Description
Technical field
The present invention relates to field of heat insulating materials, more particularly to building thermal insulation material.
Background technology
At present, polystyrene, polyurethane and Foaming of phenolic resin material are because low density and low thermal conductivity is extensive
As building thermal insulation material.But, because they are organic materials, their non-refractories.At high temperature in use, they may
It can burn, cause the fire of fire, such as CCTV building.Therefore, develop a kind of inexpensive, fire-retardant inorganic material and be used as building
The insulation material of exterior wall is particularly important.A kind of fine perlite, light porous inorganic material is used as a kind of efficiently building
Insulation material is slowly coming into the life of people.Comprising many micron-sized holes in fine perlite, and have up to
90% porosity.Contrasted with conventional cement building materials, fine perlite has lower thermal conductivity factor and density, higher sound-absorbing
Rate, adds the fabulous fire resistance of fine perlite and higher mechanical strength, it is becoming increasingly popular in terms of Application in Building, and
It is developed rapidly.Although there are many advantages, fine perlite still has some problems, example as building thermal insulation material
Such as, it is that its thermal conductivity factor of the thermally insulating material for building of base material is sent out higher than polystyrene, polyurethane and phenolic resin using fine perlite
The building materials such as foam material.A kind of aeroge, hole nano material with high porosity, high attention is obtained in energy-conserving and environment-protective material
Today, it is considered to be most promising superthermal insulation construction material.As a kind of super insulation material, it has been used for solar energy
In terms of system, refrigerator.Compared to traditional insulation material, aeroge shows its significant characteristic, such as high surface area（ 500-
1200m2/g）, high porosity（ 80-99.8%）, low bulk density（ 0.003g/cm3）, extremely low thermal conductivity（ 0.013W/
m.K）, and acoustic characteristic（The velocity of sound is as little as 100m/s）.Due to its excellent performance, aerosil is in different fields
There are many potential applications, such as adsorbent, separation equipment, biological medicine, sensor, delivery system, catalyst carrier etc..
However, aeroge production cost is high, poor mechanical property, which greatly limits its building materials field business application.
To reduce its production cost, improve a few thing for the purpose of its mechanical strength and carried out, recycling, the life of such as solvent
The shortening in production cycle, silica aerogel/epoxy resin composite material, aerosil perforated glass pearl and silica
Aeroge/glass fiber compound material etc..But either which kind of mode, because the complexity of aeroge preparation technology, aeroge
It is still higher as heat-insulating construction material cost.
Therefore, comprehensive SiO2The splendid thermal insulating properties of aeroge and the mechanical strength of fine perlite and low cost it is excellent
Gesture, the present invention is in the SiO that adulterated in fine perlite2Aeroge, with reference to both advantages, prepares a kind of building heat preservation material
Material.
The content of the invention
To improve the heat-insulating property and mechanical strength of material, one aspect of the present invention is：One kind is provided to build
Building thermal insulation material, its composition is：Fine perlite, flyash, silicon dioxide aerosol, aluminum phosphate, carboxymethyl cellulose
Sodium, water, the composition are calculated as by weight：41 ~ 46 parts of fine perlite, 10 ~ 14 parts of flyash, silicon dioxide aerosol 10 ~ 19
Part, 7 ~ 12 parts of aluminum phosphate, 7 ~ 13 parts of sodium carboxymethylcellulose, 20 ~ 45 parts of water.
Further, the silicon dioxide aerosol is hydrophobic silica aerosol.
Further, the composition fine perlite is calculated as 45 parts by weight.
Further, the composition flyash is calculated as 12 parts by weight.
Further, the composition silicon dioxide aerosol is calculated as 17 parts by weight.
Further, the composition aluminum phosphate is calculated as 9 parts by weight.
Further, the composition aluminum phosphate is calculated as 9 parts by weight.
Further, the composition sodium carboxymethylcellulose is calculated as 11 parts by weight.
The beneficial effects of the invention are as follows：The situation of prior art is different from, the invention provides a kind of building thermal insulation material,
Good heat insulating, high mechanical strength, cost is low；The present invention uses hydrophobic aerogel, solves using conventional aeroge, gained
Product moisture effect is poor, and the moisture in exposure absorption air easy in atmosphere greatly improves thermal conductivity factor, and mechanical strength is big
It is big to weaken.And in invention, using hydrophobic silica gas as composition, the doped silica aerogels in perlite, preparing can be in tide
The wet building thermal insulation material for waiting the cost performance used under mal-condition higher.
