Problems solved by technology

The existing release agent generally uses engine oil, which is cheap, but the oil applied on the ordinary steel formwork can only be used once, which increases the cost, and also makes the surface of the traditional wooden formwork rough and easy to "run the mold".

Embodiment 1

[0010] Embodiment 1: A kind of release coating for steel formwork, mainly made of the following raw materials in parts by weight: 100 parts of polyethylene resin, 5 parts of polyethylene wax, 10 parts of zinc oxide, 3 parts of talcum powder; above-mentioned each raw material is Commercially available industrial grade products. The above-mentioned polyethylene wax has a melting point of 109-111° C. and a particle size of 6.0-6.5 microns.

[0011] The preparation method of the above coating: Add polyethylene wax, zinc oxide and talcum powder into the polyethylene resin under stirring state and stir for 8 hours to obtain a mixture, grind the mixture to a fineness of 45-50 microns, and obtain the described Steel formwork release coating.

[0012] The fineness is measured according to GB1724-79 paint fineness determination method.

[0013] When in use, the paint of the present invention is coated on the steel formwork, and the surfaces of the steel formwork and the concrete are f...

Embodiment 2

[0014] Embodiment 2: basically the same as Embodiment 1, the difference is the coating formula: 90 parts of polyethylene resin, 3 parts of polyethylene wax, 8 parts of zinc oxide, 2 parts of talcum powder.

[0015] The preparation method of the above coating: Add polyethylene wax, zinc oxide, and talcum powder into polyethylene resin under stirring state and stir for 6 hours to obtain a mixture, grind the mixture to a fineness of 45-50 microns, and obtain the described Steel formwork release coating.

Embodiment 3

[0016] Embodiment 3: basically the same as Embodiment 1, the difference is the coating formula: 110 parts of polyethylene resin, 8 parts of polyethylene wax, 12 parts of zinc oxide, 5 parts of talcum powder.

[0017] The preparation method of the above coating: Add polyethylene wax, zinc oxide and talcum powder into the polyethylene resin under stirring state and stir for 7 hours to obtain a mixture, grind the mixture to a fineness of 45-50 microns, and obtain the described Steel formwork release coating.

Abstract

The present invention discloses a steel template demolding coating, which is prepared ??mainly by the following raw materials, by weight, 90-110 parts of a polyethylene resin, 3-8 parts of polyethylene wax, 8-12 parts of zinc oxide, and 2-5 parts of talc powder. The steel template demolding coating of the present invention has the following advantage that: after a common steel template is coated with the coating containing a hydrophobic active agent in the present invention, the steel template and the concrete surface are smooth, and are not easily corroded, such that multiple uses can be achieved.

Description

technical field [0001] The invention relates to a paint, in particular to a steel formwork release paint. Background technique [0002] The concrete pouring of high-end buildings has extremely high requirements on the surface, and a release agent is usually used for demoulding. The function of the release agent is to reduce the bonding force between the formwork and the concrete and facilitate demoulding. Existing mold release agents generally use engine oil, which is cheap, but the oil coated on the ordinary steel formwork can only be used once, which increases the cost, and also makes the surface of the traditional wooden formwork rough and easy to "run the mold". Contents of the invention [0003] Purpose of the invention: The purpose of the present invention is to overcome the deficiencies of the prior art and provide a steel formwork release coating capable of improving the smoothness of the steel formwork and concrete surfaces and its preparation method. [0004...
