[0004] The comfort of existing car seat cushions is not good. On the one hand, it is reflected in the elasticity and material of the seat cushion body. On the other hand, there is a deviation between the seat cushion film and the seat cushion body. It is separated from the seat cushion film. After the seat cushion is foamed and molded, the seat cushion film is wrapped and sewed on the outside, which is not only inefficient, but also has poor bonding

[0050] see figure 1 , a kind of preparation technology of ETPU seat pad, comprises the following steps:
[0051] Step 1, mold pretreatment, spray a layer of release agent and a layer of in-mold paint in the cavity of the front and rear molds successively. The material of the front and rear molds is 7075 high-strength aluminum alloy, which can improve the precision of the mold and prolong the service life of the mold , the technicians design the appropriate number and position of air holes on the mold according to the structure of the product, which can make the material better fused, improve the yield of the product, and maintain the characteristics of the material at the same time;
[0052] Step 2, hang the film, after spraying a layer of release agent in the front and rear mold cavities, wrap the seat cushion film before hanging on the front mold, and wrap the seat cushion film after hanging symmetrically on the rear mold, wrap the seat cushion film and the rear The wrapped...

Abstract
The invention discloses a preparation process of an ETPU seat cushion, which belongs to the technical field of seat cushions. The preparation process of an ETPU seat cushion comprises the following steps: Step 1, mold pretreatment; Step 2, film-hanging; Step 3, injecting ETPU Raw materials; Step 4, temperature control and heating; Step 5, the first autoclaving, releasing the steam pressure from the front mold pores; Step 6, the second autoclaving, releasing the steam pressure from the rear mold pores; Step 7, the third autoclaving At the same time, the steam pressure is released from the air holes of the front mold and the rear mold; step 8, cooling and solidification; step 9, molding and stripping, which can realize the raw materials for producing seat cushions and the wrapped seat cushion film at the same time in the prefabricated mold for three times steaming Pressing, so that the wrapped seat cushion film and the seat cushion are better combined, and the raw material is ETPU material. After the autoclaving process, hot melt adhesive is coated on the joint of the wrapped seat cushion film, and the wrapped seat cushion film is also bonded when the ETPU is formed. As a whole, the combination is higher, and the preparation efficiency is significantly improved.
