Problems solved by technology

During the construction of refractory materials, it is greatly affected by the external temperature. In the high temperature environment in summer, the refractory materials will condense in a short time, which leads to a shorter construction time and affects the completion of the construction.
In the low temperature environment in winter, the condensation of refractory materials is too long, which affects the construction efficiency

Abstract

The invention provides a comprehensive dispersing agent capable of adjusting construction time for a refractory material. The comprehensive dispersing agent comprises the following components in partsby mass: 500-700 parts of a carboxylic acid monomer, 20-50 parts of a metal monomer, 50-100 parts of a long-chain monomer, 100-200 parts of a hydroxyl monomer, 40-80 parts of purified water, 1-4 parts of a molecular weight control agent, 0.5-1.5 parts of an initiator and 300-500 parts of slow-release powder, wherein the metal monomer is one or a mixture of two or more of vinyl potassium trifluoroborate, vinyl boronic acid pinacol ester, vinyl lithium and 4-vinyl benzene sulfonic acid calcium. The comprehensive dispersing agent is uniform in powder and convenient and simple to use, does not lose efficacy after being stored for 24 months in a normal-temperature environment, has a good dispersing effect on alumina and high-silicon system refractory castables, and can adjust the constructiontime according to an external construction environment.

Description

technical field [0001] The invention belongs to the technical field of polymer synthesis and relates to a dispersant, in particular to a comprehensive dispersant used in refractory materials with adjustable construction time. Background technique [0002] The dispersion of inorganic materials in aqueous solution has always been a major problem in coatings, construction and other industries. The existing dispersants have many major drawbacks, especially for refractory materials. Refractory materials are ceramic materials used in high-temperature environments. At present, there are problems such as excessive addition of dispersants for refractory materials, selectivity to the system, and failure of some inorganic materials. At this stage, most of the industry still uses some old-fashioned inorganic materials such as sodium tripolyphosphate for dispersion. This kind of dispersant for refractory materials does not have the function of adjusting the construction time of refractor...
