Glass kiln-used dry type micro-expansion heat preservation coating

Abstract

The invention discloses a glass kiln-used dry type micro-expansion heat preservation coating which is characterized by comprising the following ingredients in part by weight: 30-60 parts of expanded perlite, 20-40 parts of superfine surface active ground calcium carbonate, 5-10 parts of alumina silicate fiber, 2-5 parts of siliceous fine powder, 2-5 parts of hollow fiber, 5-13 parts of composite binding agent, and 1-4 parts of chemical additives. When being prepared, the expanded perlite, the superfine surface active ground calcium carbonate, the alumina silicate fiber, the alumina silicate fiber and the hollow fiber are put into a stirring machine in sequence to be uniformly stirred and mixed up; the reset composite binding agent and the chemical additives are added into the stirring machine to be stirred and sufficiently mixed so as to prepare the coating. According to the coating, the raw materials are prepared into the dry type heat preservation coating, so that not only are the procedures of mixture ageing, defoaming and standing after foaming reduced, but also the problem that a traditional coating is deteriorated and dehydrated caused by long distance transportation is avoided; and meanwhile the coating has the characteristics of rapid curing strength, remarkable heat preservation and energy conservation effect, convenience for construction and the like.

Description

technical field [0001] The invention belongs to the field of refractory materials, and in particular relates to a dry micro-expansion thermal insulation coating for a glass kiln. Background technique [0002] With the rapid development of the market economy, the consumption of resources and energy has increased significantly. Energy saving and consumption reduction has become the common goal of enterprises. The use of thermal insulation products is the most common and effective means for high-temperature production enterprises to achieve energy conservation and consumption reduction. Driven by market demand, many experts and scholars have done a lot of fruitful work. Thermal insulation and energy-saving products have developed rapidly, product performance has been significantly improved, and product applications have gradually become refined, but there are still certain deficiencies. At present, the common industrial thermal insulation coatings on the market are mostly slurr...

Problems solved by technology

At present, the common industrial thermal insulation coatings on the market are mostly slurry coatings, which have problems such as high shrinkage at high temperature, which may easily cause a large number of through pores and reduce the thermal insulation effect; coatings are prone to powdering, cracking or even falling off during long-term use; use Wide coverage and low pertinence, unsuitable use temperature leads to poor actual use effect; complex production process, high production cost and high difficulty in storage and transportation; paint is greatly affected by ambient temperature and other problems
