Abstract

The invention relates to a production and preparation method of an ultrafine filling material. According to the technical scheme, the ultrafine filling material is prepared from 70-80 parts of high-quality coal ash, 10-15 parts of boiler slag, 5-10 parts of tailing sand and 1-5 parts of a modifier; the characteristics of the high-quality fly ash are as follows: the ignition loss is less than or equal to 5%, the 45-micron sieve residue fineness is less than or equal to 20%, the 7-day activity is more than or equal to 60%, the 28-day activity is more than or equal to 80%, and the chloride ion content is less than or equal to 0.06%; and the boiler slag has the characteristics that the water content is less than or equal to 10%, the ignition loss is less than or equal to 10%, and the chlorideion content is less than or equal to 0.06%. The method has the beneficial effects that the production process is improved in a breakthrough manner, the original screening and coarse grinding are changed into fine grinding, and higher raw material utilization rate, lower production cost and better use effect are realized.

Description

technical field [0001] The invention relates to a production process of an inorganic material composition, in particular to a production and preparation method of an ultrafine filling material. Background technique [0002] At present, in the production of oilfield drilling, plastic products, and rubber products, due to operational requirements, quality requirements, and cost requirements, it is necessary to physically fill the corresponding powder materials in the production process, and at the same time use the gelling activity of inorganic particles to achieve The functions of stabilization, connection, sealing and forming achieve the purpose of improving quality and reducing cost. In these industries, there are also improvements through chemical technology, but due to defects such as high cost of use, unstable effect, and high risk of pollution, fewer and fewer companies use it. Contents of the invention [0003] The purpose of the present invention is to address the ...
