One-component adhesive for vitrified tiles

Abstract

The invention discloses a single component vitrified brick back glue, which comprises the following components in parts by weight: 20 to 50 parts of emulsion, 5 to 25 parts of aqueous epoxy resin, 0.5 to 3 parts of sodium silicate, 0.5 to 2 parts of auxiliary agent, 0.5 to 2 parts of modifier, 50 to 70 parts of slag micro powder, 0.1 to 0.8 part of antiseptic, and 0.1 to 1 part of dispersant, wherein the emulsion comprises 15 to 35 parts of acrylic acid emulsion and 5 to 15 parts of VAE emulsion, the auxiliary agent is fumed silica, and the modifier is a silane coupling agent. The provided single component vitrified brick back glue has the advantages of good flexibility, high bonding strength, and good weatherability, the compatibility between the back glue and a cement based adhesive material is good, and the bonding requirements of vitrified bricks can be met completely. Aqueous epoxy resin has the characteristics of good adhesive force, excellent operability, good anticorrosion performance, and acid / alkali resistance. Through the back glue, vitrified bricks can be adhered on different base materials, the construction is simple, and the problems such as hollowing, bubbling, falling, and the like, in vitrified brick pasting are solved.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a single-component vitrified tile 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 absorption, edge straightness, b...

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
