Problems solved by technology

[0004] The technical problem to be solved in the present invention is that the traditional water glass adhesive has the property of natural alkali return due to the high alkalinity environment of the system itself and the existence of high-concentration Na ions, and the weather resistance is poor. After using for a period of time, the mechanical strength of the material will be greatly lost. In order to solve the above problems, the invention provides a multi-metal phosphate adhesive and its preparation method

Abstract

The invention discloses a multi-metal phosphate adhesive. The multi-metal phosphate adhesive is prepared from raw materials in parts by weight as follows: 40-60 parts of multi-metal phosphate colloid, 40-60 parts of deionized water, 1-2 parts of an organosilicone water repellent, 2-3 parts of a polymer emulsion and 2-5 parts of inorganic filler powder. Compared with the prior art, the invention provides a method for preparing the multi-metal phosphate colloid from phosphoric acid and multi-metal oxide / hydroxide through a reaction, the colloid is taken as a base, and the multi-metal phosphate adhesive is prepared by blending the colloid with the organosilicone water repellent, the polymer emulsion and the inorganic active filler powder in different proportions. A system is acidic and the solubility of hydroxide corresponding to metal cations in water is lower, so that the adhesive can effectively cut off an alkali efflorescence path, and the problem of alkali efflorescence is solved in an application process of boards.

Description

technical field [0001] The invention belongs to the technical field of adhesives, and in particular relates to a polymetallic phosphate adhesive and a preparation method thereof. Background technique [0002] Traditionally, the perlite insulation board prepared by using water glass as a binder has become a popular product to replace organic insulation boards due to its low cost, simple production process, good insulation effect, and unique fire insulation properties. Recently, a large number of related reports on water glass as the main adhesive and the improvement of the adhesive system have appeared, but because water glass itself has a high concentration of Na ions, the high concentration of Na ions will cause adhesion. The Si-O-Si bond appears reversible degradation. Accompanied by this reversible degradation process, two extremely serious consequences are inevitable in the actual engineering application process: 1. The weather resistance is poor, and the mechanical str...
