Problems solved by technology

[0003] As a kind of polymer-modified cement-based adhesive, tile adhesive is mainly used to paste ceramic tiles, facing tiles, floor tiles and other decorative materials. Compared with simply using cement to bond tiles, tile adhesive has high bonding strength, water resistance, freeze-thaw resistance, and good aging resistance. It is a very ideal bonding material, but at present, the tile adhesive on the market has poor quick-drying performance. , unable to meet the needs of rapid construction

Embodiment 1

[0027] A high-strength quick-drying tile adhesive, which consists of the following ingredients in parts by weight:

[0028] 90 parts of cement, 50 parts of river sand, 30 parts of fly ash, 1 part of rice bran oil, 1 part of water retaining agent, 0.1 part of early strength agent, 2 parts of polyvinyl alcohol, 20 parts of epoxidized styrene-butadiene rubber powder, styrene-butadiene emulsion 100 copies.

[0029] Among them, the water-retaining agent is a mixture of cellulose / bentonite-based superabsorbent resin and hydroxypropyl methylcellulose ether at a mass ratio of 10:1.

[0030] The preparation method of cellulose / bentonite-based superabsorbent resin is as follows:

[0031] Under ice bath, add sodium hydroxide aqueous solution with a mass concentration of 10% to acrylic acid to make the neutralization degree of acrylic acid 80%. After stirring and reacting for 20 minutes, add acrylamide (70% of the mass of acrylic acid) and bentonite, and stir After reacting for 10 minut...

[0038] A high-strength quick-drying tile adhesive, which consists of the following ingredients in parts by weight:

[0039] 90 parts of cement, 50 parts of river sand, 30 parts of fly ash, 1 part of rice bran oil, 1 part of water retaining agent, 0.1 part of early strength agent, 1 part of polyvinyl alcohol, 20 parts of epoxidized styrene-butadiene rubber powder, styrene-butadiene emulsion 100 copies.

[0040] Among them, the water-retaining agent is a mixture of cellulose / bentonite-based superabsorbent resin and hydroxypropyl methylcellulose ether at a mass ratio of 10:1.

[0041] The preparation method of cellulose / bentonite-based superabsorbent resin is as follows:

[0042] Under ice bath, add sodium hydroxide aqueous solution with a mass concentration of 10% to acrylic acid to make the neutralization degree of acrylic acid 80%. After stirring and reacting for 30 minutes, add acrylamide (70% of the mass of acrylic acid) and bentonite, and stir After reacting for 5 minutes...

Embodiment 3

[0048] A high-strength quick-drying tile adhesive, which consists of the following ingredients in parts by weight:

[0049] 80 parts of cement, 60 parts of river sand, 30 parts of fly ash, 2 parts of rice bran oil, 0.1 part of water retaining agent, 1 part of early strength agent, 1 part of polyvinyl alcohol, 25 parts of epoxidized styrene-butadiene rubber powder, styrene-butadiene emulsion 100 copies.

[0050] Among them, the water-retaining agent is a mixture of cellulose / bentonite-based superabsorbent resin and hydroxypropyl methylcellulose ether at a mass ratio of 15:1.

[0051] The preparation method of cellulose / bentonite-based superabsorbent resin is as follows:

[0052] Under ice bath, add sodium hydroxide aqueous solution with a mass concentration of 5% to acrylic acid, so that the neutralization degree of acrylic acid is 80%, and after stirring for 10 minutes, add acrylamide (70% of the mass of acrylic acid) and bentonite, and stir After reacting for 10 minutes, ad...

Abstract

The invention relates to the field of building materials, in particular to a high-strength quick-drying ceramic tile adhesive and a preparation method thereof.The high-strength quick-drying ceramic tile adhesive is prepared from cement, river sand, fly ash, rice bran oil, a water-retaining agent, an early strength agent, polyvinyl alcohol, epoxidized styrene-butadiene rubber powder and styrene-butadiene emulsion. The industry standard requires the tensile bond strength of C1 ceramic tile glue to reach 0.5mpa, the tensile adhesive strength of the C2-grade ceramic tile adhesive needs to reach 1.0 MPa, general C1-grade ceramic tile adhesive is only suitable for adhering indoor and outdoor small-specification ceramic tiles, the C2-grade ceramic tile adhesive is suitable for adhering indoor and outdoor vitrified tiles and stones, the 20min tensile adhesive strength of the prepared ceramic tile adhesive is close to 1.0 MPa, the 28d tensile adhesive strength is larger than or equal to 3.01 MPa, the water absorption rate is smaller than or equal to 0.14%, and the ceramic tile adhesive has good water resistance.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a high-strength quick-drying tile adhesive and a preparation method thereof. Background technique [0002] Compared with other wall materials and floor decoration materials, ceramic tiles have great advantages in terms of easy cleaning, convenient care and durability, and have become one of the indispensable building materials in modern buildings. [0003] As a kind of polymer-modified cement-based adhesive, tile adhesive is mainly used to paste ceramic tiles, facing tiles, floor tiles and other decorative materials. Compared with simply using cement to bond tiles, tile adhesive has high bonding strength, water resistance, freeze-thaw resistance, and good aging resistance. It is a very ideal bonding material, but at present, the tile adhesive on the market has poor quick-drying performance. , unable to meet the needs of rapid construction.
