Description
【発明の詳細な説明】 ［産業上の利用分野］ 本発明はセメント系押出成形用添加剤に関する。[Detailed description of the invention] [Industrial application field] The present invention relates to additives for cementitious extrusion molding.
［従来の技術］
セメント質を主成分とする水混練物、たとえば石綿・セ

イスにがかる押出圧力により水混練物の保水性が悪いた
め、水が分離してダイス出口より水のみが出て、固形物
が押出成形機に詰まる脱水現象が起ることである。[Prior Art] A particular problem when extruding a water-kneaded product containing cement as a main component, for example, a water-kneaded product of asbestos and cement, is that the extrusion pressure applied to the die causes poor water retention of the water-kneaded product. Water separates and only water comes out from the die outlet, causing solid matter to clog the extruder, resulting in a dehydration phenomenon.
従来この脱水現象を防止するために、セルロース誘導体
、ポリビニルアルコール、ポリエチレンオキサイド、ポ
リアクリルアミド等のハイドロ変型剤が知られている（
たとえば特公昭４３−７１３４号公報）。Conventionally, hydro-transforming agents such as cellulose derivatives, polyvinyl alcohol, polyethylene oxide, and polyacrylamide have been known to prevent this dehydration phenomenon (
For example, Japanese Patent Publication No. 43-7134).
［発明が解決しようとする問題点］
しかし上記ハイドロ変型剤を使用しても押出成形工程に
おいてセメント系を主成分とする水混練物の脱水現象が
起こる場合や、押出成形機のスクリューのトルクが大き
くなるという問題点があった。[Problems to be solved by the invention] However, even if the above-mentioned hydro-transforming agent is used, dehydration of the water-kneaded product mainly composed of cement may occur during the extrusion molding process, or the torque of the screw of the extruder may be reduced. There was a problem with the size.
［発明を解決するための手段］

発明に到達した。[Means for Solving the Invention] The present inventors have arrived at the present invention as a result of extensive studies aimed at obtaining an extrusion molding additive that does not cause dehydration and has low torque.
