Construction technology feature simple, high efficiency, can be widely applied to the various major-minor equipment of the high temperature needing to take Insulation and pipe
Road outer surface insulation.
Technical scheme
It is an object of the invention to be achieved by the following measures:
A kind of high-performance energy-saving heat-insulating material, is made up of the raw material of following weight portion: water 400-500 part, crushed crude pearlite 200-
250 parts, sodium silicate 10-20 part, aluminium silicate wool 30-40 part, sepiolite powder 10-30 part, white clay powder 0.1-0.5 part, bentonite
0.1-0.3 part, ripe rubber powder I 0.3-0.7 part, ripe rubber powder II 0.1-0.5 part, cellulose 0.3-0.7 part, foaming agent 2-5 part, resistance
Combustion agent 1-10 part, polyacrylamide 0.3-0.7 part, polyvinyl alcohol 0.1-0.5 part, aluminum phosphate 0.1-0.5 part.
Preferably, described high-performance energy-saving heat-insulating material is made up of the raw material of following weight portion: 450 parts of water, crushed crude pearlite 220
Part, sodium silicate 15 parts, aluminium silicate wool 35 parts, sepiolite powder 20 parts, 0.3 part of white clay powder, bentonite 0.2 part, ripe rubber powder I 0.5
Part, ripe rubber powder II 0.3 part, cellulose 0.5 part, foaming agent 3 parts, fire retardant 8 parts, Polyacrylamide Powder 0.5 part, polyethylene
0.3 part of alcohol powder, aluminum phosphate 0.3 part.
Wherein, ripe rubber powder is the one of carboxymethyl starch, is made up, outward through carboxy methylation, crosslinking, ripe gel of native starch
Shape is irregular tablet, has instant capacity and high viscosity, is novel architecture high performance adhesive.Ripe rubber powder I is for being applicable to
The additive of various dry-mixed mortars, ripe rubber powder II is the additive being applicable to water-resistant putty for interior wall.
Meerschaum is the rich magnesium silicate clay mineral of a kind of threadiness, has extremely strong absorption property and sealing property.
Foaming agent can increase the content of gas in insulation material, thus strengthens the effect of insulation.
Described foaming agent may select isocyanates, and ultimate principle is that isocyanates discharges CO with water generation chemical reaction2,
CO2Play foaming effect.
The example of described isocyanates includes toluene di-isocyanate(TDI) (TDI), methyl diphenylene diisocyanate (MDI)
Deng.
Fire retardant can improve fire resistance and the heat stability of insulation material.
In parts by weight, described fire retardant comprises: 22 parts of octabromodiphenyl base ethane, antimony oxide 15 parts, triphenyl phosphorus
Acid esters 8 parts.
Described fire retardant can be prepared via a method which: by octabromodiphenyl base ethane, antimony oxide and triphenyl phosphorus
Acid esters is sufficiently mixed in mixer, obtains described fire retardant.
Octabromodiphenyl base ethane and antimony oxide are used together and can strengthen flame retardant effect.Triphenyl can carry
The heat stability of high insulation material.
Present invention also offers a kind of method preparing high-performance energy-saving heat-insulating material, including:
(1) aluminium silicate wool and cellulose are added to the water, soak 30-50 hour；
(2) soak of step (1) is joined in eddy current type agitator, be sufficiently stirred for 1-2 hour, become flakes；
(3) add Polyacrylamide Powder, continue stirring 0.5-1 hour；
(4) aluminum phosphate, sodium silicate, sepiolite powder, white clay powder, bentonite, ripe rubber powder I, ripe rubber powder II, fire-retardant it is sequentially added into
Agent, continues to stir into mastic；
(5) being gradually added crushed crude pearlite, pva powder, foaming agent, be sufficiently stirred for, mastic is mixed expanded；
(6) mastic after expanding is divided in hermetic container；Or the mastic after expanding is poured into add in mould and is pressed into
Type, is then dried into efficient energy-saving heat-preservation section bar.
Wherein, in step (1), aluminium silicate wool adds cellulose and can shorten soak time, and soften aluminium silicate
Cotton.
In step (6), the mastic after expanding weighs immediately and is divided in hermetic container, wants mastic in time behind Kaifeng
Applying material is on the equipment that need to be incubated；Or the mastic after expanding pours extrusion forming in mould into, is dried into energy-efficient
Heat-insulating profile, is directly wrapped in heat-insulating profile during use or mats formation on the equipment needing insulation.
The paste high-performance energy-saving heat-insulating material being saved in hermetic container, wanting behind Kaifeng to be spread upon by ointment material in time needs
On the equipment of insulation, to prevent the air in material the most excessive.If desired after dry tack free, repaste one layer of solidification layer, to add
Strong surface strength, prevents jarring damaged.
Construction method: draw the gross thickness of optimal heat-insulation layer according to medium temperature, is first coated with ground floor, and ground floor thickness is general
Be 20～30mm, after ground floor degree of drying reaches about 90%, repaste the second layer, the like until reaching required guarantor
Temperature thickness.
The heat-resisting ability of the insulation material of the present invention can reach more than 1000 DEG C, and unit weight is 150～180kg/m3, attachment
Power is strong, all can wrap up firmly under complicated face shaping.
Beneficial effect
The insulation material good heat-insulation effect of the present invention, and there is the strongest resistance to elevated temperatures and fire resistance；Heat conductivity
Low, ability of pasting is strong, and acid and alkali-resistance is nontoxic dustless pollution-free.
The insulation material of the present invention is mastic, and privileged sites narrow at pipeline can use, and only needs common bricklayer
The most operable, construction is simple, greatly improves efficiency of construction.
The outer surface that the composite can be widely applied to the various major-minor equipment of the high temperature needing to take Insulation and pipeline is protected
Temperature, it is possible to form the most seamless complete heat-insulation layer, amplitude peak ground reduces radiation loss, drastically increases heat energy utilization
Rate, improves heat-insulating property.
Processing technique is simple, it is not necessary to add the heat loss energy, it is not necessary to stands, shortens preparation time.
The present invention can be processed at scene, decreases freight, the most nonflammable, and non-hazardous does not chaps, and is difficult to
Air slaking come off, and the discarded insulation material removed can reuse, effectively save resource.
