preparation example Construction

[0037] The preparation method of above-mentioned long-acting antistatic coating of the present invention comprises the steps:

[0038]The fluorosurfactant is firstly mixed and dispersed with the inorganic nano-conductive agent, and then mixed with the photosensitive resin, active monomer, photoinitiator, fluorosurfactant and diluent.

[0039] The invention provides an antistatic coating, and the material forming the antistatic coating includes the above-mentioned long-lasting antistatic coating.

[0040] The present invention also provides an antistatic product having the above-mentioned antistatic coating.

[0041] The antistatic coating is obtained by coating the above-mentioned long-lasting antistatic coating on the base material through a coating process, followed by drying and photocuring.

[0042] Further, the coating process can be spray coating, flow coating, dip coating, roller coating, brush coating and the like. The coating process is simple and easy to operate. ...

Abstract

The invention relates to long-acting anti-static coating and an anti-static coating. The long-acting antistatic coating comprises the following raw materials in parts by mass: 3-4 parts of photosensitive resin; 3-6 parts of an active monomer; 0.5 to 1 part of a photoinitiator; 0.001 to 0.3 part of an inorganic nanometer conductive agent; 0.1 to 0.5 part of a fluorine surfactant; and 60 to 120 parts of a diluent. According to the anti-static coating disclosed by the invention, under the condition that the addition amount of the inorganic nano conductive agent is relatively small, a good anti-static effect is ensured, and the light transmittance of an original base material is kept.

Description

technical field [0001] The invention relates to the technical field of material chemistry, in particular to a long-acting antistatic coating and an antistatic coating. Background technique [0002] As a functional coating, anti-static coating has been more and more used and developed along with the development of the microelectronics industry and the continuous improvement of production safety requirements. Different industries have different requirements for the resistance value and light transmittance of anti-static coatings. For example, floor coatings require a resistance value of 10 4 ~10 9 Ω, the steel oil tank requires a resistance value of 10 8 ~10 11 Ω, the above two fields do not require the light transmittance of the coating, while the anti-static coating of PVC / PC / PMMA boards often requires a resistance value of 10 6 ~10 8 Ω, and has high requirements for light transmittance (generally △T<2%), and is generally used in high-end mobile equipment protection ...
