Comprehensive dispersing agent capable of adjusting construction time in refractory material and preparation method of comprehensive dispersing agent
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.
本发明提供了一种用于耐火材料中可调节施工时间的综合型分散剂，包括以下组分，各组分以及各组分的质量份为：羧酸单体500～700份、金属单体20～50份、长链单体50～100份、羟基单体100～200份，纯化水40～80份、分子量控制剂1～4份、引发剂0.5～1.5份、缓释粉体300～500份；所述金属单体为乙烯基三氟硼酸钾、乙烯基硼酸频哪醇酯、乙烯基锂、4‑乙烯基苯磺酸钙中的一种或两种以上的混合物。所述综合型分散剂粉体均匀，使用方便简单，且在常温环境下保存24个月不会失效，对于矾土及高硅体系耐火浇注料有良好的分散作用，能够根据外界的施工环境来调节施工时间的长短。
