Technical field
The invention belongs to building thermal insulation material manufacture technology fields, and in particular to a kind of strong thermal insulation foaming water of adhesive property
Mud.
Background technology
The rapid development of national economy has driven the persistently overheating of building material industry, the energy and environment as building
The problem of two mouth benefits of industry are attracted attention gradually is suggested the new requirement based on building energy conservation and environmental protection.It is but overall
Architectural design is unreasonable, and energy-saving effect is poor, uncoordinated with a series of safety prevention measure such as environment, fire prevention, seriously affects
The overall performance of building so that energy saving and environmental protection is performed practically no function, and then affects the big of entire construction industry
Development.Currently with the continuous growth of world energy sources demand, China's energy demand has also welcome peak, particularly goes in building
Industry, the benefit increase of energy demand proportion mouth, and with the beneficial improvement of living standard of the people mouthful, building energy consumption most surmounts at last
Industry etc. become the industry of energy consumption maximum in all industries.Various circles of society will higher to the cry of building energy conservation.It is protected in China
Warm heat-barrier material research starting is more early, and initial heat preserving and insulating material research is mainly concentrated on above building common used material,
Such as concrete, mortar, glass, plastics.Foam cement is by the foamed system of foaming machine that foaming agent is mechanically abundant
Foaming, and foam is uniformly mixed with cement mortar, cast-in-place construction or mould molding then are carried out by the pumping system of foaming machine,
A kind of novel light insulation material containing a large amount of sealed porositys formed through natural curing.It belongs to air bubble-shaped heat insulating material
Material, outstanding feature are that the foam hole of closing is formed in inside concrete, make concrete light and thermal insulation separation thermalization.
Due to it, slowly solidification causes the sample that foaming completes and collapses in a mold mould existing foam cement, caking property
It can be greatly reduced, presently, there are the shortcomings of thermal conductivity factor is higher, intensity is poor, unit weight is big for foam cement.
The content of the invention
The purpose of the present invention is being directed to the problem of existing, a kind of strong thermal insulation foaming cement of adhesive property is provided, significantly
Improve the adhesion strength of existing foam cement.
The present invention is achieved by the following technical solutions：
A kind of strong thermal insulation foaming cement of adhesive property, is made in parts by weight of following component：Portland cement 150-160

Sour calcium 0.7-0.9 parts, 0.3-0.5 parts of lithium carbonate, 220-240 parts of water, preparation method comprises the following steps：
（1）By flyash and perlite mixing, the water of 1.2-1.3 times of volume is added in, balling-up is mixed, is handled under microwave
After 10-20 minutes, foam, foamed time for 3-4 it is small when, when grinding 6-8 is small, grain fineness 0.02-0.03% is aqueous
Measure as 40-45%, be then sintered at 1200-1300 DEG C 10-12 it is small when, grinding obtains ceramic powder；
（2）Step is added in agitator（1）The ceramic powder being prepared and other institutes in addition to hydrogen peroxide, flake asbestos
There is raw material, add water, quickly stir evenly, flake asbestos is then added in into uniform cement slurry, it is stirring while adding, it is repeatedly a small amount of
Addition, finally, pour into hydrogen peroxide, stirred 15-20 seconds under 3000-3100 revs/min of speed, you can enter mould, foam,
It demoulds, is conserved to age after when 20-24 is small.
It is further described as to said program, the activator is by calcium hydroxide, calcium chloride, sodium sulphate, sodium metasilicate
According to 7-8:5-6:11-12:3-4 mass ratioes are prepared.
It is further described as to said program, the water-reducing agent is naphthalene water reducer.
It is further described as to said program, step（1）The ceramic powder granule size is in 10-50 microns
Between.
It is further described as to said program, step（2）The curing age is 5-7 days.
The present invention has the following advantages compared with prior art：In order to solve the problems, such as foam cement bad adhesion, the present invention
A kind of strong thermal insulation foaming cement of adhesive property is provided, ceramic powder is prepared using flyash and perlite, it is superfine
Chemical reaction occurs between haydite and cement and adds the intensity of foam cement, understands that the property of haydite is very by forming for haydite
Stable material in interface there is interfacial reaction, enhances the adhesion strength of interface, due to haydite rough surface and has
Tiny micropore can have strong Mechanical Adsorption effect, during the maintenance of product, haydite between the hydrated product of cement
Interior moisture can be slowly lost in so that and the hydrated cementitious between interface is more thorough, and reaction process carries out more complete, because
This cohesive force is more secured, while the resistance to compression of foam cement and flexural strength also have been respectively increased 15-18%, 13-15%.
