Compound type powder waterproof agent and preparation method thereof

Abstract

The invention relates to a compound type powder waterproof agent and a preparation method thereof. The compound type powder waterproof agent comprises raw materials of stearate, lignin, hydroxymethyl, calcium substances and silicon dioxide. The compound type powder waterproof agent disclosed by the invention is identical with cement in property and belongs to a rigid inorganic compound cement additive. The compactness and the impermeability of cement and cement mortar in which the compound type powder waterproof agent is added are greatly enhanced; and a three-dimensional water resistant mode is formed, and thus the waterproof effect is excellent and the strength of the concrete is improved by 20-30 percent.

Description

technical field [0001] The invention relates to waterproof engineering in the construction field, in particular to a composite powder waterproofing agent and a preparation method thereof. Background technique [0002] In the field of waterproof engineering in the construction industry, waterproofing is one of the important functional elements, and its waterproofness is second only to the structure. At present, there are many kinds of waterproof materials on the market, which can be divided into coiled materials, powders, emulsions, etc. in terms of form; they can be divided into organic, inorganic and synthetic materials in terms of materials; a large number of waterproof materials play an important role in the development of building waterproofing. played a positive role in the process. With the development of the economy, the requirements for building functions are getting higher and higher. However, due to the influence of materials, objective and subjective factors, the...
