Description
Technical field
The present invention relates to a kind of epoxy resin and zinc-enriched heavy anti-corrosive and preparation method thereof, belong to the powder coating technical field of electrostatic coating.
Background technology
Double antiseptic powder coating is one of powder coating developing trend, double antiseptic powder coating mainly improves the anti-corrosion capability of powder coating by binder resin modification, antirust color stuffing at present, take simultaneously thickly to be coated with, the constructional method of overbrushing layer or compound coating, to realize the anticorrosion purpose of weight of coating.
Utilize the anodic oxidation of metallic zinc to protect this principle of steel substrate, people develop zinc-rich coating and organic zinc-rich primer, are successfully applied in the anticorrosive construction of all kinds of iron structures, and have obtained unusual effect.But the same with powder coating with common paint, existing all kinds of zinc rich primers obviously exist coating machine poor performance, construction cost height, environmental pollution and preservative effect defective not fully up to expectations.
Summary of the invention
The purpose of this invention is to provide a kind of coating machine excellent performance, construction cost is low and efficient, exsertile epoxy resin and zinc-enriched heavy anti-corrosive of preservative property and preparation method thereof.
The present invention realizes with following technical scheme: epoxy resin and zinc-enriched heavy anti-corrosive is to be that raw material is made by Resins, epoxy, novolac epoxy, zinc powder, solidifying agent, curing catalyst, flow agent, toughner, air release agent, flow improver additive, filler.The weight percent of various raw materials is: Resins, epoxy 25-60%, novolac epoxy 2-15%, solidifying agent 3-10%, curing catalyst 0.05-0.5%, flow agent 503 1-3%, toughner PVB 0.2-2%, air release agent 0.1-0.5%, flow improver additive 0.1-0.2%, zinc powder 20-50%, filler 0-20%.
The usage percentage of each raw material is that the contriver draws on a large amount of experimental basis, has good effect in above-mentioned amount ranges.
Zinc powder among the present invention is a flakey, particle diameter 1-20 μ m.
Solidifying agent among the present invention is the phenols hardener for epoxy resin.
Curing catalyst among the present invention is imidazoles or ring miaow based epoxy resin solidifying agent.
Air release agent among the present invention is a micro mist wax.
Flow improver additive among the present invention is aerosil or aluminum oxide C.
Filler among the present invention is a ultra-fine barium sulfate.
Flow agent among the present invention is an acrylic polyester;
Toughner among the present invention is PVB.
The preparation method of epoxy resin and zinc-enriched heavy anti-corrosive of the present invention is as follows:
Employing melt extrude hybrid system or fusion high-speed stirring hybrid system with the dispersed mixture of zinc powder, Resins, epoxy, novolac epoxy, flow agent carry out the fusion dispersion, pre-dispersed mixture is made in the roll-in cooling in flakes, then with pre-dispersed mixture and solidifying agent, curing catalyst, toughner, air release agent, flow improver additive, filler together through premix → extrude → compressing tablet → abrasive dust → sieve epoxy resin and zinc-enriched heavy anti-corrosive.
Among the present invention melt extrude hybrid system be blending dispersion thing with zinc powder, Resins, epoxy, novolac epoxy, flow agent be added in the screw extrusion press extrude, more broken thing melt extruded once more behind the compressing tablet, fragmentation, compressing tablet, fragmentation, so repeat to melt extrude, compressing tablet, broken operation repeatedly make pre-dispersed mixture, preceding warm 90-100 ℃ of forcing machine, warm 120-130 ℃ of back, material melt extrudes, compressing tablet, broken repetitive operation accumulative total 2-5 time, mixing of materials accumulated time 60-300s.
Fusion high-speed stirring hybrid system of the present invention is that the dispersed mixture of Resins, epoxy, novolac epoxy, flow agent, zinc powder or independent the adding are successively had in the stainless steel cauldron of mechanical stirring, thermometer, heating jacket, material is heated to 130-160 ℃ to be melted until resin, and maintain 130-160 ℃, simultaneously with the material high-speed stirring, at 130-160 ℃ of following dispersed with stirring 0.5-1h, pour cooling, fragmentation in the big aluminum square position then into, be pre-dispersed mixture.
The invention has the beneficial effects as follows:
Powder coating of the present invention adopts the electrostatic spraying constructional method to act on to reach Sa2.5 through sandblast or ball blast pre-treatment rear surface roughness that (ISO 8501.1,1988) on the above steel substrate that requires, fully solidify through 200 ℃, naturally cool to room temperature, after placing 24h, measure coating performance, its coat-thickness 50-80 μ m.Its salient features characterizes as follows:
Salt-fog test is measured by the FQY-010 type salt-spray cabinet that laboratory apparatus factory in Shanghai produces, artificial accelerated aging test is measured by the Q-UV artificial accelerated aging test instrument that U.S. ATLAS company produces, thickness is measured with the two probe thickness testers of 600B type that German BYK company produces, sticking power is measured by GB/T 9286-1998 regulation, and shock strength is measured by GB/T 1732-1993 regulation.Its test result is: every index is all above the industry standard HG/T 3668-2000 that has zinc rich primer now, and the coating salt-fog resistant test was above 2000 hours.Practical application shows that this epoxy resin and zinc-enriched heavy anti-corrosive can protect steel construction to avoid the etch of all kinds of corrosive mediums for a long time, and effect obviously is better than existing zinc rich primer.
Production of the present invention and using method are simple, and be nontoxic, pollution-free, the abundant and low price in starting material source.
