Efficient impervious leakage-blocking waterproof material and preparation method thereof

Abstract

The invention discloses an efficient impervious leakage-blocking waterproof material. The material is prepared from the following raw materials in parts by weight: 40-50 parts of an elastic acrylic emulsion, 0.5-1.5 parts of a chemical root resistant, 15-25 parts of calcined kaolin powder, 6-12 parts of calcined vermiculite powder, 1-3 parts of a hydroxide solution, 1-4 parts of an nano additive, 2-5 parts of a thickening agent, 8-14 parts of reinforced fibers and 18-24 parts of water. The waterproof material disclosed by the invention has excellent cold resistance, heat resistance, aging resistance and water tolerance, is not deformed to flow at a high temperature, is not fractured at a low temperature and can resist high-frequency repeated impact of rainstorm, and slight deformation can be automatically restored; and meanwhile, the raw material components are safe, reliable and have no environmental pollution, the raw materials are easily available and relatively low in cost, a process is simple and clear, and the waterproof material has relatively high practical values and good application prospects.

Description

technical field [0001] The invention relates to the technical field of waterproof materials, in particular to a high-efficiency anti-seepage plugging waterproof material and a preparation method thereof. Background technique [0002] At present, mainstream waterproof materials mainly include waterproof coiled materials, polyurethane waterproof coatings, polymer cement-based waterproof materials, and cement-based osmotic crystalline waterproof materials. Among them, cement-based osmotic crystalline waterproof materials form water-insoluble crystals in concrete. , Block the capillary channels, so that the concrete is dense and waterproof. However, in practical applications, it has been found that such materials can be used as waterproof materials on indoor walls and floors, but they are often used as roof waterproof coatings in areas with frequent extreme weather such as heavy rain and hail, and leakage often occurs soon after use. [0003] The reason for the above phenomenon...

Problems solved by technology

[0004] The principle of repeated impact is neither the same as static pressure nor similar to the fatigue of continuous circulation, but a kind of impact fatigue. Therefore, even waterproof coatings with good compressive strength and osmotic pressure , It does not mean that it can have good impact fatigue resistance, especially weather such as heavy rain and hail will reduce the temperature of concrete, making the waterproof material more brittle and more likely to be damaged under impact fatigue

In the testing process of national standards, waterproof materials are often only tested for their impermeability under static water pressure, and only a small number of materials are tested for fatigue properties (such as waterproof membranes), while impact fatigue tests are ignored.

[0005] On the other hand, in big cities, because there is a lot of green in the city, there are many roof gardens for people to rest and bring people a lot of fun and health. big test

The anti-seepage and waterproof material produced by the prior art has poor waterproof performance, and the manufacturing process is complicated, time-consuming and laborious. The strong root system of the plant often pierces the anti-seepage and waterproof material, and leakage often occurs on the roof of the building. The existing commercially available anti-seepage waterproof High cost of materials, expensive, difficult to popularize and apply
