Abstract
The present invention provides a kind of fluororesin with photoinitiator group and its preparation and application.Photoinitiator group is in the side chain of fluororesin in fluororesin with photoinitiator group, and preparation method is synthesized by the fluororesin containing hydroxyl and the photoinitiator esterification containing carboxyl.The present invention also provides a kind of Photocurable compositions, by 0.1%~5% fluororesin with photoinitiator group, 87~98.9% reaction resin or activated monomer and 1~8% photoinitiator composition.The photo-curing paint of waterproof and oilproof soil resistance is significantly improved the present invention provides a kind of.
Description
Technical field:
The present invention relates to a kind of functional fluororesins, especially with the fluororesin and preparation method thereof of photoinitiator group
With application.
Background technique:
In paint field, weatherability is one of the important performance of outdoor coating, industrial at present main by directly adding
The method of fluorine material is modified coating, in coating add fluorine material can effectively improve coating waterproof and oilproof it is antifouling
Property, weatherability and chemical corrosion resistance.F-C paint is one of the kind of best performance show in the prior art.
Since fluorine material has the performances such as excellent thermal stability, corrosion resistance, low surface tension, answered extensively
With.In Chinese patent CN103059316A, fluorine-containing modified polyurethane is introduced into photocureable coating, for enhancing the resistance to of coating
Water anti-pollution characteristic；And in Chinese patent CN103589320A, fluorine-containing acrylate is added in pcb board three-proofing coating and participates in altogether
Poly-, to reduce the surface energy of film surface, but these schemes also bring the decline of film Yu substrate adhesive force, so that it is durable to influence its
Property.
Most common F-C paint is all the isocyanates and hydroxyl fluororesin catalytic crosslinking of two-component, needs high-temperature process item
Part, production efficiency is low, is unfavorable for outdoor site operation.
Light lnduced Free Radicals polymerization is also known as photocuring technology and is existed with its rapid curing, low pollution and the advantages such as energy-efficient
It is taken seriously both at home and abroad, is widely used in metal, timber, plastic coating, ink printing, textile printing, fibre coating etc.,
It is one of the cutting edge technology in coating, ink area.But photocuring technology is mainly drawn using acrylate and monomer and light
Agent composition is sent out, the cured film that they are formed does not have ideal waterproof, antifouling, weatherability also.
It is one of the method for improving photocureable coating performance that fluorine material, which is introduced into photocuring technology,.
Fluoride is introduced into initiator, the fluorine-containing photoinitiator as described in Chinese patent CN101812143A, it will
Photoinitiator is connected with small molecule perfluoro alkane synthesizes fluorine-containing photoinitiator.N- ethylperfluoro octyl sulphonyl is used in embodiment
The fluorine richness light that amine ethyl alcohol and UVINUL MS 40-carboxylic acid are reacted to obtain the small-molecular-weight for containing only an initiator group draws
Agent is sent out, and using the surface migration of fluorine material, causes gradient polymeric.And small molecule compound moves to surface and can both damage
The performance of film can also pollute the contactant of film, the toxicity of all-fluoroalkyl compound be exactly it is very troubling, as
Persistence organic pollutant has been put into the short-list of Convention of Stockholm (Shi Yali etc. the, " environment of perfluorochemical
Problem ", chemical progress, 2009,21 (3), 369).
The paper (Li Wei, Zou Yingquan, information-recording material, 2011,12 (5), 38) of Zou Yingquan summarize fluorochemical monomer or
