Example

[0037] Examples 1~5

[0038] The copolymer polypropylene (i.e. propylene-ethylene block copolymer polypropylene), polyethylene, talc, thermoplastic elastomer, scratch-resistant additives, lubricants, composite light and heat stabilizers and other components are in parts by weight in Table 1. The mixing ratio is uniformly mixed in the mixer to obtain the mixed material. The mixed materials are 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℃, 210℃, 220℃, 220℃, 220℃, 220℃, 220℃, 230℃, the temperature of the die is 230℃. After high-speed shearing and mixing by a twin-screw extruder (screw speed of 800r / min), extrusion, drawing, air cooling, pelletizing, drying and packaging by the machine head, a polypropylene composite product is prepared.

Abstract

The invention discloses a polypropylene composite material for a car seamless dashboard. The polypropylene composite material consists of the following raw materials in percentage by weight: 50-70% of propylene-ethylene block co-polypropylene, 3-10% of polyethylene, 5-30% of a thermoplastic elastomer, 5-30% of talcum powder, 0.5-3% of a composite photo-thermal stabilizing agent, 0.1-1% of a lubricating agent, 0.5-4% of anti-scratch additives and 0-5% of a coloring agent. The polypropylene composite material for the car seamless dashboard can show excellent low-temperature impact resistance, particularly, can be used for meeting the multi-axial low temperature impact performance of fracture toughness at -35 DEG C, also has the characteristics such as scratch resistance, weather resistance and low total carbon, and can be used for meeting the requirements of a high-grade car seamless blasting dashboard. The invention also discloses a preparation method of the polypropylene composite material. The preparation method is simple to operate, does not need special equipment, is low in cost, and is suitable for industrial production.

Description

technical field [0001] The invention relates to the field of polymer composite materials, in particular to a polypropylene composite material, a preparation method thereof, and an application in preparing an automobile seamless instrument panel. Background technique [0002] Automobiles are one of the most important means of transportation in modern society. In 2013, the national automobile production and sales were 22.1168 million and 21.9841 million, an increase of 14.8% and 13.9% respectively over the previous year. However, automobiles are large energy consumers. In order to save energy, the automobile industry will develop in the direction of energy conservation, environmental protection, and safety in the future. According to reports, 1% weight loss of general auto parts can save 1% fuel; this requires that the used auto materials have the characteristics of light weight, simple processing, and easy recycling. [0003] Polypropylene is a general-purpose thermoplastic ...
