Impact-resistant cold-resistant polyvinyl chloride wire tube and preparation method thereof

PendingCN122356677AElastomerFiber
This invention discloses a method for preparing impact-resistant and cold-resistant polyvinyl chloride (PVC) conduit, belonging to the field of PVC material technology. In this invention, butyl rubber is complexed with dioctyl sebacate and active silica under the initiation of tert-butyl hydrogen peroxide. This complex acts as a flexible dispersed phase in the PVC matrix, effectively absorbing and dissipating impact energy and lowering the glass transition temperature of the material. This allows the conduit to maintain excellent toughness and crack resistance even at low temperatures. Furthermore, it works synergistically with impact modifiers in the system. Ethylene-vinyl acetate copolymer provides elastomer toughening, while maleic anhydride-styrene graft copolymer acts as a highly efficient compatibilizer and interfacial reinforcing agent. The compounded structure forms a toughening network, achieving toughening from molecular chain segment movement to microstructure, thus improving impact strength. Subsequent addition of reinforcing fibers of the same specification further enhances the strength of the conduit. Overall, this results in a PVC conduit with excellent strength, impact and cold resistance, and thermal properties.

The preparation method comprises the following steps: adding 1-butyl-3-methylimidazole acetate; cerium trifluoromethanesulfonate; dibenzoyl methane; the invention further provides a preparation method of the high-weather-resistance chlorinated polyethylene rubber and plastic material, and the preparation method comprises the following steps: firstly, preparing each stabilizer into a uniform liquid premixed master batch, and then carrying out melt blending on the liquid premixed master batch and resin, so that effective construction of a micro-reaction region is ensured. Through the synergetic stable system, intelligent response and long-acting catalysis of a stable function are realized, the problems of easy migration, non-uniform dispersion and short action period of a traditional auxiliary agent are fundamentally solved, the material is endowed with excellent long-term weather resistance and color stability, and the material is suitable for preparing products such as outdoor profiles and pipes.
