Abstract
The invention discloses a normal temperature comprehensive treating agent used before spraying and coating a cold-roll steel sheet. The normal temperature comprehensive treating agent comprises the components in percentage by weight as follows: 16%-26% percent of ammonium dihydrogen phosphate, 10%-33% percent of ammonium bifluoride, 1%-2% percent of tartaric acid, 1%-1.5% percent of ammonium citrate, 0.1%-0.8% percent of ammonium molybdate, 1%-8% percent of a low-foaming surface active agent special for spray degreasing, 1%-2% percent of a low-foaming surface active agent special for heavy oil removing spray degreasing, 0.1%-0.5% percent of an antifoaming agent, and the balance of water. The normal temperature comprehensive treating agent is prepared by the following steps that firstly water is added into a reaction kettle, a stirrer is started, the rotating speed is controlled at 60 revolutions per minutes, then the ammonium dihydrogen phosphate, the ammonium bifluoride, the tartaric acid, the ammonium citrate, the ammonium molybdate, the low-foaming surface active agents special for Y-33 spray degreasing, the low-foaming surface active agent special for Y-35 spray degreasing and the antifoaming agent are sequentially and slowly added into a reaction kettle, the constant stirring is performed for 10 minutes when each raw material is added, and finally the stirring is continuously performed until a solution is in a pale yellow and transparent liquid state.
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, save electric energy, be beneficial to environmental protection, can improve sticking power between workpiece surface and the spray-on coating, improve the preparation method of normal temperature comprehensive treatment agent before the cold-rolled steel sheet spray-coating of spray-on coating erosion resistance.
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, used comprehensive treatment agent all needs heat treatment basically before the cold-rolled steel sheet spray-coating, complicated operation not only, and increase product cost because wasting a large amount of electric energy, nonetheless, also the problem that spray-on coating comes off can appear.
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, be beneficial to environmental protection, can improve sticking power between workpiece surface and the spray-on coating, improve the preparation method of normal temperature comprehensive treatment agent before the cold-rolled steel sheet spray-coating of spray-on coating erosion resistance.
Technical solution of the present invention is: normal temperature comprehensive treatment agent before a kind of cold-rolled steel sheet spray-coating is characterized in that being made of the component of following mass percent: primary ammonium phosphate 16 ~ 26%, ammonium bifluoride 10 ~ 33%, tartrate 1 ~ 2%, ammonium citrate 1 ~ 1.5%, ammonium molybdate 0.1 ~ 0.8%, the special-purpose low-foaming surfactant 1 ~ 8% of spray degreasing, except the special-purpose low-foaming surfactant 1 ~ 2% of heavy oil spray degreasing, defoamer 0.1 ~ 0.5% and water surplus.
The preparation method of normal temperature comprehensive treatment agent before a kind of above-mentioned cold-rolled steel sheet spray-coating, 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 primary ammonium phosphate of weighing, ammonium bifluoride, tartrate, ammonium citrate, ammonium molybdate, the special-purpose low-foaming surfactant of spray degreasing, except the special-purpose low-foaming surfactant of heavy oil spray degreasing, defoamer joins in the reactor slowly, a kind of raw material of every adding needs continuously stirring 10 minutes, continues at last to be stirred to solution and is light yellow transparence liquid.
The present invention can be before the cold-rolled steel sheet spray-coating, removes at normal temperatures the dust, greasy dirt of surface of cold-rolled steel plate etc., and forms conversion film in surface of cold-rolled steel plate, has the functions such as oil removing, rust cleaning, passivation.Simple to operate, be beneficial to environmental protection, can improve the sticking power between cold-rolled steel sheet and the spray-on coating and improve the corrosion resistance nature of spray-on coating.
