Problems solved by technology
[0004] In the adhesive raw materials in the prior art, it is often necessary to add solvents or film-forming aids to improve the compatibility and mixing effect of the raw materials, but solvents or film-forming aids are generally organic solvents that cause serious pollution to the air. There is a great health hazard to the health of the body after the back glue is applied to the tile decoration

preparation example Construction
[0044] The preparation method of two-component water-based environment-friendly tile back glue of the present invention comprises the following steps:
[0045] 1) Using alkylmethacrylate monomers, functional monomers, initiators, and composite emulsifiers as raw materials, and reacting with water as a medium to prepare acrylate emulsions;
[0046] 2) taking vinyl acetate, acrylate, acrylic acid, initiator, and emulsifier as raw materials, and reacting after dissolving in water as a medium to prepare vinyl acetate-acrylate copolymer emulsion;
[0047] 3) In parts by weight, take 30-50 parts of acrylate emulsion and 40-60 parts of vinyl acetate-acrylate copolymer emulsion, and mix them uniformly to obtain the two-component water-based environment-friendly tile back adhesive.
Embodiment 1
[0050] The two-component water-based environment-friendly tile adhesive of the present embodiment comprises the following components in parts by weight:
[0052] 60 parts of vinyl acetate-acrylate copolymer emulsion,
[0053] Wherein, by weight, the acrylate emulsion includes the following components:
[0054]
[0055]
[0056] In parts by weight, the vinyl acetate-acrylate copolymer emulsion comprises the following components:
[0057]
[0058]The bonding strength of the two-component water-based environment-friendly tile back adhesive prepared in this example is 1.3 MPa, and it dries and solidifies within 1 hour, and has good environmental friendliness.
Embodiment 2
[0060] The two-component water-based environment-friendly tile adhesive of the present embodiment comprises the following components in parts by weight:
[0062] 45 parts of vinyl acetate-acrylate copolymer emulsion,
[0063] Wherein, by weight, the acrylate emulsion includes the following components:

Abstract
The invention provides a preparation method for a two-component water-based environmentally-friendly ceramic tile back adhesive. The preparation method comprises the following steps: 1) an alkylmethacrylatemonomer, a functional monomer, an initiator and a composite emulsifier are used as raw materials, water is used as a medium, and after dissolving is performed, a reaction is performed to prepare an acrylateemulsion; 2) vinyl acetate, acrylate, acrylic acid, an initiator and an emulsifier are used as raw materials, water is used as a medium, and after dissolving is performed, a reaction isperformed to prepare a vinyl acetate-acrylatecopolymeremulsion; and 3) 30-50 parts by weight of the acrylate emulsion and 40-60 parts by weight of the vinyl acetate-acrylate copolymer emulsion aretaken, uniform mixing is performed, and therefore the two-component water-based environmentally-friendly ceramic tile back adhesive is obtained. The preparation method for the two-component water-based environmentally-friendly ceramic tile back adhesive provided by the invention is simple and convenient, and the prepared two-component water-based environmentally-friendly tile back adhesive has environmental friendliness on the basis of ensuring good adhesive performance.
Description
technical field [0001] The invention belongs to the technical field of tile back glue, and relates to a preparation method of a two-component water-based environment-friendly tile back glue. Background technique [0002] During the pasting process of tiles, due to the influence of construction conditions, ambient temperature, bonding materials, especially the density and water absorption of tiles, they often fall off; tile adhesive is specially used for the back treatment of wet tiles, and is also suitable It is suitable for stone materials with low water absorption, dense texture and smooth surface, which can effectively improve the bonding strength between ceramic tiles and bonding materials, and solve common problems such as hollowing and falling off in tile wet paste. [0003] CN105969308A discloses an eco-friendly tile adhesive for vitrified tiles. The eco-friendly tile adhesive for vitrified tiles of the invention comprises the following components: 20% to 40% of micro...
