Description

Non-bearing sintering class composite heat insulation block

Technical field:

The present invention relates to building energy saving field, especially a kind of non-bearing sintering class composite heat insulation block.

Background technology:

Exterior wall on the present construction market and the masonry position that need be incubated, insulation is main beyond many, main organic class of material and mineral-type two classes used, wherein organic class comprises: expanded polystyrene (EPS) (EPS), extruded polystyrene (XPS) and polyurethane foam (PU), mineral-type comprises: the slurry of preserving moisture includes perlite etc.A small amount of non-load-bearing concrete composite insulating brick that uses, its way is for partly to insert glue powder polyphenyl particle, EPS plate, XPS plate and foam cement etc. at the concrete hollow block cavity.

Though the material of the organic class of external wall outer insulation has advantages such as material is light, coefficient of thermal conductivity is low, but its flammable shortcoming makes the people be subjected to great injury, as: China Science and Technology Hall's big fire in 2009, CCTV's big fire, Shanghai big fire in 2010, Shenyang big fire in 2011 etc., it is short that this class organic insulation material has service life simultaneously, can not with the same life-span of agent structure, and can discharge pernicious gas when aging and cause air environmental pollution.

Although mineral-type exterior-wall heat insulation class can reach the requirement of combustibility A level, heat-insulating property is relatively poor, and is easy to crack, come off, and finally aggravated the deterioration of heat-insulating property, can not with the same life-span of agent structure, and can bring potential safety hazard.

Though people have recognized the defective of above two class exterior-wall heat insulations, developed coagulation great soil group composite thermal self-insulation building block, but because the carrier that choosing has is the building-block of coagulation great soil group, it is big that this material has a coefficient of thermal conductivity, the unit weight height, form behind the masonry easy to crack, and in to be filled with the organizational security adiabator easily aging, can not with main body with the life-span and meet the moist back moisture content defectives such as reducing heat insulation effect slowly of scattering and disappearing.

Summary of the invention:

In order to overcome the above-mentioned technical problem that existing product exists, the invention provides a kind of new product that can substitute above product, thereby reach exterior wall and need the masonry position heat-insulating property of insulation excellent, fire-protection rating is non-combustible component (being better than the A level) and with the same life-span of agent structure, masonry does not ftracture, the body of wall rendering layer non-bearing sintering class composite heat insulation block of advantage such as do not come off.

The present invention is achieved through the following technical solutions its goal of the invention.

Non-bearing sintering class composite heat insulation block is made of building-block and the high heat insulating material of mineral-type, it is characterized in that, inserts the high heat insulating material of mineral-type and constitute non-bearing sintering class insulation blocks in the cavity of building-block.

Described building-block is to be mixed the small amount of clay sintering and formed by gangue class, shale class, flyash, and wherein, the content of gangue class, shale class, flyash accounts for 95%, the content 5% of clay, and sintering temperature is between 900 ℃-1250 ℃.This carrier has the intensity height, unit weight is light, deformation is little, forming masonry with cement mortar combines firmly, with the same life-span of agent structure, the material coefficient of thermal conductivity is little, " breathing " function of good heat inertia index and good adjusting building indoor environment humidity and " phase shift " function of balance indoor and outdoor peak temperature.

The high heat insulating material of described mineral-type is to add the blowhole forming agent after the inorganic high heat preserving and insulating material that sclerosis forms by cement-based material, its percentage composition is: cement 70-95%, flyash 2-25%, silica flour 1-5%, the blowing agent that adds blowing agent 0.8-1.5%, adopt the special-purpose stirring of foam concrete, foaming, mix, carry all-in-one (patent No. ZL201020163509.5), closed porosity inorganic material by the back formation foam cement that stirs, foams, mixes, carries, hardens, coefficient of thermal conductivity is low after this hardened material moulding, and unit weight is light.

Non-bearing sintering class composite heat insulation block of the present invention, its preparation technology is:

1, wherein a kind of of gangue class, shale class, flyash or several are mixed 5% vitrified bond and become hollow caking.

2, building block is come on the mould bases of bed die, the aperture makes progress, and following hole seals with bed die, prevents to pour into unhardened foam cement and flows out.

3, with cement 70-95%, flyash 2-25%, silica flour 1-5%, add blowing agent 0.8-1.5%, adopt that foam concrete special-purposely stirs, foaming, mix, carry all-in-one (patent No. ZL201020163509.5), by stir, foaming, mix, carry, closed porosity inorganic material that the sclerosis back forms foam cement.

4, will prepare the foam cement of just not doubting, pour in the cavity of building block.

5, utilize insulation or steam-cured method maintenance moulding promptly to generate this product, this product strength grade meets Mu5.0 building-block material, and unit weight is not more than 1100kg/m ³, coefficient of thermal conductivity is between 0.08W/ (mK)-0.18W/ (mK).

Technological progress of the present invention is, this product overcomes the weak point of present wall heat insulation material, reach body of wall and need the masonry position heat-insulating property of insulation excellent, fire-protection rating be non-combustible component (being better than the A level) and with the same life-span of agent structure, masonry does not ftracture, body of wall rendering layer advantage such as do not come off.

Description of drawings:

Accompanying drawing is a structural representation of the present invention.
