Problems solved by technology

However, since no penetrating agent is used, the release agent cannot penetrate into the pore structure inside the concrete, so the pore structure inside the concrete cannot be eliminated; and the defoaming component is not introduced, so the pores on the concrete surface cannot be eliminated, and the demoulding effect of the concrete is affected. limit

Embodiment 1

[0038] Add 3 parts of polyethylene glycol oleate (PEG400DO) and 3 parts of sodium stearate into the stirring container, then add 20 parts of water, and heat up to 50°C while stirring to form emulsified water for later use.

[0039] Mix 3 parts of dioctyl maleate sodium sulfonate, 10 parts of 24-degree palm oil and 4 parts of sorbitan fatty acid ester (S-80), heat up to 50°C, stir well and add 1 part of MARLOX BR3551, made into a microemulsion mixture;

[0040] Then slowly add 6 parts of emulsified water to the microemulsion mixture, heat up to 50°C while stirring, stir until the emulsion turns milky white, stop adding emulsified water, increase the speed to 1000r / min, stir for 30min, and then cool to 30 ℃, and then 1 part of sodium benzoate, 0.1 part of potassium sorbate and the remaining 20 parts of emulsified water, and continue to stir for 15 minutes to obtain the environmentally friendly concrete release agent.

Embodiment 2

[0042] Add 2 parts of polyethylene glycol oleate (PEG400MO) and 2 parts of sodium lauryl sulfate into the stirring container, then add 40 parts of water, and heat up to 60°C while stirring to form emulsified water for later use.

[0043] Mix 2 parts of dioctyl maleate sodium sulfonate, 30 parts of palm oil at 44 degrees and 10 parts of sorbitan fatty acid ester (S-85), heat up to 60°C, stir well and add 2 parts of MARLOX BR3551 to make a microemulsion mixture;

[0044] Slowly add 14 parts of emulsified water to the microemulsion mixture, heat up to 45°C while stirring, stir until the emulsion turns milky white, stop adding emulsified water, increase the speed to 1000r / min, stir for 30min, and then cool to 30°C Next, 0.1 part of sodium benzoate, 0.5 part of potassium sorbate and the remaining 30 parts of emulsified water were stirred for 20 minutes to obtain the environmentally friendly concrete release agent.

Embodiment 3

[0046] Add 10 parts of polyethylene glycol oleate (PEG600DO) and 10 parts of sodium dodecylbenzenesulfonate into the stirring container, then add 60 parts of water, and heat up to 60°C while stirring to form emulsified water for later use.

[0047] Mix 1 part of dioctyl maleate sodium sulfonate, 60 parts of 52-degree palm oil and 10 parts of sorbitan fatty acid ester (S-40), heat up to 55°C, stir well and add 3 parts of MARLOX BR3551 to make a microemulsion mixture;

[0048] Slowly add 25 parts of emulsified water to the microemulsion mixture, heat up to 55°C while stirring, stir until the emulsion turns milky white, stop adding emulsified water, increase the speed to 1000r / min, stir for 30min, and then cool to 30°C , and then 2 parts of sodium benzoate, 1 part of potassium sorbate and the remaining 55 parts of emulsified water were stirred for 25 minutes to obtain the environmentally friendly concrete release agent.

Abstract

The invention relates to the field of concrete release agents, and provides an environment-friendly concrete release agent and a preparation method thereof. The release agent comprises emulsified vegetable oil, the emulsified vegetable oil is prepared by emulsifying vegetable oil in the presence of an emulsifier, and the emulsifier comprises a water-soluble emulsifier and an oil-soluble emulsifier; the defoaming component is polyoxyethylene oleyl alcohol ether and is used for eliminating bubble marks generated by the penetrant; the penetrating agent is used for enabling the defoaming component to penetrate into a hole structure in the concrete. The concrete release agent prepared by the invention has the characteristics of good release effect, high apparent quality, high concrete compressive strength and good durability.

Description

technical field [0001] The invention relates to the field of concrete release agents, in particular to an environment-friendly concrete release agent and a preparation method thereof. Background technique [0002] At present, mold forming is required in the production process of precast concrete components and pipe piles, and in the process of demoulding, due to the adhesion of formwork, product defects will increase production costs, and some components have relatively high requirements for appearance. High, ordinary engine oil cannot meet the market demand, and some release agents with better release performance are needed. At present, there are many types of commercial concrete release agents at home and abroad, and different types of release agents have different release effects on the concrete and formwork. Most of the release agents are oils, which have few raw materials and high cost. Oil mist is easy to be generated during the production process, polluting the air q...
