part of antioxidant. According to the polypropylene composite material and the preparation method thereof, physical properties of the polypropylene composite material are reasonably regulated, and the added aluminum powder and bright silver powder can enable the metal-imitating effect of the alloy material to meet the operating requirements of electrical appliance products on appearance, so that the polypropylene composite material has the advantages of good environment-friendliness, high smoothness, and the like.

Description

technical field [0001] The invention relates to the technical field of polymer engineering plastics, in particular to a polypropylene composite material with spray-free and high-rigidity metal texture effects and a preparation method thereof. Background technique [0002] Polypropylene PP is one of the five general-purpose engineering plastics. Its excellent heat resistance, chemical temperature resistance, weather resistance and easy processability are widely used in electronic appliances, automobiles and other industries; with the development of polypropylene compound modification technology, PP Modified composite materials, as an important plastic-substituting steel material, are more and more used in exterior structural parts such as automobiles and home appliances. [0003] The traditional imitation metal texture effect is generally realized by post-processing methods after injection molding, such as painting, varnishing, lamination, transfer printing, etc., which are c...
