Background technology
At present, the application of China aspect the building construction energy-saving heat preserving is also also few, lagging material is not adopted in most of building construction, start with from external wall and existing lagging material and technology are also many, be generally the sheet material lagging material, the time need add fixation means such as binding agent or bar frame in construction, phenomenons such as causing the construction cost height, come off easily, the surface very easily cracks, heat-insulating property is poor, waterproof is bad.
Summary of the invention
For overcoming the deficiencies in the prior art, the invention provides a kind of energy-saving house heat-insulating material.After this house heat-insulating material is used not only easy construction simple, reduce construction cost, shorten construction period, and high insulating effect, nontoxic, tasteless, pollution-free, production process is simple, and belongs to silicate series together with material of construction, with the natural muddy one-tenth of building structure, aging synchronously, the life-span is permanent.
The present invention is by 40 kilograms of sepiolites, 40 kilograms of nemalites, and 70 kilograms of high strength gypsums, 10 kilograms of No. 425 cement, 10 kilograms of tackiness agents, 10 kilograms of whipping agents, 90 kilograms of hydrophobic pearlites mix together, and outward appearance is the dry powder fiber shape that looses.During construction, this house heat-insulating material is added the suitable quantity of water stirring be the pasty state of similar sand-cement slurry, adopt conventional bricklayer, exterior wall or the interior wall that dauber worker's method directly is put on building construction, smear one deck cement mortar solidification again on its surface after doing and get final product with certain thickness.
The present invention owing to only various raw materials need be stirred in proportion gets final product, thus process very convenient, and low processing cost.Because the composition of raw materials that adopts is the environment-friendly materials of nontoxic pollution-free, institute is so that the present invention is environmentally friendly.Because the present invention adopts high strength gypsum and hydrophobic pearlite, makes the present invention have certain waterproof effect and intensity height.Thermal conductivity of the present invention is 0.056W/m.K (22 ℃), volumetric shrinkage is 2.1%, make the present invention have heat preservation and energy conservation effects efficiently, volumetric shrinkage is extremely low, and quick solidifying, resist intensity height, cohesive strength greatly, not efflorescence, do not chap, not hollowing, do not come off, frost-free.
The present invention, made and has reduced construction cost by easy construction of the present invention, the shortening construction period owing to only need add water and stir to smear in surface of wall then and get final product in when construction.
Embodiment
With 40 kilograms of sepiolites, 40 kilograms of nemalites, 70 kilograms of high strength gypsums, 10 kilograms of No. 425 cement, 10 kilograms of tackiness agents, 10 kilograms of whipping agents, 90 kilograms of hydrophobic pearlite mixing and stirring, adding suitable quantity of water restir becomes the pasty state of similar sand-cement slurry, then by conventional bricklayer, dauber worker's method is directly smeared the exterior wall in building construction, interior wall, the roof, and reach certain thickness (according to the climate temperature difference of building construction locality, the corresponding difference of thickness, be advisable for northern area 4-5 centimetre, be advisable for southern area 2-3 centimetre), can reach heat insulating effect through smearing one deck sand-cement slurry more in the above after the curing in 12 hours.
