Abstract
The invention discloses a UV varnish, which comprises the following parts: 25-45% monomer, 50-70% photographic resin, 4-7% photo-initiation agent, 0.7-1.7% adjuvant and 40-60% solvent, wherein the monomer consists of TMPTA and DPHA; the photographic resin is aliphatic PUA, which contains UV7605B and 621A-8; the photographic resin includes Irgacure184 and the adjuvant contains EFKA3777, EFKA3034 and OB (optical brightener); the solvent contains toluene and acetic ester. The invention matches high hardness resin and high hardness active diluent with OB to realize the uniformity of high hardness and low yellow changing rate, which reduces cost with good economic benefit.
Description
Technical field
The present invention relates to a kind of UV coating, particularly relate to a kind of UV varnish that is used for the application plastic bottom material.
Background technology
UV coating is to utilize uviolizing to produce chemical action and hardened coating, its main component is made up of photosensitive resin, reactive thinner, light trigger and auxiliary agent, this coating with high-octane UV-light as solidifying the energy, absorb ultraviolet luminous energy by the light trigger in the coating and form free radical, cause photosensitive resin and reactive thinner molecule, and then the generation chain polymerization, making films reaches curing.
UV coating has advantages such as curing speed is fast, energy-conservation, ambient cure, superior performance, environmental protection, ray velocity is fast on it, rete luminance brightness height, face firm surface heat-resisting, that can make ground in dry back is very bright, level and smooth, refractive power is effective, make ground produce the sense of intensive main body, be widely used in fields such as chemical industry, machinery, electronics, light industry, communication.Just because of these advantages make its application in recent years more and more widely, the high-tech high added value electronic product of fast development behind the UV Lacquer finish, looks that light is gorgeous beautiful more especially day by day, and therefore marketable value is also promoted greatly.
Plastic bottom material does not in the market have some obvious defects with UV varnish, and is high as: hardness, behind ultra violet lamp and the xanthochromia that causes etc.It is also big to become the high often caused xanthochromia of resin of connection density, makes UV varnish be difficult on high rigidity and the low-yellowing and unifies.
Summary of the invention
The object of the present invention is to provide a kind of UV varnish, the method that it adopts high hardness resin and high rigidity reactive thinner to arrange in pairs or groups is added white dyes OB simultaneously, to realize the system on high rigidity and the low-yellowing
For achieving the above object, UV varnish provided by the invention mainly comprises following component, and its content is expressed as with parts by weight:
Monomer 25～45
Photosensitive resin 50～70
Light trigger 4～7
Auxiliary agent 0.7～1.7
Solvent 40～60
Wherein, described monomer comprises TMPTA and DPHA etc.
Described photosensitive resin is aliphatics PUA, and it comprises UV7605B and 621A-80 etc.
Described light trigger comprises Irgacure184 etc.
Described auxiliary agent comprises EFKA3777, EFKA3034, white dyes OB etc.
Described solvent comprises toluene, ethyl acetate etc.
Therefore, the screening formulation of UV varnish of the present invention is expressed as with parts by weight:
TMPTA 10～20
DPHA 15～25
UV7605B 40～50
621A-80 10～20
