Abstract
Template surface coating and compound method thereof when the present invention relates to a kind of construction work placing concrete, releasing agent is made up of oil, tween, sapn, polyvinyl alcohol, water, lipid acid, petroleum product, phosphoric acid, Ke Xingjia etc.This releasing agent stripping result is good, and film formation time is fast, does not pollute reinforcing bar and concrete surface, the ideal mode plate coating when being the building placing concrete.
Description
Template surface coating when the present invention relates to a kind of construction work placing concrete.
At present, existing building mostly is oils, emulsification oils, paraffin wax class, fatty acid etc. with releasing agent both at home and abroad.This class releasing agent is difficult for dry, pollutes reinforcing bar and concrete surface easily, and folding mould rear surface oil removal workload is big, and the releasing agent raw material that has lacks or the cost height, is difficult for promoting the use of.
Purpose of the present invention is exactly at the deficiencies in the prior art, and provides a kind of tackiness good, strong adhesion, and the film forming rear stability is good, the new type release agent of the easy demoulding under graviational interaction.
The present invention is achieved in that this releasing agent proportioning raw materials emulsifying part is (forming in weight percent): used oil (gear oil) 27-35%, water 55-56%, polyvinyl alcohol 14-3%, tween 2-4%, sapn 1-2%, acidifying part proportioning is (forming in weight percent): oil in water emulsion 50-42%, water 40-40.5%, lipid acid 7.5-14.5%, petroleum product 2-2.5%, phosphoric acid 0.01-0.17%, Ke Xingjia 0.49-0.33%.
In waste oil, under condition of stirring, add emulsifier tween, sapn, in above-mentioned solution, add water, under stirring state, add polyvinyl alcohol then, it is an amount of to get above emulsified machine oil again, adds stearic acid under stirring state, is warmed up to 60-80 ℃, add hot water, do not stop to stir, stable until Liquid Paraffin, drip phosphoric acid, stir, add a small amount of koH and stir and get final product.
Describe present embodiment in detail below in conjunction with embodiment 1:
1, in 85 parts of waste oil, under stirring state, add tween, sapn, in 15 minutes, drip, stirred then 0.5-1 hour, the water that in above-mentioned solution, adds 212.5 parts, stirred 0.5-1 hour, add 105 parts of poly-second combustion alcohol (10%) then, stirred 0.5-1 hour, 55 parts of above emulsified solns are heated to 50-60 ℃, add down 2.5 parts of stearic acid stirring to tremble, be warmed up to 60-80 ℃, add 45 parts of hot water, ceaselessly stirred 30 minutes, stable to white missible oil, in missible oil, drip 0.01 part of phosphoric acid (85%) again, add 0.02 part of KOH after continuing then to stir, be releasing agent after stirring.
Embodiment 2,3,4 steps are with embodiment 1.
When practicality, water: releasing agent=1: 4.Smear punching block 3-4 time, (20-30 minute) gets final product behind the airing.
One, emulsifying part, its composition of raw materials such as following table:
Item number 234
Raw material
Used oil+useless gear oil 27 20 35
Water 55 51 56
Polyvinyl alcohol (10%) 14 25 3
Tween-60 234
Arlacel-60 212
Two, acidifying part, its composition of raw materials such as following table:
Item number 234
Raw material
Oil in water emulsion 50 55 42
Water 40 42 40.5
Lipid acid 7.5 2.5 14.5
Petroleum product 2 2.5
Phosphoric acid (85%) 0.01 0.25 0.17
Ke Xingjia 0.49 0.25 0.33
Claims (3)
1, a kind of releasing agent when being used for the construction work placing concrete, it is characterized in that releasing agent needs to make through emulsification, acidifying two portions, wherein the emulsifying part proportioning raw materials is (forming in weight percent): used oil (gear oil) 27-35%, water 55-56%, polyvinyl alcohol 14-3%, tween 2-4%, sapn 1-2%, acidifying part proportioning is (forming in weight percent): oil in water emulsion 50-42%, water 40-40.5%, lipid acid 7.5-14.5%, petroleum product 2-2.5%, phosphoric acid 0.01-0.17%, Ke Xingjia 0.49-0.33%.
2, releasing agent according to claim 1, the best proportioning that it is characterized in that this releasing agent is: the emulsifying part proportioning is: used oil 20%, water 51%, polyvinyl alcohol (10%) 25%, tween 3%, sapn 1%, acidifying part proportioning is: oil in water emulsion 55%, water 42%, lipid acid 2.5%, phosphoric acid (85%) 0.25%, Ke Xingjia 0.25%.
3, a kind of releasing agent when being used for the construction work placing concrete, its technology is:
A, add waste oil stirring to tremble in the situation downhill reaction still, add the tween sapn thereafter,
B, in the solution of a top, add water, and under stirring state, add polyvinyl alcohol,
C, to get b item solution an amount of, adds stearic acid under stirring state, is warmed up to 60-80 ℃, adds hot water again in this solution, do not stop to stir, stable until Liquid Paraffin,
D, in solution, drip phosphoric acid, stir to c,
E, in d item solution, add a small amount of koH and stir and get final product.
