The last PH=8-9 of emulsion is as the criterion
Water is pressed the needs of product export concentration and is decided
The preparation technology of concrete parting agent is: with industrial waste mixing higher alcohols, vegetable oil residue and appropriate alkaline liquor (caustic-soda aqueous solution) as 50%, mix (because the waste material composition is not really uniform and stable by proportioning, kind is not exclusively the same in addition, so adding alkali number should increase and decrease as one sees fit, its addition is to have reacted the emulsion of the final gained in back, the PH=8-9 that is concrete parting agent is as the criterion) this mixture is added thermal response, during to 100 ℃, the volatilization of a large amount of steam and a small amount of low-molecular-weight organic matter is promptly arranged, continue heating 2-3 hour, when steam has been arranged substantially, react and finish, add water (amount of water is as the criterion with required emulsion ultimate density) in 85-95 ℃, stir, add used oil more in proportion and stir, obtain colloidal emulsion or the oily liquids (color and luster is different with the difference of waste material) of PH=8-9, be concrete parting agent of the present invention.General emulsion concentration is 10-30% (weight).
In the industrial waste of the present invention, mixing the higher alcohols waste material can be the various waste materials that contain higher alcohols, as producing the leftover bits and pieces of lauryl alcohol with natural coconut oil, the mixing higher alcohols leftover bits and pieces that is produced during petrochemical industry is synthetic etc.; Any plant oil leftover that vegetable oil residue produces when being meant various vegetable oil mill polished fat, as linseed oil, castor oil, tung oil, Chinese catalpa oil, rapeseed oil, soybean oil, peanut oil, cottonseed oil, palm oil, corn oil, sunflower oil, oil extracted from rice husks etc.; Used oil can be lightweight and the heavy machinery oil that various machineries were used, as 10#, and 20#, 30#, 40# machinery oil, weaving machine oil, refrigerator oil, turbine oil, transformer wet goods; Alkali can be various technical grade alkali, as NaOH, and the potassium hydroxide or their aqueous solution, ammoniacal liquor, monoethanolamine, diethanol amine, triethanolamine etc.
Concrete parting agent stripping result of the present invention is good, and we have carried out performance relatively to releasing agent of the present invention and soap releasing agent and oil emulsion releasing agent.Because country does not have unified test standard and method at present, can only directly observe the isolation effect (reducing friction the smooth situation of member face, the sticking grey situation of template etc. as reducing viscous force) of their low concentrations.All adopt the releasing agent of 3% (weight) concentration, brushing cement briquette model is a plurality of respectively under identical condition for this reason, the concrete that reinjects, and sclerosis back form removal, its isolation effect is:
Oil emulsion releasing agent＞releasing agent of the present invention (not containing used oil)＞soap releasing agent
If add the 10# used oil of 5% (weight) in the releasing agent of the present invention, other conditions are constant, and its isolation effect is:
Oil emulsion releasing agent=releasing agent of the present invention (containing used oil)＞soap releasing agent
