Abstract
A kind of is the demoulding and curing agent for concrete and the manufacture method thereof of solvent with water, be by aliphatic acid, swell soil, soda ash, ethanol, precipitated calcium carbonate and water are formed, and above-mentioned raw materials mixed at a certain temperature form, the demoulding and curing agent for concrete that adopts above-mentioned prescription and method to make, can not only overcome the deficiencies in the prior art effectively, be easy to the demoulding, environmentally safe, cheap, easy to use, and concrete had good maintenance action, and be suitable for the concrete construction building site of various environment and condition, particularly be suitable for high level, adopt underground and water-deficient area.
Description
The present invention relates to a kind of demoulding and curing agent for concrete and manufacture method thereof of the demoulding and concrete curing when in building operations, being used for concrete pouring.
Along with China's development of economic construction, capital works are increasing, and almost all adopt the concrete steel wooden form method of forming to construct in the present capital works, need to adopt concrete parting agent and curing agent for guaranteeing construction quality and reducing construction costs, the concrete parting agent that adopts in the engineering is generally oil refine thing and regeneration petroleum-type product at present, curing agent then all adopts water, it is undesirable that the former exists stripping result, influence workmanship, particularly environment there are deficiencies such as pollution, it is long that the latter then exists curing period, curing condition is subjected to limitation (as the high-altitude, underground and multiaspect is constructed, water-deficient area etc.) deficiency, thereby cause construction costs to increase or reduction engineering design label, even cause engineering to be scrapped or engineering accident owing to maintenance is bad.
Purpose of the present invention just is to provide a kind of can effectively overcome the prior art deficiency, both had good stripping result to guarantee the recycling of template, having again has fabulous maintenance action and cheap demoulding and curing agent for concrete and manufacture method thereof to the concrete pouring part.
The objective of the invention is to realize by the following method: demoulding and curing agent for concrete of the present invention is made up of aliphatic acid, swell soil, soda ash, ethanol, precipitated calcium carbonate and water, and its charge ratio is: (weight portion)
Aliphatic acid: 8～12 swell soils: 5.5～7 soda ash: 6～7
Ethanol (95%): 5～6 precipitated calcium carbonates: 4～5 water: 100
Wherein aliphatic acid specifically refers to octadecyl acid or cetyl acid, and the swell soil specification is more than or equal to 200 orders; Manufacture method is: will join by the aliphatic acid of above proportioning stir in the ethanol that is heated to more than 60 ℃ make it the dissolving, add the water more than 60 ℃, progressively add soda ash then and make it neutralization, the pH value that makes solution is 6～6.5, add swell soil, be heated to again more than 70 ℃ fully and stir, add stir back and make it cooling and get final product of precipitated calcium carbonate at last.
The demoulding and curing agent for concrete that adopts above-mentioned prescription and method to make; the concrete pouring part had the good demoulding and maintenance action; its demoulding mechanism and maintenance mechanism are: during use; with above-mentioned demoulding and curing agent brushing on template; when fluid concrete; form the close film of Yi Ceng Cause between concrete and the template; because the difference of planeness between template and the concrete surface; the layer protective layer that adhesion of film forms at concrete surface during the demoulding; with isolated concrete and air; thereby stopped the volatilization of moisture content in the concrete effectively; if after the demoulding again at concrete surface brushing one deck demoulding and curing agent for concrete of the present invention; then its surperficial percentage of water loss is not more than 4%, surpasses U.S. BRS-41Q standard, reaches the purpose of concrete curing.
The demoulding and curing agent for concrete that adopts above-mentioned prescription and method to make, can not only overcome the deficiencies in the prior art effectively, be easy to the demoulding, environmentally safe, cheap, easy to use, and concrete had good maintenance action, the concrete construction building site that is suitable for various environment and condition particularly is suitable for high level, underground and water-deficient area employing.
Embodiment: at first by following proportion ingredient:
Octadecyl acid: 8 swell soils (〉=200 order): 6 soda ash: 6
Ethanol (95%): 5 precipitated calcium carbonates: 3.5 water: 100
With ethanol with being steam heated to 60 ℃, again octadecyl acid is mixed with it and make it and dissolve, the water that adds 70 ℃, progressively add soda ash then and make it neutralization, the pH value that makes solution is 6～6.5, adds swell soil, is heated to 90 ℃ again, fully stirred 40 minutes, add stir back and make it cooling and be finished product of precipitated calcium carbonate at last.
