Abstract

The invention discloses an insulation wall body integral-casting material and a construction method thereof. The insulation wall body integral-casting material is characterized in that the ratio of a binder, an insulation aggregate and an additive is 1000:(5-5000):(0-300); the binder is a cement-based binder or a gypsum-based binder; the constitutes of the cement-based binder are 300-1000 parts of cement, 0-200 parts of silica fume, 0-400 parts of fly ash, 0-700 parts of slag powder, 0-300 parts of zeolite powder, 0-200 parts of ash-calcium powder and 0-40 parts of gypsum; the constituent of the gypsum-based binder is 1000 parts of gypsum; and the constituents of the insulation aggregate are 0-100 parts of expanded polystyrene granules, 0-1500 parts of expanded perlite, 0-1500 parts of expanded vermiculite, 0-1500 parts of expanded vitrified microspheres, 0-5000 parts of expanded ceramisite and 0-200 parts of sepiolite fibers. The invention also comprises the construction method. The wall bodies casted by the insulation wall body material have good insulating and thermal performances, higher strength, and good water resistance, crack resistance and permeability resistance performances, as well as good compatibility and good security towards the subsequent decorating process.

[0002] At present, the methods for thermal insulation of walls mainly include the following three categories: (1), attaching other thermal insulation materials to the outside or inside of the usual masonry wall, and the thermal insulation material can be thermal insulation mortar constructed by plastering process , It can also be various forms of thermal insulation boards constructed by pasting technology. They are currently the thermal insulation wall materials with the highest market share. The advantage of this type of product is lower cost; The difficulty is high. The strength of most of these products is below 0.3MPa, and the softening coefficient is low. After contact with water, the strength will drop significantly, and the thermal insulation performance will also drop significantly. In this type of project, tiles and stones will fall off and hurt people. Incidents are often seen in the newspapers, and its fire performance is also controversial in the construction engineering field; (2) The thermal insulation and decoration integrated panels that integrate thermal insulation and decorative functions are basically fixed by steel frames or similar mechanical installations On the outside of the building wall, this type of product has the advantage of good thermal insulation performance, but the disadvantage is that the cost is much higher than that of the (1) type of product, and it is only suitable for the insulation and decoration of a few high-end buildings. In China's existing economic conditions Such products will only serve as a minority in the field of building thermal insulation and energy saving for a long time; (3) use air expansion or increase the hollow rate of the block, or further fill the hollow part of the block with insulation materials to Reduce the density and thermal conductivity of the block itself, and then use this type of block to build a wall with thermal insulation performance. Among these products, the aerated block has better thermal insulation performance, but its strength is low and the water absorption rate is too high. , it is easy to cause the hollowing, cracking, falling off and water seepage of the decorative layer in the follow-up process.

Hollow products have good strength and no problem with water absorption, but the thermal insulation performance is difficult to meet the requirements. In relation to the situation that the country has higher and higher requirements for building energy conservation in the future, the technical problems of thermal insulation performance of this type of product have yet to be overcome.

[0003] CN 98207105 Chinese patent application discloses a prefabricated thermal insulation wallboard with a glass fiber mesh and anti-cracking mortar protective layer. Due to the large size of the wallboard, it is inconvenient to load, unload, hoist and transport, and the manufacturing process of the wallboard is relatively cumbersome. And although there are anti-crack measures in the gaps between the wall panels, there are still risks of cracking and water seepage

[0004] CN 2000610010495.1 Chinese patent application discloses a light-weight energy-saving thermal insulation wall material, which contains 22-26% sand. The product is a block with low compressive strength and a large difference in strength from subsequent process materials. And because it is a non-integral pouring material, there is a hidden danger of cracking in the joints of the block masonry, and once cracked, it will affect its anti-seepage and thermal insulation performance
