Embodiment Construction

[0050] A method for preparing an epoxy primer for electrostatic spraying of rail transit bogies, comprising two parts, a paint material and a curing agent, characterized in that the epoxy primer is made of the following raw materials and steps:

[0051] (1) The weight ratio of the raw materials that make up the paint is:

[0052] Composite antirust material 25-32 parts Bisphenol A epoxy resin: 8-12 parts

[0053] Novolac epoxy resin 20-25 parts Silicone leveling agent 1-2 parts

[0054] Anti-corrosion corrosion inhibitor 0.2-0.5 parts Polyamide wax anti-settling agent 1-3 parts

[0055] Dispersant 2-3 parts Substrate wetting agent 1-2 parts

[0056] Silicone defoamer 0.5-1 functional material slurry 5-8 parts

[0057] Pigment 10-14 parts Thinner 10-15 parts

[0058] The composite antirust material is mica powder: barium sulfate: talcum powder: zinc oxide: aluminum tripolyphosphate=1:4:4:2:2;

[0059] Diluent is diacetone alcohol: 100# solvent: 150# solvent=1:1:1 mixed sol...

Abstract

The invention relates to an epoxy primer for electrostatic spraying of a rail traffic bogie, and a preparation method thereof. Epoxy resin, a composite antirust material, a coloring pigment, a functional material slurry, an assistant and a solvent form a paint; low-molecular polyamide, alicyclic amine, an assistant and a solvent form a curing agent; and the primer is prepared from the paint and the curing agent according to a weight ratio of 100:20 when constructed, and a proper amount of a diluent is added to adjust the construction viscosity in order to facilitate construction. The epoxy primer can adapt to mixed gas electrostatic spray gun spraying and electrostatic adsorption, and has the advantages of good environmental protection effect, small paint mist spray, high painting rate, good conductivity in a dry film, no influences on the electrostatic spraying, and realization of a coating layer with the performances meeting technical requirements of the primer for rail traffic bogie, and the epoxy primer can reduce the use amount of a paint by 30% or more when used in the mixed gas spray gun electrostatic spraying construction of the rail traffic bogie in order to reduce paint mist and the emission of VOCs, so the epoxy primer is an environmentally-friendly coating.

Description

technical field [0001] The invention relates to a paint with excellent enveloping effect and extremely high paint utilization rate when using an air-mixed spray gun for electrostatic spraying, in particular to an epoxy primer for electrostatic spraying of rail transit bogies and a preparation method thereof. Background technique [0002] In recent years, the overall development trend of the rail transit industry has been good, especially the subways and light rails in various cities have received great attention and support. The number of standard urban rail transit vehicles in operation in the country has risen from 34,415 units in 2013 to 2015 by the end of 2015. 48,165 units, and the number has continued to grow at a rate of more than 7,000 units per year in the past two years. With the increase in the number of rail transit vehicles, all spraying construction units are actively improving the spraying method to improve production efficiency. The primers for urban rail tr...
