Problems solved by technology

Most of the early concrete projects in my country also used engine oil or waste engine oil as a release agent, but the drying time after coating was long, and it was easy to contaminate the clothes of the construction operators and pollute the steel bars. After the concrete hardened and the formwork was removed, the surface of the structure Oil spots are also common

Embodiment 1

[0039] The present embodiment provides a kind of concrete release agent, and the raw material component of described concrete release agent comprises (calculated by mass parts, by every part=10g batching):

[0040]

[0041] Wherein, the composition of composite aqueous emulsifier is: the mass parts of TW-80, OP-10 and SDBS are respectively 4.4 parts, 4.2 parts and 2 parts. That is, the parts by mass of each emulsifier are: S-60:TW-80:OP-10:SDBS=10:4.4:4.2:2.

[0042] Its preparation method is as follows:

[0043] (1) Mix the oily emulsifier S-60 with rapeseed oil and stir until they merge to obtain solution A; mix the composite water-based emulsifiers (TW-80, OP-10 and SDBS) with water and stir until they merge, Obtain solution B;

[0044] (2) Add solution B dropwise to solution A, stir while adding dropwise, add preservative (triethanolamine) and stabilizer (xanthan gum) after dropwise addition, and configure it as a concrete release agent. Wherein, the temperature of t...

Embodiment 2

[0047] This embodiment provides a concrete release agent, the raw material formula and preparation method of the concrete release agent are basically the same as in Example 1, the only difference is that the composition of the composite water-based emulsifier is: TW-80, OP-10 and The mass parts of SDBS are 4 parts, 4 parts and 2 parts respectively, that is, the mass parts of each emulsifier is: S-60: TW-80: OP-10: SDBS=10:4:4:2.

[0048] After calculation and testing, the HLB value of the obtained concrete release agent is 9.3, and the stable days of the obtained concrete release agent are 75 days; the adhesion amount is 4.9g / m2 .

Embodiment 3

[0050] This embodiment provides a concrete release agent, the raw material formula and preparation method of the concrete release agent are basically the same as in Example 1, the only difference is that the composition of the composite water-based emulsifier is: TW-80, OP-10 and The parts by mass of SDBS are 4.8 parts, 4.4 parts and 2 parts respectively, that is, the parts by mass of each emulsifier are: S-60: TW-80: OP-10: SDBS=10:4.8:4.4:2.

[0051] Through calculation and test, the HLB value of the obtained concrete release agent is 9.6, and the stable days of the obtained concrete release agent is 60d; the adhesion amount is 6.0g / m 2 .

Abstract

The invention discloses a concrete release agent and a preparation method thereof. The concrete release agent comprises the following raw material components in parts by mass: 45-60 parts of vegetable oil, 7-13 parts of an oily emulsifier, 7-13 parts of a composite water-based emulsifier, and 180-300 parts of water, wherein the composite water-based emulsifier is selected from more than two of Tween, polyoxyethylene octyl phenol ether and sodium dodecyl benzene sulfonate. According to the concrete release agent, the oily emulsifier is matched with the water-based emulsifier, so that the concrete release agent is relatively good in stability and small in adhesion amount, meanwhile, the drying and film-forming time of the concrete release agent is relatively short, and a concrete surface decoration procedure is not influenced.

Description

technical field [0001] The invention relates to a concrete release agent and a preparation method thereof, belonging to auxiliary agents for concrete engineering construction. Background technique [0002] Since the release agent came out in the early 1960s, the release agent has developed very rapidly, and a series of products have been formed so far, and are gradually matched with modern construction and formwork technology. Most of the early concrete projects in my country also used engine oil or waste engine oil as a release agent, but the drying time after coating was long, and it was easy to contaminate the clothes of the construction operators and pollute the steel bars. After the concrete hardened and the formwork was removed, the surface of the structure Grease spots are also common. [0003] At present, the water-based release agent products developed abroad mainly prepare paraffin, oil and other substances into oil-in-water or water-in-oil emulsions or creams thro...
