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

Abstract

The invention discloses a dry-type micro-expansion thermal insulation coating for a glass kiln, which is characterized in that it contains the following raw materials in parts by weight: 30-60 parts of expanded perlite, 20-40 parts of superfine surface-active heavy calcium carbonate, silicon 5-10 parts of aluminum acid fiber, 2-5 parts of siliceous fine powder, 2-5 parts of hollow fiber, 5-13 parts of composite binder, 1-4 parts of chemical additives; Active ground calcium carbonate, aluminum silicate fiber, siliceous fine powder, and hollow fiber are put into the mixer in turn and mixed evenly, and then the remaining composite binder and chemical additives are added into the mixer and stirred until they are fully mixed. The dry thermal insulation coating made from the above-mentioned raw materials in the present invention not only reduces the stagnant material defoaming and standing link after foaming, but also avoids the problems of deterioration and dehydration caused by long-distance transportation of traditional slurry coatings. It has the characteristics of remarkable heat preservation and energy saving effect, convenient construction and so on.

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
