Description

technical field [0001] The invention relates to the technology in the field of light-cured coatings, in particular to an antifouling, antistatic, high wear-resistant transparent light-cured coating and a preparation method thereof. Background technique [0002] Due to the characteristics of light and easy processing and excellent mechanical properties, polymer materials are increasingly used in various industrial production fields such as construction, machinery, packaging, electronics and medical treatment instead of metal and glass. Paint protection is almost a necessary process. However, whether it is a polymer material itself or an organic coating, the chemical bonds in the macromolecules are covalent bonds, which are not easy to ionize and transfer electrons. Therefore, when they rub against each other or contact and separate, they will easily generate high-voltage static electricity, causing electric shock or even discharge. Sparks can cause serious accidents. [000...

Problems solved by technology

[0004] At present, light-cured antistatic coatings generally improve the antistatic performance of the coating by adding quaternary ammonium salt antistatic agents, ionic liquids, metal powders or metal oxides, conductive polymers and other materials, of which the quaternary ammonium salt antistatic agents themselves It is not conductive, and it achieves the purpose of releasing static electricity through the principle of surface active water absorption or lubrication. It is very sensitive to the temperature and humidity of the environment, the effect is unstable and the surface migration is serious, the durability is poor, and it is easy to reduce the water contact angle of the coating. (Anti-fouling coatings generally require water contact greater than 108°), which weakens the anti-fouling properties of the coating; a large amount of metal powder or metal oxide needs to be added, which greatly affects the transparency of the coating; conductive polymers are currently an emerging technology , but most of the common conductive polymers such as polyaniline and polythiophene are water-based, which are difficult to disperse in the UV system, and the coating will have color. If the dispersion is not good, it will easily lead to local conductive properties that are too good to cause damage to electronic components;

[0005] Ionic liquids refer to salts that are liquid at or near room temperature and are composed entirely of anions and cations, also known as low-temperature molten salts, which are increasingly used because of their ionic conductivity, optical transparency, and thermal stability. In the field of film materials and coatings; but the current light-curing antistatic coatings cannot improve the compatibility of ionic liquids in light-curing high-wear antifouling coatings to improve their antistatic performance without reducing the coating.
