Abstract
The invention discloses a water-washing-free spraying comprehensive treating agent before spray coating of an electronic scale bed plate and a preparation method. The comprehensive treating agent is prepared from the raw materials in percentage by weight: 10-22% of phosphoric acid, 1-1.5% of zinc oxide, 1-2% of tartaric acid, 0.5-1.5% of phytic acid, 10-30% of SP-16, 1-4% of QYL-10F, 1-3% of isopropanol, 0.6-1.6% of ethylene glycol monobutyl ether, 0.6-1.2% of defoaming agent and the balance of water. The preparation method comprises the steps of: adding calculated and weighed water to a reaction kettle, starting a stirrer and controlling the rotation speed at 80 rpm, then sequentially and slowly adding calculated and weighed phosphoric acid, zinc oxide, SP-16, tartaric acid, phytic acid, QYL-10F, isopropanol, ethylene glycol monobutyl ether and defoaming agent to the reaction kettle, stirring for 10-20 min after each raw material is added, continuing stirring until the solution is transparent light-green liquid after all raw materials are added, discharging and packaging.
Description
Technical field
The present invention relates to agent of a kind of metal spraying Coating Pretreatment and preparation method, especially a kind ofly exempt from degreasing washing, but fast filming, guarantee to exempt from washing spray comprehensive treatment agent and preparation method before the electronic platform scale seat board spray-coating of coating quality.
Background technology
Metal works all should carry out the phosphatization conversion processing to its surface before spray-coating, make it generate the phosphate conversion film.Its effect is to make the coating protecting layer on surface with metallic matrix good combining arranged on the one hand; In the time of can or being corroded the medium eating thrown in the local damage of topcoating protective layer on the other hand; Protecting metallic matrix; Exempt from the direct corrosion of medium, prevent the metallic corrosion expansion under the topcoating protective layer metallic matrix.For this reason as the phosphatization conversion film of spray-coating bottom, require that rete is fine and close, quality is even, crystal grain is tiny, thickness is moderate.According to bibliographical information, spray-coating can improve 12 times than the solidity to corrosion of direct spray-coating after the process conversion processing film forming of metallic surface.At present; The treatment process of the professional plant of electronic platform scale before to electronic platform scale seat board spray-coating is: artificial mechanism polishing → manual wipping surface → dress is suspended on the automation line → enters into the electrostatic powder coating coating process; Promptly the seat board surface of steel plate is carried out the artificial mechanism polishing; Dress is suspended on the chain of spray-coating automation line then, directly electrostatic powder coating application.The unavoidable secondary oxidation that produces in electronic platform scale seat board surface after polishing is handled, add polishing after residual dust be difficult to Ex-all, so can not guarantee the technological effect of spray-coating, to such an extent as to all there is serious obscission in electronic platform scale seat board surface sprayed coating.Because existing phosphating process all needs degreasing, after washing and phosphatization after washing etc. eliminate rust, descale; Otherwise the accumulation of remained on surface liquid will be difficult to guarantee the surface quality of Workpiece painting application; The construction of automation lines such as washing is complicated, cost is high, long in time limit and increase; For this reason, the professional plant of existing electronic platform scale still continues to use the production technique that tradition falls behind.
Summary of the invention
The present invention is in order to solve the above-mentioned technical problem of existing in prior technology, to provide a kind of and exempt from degreasing, washing, but fast filming, guarantees to exempt from washing spray comprehensive treatment agent and preparation method before the electronic platform scale seat board spray-coating of coating quality.
Technical solution of the present invention is: exempt from washing spray comprehensive treatment agent before a kind of electronic platform scale seat board spray-coating, it is characterized in that raw materials used and mass percent following:
