Description

Technical Field

[0001] The invention relates to the technical field of coating materials, and in particular to an antistatic composition and a preparation method and application thereof, a non-ignitable antistatic putty powder and a putty slurry. Background Art

[0002] With the development of society, the demand for materials in various fields has shown a trend of diversification and specialization. Some special places such as military manufacturing, fireworks manufacturing, pharmaceutical factories, wineries, gas stations, chemical plants, precision electronics factories, textile factories, printing factories, sterile medical laboratories and other flammable and explosive places have special fire protection and explosion prevention requirements. In order to ensure safe production and safe operation, the fire protection and anti-static requirements for the floor and wall and other related environmental materials in such special places are very strict, and they must have certain non-flammable and anti-static properties. The so-called non-flammable property is the conversion of kinetic energy. "When the material is subjected to mechanical effects such as friction, impact or rubbing with hard objects such as metal or stone, sparks or sparks will not occur, causing the danger of flammable materials causing fire or explosion." The reason for the ignition of wall and floor materials is generally due to the accumulation of static electricity caused by mechanical impact and friction. When the external conditions are suitable, there will be hidden dangers of fire or explosion. Therefore, wall and floor materials with special fire protection requirements must have the functions of non-flammable and anti-static. With the directional focus of demand, researchers from scientific research institutions and universities around the world continue to expand their research on non-flammable materials.

[0003] At present, the research on non-flammable materials is focused on floor materials. According to the properties of the materials, they can be divided into non-flammable metal floors and non-flammable non-metal floors. Non-flammable metal floor materials are generally made of non-ferrous metals such as copper plates and aluminum plates. Non-flammable non-metal materials can be divided into non-flammable organic floor materials, such as asphalt, wood, rubber, etc., but because these materials have poor conductivity and certain insulation, they are not conducive to static electricity conduction, and it is necessary to set up electrical conduction; the other is non-flammable inorganic floor materials, which are made of inorganic materials such as concrete and terrazzo configured with non-flammable sand and gravel aggregates.

[0004] CN104211345A discloses a non-fired concrete prepared with common sand, which is prepared by mixing cementitious material cement, common sand, non-fired coarse aggregate, water, and admixtures in proportion. The cementitious material cement adopts common cement with a strength grade of 32.5 or slag cement with a strength grade of 32.5; the non-fired coarse aggregate adopts dolomite or limestone with a particle size of 10 to 20 mm; the common sand adopts fine sand with a fineness modulus of 1.6 to 2.1; the admixture is selected from one or more of a water reducer, a retarder, a plasticizer, and a composite soil adsorbent. This scheme provides a way of thinking that common sand is combined with non-fired aggregate to achieve non-fire and does not affect the material properties and mechanical properties of concrete, but there are certain requirements for the ratio of common sand to non-fired aggregate, and at this stage, with the tightening of relevant environmental protection policies, the price of common sand and non-fired machine-made sand aggregate are inverted, and the economy is no longer advantageous.

[0005] CN116903319A discloses an anti-static non-flammable wear-resistant floor material and a preparation method thereof, wherein the floor material comprises component A and component B in a mass ratio of (4-7):1, wherein component A comprises 30-45% cement, 45-55% non-flammable aggregate, 1-3% active admixture, 5-10% functional admixture, 0.5-1% special admixture and 0.1-1.2% conductive material by mass fraction, and component B is a polymer emulsion. The core of this scheme is to utilize the cross-linking of two-component materials to enhance the rigidity and flexibility of the material, and at the same time, composite conductive materials and non-flammable aggregates to achieve non-flammable and anti-static effects. This scheme increases the construction process and construction difficulty compared to single-component materials, and in actual construction, workers are very likely to add less or omit one of the components in order to save time, which increases many quality risks.

[0006] In view of this, the present invention is proposed. Summary of the invention
