Soft poly vinyl chloride resin type waterproof shi - to

摘要

PURPOSE: To provide a resin water-proof sheet good in the flexibility, opacifying property and weather resistance and useful as a water-proof sheet for roofs, etc., by adding a plasticizer, glycine zinc salt, an organic phosphate ester and chlorination method titanium dioxide to a polyvinyl chloride resin. ;CONSTITUTION: 100 pts.wt. of a polyvinyl chloride resin, 40-80 pts.wt. of a plasticizer such as dioctyl phthalate, 0.1-5.0 pts.wt. of glycine zinc salt as a stabilizer, 1.0-10.0 pts.wt. of an organic phosphate ester as a stabilization auxiliary, and 3.0-15.0 pts.wt. of chlorination method titanium dioxide as a filler are dry- blended with each other by the use of a Henschel mixer, etc., and subsequently molded by a conventional extrusion method into the objective soft polyvinyl chloride resin waterproof sheet added in the flexibility, good in the opacifying property, sheeting property, and weather resistance, not deteriorating its softness over a long period, reduced in the lowering of the mechanical strength, and free from the generation of sags, creases and cracks.;COPYRIGHT: (C)1993,JPO&Japio
