Description
Technical field
The invention belongs to building material technical field, especially relate to a kind of light-weight brick with the heat insulation performance of preserving moisture.
Background technology
Along with the continuous development of Building Trade in China, people require more and more higher to the feature of environmental protection of constructional materials.Originally a large amount of conventional clay of using can not satisfy " energy-conservation, joint soil " requirement in body of wall, and novel materials for walls such as concrete perforated brick, gypsum block and air-entrained concrete building block constantly occur.Because have high-strength, lightweight, save land, energy-conservation, sharp advantage such as useless, concrete small size hollow building block becomes the leading materials for wall that replaces solid clay brick at present just gradually.But along with a large amount of uses of concrete small block, problems such as the cracking seepage of blockwork also become increasingly conspicuous, and general 190mm single row of holes concrete small block wall heat transfer coefficient is about 2.78W/ (m
2.K), heat-insulating property is poor, along with the issuing and implementation of building energy-saving standard, must adopt supporting insulation measure, and the small-sized hollow building block body of wall is applied in various places.
For this reason, people have invented the outer insulation blocks [application number: 200520047043.1] of a kind of gas concrete, are to be made of concrete pellet and gas concrete layer; The concrete pellet is arranged on building block inside,, the gas concrete layer is arranged on the concrete pellet periphery of load-bearing, as the external thermal insulation of concrete pellet as load-bearing material; The concrete pellet can also can have hollow hole for solid.Not only can save China's limited land resources, also can realize the target that body of wall is energy-conservation, simultaneously, improve the application life of body of wall greatly.；
The somebody has invented a kind of high-content fly ash brick [application number: 200710011758.5], and its component is the percentage meter by weight, and it contains the wet thin ash 60～87% of flyash, low strength cement 4～13%, aggregate 9～35%, flyash additive 0.02～0.06%.The wet thin ash of flyash comprises dried ash discharge, wet ash discharge and extra large ash discharge; Aggregate is thick slag of flyash or sandstone; The flyash additive is made up of acrylic copolymer and water.After said components mixed by proportioning, shake molded and carry out the high-content fly ash brick that the short time steam curing promptly can be made into the present invention by forming machine.
Though such scheme improves to some extent to a certain extent, the manufacturing cost height, manufacture difficulty is big, is difficult to apply; And on performance, be difficult to take into account simultaneously performances such as the heat-insulating sound-insulating of preserving moisture.
Summary of the invention
The objective of the invention is at the problems referred to above, provide a kind of compatibility reasonable, have the heat insulation performance of preserving moisture simultaneously concurrently, be easy to processing and manufacturing, and lower-cost light-weight brick with the heat insulation performance of preserving moisture.
For achieving the above object, the present invention has adopted following technical proposal: originally have the light-weight brick of the heat insulation performance of preserving moisture, it is block that this light-weight brick is, and it is characterized in that component and parts by weight thereof that this light-weight brick comprises are respectively:
Parts by weight are the cement of 300-700; Parts by weight are the flyash of 50-200; Parts by weight are the cellulose ether of 0-8; Parts by weight are the thixotropic agent of 0-3; Parts by weight are the crushed crude pearlite of 100-700.
The macromolecular compound that cellulose ether is made by cellulose with ether structure.Each glucose basic ring contains three hydroxyls in the cellulose macromolecule, and the secondary hydroxyl on the primary hydroxyl on the 6th carbon atom, second and third carbon atom, the hydrogen in the hydroxyl are replaced by alkyl and generate the cellulose ether analog derivative.It is the product that the hydrogen of hydroxyl in the cellulose macromolecule is replaced by alkyl.Cellulose is the also polyhydroxy macromolecular compound of not fusion of a kind of neither dissolving.Cellulose then can be water-soluble after etherificate, dilute alkaline soln and organic solvent, and have thermoplasticity.Cellulose dissolution performance generation marked change after etherificate is dissolvable in water water, diluted acid, diluted alkaline or organic solvent.Thixotropic agent can form the material of the bigger serface of hydrogen bond or certain other structures with polymer; Stressed thinning, leave standstill retrogradation.
In the above-mentioned light-weight brick with the heat insulation performance of preserving moisture, the optimization component and the parts by weight thereof of this light-weight brick are respectively:
Parts by weight are the cement of 550-650; Parts by weight are the flyash of 100-150; Parts by weight are the cellulose ether of 4-6; Parts by weight are the thixotropic agent of 1-2; Parts by weight are the crushed crude pearlite of 400-600.
In the above-mentioned light-weight brick with the heat insulation performance of preserving moisture, the granularity of described crushed crude pearlite is 0.1mm-3.0mm.
In the above-mentioned light-weight brick with the heat insulation performance of preserving moisture, described thixotropic agent is any one or the multiple combination in polyamide wax, silica, organobentonite, asbestos, kaolin, attapulgite, the emulsion method vinyl chloride compound.
In the above-mentioned light-weight brick with the heat insulation performance of preserving moisture, described cement is No. 42.5 portland cements.
Compared with prior art, the advantage that originally has the light-weight brick of the heat insulation performance of preserving moisture is: 1, have the higher heat insulation performance of preserving moisture, can be widely used in building trade, be specially adapted to building by laying bricks or stones of non-bearing wall body.2, be easy to processing and manufacturing, low production cost.
