Anti-cracking inorganic waterproof material and preparation method thereof

Abstract

The invention discloses an anti-cracking inorganic waterproof material which is characterized by comprising the following components in parts by weight: 50-60 parts of cement, 10-15 parts of pyrophyllite powder, 20-25 parts of soapstone powder, 10-15 parts of silicon coal, 0.5-1.5 parts of 2-chloroethoxyethanol ionized tris(dimethylamino) chlorosilane, 0.1-0.3 parts of tetra(2-trichlorosilyl ethyl) silane, 0.1-0.3 parts of pectic acid, 1-3 parts of surface modified Be-Mn-Ca-O, 0.3-0.8 parts of sodium aluminum silicate, 1-2 parts of hyperbranched chitosan, 1-2 parts of black phosphorus, 2-5 parts of blast furnace slag, 0.5-1.5 parts of an expanding agent and 1-2 parts of a water reducing agent. The invention also discloses a preparation method of the anti-cracking inorganic waterproof material. The anti-cracking inorganic waterproof material disclosed by the invention is remarkable in anti-cracking and waterproof effects, convenient to construct, safe and environment-friendly in preparation and construction processes, good in durability and long in service life.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a crack-resistant inorganic waterproof material and a preparation method thereof. Background technique [0002] With the increasing urban construction in our country, the construction projects of subways, underground shopping malls, civil air defense facilities, underground parking lots, and underground corridors are coming one after another. In these construction projects, the leakage problem has always been a difficult and miscellaneous disease that plagues the engineering field. Scientific researchers focus on researching and solving important issues. The harm of leakage can accelerate the development of concrete aging diseases, and cause damage to buildings or even accidents, and the loss will be immeasurable. The use of waterproof materials is currently the main way to solve the problem of penetration in construction projects. As the problem of waterproofing in e...

Problems solved by technology

However, the strength of the crystals formed inside the concrete cannot be guaranteed, and the pores cannot be completely blocked, so the compressive strength and waterproof effect are poor, and the application site is the concrete base surface, the penetration distance is limited, and the thickness of the waterproof layer is also thin. The effect is limited to the surface of the concrete substrate, which can lead to water seepage if the substrate is cracked, worn or weathered
