The invention discloses a production process of a tpo stay wire body. The process comprises a step of subjecting n-butyl acrylate, PVC resin, triethyl aluminum, NBR and azobisisobutyronitrile to waterbath heating during which the temperature is increased to 50 DEG C at the speed of 18-20 min, then the temperature is increased to 60-65 DEG C immediately, the temperature is kept for 15 min, and then a product is taken out and subjected to vacuum drying; a step of selecting a high-pressure polymerization kettle, performing 4-6 times of pumping and discharging treatment on the high-pressure polymerization kettle through nitrogen, carrying out heating polymerization treatment on the treated n-butyl acrylate, PVC resin, triethyl aluminum, NBR and azobisisobutyronitrile at 78-82 DEG C, graduallyadding sodium dodecyl sulfate in the heating process, then adding an anti-aging agent with a content of 65% after 3 h of polymerization, mixing and terminating polymerization to obtain a primary emulsion composition; a step of adding an anti-aging agent and silver ion powder into the primary emulsion composition, mixing and stirring for 25 to 30 min at the temperature of 80 to 90 DEG C, then adding a Ca-Zn stabilizer and distilled water into the mixture, and carrying out reaction for 70-80 min. The use intensity is improved, so that the durability is enhanced.

The invention provides a composition for improving the plasticity retention rate of standard gel and a preparation method and application thereof.The composition is prepared from, by weight, 40-60 parts of an agent M, 1-3 parts of span 80, 0.5-1.5 parts of Tween 80, 0.3-1 part of peregal 0, 2-3 parts of lauryl sodium sulfate and 80-100 parts of water, and the agent M is prepared from styrenated phenol, 2, 6-butylated hydroxytoluene, N-(1, 2, 4-trimethyl-1, 3-pentanediol) and N-(1, 2, 4-trimethyl-1, 3-pentanediol. According to the present invention, the prepared composition can effectively improve the plasticity retention rate of the standard gel, the plasticity initial value P0 is 31.0-38.0, the plasticity retention rate PRI is improved to 63.1-67.6, the composition is applied to the dry stirring line or waterline preparation standard gel process, the addition amount of the composition can be effectively controlled, the production cost can be reduced, the production efficiency can be improved, and the production cost can be reduced. The plasticity retention rate is improved under the condition that the mechanical property is not changed, the difficulty of a plastication procedure and the production energy consumption in rubber product production are reduced, and the stability of a rubber production process formula and the performance is facilitated.
