[0045] Mix the components such as polypropylene copolymer, polyethylene, thermoplastic elastomer, talcum powder, tiger skin elimination additive, lubricant, composite light and heat stabilizer, coloring agent in the mixer according to the weight ratio in Table 1 Evenly, the mixed material is fed into the twin-screw extruder from the feeder. The temperature of the twin-screw extruder from the feeding section to the head is: 190°C, 210°C, 220°C, 220°C, 220°C ℃, 220℃, 220℃, 220℃, the temperature of the die is: 230℃. After high-speed twin-screw (screw speed: 800r / min) shearing and mixing, extruding from the machine head, drawing, air cooling, pelletizing, drying and packaging, the finished polypropylene modified material is obtained, which can completely eliminate Tiger-print polypropylene composite.

Abstract
The invention discloses a polypropylene composite material capable of completely eliminating tiger wrinkle defects and a preparation method and application thereof. The composite material is prepared from, by weight, 50-80% of polypropylene, 1-10% of polyethylene, 1-20% of thermoplastic elastomer, 10-30% talcum powder, 0.2-5% of compound thermal stabilizer, 0.1-3% of lubricant, 1-10% of tiger wrinkle defect eliminating assistant and 0-5% of colorant. The preparation method of the polypropylene composite material capable of completely eliminating the tiger wrinkle defects can be achieved by adopting an existing double-screw extruder. The specific raw materials and the tiger wrinkle defect eliminating assistant are adopted to prepare the polypropylene material having excellent impact resistance performance, the requirements of medium-grade and high-grade automobile interior and exterior ornaments can be met, meanwhile the material is used for manufacturing high-grade automobile interior and exterior ornaments or complicated-structure parts, does not produce tiger wrinkle defects completely, can completely replace imported materials, conforms to the domestication development tendency of automobile materials and is wide in market prospect.
Description
technical field [0001] The invention relates to the technical field of polypropylene composite materials, in particular to a polypropylene composite material capable of completely eliminating tiger skin patterns and its preparation method and application. Background technique [0002] Polypropylene is a general-purpose thermoplastic with excellent comprehensive performance. It has the characteristics of low price, light weight, solvent resistance, good elasticity, rigidity, easy recycling, and non-toxicity. It is the most important lightweight material for automobiles. The quality of parts is about 40%, and it can also reduce the procurement cost by about 40%. It has been widely used in automotive interior parts, such as instrument panels, door panels, pillars, bumpers, etc. In addition to light weight, the appearance of automotive interior and exterior trims is a public concern. The appearance of parts such as instrument panels, door panels, wheel eyebrows, and door sills i...
