Title:
POLYVINYL CHLORIDE RESIN GRANULE FOR PASTE PROCESSING AND PREPARATION THEREOF
Document Type and Number:
Japanese Patent JP3956169
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a polyvinyl chloride resin granule for a paste processing which has a small powder-adhesiveness, an excellent powder-flowability and a good dispersibilty into a plasticizer during a plastisol preparation.
SOLUTION: This resin granule is a coagulated form of polyvinyl chloride resin powders for paste processing. The granule contains less than 0.5 wt.% of the component left on the sieve in the JIS 149 μm standard sieve classification and not more than 10 wt.% of the component having not more than 10 μm in diameter. The apparent density (loose) is 0.45-0.58 g/cm3. The plastisol obtained by stirring and mixing 100 g of the resin granule and 50 g of dioctylphthalate in a cylindrical container having an inner diameter of 85 mm with a mixing blade consisting of crossed four petal-shaped flat plate blades having a blade length from the rotation axis of 35 mm, a horizontal blade width of 20 mm and a thickness of 0.7 mm, which mixing blade is located where the lower face of the blade is 5 mm above the container bottom, at 500 rpm of the rotation rate for 5 min contains less than 0.3 wt.% of the component left on the sieve in the JIS 62 μm standard sieve classification.
