Abstract
The invention relates to a light thermal insulation coating, which is characterized by consisting of refractory cellucotton, aluminate cement, flint clay powder, micro-porous light mullite powder, clay and solid water glass powder, wherein the materials are stirred by adding water and then subjected to coating construction. The light thermal insulation coating is characterized by comprising the following coating raw materials in percentage by weight: 15-30 percent of refractory cellucotton, 15-20 percent of micro-porous light mullite powder, 20-30 percent of aluminate cement, 10-20 percent of flint clay powder, 3-10 percent of clay and 3-6 pecent of solid water glass. The proportioned mixture is uniformly stirred, 20-45 percent of water is added, the mixture is stirred to a proper state to perform coating construction, and the materials are adhered to a construction body. The light thermal insulation coating has the advantages of good thermal insulation effect, high extreme cold and heat resistance, easiness in improvement on strength and coating, friendliness to operation environment, manual direct coating, high adhesion and capability of being constructed on a wall surface and a steel plate without an anchor member at any angle.
Description
Technical field
The invention belongs to fire resisting material field, refer more particularly to a kind of light thermal-insulation coating.
Background technology
Along with the fast development of world economy, energy day is becoming tight.The energy is the basis of our human survival, in energy-intensive today, seeks new forms of energy or excavate substitute energy no doubt important, also is to change present energy-intensive important means but improve energy utilization rate.Especially in the highly energy-consuming industry, on high temperature kiln, energy-conservationly stand in the breach especially.In all kinds of conservation measuress, thermal insulation technology is because energy-conservation huge, invests lessly simultaneously, is easy to realize, thereby is widely used.
The knowledge of inquiry document, on light heat insulation material is selected, traditional lightweight insulating brick high insulating effect; But also exist the defective that intensity is low, use temperature is low simultaneously; Adopt the alumina bubble brick use temperature high, but cost is high, has the brickwork joint crack simultaneously; Globality is not strong, the shortcoming that thermosteresis is big; Lightening casting material exists amount of water big, and linear shrinkage is big, the shortcoming of easy of crack; The alumina silicate fibre blanket use temperature is at 1100 ℃, but construction is inconvenient.
Explained among the patent documentation CN200910000306.6 at home and have similar heat-insulating fiber coating of the present invention, but the present invention has different significantly with it.The raw material that uses is different, and the present invention adopts the littler light porous mullite material of thermal conductivity, and the employing thermal conductivity is little, the flint clay fine powder of Heat stability is good replaces the high alumina fine powder, has added the coking property that clay and water glass are easier to smear and improve material.In addition, concrete construction technology is different, and the scene adds water, and on-the-spot use can prolong the preservation period of product significantly, thereby this product over-all properties is more excellent, and flexibility is wider.
Summary of the invention
The objective of the invention is deficiency, a kind of heat-insulating fiber coating is provided in order to address the above problem.
The technical scheme that the present invention adopts is: a kind of light thermal-insulation coating; It is characterized in that described coating is made up of refractory fiber cotton, light porous mullite powder, aluminate cement, flint clay silty clay soil, solid water glass powder, add and smear construction after water stirs; Described insulation coating is characterized in that the raw material weight per-cent of said coating is: refractory fiber cotton 15-30%, aluminate cement 20-30%, flint clay powder 10-20%, light porous mullite powder 15-20%, clay powder 3-10%, solid water glass 3-6%; Described coating size composition per-cent is: refractory fiber cotton 0-15mm, light porous mullite powder 200 orders, aluminate cement 325 orders, flint clay powder 325 orders, clay powder 250 orders, solid water glass 200 orders; With refractory fiber cotton, flint clay fine powder, light porous mullite powder, clay powder, solid water glass mixing, pack after the stirring earlier, transport the working-yard then to; When constructing at the scene; Add aluminate cement, stir, add entry 20-45%; Be stirred to proper state and smear construction, material adhesive is got final product to the construction body.
The invention has the advantages that: the first, high insulating effect, anti-extremely cold very hot property is strong, has adopted the littler light porous mullite material of thermal conductivity, and the employing thermal conductivity is little, the flint clay fine powder of Heat stability is good; The second, be easy to intensity and smear, added the coking property that clay and water glass are easier to smear and improve material; The 3rd, concrete construction technology is different, field mix, and on-the-spot the use, the preservation period that can prolong product significantly, thus this product over-all properties is more excellent, and flexibility is wider.In addition, operating environment is friendly, and manual work is directly smeared, and tack is good, can be in arbitrarily angled construction on the metope of no anchoring piece, on the steel plate.
Embodiment
Through non-limiting example, essential characteristic of the present invention and construction are described below.
The material component of selecting for use is: refractory fiber cotton length 0-15mm, light porous mullite powder 200 orders, aluminate cement 325 orders, flint clay powder 325 order orders, clay powder 250 orders, solid water glass 200 orders.The raw materials weighing weight percent is: refractory fiber cotton 29%, light porous mullite powder 15%, aluminate cement 30%, flint clay powder 20%, clay powder 3%, solid water glass 3%.With refractory fiber cotton, light porous mullite powder, flint clay fine powder, clay powder, solid water glass mixing, pack after the stirring earlier, transport the working-yard then to; When constructing at the scene; Add aluminate cement, stir, add entry 35%; Be stirred to proper state and smear construction, material adhesive is got final product to the construction body.The mixture of preparation is smeared moulding in Standard Module as stated above, then through 110 ℃
