The characteristics or the functions of the raw materials of the support rod are as follows:
polyvinyl chloride: vinyl chloride monomer in peroxide, azo compound and other initiators; or a polymer polymerized by a free radical polymerization mechanism under the action of light and heat. The molecular weight is generally within the range of 10-11 ten thousand, the polydispersity is relatively large, the molecular weight increases with the reduction of polymerization temperature; without a fixed melting point, softening begins at 80-85 ℃, the temperature of 130 ℃ becomes a viscoelastic state, and the temperature of 160-180 ℃ begins to change into a viscous state; has better mechanical property.
Phenolic resin: also called as bakelite, also called as bakelite powder. The original material is colorless or yellow brown transparent material, is insoluble in water, and is stable to water, weak acid and weak base solution. Has good acid resistance, mechanical property and heat resistance, and can be widely applied to corrosion-resistant engineering.
Carboxyl nitrile rubber: the carboxylated nitrile rubber is prepared by ternary polymerization of butadiene, acrylonitrile and organic acid (acrylic acid, methacrylic acid and the like). The carboxyl is introduced to increase the polarity, so that the compatibility of the polyvinyl chloride and the phenolic resin can be increased, the synergistic effect is realized, the high strength can be endowed, the good adhesion and aging resistance are realized, the wear resistance and the tear strength are improved, and the oil resistance is further improved.
