Abstract
The invention discloses protective anti-corrosion no-clean flux which comprises an organic solvent, natural resin, a surfactant, an organic acid activator, a preservative, a corrosion inhibitor, a leveling agent and an anti-sag agent, wherein the organic solvent is methyl ethyl ketone; the natural resin is rosin; the surfactant is polyoxyethylene stearate; the organic acid activator is fumaric acid; the preservative is pentaerythritol oleate; the corrosion inhibitor is benzotriazole; the leveling agent is carboxymethyl cellulose; the anti-sag agent is modified bentonite. Comprising the organic solvent, the natural resin, the surfactant, the organic acid activator, the preservative, the corrosion inhibitor, the leveling agent and the anti-sag agent, the protective anti-corrosion no-clean flux has the advantages of being free of cleaning, clean to use, and high in corrosion resistance and use effect.
Description
Technical field
The present invention relates to scaling powder field, be specifically related to a kind of protection inhibition no-clean scaling powder.
Background technology
In decades, produce in soldering process process at electronic product, the abietic resin system scaling powder primarily of the activating agent of rosin, resin, halide, additive and organic solvent composition is used much more general. although this kind of scaling powder solderability is good, cost is low, but postwelding remains object height. its residue contains halide ion, progressively can cause the problems such as electrical insulation properties decline and short circuit.Solder surface can be caused to occur corrosion after long-time use, result of use is not good enough simultaneously.Therefore, research and develop a kind of scaling powder protecting the No clean of inhibition and become the problem instantly needing to be badly in need of solving.
Summary of the invention
The object of the present invention is to provide a kind of organic solvent, natural resin, surfactant, organic acid activator, anticorrisive agent, corrosion inhibiter, levelling agent and anti-sagging agent of adopting to form, there is No clean, use the protection inhibition no-clean scaling powder of the feature clean, anticorrosive property is strong, result of use is good.
Technical scheme of the present invention is, a kind of protection inhibition no-clean scaling powder, described protection inhibition no-clean scaling powder is by organic solvent, natural resin, surfactant, organic acid activator, anticorrisive agent, corrosion inhibiter, levelling agent and anti-sagging agent composition, described organic solvent is methyl ethyl ketone, described natural resin is rosin, described surfactant is polyoxyethylene carboxylate, described organic acid activator is fumaric acid, described anticorrisive agent is PETO, described corrosion inhibiter is BTA, described levelling agent is carboxymethyl cellulose, described anti-sagging agent is modified alta-mud, in described protection inhibition no-clean scaling powder, shared by each composition, parts by weight are respectively: described methyl ethyl ketone accounts for 47-53 part, described rosin accounts for 30-38 part, described polyoxyethylene carboxylate accounts for 6-10 part, described fumaric acid accounts for 12-15 part, described PETO accounts for 4-7 part, described BTA accounts for 5-8 part, described carboxymethyl cellulose accounts for 8-11 part, described modified alta-mud accounts for 13-16 part.
In a preferred embodiment of the present invention, in described protection inhibition no-clean scaling powder, shared by each composition, parts by weight are specially: described methyl ethyl ketone accounts for 48 parts, described rosin accounts for 31 parts, described polyoxyethylene carboxylate accounts for 7 parts, described fumaric acid accounts for 13 parts, and described PETO accounts for 5 parts, and described BTA accounts for 6 parts, described carboxymethyl cellulose accounts for 9 parts, and described modified alta-mud accounts for 14 parts.
