Efficent curing process of polyurethane material for automotive trim

Abstract

The invention discloses an efficient curing process of a polyurethane material for automotive trim. The efficient curing process comprises the following steps: S1, coating the surface of a polyurethane foaming material for the automotive trim with a wear-resistant coating; and S2, then feeding the material into a drying oven for curing. Curing is carried out in three stages, in the first stage, the curing temperature is 75-95 DEG C, and the curing time is 13-15 hours; in the second stage, the curing temperature is 103-117 DEG C, and the curing time is 5-7 hours; and in the third stage, the curing temperature is 85-95 DEG C, and the curing time is 8-12 hours. The efficient curing process of the polyurethane material for the automotive trim is simple in procedure, high in curing efficiency and good in curing effect, and the obtained product is excellent in wear resistance; there is little ordor, and body health is facilitated; and the foaming effect is good, foam holes are uniform, the elasticity is good, the mechanical property is high, the sound absorption and insulation effects are good, and the antibacterial effect is good.
