Iridescent joint filling plaster

Abstract

The invention relates to iridescent joint filling plaster.The iridescent joint filling plaster for ceramic tiles at least comprises, by weight, 650-800 parts of transparent filler, 0-400 parts of filler, 2.0-25 parts of iridescent pigments, 1.5-3 parts of cellulose ether, 0.5-5 parts of water, 200-350 parts of aqueous polymer emulsion, 2-5 parts of defoaming agents, 3-10 parts of coalescing agents, 1-3 parts of preservatives and 3-10 parts of thickening agents.The iridescent joint filling plaster, a paste, can be used instantly when a barrel is opened on a construction site, so that the problem that joints are not filled with due to inappropriate water addition quantity is avoided; unused joint filling plaster can be sealed for storage and used for next time, so that waste is avoided and the problem of later whiskering is avoided; different colors of light-sensitive or temperature-sensitive pigments can be added into the iridescent joint filling plaster according needs of clients or match with the ceramic tiles, the iridescent joint filling plaster can show different colors under ultraviolet irradiation or temperature change, and accordingly decorative effects are improved.

Description

technical field [0001] The invention relates to a seam filling paste, in particular to a magic color seam filling paste. Background technique [0002] Ceramic tiles and the cement mortar for pasting tiles will have a certain degree of flexibility, so a certain gap should be left when laying tiles. If there are no gaps, it will cause the tiles to bulge or crack during later use. Traditional tile grouts are powders made of white cement as the main ingredient, which are mixed with water on site to form a paste. This type of cement-based grout has the following problems: First, if the grout that has been mixed is not used completely Will harden and fail, resulting in wasted caulk. Second, it has high rigidity and large shrinkage coefficient, which is prone to cracking, falling off and other undesirable phenomena. The third is that the impermeability is poor. Water will seep in to form soluble salts, and flow out with rainwater, forming white spots on the surface. This is the p...

Problems solved by technology

[0002] Ceramic tiles and the cement mortar for pasting tiles will have a certain degree of flexibility, so there must be a certain gap when laying tiles. If there are no gaps, it will cause the tiles to bulge or crack during later use.

Traditional tile grouts are powders made of white cement as the main ingredient, which are mixed with water on site to form a paste. This type of cement-based grout has the following problems: First, if the grout that has been mixed is not used completely Will harden and fail, resulting in wasted caulk

Second, the rigidity is large, the shrinkage coefficient is large, and it is prone to cracking, falling off and other undesirable phenomena.

The third is poor impermeability, water will seep in to form soluble salts, and flow out with rainwater, forming white spots on the surface, which is the phenomenon of efflorescence, which affects the appearance

Fourth, the cement hydration product is strongly alkaline, which is not suitable for caulking of decorative materials such as glass mosaics, because the color layer of the mosaic material and the glass layer are connected by glue, and it is easy to oxidize once encountering acid and alkali substances. become black, thus losing the decorative effect
