Abstract

The invention discloses advanced waterproof adhesive. The advanced waterproof adhesive mainly comprises, by weight, 60-100 parts of waterborne polymer resin, 0-30 parts of fillers, 0.1-0.5 part of plasticizers, 0.1-1.0 part of wetting and dispersing agents, 0.1-0.5 part of thickening agents, 0.1-0.5 part of stabilizers, 0.2-0.8 part of thixotropic agents, 0.1-0.8 part of preservatives and 0.1-0.5 part of defoaming agents. The advanced waterproof adhesive has the advantages that the problems of poor water resistance and alkali resistance of ordinary adhesive adhered with bottom materials such as cement-based surfaces and ceramic tiles, deterioration of adhesive properties due to easiness in aging and the like can be solved by the aid of the selected resin with high water resistance; the fillers are selected, formulas are optimized, and accordingly the strength and the weather resistance of the advanced waterproof adhesive further can be improved; auxiliaries and the formulas are optimized, and accordingly the stability of the advanced waterproof adhesive can be improved; raw materials for the advanced waterproof adhesive are low and appropriate in cost and convenient to construct and are non-toxic and environmentally friendly, and accordingly the advanced waterproof adhesive is particularly applicable to the fields with requirements in the waterproof aspects.

Description

technical field [0001] The invention relates to the field of construction chemical materials, more specifically, to a high-grade waterproof adhesive. Background technique [0002] Binder is a material widely used in the construction and chemical industries, and it is the guarantee of the bonding strength between the abrasive and the matrix. As early as ancient times, human beings began to paste objects with dried resin. Ancient China and the Kingdom of Babylon used asphalt or kraft glue as a binder. From the Middle Ages to modern times, Europe has begun to use bone glue, casein made from milk or gum arabic as a binder. In the 20th century, humans invented "synthetic binders" made of polymer chemistry and petrochemistry. There are many kinds of "synthetic binders" with strong cohesive force, and the output has also developed by leaps and bounds. However, the adhesives currently on the market have poor waterproof performance, poor cohesive force, contain harmful substances ...
