Problems solved by technology

Because the quality of the workers’ craftsmanship is an important factor that determines whether the slope is reasonable, many families find that the floor drain is not at the lowest point of the slope after laying tiles, resulting in water accumulation in the bathroom. Therefore, it is necessary to use a mop to drag the water to the floor drain. , very cumbersome
Some users solve the water accumulation problem by re-laying tiles, but it is time-consuming and labor-intensive
Although there are some waterproof materials on the market, their adhesion on smooth ground with water environment is poor, and it is very easy to fall off

Abstract

The invention discloses a high-adhesive-power waterproof material for a smooth ground and a preparation method thereof. The high-adhesive-power waterproof material for the smooth ground comprises thefollowing ingredients in parts by weight: 25-40 parts of PVDC aqueous emulsion, 5-8 parts of nano titania, 7-10 parts of itaconic acid, 10-15 parts of betaine, 5-8 parts of methyl dihydrojasmonate and1-4 parts of curing agent. The waterproof material disclosed by the invention can be applied to the smooth ground, is high in adhesive power and is not prone to peeling and spalling; the hot and coldwater resisting effect is good, the scratch resistance is high, and the drying rate is high; the waterproof material further has a deodorizing function, and thus, the added value of the product is increased; the use method is simple, and the problem of water accumulation caused by uneven ceramic tiles can be effectively solved.

Description

technical field [0001] The invention relates to a waterproof material, in particular to a high-adhesion waterproof material for smooth ground and a preparation method thereof. Background technique [0002] The toilet is a space for occupants to perform activities such as defecation, bathing, and washing. Ceramic tiles are an important part of bathroom waterproofing. Bathroom walls and floors need to be covered with ceramic tiles that are highly waterproof, corrosion-resistant and mildew-resistant. When laying tiles in the bathroom, it is necessary to set a slope on the ground so that the bath water flows to the floor drain. Because the quality of the workers’ craftsmanship is an important factor that determines whether the slope is reasonable, many families find that the floor drain is not at the lowest point of the slope after laying tiles, resulting in water accumulation in the bathroom. Therefore, it is necessary to use a mop to drag the water to the floor drain. , very...
