Composite concrete additive aqua antiseptic agent

Abstract

The present invention discloses a composite concrete additive aqua antiseptic agent, belonging to the cement product technology field. The antiseptic agent comprises following components: A. iodo propynylbutyl carbamate; B. methyl dibromo pentanedinitrile; C. sulfamic acid water reducing agent with the solid content of 30% and synthesized by the phenol and the sodium p-toluenesulfonate; D. oxidized sodiumlignosulfonate with the solid content of 30%. The invention has the following advantages of broad spectrum sterilization, such as bacteria (gram positive bacteria and gram negative bacteria), fungi, and yeast; stabilization and availability in a wide pH value range; excellent physical and chemical compatibility; non-color changing in the container and the lacquer film; low toxicity in the recommended addition level and biological degradation.

Description

technical field [0001] The invention relates to a building material, in particular to a preservative for a composite concrete admixture water agent, and belongs to the technical field of cement products. Background technique [0002] During the application process, concrete admixture products generally appear in the form of water agents, and some products will also add a small amount of functional group chemicals with corresponding properties according to the requirements of concrete construction and performance. During the use and storage of the water agent, it will deteriorate and cause corruption, especially in summer. Therefore, adding the preservative that suppresses the spoilage of the aqueous solution in the aqueous solution is one of the main methods to solve its product defects. At present, it is mainly used to use a small amount of formaldehyde, or a small amount of free formaldehyde after the condensation is completed, or use some antiseptic chemicals such as sod...

AI Technical Summary

Problems solved by technology

At present, it is mainly used to use a small amount of formaldehyde, or a small amount of free formaldehyde after the condensation is completed, or use some antiseptic chemicals such as sodium benzoate and sorbic acid as the antiseptic component of the water agent, and its performance is not stable enough, mainly reflected in the solution The formaldehyde in the solution escapes with the change of storage time and temperature, or the influence of the pH value of the solution on the anticorrosion performance will still cause corruption.
