Problems solved by technology

[0002] The epoxy resin in the existing solvent-free epoxy anti-corrosion paint is mostly bisphenol A epoxy resin. In practical applications, in order to reduce the viscosity of general bisphenol A epoxy resin, reactive diluents are often added to the system Improve its process performance, but the reactive diluent reduces the mechanical and thermal properties of the anti-corrosion paint to a certain extent, so we recommend starting from the epoxy resin itself, reducing or even not adding reactive diluents

Abstract

The invention discloses solvent-less epoxy anti-corrosive paint. The solvent-less epoxy anti-corrosive paint is prepared from a component A and a component B in mass ratio of 100:18, wherein the component A comprises epoxy resin, auxiliary agents and a filler, and the component B is an amine curing agent; the epoxy resin is a mixture of bisphenol F type epoxy resin and bisphenol A type epoxy resin, and the mass ratio of the bisphenol F type epoxy resin to the bisphenol A type epoxy resin is (30-50):100; and the auxiliary agents comprise a leveling agent, a defoaming agent, a wetting dispersant and a coupling agent, the filler is mica powder, and the amine curing agent is a cardanol modified amine curing agent. In the technical scheme, the bisphenol F type epoxy resin and the bisphenol A type epoxy resin are mixed for preparing the epoxy resin, physical blending modification is carried out, so the viscosity of the bisphenol A type epoxy resin is obviously reduced, a reactive diluent needs not to be added, and the mechanical property and hot property are superior.

Description

technical field [0001] The invention relates to an anticorrosion paint, in particular to a solvent-free epoxy anticorrosion paint. Background technique [0002] The epoxy resin in the existing solvent-free epoxy anti-corrosion paint is mostly bisphenol A epoxy resin. In practical applications, in order to reduce the viscosity of general bisphenol A epoxy resin, reactive diluents are often added to the system Improve its process performance, but the reactive diluent reduces the mechanical and thermal properties of the anti-corrosion paint to a certain extent, so we recommend starting from the epoxy resin itself, reducing or even not adding reactive diluents. Contents of the invention [0003] In view of the above problems, the object of the present invention provides a solvent-free epoxy anticorrosion paint, in which bisphenol F type epoxy resin and bisphenol A type epoxy resin are mixed to obtain epoxy resin, and physical blending is carried out Modification, significantl...
