Description
Technical field
The present invention relates generally to a kind of water-borne coatings, relates in particular to a kind of environment-friendly type aqueous rust proof paint and preparation method thereof.
Background technology
In order to protect iron and steel not corroded, prolong its work-ing life, iron and steel is carried out corrosion-proof coating become a kind of most economical and effective means.In order to obtain the superior corrosion resistance energy, must remove the iron rust on the steel clean before the application, otherwise can cause paint film and preservative effect very poor owing to the continuous expansion of iron rust, therefore, the processing of rust removing of iron rust is the important component part of coating process, to the success or failure decisive role of corrosion-proof coating.But many heavy constructions, bridge, boats and ships, etc. the steel structure member of complexity in maintenance process owing to be subjected to the restriction of execution conditions, be difficult to adopt the mechanized construction method, can only adopt craft or power tool to eliminate rust, its result must have the residual of iron rust and various corrosion products, and that the difficult quality that causes eliminating rust is guaranteed, constructs is difficult, expense is huge.Rust cleaning is a kind of ten minutes heavy work, not only expends a large amount of man-hours but also increase expense.It is reported that steel plate application expense allocation ratio is: surface derusting 42%, construction 30%, coating 19%.Present domestic anticorrosion of steel structure is still continued to use the old technology of carrying out application after the sandblast, though preservative effect is better, but sandblast, ball blast technology also exist complex structural member many shortcomings such as dead angle, consume electric power height, dust pollution, sound pollution, cost height are arranged, so the on rust paint that preparation can directly be constructed at the rust face is very important.
Traditional process using phosphoric acid is as transforming agent, although phosphoric acid can make corrosion be converted into phosphatize phosphate coat, because hydrogen is separated out, paint film easily bubbles, and causes loss of adhesion.It relies on the composite organic acid group of grafting on the submicron macromolecule micelle, iron rust is reduced into the passivation composition with antirust ability, rearranging of molecular level takes place at whole metallic matrix in macromolecule micelle simultaneously, form the big net of a densification by the intersection film forming, because rete directly is combined by chemical bond with base material, and the molecular level of rete rearranges to make and does not almost have the space between particle, therefore rete has high closeness, high rust cleaning performance, high adhesive force does not thoroughly cause in a short time anticaustic problem thereby thoroughly solve secondary problem of rustiness before the rust cleaning back application and rust cleaning.
Compound poly-hydroxy organic molecule is called coordination or chelating with the process of metallic surface combination securely.In this technology, be coated on when film forming, the aligning of high molecular polymer molecule of the metallic surface of having got rusty: on the polymer chain numerous anchorings roll into a ball an end and base material Fe or and the main component Fe (OH) 2 of iron rust Fe (OH) 3, FeO iron ion bonding such as Fe2O3 form high stability chemical coordination key, the other end film forming forms typical hydrophobic barrier.
