Abstract

The invention provides a water reduction agent, belonging to the field of building material additives. The building water reduction agent comprises the following components in parts by weight: 4-20 parts of acetone, 10-15 parts of calcium lignosulphonate, 10-14 parts of urea, 4-7 parts of formaldehyde, 1-2 parts of sodium hydroxide, 2-5 parts of melaminen and 1-5 parts of phenol. According to the technical scheme, a preparation method of the water reduction agent comprises the following steps: mixing calcium lignosulphonate, urea and acetone, heating to be 55-65 DEG C, further feeding acetone, formaldehyde, sodium hydroxide, melaminen and phenol, and continuously stirring uniformly, thereby obtaining a product, wherein the products with different solid content can be prepared according to practical demands. The water reduction agent provided by the invention is wide in resource, simple in preparation method, free of toxicity or pollution and low in energy consumption.

Description

[0001] Technical field [0002] The invention relates to a water reducer, which belongs to the field of building material additives. Background technique [0003] Water reducing agent refers to an admixture that can reduce the mixing water consumption and increase the strength of concrete under the conditions of constant workability and cement consumption; or save cement consumption under the conditions of constant workability and strength. [0004] The appearance of water reducing agent is divided into water agent and powder agent. The solid content of water agent is 20%, 40%, 60%, and the solid content of powder agent is 98%. According to the enhancement ability of the water reducing agent, it can be divided into ordinary water reducing agent (plasticizer, water reducing rate not less than 8%), superplasticizer (superplasticizer, water reducing rate not less than 14%) and high performance (reducing water The water rate is not less than 25%), it can also be divided into early stre...
