Abstract
The present invention relates to a production method of a heat insulating composite building block. The building block is composed of a hollow building block and a core body positioned in the hollow building block. Raw materials producing the core body of the building block are fly ash and Sorel cement. The fly ash and the Sorel cement of the weight percentage contents of 40% to 60% and 30% to 40% are put in a shearing type stirrer for mix and stir; when the stir, additives of the weight percentage content of 10% to 20% are added in the shearing type stirrer; the fly ash, the Sorel cement, and the additives are sufficiently stirred into gruel shape; then, the gruel-shaped material is injected in a hollow cavity of the hollow building block, naturally foamed for adhering into an integral composite building block which is naturally molded after 24 hours by natural curing and put into use after 28 days. Because the building block is composed of the core body and the hollow building block, heat insulating effects are good. By using the present invention to build a wall body, the wall body does not use heat insulating materials for obvious energy saving effects, and a thick wall of 370 can save 65% of energy by tests. The building blocks can be horizontally and vertically staggered and cut for use.
Description
Technical field
The present invention relates to a kind of construction material, specifically a kind of production method of heat insulating composite building block.
Background technology
At present, the hollow brick goods that building industry is used, the load bearing wall, filled wall and the rural area China Democratic National Construction Association dwelling house bearing wall that are mainly used in building use, and this brick has the shockproof effect of light body, and its weak point is that heat insulation effect is poor, easy to crackly leaks out, leaks.
Summary of the invention
The technical problem to be solved in the present invention is the shortcoming at prior art, and a kind of high insulating effect is provided, the production method of sturdy and durable indehiscent heat insulating composite building block brick.
Solve the problems of the technologies described above by the following technical solutions:
A kind of production method of heat insulating composite building block, described building block is made up of building-block and the core body that is positioned at building-block, and the raw material of production building block core body is flyash and Sorel cement, it is characterized in that,
A, production stage are: be earlier that 40%～60% flyash, 30%～40% Sorel cement are put into shearing stirrer for mixing stirring with weight percent content, when stirring, the interpolation weight percent content is 10%～20% flyash excitant in the past shearing mixer, and the three is fully stirred into congee shape material;
B, in congee shape material, add 6% blowing agent by weight;
C, then congee shape material is poured in the cavity of building-block, bonding being integral of natural foaming made composite block;
D, composite block is placed on natural curing under 5 ℃～25 ℃ the environment, natural moulding after 24 hours was come into operation after 28 days.
After adopting technique scheme, compared with prior art, the present invention has following useful effect: because high insulating effect is made of in building block core body and building-block.Use the present invention's body of building a wall, body of wall can it goes without doing inside and outside insulation, energy-saving effect is remarkable, after testing, 370 thick wall can save energy 65%.This building block can interlock anyhow to cut and use.The cement foamed formation of Sorel on the make is hollow, during use, can completely spread mortar, increases integrality of wall and shock resistance.Fire prevention, soundproof effect is good.Its production cost is lower than the price of other brick.
The specific embodiment
The present invention will be further described below in conjunction with the specific embodiment.
The present invention is made up of building-block and the core body that is positioned at the building-block cavity, and the raw material of production building block core body adopts the flyash of Tangshan power plant and the Sorel cement that sell in market.Weigh flyash and Sorel cement by weight, their weight percent content is respectively flyash 40%～60%, Sorel cement 30%～40%, respectively raw material being put into shearing stirrer for mixing by weight proportion stirs, add additive while stirring in shearing mixer, additive is selected acid, alkali or flyash excitant for use.Flyash excitant is selected any of sulfate or phosphate or iron chloride for use.Main effect is that raw material is fully merged, and becomes congee shape material under constantly stirring.The percentage by weight of flyash excitant addition is 10%～20%.
Concrete operations embodiment
1, get flyash 50kg, Sorel cement 40kg puts into shearing mixer with raw material, adds phosphate 10kg and stirs into congee shape material.Add 6% hydrogen peroxide or sodium carbonate (blowing agent) then in the congee shape material by weight percentage and stir foaming once more.
2, get flyash 40kg, Sorel cement 40kg puts into shearing mixer with raw material, adds iron chloride 20kg and stirs into congee shape material.Add 6% hydrogen peroxide or sodium carbonate (blowing agent) then in the congee shape material by weight percentage and stir foaming once more.
3, get flyash 60kg, Sorel cement 30kg puts into shearing mixer with raw material, adds sulfate 10kg and stirs into congee shape material.Then toward the congee shape
Add 6% hydrogen peroxide or sodium carbonate (blowing agent) in the material by weight percentage and stir foaming once more.
4, congee shape material is poured in the cavity of building-block, bonding being integral of congee shape material natural foaming in cavity made composite block;
5, composite block is placed on natural curing under 5 ℃～25 ℃ the environment, the moulding of building block nature was come into operation after 28 days after 24 hours.
Produce composite block with this method and can handle flyash in a large number, turn waste into wealth, the protection environment improves the economic and social benefits, and is a kind of building block production method that is worthy to be popularized.
