Description of drawings
Fig. 1 is the coating preparation process flow sheet that the embodiment of the invention provides.
Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
Fig. 1 shows the coating preparation technical process that the embodiment of the invention provides.Mainly may further comprise the steps:
(1) modification of silicon-dioxide
This experiment combines physical dispersion and chemical dispersion, at first nano-silicon dioxide particle is carried out ball milling, then adopt vinyl three ('beta '-methoxy oxyethyl group) silane to mix with silicon dioxide granule silicon dioxide granule is carried out modification, obtain the silicon dioxide granule after the modification.
(2) configuration mother liquor and solvent
Be mixed with solvent with analytical pure propyl carbinol and analytical pure dimethylbenzene with 7: 3 ratio, in the wide-necked bottle of packing into.The Resins, epoxy (6101) that takes by weighing certain mass is M1, and the solvent and the Resins, epoxy mixing that take by weighing the 2/3M1 quality are made into mother liquor again, carry out for subsequent use in the wide-necked bottle of packing into.
(3) preparation finished mother liquid
To add behind the different content ball milling in the mother liquor that prepare and silicon dioxide granule after modification, for reaching effective dispersion of silicon-dioxide, it be under 230 rev/mins of conditions mother liquor to be carried out ball milling at rotating speed that this paper adopts ball mill, forms finished mother liquid after half hour.
(4) configuration solidifying agent
Be mixed with solvent with analytical pure propyl carbinol and analytical pure dimethylbenzene with 7: 3 ratio, in the wide-necked bottle of packing into.Take by weighing the polyamide resin that quality is M1, put into beaker.Getting quality in 1: 1 ratio is the propyl carbinol of M1 and the mixing solutions of dimethylbenzene, pours in the beaker, stirs with stirring rod, is prepared into solidifying agent.
(5) preparation coating
Finished mother liquid and the solidifying agent that configures take the ratio preparation coating of mass ratio as 2: 1, are coated with after the sample coating for preparing left standstill a slaking in hour, coated sample is for subsequent use after 50 ℃ of lower insulation oven dry.
Combine with chemical dispersion by physical dispersion, can better change the size of particles of silicon-dioxide, thereby it is more even that silicon dioxide granule after the modification is disperseed in mother liquor, reach the purpose of modification.The content of coupling agent is in 3.5%-5% in the mother liquor, the dispersion effect of its silicon-dioxide in mother liquor is best, the spread coefficient of water in free film is minimum, illustrate that prepared coating shield performance is best, barrier propterty is best, when the content of silicon-dioxide in mother liquor in the 3%-6% interval, its porosity less.
