By the adoption of unique material compositions for reasonable matching, the mortar and the product thereof have excellent heat insulation performance as well as good anti-seeping, anti-cracking and high temperature resisting performance; the refrigerating effect and the heating effect can be improved, energy conservation and emission reduction are achieved, and the environment is protected.
Description
Technical field
The present invention relates to a kind of mortar, particularly relating to a kind of mortar for making insulation aerated bricks.
Background technology
Aerated bricks is the aerated bricks building block of being produced by autoclave at high temperature apparatus and process, and namely adopt the brick product comprising other various explained hereafter of steam pressure, its unique distinction is that it is a kind of novel building walling of very light-duty heat insulating.Aerated bricks sharpest edges economize the land resource exactly, need not waste a large amount of arable lands, and its raw material is drawn materials extensively, dust and sand, slag, and flyash and coal gangue etc. are all the starting material doing aerated bricks, after raw material is mixed into mortar, then make aerated bricks through moulding process.Slurry composition prepared by current most manufacturer and performance perfect not, cause the aerated bricks made occur low, the easy explosion of intensity, water-fast weak, insulation heat resistance difference etc. defect, its technical recipe still needs further improvement.
Summary of the invention
The present invention aim to provide a kind of for make insulation aerated bricks mortar, not only there is good heat-insulating property, and all the other performances comparatively like product also have larger improvement.
The present invention is achieved through the following technical solutions:
For making a mortar for insulation aerated bricks, be made up of the material of following weight part:

Further, to be label be described cement 42.5 and above silicate cement.
Further, described river sand by 30 ~ 50% particle diameter be 0.25 ~ 0.35mm fine sand and 50 ~ 70% particle diameter be that the medium sand of 0.35 ~ 0.50mm is formed.
Further, described slag is one or more compositions of Iron-ore Slag, magnesium slag, Copper Slag, zinc ore slag, and the particle diameter after its pulverizing is not more than 3mm.
Further, dispersibling rubber powder described in is vinyl acetate and higher aliphatic vinyl acetate copolymerization rubber powder.
Further, described modified expanded perlite be by pearlstone and polysiloxane powder with mass ratio 3:1 mix be placed on 70 ~ 90 DEG C of conditions under stir 2 ~ 3h after, then the lanthanum oxide powder adding mixture total mass 10 ~ 20% mixes.
Further, described whipping agent is one or more compositions of sodium lauryl sulphate, Sodium dodecylbenzene sulfonate, ferrous sulfate, potassium permanganate.
The present invention has following beneficial effect:
(1) pearlstone itself has good sound insulation, insulation, heat-resisting effect, but can large quantity of moisture be absorbed after chance water, its thermal conductivity can increase tens times, have a strong impact on heat insulating effect, the present invention to carry out modified to pearlstone, make the hydrophilic radical on its surface become hydrophobic group, substantially increase water resistant ability, the lanthanum trioxide of interpolation further increases its weather resistance, shock-resistant, high temperature resistant and corrosion resistant characteristic.
(2) method paulownia cone fiber is the vegetable fibre that water refused by a kind of oleophylic of light weight, there is good water resistance, the distinctive hollow structure of fiber has good insulation, heat-proof quality, its surface has small tubercle and hook thorn increases surface-area and adhesion property, unordered makes an addition to the effect can playing each component of bridge joint in mortar, further increases the intensity of mortar and goods thereof, resistance to cleavage and impervious water, thermal and insulating performance.
(3) to sum up, the present invention adopts unique material composition reasonably to arrange in pairs or groups, and imparts the thermal and insulating performance of mortar and goods excellence thereof; there is again good impervious water, cracking resistance, resistance to elevated temperatures simultaneously; can promote refrigeration and heating effect, energy-saving and emission-reduction, protect environment.
