Abstract

The invention belongs to the technical field of anti-corrosive paint, provides a super thick film solvent-free hot spray fast dried heavy-duty coating and a preparation method thereof. The component A of the heavy-duty coating comprises 20.0-35.0 of epoxide resin, 3.0-5.0 of reactive diluent, 2.0-5.0 of plasticizer, 0.5-1.5 of foam killer, 1.5-3.0 of thixotropic agent, 0.5-2.0 of wetting dispersant, 20.0-30.0 of inhibitive pigment, 20.0-30.0 of cracking prevention stuffing, and 7.0-18.0 of homemade thixotropy slurry; the component B thereof comprises 40.0-55.0 of firming agent I, 2.0-2.5 of curing accelerator, 2.0-3.0 of thixotropic agent, and 40.0-50.0 of wear resistance pigment. The paint film of the heavy-duty coating has good stopping property, excellent performances of adhesive attraction, high hardness, good wearing resistance, fast surface drying, short hardening time and the like. The heavy-duty coating is suitable for being coated in multiple conditions, can be coated in a streamlined way in the special production line, also can be applicable to minor works, small amount coating; the thickness of the first film forming can reach 1000 mum.

Description

technical field [0001] The invention belongs to the technical field of anti-corrosion coatings, and in particular relates to an ultra-thick film solvent-free thermal spraying quick-drying heavy-duty anti-corrosion coating and a preparation method thereof. Background technique [0002] At present, there are many epoxy heavy-duty anti-corrosion coatings in the known technology, which are widely used in heavy-duty anti-corrosion fields such as industrial pipelines and ports and wharfs, and have excellent performance. In addition, the industry continues to introduce new ones, and the new technology level develops rapidly. [0003] The Chinese patent application whose patent application number is 200710054013.7 discloses a heavy-duty anti-corrosion coating for marine steel structures. The coating is widely used in heavy anti-corrosion fields such as seaports and wharfs due to its excellent anti-corrosion performance. However, due to its high viscosity, it can only be applied by s...
