Problems solved by technology

When these waste materials are recycled and reused as ceramic raw materials, it is easy to cause serious foaming and deformation of ceramic tiles during the firing process, which makes the production process difficult to stabilize and the products are unqualified
Such a large amount of ceramic polishing waste is disposed of through simple landfill, which occupies a large amount of land and pollutes water, air and soil environments

Embodiment 1

[0029] A ceramic tile jointing agent, its raw materials and parts by weight are as follows: 60 parts of cement, 50 parts of aggregate, 7 parts of expansion agent, 5 parts of water reducing agent, 6 parts of water retaining agent, 22 parts of redispersible latex powder, water-repellent 4 parts of agent, 2 parts of antibacterial agent, 3 parts of defoamer.

[0030] The cement is commercially available 42.5 grade ordinary Portland cement.

[0031] Aggregate is fly ash and tile polishing slag. Adding aggregate can not only fill the pores in the jointing agent and improve the pore structure, but also has a certain strengthening effect, increasing the number of beneficial hydration products, thereby improving the jointing agent. Strength and compactness, reduce the shrinkage and cracking of the jointing agent, and can make the jointing agent have good leveling property when it is mixed with water for joint filling.

[0032] The expansion agent is a calcium oxide-calcium sulfoalumin...

Embodiment 2

[0045] A ceramic tile grouting agent, its raw materials and parts by weight are as follows: 65 parts of cement, 55 parts of aggregate, 8 parts of expansion agent, 6 parts of water-reducing agent, 7 parts of water-retaining agent, 25 parts of redispersible latex powder, water-repellent 5 parts of agent, 3 parts of antibacterial agent, 4 parts of defoamer.

[0046] The cement is commercially available 42.5 grade ordinary Portland cement.

[0047] Aggregate is fly ash and tile polishing waste.

[0048] The expansion agent is calcium oxide-calcium sulfoaluminate composite expansion agent.

[0049] The water reducer is a naphthalene-based high-efficiency water reducer.

[0050] The water retaining agent is modified carboxypropyl methyl cellulose ether, and the viscosity of carboxypropyl methyl cellulose ether is 130,000 mPa·s.

[0051] The redispersible latex powder is styrene-acrylic latex powder, and its fineness is 190 mesh.

[0052] The water repellent is SHP-50 polysiloxan...

Embodiment 3

[0061] A ceramic tile jointing agent, its raw materials and their parts by weight are as follows: 70 parts of cement, 60 parts of aggregate, 9 parts of expansion agent, 7 parts of water-reducing agent, 8 parts of water-retaining agent, 30 parts of redispersible latex powder, water-repellent 6 parts of agent, 4 parts of antibacterial agent, 5 parts of defoamer.

[0062] The cement is commercially available 42.5 grade ordinary Portland cement.

[0063] Aggregate is fly ash and tile polishing waste.

[0064] The expansion agent is calcium oxide-calcium sulfoaluminate composite expansion agent.

[0065] The water reducer is a naphthalene-based high-efficiency water reducer.

[0066] The water retaining agent is modified carboxypropyl methyl cellulose ether, and the viscosity of carboxypropyl methyl cellulose ether is 140,000 mPa·s.

[0067] The redispersible latex powder is styrene-acrylic latex powder, and its fineness is 210 mesh.

[0068] The water repellent is SHP-50 polysil...

Abstract

The invention discloses a tile crack sealer and a preparation method thereof. The tile crack sealer comprises the following raw materials: cement, aggregates, a swelling agent, a water-reducing agent,a water-retaining agent, redispersable latex powder, a hydrophober, an antibacterial agent and a defoaming agent, and the antibacterial agent is chitosan-polyacrylic acid composite nano particles. The preparation method of the tile crack sealer comprises the following steps: drying tile polishing waste residues, and mixing the tile polishing waste residues with flyash to obtain aggregates; modifying carboxypropyl methyl cellulose ether through glyoxal to obtain the water-retaining agent; dissolving chitosan and acrylic acid in water, adding potassium persulfate and dextran, and drying to obtain the antibacterial agent; and stirring and mixing the various raw material components to obtain the crack sealer. The prepared crack sealer has the advantages of high caking property, shrinking resistance, high dispersity, good peaceability, corrosion prevention and insect repelling, the tensile strength is high, the service life is long, and burdening and construction operation are simple; andthe preparation method is high in operability and high in repeatability, the process and equipment are simple, less materials are taken, the cost is low, the efficiency is high, and the tile crack sealer is convenient to popularize.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a tile grouting agent and a preparation method thereof. technical background [0002] Tile pointing agent, also known as surface tile pointing agent, is compounded by cement, quartz sand, pigment and various additives. It is a joint material used to fill the gap between tiles or stones, and it can be used with decorative materials such as tiles and stones. Cooperate to provide a beautiful finish, and ensure the bonding and anti-seepage between the facing bricks. With the development of the building materials industry, pointing agents are widely used in the gap decoration of ceramic tiles, stone, wood, glass, aluminum-plastic panels and other materials. be usable. In addition to the decorative effect, the jointing agent also has the effects of waterproof, anti-seepage and anti-fouling, etc., which makes the decoration more perfect, safe, fast in construction, and saves material...
