Description
Technical field
The present invention relates to a kind of UV-curing technology fields, solidify black glue more specifically to a kind of ultraviolet light
Glutinous agent and preparation method thereof.
Background technique
LCD screen edge sealing tradition but with narrow frame, the development trend of ultra-narrow frame, and is produced into hot melt adhesive
Sheet, efficiency, effect etc. reason, ultraviolet cured adhesive start to gradually replace the application of traditional hot-melt adhesive.And black is ultraviolet
Optic-solidified adhesive is faced with the relationship that shading performance is contradicted with curing depth compared to general transparent ultraviolet cured adhesive, because
And needing to find one has preferable shading performance while having the ultraviolet light of certain curing depth to solidify black adhesive
Formula and preparation method.
Summary of the invention
The technical problem to be solved in the present invention is that in view of the drawbacks of the prior art, providing a kind of ultraviolet light solidification black
Adhesive and its method.
The technical solution adopted by the present invention to solve the technical problems is: a kind of ultraviolet light solidification black adhesive is constructed,
It is formed including following material and weight ratio: 30-60 parts of acrylic polymer, 20-50 parts of acrylic monomers, 0-2 parts of thixotropic agent,
5-10 parts of photoinitiator, 0.1-1 parts of black dyes.
In implementing the preparation method that ultraviolet light of the invention solidifies black adhesive, the ultraviolet light solidifies black glue
The preparation method of glutinous agent includes the following steps:
1) acrylic ester prepolymer and acrylic monomers are mixed, is stirred 1 hour, control 25-40 DEG C of temperature；
2) photoinitiator stirring is added until being completely dissolved, controls 25-40 DEG C of temperature；
3) black dyes and thixotropic agent is added, stirs 1 hour respectively, controls 25-40 DEG C of temperature.
Implement ultraviolet light solidification black adhesive of the invention, has the advantages that the present invention has preferable hide
Optical property can preferably meet the edge sealing purposes of LCD screen, while have both certain curing depth, and simple production process is easy behaviour
Make.
