A kind of preparation method of high-performance anti-water infiltration material

Abstract

The invention provides a method for preparing a high-performance waterproof infiltration material. The components in the water infiltration-resistant material are mixed according to the following weight ratio: the content of ammonium silicate is 2.0-7.0wt%, ethyl silicic acid The sodium content is 1.2-20.5wt%, the polyacrylate diatomite content is 6.0-13.0wt%, the sand content is 15.0-40.0wt%, the coarse sand content is 4.0-12.0wt%, and the calcium oxide content is 6.0-17.0 wt%, the cement content is 30.0-50.0 wt%, and the additive content is 0.02-0.09 wt%. The invention can be used in waterproof and infiltration fields such as dams, bath pools, pools, basements, and building tops, and has the characteristics of high water infiltration resistance, long waterproof effective time, non-toxic and harmless, 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...

AI Technical Summary

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
