Abstract

The invention discloses a novel plastic processing phosphating solution and a preparation method thereof. The novel plastic processing phosphating solution comprises liquid raw materials and solid raw materials, wherein the liquid raw materials include phosphoric acid, nitric acid and water; the weight percentage of the phosphoric acid is 20-40%; the weight percentage of the nitric acid is 20-40%; the weight percentage of the water is 20-40%; the solid raw materials include zinc oxide, zinc nitrate hexahydrate, calcium nitrate tetrahydrate, citric acid, tartaric acid, manganous dihydrogen phosphate, sodium molybdate, zinc dihydrogen phosphate and sodium dihydrogen phosphate; the weight percentage of the zinc oxide is 5-10%; the weight percentage of the zinc nitrate hexahydrate is 2-5%. A layer of phosphating composite film can be formed on the surface of metal within a short time, and the drawing property of the surface of the metal is improved obviously.

Description

technical field [0001] The invention relates to a phosphating solution and a preparation method thereof, in particular to a novel plastic processing phosphating solution and a preparation method thereof. Background technique [0002] Iron and steel phosphating is mainly used for corrosion protection and base film for paint. The existing phosphating solution cannot form a layer of phosphating composite film on the metal surface in a short time. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a novel plastic processing phosphating solution and its preparation method, which can form a layer of phosphating composite film on the metal surface in a short time, and obviously improve the drawing performance of the metal surface. [0004] The present invention solves the problems of the technologies described above through the following technical solutions: a novel plastic processing phosphating solution, characterized i...
