Abstract

An electrostatic-conducted epoxy-resin terrace coating and its coating process are disclosed. The coating consists of finish and primer, finish uses conductive short-staple slurry with excellent conductive and dispersing performances, and surface and volume resistances reach to 5*10(4)-1*10(6)omega, furthermore, finish utilizes composite accessory system with disperser, leveling agent, antifoaming agent and rheological agent; primer uses conductive graphite powder, and surface and volume resistances reach to 10(3)-10(4)omega. The process is carried out by pasting conductive copper foil at an interval 1m*2m, building an electrostatic dissipative leakage layer, connecting a grounding device by1000m2 with grounding resistance<4omega and composing complete electrostatic leakage system. It's simple, convenient and has excellent and long-acting electrostatic-conducting effect.

Description

1. Technical field: [0001] The invention relates to materials for building floors, in particular discloses a conductive epoxy resin floor coating, which includes a topcoat, a primer and a coating process thereof, and belongs to the coating category in the chemical category. 2. Background technology: [0002] Anti-static floor coating is a kind of functional coating, which can endow the floor with conductivity to eliminate the large amount of static charge accumulated due to friction, and avoid static electricity from affecting production and causing fire, explosion and other accidents. According to the industry standard SJ / T11294-2003 "General Specification for Anti-static Floor Coatings" of the Ministry of Information Industry, anti-static floor coatings are divided into topcoats and primers, and topcoats are divided into self-leveling anti-static floor coatings, ordinary Anti-static floor coatings and elastic anti-static floor coatings, anti-static floor coatings are divid...
