Rubber blends theory is accompanied by a blend of practice came into being. Although these theories still in the process of continuous development and improvement, they are showing an important guiding role in the production practice. In summary these theories are: ① polymer compatibility theory; morphology theory ② rubber blends; ③ rubber blend components co-crosslinking polymer theory; Rubber Blends of TPE? theory. Progress in implementing methods and blending modification of rubber blends according to the state of rubber and synthetic resin which when blended with blending the following three methods: A total of ravioli melt, Fu L total liquid mixed solution blending. The method of melt blending a mix of synthetic rubber or after the synthetic resin is heated to a molten state. Melting and mixing in the mixing machine or extruder, which is a method widely used in industrial production. Fu L liquid polymer blend is a method of mixing an emulsion state, such as the NBR / PVC blends. In recent years, low molecular weight compounds or oligomers With blended with rubber modified to achieve research, more and more attention. These low molecular weight compounds or oligomers generally contain active reactive atom or group, such an atom or group capable of grafting vulcanization process or blend with the rubber macromolecules occurs in the blending process, block copolymerization or cross-linking reaction, which play the role of rubber-modified. This blend is called reactive modified rubber modified ^^ mix. Rubber and low molecular or oligomer blend, not only can improve the mechanical strength of the rubber, but also can improve other properties, such as natural rubber blended with maleic anhydride to produce maleic anhydride grafted natural rubber copolymer, to be vulcanized plastic modulus increased by more than 10 times the number of dynamic fatigue bending mention Gao nearly three orders of magnitude, heat aging resistance also significantly improved. Another example is the low-nitrile rubber blended with polyacrylate, the former in the presence of an initiator capable of crosslinking reaction with the latter, not only significantly improve the mechanical strength of the vulcanized nitrile rubber, nitrile rubber and also improves the metal bonding strength. Low molecular weight oligomers and flower care or rubber products for translational modification, is complementary to the non-reactive modification technology, with the commercialization of many low molecular weight compounds and oligomers, this modified technique prospects are very promising.
