Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a lightweight, heat-resistant, sound-deadening, heat-insulating, and heat-insulating material that is lightweight and has extremely excellent fire-resistant and heat-insulating properties, and a combination of this material with high-temperature heat-resistant materials such as zircon, alumina, silica, and ceramics, and an adhesive. A lightweight, heat-resistant, chemical-resistant, sound-deadening, heat-insulating, heat-retaining material made by further mixing a mixture of various inorganic and organic heat-resistant adhesives, and then applying a high temperature above the melting point to the surface formed by molding the above substances to melt the surface.1 The present invention relates to ceramic decorative laminates and the like that can be produced after cooling, and particularly to adhesives therefor.

In the past, there were refractories made by mixing IJJ umami into lightweight insulation materials, but although sodium silicate is heat resistant, it is not water resistant (and does not melt when exposed to moisture, steam, or water). Because it was destroyed, its range of use was limited, and it could not be used outdoors.

The present invention eliminates these drawbacks, and adds acrylic resin and/or polyester resin to sodium silicate to increase water and chemical resistance. It is used to produce insulation, sound deadening, and heat retention materials.

Any adhesive polymer compound can be used for the sodium silicate adhesive used in the present invention, and acrylic resins and polyester resins are preferably used.

For mixtures of sodium silicate and acrylic resins or Fi polyester resins, etc., if the proportion of sodium silicate is reduced, the water and chemical resistance will increase but the heat resistance will decrease. The formulation is changed.

The blending ratio is 95 to 20q6 silicic anhydride to 1 part acrylic resin.
5q6~80%, 95~20% silicic anhydride, 5~80% ester resin, and 95~80% sodium silicate.
% to 20% acrylic resin 3 to 70% or acrylic resin 3 to 70%, or sodium silicate and a polymeric adhesive such as starch, silicon, or vinyl acetate may be blended.

When using the adhesive of the present invention, for example, vermiculite powder is mixed with 80% sodium silicate and 15% to 20% thiacrylic resin.
17 Mix polyester resin with engine and other combustion equipment and yl? If this is used as a heat insulator for tiller and other exhaust gas and steam, and it is applied by applying lath to the surface of an engine muffler and spraying it from the outside, the uncoated part will become red hot within an hour after the engine starts, reaching a temperature of around 400tZ'. Even if you touch the covered part with your fingertips, you will only feel the heat and will not get burned. Also sodium silicate 80~
60 Thiacrylic resin 15% to 25% and polyester resin 5% 15% When mixed at various blending ratios to make molded products or sprayed on walls, etc., the product will not lose heat resistance. Extremely chemical resistant, water resistant, heat resistant, sound deadening, heat insulating,
Water-resistant, heat-retaining, and anti-condensation materials can be obtained.

The present invention can be used freely by mixing adhesives that are soluble in either water-soluble or volatile adhesives, and even when constructing a plant in a remote location, it can be used in a formwork at a factory like conventional products. There is no need to transport products that have been steamed or baked in a drying oven to a remote location during pouring.

Example (1) Acrylic resin (Mitsui Toatsu Almartex L-1042) 2 Of was added to 60 f of silicate soda, and 50 to 80 f of water was added to this and stirred, and the inorganic pearlite sor, vermiculite 70 f, @Calcium acid 502 was mixed, then water 301 was added, mixed well, stirred, and formed into a plate.The thermal conductivity was measured after drying and was 0.03. Even if I applied heat of 3600C to the surface of the board for 1 minute, the surface of the board melted into a deep red color to a depth of about 3wi, but when I cooled it with air, it became like a ceramic, and even when I pressed the periphery or the opposite side 1crn away with my finger, it melted. I didn't feel the slightest bit of heat.

Example (2) 20 f of acrylic resin (Mitsui Toatsu Alumatex L-1060) was added to 6 Of of silicate soda, and 50 t of water was added to this and stirred, and inorganic pearlite 50 was added.
1. Add 302 ml of water to the mixture of 150 f of vermiculite and mix well (mix, stir, form into a plate, dry thoroughly, heat the surface with a burner to dissolve the surface, and then leave it. However, the surface became green lava-like.This could be used as a ceramic decorative board in various fields.

By using the adhesive of the present invention, materials can be procured locally, mixed in a mixer to a suitable viscosity, and the work can be completed by pouring with a trowel, spade, pouring vacuum, etc., or by just spraying. As a result, the construction cost is low and the construction is easy.The melting point is over 1400t:', the thermal conductivity is 0.03°, and the specific gravity is 0.3 to 0.6.As it is an inorganic material, it does not undergo corrosion or deterioration. There is no need to worry about mold growth or insect damage.
In addition, it has extremely cold resistance, soundproofing, heat retention, and sound deadening effects (therefore, it can be used as interior and exterior materials for various structures, heat insulation materials, soundproofing, sound absorbing, and sound deadening materials, fireproofing, heatproofing materials, dew condensation prevention materials, or ceramic decorative boards. It is very convenient. Applications include heat retention, heat insulation, heat resistance, fire prevention, soundproofing, sound absorption, sound deadening, and prevention of condensation, as well as for ships.

When sprayed between the inside and lining of the exterior panels of automobiles, trains, trains, aircraft, etc., it has effects such as heat resistance, fire prevention, insulation, condensation prevention, and heat retention, and can also be used on the lining of refrigerators, air conditioning equipment, etc. Interior and exterior of houses, furniture, archives, safes, Russian cars, etc., and steel frames.

It can be used for the exterior of heavy oil tanks, gasoline tanks, pipelines, cooling water, water and steam piping, etc., as well as for noise reduction equipment, to improve soundproofing and silencing effects. In addition to being used as building materials for houses as ceramic and decorative boards, they are also effective as equipment for solar houses, fireproof coatings for steel frames for high-rise buildings, and insulation materials for marine and space development bases, etc., and are also effective in preventing fires. When the fire is extinguished, only black soot adheres to the surface, and no smoke or toxic gas is emitted.
