Technical Field
The invention relates to a waterproof material, in particular to a high-adhesion waterproof material for smooth ground and a preparation method thereof.
Background
The toilet is a space for the residents to perform activities such as defecation, bathing, washing and the like. The ceramic tile is an important waterproof component of a toilet, and the wall and the floor of the toilet are both required to be fully adhered with the ceramic tile which has strong waterproofness and is corrosion-resistant and mildew-resistant. When the ceramic tiles are laid in the toilet, the slope needs to be arranged on the ground, so that the bath water flows to the floor drain. As the good or bad handedness of workers is an important factor for the reason that the slope setting is reasonable or not, many families find that the floor drain is not at the lowest point of the slope after the tiles are laid, so that the water is accumulated in a toilet, and the water needs to be dragged to the floor drain by using a mop, which is very tedious. Still others have solved the problem of standing water by re-tiling, but they are time consuming and labor intensive. Although some waterproof materials exist in the market, the waterproof materials have poor adhesion on smooth ground in water environment and are easy to fall off. Therefore, a high adhesion waterproof material for smooth ground is urgently needed in the market.
