Description
Technical field
The present invention relates to a kind of concrete product separating releasing agents and preparation method thereof, belong to concrete additives field.
Background technique
Release agent can improve product appearance and performance as the important auxiliary agent of one of forming concrete products process,
Improve product quality.Common release agent kind has wax class, silicone oil, soaps, used oil etc., has their own characteristics each；And it is common
Concrete product interleaving agent is mainly used oil release agent, and there are serious environmental pollutions, and mold should not clean, product
Surface is easy to produce due to the micro- hole of bubble bring, so being badly in need of developing a kind of concrete product isolation for overcoming disadvantages described above de-
Mould agent.
So researching and developing a kind of nono calcium carbonate modified silicone oil emulsion concrete product separating releasing agent of high solids content, it is used for
In the process of concrete product, realizes that raw material is separated with the smooth of metal die, improve yield rate, could meet well
The market demand.
Summary of the invention
Pore defect is few, high-quality concrete product of any surface finish to obtain, while realizing raw material and metal die
It smoothly separates, improves yield rate, the present invention provides a kind of concrete product separating releasing agents, while providing its preparation side
Method.
Purpose to realize the present invention, the present invention are prepared by raw material of silicone oil, emulsifier, water soluble salt calcium chloride and sodium carbonate
Active nano-calcium carbonate Modified silicon oil emulsion is a kind of new concrete product separating releasing agent, is isolated in concrete product
There is preferable application effect in demoulding.
Concrete product separating releasing agent of the present invention is prepared by following specific method:
Parts by weight of raw materials proportion is as follows:
Silicone oil 30---40
Modifying agent 1-10
Calcium chloride 0.3-5
Sodium carbonate 0.3-5
Diluent 9-55.9
Emulsifier 4---20
Defoaming agent 0.5-1
The modifying agent in ethyl alcohol, polyvinyl alcohol, stearic acid and its sodium salt at least two；The calcium chloride be go from
Sub- water is formulated the calcium chloride water that concentration is 0.5--2.5mol/L；The sodium carbonate be natrium carbonicum calcinatum powder or
Concentration is the aqueous sodium carbonate of 0.5-2.5mol/L；The diluent is deionized water；The emulsifier be Tween-20,
At least one of Tween-60, Tween-80, Arlacel-20, Arlacel-80, Arlacel-60；The defoaming agent is silicon oil foam killer.
Be prepared especially by following method: (1) according to said ratio, by silicone oil, emulsifier, modifying agent, calcium chloride,
Silicone oil-calcium chloride solution is made in deionized water mixing；(2) under stiring by natrium carbonicum calcinatum powder or aqueous sodium carbonate
It is slowly added in the above-mentioned silicone oil-calcium chloride solution being configured to, the molar ratio of calcium ion and carbanion is 1:1, has been added
Finish, defoaming agent is added, is warming up to 45-75 DEG C and is stirred to react, obtain the nono calcium carbonate modified silicone oil emulsion of w/o type；(3) it adds
Deionized water, stirs evenly, cool down phase inversion, obtains O/W type silicone oil nanometer calcium carbonate lotion.
Diluent is made into the concrete product separating releasing agent that solid content is 30%-40%.
The principle of the present invention is as follows: first a kind of water soluble salt being mixed with emulsifier, silicone oil, modifying agent transparent molten
Liquid, then another water soluble salt is added in former solution the inorganic nano calcium carbonate silicone oil cream for preparing pattern and size tunable
Liquid, simultaneously as Nano particles of calcium carbonate surface have very high surface can, and containing calcium ion, hydroxyl etc., be easy to adsorb or
Chemical reaction occurs with the modifying agent that contains in system and generates ionic bond, so that it is hydrophilic so that its surface from hydrophily is become oleophylic
Property, the reunion of nanoparticle is avoided, while improving the compatibility of itself and organic substance again.
The invention has the advantages that 1, be prepared in situ using nanometer calcium carbonate and organic binder matter new concrete product be isolated it is de-
Mould agent is a kind of wide 40-100 nm, the solid content of being distributed of nanometer particle size for the nono calcium carbonate modified silicon of high solids content of 30-40%
Fat liquor, demoulding of the release agent suitable for the process of concrete product, raw material are isolated with mold, can be real well
Existing raw material is smoothly separated with metal die, and excellent effect is easy to use, pollution-free, safe and reliable.Both it had overcome using used oil
Product brought by release agent bring problem of environmental pollution and inorganic particle interleaving agent emits white phenomenon, and increases mold
Durability reduces brushing number, protects die surface, while drawing compared with the nanoparticle of wide size distribution (40-100nm)
Enter, can extend die life with micro- hole on repairing mould surface and damage, and reduce surface defects of products, improve at
Product rate, while can make mold and product surface that there is self-cleaning effect, and have both isolating film as demolding film double effects.2, of the invention
Agents useful for same be it is non-toxic or low-toxic, the new concrete product separating releasing agent finished product of preparation belongs to green product.Using one
The characteristics of according to silicone oil emulsification process, i.e., w/o type microemulsion, then phase inversion preparation first is made by emulsifier and silicone oil in footwork technique
Nanometer calcium carbonate is prepared in situ in w/o type microemulsion preparatory phase in O/W type microemulsion, and then O/W type nanometer is prepared in phase inversion
Calcium carbonate silicone oil emulsion, and then obtain the concrete product separating releasing agent that solid content is 30%-40%.

20,0.5 part of Arlacel-20, measures 8 parts of deionized waters, and band is added and is stirred at reflux in the reactor of device, 50 DEG C stir into it is transparent molten
Liquid.0.5 part of defoaming agent is added, system is warming up to 55-65 DEG C, is stirred at reflux reaction 24.0h, adds deionized water, stops adding
Heat slowly stirs evenly, and cool down phase inversion, obtains the silicone oil emulsion concrete separating releasing agent that solid content is about 30%.
Comparative example 3:
Weigh 35 parts of silicone oil that average viscosity is 500cp, 7 parts of Tween 80s of emulsifier, 7 parts of Arlacel-80s, 0.5 part of Tween-20,0.5
Part Arlacel-20, measures 15 parts of deionized waters, and band is added and is stirred at reflux in the reactor of device, 50 DEG C stir into clear solution.Again
0.8 part of defoaming agent is added, system is warming up to 65-75 DEG C, is stirred at reflux reaction 20.0h, adds deionized water, stop heating, delays
Slowly it stirs evenly, cool down phase inversion, obtains the silicone oil emulsion concrete separating releasing agent that solid content is about 35%.
Isolating film as demolding film test: by taking concrete formation metal die as an example, using effect is as in the attached table.
Subordinate list:
The description of product:
The unmodified silicone oil emulsion concrete of the nono calcium carbonate modified silicone oil emulsion concrete parting agent of the present invention and same formula
Release agent is compared, and is sprayed primary release times and is significantly improved, the mold clean period is obviously prolonged, and defect rate is remarkably decreased, together
When release agent resting period be obviously prolonged, be conducive to transport and store.There is micro- hole etc. to lack especially for soon superseded surface
Sunken metal die, since Modified silicon oil emulsion concrete parting agent nanometer calcium carbonate of the present invention has the average grain of 40-100nm
Diameter, the nanometer calcium carbonate of different-grain diameter can repair micro- hole defect on metal die surface in use, prepare surface
Bright and clean qualified concrete product extends die life.
