Waterproof and moisture-proof floor

Abstract

The invention discloses a waterproof and moisture-proof floor, which comprises a surface layer, a waterproof and moisture-proof layer and a water filtering layer from top to bottom. The waterproof and moisture-proof layer is prepared from the following components in parts by weight: 100 parts of cement, 100-200 parts of fine aggregate, 1-5 parts of a cementing material, 2-6 parts of fibers, 1-3 parts of an early strength agent and 0.1-2 parts of a water reducing agent; the cementing material comprises hydrophobic redispersible latex powder and a water filtering cementing material in a weight ratio of 2: 1; the water filtering cementing material is prepared from the following components in parts by weight: 5 to 20 parts of non-hydrophobic redispersible latex powder, 20 to 50 parts of dense silica fume, 50 to 80 parts of mineral powder and 0.1 to 0.5 part of a water-reducing retarder; and the water filtering layer comprises the following raw materials in parts by weight: 100 parts of cement, 400-600 parts of coarse aggregate, 8-15 parts of basalt fibers and 10-15 parts of a water filtering cementing material. The water filtering layer is arranged below the waterproof and moisture-proof layer, so that water vapor accumulation between a structural layer and a terrace surface layer is effectively avoided, and the overall mechanical property and waterproof and moisture-proof properties of the terrace reach a good balance relationship.

Description

technical field [0001] The invention belongs to the field of floors, in particular to a waterproof and moisture-proof floor. Background technique [0002] The floor refers to the ground that uses specific materials and techniques to carry out construction treatment on the original ground and presents a certain degree of decoration and functionality. Waterproof and moisture-proof floor is a common floor, which is suitable for many occasions that need to focus on waterproof and moisture-proof treatment, such as basements. Most of the existing waterproof and moisture-proof floors only consider how to prevent the accumulated water on the floor from penetrating downwards, so only one deck of waterproof and moisture-proof layer is pre-laid under the surface layer. However, when the groundwater pressure is high or cracks appear in the floor structure, the groundwater moves upward through direct infiltration and water vapor and gathers under the floor surface layer, resulting in bu...

Problems solved by technology

However, this material cannot solve the problem of how to quickly remove the water vapor or condensed water accumulated between the ground surface and the waterproof and moisture-proof layer. The waterproof performance of the prepared floor material still has room for improvement, and the flexibility and crack resistance need to be further enhanced.

Another example is that the patent CN104418566A provides a flat moisture-proof material, which discloses raw materials such as Portland cement, sulphoaluminate cement, water reducer, quartz sand, water repellent, and redispersible latex powder. The only single method to solve the moisture-proof problem, once leakage occurs, it will still cause damage to the floor surface
