Abstract

The invention relates to an application of scrap tire rubber powder and scrap polystyrene (PS) foam to production of PVC (polyvinyl chloride) or vinylidene chloride or CPVC (chlorinated polyvinyl chloride) laminates or other sections and appliances. Plenty of cheap black pollutants-scrap tire rubber powder and white pollutants-scrap PS foam are simultaneously adopted as the main modifiers, thus the processability can be improved, the impact strength can be improved and the released hydrogen chloride can be simultaneously absorbed, and the scrap tire rubber powder and the scrap PS foam are matched with defined amount of zinc oleate and barium oleate thermal lubricating stabilizers which can absorb hydrogen chloride and conventional processing aids to produce the CPVC and PVC materials with low prices and excellent properties through the production processes such as preheating, mixing, laminating and the like or produce such sections as bars, sheets, pipes and the like or plastic appliances by adopting plastic extruders and plastic injection moulding machines.

Description

technical field [0001] This scheme belongs to the invention patent and relates to polymer materials, specifically a modification method of chlorinated polyvinyl chloride (CPVC) and polyvinyl chloride. Background technique [0002] Chlorinated polyvinyl chloride or perchlorinated vinyl resin (CPVC) and polyvinyl chloride resin (PVC) have excellent heat resistance, mechanical properties and corrosion resistance, but industrially supplied CPVC and PVC are fluffy powder or granular . In application, processing aids such as stabilizers, plasticizers, and modifiers can be added, extruded pipes and plates through extruders, or injection molded into mechanical parts through injection molding machines, and can also be made by adding organic solvents, pigments and fillers, etc. Anti-corrosion coatings, especially CPVC, have high chlorine content, and hydrogen chloride gas is easily decomposed during processing, but hydrogen chloride gas can catalyze the decomposition of CPVC (or PVC)...
