Recently, GUARDEX another invention patent was authorized by the State Intellectual Property Office, invention patent name: a waterproof material of back water that can heal with bright water and its preparation method and application, patent number: ZL 2020 1 0585331.1.

According to statistics, China's construction underground engineering leakage rate of 80%, and treatment, difficult, easy to repeated leakage, so the leakage is also known as the building "cancer". The maintenance of underground buildings is more complex, on the one hand, under the water pressure penetration, prone to open water leakage, need water construction; on the other hand, mostly on the back surface, maintenance is difficult and on the performance requirements of waterproof materials is higher.

Most of the existing products in wet or water seepage base surface construction material is not easy to dry hardening, in the environment of high humidity mechanical properties, waterproof performance and corrosion resistance, coating hardening after easy absorption expansion, cannot resist the erosion of water pressure, when the external damage, coating also does not have the self-repair function, cannot effectively solve the problem of leakage.

In view of the problems existing in the prior technology, the present invention provides a bright water and self-healing back water waterproof material, which has the advantages of long-term waterproof, aging resistance, anti-cracking, anti-seepage and antifreeze, easy to make, convenient construction and higher efficiency.

More importantly, the self-repair and self-healing effect of the material can effectively solve the problem of waterproof failure after the coating itself is slightly damaged, so as to achieve an efficient and long-term waterproof effect.

Part of this material can penetrate into the concrete structure through the pores or cracks on the concrete base surface, and react with the free calcium and magnesium ions to form the gel to fill the pores, make the concrete more dense and improve the self-waterproof performance of the concrete, and another part can react with the cement in the material, so that the material can be constructed in the environment with bright water.

After hardening of the material, the coating still retains unreacted ingredients. When a new seepage point or microcracks occur, the material will react again, generating a new gel to plug the seepage point or microcracks, to achieve the effect of self-healing.

Material contains special composition can significantly improve the hole structure, prevent the cement particles mutual cohesion, improve the uniformity of new slurry and hardened body, is conducive to hydration reaction, and particles filled in material pores, can reduce the porosity of the material, improve compactness, to improve the permeability, resistance to freezing and thawing, and resistance to chloride ion and sulfate erosion ability.

The preparation and use of such materials are extremely convenient and efficient, in line with the needs of technical innovation and market changes, can better solve the defect pain points of the back water surface waterproof material, and can stop the bright water, with self-healing and self-repair effect, good durability, green environmental protection, so it has a wide range of application prospects.

Up to now, GUARDEX has applied for more than 80 + technology patents and 39 invention patents, of which 10 of them have been authorized and 42 utility model patents (37 of them are authorized).

In the future, GUARDEX will forge ahead and pay more attention to scientific and technological innovation while forging ahead, so as to realize the transformation of more new technologies, new materials and new processes, and boost the development of the waterproof industry to a new level.
