Sodium silicate (water glass) is an inorganic material that is noncombustible and has excellent heat resistance, and is suitable for use in corrugated cardboard, abrasive materials, and porous adherends that are considered heat and fire resistant. Also, it is widely used as an adhesive for asbestos and paper/metal systems, but it has problems with water resistance due to its NaO content, and it also requires heating and drying to elute the basic component by adding acid. , there are some difficulties in its usage, and Z
It is known to use metal oxides such as n, AI, Mg or Ca as additives. (“Adhesives and Adhesives” written by Kanamaru Kyo, published by Dainippon Tosho Co., Ltd.) In addition, condensed zinc phosphate and aluminum were used to promote the hardening of water glass as a non-flammable binder and to improve its water resistance and workability. Alternatively, it has also been proposed to use silicon oxides or hydroxides as additives for water glass. (Japanese Patent Publication No. 50-20095) The present inventor blended a large amount of gold oxide powder into water glass with the intention of curing water glass at room temperature and improving the water resistance of the adhesive surface. We conducted adhesion tests and confirmed that silica sand powder and aluminum hydroxide powder have an effect on the room-temperature curing and water resistance of water glass. fffJ II
It has been found that when an emulsion or a cationic oligostyrene-butadiene rubber latex is mixed with water glass, the water resistance of water glass neck cutting is greatly improved. It was also found that mixing alkali-modified or cation-modified emulsicone with silica sand and water glass significantly improves the water resistance of the water glass adhesive, and that crushing silica sand in the presence of water significantly improves the water resistance of the water glass adhesive. fSHf Then,
The prefecture has also found that the water resistance of hydraulic lath adhesives has been significantly improved, and based on these findings, the present invention has been developed.
