Description
Technical field
The present invention relates to field of adhesive technology, and in particular to a kind of acrylate OCA optical adhesive films.
Background technology
OCA (Optically Clear Adhesive) is used for the extraordinary viscose glue of cementing transparent optical element (such as camera lens)
Agent.It is good in 90% or more, cementing strength to require water white transparency, light transmission rate, can cure under room temperature or medium temperature, and have
The features such as cure shrinkage is small.OCA optical cements are one of the raw material of important touch screen.It is that optics acrylic glue is made into no base
Material, then in upper and lower bottom, then respectively one layer of release film of fitting, it is a kind of two-sided fitting adhesive tape of no basis material.
Acrylate OCA optical adhesive films in the prior art, when temperature is relatively low, product easily becomes fragile and follows the string, in temperature
Soften compared with Gao Shiyi and loses practicability.
Invention content
In order to solve the technical problems existing in the prior art, the present invention proposes a kind of acrylate OCA optical adhesive films,
With excellent heat resistance.
The technical scheme is that：A kind of acrylate OCA optical adhesive films, are made of the raw material of following parts by weight：
70-85 parts of acrylate prepolymer body glue, 1-3 parts of curing agent, 2-5 parts of thickener, 1-3 parts of antioxidant, methyl are fine
Tie up 3-5 parts of 2-8 parts of element, 3-5 parts of neutralizer, 4-6 parts of dimerization propionic acid, 1-2 parts of benzotriazole, 2-4 parts of valeric acid and Pencycuron.
As the preferred embodiment of the present invention, acrylate OCA optical adhesive films are made of the raw material of following parts by weight：
74 parts of acrylate prepolymer body glue, 2 parts of curing agent, 4 parts of thickener, 2 parts of antioxidant, 6 parts of methylcellulose, in
With 4.6 parts of 4 parts of agent, 5 parts of dimerization propionic acid, 1.5 parts of benzotriazole, 3.5 parts of valeric acid and Pencycuron.
A kind of preparation method of acrylate OCA optical adhesive films, steps are as follows：
1., to sequentially add in consersion unit acrylate prepolymer body glue, curing agent, thickener, antioxidant, methyl fine
Element, neutralizer, dimerization propionic acid, benzotriazole, valeric acid and Pencycuron are tieed up, it is small to then heat to 140-160 DEG C of reaction 3-5
When, it is then gradually cooled to room temperature, filters out insoluble matter, inflated with nitrogen preserves to obtain coating liquid；
2., under the conditions of 130-150 DEG C, coating liquid is coated on the release carrier film base material of weight using scraper, is then passed through
Baking and curing film forming is crossed to get acrylate OCA optical adhesive films.
Beneficial effects of the present invention are shown：
By rationally designing the component of optical adhesive film and rationally designing preparation technology parameter, the product of preparation is set to have excellent
Different heat resistance still has stronger viscous force stability under the conditions of high temperature and humidity for a long time.
