ある。In the production of such cement extrusion molded products, the extrusion pressure of the extruder is high, so cement and inorganic fibrous material are added and mixed in a kneader or the like to form a uniform cement-mixed product, which is then extruded. Dehydration occurs during extrusion molding using a machine. For this reason, water-soluble cellulose needles such as methylcellulose, methylhydroxypropylcellulose, methylhydroxyethylcellulose, hydroxyethylcellulose, and hydroxyglopylcellulose, as well as ethylene oxide polymers and acrylamide, are used as admixtures for cement extrusion products. The use of water-soluble polymers such as polymers and polyvinyl alcohol is well known as described in Japanese Patent Publication No. 53-32368. However, in recent years, CJI in cement extrusion molded products, Demand for f'1: performance such as sound insulation, fire resistance, and durability has improved, and molded products with complex shapes are increasing. In extrusion molded products with such complicated shapes, extremely high shearing forces are applied during extrusion molding, and this external frictional heat causes the temperature II of the cement mixture to rise, reaching 50 to 9 in the U season.
Reach 0U. In cement extrusion molding at such high temperatures, among the above-mentioned γ# and No. 11 agents for cement extrusion molded products, methylcellulose, methidi and hydroxyethylcellulose, methylhydrogyciglobil cellulose, and hydroxyethyl cellulose, which have gelling points, are used. Admixtures such as cellulose (c) gelatinize at high temperatures of 50 to 90C, so their function as an admixture for cement extrusion molded products is extremely poor! 'F t, , the dehydration prevention function of the cement-mixed product is lost and the extrusion pressure is f! The problem is that the surface smoothness of the extrusion molded product becomes poor due to the sharp increase in the temperature, and cracks occur, making it impossible to obtain a normal molded product.
Although hydroxyethyl cellulose alone does not cause gelation when extruded at high temperatures, it lacks dispersion power for cement, and the adhesive strength of the cement mixture is insufficient, making extrusion work difficult. It has the disadvantage of being poor. In addition, water-soluble polymers such as ethylene oxide polymer, acrylamide polymer, and polyvinyl alcohol do not gel at high temperatures, but their dehydration prevention function is poor, so they need to be used in large amounts. Compound 11 for cement extrusion molded products at high temperatures
At present, the most suitable agent has not yet been found.

By using an admixture for cement extrusion molded products made by mixing 60 to 90 parts by weight of hydroxyethyl cellulose (parts by weight, same hereinafter) and 40 to 10 parts of sodium caseinate, gelation does not occur even during extrusion molding at high temperatures. , and good extrusion molding is possible with a small amount of additive groups; hl
), and furthermore, it was discovered that it was possible to obtain an extruded acid JET product that exhibited beautiful surface smoothness due to the superior adhesive strength of the cement-containing product compared to hydroxyethyl cellulose alone, and the present invention was developed. It was completed.
