Problems solved by technology

The traditional adhesive uses natural rubber as the raw material, and the solvent used usually contains formaldehyde, which is costly and highly toxic; later, polystyrene resin or phenolic resin is used as the main raw material, and the solution contains toluene, which still does not reduce the cost and has Toxicity; other adhesives use neoprene, in addition to the high cost, the preparation conditions also have corresponding requirements, not economical and practical
[0005] In addition to the above-mentioned glue products, there is also a cement-based product adhesive, which is a reactive polymer cement-based material, and is also a new type of adhesive studied by the present invention. The adhesive force of this adhesive Usually at 0.5MPa, the raw materials can be used after stirring and mixing at normal temperature. For example, the Chinese patent application with application number 200310107948 uses fly ash as the main raw material. Although the cost is reduced, the corresponding adhesive force is also reduced. There are still hidden dangers

Abstract

The invention discloses an adhesive special for vitrified tiles, and is characterized in that the adhesive is formed by stirring and mixing a powder material formula and a liquid material formula with a weight ratio of 5:1, wherein the powder material formula mainly comprises, on a weight basis, 300-400 parts of cement, 600-800 parts of yellow sand, 20-30 parts of fly ash, 1-2 parts of cellulose, 1-2 parts of calcium lignosulphonate, 1 part of modified polyoxyethylene; the liquid material formula mainly comprises, on a weight basis, 300-320 parts of styrene-acrylic emulsion, 30-50 parts of emulsion 601, and 600-650 parts of water; the invention adopts the polymer liquid material formula added with the powder material formula, and the two are combined both physically and chemically; the bearing capacity of the adhesive is increased, and thus the interface toughness and fracture energy are increased; an adhesive force which can not be achieved by traditional cement mortar is obtained; and the invention has high vitrified tile adhesive strength.

Description

technical field [0001] The invention relates to an adhesive for vitrified tiles, which belongs to the technical field of chemical compositions and building materials, in particular to a special adhesive for vitrified tiles. Background technique [0002] Vitrified brick is a ceramic wall tile with a smooth surface and a water absorption rate of less than 5%. It can express a luxurious and atmospheric design in the interior decoration. It is clean and tidy. It is the preferred wall surface for the existing interior decoration. brick. [0003] The choice of adhesive is the key factor for vitrified tiles used in interior decoration. Due to the smooth surface of vitrified tiles, if the adhesive effect is not good, it will affect the overall flatness and produce irregular reflections. Existing adhesives cannot ensure resistance to vibration and temperature changes after being bonded to vitrified tiles. After a period of time (usually a winter and summer alternation), there will b...
