Problems solved by technology

Metal-based fillers have the disadvantage of poor anti-oxidation performance, and ordinary metal-based oxide fillers have poor conductivity and cannot meet the needs of some occasions
The moisture-absorbing filler can gradually penetrate into the surface of the floor paint. Due to its moisture absorption, a thin layer of water film is formed on the surface of the floor paint, which has anti-static properties. However, due to the gradual wear and tear of the filler on the surface, its life is short ( 3 months to 1 year)

Embodiment 1

[0027] A kind of graphene antistatic additive for floor paint, proportioning is as follows:

[0028]

[0029] Concrete process route is: join weighed dispersant and anti-sedimentation agent in the solvent medium speed (1000 rev / min) stir and mix 30 minutes, then graphene conductive filler is added in the solvent gradually, constantly slow speed ( 500 rev / min) stirring to make the conductive filler infiltrate quickly. After the addition is completed, seal and mix rapidly (2000 rpm) for 1-3 hours at a low temperature of 10° C., and the prepared slurry can be used as an antistatic additive. The proportion of antistatic additives used is 4% of the floor paint. 4% addition ratio can achieve square resistance at 10 8 Ω-level anti-static effect, and can also effectively improve the wear-resistant, stain-resistant, waterproof, and anti-corrosion properties of the floor paint.

Embodiment 2

[0031] A kind of graphene antistatic additive for floor paint, proportioning is as follows:

[0032]

[0033] Concrete process route is: join weighed dispersant and anti-sedimentation agent in the solvent medium speed (1000 rev / min) stir and mix 30 minutes, then graphene conductive filler is added in the solvent gradually, constantly slow speed ( 500 rev / min) stirring to make the conductive filler infiltrate quickly. After the addition is completed, seal and mix rapidly (2000 rpm) for 1-3 hours at a low temperature of 10° C., and the prepared slurry can be used as an antistatic additive. The proportion of antistatic additives used is 6% of the floor paint. 6% addition ratio can achieve square resistance at 10 7 Ω-level anti-static effect, and can also effectively improve the wear-resistant, stain-resistant, waterproof, and anti-corrosion properties of the floor paint.

Embodiment 3

[0035] A kind of graphene antistatic additive for floor paint, proportioning is as follows:

[0036]

[0037] Concrete process route is: join weighed dispersant and anti-sedimentation agent in the solvent medium speed (1000 rev / min) stir and mix 30 minutes, then graphene conductive filler is added in the solvent gradually, constantly slow speed ( 500 rev / min) stirring to make the conductive filler infiltrate quickly. After the addition is completed, seal and mix rapidly (2000 rpm) for 1-3 hours at a low temperature of 10° C., and the prepared slurry can be used as an antistatic additive. The proportion of antistatic additives used is 8% of the floor paint. 8% addition ratio can achieve square resistance at 10 8 Ω-level anti-static effect, and can also effectively improve the wear-resistant, stain-resistant, waterproof, and anti-corrosion properties of the floor paint.

Abstract

The invention provides a graphene antistatic additive for floor paint. A specific technology comprises the following steps: adding weighed dispersant and anti-settling agent into a solvent and stirring and mixing at a middle speed for 30min; then gradually adding graphene conductive filler into the solvent; meanwhile, continuously stirring at a slow speed to rapidly wet the conductive filler; after adding, sealing and rapidly stirring and mixing for 1 to 3h under the low-temperature condition of 10 DEG C to prepare slurry which can be used as the antistatic additive. The utilization ratio of the antistatic additive is 4 to 8 percent of the floor paint. The antistatic additive can reach an antistatic effect less than or equal to 10<8>omega when the adding ratio is not higher than 10 percent; meanwhile, wear-resisting performance, dirt-resisting performance, waterproof performance, anti-corrosion performance and the like of the floor paint also can be effectively improved.

Description

technical field [0001] The invention belongs to the field of chemical coatings, and relates to a long-term and high-efficiency antistatic additive for floor paint and a preparation method thereof. Background technique [0002] Floor paint is a kind of decorative, anti-corrosion and wear-resistant coating. It has many characteristics such as bright and beautiful, wear-resistant and non-slip, waterproof and anti-corrosion. In the electronics and precision instrument industry, military industry, medicine and food hygiene industry, there are also units for the use, storage and production of flammable and explosive products. Because the floor is often subject to friction, it is easy to accumulate a large amount of electrostatic charge. On the one hand, the charge may cause permanent damage to precision electronics and instruments and cause them to fail. Great personal and property damage will result. Therefore, in the above-mentioned fields, it is necessary to modify the floor ...
