Background technology
At present, ceramic tile has become one of material the most frequently used in the building decoration.There is certain slit between ceramic tile and the ceramic tile, need fills with material of construction.At first, used packing material be white cement and sand by a certain percentage field mix form, but this packing material does not have performances such as waterproof, cracking resistance, cracking, dry linting often occur, thereby rainwater is easy to enter inside, causes phenomenons such as the accumulation of salt in the surface soil, ceramic tile come off through freeze-thaw cycle.At these problems that occur, domestic scholars is also studied.By analyzing, the main method of employing solves above problem by adding Vinyl Acetate Copolymer-ethene polymers powder, water-holding agent and other properties-correcting agent, for example just discloses a kind of color tile grout of knowing clearly in No. 00117192.5 Chinese invention patent application.Yet, though these methods can solve phenomenons such as the cracking, dry linting of appearance, the defective of the accumulation of salt in the surface soil to be improved not obvious, As time goes on the reason that causes owing to add hydrophober, it constantly decomposes and thinks the outside surface migration, and later stage hydrophobic effect reduces significantly.
Summary of the invention
In order to solve above-mentioned deficiency of the prior art, the invention provides a kind of color tile grout and preparation method thereof.This tile grout not only can effectively solve problems such as traditional pointing is easy to crack, water-repellancy difference, and can solve the long-term hydrophobic effect of common tile grout.
The invention provides a kind of color tile grout, it comprises following component by weight percentage:
White portland cement 35.00-50.00%;
Silica powder 45.00-60.00%;
Hydroxypropyl methyl cellulose ether 0.05-0.30%;
Ethene/vinyl laurate/vinylchlorid terpolymer rubber powder 1.50-3.00%;
Hydrophober 0.05-0.25%;
Ferric oxide series pigment 1.00-3.00%.
The preferred weight percent of described each component of spackling is respectively:
White portland cement 40.00-45.00%;
Silica powder 50.00-55.00%;
Hydroxypropyl methyl cellulose ether 0.10-0.30%;
Ethene/vinyl laurate/vinylchlorid terpolymer rubber powder 2.00-2.50%;
Hydrophober 0.10-0.20%;
Ferric oxide series pigment 2.00-2.50%.
Described color tile grout also comprises following component with weight percent:
Lignin fibre 0.15-0.30%;
Polypropylene fibre 0.01-0.05%;
Thixotropic agent 0.01-0.20%;
Water reducer 0.01-0.20%;
Described white portland cement is the white portland cement of No. 32.5 silicate cements or No. 42.5, described silica powder is 200 orders~400 order silica powders, described thixotropic agent is calcium-base bentonite thixotropic agent or sodium bentonite thixotropic agent, and described water reducer is melamine high-efficiency water-reducing agent or polycarboxylate water-reducer.
The present invention replaces common Vinyl Acetate Copolymer-ethene polymers powder by the rubber powder powder that adding has hydrophobicity performance, continue to add hydrophober simultaneously, thereby guaranteed that not only the initial stage has good hydrophobic function, and also had good hydrophobic effect for a long time.Simultaneously, color tile grout of the present invention has improved application property significantly owing to add hydroxypropyl methyl cellulose ether and thixotropic agent; The adding of water reducer can increase degree of compactness, further increases water-proof function; Add hydrophober and further reduced water regain; The adding of lignin fibre has improved the splitting resistance at initial stage; The adding of polypropylene fibre improves long-term splitting resistance; Pigment uses ferric oxide series, makes the color of spackling gorgeous more lastingly.
