Description

One kind hating oily self-cleaning dust-proof coatings and its manufacturing method
Technical field
The present invention relates to composite coating technical fields more particularly to one kind to hate oily self-cleaning dust-proof coatings and its manufacturer Method.
Background technique
Coatings have the coating of good electrical insulation.There are good electrical property, hot property, mechanical performance and chemically Energy.Mostly varnish, also coloured enamel.Coatings in present routine techniques generally use inorganic-organic polymer base-material, also have It uses inorganic matter for base-material completely, is mainly characterized by all being made of volume resistivity height, hard-packed inorganic crystal material, Such as aluminium oxide, silicon nitride are filler, be high temperature film forming matter using ceramic particle based on, form high-temperature-resistant insulating paint, it is this kind of exhausted Edge coating can be brushed in various materials, normal temperature cure, and curing time was at 24 hours or more.
General photocureable coating is to be not required to heat using ultraviolet light as the paint solidification energy, can be in paper, plastics, leather With rapid film-forming on the inflammable ground such as timber.Photocureable coating in the prior art is mainly by photosensitive resin, photosensitizer (light Initiator) and diluent composition, while some additives, such as heat stabilizer are added, pigment and filler is added when preparing colored paint.Light Quick resin is usually the low-molecular-weight resin for having unsaturated bond, such as unsaturated polyester (UP), acrylic oligomers；Photosensitizer is easy The compound that ultraviolet light generates living radical is absorbed, such as benzophenone, styrax alkyl ether；The main function of diluent is Viscosity of the coating is reduced, while also participating in film-forming, as reactive diluent, such as styrene, acrylate.Photocureable coating Advantage is curing time short (part second to a few minutes), solidification temperature is low, volatile matter is low, to save the energy, resource-saving, without public affairs Harmful, efficient coating new varieties；The disadvantage is that free radical type photocureable coating solidification process is suppressed by oxygen, surface cure is not It is good.
But all coatings are without self-cleaning, oil-stain-preventing, dust-proof function in currently available technology, and all light are solid Change coating and be applied to the simple surfaces such as metope, woodenware merely, there is presently no the photocuring paintings for being applied to steel structure surface Expect (steel material water absorbent surface is poor, slow curing, this is the basic reason that it does not apply photocureable coating), while all at present The insulating properties of photocureable coating is poor.
In the case where reality, the dust carbon elements or other conductive elements of all chemical plant substation control buildings in China contain It measures higher, is easy one layer of dust of absorption on the surface of electrical structure, this dust easy conductive, the time is long easily to induce electrical breakdown, In addition the air structure in chemical plant itself, easily causes explosion, it is abnormally dangerous.And currently not yet for the research and development of this pain spot The prior art.
Therefore need in the market it is a kind of hate it is oily, self-cleaning, dust-proof, insulate hate oily self-cleaning dust-proof coatings.
Summary of the invention
To solve drawbacks described above existing in the prior art, the present invention is intended to provide hating oily, self-cleaning, dust-proof, hating of insulating Oily self-cleaning dust-proof coatings.

2. prefabricated the stage 1 is just put into poly solution what 1. step obtained) step 1. prepare the bis- hydroxymethyl propionic acids of remaining 2,2-, Whole isophorone diisocyanate, neopelex, polyethylene glycol 400, methacrylic acid -2- hydroxy methacrylate, six Methylene diisocyanate, hydroxypropyl acrylate monomer, triethylenediamine put into the stage 1 after mixing) 2. step prepares Protective atmosphere-compressive reaction kettle in, be passed through air pressure in argon gas to kettle and be pressurized to 2MPa-2.5MPa, be warming up to 100 DEG C -115 DEG C, 1h-1.5h is reacted, partial polymerization products are obtained；
3. the stage 1 is added in 2. partial polymerization products that step obtains) 1. step prepares N, and N- methylene-bisacrylamide rises It is depressed into 4MPa-5MPa, is warming up to 120 DEG C -130 DEG C, heat preservation 3h-3.5h progress secondary cross-linking, to product nature after the completion of crosslinking Be cooled to room temperature taking-up, obtain complicated organic solution, be uniformly blended into the stage 1 in complicated organic solution) step 1. prepare two Aryl salt I-250 is simultaneously stirred evenly, then by distillation removal or acetone is added to the dense of complicated organic solution obtained Degree is adjusted to the kinematic viscosity 20mm of mixed solution2/s-25mm2/ s, that is, base solvent needed for obtaining；
4) coating system and use eventually
1. by the stage 3) base solvent that 3. obtains of step is coated uniformly on steel structure surface to be processed, brush face at room temperature Drying the stage 2 after 2min-2min10s) sol solutions that 4. obtain of step are uniformly sprayed using the spray pressure of 0.6MPa-0.8MPa It is coated in the base solvent solidfied material surface dried to semi-cured state, when base solvent being kept to brush time and sol solutions spraying Between time difference be 2min-2min10s, spraying after the completion of use 600mj/cm2-800mj/cm2The ultraviolet light of intensity density 2h-2.5h, i.e. completion coating brush curing molding.
