Composite silicate high-viscosity cold-hot coating heat preservation slurry

Abstract

The invention relates to a composite silicate high viscosity hot and cold smear insulation slurry, which is prepared by the following materials mixed with water and comprises: expanded perlite 4 to 9 percent by weight, diatomite 2.8 to 6 percent by weight, hill cork 1.2 to 2.6 percent by weight, bentonite 3 to 6.5 percent by weight, alumina fiber 1 to 2.5 percent by weight, glass fiber 1 to 2.5 percent by weight, alumino-silicate fiber 1 to 2.5 percent by weight, vermiculite 0.5 to 1.3 percent by weight, polyvinyl alcohol 1.2 to 2.6 percent by weight, sodium silicate solution 0 to 0.2 percentby weight, and marginal water. The slurry is compounded by the above components, the inner part of the material forms a plurality of closed micropores, and the density is reduced obviously; the micropores are filled with static air having weaker heat conductive property, which can restrain the transmission of external heat effectively. The composite silicate high viscosity hot and cold smear insulation slurry has the advantages of light weight, low thermal conductivity, obvious heat preservation, insulation and deafening effect, high tensile strength, water and oil resistance, wide applied temperature scope and high bond force.

Description

technical field [0001] The invention relates to an energy-saving building material, in particular to a composite silicate high-viscosity cold and hot coating thermal insulation slurry used for equipment, pipelines, houses and the like. Background technique [0002] In order to prevent industrial equipment and heating pipes from losing heat and causing adverse effects on the ambient temperature, it is often necessary to apply a layer of insulation material on the outer surface of the equipment and pipes. Traditional thermal insulation materials are basically single raw materials, such as asbestos, mineral wool, ultra-fine glass brocade, aluminum silicate fiber felt and other thermal insulation materials. This type of material has a good fiber structure, so the tensile strength is good, but there are disadvantages such as poor structural stability, soft materials, and strong gas convection and radiant heat, so the insulation effect is poor. [0003] Insulation slurry made of ...

This type of material has a good fiber structure, so the tensile strength is good, but there are disadvantages such as poor structural stability, soft materials, and strong gas convection and radiant heat, so the insulation effect is poor

[0003] Insulation slurry made of one or more insulation materials such as perlite, rock wool, ultra-fine glass wool, and aluminum silicate that appeared in the later period has been used for insulation of houses, heating pipes, equipment, etc., but Some thermal insulation pastes can only be applied cold, and many products have unsatisfactory adhesion, low tensile strength, brittleness, and fragility. The thermal insulation slurry coating on the equipment is often easy to fall off, which directly affects the thermal insulation effect
