Abstract
The invention discloses special-purpose aqueous releasing agent of a kind of environment-friendly type concrete and preparation method thereof, first by lipid acid and C
3-C
5alkyl alcohol carries out reaction obtain fatty acid alkyl ester, subsequently fatty acid alkyl ester is mixed with modified polyether, emulsifying agent, separant and react, carry out emulsify at a high speed again and add permeate agent, rust inhibitor and stablizer, after mixing, namely obtaining the special-purpose aqueous releasing agent of environment-friendly type concrete.Present method technique is simple, the obtained special-purpose aqueous releasing agent of environment-friendly type concrete has good demolding performace, the smooth zero defect of concrete surface after the demoulding, and mould concrete adhesive capacity is few, and to template non-corroding, there is environmental protection, economic harmless advantage.
Description
Technical field
The invention belongs to the technical field of material of construction, particularly relate to special-purpose aqueous releasing agent of a kind of environment-friendly type concrete and preparation method thereof.
Background technology
Concrete parting agent, also referred to as concrete isolation agent or demoulding lubricant, a kind of material or material of applying or being sprayed at template internal surface, it can produce one deck barrier film, play lubrication and buffer action, bonding strength between effective minimizing concrete and template, impels concrete can depart from template smoothly when form removal, keeps concrete shape complete bright and clean.As the supplementary material of concrete construction, concrete parting agent and concrete almost have identical history, as far back as the twenties in last century, various countries utilize aqueous soup solution, waste diesel, used oil, lime, talcum powder etc. to make releasing agent in concrete works, but its stripping result is general, and aqueous soup solution is basic solution, affect concrete build shaping after surface quality.Along with the application of concrete placement novel process, the appearance of the new type formworks such as Sheet Steel Form, glass steel formwork, wooden form, glued mould, steel concrete shuttering and plastic inside lining follow board, and the raising of concrete surface quality and decoration grade, renewal, higher requirement are proposed to concrete parting agent.
From twentieth century beginning of the sixties, after external commodity releasing agent comes out, concrete formation releasing agent makes great progress in research, and releasing agent development is very swift and violent, so far defined a series of product, and progressively matched with modern construction, mould plate technique.The early stage concrete works major part of China is also use machine oil or used oil as release materials.Although this type of releasing agent demoulding is better, but the time of drying after coating is longer, very easily stain the clothing of constructing operation personnel and pollute reinforcing bar, and after concrete hardening form removal, also usually there is oil mark on the surface of structures, have impact on the attractive in appearance of concrete surface, and decorates the later stage of concrete surface, for example swabbing, paint, the bonding of the ornament layer such as to plaster brings very adverse influence, not too welcome by engineering circles.
Make a general survey of concrete parting agent product in domestic and international market, the starting material of most product all derive from machine oil, diesel oil, lubricating oil, paraffin, the materials such as paint, and these materials almost all belong to petroleum industry product, be all produce refinement in the oil being subordinated to Nonrenewable resources.And the development of human society causes the market requirement of concrete parting agent increasing, thus, the development research of environmental type releasing agent just seems even more important and urgent.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art part, provide special-purpose aqueous releasing agent of a kind of environment-friendly type concrete and preparation method thereof, there is good stripping result, the smooth zero defect of concrete surface after the demoulding, mould concrete adhesive capacity is few, to template non-corroding, and green, environmental protection, economy, to human body fanout free region.
One of the technical solution adopted for the present invention to solve the technical problems is:
A preparation method for the special-purpose aqueous releasing agent of environment-friendly type concrete, comprising:
1) according to the mass fraction, by the lipid acid of 50 ~ 100 parts, the C of 10 ~ 50 parts
3-C
5alkyl alcohol, the stopper accounting for lipid acid and alkyl alcohol total mass 1 ~ 3%, the catalyzer accounting for lipid acid and alkyl alcohol total mass 2 ~ 4% join in reactor, temperature of reaction is 75 ~ 95 DEG C, and the reaction times is 2 ~ 4h, and reaction terminates rear cooling, generate fatty acid alkyl ester, be filmogen;
2) according to the mass fraction, the above-mentioned filmogen of 80 ~ 99 parts and the modified polyether of 1 ~ 20 part are added in reactor, at 30 ~ 50 DEG C, add the emulsifying agent of 0.5 ~ 4 part and the separant of 1 ~ 4 part, stir 20 ~ 40min; Add the emulsified water of 1 ~ 10 part, then stir 20 ~ 40min, namely obtain pre-emulsion;
3) above-mentioned pre-emulsion is carried out emulsify at a high speed in the high-speed emulsifying machine of 1000 ~ 2000r/min, again according to the mass fraction, add the permeate agent of 0.05 ~ 1 part, the rust inhibitor of 0.1 ~ 1 part, the stablizer of 0.1 ~ 5 part, continue stirring 10 ~ 30min, namely obtain the special-purpose aqueous releasing agent of environment-friendly type concrete.
