Abstract

The invention discloses an epoxy self-leveling antistatic topcoat and a preparation method thereof, and relates to the technical field of epoxy floor coatings. The problem that a coating film easily generates micro-cracks due to frequent friction or impact is solved and an accident caused by micro-cracks is prevented. The epoxy self-leveling antistatic topcoat comprises a component A and a component B, the component A and the component B are independently stored and mixed according to the weight part ratio of (4-6): 1, the component A comprises the following raw materials in parts by weight: 25-35 parts of bisphenol A type epoxy resin; 1.1 to 1.5 parts of an active diluent AGE; 1.4 to 1.8 parts of benzyl alcohol; 0.8 to 1.2 parts of a Disponer 9250 wetting and dispersing agent; 0.3 to 0.5part of a defoaming agent; 0.5 to 0.9 part of a leveling agent; 0.6 to 1.2 parts of wax powder; 0.6 to 0.9 part of an anti-settling agent; 40 to 50 parts of silicon barium powder; 8 to 16 parts of epoxy color paste; 4 to 10 parts of electro-conductive graphene; 2.5 to 5.5 parts of an electro-conductive auxiliary agent; and 4-6 parts of toughened modified wiredrawn proteins; and the component B isa polyether amine curing agent. The provided epoxy self-leveling antistatic topcoat can maintain a good and stable antistatic performance.

Description

technical field [0001] The invention relates to the technical field of epoxy floor coatings, in particular to an epoxy self-leveling antistatic surface coating and a preparation method thereof. Background technique [0002] Epoxy floor coatings have been used for functional floors from the beginning: such as anti-corrosion, wear-resistant, anti-skid, and developed to general industrial floors; in addition to functional requirements, they also have decorative effects. At the same time, the film-forming substances of epoxy resin floor coatings are mainly composed of epoxy resin and epoxy resin curing agent. [0003] A kind of antistatic floor paint and preparation method thereof are disclosed in the Chinese invention patent application document whose publication number is CN108300129A, wherein, the antistatic floor paint comprises A component and B component, and described A component is made up of following weight The number of raw materials prepared: 30-40 parts of water-ba...
