Abstract
The invention discloses a preparation method of a low-density concrete thermal insulation composite material. The preparation method comprises the following steps: mixing modified carbon fiber, modified Enteromorpha fiber, ligneous calcium sulphonate and calcium stearate and then adding the mixture to water with ten times of weight, uniformly stirring and then adding cement and coal ash, stirring under the state of introducing carbon dioxide, adding porous aluminum alloy while stirring, and finally curing under room temperature. The preparation method is green and environment-friendly, namely the disadvantage that the foam concrete is relatively low in strength is improved, and the heat insulation performance is also improved.
Description
Technical field
The present invention relates to a kind of preparation method of light weight concrete heat-preserving complex material.
Background technology
At present, building thermal insulation material is polystyrene and urethane mainly, and they are excellent lagging materials, but shortcoming is inflammable, and produce toxic gas after burning, can make people's death by suffocation.And foamed concrete and every other building materials nearly all have good consistency, and intensity controllable, and the combination of inside and outside layer body of wall is very good, can not form metope hollowing and subside.And in order to improve the heat-insulating property of foamed concrete, density must be reduced, reduce the reduction that density will cause intensity, this is the difficult problem perplexing it and use as lagging material.
Summary of the invention
For solving above technical problem, the object of this invention is to provide a kind of preparation method of light weight concrete heat-preserving complex material.
For achieving the above object, the invention provides following technical scheme,
A kind of preparation method of light weight concrete heat-preserving complex material, first add in the water of 10 times of weight after the modified carbon fiber of weight ratio 2-5:3-7:10:8-10, modification enteromorpha fiber, wooden calcium and calcium stearate being mixed, cement and flyash is added after stirring, 10min is stirred under the state being filled with carbonic acid gas, add porous Al alloy while stirring, stirring velocity is 1000rpm, maintenance 18-24 hour under last room temperature.Wherein the weight ratio of water, cement, flyash, porous Al alloy is: 100:120-150:30-40:0.5-1.5.
The invention has the beneficial effects as follows: environmental protection of the present invention, namely improve the shortcoming that foamed concrete strength ratio is lower, turn improve thermal and insulating performance simultaneously.
