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
The present invention relates to a kind of coating, is a kind of Sheet Steel Form release coating specifically.
Background technology
The concrete cast of high-end building is high to surface requirements, can adopt releasing agent to carry out the demoulding usually, and the effect of releasing agent is to reduce template and concrete cohesive force, is convenient to the demoulding.Existing releasing agent generally adopts machine oil, and the price of machine oil is low, but the machine oil that is coated with on the ordinary steel template die can only use once, thereby has increased cost, but also timber shuttering surface irregularity that can be traditional and easy " race mould ".
Summary of the invention
Goal of the invention: the objective of the invention is in order to overcome the deficiency of prior art, a kind of Sheet Steel Form release coating that can improve Sheet Steel Form and concrete surfacing slickness and preparation method thereof is provided.
Technical scheme: in order to solve the problems of the technologies described above; The technical scheme that the present invention adopted is: a kind of Sheet Steel Form release coating, mainly process: polyvinyl resin 90-110 part, polyethylene wax 3-8 part, zinc oxide 8-12 part, talcum powder 2-5 part by the raw material of following parts by weight.
As further improvement of the present invention, mainly process: 100 parts of polyvinyl resins, 5 parts of polyethylene waxs, 10 parts in zinc oxide, 3 parts of talcum powder by the raw material of following parts by weight.
Further, said polyvinyl resin, polyethylene wax, zinc oxide, talcum powder are technical grade.
The preparation method of above-mentioned Sheet Steel Form release coating; Under whipped state, stirring in polyethylene wax, zinc oxide, the talcum powder adding polyvinyl resin was obtained compound after 6-8 hour; Compound is ground to fineness 45-50 micron, promptly obtains said Sheet Steel Form release coating.
Beneficial effect: compared with prior art, advantage of the present invention is: on the ordinary steel template die, apply the coating of the present invention that contains not hydrophilic active agent, make Sheet Steel Form and concrete surfacing smooth, easy-to-rust does not use thereby reach repeatedly.
Embodiment
Further illustrate the present invention below in conjunction with specific embodiment; Should understand these embodiment only be used to the present invention is described and be not used in the restriction scope of the present invention; After having read the present invention, those skilled in the art all fall within the application's accompanying claims institute restricted portion to the modification of the various equivalent form of values of the present invention.
Embodiment 1: a kind of Sheet Steel Form release coating, mainly process: 100 parts of polyvinyl resins, 5 parts of polyethylene waxs, 10 parts in zinc oxide, 3 parts of talcum powder by the raw material of following parts by weight; Above-mentioned each raw material is commercially available technical grade product.The fusing point of above-mentioned polyethylene wax is that 109 ~ 111 ℃, particle diameter are 6.0 ~ 6.5 microns.
The preparation method of above-mentioned coating: under whipped state, stirring in polyethylene wax, zinc oxide, the talcum powder adding polyvinyl resin was obtained compound after 8 hours, compound is ground to fineness 45-50 micron, promptly obtain said Sheet Steel Form release coating.
Fineness is measured according to GB1724-79 coating fineness assay method.
During use, coating of the present invention is coated on the Sheet Steel Form, Sheet Steel Form and concrete surfacing are smooth, and easy-to-rust does not use thereby reach repeatedly.
Embodiment 2: basic identical with embodiment 1, different is formulation for coating material: 90 parts of polyvinyl resins, 3 parts of polyethylene waxs, 8 parts in zinc oxide, 2 parts of talcum powder.
The preparation method of above-mentioned coating: under whipped state, stirring in polyethylene wax, zinc oxide, the talcum powder adding polyvinyl resin was obtained compound after 6 hours, compound is ground to fineness 45-50 micron, promptly obtain said Sheet Steel Form release coating.
Embodiment 3: basic identical with embodiment 1, different is formulation for coating material: 110 parts of polyvinyl resins, 8 parts of polyethylene waxs, 12 parts in zinc oxide, 5 parts of talcum powder.
The preparation method of above-mentioned coating: under whipped state, stirring in polyethylene wax, zinc oxide, the talcum powder adding polyvinyl resin was obtained compound after 7 hours, compound is ground to fineness 45-50 micron, promptly obtain said Sheet Steel Form release coating.
Embodiment 4: basic identical with embodiment 1, different is formulation for coating material: 95 parts of polyvinyl resins, 7 parts of polyethylene waxs, 9 parts in zinc oxide, 4 parts of talcum powder.
