The enhancement concrete release agent has the advantages of good releasing effect, high strength , zero pollution and the like and is a promising concrete admixture.
Description
Technical field
The present invention relates to a kind of enhancement mode concrete parting agent, belong to technical field of concrete additives.
Background technology
Along with the fast development of concrete, concrete admixture role in concrete construction also becomes increasingly to weigh
Want.Its not only volume little, and concrete performance can be improved, meet and be actually needed, cement can also be saved simultaneously, reduce energy consumption and
Reduce the effects such as pollutant emission.Common additive has: early strength agent, water reducer, air entraining agent, retarder, releasing agent etc..Its
In, concrete parting agent, also known as concrete isolation agent or demoulding lubricant, it is that one coats or is sprayed on template inwall, can produce
Raw one layer of isolating membrane, plays lubrication and buffer action, can also effectively reduce adhesive force between concrete and template simultaneously, make concrete
Template can be departed from when form removal smoothly, keep the intact material of concrete shape.
At present, the concrete parting agent on market is of a great variety, and different types of releasing agent is between concrete and template
Stripping result be not quite similar.Common are: soaps releasing agent, used oil class, plant oil and paraffin release agent.Soaps takes off
Though mould agent has cheap advantage, but after the fermentation of such releasing agent, gives out unpleasant stink, pollute environment, and be difficult to
The demoulding, concrete surface is coarse；Though used oil class releasing agent has cheap advantage, but greasy dirt easily pollutes the clothing of workmen
After thing and the demoulding, concrete surface is coarse, has black greasy dirt, is difficult to the demoulding；Though it is excellent that plant oil releasing agent has that raw material is easy to get
Point, but such is to be entirely vegetable oil, directly affects the effect theed cement solidifies, easily causes concrete surface coarse；Wax oil
Though class releasing agent has the advantage of the easy demoulding, but such contains the volatile organics such as formaldehyde in emulsifier, emulsifying agent
Organic solvent, has injury, and cost is higher human body.
Chinese patent Authorization Notice No.: CN103409218B discloses entitled " a kind of concrete parting agent and preparation side thereof
Method " patent, the composition of raw materials of this releasing agent is: water is the 80-95% of gross mass；The mass ratio of Adeps Sus domestica and Colophonium is 5:1；Its
Remaining in terms of the 100% of Adeps Sus domestica and the total amount of Colophonium, sodium hydroxide 10-26%；Emulsifying agent 10-30%；Tributyl phosphate 0.1-
1%；Formaldehyde 0.2-1.5%；Empgen BB 0.3-2.2%；Appropriate organo montmorillonite.Although it can obtain certain
Stripping result, but it is substantially or soaps releasing agent, still suffers from deficiency, can't make us in terms of concrete strength simultaneously
Satisfied.Additionally, the use of formaldehyde, it is unfavorable for environmental protection.Therefore, it is necessary for continuing to explore with research concrete parting agent.

2) 4 parts of Rhizoma amorphophalli glucomannans and 0.4 part of sodium stearate are placed in 55 DEG C of waters bath with thermostatic control, simultaneously under magnetic agitation state
H is added with titration mode2SO4Regulation pH is value 2.5, reacts 1.5h；Obtain mixture B, standby；
3) by after mixture A, B mix homogeneously, the nano zine oxide adding 3%, it is ultrasonic on 35KHz ultrasonic machine for being placed in frequency
15min, i.e. can get modified konjac glucomannan.
Enhancement mode concrete parting agent the most according to claim 1, it is characterised in that: described montmorillonite powder is through following
Step pretreatment:
First acid alcohol (hydrochloric acid: the dehydrated alcohol=1:1) solution of montmorillonite powder and equivalent is mixed, add after 15～20min 0.1～
It is on 20～30KHz ultrasonic machines ultrasonic 15～20min that 0.3 part of oleic acid is placed in frequency, then drying is ground into 200～300 mesh
Smectite powder.
