초록

To a hydraulic composition for extrusion molding comprising a hydraulic substance, organic reinforcing fibers, and a thickening process aid, a defoamer containing a polyether component is added for preventing the composition from spring-back and imparting improved strength properties thereto.

대표청구항 ▼

1. A hydraulic composition for extrusion molding comprising:a hydraulic substance,organic reinforcing fibers,a thickening process aid which comprises a water-soluble cellulose ether having a viscosity of about 100 to 50,000 mPa·s when in a 1 weight % aqueous solution at 20° C., anda defoamer containing a polyether component. 2. The hydraulic composition of claim 1 wherein the defoamer containing a polyether component is provided in an amount of 0.001 to 2% by weight of the entire composition excluding water. 3. A product obtained by hardening the hydraulic composition of claim 1, wherein the organic reinforcing fibers are pulp fibers. 4. The hydraulic composition of claim 1, wherein the hydraulic substance is a cement or gypsum substance. 5. The hydraulic composition of claim 3, wherein the pulp fibers have an average fiber length of at least 700 μm. 6. The hydraulic composition of claim 1, wherein the organic reinforcing fibers are provided in an amount of 0.1 to 50 parts by weight per 100 parts by weight of the hydraulic substance. 7. The hydraulic composition of claim 1, wherein the water-soluble cellulose ether of the thickening process aid is selected from the group consisting of hydroxyalkyl alkyl celluloses, alkyl celluloses and hydroxyalkyl celluloses. 8. The hydraulic composition of claim 1, wherein the thickening process aid has a viscosity of 5,000 to 50,000 mPa·s when in a 1 weight % aqueous solution at 20°C. 9. The hydraulic composition of claim 1, wherein the thickening process aid is provided in an amount of 0.3 to 2.0% by weight of the entire composition excluding water. 10. The hydraulic composition of claim 1, wherein the thickening process aid is provided in an amount of 0.5 to 1.5% by weight of the entire composition excluding water. 11. The hydraulic composition of claim 1, wherein the composition further comprises an aggregate. 12. The hydraulic composition of claim 1 wherein the defoamer containing a polyether component is provided in an amount of 0.005 to 1.0% by weight of the entire composition excluding water. 13. The hydraulic composition of claim 1 wherein the composition is free of asbestos fibers.
