Abstract

The invention discloses an environmentally-friendly metal primer. A preparation method of the metal primer includes: (1) adding graphite to water, stirring at 1200-1500r / min, adding sodium carboxymethyl cellulose and continuing to stir to prepare a graphite solution A; (2) adding epoxy resin, polyethylene glycol modified amino resin and polyacrylic acid polydimethylsiloxane to ethanol, stirring at1000r / min till the solid dissolves, then adding zinc yellow, carbon black and fumed silica and continuing stirring evenly to prepare a solution B; (3) adding the solution A slowly to the solution B under the stirring condition of 1500r / min and stirring uniformly to prepare slurry; (4) grinding and filtering the slurry to obtain the primer. The primer has simple process, the adopted solvents are environmentally friendly, the graphite and the zinc yellow in the process formula achieve an anti-corrosive effect, and the graphite has good dispersion stability. The prepared primer is an effective anti-corrosive primer, and can be widely applied to the field of metal corrosion prevention.

Description

technical field [0001] The invention relates to the technical field of environmental protection paint, in particular to an environmental protection metal primer. Background technique [0002] In addition to the basic performance of the primer, the antirust primer can also protect the metal from natural medium corrosion. Traditional antirust primers contain a large amount of heavy metals such as lead and hexavalent chromium, which are not suitable for the human body and the environment, so their use is limited. Therefore, it is necessary to prepare environmentally friendly and effective antirust primers. [0003] Graphite is crystalline carbon of the hexagonal system, chemically inert, has good electrical and thermal conductivity, high corrosion resistance and thermal stability, and is widely used in refractory materials, ceramics, coatings and other industries. Therefore, the metal primer prepared with graphite should have good acid, alkali, chemical and solvent corrosion ...
