Abstract
The invention discloses an emulsified engine oil water-based concrete release agent and a preparation method and application thereof, wherein the concrete release agent comprises the following raw material components in parts by mass: 40-80 parts of engine oil; 10-20 parts of oleic acid; 3-7 parts of span; 3-7 parts of tween. According to the invention, oleic acid is used to be matched with the water-based and oil-based emulsifiers, so that the stability of the concrete release agent is obviously improved, a higher dilution ratio of the release agent to water is obtained, the use cost of the release agent is greatly reduced, the adhesion amount is smaller, and the production cost is saved for each factory.
Description
Technical Field
The invention relates to an emulsified engine oil water-based concrete release agent, and a preparation method and application thereof, and belongs to an auxiliary agent for concrete engineering construction.
Background
The release agent is a functional substance between the mold and the finished product. The release agent is chemically resistant and does not dissolve when in contact with the chemical components of different resins, particularly styrene and amines. The release agent also has heat resistance and stress resistance, and is not easy to decompose or wear; the release agent adheres to the mold without transferring to the part being processed, and does not interfere with painting or other secondary processing operations. The amount of release agent used is also greatly increased due to the rapid development of injection molding, extrusion, calendering, molding, lamination and other processes.
Since the early 60 s of the twentieth century, the release agent developed very rapidly, and a series of products were formed so far and gradually matched with modern construction and template technologies. Most of the early concrete projects in China also use engine oil or waste engine oil as a release agent, but the drying time after coating is long, so that clothes of construction operators and polluted reinforcing steel bars are easily polluted, and after concrete is hardened and demoulded, oil spots are often formed on the surface of a structure.
At present, commercial concrete release agents at home and abroad are various in types, the release effects of different types of release agents on concrete and templates are greatly different, most of the release agents are oils, the raw materials are few, the cost is high, oil stains are easily generated in the production process, and the natural environment is polluted; the aqueous release agent is simple to operate, free of oil pollution and small in damage to the environment, so that the development of the release agent is of great significance.
Disclosure of Invention
The invention aims to solve the technical problems that (1) compared with most of engine oil release agents, the solution stabilization period is shorter; (2) the concrete sample block has a corrosion effect on the steel die; (3) more concrete residues are left on the mould; (4) the cost is higher and the dilution ratio is less.
In order to solve one or more technical problems, the invention provides an emulsified engine oil water-based concrete release agent which comprises the following raw material components in parts by mass:
preferably, the raw material components of the concrete release agent further comprise one or more of a pH regulator, a defoaming agent, a stabilizer and a film forming agent.
Preferably, the film forming agent is 10-20 parts of rosin by mass; and/or the pH regulator is 2-4 parts of sodium hydroxide. Wherein the sodium hydroxide and 2-5 parts of water are prepared into a sodium hydroxide solution for use. It can be seen that the amount of water added to the mold release agent is small, but it can be used after diluting with water at the time of use.
Preferably, the defoaming agent is 0.005 to 0.1 part by mass; and/or 0.1-0.3 part of stabilizer.
Preferably, the tween is selected from tween-60 or tween-80; and/or the span selects span-60 or span-80.
Preferably, the engine oil is one or more of #15 engine oil, #22 engine oil, #32 engine oil, #46 engine oil and #68 engine oil.
Preferably, the oil may also be selected from used oil.
Preferably, the engine oil is 50 to 60 parts by mass.
The invention also provides a preparation method of the concrete release agent, namely, the concrete release agent is obtained by mixing various raw materials.
The invention also provides application of the concrete release agent in the field of concrete release.
Preferably, the concrete release agent and water are diluted according to the mass ratio of 1:4-10 and then used.
Preferably, the mass ratio of span-60 to tween-80 is 1: 1.
Preferably, the antifoaming agent is model ST-60 antifoaming agent of south China sea field chemical, Inc. of Foshan City.
Preferably, the stabilizer is one or more of sodium carboxymethylcellulose, xanthan gum, hydroxymethyl cellulose, acrylamide, sodium alginate and hydroxypropyl methyl cellulose.
Specifically, the preparation method of the emulsified engine oil water-based concrete release agent comprises the following steps:
(1) preheating an oil product, namely stirring part of engine oil in a four-neck flask at 250rpm for 20min, and controlling the temperature at 100 ℃;

From the above examples, it can be seen that when oleic acid is selected to be compounded with aqueous and oily emulsifiers, the emulsifying effect is improved to maximize the dilution ratio of the release agent to water, and the stability of the emulsion is also improved. This is because the oleic acid, when compounded with several surfactants, reduces the surface tension of the emulsion, thereby increasing the stability of the emulsion. The mixing of nonionic surfactant molecules and ionic surfactants can form mixed micelles, and the principle is that the nonionic molecules are inserted between the ionic molecules, so that the electrical repulsion between the hydrophilic head groups of the original ionic molecules is weakened, namely the charge density of micelles is reduced. Na has less charge than Mg, namely the repulsion between SDS and nonionic surfactant molecules is small, the nonionic molecules are more easily inserted into the micelles of SDS, namely micelles are more easily formed, CMC is reduced to be lower, the effect is more obvious, and then the dilution ratio of the release agent and water is better, and the solution is more stable.
