Preparing method of plate material for vehicle

Abstract

The invention discloses a preparing method of a plate material for a vehicle. The preparing method comprises the following steps of S1, conducting preparation, wherein raw materials are weighed respectively, resin in the raw materials is grinded respectively, then pre-melting is conducted to obtain premixed resin, and then glass fiber and carbon fiber are cut into sections and grinded to obtain mixed fiber; S2, adjusting the rotation speed of a mixing mill, raising temperature of the mixing mill to 320-340 DEG C, then adding a plasticizer, a stabilizer and an antistatic agent, increasing the rotation speed after the materials are uniformly mixed, then adding zinc stearate, calcium stearate, molybdenum disulfide and the mixed fiber in sequence, and then reducing the temperature to obtain a mixed glue material; S3, adding the mixed glue material into an injection molding mold, and conducting pressure maintaining, cooling molding and demolding to obtain the plate material. According to the preparing method of the plate material for the vehicle, the process is simple, the raw materials are easy to mix, few waste is generated, the percent of pass is high, the production efficiency is high, and the prepared plate material is stable in performance, moderate in rigidity, not prone to deformation and fracture, and good in corrosion resistance and wear resistance.

Description

technical field [0001] The invention relates to the technical field of auto parts materials, in particular to a preparation method of an auto plate material. Background technique [0002] Along with the raising of people's living standard, automobile has become one of common means of transportation in people's daily life. As car sales increase, so does the supply pressure on the car production industry. Among the many components of the car, the panels play a vital role. The panels used in the car are mainly steel and plastic materials, especially plastic materials, such as automotive interiors, door inner and outer shells, and front bumper brackets. Such parts are usually made of plastic. Compared with steel materials, plastic materials are lighter in weight and lower in production cost, so they are widely used in automobile production. However, during the use of the car, we often find some disadvantages of the plastic plate, such as easy to scratch, brittle, easy to defo...

However, during the use of the car, we often find some disadvantages of the plastic material, such as easy to scratch, brittle, easy to deform and break

Moreover, in the production process of plastic material panels, the pass rate of products is low and the rework rate is high, resulting in waste of materials and reduction of production efficiency
