[0040] Correspondingly, the embodiment of the present invention provides a method for preparing an environmentally friendly anticorrosive coating, including the following steps:

[0041] S01. Weigh each component according to the above-mentioned environmental protection anticorrosive coating formula;

[0042] S02. Add the low-viscosity solvent-free epoxy resin into the mixing tank, and then add the diluent, toughening resin, toner, seasoning, low-viscosity epoxy ester resin, and thixotropic agent in sequence, and stir them separately to form a dispersion Main paint agent;

[0043] S03. Add the modified amine resin to the mixing tank and stir to form a curing agent;

[0044] S04. Mix the main agent and curing agent to form an environmentally friendly anticorrosive coating.

[0045] Specifically, in the above step S01, the formulation components and their contents of the environmentally friendly anticorrosive coating have been stated above, and in order to save space, they will not be re...

Embodiment 1

[0052] An environmentally-friendly anticorrosive coating, comprising a main agent and a curing agent, based on 100 parts by weight of the main agent, including each component in parts by weight as shown in Example 1 of Table 1.

[0053] The preparation method of the environmental protection anticorrosive coating includes the following steps:

[0054] S11. Weigh each component according to the above-mentioned environmental protection anticorrosive coating formula;

[0055] S12. Add the low-viscosity, solvent-free epoxy resin to the mixing tank, then add the diluent to the mixing tank, and stir evenly at low speed (50RPM) to form a uniform first mixture; toughen the The resin was added to the first mixture and stirred at low speed (50RPM) to form a uniform second mixture; the toner was added to the second mixture and stirred at low speed (50RPM) to form a uniform The third mixture; add the filler to the third mixture, and stir evenly at low speed (50RPM) to form a uniform fourth mixtu...

Abstract

The invention provides environment-friendly anticorrosive paint and a preparation method thereof. The environment-friendly anticorrosive paint comprises a main agent and a curing agent. The main agent is prepared from, by weight of 100 parts, 39-50 parts of low-viscosity solvent-free epoxy resin, 4-8 parts of diluents, 5-15 parts of toughening resin, 0.5-15 parts of toner, 10-40 parts of filler, 5-15 parts of low-viscosity epoxy ester resin and 0.5-1.5 parts of a thixotropic agent. The curing agent is modified amine resin.

Description

Technical field [0001] The invention belongs to the technical field of coatings, and particularly relates to an environmentally friendly anticorrosive coating and a preparation method thereof. Background technique [0002] Since heavy-duty anti-corrosion coatings can be applied in relatively harsh corrosive environments and have a longer protection period than conventional anti-corrosion coatings, heavy-duty anti-corrosion coatings are playing an increasingly important role in the construction of national economy and national defense, such as shipbuilding, machinery Heavy anti-corrosion coatings are inseparable from fields such as equipment manufacturing and national defense industry. In recent years, with the development of my country's defense industry, diversified anti-corrosion coatings will come out with the development of science and technology. [0003] In many anti-corrosion fields, such as the normal transportation of ships and the normal use of bridges, there are often s...
