Solvent-free phenolic epoxy electrostatic conductive coating formula and preparation method thereof

Abstract

The invention discloses a solvent-free phenolic epoxy electrostatic conductive coating formula. The coating is prepared from a component A and a component B with the weight ratio being (8-12) to 1, wherein the component A is prepared from the following components in percentage by weight: 15-25 percent of phenolic epoxy resin, 5-15 percent of flexible epoxy resin, 5-10 percent of a reactive diluent, 15-25 percent of conductive mica powder, 5-12 percent of a salt fog resistance additive, 12-20 percent of a pigment, 2-5 percent of a nanometer hardening agent, 1-2 percent of a dispersant, 0.1-0.5 percent of a defoamer, 0.3-0.8 percent of a flatting agent, 0.5-1.5 percent of a rheological additive and 0.5-2.0 percent of a silane coupling agent; and the component B is an epoxy curing agent. The invention also discloses a preparation method of the solvent-free phenolic epoxy electrostatic conductive coating. By adopting a paint film surface waterborne transition paint obtained by the invention, through high-pressure airless spraying, a paint film can have heat resistance and wear resistance, has the surface resistance / volume resistance being smaller than 1*10<6> and meets the requirements of an oil storage tank and a pipeline for electrostatic conduction after being dried.

Description

technical field [0001] The invention relates to a static conductive paint, in particular to a formula of a solvent-free phenolic epoxy conductive paint and a preparation method thereof. Background technique [0002] Static conductive coating is a functional coating that eliminates static accumulation and conducts current, and is divided into intrinsic type and additive type. The additive type has the advantages of easy production, easy construction, good performance, and high cost performance, and has been widely used in petrochemical, transportation and other fields; in the actual application process, some electrostatic conductive coatings are solvent-based coatings, which have occupational health and safety problems. Solvent-free epoxy electrostatic conductive coatings have problems such as low cost performance, poor anti-corrosion performance, non-temperature resistance, and non-wear resistance. Contents of the invention [0003] In order to overcome the technical defe...
