Abstract
The invention discloses a spraying type comprehensive phosphate treating agent for a cold-rolled sheet workpiece spraying coating. The spraying type comprehensive phosphate treating agent comprises the following components in percent by mass: 15-45 percent of phosphoric acid, 1-2 percent of zinc oxide, 1-2 percent of tartaric acid, 0.1-0.5 percent of thiourea, 1-8 percent of a normal temperature steel surface treating agent, 1-2 percent of ethylene glycol monobutyl ether, 1-3 percent of a soak degreasing special surface active agent, 1-3 percent of a spray degreasing special low-foam surface active agent, 1-2 percent of JFC (fatty alcohol-polyoxyethylene ether) and the balance of water. A preparation method of the spraying type comprehensive phosphate treating agent comprises the following steps of: adding the water into a reaction kettle, starting a stirrer, controlling the rotating speed to be 60 turns/min; then sequentially and slowing adding the phosphoric acid, the zinc oxide, the tartaric acid, the thiourea, the normal temperature steel surface treating agent, the ethylene glycol monobutyl ether, the soak degreasing special surface active agent, the spray degreasing special low-foam surface active agent and the JFC into the reaction kettle, wherein the zinc oxide and the tartaric acid are added and then are stirred for at least 30min, and the remained raw materials are added and then are stirred for at least 10min; and finally, continuously stirring until a solution is light yellow transparent liquid.
Description
Technical field
The present invention relates to a kind of metal transformation treating agent and preparation method, especially a kind of simple to operate, can improve sticking power between workpiece surface and the spray-on coating, improve the spray-on coating erosion resistance and enhance productivity
The application of cold-reduced sheet Workpiece painting with the comprehensive phosphate treatment agent of spraying type and preparation method.
Background technology
Metal component surface is because of grease, floating rust, heavily rust, oxide skin and welding high-temperature oxide etc., therefore before the art breading such as spray-coating, all require above-mentioned oily scale etc. is disposed, and mostly process by phosphate conversion, the phosphate conversion film that makes its Surface Creation one deck have certain roughness, porousness, adsorptivity is to strengthen the workpiece surface rotproofness, to improve workpiece surface and the sticking power that is coated with interlayer or other organic surface treatment interlayers.At present, the spray-coating pre-treatment for the cold-reduced sheet workpiece is to adopt following technique basically: drill traverse degreasing phosphate comprehensive treating process → washing → passivation → oven dry → spray-coating.But drill traverse degreasing phosphate comprehensive treating process also is not suitable for large-scale workpiece (be 1.2 such as thickness, the round cold-reduced sheet workpiece of diameter of phi 1200), and not only complicated operation, and efficient is extremely low, sometimes also the problem that spray-on coating comes off can occur.
Summary of the invention
The present invention is in order to solve the existing above-mentioned technical problem of prior art, provide a kind of simple to operate, can improve sticking power between workpiece surface and the spray-on coating, improve the spray-on coating erosion resistance and the cold-reduced sheet Workpiece painting application of enhancing productivity with the comprehensive phosphate treatment agent of spraying type and preparation method.
Technical solution of the present invention is: the application of a kind of cold-reduced sheet Workpiece painting is characterized in that being made of the component of following mass percent: phosphatase 11 5 ~ 45%, zinc oxide 1 ~ 2%, tartrate 1 ~ 2%, thiocarbamide 0.1 ~ 0.5%, normal temperature steel surface processing agent 1 ~ 8%, ethylene glycol monobutyl ether 1 ~ 2%, soak degreasing special surfactant 1 ~ 3%, the special-purpose low-foaming surfactant 1 ~ 3% of spray degreasing, JFC 1 ~ 2% and water surplus with the comprehensive phosphate treatment agent of spraying type.
The application of a kind of above-mentioned cold-reduced sheet Workpiece painting is with the preparation method of the comprehensive phosphate treatment agent of spraying type, it is characterized in that carrying out as follows: the water that will calculate first weighing joins in the reactor, start agitator, the control rotating speed is 60 rev/mins, then will calculate successively the phosphoric acid of weighing, zinc oxide, tartrate, thiocarbamide, the normal temperature steel surface processing agent, ethylene glycol monobutyl ether, the soak degreasing special surfactant, the special-purpose low-foaming surfactant of spray degreasing, JFC joins in the reactor slowly, stirred at least 30 minutes respectively after wherein zinc oxide and tartrate add, need after all the other raw materials add to stir at least 10 minutes, continue at last to be stirred to solution and be light yellow transparence liquid.
The present invention can be before the application of large-scale cold rolling plate Workpiece painting, only needing spray under the normal temperature to clean can be thoroughly and remove fast the dust, greasy dirt etc. of cold rolling workpiece surface, and at cold rolling workpiece surface formation conversion film, have the functions such as oil removing, rust cleaning, passivation, simple to operate, save electric energy, can reduce the workpiece tooling cost, improve sticking power between cold-rolled steel sheet and the spray-on coating, improve the corrosion resistance nature of spray-on coating and significantly improve cleaning efficiency.
