Information
People's Daily Online, March 6th. Recently, the high-end automotive-grade polyvinyl butyral resin (PVB resin) masterbatch developed by Shanghai Petrochemical has officially started industrial production, which will break the monopoly of high-end PVB resin manufacturing industry in China by foreign countries. Situation.
 
It is understood that PVB resin is formed by the condensation reaction of polyvinyl alcohol (PVA) resin and n-butyraldehyde under acid catalysis, and is widely used in automotive safety glass, building safety glass, solar photovoltaic module packaging film, coating, primer, ink and other fields. , Large market demand and high added value.
 
At present, only a few companies in the world can produce high-quality PVB resins that can be used in automotive safety glass. With the development of China's automobile industry, the demand for automotive-grade PVB interlayer films is increasing, while the production of domestically produced high-quality film raw material PVB resin is extremely low, and it is heavily dependent on foreign imports.
 
打破 In order to break the foreign monopoly market, the Ministry of Chemical Industry of Shanghai Petrochemical has set up a professional technical research and development team to carry out joint research, continuously optimize the scientific process, and gradually improve various technical indicators of PVB resin. After ten years of research and development, high-end automotive-grade PVB resin masterbatches have finally come out. The new PVB resin products produced by this masterbatch have reached the international advanced level of similar products in technical indicators such as transparency, light resistance, cold resistance, water resistance, film formation and impact resistance. Its melt index, yellowing index, etc. The indicators can also be compared with products from developed countries such as the United States, Japan, and Europe. (Shen Wenmin, Zhu Le, Zhuoping)
