Problems solved by technology

[0002] In building construction, it is usually necessary to waterproof the roof, corners, waterways and other places that are prone to water leakage. At present, the method of laying waterproof felt or painting waterproof glue is used. The laying of waterproof felt requires heating, a large workload, and the ground is covered. It cannot be walked or used after being changed; the waterproof glue only forms a waterproof film on the surface, which has poor durability and is not suitable for large-scale use, only suitable for house repairs
[0003] In addition, the treatment of indoor floors, such as bathrooms and kitchen floors, currently uses porcelain floor tiles, which are bonded with cement when laying. Due to the poor waterproof performance of cement, it is easy to leak in the gaps between the floor tiles

Embodiment Construction

[0011] The present invention will be further described below according to the embodiments.

[0012] The preparation process of the embodiment is: Weigh 30% of vinyl acetate-ethylene copolymer emulsion, 10% of methyl methacrylate, add 10% of water, stir evenly, then add 50% of magnesium oxide powder, adjust to paste, and fill stand-by.

[0013] When in use, it is mixed with cement in the same amount and paved directly.

[0014] Using the invention, the strength and bonding force of the cement layer are not affected, and the invention has the advantages of waterproof and leakage prevention, and is convenient to use.

Abstract

The invention relates to cement anti-seep auxiliary material, belongs to the modification auxiliary material of the cement. It is prepared by magnesia powder, vinyl acetate- ethylene copolymerization emulsion, methyl methacrylate and water, the auxiliary material is mixed with the cement to use, waded the slit among the cement grains, made the cement directly possess water resistance, and no need additional waterproof construction for the building. And its using is quite convenient.

Description

technical field [0001] The invention relates to a cement material for construction, in particular to a modified auxiliary material for cement. Background technique [0002] In building construction, it is usually necessary to waterproof the roof, corners, waterways and other places that are prone to water leakage. At present, the method of laying waterproof felt or painting waterproof glue is used. The laying of waterproof felt requires heating, a large workload, and the ground is covered. Change and can not walk, use; brushing waterproof glue just forms a waterproof film on the surface, the durability is poor, and it is not suitable for large-area use, only suitable for house repairs. [0003] In addition, the treatment of indoor floors, such as bathroom and kitchen floors, currently adopts the laying of porcelain floor tiles, which are bonded with cement during laying. Due to the poor waterproofness of cement, it is easy to leak in the gaps between the floor tiles. Conte...
