Abstract
The present invention provides a kind of dual cure UV varnish, and matrix resin includes following components: 6 official's hydroxyl alkyd resins, 4 official's hydroxyl alkyd resins, 4 official's polyurethane resins.Dual cure UV varnish of the present invention is suitable for irregular plastic parts；The position that can be mapped to by ultraviolet lighting on plastic parts, the UV varnish on these positions can be solidified by ultraviolet light cross-linking；Ultraviolet light can not irradiate or irradiate insufficient position on plastic parts, and the UV varnish on these positions can also carry out secondary supplement crosslinking curing using isocyanates under the conditions of room temperature or 50~70 DEG C of temperature.
Description
Technical field
The present invention relates to dual cure UV varnish.
Background technique
For irregular plastic parts, such as use one-component UV system, because of the irregular surface of plastic parts, ultraviolet light without
Method irradiates or irradiates insufficient position, ultraviolet light solidification crosslinking can not be carried out, to influence product quality.So current row
The spraying of PU system is all made of to irregular plastic parts in industry, and the system needs to consume excessive energy during cured
Consumption, also creates a large amount of pernicious gas, inefficiency, at the same the aspect of performance such as scratch-resistant, wear-resisting, hardness have it is congenital not
Foot.
Summary of the invention
The purpose of the present invention is to provide a kind of dual cure UV varnish, and it is suitable for irregular plastic parts；Plastic parts
On the position that can be mapped to by ultraviolet lighting, the UV varnish on these positions can solidify by ultraviolet light cross-linking；It is purple on plastic parts
Outer light can not irradiate or irradiate insufficient position, and the UV varnish on these positions can also be in room temperature or 50~70 DEG C of temperature
Secondary supplement crosslinking curing is carried out using isocyanates under the conditions of degree.
To achieve the above object, the present invention provides a kind of dual cure UV varnish, and matrix resin includes following components:
6 official's hydroxyl alkyd resins,
4 official's hydroxyl alkyd resins,
4 official's polyurethane resins.
Preferably, in the matrix resin:
The mass percentage of 6 official's hydroxyl alkyd resins is 15%,
The mass percentage of 4 official's hydroxyl alkyd resins is 10%,
The mass percentage of 4 official's polyurethane resins is 10%.
Preferably, the dual cure UV varnish, also contains initiator aid.
Preferably, the dual cure UV varnish, also contains auxiliary agent.
Advantages and advantages of the present invention are to provide a kind of dual cure UV varnish, it is suitable for irregular modelings
Glue part；The position that can be mapped to by ultraviolet lighting on plastic parts, the UV varnish on these positions can be solidified by ultraviolet light cross-linking；
Ultraviolet light can not irradiate or irradiate insufficient position on plastic parts, and the UV varnish on these positions can also be in room temperature or 50
Secondary supplement crosslinking curing is carried out using isocyanates under the conditions of~70 DEG C of temperature.
The hydroxyl group of functional group's resin insertion, being capable of insufficient to light source irradiation under the action of isocyanates or photograph
Penetrate less than position carry out secondary cross-linking solidification, to reach completion of cure, the uniform paint film of forming properties.
The curing mode of dual cure UV varnish of the present invention has two kinds: 1) by absorbing ultraviolet light solidification；And isocyanic acid 2)
Ester carries out chemical crosslinking cure in room temperature or 50~70 DEG C of temperature condition.
The present invention has diversified curing mode, and irregular plastic rubber member surface spraying UV paint can be allowed to be achieved,
Some ultraviolet source irradiations less than or the insufficient place of irradiation, can be by carrying out secondary supplement friendship with isocyanates
Connection solidification, with the paint film being had excellent performance.
The distinctive dual cure mode of dual cure UV varnish of the present invention can replace PU paint to be used for irregular workpiece table
Face coating.Compared to PU paint, the present invention production efficiency, performance, in terms of be all greatly improved.
Dual cure UV varnish of the present invention replaces PU system to be used for the spraying of irregular plastic parts, and production efficiency can be improved,
Energy consumption is reduced, while because it is large arch dam product, the discharge of exhaust gas is greatly reduced during chemical crosslinking, is alleviated to ring
The pollution in border.In addition, dual cure UV varnish of the present invention is in aspect of performance, especially scratch-resistant, wear-resisting, the performances such as hardness have
Very big raising.
Specific embodiment
With reference to embodiment, the specific embodiment of the present invention is further described.Following embodiment is only used for more
Add and clearly demonstrate technical solution of the present invention, and not intended to limit the protection scope of the present invention.
The technical solution that the present invention embodies is:
The present invention provides a kind of dual cure UV varnish, and matrix resin includes following components:
6 official's hydroxyl alkyd resins,
4 official's hydroxyl alkyd resins,
4 official's polyurethane resins.
Preferably, in the matrix resin:
The mass percentage of 6 official's hydroxyl alkyd resins is 15%,
The mass percentage of 4 official's hydroxyl alkyd resins is 10%,
The mass percentage of 4 official's polyurethane resins is 10%.
Preferably, the dual cure UV varnish, also contains initiator aid.
Preferably, the dual cure UV varnish, also contains auxiliary agent.
Dual cure UV varnish of the present invention, it is suitable for irregular plastic parts；It can be mapped to by ultraviolet lighting on plastic parts
Position, the UV varnish on these positions can solidify by ultraviolet light cross-linking；Ultraviolet light can not be irradiated or be irradiated on plastic parts
Insufficient position, the UV varnish on these positions can also utilize isocyanic acid under the conditions of room temperature or 50~70 DEG C of temperature
Ester carries out secondary supplement crosslinking curing.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvements and modifications can also be made, these improvements and modifications
Also it should be regarded as protection scope of the present invention.
