Problems solved by technology

Although these methods are effective in construction and treatment, one is biologically toxic, and the other is extremely easy to age. Periodic repeated waterproofing treatment is required, and the construction is time-consuming and pollutes the environment.
In order to reduce the troubles caused by leakage, some people have to use decorative boards or resin boards to cover waterproofing, and even more researchers have spent energy screening microbial flora for waterproofing repairs, that is, adding a certain amount of a specific substance to the cementitious material. Microbial bacteria, borrow water under the condition of leakage to activate the metabolism of microbial flora to repair cracks (see Issue 8, 2014, Concrete Theoretical Research, Research Progress in Microbial Self-healing Technology of Concrete), but the large-scale practicability of microbial methods is not yet Doubtful

Abstract

The invention relates to a flexible waterproof board for building floors and external walls. The flexible waterproof board is mainly composed of a flexible functional waterproof layer, fiber cloth, fiber thorn cloth and shaped silk threads; the flexible functional waterproof layer is made of a functional waterproof material and fiber reinforcing ribs, and the functional waterproof material is dry-mixing modified bentonite cement mortar and / or dry-mixing modified bentonite fiber cement mortar; the flexible functional waterproof layer is composed of two or three or four layers of dry-mixing modified bentonite cement mortar and / or dry-mixing modified bentonite fiber cement mortar divided by one or two or three layers of fiber reinforcing ribs; the functional waterproof layer is arranged between the fiber thorn cloth and the fiber cloth, the shaped silk threads penetrate through the fiber thorn cloth and the fiber cloth to be tightly buckled and compacted, and the flexible waterproof boardis formed. The flexible waterproof board adheres to a base layer, the anti-seismic and anti-impact capability is high, and the waterproof effect is good; raw materials are easy to obtain, and manufacturing is simple and convenient; transportation and construction are convenient, and the cost is low.

Description

technical field [0001] The invention relates to a building waterproof material, in particular to a flexible material used for waterproofing of building exterior walls and floors or toilets. Background technique [0002] At present, the leakage of building exterior walls and floors, especially the leakage of toilets, is a headache for people. As we all know, the leakage of the current external wall or floor is due to micro-cracks or connected permeable channels. This is because the existing basic building materials use portland cement as the cementitious material, and the natural The problem of chemical drying shrinkage is easy to produce a large number of micro-cracks or cracks. During the construction of Portland cement cementitious materials, it is necessary to add water far exceeding its hydration water demand, and the excess water will form a large number of capillary channels after curing. Therefore, in order to solve the leakage problem of the building, that is, the ...
