A surface treated copper foil with improved adhesion to the insulating resin of a copper-clad laminate for higher frequency applications contains a copper foil provided with a heat-resistant layer and an olefin-based silane coupling agent layer sequentially on at least one side thereof. An anticorrosive treatment may be performed after the heat resistance treatment. The copper foil is preferably an electrolytic copper foil, and these layers can be provided on the S side and / or the M side thereof. The copper foil has an adequate adhesive strength, even without the roughening treatment that has been performed in the past. A film of zinc, zinc-tin, zinc-nickel, zinc-cobalt, copper-zinc, copper-nickel-cobalt, or nickel-cobalt can be used favorably as the heat-resistant layer, and a film that has undergone a zinc-chromate or a chromate treatment can be used favorably as the anticorrosive layer.

Corrosion-Resistant Epoxy Nanocomposite Coatings containing Submicron Emeraldine-Base Polyaniline and Organomodified Montmorrilonite
InactiveUS20100010119A1Good dispersionImprove barrier propertiesMaterial nanotechnologyLayered productsEpoxySalt spray test
Disclosed is a method of preparation of corrosion-resistant epoxy coatings. The coating composition contains two main corrosion resistant factors: The first one was Eemeraldine-Base polyaniline (EB-PANi), dissolved in the aminic hardener of epoxy. The other one was montmorrilonite clay, dispersed or exfoliated in the base component of epoxy resin. The hardener composition was prepared via dissolution of EB-PANi in functional amines like 3-(aminomethyl)-3,5,5-trimethylcyclohexan-1-amine adopting sonication and nanoscale filtering methods. The base component was prepared via gradual charging of MMT clay in epoxy resin via high-shear mixing plus sonication method. The morphology of the coatings during different stages of preparation was studied by optical microscopy and scanning electron microscopy and TEM. The corrosion-protective performance of the resultant coatings was evaluated by electrochemical impedance spectroscopy and salt spray tests. The results were compared with those of conventional epoxy zinc-chromate and neat resin coatings. Superior corrosion resistance was achieved via dissolution of 0.5-2.5 wt % of EB-PANi in the aminic hardener and 2-4 WT % of organomodified MMT in base component of coating.

Fastener surface treatment method
InactiveCN108187992ABright appearanceImprove bindingPretreated surfacesCoatingsCollision resistanceDip-coating
The invention discloses a fastener surface treatment method. The method comprises the following steps of S1, shot blasting, wherein shot blasting is carried out on a fastener in a shot blasting machine, and rusting is removed; S2, dip-coating, wherein the fastener subjected to shot blasting is put into a coating solution containing zinc chromate for immersion coating; S3, centrifuging, wherein thepower is 35-40 Hz, the time is 50 + / - 10 seconds; S4, baking, wherein baking and curing are carried out by adopting a mesh belt type gas stove; S5, discharging, wherein the baked fastener is taken out and placed well; S6, secondary immersion coating, wherein the fastener which is baked and discharged is put into the coating solution containing zinc chromate for immersion coating; S7, secondary centrifuging, wherein power is 35-40 Hz, and the time is 50 + / -10 seconds; S8, secondary baking, wherein the baking and curing are carried out by adopting the mesh belt type gas stove; and S9, discharging, wherein the fastener after secondary baking is taken out, and then baking and curing are carried out after the surface of the fastener is coated with the organic resin (repeated twice). Accordingto the fastener surface treatment method, the product can be bright in appearance, uniform in color and luster, high in collision resistance and good in anti-corrosion performance.
