preparation example Construction

[0083] A kind of preparation method of UV photocurable composition additive, is characterized in that comprising following preparation steps:

[0084] a) adding the crosslinking agent iii), catalyst and solvent A into a three-necked flask, fully stirring the above solution evenly, and heating to the reaction temperature;

[0085] b) adding a mixture of perfluoropolyether i) and solvent A to the three-necked flask under stirring to obtain a mixed solution;

[0086] c) reacting the mixed solution at the reaction temperature for 4-10 hours;

[0087] d) adding the mixture of monomer ii) and solvent B into the three-necked flask under stirring, and reacting at the reaction temperature for 10-15h;

[0088] e) After the reaction, the mixture was cooled to room temperature and diluted with solvent B to 20% solid content.

[0089] The catalyst in step a) is an organic tin, organic aluminum, organic antimony compound, preferably an organic tin compound, more preferably dibutyltin dila...

Abstract

The invention discloses a UV photo-curing composition additive and a preparation method thereof. Raw materials for the additive include perfluorinated polyether containing polyether polyol groups, a monomer containing activated hydrogen groups and self-crosslinking functional groups and a non-fluorinated crosslinking agent, and the additive is prepared through reaction under a certain conditions. The additive is excellent in preservation stability before curing and can provide excellent waterproof, oil-proof, anti-fouling, anti-fingerprint and friction-resisting performance for a coating after curing. The UV photo-curing composition additive is mainly used for the coating having the waterproof, oil-proof, anti-fouling, anti-fingerprint and friction-resisting performance.

Description

technical field [0001] The invention relates to the technical field of special polymer materials in chemical synthesis, in particular to an additive for UV photocurable composition and a preparation method thereof. Background technique [0002] The UV light-curing composition uses ultraviolet light as the energy source for coating curing, without heating, and can quickly cure and form a film on substrates such as paper, plastic, leather and wood. The advantages of light-curing coatings are short curing time (a fraction of a second to a few minutes), low curing temperature, and low volatile matter. It is a new type of coating that saves energy, resources, pollution, and high efficiency. However, when the commonly used light-curing coatings are used on the surfaces of optical films, optical discs, electronic equipment exteriors, optical lenses (plexiglass), etc., there are shortcomings such as waterproof, oil-proof, anti-fouling, anti-fingerprint, and poor friction resistance....
