Problems solved by technology

[0003] At present, there are mainly two types of wall joint filling materials on the market: (1) One is the ceramic tile color grouting agent that is mainly applied by plastering: inorganic materials, mainly by plastering, and the construction process is relatively complicated
(2) The other is the polymer color beautifying agent for extrusion coating: it is composed of high-tech new polymers and high-grade pigments. The construction process is simple, but the price is expensive, and it is rarely available
However, this resin-based caulking agent is mainly designed for the gaps of indoor tiles, and its adhesion strength to old concrete is poor, and after a long time of use, the color will become dull and dull, thus losing the decorative effect

preparation example Construction

[0031] The preparation method of branched curing agent described in the present invention is as follows:

[0032] In a 500 ml four-neck round bottom flask equipped with a mechanical stirrer, a thermocouple temperature controller, a condenser, and nitrogen protection, add 121.7 g of polyether diol, heat to 110° C., and vacuumize to remove moisture. Under mechanical stirring, 40.4 grams of methylhexahydrophthalic anhydride were added. Stirring was continued, the reaction temperature was maintained at 110° C., and the reaction was carried out for 6 hours. The molecular weight of the polyether diol is 1000 g / mol.

[0033] The two-component water-based epoxy colored sand caulking agent described in the present invention is mixed with epoxy resin curing agent and branched curing agent in a certain proportion. It is found that the curing speed is fast, and it will not collapse or sag after curing. And it can penetrate into the hollow part of the ceramic tile to carry out deep caulk...

Description

technical field [0001] The invention relates to the field of caulking agents, and more particularly to a two-component water-based epoxy colored sand caulking agent and its use and preparation methods. Background technique [0002] In modern buildings, tiles have become the main building materials and are widely used in the decoration of the interior and exterior walls and floors of buildings. In order to avoid hollowing between tiles due to thermal expansion and contraction, there must Leave a gap that needs to be filled with tile grout. The tile grout should have an expansion coefficient close to that of the tiles and a certain degree of flexibility, which can expand and contract with the tiles to avoid cracks. The main components of tile grout are cementitious materials, fillers and additives. The cementitious materials endow the grout with adhesion, the additives endow the grout with good workability, flexibility and other functions, and the fillers have an effect on th...
