Description

technical field [0001] The invention relates to the technical field of chlorinated polyvinyl chloride composite materials, in particular to a high-tough, heat-resistant and aging-resistant alloy material based on chlorinated polyvinyl chloride and a preparation method thereof. Background technique [0002] Chlorinated polyvinyl chloride resin (abbreviation: CPVC) is obtained by chlorination modification of polyvinyl chloride resin (abbreviation: PVC), and the chlorine content is generally 61% to 73%. Therefore, its physical and mechanical properties, especially weather resistance, corrosion resistance, aging resistance, solubility, flame retardant and self-extinguishing properties, are greatly improved compared with PVC, and it is a new type of material with excellent performance; its main application It can be used for surface coating and adhesives, and can also be used for solution spinning, etc. These applications still exist in some fields. In recent years, pipes made o...
