Problems solved by technology

Among them, asphalt and polyurethane resin waterproof materials have been banned by the state due to serious pollution and toxicity; acrylic acid and acrylamide polymer waterproof materials have poor durability, are easy to age, and have a short life. In addition, once the waterproof film layer is damaged, Leakage occurs immediately
Patent CN201810116545.7 discloses a waterproof material for building construction and its preparation method. The patent uses raw materials such as epoxy resin, polyurethane resin, quartz sand, asphalt, and zirconia. Although it has a certain waterproof effect, it has Not long service life
Patent CN1800291 discloses a plugging waterproof material, the plugging waterproof material is composed of Portland cement 24-60%, high alumina clinker 20-63%, aluminum potassium sulfate dodecahydrate 0-10%, di Water gypsum 1-5%, sodium polyacrylate 0-1%, bentonite 2-10%, latex powder 0-2%, quartz sand 10-20%, although it has the effect of slowing down the infiltration of water in a short time, However, after prolonged use, water can still seep into the
Patent CN108359292A discloses a preparation method of cement-based waterproof material. The material uses water, ethanol, silane coupling agent, sodium-based bentonite grinding and sodium hydroxide as raw materials. Not only the process is complicated, but the waterproof effect is not ideal

Embodiment 1

[0016] First, add 1Kg of ammonium silicate and 6Kg of ethyl sodium silicate into the container, then add 1Kg of water and stir well to make it evenly mixed, then add sodium polyacrylate-diatomaceous earth 10Kg, 100 mesh sand 26Kg, 10 mesh 6Kg of coarse sand, 1Kg of calcium oxide, 49Kg of Portland cement and 0.03Kg of additives are mixed thoroughly to prepare a high-performance water-resistant material. During construction, the water-resistant infiltration material is mixed with water (the mass ratio of waterproof infiltration material to water is 2:1), stirred evenly, and spread on the roof or the ground with a thickness of 2-8cm.

Embodiment 2

[0018] First, add 3Kg of ammonium silicate and 5Kg of sodium ethyl silicate into the container, then add 1Kg of water and stir well to make it evenly mixed, then add sodium polyacrylate-diatomaceous earth 8Kg, 120 mesh sand 30Kg, 20 mesh 4Kg of coarse sand, 2Kg of calcium oxide, 47Kg of Portland cement and 0.05Kg of additives are mixed thoroughly to prepare a high-performance anti-water infiltration material. During construction, the water-resistant infiltration material is mixed with water (the mass ratio of waterproof infiltration material to water is 2:1), stirred evenly, and spread on the roof or the ground with a thickness of 2-8cm.

Embodiment 3

[0020] First, add 5Kg of ammonium silicate and 4Kg of ethyl sodium silicate into the container, then add 1Kg of water and stir well to make it evenly mixed, then add sodium polyacrylate-diatomite 6Kg, 150 mesh sand 30Kg, 40 mesh 7Kg of coarse sand, 3Kg of calcium oxide, 44Kg of Portland cement and 0.08Kg of additives are mixed thoroughly to prepare a high-performance water-resistant material. During construction, the water-resistant infiltration material is mixed with water (the mass ratio of waterproof infiltration material to water is 2:1), stirred evenly, and spread on the roof or the ground with a thickness of 2-8cm.

Abstract

The invention provides a preparation method of a high-performance water-permeation-resistant material. The water-permeation-resistant material is prepared by mixing components according to the following weight ratios that the content of ammonium silicate is 2.0-7.0 wt%, the content of sodium ethyl silicate is 1.2-20.5 wt%, the content of polyacrylate-diatomite is 6.0-13.0 wt%, the content of sandysoil is 15.0-40.0 wt%, the content of coarse sand is 4.0-12.0 wt%, the content of calcium oxide is 6.0-17.0 wt%, the content of cement is 30.0-50.0 wt%, and the content of additives is 0.02-0.09 wt%.The water-permeation-resistant material can be applied to the fields of waterproof infiltration of dams, bathing pools, pools, basements, building tops and the like, and has the characteristics of high water permeation resistance, long waterproof effective time, no toxicity or harm, and convenient use.

Description

technical field [0001] The invention belongs to the field of preparation of waterproof infiltration materials, and relates to a preparation method of a high-performance waterproof infiltration material, which is used in waterproof fields such as dykes, baths, pools, basements, and building tops, and can also be used to improve barren soil that does not retain water. Background technique [0002] Waterproof infiltration material is a very important material that plays an important role in roofs, highways, airports, reservoir embankments, bathrooms, kitchens, tunnels, swimming pools, etc. The quality of waterproof infiltration material is directly related to the quality of engineering construction. With the continuous improvement of social living conditions, people have higher and higher requirements for waterproof infiltration materials. With the rapid development of science and technology, waterproof materials have experienced the development process of asphalt, polyurethan...
