Abstract
The invention discloses a thin coating powder paint which is composed of the following components in percentage by weight: 24-26% of epoxy resin, 20-25% of titanium white, 18-24% of barium sulfate, 14-17% of calcium carbonate, 8-10% of pigment and filler, 5-7% of leveling agent, 0.5-1% of benzoin and 0.5-1% of degasifier. The paint coating has favorable leveling property; and on the premise of maintaining the covering power, strength, gloss and other properties of the coated film unchanged, the coating thickness is reduced, thereby shortening the curing time and lowering the cost. The product adopts the existing production equipment, is simple in operational procedure, and is widely suitable for decoration and corrosion resistance of household appliances, metal furniture, office equipment, instruments and apparatuses, and mechanical equipment.
Description
Technical field
The present invention relates to paint field, particularly a kind of shallow layer powder coating.
Background technology
Thermosetting powder coating(s) refers to using thermosetting resin as filmogen, add the solidifying agent of crosslinking reaction can form not molten hard coat after heating, temperature is high again, this coating can only be decomposed, and can be not softening as thermoplastic resin coating, the resin adopting due to thermosetting powder coating(s) is the prepolymer that the polymerization degree is lower simultaneously, its molecular weight is lower, so the levelling property of coating is better, have ornamental preferably, and low-molecular-weight prepolymer is after solidifying, can form the macromole of cross-linked network, coating has better preservative property and mechanical property.
But at instrument, household electrical appliance, the fields such as mechanical means, coating must be to the future development of shallow layer, shallow layer is had relatively high expectations to powder-type coating, as low in resin melting viscosity, colo(u)rant dispersion performance is good, strong covering power, painting material granularity is little, dry powder good flowing properties etc., particularly for white powder coating, ensure that its film reaches the protection of standard to dark metal surface, modify, mechanic effect, just must make its film reach certain thickness, generally 70-80 μ m at present, this is compared with solvent type coating coating thickness 20-30 micron, difficulty of construction and production cost are increased beyond doubt, be unfavorable for the development of powder-type coating, therefore, develop a kind of shallow layer, levelling property is strong, the powder coating that opacifying power is good, it is this area technical barrier urgently to be resolved hurrily always.
Summary of the invention
For the problems referred to above, the shallow layer powder coating of a kind of strong covering power, good mechanical property is provided, the present invention is achieved in that
A kind of shallow layer powder coating, it forms component and weight ratio is: epoxy resin 24-26%, titanium dioxide 20-25%, barium sulfate 18-24%, calcium carbonate 14-17%, color stuffing 8-10%, flow agent 5-7%, st-yrax 0.5-1%, air release agent 0.5-1%.
Preferably, in the present invention, described flow agent is alkyl-modified organo-siloxane.
Preferably, in the present invention, described epoxy resin is E-12.
Paint coatings good leveling property of the present invention, keep film opacifying power, intensity, gloss, etc. on the constant basis of performance, attenuate coat-thickness, shorten set time, reduce costs, product of the present invention adopts existing equipment, and operating process is simple, is widely used in the decoration, anticorrosion of household electrical appliance, art metal furniture, office equipment, instrument, mechanical means.
