Abstract

The invention discloses a chlorinated polyvinyl chloride waterproof coiled material and a preparation method thereof. The material is composed of a base material of chlorinated polyvinyl chloride, and added materials of a plasticizing agent, a toughening agent, a filling agent, and other additives. An extrusion calendar molding method is adopted, and the chlorinated polyvinyl chloride waterproof coiled material is produced. The chlorinated polyvinyl chloride waterproof coiled material provided by the invention has various excellent comprehensive economic and technical performance indicators such as excellent water resistance, excellent flame retardance, anti-leakage performance, weatherability, high tensile strength, high elongation, aging resistance, high deformation adaptability, wide temperature adaptation range, high adhesive strength, long service life, easy construction, low cost, and the like. The material can be used in waterproofing works of architectural roofing, bridge deck concrete, subways, and roads.

Description

technical field [0001] The invention belongs to the field of waterproof material preparation, and in particular relates to a chlorinated polyvinyl chloride waterproof coiled material and a preparation method thereof. Background technique [0002] Chlorinated polyvinyl chloride, referred to as CPVC, is obtained by chlorination and modification of polyvinyl chloride (PVC) resin. The product is white or light yellow tasteless, odorless, non-toxic loose particles or powder. After the PVC resin is chlorinated, the irregularity of the molecular chain arrangement increases and the polarity increases, which increases the solubility and chemical stability of the resin, thereby improving the heat resistance of the material and resistance to acids, alkalis, salts, oxidants, etc. corrosion performance. Improve the mechanical properties of the heat distortion temperature of the resin, the chlorine content increased from 56.7% to 63-69%, the Vicat softening temperature increased from 72-...
