Problems solved by technology

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 quality, and endangering the health of operators; while water-soluble release agents are easy to operate and free of oil mist, which is beneficial to The environmental pollution is small, so the development of such release agents is of great significance

Embodiment 1

[0028] In parts by weight, put 20 parts of trimethylolpropane trioleate and 5 parts of isopropyl oleate into the reactor, start the stirring device, then add 1 part of Span80 and 2 parts of nonylphenol polyoxyethylene Ether (NP-10), mixed and stirred for 30min. Then add 0.5 parts of polyvinyl alcohol, 1 part of triethanolamine, 0.5 parts of silicone defoamer, 68 parts of water, and stir for 60 minutes. Finally, slowly add 2 parts of polyacrylate thickener (HT-9) for 20 minutes, and stir for 40 minutes to become the concrete release agent.

Embodiment 2

[0030] In parts by weight, put 12 parts of trimethylolpropane trioleate and 5 parts of liquid paraffin into the reaction kettle, start the stirring device, then add 1 part of Span80, 1 part of fatty alcohol block polyether MOA-3 And 2 parts of alkylphenol polyoxyethylene ether SOPE-10, mixed and stirred for 30min. Then add 1 part of polyvinyl alcohol, 1.5 parts of sodium borate, 3 parts of modified polyether defoamer HY-2045, 70 parts of water, and stir for 60 minutes. Finally, slowly add 3.5 parts of polyacrylic acid thickener HY-303 for 20 minutes, and stir for 40 minutes to become the concrete release agent.

Embodiment 3

[0032] In parts by weight, put 10 parts of trimethylolpropane trioleate, 5 parts of isopropyl oleate and 5 parts of naphthenic oil into the reaction kettle, start the stirring device, and then add 3 parts of fatty alcohol block polymer Ether MOA-4 and 6 parts of nonylphenol polyoxyethylene ether NP-10 were mixed and stirred for 30 minutes. Then add 1.5 parts of polyvinyl alcohol, 1 part of xanthan gum, 1.5 parts of sodium borate, 1.5 parts of triethanolamine, 2 parts of modified polyether defoamer HY-2045, 58.5 parts of water, and stir for 60 minutes. Finally, slowly add 5 parts of polyacrylate thickener HT-9 for 20 minutes, and stir for 40 minutes to become the concrete release agent.

Abstract

The invention discloses a concrete demoulding agent and a preparation method thereof. The demoulding agent is composed of the following raw materials in percentage by weight: 4 to 30% of oil substance, 1 to 10% of oily emulsifier, 1 to 10% of aqueous emulsifier, 1 to 10% of thickening agent, 0.1 to 5% of stabilizing agent, 0.1 to 5% of antirust agent, 0.1 to 5% of antifoaming agent, and 30 to 90% of water. The concrete demoulding agent has the advantages that the demoulding agent can be rapidly dried after film forming, the surface of moulded members is smooth and does not contain bubbles, the amount of residual ash in the mould is little, and the demoulding quality is good.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a concrete release agent and a preparation method thereof. Background technique [0002] Concrete release agent is a functional substance between the mold and the concrete component, which can prevent the concrete component from bonding with the mold or other slab surfaces, and can facilitate demoulding, improve production efficiency, and prolong the life of the mold. At the same time, it is a kind of processing aid that makes the surface of the product smooth, the size is qualified, and the scrap rate is reduced. [0003] 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, poll...
