Embodiment 1

[0028] The preparation method of the first component of the floor primer coating:

[0029] Add 250g of waterborne epoxy resin curing agent II, 500g of water, and EFKA40506g to the dispersion kettle, disperse at 800rmp for 10 minutes, add 250g of conductive graphite, disperse at 3000rmp for 20 minutes, grind to The fineness is 30-50 μm, and it can be packaged after being filtered by a 200-mesh filter to obtain the first component of the water-based epoxy resin anti-static floor bottom and middle coating.

[0030] 150 g of bisphenol A epoxy resin with an epoxy equivalent of 185 and 17 g of o-phenyl glycidyl ether were stirred uniformly to form the B component.

[0031] When used as a primer, this component A and component B are mixed evenly, and evenly painted on the treated base surface.

[0032] When used as a middle coat, mix this component A and component B evenly, add an appropriate amount of quartz sand or quartz powder or talc powder or other volume pigments, mix well, a...

Abstract

The invention discloses water-based epoxy antistatic floor primer and surface paint and a preparation method thereof. The paint is composed of a component A and a component B, wherein the component A is composed of generation II water-based epoxy resin curing agent, water, conductive graphite and dispersing agent; and the component B is composed of bisphenol A epoxy resin and diluter. The preparation method comprises the following steps: dispersing the conductive graphite in a water solution of the generation II water-based epoxy resin curing agent through the dispersing agent, and grinding to obtain the component A; and adding the corresponding component B to obtain the paint. The paint is environment-friendly, favorable in safety and good in antistatic property; and the preparation method is simple, quick and low in cost, and can realize industrial production.

Description

technical field [0001] The invention relates to a water-based epoxy antistatic floor bottom, middle coating and a preparation method thereof, belonging to the technical field of coatings. Background technique [0002] The generation and accumulation of static electricity will bring many troubles and even disasters to modern life, production and scientific activities. In the fields of electronics, communications and other fields, the accumulation of a large amount of static electricity can easily cause interference to electronics, communications or computers, and affect the performance of the equipment; in the chemical field, the discharge caused by the accumulation of static electricity can even cause safety accidents such as fire and explosion. Therefore, epoxy floor coatings that can discharge accumulated static charges and have anti-static properties are used as needed and are accepted in more and more occasions. [0003] Epoxy resin is the most used synthetic material i...
