Elastic waterproof binder additive and preparation method thereof

Abstract

The invention relates to an elastic waterproof binder additive and a preparation method thereof. The product is an elastic waterproof binder additive with improved performances and prepared by stirring and mixing three components, and the preparation method comprises the following steps of: respectively stirring, mixing, filtering and packaging. The elastic waterproof binder additive disclosed by the invention has the advantages that the additive is soft inside despite its hard shell, stable in hue, moderate in consistency, good in acid resistance and alkaline resistance, and easy to control, and the like; while the elastic waterproof binder additive is used for preparing an elastic cement-base waterproof binder, the elastic waterproof binder additive also has the characteristics that after the elastic waterproof binder additive is mixed with cement powder, the obtained product is stable in hue, the binding strength of the obtained product exceeds the requirements of national standards, and the obtained product is good in acid resistance and alkaline resistance, not bloated, not thickened, long in applicable time, good in construction operating degree, not flowing, strong in flow resistance, stable in product quality, low in cost, and the like; and the elastic waterproof binder additive is applied to the ceramic tile binding of exterior wall marbles, thin porcelain plates and ceramic tiles under high-strength freezing-thawing-resisting alternated bad temperature conditions.

Description

technical field [0001] The invention relates to the technical field of chemical building materials, in particular to an elastic waterproof adhesive additive and a preparation method thereof. The product is suitable for preparing cement-based elastic high-strength waterproof adhesives, high-strength interface agents and the like. Background technique [0002] There are no high-strength waterproof elastic adhesive additives currently on the market. It makes up for the additives currently on the market that are only used to bond ceramic tiles and have no waterproof performance. Singapore Quick Seal Building Materials Pte Ltd. QS604. This modified emulsion additive is only used as a binding agent after being mixed with cement, and it does not have waterproof performance. The bonding strength of the cement-based surface is less than 1.5Mpa, and the shear strength cannot meet the requirements of the national standard at the same time; the second is that the cement-based adhesive p...

AI Technical Summary

Problems solved by technology

This modified emulsion additive is only used as a binding agent after being mixed with cement, and it does not have waterproof performance. The bonding strength of the cement-based surface is less than 1.5Mpa, and the shear strength cannot meet the requirements of the national standard at the same time; the second is that the cement-based adhesive prepared with the quick-sealing adhesive additive emulsion is easy to chemically react with the alkaline substances in the cement. Unstable, swollen, and thickened, resulting in short construction time and difficult construction operations; the third is that the cement-based adhesive prepared with quick-sealing adhesive additive emulsion is easy to change green phase, blue phase, black phase, swelling , thickening, short usable time, poor construction performance
