Problems solved by technology

[0002] In modern life, ceramic tiles have become the main building decoration materials, and are widely used in interior and exterior walls of buildings and ground decoration. Common cement, white cement or colored cement cement mortar or clean slurry is generally used as the joint filler. This type of cement joint sealant has the following disadvantages: First, it is easy to harden, which causes great inconvenience to the construction , if the caulking agent is not fully used in a short period of time, the caulking agent will fail, often resulting in waste of the caulking agent; second, the rigidity is large, the shrinkage coefficient is large, and shrinkage cracking is extremely easy to occur after hardening. When the temperature changes, the stress changes, which is easy to cause the adhesive layer to break, peel off and other undesirable phenomena; third, the bonding performance is poor, and it is easy to crack and fall off under the action of the outside world; fourth, impermeability Poor performance, when used on the exterior wall, rainwater seeps in to form soluble salt, and flows out with the rainwater, resulting in "white pulp" phenomenon, which seriously pollutes the wall surface and affects the aesthetic appearance; fifth, it is not beautiful. There are various formats and varieties, and are favored by consumers. They also have high requirements for matching caulking materials, otherwise the expected aesthetic effect of various ceramics will not be achieved.
Later, colored cement joint fillers appeared, and colored cement joint sealants also have the above-mentioned shortcomings, and the color is relatively monotonous, and the variety is relatively single. It is still slightly inferior to various high-end mosaic products and ceramic products. Obtain the overall perfect effect, which greatly reduces the decorative effect

Abstract

The invention relates to the technical field of sealants, in particular to a crystal sealant. The crystal sealant comprises the following components by weight percent: 70-90% of crystal filler and 10-30% of waterborne resin, wherein the waterborne resin is acrylic acid-styrene polymer. The crystal sealant provided by the invention is resin type instant daub which has good construction properties and can not harden and lose efficacy in a short time; by combining an inorganic material and an organic material, when the stress changes with the temperature change, the shrinkage cracking phenomenon can not be caused easily; the crystal sealant has a good bonding property, and the waterborne resin is the acrylic acid-styrene polymer which is in a waterborne latex shape, has good bonding capability and excellent water resistance and impermeability and can form a transparent and glossy membrane; the crystal sealant is beautiful, is from transparent to semitransparent, has glassy luster and is high-grade and precious; and when the crystal sealant is matched with all kinds of delicate mosaic products, the combinations look great and the entire perfect effect can be realized.
