Patent: An epoxy polymer material

China Coatings Online News: Patent: Epoxy polymer materials and their preparation methods and uses are disclosed. Application number: 201110354028.1; Public number: CN102504524A; Applicant: Changzhou University; Inventors: Zhang Hongwen, Zhu Jing, Jiang Yan, Yan Qiang. This product has both the advantages of complementary polyurethane-epoxy resin performance and the characteristics of polysilica oxide hydrophobic, with polysilicon modified polyurethane-epoxy resin polymer system preparation materials can be improved, mainly can be used in high damping materials, waterproof electronic packaging materials, medical materials and long-term storage materials.
the present invention relates to a polysilioxane modified polyurethane-epoxy polymer material and its preparation method and use. Drying polyether, biphenol type A epoxy resin and end hydroxyl polysilicagen raw materials to a moisture mass percentage of less than 0.01%, adding polyether, biphenol type A epoxy resin and diocycyanate to the reactor to produce polyurethane-epoxy Resin polymer system; polyurethane-epoxy polymer system with end hydroxyl polysilicon reaction to produce polysilioxane-polyurethane-epoxy resin prepolymer system; add curing agent and catalyst before the end of the reaction, stir well and pour into mold curing molding.
