Description
Technical field
The present invention relates to epoxy coating preparation fields, and in particular to a kind of preparation side of exterior wall epoxy coating
Method.
Background technology
The high mechanical properties of epoxy resin have very strong cohesive force, and molecular structure is fine and close, and mechanical property is higher than phenolic aldehyde
The universal thermosetting resin such as resin and unsaturated polyester (UP)；The strong adhesive force of epoxy resin contains in epoxy resin solidifying system
Active greatly epoxy group, hydroxyl and ehter bond, amine key, ester bond isopolarity group, assign epoxy curing compound to metal, ceramics,
Glass, coagulation scholar, timber isopolarity base material are with excellent adhesive force；The cure shrinkage of epoxy resin is small, generally 1%~
2%.It is that (phenolic resin is 8%~10% to one of kind of cure shrinkage minimum in thermosetting resin, unsaturated polyester resin
It is 4%~6%, organic siliconresin is 4%~8%), linear expansion coefficient also very little, generally 6 × 10-5/ DEG C, so body after solidification
Product variation is little；The good manufacturability of epoxy resin, when epoxy resin cure, do not generate low molecular weight volatile object substantially, so can be low
Molded or contact is molded, can coordinate the rings such as solvent-free manufacture, high solid, powdery paints and water paint with various curing agent
Guarantor's type coating；The excellent electrical insulating property of epoxy resin.Epoxy resin be the best kind of thermosetting resin intermediary electrical property it
One；The stability of epoxy resin is good, and chemical proof is excellent, and the epoxy resin without impurity such as alkali, salt is unlikely to deteriorate, as long as
It stores proper (seal, do not make moist, do not meet high temperature), storage period is 1 year.If examining qualification still to can be used after exceeding the time limit, epoxy is solid
Compound has an excellent chemical stability, the performances of a variety of dielectric corrosions such as alkaline-resisting, sour, salt better than unsaturated polyester resin,
The thermosetting resins such as phenolic resin, therefore epoxy resin is largely used as anticorrosion priming paint, and because epoxy resin cured product is in three-dimensional
Reticular structure, and the dipping of ability oils etc., are widely used in the integral tank inboard wall lining etc. of oil groove, oil tanker, aircraft；Epoxy
The heat resistance of the epoxy curing compound of resin is generally 80~100 DEG C, and the heat resistant variety of epoxy resin is up to 200 DEG C or higher.
But because typically containing fragrant ehter bond in epoxy resin, solidfied material degradable chain rupture after solar radiation, so
Common bisphenol A type epoxy resin solidfied material solarization outdoors, easily tarnishes, gradual dusting, therefore should not be used as open air
Finishing coat；Again because having hydroxyl in epoxy resin, such as deal with improperly, water-resistance property of coating can be very poor, also causes it that should not be used as open air
Finishing coat.The present invention is by improving factory formula and improving process of preparing so that epoxy coating can be used as exterior wall
Coating.
Invention content
It is an object of the invention to overcome existing the deficiencies in the prior art, a kind of exterior wall epoxy coating is disclosed
Preparation method, the present invention easily tarnishes for existing epoxy resin coating after solar radiation, gradual dusting and waterproof
Property difference the technical problems such as outdoor finishing coat should not be used as to be improved, disclose a kind of preparation side of exterior wall epoxy coating
Method；

It is ground to fineness≤25 μm in grinder, adds micaceous iron oxide gray and carries out high speed dispersion, adjusts viscosity with cyclohexanone, that is, makes
Obtain exterior wall epoxy coating.
Further, in order to suitably increase the number-average molecular weight of product epoxy resin, 500~700 can be reached
Number-average molecular weight, the plasticizer in step 1 select di-sec-octyl phthalate, BBP(Butyl Benzyl Phthalate or O-phthalic
Dioctyl phthalate.
Further, in order to enable the corrosivity of exterior wall epoxy coating acid and alkali-resistance obtained, in step 2
Preservative selects isothiazolinone derivatives；In order to which epoxy resin has certain adhesivity, the curing agent in step 2 is selected
Base triamine, trimethyl diamines or the triethylene tetramine of trimethylhexamethylenediamine, two；It is outer in order to make the later stage be prepared
Wall epoxy coating is capable of the irradiation of antisum, prevents powder of detached, light stabilizer select O-hydroxyl-diphenyl ketone class or
Person's Benzotriazole Ultraviolet Stabilizer.
Further, in order to ensure the quality for the coating being prepared, prevent the settlement influence of pigment and material from using, step
Anti-settling agent in rapid three selects polyamide wax.
Further, in order to ensure that the coating being prepared has good glossiness and finish, the sulphur in step 3
The fineness of sour barium, talcum powder and micaceous iron oxide gray is 450 mesh.
Further, in order to ensure coating finished product can have enough fineness, step 3 high speed dispersion rate control
System is in 450~600r/min.
The present invention has the advantages that：Exterior wall prepared by the present invention has glossiness good, anti-with epoxy coating
Aging is strong, the characteristics of having excellent water-resistance, and is not easy to fade through sunshine, dusting, and corrosion resistance is strong, is suitable for the finishing coat of exterior wall.
