Description
Technical Field
The invention relates to the field of building materials, in particular to a cement-based tile adhesive and a composition for preparing the adhesive.
Background
At present, marble materials or ceramic tiles are mostly used for building floors on the market, and the marble materials or the ceramic tiles have the characteristics of easiness in cleaning, stain resistance, water resistance, corrosion resistance, wear resistance and the like, so that the building floors are widely used for floor decoration of public places such as civil buildings, large-sized markets, office buildings, hospitals and the like, and when the marble materials or the ceramic tiles are constructed, the ceramic bonding materials are used for bonding the marble materials or the ceramic tiles to the ground.
At present, the tile sticking material is mainly a cement-based tile adhesive which is popularized and used, and the adhesive is used for sticking tiles by utilizing the occlusion force and the van der Waals molecular force, thereby being very suitable for the trend of the current tiles towards low water absorption rate. However, the widespread effect of cement-based tile adhesives is not ideal at present, and the main reasons for this are: because the cement-based tile adhesive has good water-retaining property, the drying speed of the cement-based tile adhesive is slow, and the probability of shrinkage of the tile adhesive is increased along with the increase of the thickness of the tile adhesive, the interface bonding strength is low, and the brick falling phenomenon is likely to occur, so the cement-based tile adhesive needs to adopt a thin-pasting method (the pasting thickness is 3-5 mm). However, the prior domestic building wall surface is difficult to meet the requirement of a thin pasting construction method on the flatness of the wall surface (a guiding rule with the length of 2m is used for checking the flatness of a base layer, and the tolerance cannot exceed +/-3 mm). In addition, the cost of using cement-based tile adhesives is high and still unacceptable for most projects.
Disclosure of Invention
In order to solve the problem that the existing cement-based tile adhesive can not be pasted thickly, the invention provides a tile adhesive which is quick-drying and can be pasted thickly and a composition for preparing the tile adhesive.
In order to realize the purpose of the invention, the following technical scheme is adopted for realizing the purpose:
the cement-based tile adhesive comprises a composition, wherein the composition comprises the following raw materials in percentage by mass:
the composition also comprises sand, wherein the mass ratio of the composition to the sand is as follows: the composition and sand are 1: 4.
Because the proportion of the quartz sand in the invention reaches 80 percent, the anti-shrinkage capability of the system is greatly improved, the invention can be constructed for one time without shrinkage of 50mm, can achieve the integrated effect of leveling the base course and pasting the ceramic tiles, is suitable for the current situation that the base course is not flat at present, greatly reduces the application difficulty of the cement-based ceramic tile adhesive, reduces the requirement on constructors, and is very suitable for comprehensive popularization. Wherein, because the composition is added with the coagulation accelerating early strength agent, the early strength is high, and the composition can be applied to people after being pasted for 6 hours at normal temperature, and the drying speed is 50 percent faster than that of the traditional ceramic tile adhesive.
In addition, the composition in the formula can be called as concentrated tile adhesive, can be directly packaged and delivered, and can be directly used for obtaining the tile adhesive by taking medium sand and water and stirring into paste on a construction site. The formula of the composition provided by the invention only comprises the powder of the tile adhesive, does not comprise sand, and utilizes the convenience of taking quartz sand at a construction site nearby, so that the transportation cost of the traditional tile adhesive from a factory to the construction site is reduced compared with that of the traditional tile adhesive, the transportation cost of 1 ton of concentrated tile adhesive is equivalent to that of 5 tons of traditional tile adhesive, the production cost and the transportation cost from the factory to the construction site can be greatly reduced, and the cost reduction range reaches 80%.
In practical application, the composition and the medium sand on the construction site are taken, the mixing mass ratio of the composition to the medium sand is 1:4, after the mixture is uniformly mixed, water accounting for 10% -15% of the total mass is added, and the mixture is stirred into paste to be directly used. Wherein the total mass refers to the sum of the mass of the composition and the mass of the sand. For the cement-based tile adhesive obtained after water is added, the proportion of sand (aggregate) in the whole system is 70-73%, and the system has excellent shrinkage resistance, small shrinkage rate and high interface bonding strength, and is very suitable for being applied to a thick paste process.
Further, the quartz sand used by the traditional tile adhesive is selected quartz sand, the factory machine is generally adopted to select and grade standard quartz sand, the price is high (about 300 yuan/ton), the concentrated tile adhesive uses the existing concrete medium sand (the grain diameter is about 0.25-0.5 mm) of a construction site, and the price of the medium sand of the construction site is low (about 50 yuan/ton). Meanwhile, the proportion of quartz sand in the tile adhesive in the formula provided by the invention accounts for more than 65%, and according to the calculation, compared with the traditional tile adhesive, the tile adhesive obtained by mixing the concentrated tile adhesive with sand in a construction site can be reduced by about 162.5 yuan per ton of tile adhesive, so that the production cost of the invention is greatly reduced. In addition, the tile adhesive obtained by mixing the concentrated tile adhesive with the sand in a construction site has high bonding strength and good water resistance and heat resistance.
Further, the Portland cement is Portland cement No. 42.5 or Portland cement No. 52.5; the sulphoaluminate cement is No. 42.5 low-alkalinity quick-hardening sulphoaluminate cement or No. 52.5 low-alkalinity quick-hardening sulphoaluminate cement; the latex powder is one or more of vinyl acetate and ethylene copolymer rubber powder, ethylene, vinyl chloride and vinyl laurate ternary copolymer rubber powder, vinyl acetate, ethylene and higher fatty acid vinyl ester ternary copolymer rubber powder, vinyl acetate and higher fatty acid vinyl ester copolymer rubber powder, vinyl acetate, acrylate and higher fatty acid vinyl ester ternary copolymer rubber powder, acrylate and styrene copolymer rubber powder or acrylic acid homopolymerization rubber powder, and butadiene and styrene copolymer rubber powder; the cellulose ether is hydroxyethyl methyl cellulose ether and/or hydroxypropyl methyl cellulose ether, and the viscosity is 20000 mPa.S-50000 mPa.S; the guar gum powder is guar gum powder, and the viscosity is 60000-200000 mPa.S; the early strength agent is calcium salt series.
Compared with the prior art, the cement-based tile adhesive provided by the invention has the advantages that the amount of aggregate (sand) in the formula is increased to more than 65%, the shrinkage rate of the system is well reduced, the tile adhesive can be pasted thickly, and meanwhile, the production cost is greatly reduced. The invention also provides a composition for preparing the tile adhesive, and the composition can greatly reduce the transportation cost and the production cost of the tile adhesive and further reduce the application cost due to the full utilization of the medium sand in a construction site.
