Unsaturated polyester resin is one kind of thermosetting plastics. It is widely used in many fields such as construction, transportation, chemical industry, electron, watercraft, aviation, space flight etc.
　　After modified by nanometer material, its many capabilities can be improved effectively. For examples: modulus of elasticity, bending strength, distortion temperature, hardness, heat-resistant, anti-corrosive, re-ultraviolet, and anti-aging etc.
Usually the nanometer materials are added into finished resin. Because the disperse character and combining strength with chemical bond are weak, it’s limited to improve the capabilities.
　　In our company, the nm-SiO2 is added into the materials of polyester and polymerized on original-locate. The disperse character and combining strength are improved and its many capabilities are improved too. The content of mn-SiO2 in resin is 3-5%, and the modified resin is also transparent.
　　The result of examination: after modified with mn-SiO2 in this method, many capabilities of unsaturated polyester resin are improved. The hardness increased is improved 43-50%, the distortion temperature is increased 35-50%, the bending strength is increased near 100%, and the modulus of elasticity is increased about 50%. The nm-SiO2 is the globosity and dispersed uniformly inside UP with particle size of 10～40nm.
　　In order to obtain different capability, YCIC can put different nanometer materials into the different resin, such as mn-SiO2, mn-TiO2, mn-Al2O2, and cascade.
