Embodiment 1
[0019] To prepare a cement-based adhesive, first mix 35% cement, 54.59% sand, 8% calcium carbonate powder, 0.34% water-retaining agent, 2% organic binder, 0.01% thickener, The 0.06% anti-slip agent is dry-mixed uniformly in a mixer to prepare dry powder of the adhesive composition, and then packed into a packaging bag. When in use, add water with a weight of 26% of the dry powder into the container, then add the dry powder of the above-mentioned adhesive composition, and fully stir to form a viscous slurry.
Embodiment 2
[0021] To prepare a cement-based adhesive, first mix 30% cement, 55.58% sand, 10% calcium carbonate powder, 0.36% water-retaining agent, 4% organic binder, 0.02% thickener, The 0.04% anti-slip agent is dry-mixed uniformly in a mixer to obtain dry powder of the adhesive composition, and then packed into a packaging bag. When in use, add 24% water of the dry powder weight into the container, then add the above-mentioned adhesive combination dry powder, and fully stir to form a viscous slurry.

Abstract
The invention provides a cement-based adhesive and a method for preparing the same. The cement-based adhesive is composed of the following dry powder materials: cement, sand, calcium carbonate powder, water-retaining agent, organic adhesive, thickener and anti-sliding agent. The cement-based adhesive is a one-component composition, when used, the cement-based adhesive is added into an appropriate amount of water, and stirred at normal temperature and pressure. The construction process is simple and the cost is low. The cement-based adhesive takes the cement and the organic adhesive as main cementing materials, the sand and the calcium carbonate as the main aggregates, adds proper water-retaining agent, thickener and anti-sliding agent. The cement-based adhesive has such advantages as good construction performance, long drying time, high anti-sliding ability, and high adhesiveness when used for cementing wall and floor tiles. The cement-based adhesive can be widely used to cement various wall and floor tiles, especially stones with large area density such as marble and granite bricks, and can not slide even when the area density is up to 80 kg / m<2>.
Description
Technical field: [0001] The invention relates to a single-component cement-based adhesive and a preparation method thereof, in particular to an adhesive for pasting stone wall and floor tiles such as marble tiles, granite, and ceramic tiles with high surface density and a preparation method thereof. Background technique: [0002] In the prior art, the adhesives for sticking stone and ceramic tiles can be divided into three categories: [0003] 1. Traditional adhesives. These adhesives consist of cement, sand, or cement alone, mixed with water on site and applied. This type of adhesive does not use additives, not only requires skilled construction technology, and the mortar needs to be used in a short time, but also has poor slip resistance and low tensile bonding strength. In addition, when traditional tile adhesives are used to bond wall and floor tiles, the thickness usually needs to be 10-30mm to bond, and the amount of adhesive is large, and the waste rate is also high...
