In a stabilized polyvinyl chloride molding mixture containing a stabilizer combination based upon alkali metal, alkaline earth metal, and/or zinc soaps, co-stabilizers, powdered, crystalline, hydrous aluminosilicate, and flow promoters, as well as optionally additional conventional additives, the improvement which comprises, per 100 parts by weight of polyvinyl chloride,(a) from about 0.2 to 5 parts by weight of a synthetic, crystalline, powdered alkali metal aluminosilicate containing from about 13 to 25 percent by weight of water of crystallization; and(b) from about 0.1 to 5 parts by weight of at least one co-stabilizer selected from the group consisting of .beta.-diketones, .alpha.-ketoenol esters, .alpha.-acyllactones, substituted 1,4-dihydropyridine-3,5-dicarboxylic acids, and pyrrole, the pyrrole being unsubstituted or substituted.
摘要:
This invention is directed to water-dilutable alkyd and acrylate resins. More particularly, this invention is directed to a method for the preparation of water-dilutable resin preparations based upon alkyd and acrylate resins which comprises the steps of:(a) preparing an aqueous alkyd resin dispersion, wherein the alkyd resin has an acid number of from about 5 to 40 and a hydroxyl number of from about 150 to 300 and the dispersion has a solids content of from about 30 to 90 percent by weight; and(b) polymerizing monomers of acrylic acid derivatives or methacrylic acid derivatives in the dispersion from step (a), optionally in the presence of additional water, to obtain a total solids content of from about 30 to 80 percent by weight, the weight ratio of alkyd resin to acrylate resin being from about 1:4 to 9:1.This invention is also directed to the use of these binders in water-dilutable lacquer systems.
