AI Technical Summary

Benefits of technology

This patented polymer material improves its durability against damage from bending or stretching compared to existing materials used for making threads that were previously available beforehand. It also increases their flexibility without losing much weight due to increased tension between layers when bent together. Its technical benefits include longer lifespan, better performance under extreme conditions such as sunlight exposure, moist environments, and strong chemicals like solvents.

Problems solved by technology

The technical problem addressed by this patented technology relates to traditional thermoset materials that have poor mechanical properties such as high stress or strain under repeated usage due to their lacking flexibility at room temperatures. This can lead to failure over time with reduced performance capabilities for certain applications where they are used.

Abstract

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.
