Abstract
The invention discloses a silicate thermal insulation coating and a preparation method thereof, and belongs to the coating field; the silicate thermal insulation coating comprises the following components by weight: 20-35 parts of sepiolite, 8-15 parts of diatomite, 20-30 parts of silicate cement, 20-35 parts of methyl cellulose, 3-8 parts of calcium oxide, 3-6 parts of sodium fluosilicate, 3-6 parts of sec-octyl alcohol, 1-5 parts of aluminum hydroxide, 10-30 parts of organosilicone resin, and 30-45 parts of distilled water. The silicate thermal insulation coating has the achieved beneficial effects that: (1) the thermal conductivity coefficient is low, and the thermal insulation effect is remarkable; (2) the silicate thermal insulation coating can be in comprehensive bonding with a base face, is strong in integrality, and is especially suitable for replacing a thermal insulation material to solve special-shape equipment thermal insulation which is difficultly solved by the thermal insulation material; (3) the silicate thermal insulation coating is light in mass and thin in layers, and relatively improves the residential use area when used in building internal thermal insulation; and (4) the silicate thermal insulation coating is good in flame retardancy and strong in environmental protection.
Description
Technical field
The invention belongs to paint field, be specifically related to a kind of silicate thermal insulation coatings and preparation method thereof.
Background technology
Compound silicate insulating paint is current application thermal insulation coatings the most widely.This kind of thermal insulation coatings, at first using the sepiolite of loosening as main raw material, is main cakingagent with water glass.Afterwards except sepiolite, also added a large amount of pearlstones, expanded vermiculite, drift pearl, flyash, diatomite, asbestos, glass wool, mineral wool, aluminum silicate fiber etc.; Cakingagent used also develops into the compound uses such as gypsum (normal temperature), cement (normal temperature), high-alumina cement (middle temperature), silicon sol (high temperature) by single water glass.In addition, also coating property is improved, as mobility, hardening, hydrophobic nature, high thermal resistance, reflectivity etc. by adding various admixture.Paste thermal insulation coatings is made through techniques such as machinery making beating, foaming, stirrings.
Along with the raising of people's lives level and China instruct for the policy of building heat preserving energy conservation, thermal insulation coatings will more for the heat insulating of inner wall of building.In recent years, compound silicate insulating paint obtains the use of accreditation progressively and larger area for building inside holding, but still there is the defect that the problem that waits to solve and own material structure bring.Main manifestations is: (1) is long for drying cycle, construction by season and weather effect large; (2) impact resistance is weak; (3) large in dry contraction, rate of moisture absorption is large; (4) on the low side to the cohesive strength of body of wall, construction wrong easily causes big area hollowing phenomenon; (5) ornamentally further improvement is awaited, etc.Therefore, the technical superiority that China is acquired in this respect should be made full use of, exert to improve the over-all properties of this type of coating, make it for building heat insulation.
Summary of the invention
In order to overcome the above problems, the invention provides a kind of silicate thermal insulation coatings and preparation method thereof.
A kind of silicate thermal insulation coatings, comprises following components by weight percent: sepiolite 20-35 part, diatomite 8-15 part, silicate cement 20-30 part, methylcellulose gum 20-35 part, calcium oxide 3-8 part, Sodium Silicofluoride 3-6 part, sec-octyl alcohol 3-6 part, aluminium hydroxide 1-5 part, silicone resin 10-30 part, distilled water 30-45 part.
Further, described silicate thermal insulation coatings, comprises following components by weight percent: sepiolite 30-35 part, diatomite 10-15 part, silicate cement 25-30 part, methylcellulose gum 30-35 part, calcium oxide 5-8 part, Sodium Silicofluoride 3-6 part, sec-octyl alcohol 5-6 part, aluminium hydroxide 3-5 part, silicone resin 20-30 part, distilled water 35-45 part.
Prepare a method for described silicate thermal insulation coatings, said method comprising the steps of:
All use sieve sieved to various raw material, first diatomite, methylcellulose gum, sepiolite, silicate cement are mixed, add water and silicone resin again, agitator stirs half hour, then sec-octyl alcohol froth breaking is added, add calcium oxide, Sodium Silicofluoride, aluminium hydroxide after batching is left standstill 5-10 hour again, be uniformly mixed and obtain described silicate thermal insulation coatings.
Thermal insulation coatings is the thick shape lotion of fiber, it combines the dual characteristics of coating and lagging material, the loss of heat can be reduced, it is spread upon the equipment pipe or building surface that require insulation, some strength and elastic thermal insulation layer is formed after drying, equipment operation or vibrations all can not be ftractureed and be come off, and buildings can reach decoration and warming double effects; From heavy and light, high insulating effect, meanwhile, water-absorbent is little, and lower temperature resistance is good, and resistance to acids and bases is better.
The beneficial effect that the present invention reaches is: described thermal insulation coatings combines the dual nature of coating and lagging material, compared with Conventional insulation, has the following advantages: (1) thermal conductivity is low, and heat insulation effect is remarkable; (2) can cohere with basal plane, globality is strong, is specially adapted to the insoluble special-shaped insulation of equipment of alternative lagging material comprehensively; (3) light weight, layer are thin, are used in building inside holding and relatively improve residential usage area; (4) good flame resistance, the feature of environmental protection is strong; (5) construction is relatively simple, and the mode of manually smearing can be adopted to carry out; (6) material producing process is simple, and energy consumption is low.
