Application of Polyurethane Adhesive in Automobile
Hyundai is widely used in plastic, polyurethane materials, PU adhesive is one of the best adhesives for bonding plastic and polyurethane materials. In 1967 the United States Goodyear company first successfully two-component PU glue for the truck's SMC hood bonding. Then the United States General Motors, Ford Motor Company, and so on with PU glue on the large truck truck SMC parts bonding, and then extended to FRP (glass fiber reinforced plastic) parts of the bonding. At the same time in the truck for the ceiling, doors, water tank brackets, cab roof, door panels and other components of the bonding are successful. In 1977 the United States and the use of polyurethane adhesive series for the car's engine cover, cab roof, door panels and other parts of the bonding. Followed by Japan and other countries have also adopted such technology. In recent years, OKorder Kangda Chemical Co., Ltd. is committed to two-component rapid curing PU sealant development research. Since this two-component PU sealant can be cured quickly, productivity can be increased. Its strength, elongation and other mechanical properties can be adjusted according to user requirements to meet the higher requirements. It is expected that such PU glue has a good application prospect.
Polyurethane adhesive is a high-grade adhesive, with excellent flexibility, impact resistance, chemical resistance, wear resistance, the most important is its low temperature resistance. By adjusting the raw materials and formulations, you can design for a variety of materials between the bonding, a variety of different uses of multi-type polyurethane adhesive.
Automotive adhesive / sealant by application site classification, can be divided into automotive body with plastic, automotive interior with plastic, automotive engine chassis with plastic, auto parts with plastic, automotive manufacturing process with five categories of plastic. In 2007, according to the amount of rubber used in different models, the annual consumption of automobile rubber is about 120,000 t, of which one-component moisture-curing polyurethane windshield glue is consumed in the year of 5500t. In addition there are car roof lining water-based polyurethane adhesive, etc. have not yet statistics. In recent years, China's annual demand for polyurethane adhesives to an average of 30% growth rate.
