Abstract

The invention discloses a water-based capillary crystalline type waterproof material with the controllable reaction speed as well as a preparation method and an application of the waterproof material. The waterproof material is mainly prepared from raw materials in parts by weight as follows: 30-40 parts of sodium silicate, 0.05-0.15 parts of a surfactant, 0-1 part of a reaction retarder, 0.1-0.2 parts of a reducing agent, 0-5 parts of a reaction accelerant, 0.06-0.1 parts of an anti-freezing agent, 0.1-0.3 parts of a metal ion blocking agent, 0.4-0.8 parts of a surface enhancer, 0.2-0.4 parts of an antirust agent and 53-69 parts of deionized water. The waterproof material has properties of lasting water resistance, durability, aging resistance, good permeability resistance, cracking resistance, high seepage capacity and the like and can reach the optimal waterproof effect for concrete under different porosity conditions; besides, the preparation method is simple, low in cost, pollution-free and convenient to conduct in concrete waterproof application.

Description

technical field [0001] The invention belongs to waterproof materials for buildings, and in particular relates to a water-based permeable crystalline waterproof material with controllable reaction speed, a preparation method and application thereof. Background technique [0002] Water-based permeable inorganic waterproofing agent is based on alkali metal silicate solution, adding catalysts and additives, and reacting through mixing. It is a waterproofing agent with permeability and can seal capillary channels and cracks of cement mortar and concrete. Its main technical principle is that the main component silicate penetrates into the capillary channels of cement mortar or concrete, and Ca(OH) produced during the cement hydration process 2 Reaction, generate calcium silicate hydrate gel (C-S-H) which is insoluble in water, thereby blocking internal pores, closing capillary channels, increasing compactness, forming a permanent sealing waterproof layer integrated with concrete, ...
