Environmental-friendly single-component vitrified brick gum and preparation method thereof

Abstract

The invention provides environmental-friendly single-component vitrified brick gum and a preparation method thereof. The vitrified brick gum comprises the following components in percentage by weight: 60 to 80 percent of emulsion, 10 to 20.5 percent of a waterproof agent, 7 to 13 percent of a bonding agent, 0.2 to 0.7 percent of a dispersing agent, 0.2 to 0.6 percent of an antifoaming agent, 0.3 to 0.6 percent of an anticorrosion agent, and 1.5 to 5 percent of a modifying agent. The environmental-friendly single-component vitrified brick gum can completely meet the bonding requirements of vitrified bricks, effectively solves the problems of hollowing, peeling, falling off and the like of vitrified bricks during bonding, and has the advantages of simplicity in construction, environment protection, low cost and the like. By mixing the emulsion formed by mixing water-based epoxy resin emulsion and carboxy styrene-butadiene latex, with the solid content being 50 percent or higher, with other components, the solid content of the gum reaches 50 to 55 percent, so that the increasingly strict VOC limitations are met, and the gum shows extremely high bonding powder.

Description

technical field [0001] The invention belongs to the field of building materials, in particular to an environment-friendly single-component vitrified brick adhesive. Background technique [0002] At present, ceramic bricks with high water absorption rate (5% to 10%) used in home decoration, large clubs, supermarkets and interior and exterior decoration of buildings have low strength, single style and small size, so they are no longer suitable for high-speed development. At the same time, vitrified bricks have been widely used in the architectural decoration market because of their advantages of low water absorption, high strength, specifications and varieties. [0003] Vitrified bricks are made of quartz sand and mud fired according to a certain proportion, and then polished brightly but do not need to be polished. The surface is as smooth and translucent as a glass mirror. It is superior to ordinary glazed tiles, polished tiles and general marble in terms of water absorptio...

Problems solved by technology

[0004] At present, there are many kinds of vitrified tile adhesives on the market. Some vitrified tile adhesives are composed of dry powder components and liquid components. When using, the dry powder components and liquid components are mixed according to a certain ratio for paving. On the back of ceramic tiles, vitrified tiles, floor tiles and other decorative materials, however, this two-component composition must be mixed strictly according to the ratio of dry powder and liquid parts, which has certain requirements for preparation conditions and is inconvenient to use; there are also some The vitrified tile adhesive is generally made of natural rubber and cement adhesive. The vitrified tile adhesive made of natural rubber usually contains formaldehyde, which is high in cost and high in toxicity. In addition, the preparation conditions also have corresponding requirements, which is not enough Economical and practical, vitrified tile back adhesive using cement-based adhesive is a reactive polymer cement-based material, which has the advantage of low cost, but the adhesive force is reduced, and it is prone to hollowing, resulting in rotation Shedding, especially in vibration and stable transformation, easy to peel and peel
