Description

High-energy-gathering carbonization-prevention inorganic waterproof coating and preparation method and application thereof
Technical Field
The invention relates to the technical field of waterproof coatings, in particular to a high-energy-gathering carbonization-prevention inorganic waterproof coating, and a preparation method and application thereof.
Background
"carbonation" of concrete means that Ca (OH) is formed after hydration of cement mixed with concrete2Mostly in the crystalline stateThe sodium silicate is present in concrete, becomes a reserve for keeping high alkalinity of pore liquid, and has a pH value of 12.5-13.5. Presence of CO in air2And moisture, CO in air2Will permeate into concrete under the action of water and react with Ca (OH)2And (5) reacting, and reducing the pH value to 8.5-9.0, wherein the concrete is carbonized. Carbonization of concrete is essentially a process in which the pH of the concrete decreases and loses alkalinity. The concrete carbonization starts from the surface layer, then gradually diffuses to the deep part of the concrete, a more deep carbonization reaction occurs, the carbonized concrete is loose in texture, and the strength is greatly reduced. The anti-carbonization ability of concrete is an important index for measuring the durability of concrete structures. The low carbonization resistance of concrete results in poor durability of buildings and reduced service life.
The polymer cement-based waterproof coating is characterized in that an elastic film layer with cohesiveness and continuity is formed on the basis of water loss of an organic polymer emulsion, cement absorbs water in the emulsion to harden, a flexible polymer and a cement hardened body penetrate through each other to be firmly bonded into a firm and elastic waterproof layer, the flexible polymer is filled in gaps of the cement hardened body, so that the cement hardened body is more compact and elastic, a coating film has better elongation, and the cement hardened body is filled in the polymer phase, so that the cement hardened body has better outdoor durability and better base layer adaptability. Therefore, the waterproof coating has certain rigidity, certain toughness and high cohesiveness, and can be made to be thin, and in addition, the waterproof coating is an environment-friendly coating and does not influence the environment, so that the waterproof coating is more and more favored by people and becomes a hotspot for the development of the waterproof coating in recent years. However, the polymer has poor compatibility with cement, long setting time and closes the concrete pores to prevent CO2Other substances are diffused into the concrete, and the organic coating has poor aging resistance, poor compatibility with cement inorganic materials and unsatisfactory carbonization resistance.
