Description
Technical field：
The present invention relates to technical field of coatings, and in particular to a kind of blue tangerine line waterproof powder applied on electric appliance applies
Material.
Background technology：
Powdery paints, be it is a kind of it is novel be free of 100% solid powdery coating of solvent, have it is solvent-free, pollution-free, can
Recycling, saves the energy and resource, reduces labor intensity the features such as high with coating machinery intensity at environmental protection.Without primary coat, disposably apply
Work can be obtained the film of adequate thickness, and coating densification, adhesive force, impact strength and toughness are good, corner coverage
Height has excellent resistance to corrosive chemicals energy and electrical insulation properties.
Household electrical appliance refer mainly to the various electric appliances used in family and similar site and electronic apparatus, also known as day electricity consumption
Device.Household electrical appliance make people be freed from heavy, trifling, time-consuming housework, are created for the mankind more comfortable excellent
Living and working environment that is beautiful, being more advantageous to physical and mental health, provides colourful entertainment condition, it has also become Modern Home
The necessity of front yard life.
The rapidoprint of household electrical appliance is usually metal material, poor to the resistance of water, and household electrical appliance are once
If touching water, its service life can be influenced, it is serious to be more likely to that safety accident is caused.In order to improve the dicoration of household electrical appliance
And enhance the performances such as its wear-resisting, corrosion-resistant, impact resistance, it is general by the way of adhering to coast of paint film on its surface.And how
Having both excellent water proofing property while so that formed paint film is had excellent dicoration, wearability, corrosion resistance, impact resistance is
At present the technical issues of urgent need to resolve.
Invention content：
Technical problem to be solved by the present invention lies in a kind of high-decoration is provided, high water proofing property is applied on electric appliance
Blue tangerine line waterproof powdery paints.
The technical problems to be solved by the invention are realized using technical solution below：
A kind of blue tangerine line waterproof powdery paints applied on electric appliance is made of following components by weight percent：
Terminal carboxyl polyester resin 32.75kg, epoxy resin 31.58kg, bloom barium 14.62kg, delustring calcium 12.87kg, increase
Hard agent 0.47kg, titanium dioxide 22.223kg, levelling agent 0.351kg, ultramarine 0.137kg, carbon black 0.002kg, waterproofing agent 3.17kg.
The preparation method of the waterproofing agent is as follows：
(1) nitric acid of 1 mass parts is added in the silica gel of 1 mass parts, is heated to reflux 5h, is washed to distillation after cooling
Neutrality, sealing are placed, then with 6N hydrochloric acid in soaking at room temperature for 24 hours, then with distilling be washed to neutrality, then by processed silica gel as
120 DEG C of dry 10h, obtain activated silica gel in muffle furnace；
(2) polyacrylic acid, hydroxymethyl cellulose, chitosan are added in organic solvent, stirred under the conditions of 60-80 DEG C to
After being completely dissolved, continue to stir 1-2h, through being concentrated under reduced pressure into the content of organic solvent in 30-40%；
(3) into step 2, activated silica gel is added in solution, and 60-80 DEG C is continued to stir 1-2h, and adipic acid, polycaprolactone is added
Polyalcohol, 40-50 DEG C of stirring 1-2h stand 10-25min, and 20-30 DEG C is continued to stir 1-2h, 10-15 DEG C of standing 2-4h, at this time
Molecular film can gradually form completely, and be wrapped in the surface of silica gel particle, in being sent into low-temperature freeze dryer, -5-0 DEG C of low temperature freeze-dryings
1-2h removes remaining organic solvent to get to waterproofing agent.
The quality of the polyacrylic acid, hydroxymethyl cellulose, chitosan, activated silica gel, adipic acid, polycaprolactone polyol
Than being 1:2-3:2-3:6-7:0.5:1.
The organic solvent is the mixed solution of dichloromethane and methanol, volume ratio 5:1.
Polyacrylic acid, hydroxymethyl cellulose, chitosan contain more hydrophobic grouping and the structure with cellulose, to water
Molecule has good dredging property and repellency, has good water resistance using them as molecular film made of material.Adipic acid
Effect be adjust solution pH be acidity, polycaprolactone polyol is a kind of cryogenic film auxiliary agent, energy under the conditions of acidic low temperature
Enough help the formation of intermolecular generation polymerisation and molecular film.It, can be by molecular film fully, uniformly using silica gel as carrier
It is blended in coating, reaches best using effect.
A kind of blue tangerine line waterproof powdery paints applied on electric appliance, preparation method are：In accurate weighing formula
Each component raw material is placed in high-speed mixer mixing 8-10min；After material mixing, squeezed at a temperature of 90-100 DEG C with extruder
Go out；It is powder particle that average grain diameter is 30-33 microns to be crushed with pulverizer after extruded stock cooling is broken；Again with 150 mesh screens
Sieving, is finally packaged into finished product.
The beneficial effects of the invention are as follows：(1) present invention is made using polyacrylic acid, hydroxymethyl cellulose, chitosan of raw material
Molecular film waterproofing agent compared with general waterproofing agent, preparation process is simple, water resistance is good；(2) adipic acid, polycaprolactone polyol
Alcohol has good gain effect as coalescents, to the formation of molecular film；(3) molecular film in coating is anti-well in addition to having
Outside water effect, moreover it is possible to completely cut off the oxygen in air, have certain retarding action to colour fading, the corrosion of coating.
