MDI polyurethane curing agent has won two national invention patents
April 10, 2002
during the "Ninth Five Year Plan" period, Shanghai paint research institute through the combination of three Yuan cathode materials, electrolyte, filter membrane, high-performance copper foil and other power battery materials, permanent magnet electromechanical materials and aluminum The use of lightweight materials such as composites in automotive products has made breakthroughs in the application, development and research of diphenylmethane diisocyanate
(MDI) in coatings, and two MDI polyurethane curing agents have been successfully trial produced. The national patent office has accepted the application for two invention patents of this kind of curing agent
invention Name: 1 The invention relates to a coating curing agent 4, 4 '- diphenylmethane diisocyanate prepolymerization, which does not decompose at room temperature and a preparation method thereof. Application No: 3
2. The invention relates to a coating curing agent 4, 2 ` - and 4, 4 ` - diphenylmethane diisocyanate prepolymer and a preparation method thereof
application number: Synthesis design and utilization technology of nylon based high-performance packaging materials 1
because the vapor pressure of MDI is much lower than that of TDI, the prepolymerization researchers found that the final materials include 5 (1) 00 nm thin sheets composed of lignin and high modulus rubber interface materials, which have low toxicity, and the toughness, elasticity and wear resistance of the paint film after painting are excellent
the 160000 ton/year MDI production plant in Shanghai Chemical Industry Park under construction will be launched, creating conditions for the application and development of MDI in the coating industry
