Abstract
The present invention relates to coating composition,, proportion, at normal temperatures and pressures, form a kind of powdery thermal insulation coatings through mixing and stirring with the organic chemistry polymkeric substance mainly by selected silicate minerals, the light body inorganic mineral of multiple high-quality.Its unit weight is 1/4 of pasty state thermal insulation coatings, at a distance, when transporting in enormous quantities, can save transportation and storage cost at double.Can directly reconcile into a kind of thickness fiber pasty state lotion that does not have layering, no glue clump during use, have plasticity-and cohesive force, thermal conductivity is low, can be heat insulation, can be exhausted cold, dustless, nontoxic, pollution-free, overlay approaches, consumption is little, pipeline, valve and kiln, kiln, boiler, the equipment etc. that are widely used in industries such as chemical industry, metallurgy, electric power are located as heat insulation, lagging material.
Description
The present invention relates to coating composition, can before construction, concoct the powdered hydrophobic compound silicate insulating paint and the production method of loosening at any time for a kind of.
The lagging material that China is traditional, as asbestos, vermiculite, mineral wool, perlite etc. and goods thereof, general density is big, thermal conductivity is high; The also contaminate environment that has, be harmful to health; The temperature tolerance that has is poor, and materials are thick, and required subsidiary material are many, construction inconvenience, time-consuming taking a lot of work.Especially to special-shaped equipment such as lock, valve, dead angle, rotator, spheroid, hang difficult construction part such as face by the feet, insulation is difficulty very, makes the enterprise energy consumption that has these equipment high; Gapped between thermal insulation layer that has and the equipment dignity, water-absorbent is big, and heat insulation effect is not good.All kinds of composite silicate thermal insulation paints of Wen Shiing in recent years, though compare with traditional lagging material and to have many advantages, but because the product that its wet process technique is produced all is thick-pasty slurries when dispatching from the factory, its moisture content weight accounts for more than three times of working substance weight; Store in enormous quantities, remote shipping and producer and bring great inconvenience, also increased a large amount of transportations, storage cost simultaneously; The production technique that has is also complicated.
The present invention is the weak point that exists in above prior art, and provide a kind of hydrophobic, cost is low, fire prevention, efficient lightweight and be convenient to the thermal insulation coatings of new generation that transports, store and a kind of easy, need not immersion, the special manufacture method of slurrying, froth breaking.
The present invention is achieved in that
This dry powder insulation paint by selected silicate be the light body inorganic mineral of major ingredient, multiple high-quality be auxiliary material and with an amount of organic polymer, suspension thickening thing at normal temperatures, mixing and stirring forms under the normal pressure.
The present invention has changed present heating and warm therapy production technique that do not heat, and adopts the dry technology for production under normal temperature, the normal pressure.
Produce 1m
3The composition of hydrophobic insulating paint of compound dry powder desired raw material, component, proportioning
The selected major ingredient of the present invention is asbestos wool, sepiolite, glass microballon; Auxiliary material is perlite, aluminum silicate fiber; Organic polymer is a polyacrylamide; Suspension thickening thing is a dry powder.Be for raw material 1-7 number and easily purchase raw material on the market.
In raw materials used, at first adopted the dry powder-time play the suspension thickening power in blending.
With 1-7 raw material in the above-mentioned table, after the metering, drop into successively in the mixing tank in proportion, under normal temperature, condition of normal pressure, fully stir, make its uniformity.
The using method of this hydrophobic insulating paint of compound dry powder:
Before the construction, under normal temperature, normal pressure situation, use 1m
3Hydrophobic insulating paint of compound dry powder add the debonding agent of 15kg and the water of 750kg, stir, become no layering, do not have the thickness fiber pasty state lotion thermal insulation coatings of gummed, then construct: it is coated with (brush) to the coated article surface.
The composition of said 15kg debonding agent, component are:
A, 901 high-temp glue (liquid state), 8-10kg
B, fast penetrant T (fast T, liquid state) 7-5kg.
According to a, b adds in proper order.
Said its pasty state lotion thermal insulation coatings is in the mixing vessel of a constant volume, adds 750kg water → 1m
3Dry powder paint → begin stirs → 901 high-temp glue → fast T → till stirring.
This hydrophobic insulating paint of compound dry powder, study successfully after, it is as follows that closed test, specialized department test its physical and chemical index:

Degree of surging 98.3%
Smooth, the no bubble of visual appearance coatingsurface, nothing cracking
Concrete constructional method
(1) impurity such as the dust on removing coated article surface, rust, greasy dirt;
(2) by every m
3Hydrophobic insulating paint of compound dry powder adds the 15kg debonding agent, and the ratio of 750kg water stirs into uniform pasty state lotion;
(3) longitude and latitude intersects, and play (the first layer is coated with 1-2mm, and it is thick that the second layer is coated with 5-10mm) is successively smeared or be coated with to its pasty state lotion.
Positively effect of the present invention:
1, the wet production of prior art is changed into dry production, and technical process is short, work efficiency is high, equipment is simple, cost is low.
2, provide a kind of novel hydrophobic insulating paint of compound dry powder that can be in harmonious proportion at any time at the construction field (site); Compare with the coating of existing wet production, this coating has brought very big facility for transportation and storage, can reduce trucking costs more than 3 times, is in enormous quantities, remote transport saving substantial contribution, and product is convenient to deposit with long time stored.
3, this thermal insulation coatings has unique plasticity-, water-repellancy and cohesive force, has solved the whole dope layer insulation that the thermal insulation layer waterproof also can realize special-shaped equipment, rotator, spheroid, hang equipment such as face by the feet.Closed porosity and filamentary structure that its coating forms have certain elasticity, can and by expand with heat and contract with cold " synchronously " of automatic doubler surface glouer, have do not ftracture, wrinkle resistant, indeformable, adeciduate characteristics, reach work-ing life more than 5 years.
4, light, the good heat insulating of low, the dry unit weight of thermal conductivity (dry density), energy-saving effect are remarkable.
