Processing equipment and processing method of PVC (Polyvinyl Chloride) sealing material with high elasticity for automobiles

Abstract

The invention relates to the technical field of production manufacturing of automobile parts, in particular to processing equipment and a processing method of a PVC (Polyvinyl Chloride) sealing material with high elasticity for automobiles. The processing equipment comprises a material processing box, wherein a stirring device is mounted on the top part of the material processing box; a water bathheating box is mounted at the bottom of the stirring device; and a heat exchange box is mounted at the bottom of the water bath heating box. According to the processing method, the following materials are adopted in parts by weight: 60g to 80g of PVC, 10g to 50g of powder butyronitrile rubber, 10g to 20g of a plasticizer, 5g to 15g of a heat stabilizer, 0.5g to 1g of a lubricant, 3g to 8g of an inorganic filler, 10g to 20g of a coloring agent, and 4g to 7g of a vulcanizing additive. According to the processing equipment and the processing method disclosed by the invention, through arrangementof the material processing box, a stirring motor, a rotating shaft and stirring blades, the mixing efficiency can be improved; through arrangement of a feeding hopper and a feeding pipe, the raw materials can be conveniently added, and spattering of the raw materials is prevented; meanwhile, through arrangement of a discharging pipe and a discharging control valve, output of a mixed material is conveniently controlled; and through arrangement of a water-bath heating box, the raw materials are heated more uniformly, a stirring effect is better and the mixing quality of the raw materials is improved.

Description

technical field [0001] The invention relates to the technical field of production and manufacture of automobile parts, in particular to a processing equipment and a processing method of a high-elasticity PVC sealing material for vehicles. Background technique [0002] Automobile sealing strip is one of the important parts of automobiles. It is widely used in doors, windows, body, sunroof, engine box and backup (luggage) box and other parts. It has the functions of sound insulation, dustproof, water seepage prevention and shock absorption. Maintain and maintain the small environment in the car, thus playing an important role in protecting the occupants, electromechanical devices and accessories in the car. [0003] At present, most of the automobile sealing strips are made of vulcanization, protection, reinforcement, operating system materials and special endowment materials (such as coloring agents, foaming agents) added to PVC materials to form dense glue (including black g...

AI Technical Summary

Problems solved by technology

Due to the higher price of rubber, the cost of the sealing strip is higher

The cost of PVC material is low, and it has the characteristics of high elasticity. At the same time, the processing technology is simple, beautiful, environmentally friendly, comfortable and does not affect its performance. It is the development direction of automobile sealing strip materials; today's PVC sealing materials have low processing efficiency and uneven heating.
