Problems solved by technology

Ordinary concrete floors do not have the effect of anti-static and non-flammable, and are prone to sparks when encountering impact or friction, which can easily cause fire or safety hazards in flammable and explosive environments
At present, the anti-static and non-flammable ground materials on the market mainly include metal aggregate type and non-metallic aggregate type. The metal aggregate type is complex in process, high in cost, and has heavy metal pollution; Dosage form, low strength, generally hard and brittle, poor impact resistance, high water-cement ratio, poor compactness, poor impermeability, unstable antistatic performance

Abstract

The invention provides an anti-static non-flammable ground material. The material is based on dolomite and cement, and modified metal conductive pearl powder is added. The metal conductive pearl powder is well compatible with dolomite and cement, and then added The water reducing agent improves the slump retention performance of the ground, and the anti-alkali agent is added to prevent the efflorescence of the ground. The anti-static non-flammable floor material provided by the invention has the properties of non-flammable, non-deflagration, wear-resistant, acid and alkali resistance, and the surface resistance value is 10 5 -10 8 Ω, excellent electrical conductivity, and increases the richness of the color of the ground material, which is rich in color and elegant in appearance. The preparation method of the antistatic non-flammable ground material provided by the invention is simple, the construction method is convenient and easy to operate, the antistatic non-flammable ground material can form a uniform conductive layer on the ground, the conductive performance is long-lasting and efficient, acid and alkali resistant, impact resistant, and not empty Drum, wear-resistant and pressure-resistant.

Description

technical field [0001] The invention belongs to the technical field of floor materials, and in particular relates to an antistatic non-flammable floor material and a preparation method thereof. Background technique [0002] With the upgrading of my country's industrialization, some special industries have higher and higher demands for fireproof and antistatic floor materials. The anti-static floor and non-fire floor of the traditional technology can no longer meet the market demand. As a near-field natural hazard source, static electricity has brought great losses and harm to human society. In special fields, such as military industry, electronics industry, and petrochemical industry, many serious accidents have occurred at home and abroad due to electrostatic discharge. Great losses have been caused to the national economy and personal life. Floor is a general term for various floors, and refers to a type of product that finally makes the floor present a certain decorativ...
