Description
Technical field
The present invention relates to cast-in-place concrete construction technical field, more particularly to a kind of concrete component method for demoulding.
Background technology
With the continuous improvement of building trade technical merit, concrete construction will not only ensure performance indications, to its outward appearance
Quality it is also proposed requirement higher.Still generally coagulation is poured in current cast-in-place concrete construction by the way of template formwork
Soil, in order that pour rear pattern plate will not be bonded on concrete surface, causes form removal difficult or influences the surface light of concrete component
Cleanliness, frequently with template inner surface smearing release agent.
Releasing agent is broadly divided into oiliness, aqueous and resinae releasing agent, in order to ensure stripping result, no matter which kind of releasing agent
All there is the characteristics of density is high, adhesive force is strong, although form removable is easy, but releasing agent is readily adhered to concrete surface,
Puzzlement is caused to follow-up plastered work, drum is easily played on surface after plastering.
There is a method in which, it is exactly, without releasing agent, and to fix one layer of lining cloth in template inner surface, it is also possible to play help
The effect of the demoulding, but lining cloth can also stick to concrete surface sometimes, and be not easily cleaned.
The content of the invention
The invention provides a kind of concrete component method for demoulding, one layer of interleaving agent is first applied using in template inner surface,
One layer of method for being impregnated with the lining cloth of liquid parting is fixed again, and not only the demoulding is easy, and can ensure that lining cloth does not adhere to coagulation
Native surface；Can also play a part of to protect template surface not to be scratched and prevent corrosion in addition.
In order to achieve the above object, the present invention is realized using following technical scheme：
A kind of precast concrete method for demoulding, sets barrier coat and is impregnated with the lining of liquid parting successively in template inner surface
Cloth, realizes precast concrete fast demoulding and improves the surface quality of precast concrete after the demoulding；Specifically include：
1) template inner surface sets barrier coat；Barrier coat spraying or brushing interleaving agent by way of set, it is described every
It is made up of by volume following components from agent：
Liquid rosin：Used oil：Bobbin oil=1~3；8~20：1.5~5；
Above component is well mixed to be made interleaving agent；
2) fixation of barrier coat outside is impregnated with the lining cloth of liquid parting in template, and liquid parting has following components by weight
Example composition：
15~25 parts of oils；
1~5 part of defoamer；
3~5 parts of activating agent；

0.3~0.7 part of preservative；
0.1~0.2 part of stabilizer；
40~50 parts of water；
Process for preparation is：Add water in a kettle., be stirred continuously lower addition preservative and activating agent, be warming up to 35~45
Degree, adds stabilizer, continues to stir and be warmed up to 70~80 degree, pours into emulsifying agent and assistant for emulsifying agent, treats the transparent shape of solution
During liquid, oils and defoamer are added, continue stirring to all components and be completely dissolved；
The liquid parting that will be prepared is poured into the liquid tank with lining cloth width fits, and liquid tank side is provided with rotating filter cartridge,
Lining cloth immersion liquid tank in after 1~3 minute, stretch it is open and flat open, individual layer lining cloth is by side between liquid tank and rotating filter cartridge
Gap in pass through, be uniformly attached on lining cloth in rotating filter cartridge squeezing action bottom knockout liquid；
The lining cloth that liquid parting will be impregnated with is tightened and is fixed in template；
3) when constructing, routinely construction method carries out formwork, concreting, stripping operation.
The oils is one or more any mixing in machine oil, mineral oil, animal fat, oil emulsion.
The defoamer is any one in silicone emulsion, high-carbon alcohols or polyethers defoamer.
The activating agent is organic active agent or inorganic active agent.
The emulsifying agent is AEO.
The assistant for emulsifying agent is stearic acid.
The preservative is borax.
The stabilizer is rare-earth stabilizer.
Compared with prior art, the beneficial effects of the invention are as follows：
1) use and first apply one layer of interleaving agent in template inner surface, then fix one layer of side for being impregnated with the lining cloth of liquid parting
Method, not only the demoulding is easy, and can ensure that lining cloth does not adhere to concrete surface, can not only improve concrete surface matter
Amount, and the operation that is conducive to subsequently plastering etc. is smoothed out；
2) separation layer and lining cloth can play a part of to protect template surface not to be scratched and prevent corrosion, be conducive to template
Scene turnover is recycled, and reduces template repair amount；
3) interleaving agent and liquid parting is raw materials used is readily obtained, free from environmental pollution, low cost, production method is simple.
