Disclosure of Invention
The invention aims to provide a novel coating agent, in particular to a novel phosphate coating agent, which solves the problems of unstable use performance of the coating agent and poor bonding force and adhesion force after coating.
In order to achieve the above object, the present invention provides a phosphate coating agent comprising:
phosphoric acid, nitric acid, zinc oxide, a surfactant, a metal chelating agent, nickel sulfate and water.
Preferably, the phosphate coating agent comprises:
25-35 wt% of phosphoric acid, 5-15 wt% of nitric acid, 10-20 wt% of zinc oxide, 3-7 wt% of surfactant, 3-7 wt% of metal chelating agent, 5-15 wt% of nickel sulfate and 20-30 wt% of water.
As a further preferred embodiment, the phosphate coating agent comprises:
28-32 wt% of phosphoric acid, 8-12 wt% of nitric acid, 13-17 wt% of zinc oxide, 4-6 wt% of surfactant, 4-6 wt% of metal chelating agent, 8-12 wt% of nickel sulfate and 22-28 wt% of water.
As a further preferred embodiment, the phosphate coating agent comprises:
30 wt% of phosphoric acid, 10 wt% of nitric acid, 15 wt% of zinc oxide, 5 wt% of a surfactant, 5 wt% of a metal chelating agent, 10 wt% of nickel sulfate and 25 wt% of water.
Most preferably, the phosphate coating agent has a composition of:
30 wt% of phosphoric acid, 10 wt% of nitric acid, 15 wt% of zinc oxide, 5 wt% of a surfactant, 5 wt% of a metal chelating agent, 10 wt% of nickel sulfate and 25 wt% of water.
Preferably, the surfactant is an anionic surfactant and/or a nonionic surfactant.
Preferably, the surfactant is at least one selected from linear alkyl benzene sulfonic acid sodium salt, fatty alcohol-polyoxyethylene ether sodium sulfate, fatty alcohol-polyoxyethylene ether ammonium sulfate, lauryl alcohol sodium sulfate, lauroyl glutamic acid, nonylphenol polyoxyethylene ether, stearic acid monoglyceride, lignosulfonate, heavy alkylbenzene sulfonate, alkyl polyether and fatty alcohol-polyoxyethylene ether.
Preferably, the metal chelating agent is at least one selected from the group consisting of ethylenediaminetetraacetic acid, nitrilotriacetic acid, and diethylenetriaminepentaacetic acid.
More preferably, the metal chelating agent is selected from ethylenediaminetetraacetic acid.
The metal chelating agent can contain metal ions into the chelating agent through the strong binding action of the chelating agent molecules and the metal ions, so that the metal ions are changed into stable compounds with larger molecular weight, the metal ions are prevented from acting, and the metal chelating agent can be used for detoxifying, printing and dyeing, scale inhibition and other aspects. Complex ion counterions (also called complex ions) that are formed by combining a simple positive ion (called the central ion) and several neutral molecules or ions (called ligands), and compounds containing the counterions are called coordination compounds. The central ion of the complex is combined with the ligand through a coordination bond. A coordination bond is a special covalent bond, and a common covalent bond is formed by two bonding atoms respectively donating an electron to form a common electron pair, while in the coordination bond, only one atom provides an electron pair, and the other atom provides an empty orbital. For the sake of distinction, covalent bonds are denoted by "-" as H +. H ═ H: h (H — H), coordination bonds are still denoted by "←", arrows pointing to atoms providing empty orbitals, such as Cu + NH3 ═ CuNH3(Cu ← NH 3). If there is only one coordinating atom in the ligand, only one coordination bond can be formed between the central ion and the ligand. Some ligands contain more than two coordinating atoms, and when two atoms are separated by two to three other non-coordinating atoms, the ligand can form more than two coordination bonds with the central ion (or atom) at the same time, and form a special structure comprising two coordinating five-or six-membered rings, and the complex is called chelate. The chelate is more stable than the general complex.
The invention has the beneficial effects that:
the invention provides a novel coating agent, in particular to a novel phosphate coating agent, which solves the problems of unstable use performance of the coating agent and poor bonding force and adhesion force after coating.
Additional features and advantages of the invention will be set forth in the detailed description which follows.
