Abstract

The invention discloses a marbleizing free-spraying polypropylene composite material and a preparation method as well as application. The free-spraying polypropylene composite material comprises the following components in percentage: 58.4-82.6 percent of polypropylene, 10-30 percent of glass fiber, 6-8 percent of compatibilizer, 0.2-0.3 percent of lubricant, 0.2-0.3 percent of antioxidant, 0.5-2 percent of color powder and 0.5-1 percent of spot black pigment. The polypropylene, the compatibilizer, the lubricant, the antioxidant, the color powder and the spot black pigment are uniformly stirred and then added into a main feeding hopper of a parallel twin screw extruder; adding the glass fiber into a lateral feeding hopper and performing blend melt extrusion to obtain the marbleizing free-spraying polypropylene composite material. The free-spraying polypropylene composite material has the advantages of high strength, high rigidity, low carbon, environment friendliness, low cost, high temperature resistance, corrosion resistance and easiness in dispersion. The preparation process is simple, the cost is low, and the comprehensive physical and mechanical performance is superior.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a marble-like non-spraying polypropylene composite material, a preparation method and application thereof. Background technique [0002] "Low-carbon environmental protection, energy saving and emission reduction" is one of the important issues in the development of today's society. For product manufacturers, it is necessary to consider the use of green and environmentally friendly materials from the design and development stage. This is not only the need for enterprise product upgrading and technological innovation , and embodies the corporate social responsibility. In order to obtain gorgeous, colorful, and diverse appearances, spraying paint on plastic substrates is usually used to achieve bright, beautiful, and special-effect appearances. However, the spraying process has disadvantages such as complicated process, high cost, polluting the environment, endangering ...
