Process for preparing plastic compositions containing a silicate dispersed therein |
摘要 |
Silica plastic compositions containing a silicate filler finely dispersed therein are produced by simultaneously adding a mixture of an aqueous solution of an alkali silicate and a coagulable latex emulsion of a plastic polymeric material and a solution of at least one salt of hydrochloric or sulfuric acids and a metal selected from the group consisting of zinc, magnesium, calcium, and maintaining the pH of the reaction medium at a level appropriate for the precipitation of the neutral silicate of the metal, yet at which precipitation of either hydroxy salts of the metal or of alkaline silicates is substantially precluded.
