Problems solved by technology

But so far, neither of these two companies has applied intrinsic polyaniline and conductive polyaniline to the manufacture of metal anti-corrosion water-based coatings, because the first intrinsic polyaniline and conductive polyaniline were only produced in 2006 The second is that if they are used to manufacture water-based metal anti-corrosion coatings, they will face the technical problem of solving their water solubility and dispersion (conductive polyaniline is generally dispersible in solvents such as xylene and butanol)

Embodiment 1

[0036] Embodiment 1 is to manufacture a water-based primer, so the salt spray resistance time detected in neutral salt spray is routinely carried out for 1000 hours.

Embodiment 2

[0037] Embodiment 2 is to manufacture water-based topcoat, which is different from the conventional 500-hour salt-spray resistance of solvent-based paint, and its salt-spray resistance test time is 740 hours.

[0038] Embodiment 1: prepare with the weight percent of all components:

[0039] ① Base material components: 500 mesh zinc powder 50%, coating film-forming water-based epoxy resin 14%, intrinsic polyaniline 1.5%, deionized purified water 18.9%, thickener 2%, dispersing anti-sedimentation agent 3% , 2% defoamer, 3% leveling agent.

[0040] ② Curing agent component: amine-based curing agent 5.6%.

Abstract

The invention relates to an industrial coating which uses polymer synthesis material of Eigenstae polyaniline and conducting state polyaniline so as to be respectively used for preparing industrial coating which can be matched as series of metal antisepsis waterborne basecoat and surface coating. As solvent is not used, the prepared metal antisepsis waterborne basecoat and the surface coating are non-solvent typed metal antisepsis industrial coatings which have extremely low VOC content and are friendly to the environment and used for the metal substrate surface. Being different from the cathode protection function of normally used sacrifice-typed antisepsis coating on the metal surface, the eigenstae polyaniline metal antisepsis waterborne industrial coating is an anode protective coating used for the metal material.

Description

technical field [0001] The invention relates to the use of intrinsic state polyaniline (Eigenstate Polyaniline) and conductive state polyaniline (Conducting State Polyaniline) to manufacture industrial coatings for metal anti-corrosion water-based primers and top coatings that can be matched into a system. Since no organic solvent is used, the metal anti-corrosion water-based primer and top coat are very low VOC (organic volatile) content and environmentally friendly non-solvent metal anti-corrosion industrial coatings for metal substrates. Unlike the commonly used sacrificial anti-corrosion coatings for cathodic protection of metal surfaces, polyaniline metal anti-corrosion water-based industrial coatings are a type of anodic protection coatings for metal materials. Background technique [0002] Corrosion of metals is ubiquitous, and it is mainly concentrated on the most used steel materials. It is the most important factor causing the natural loss of various facilities and...
