Abstract
The invention discloses a kind of pressure-sensitive adhesive for polaroid, component is acrylic acid esters co-polymer, diluent, acrylate and modifying agent.Pressure sensitive adhesive high-temp resisting high-humidity resisting of the invention, mobility are low, are not likely to produce excessive glue phenomenon.
Description
Technical field
The present invention relates to a kind of pressure-sensitive adhesive for polaroid.
Background technique
The full name of polaroid is polarized light piece, and the imaging of liquid crystal display must rely on polarised light, all liquid crystal devices
It is close to the liquid crystal film of overall thickness 1mm that liquid-crystalline glasses form or so by front and back two panels polarized light piece.If having lacked any one
Polaroid, liquid crystal film cannot all show image.The basic structure of polaroid includes: most intermediate PVA film, two layers of TAC film,
Pressure sensitive adhesive, release film and protective film.In order to adapt to use in a liquid crystal display, one layer of pressure sensitive adhesive is enclosed on polaroid,
And it is compound on release film that pressure sensitive adhesive is protected, form porjection type polaroid, when use tears release film off, so that it may convenient
Polaroid is attached on the glass substrate of liquid crystal display by ground.
Pressure sensitive adhesive has a significant impact to the quality and production efficiency of polaroid, must have good adhesive property, compared with
High light transmittance and weatherability.Currently, domestic pressure-sensitive adhesive for polaroid relies primarily on import.And existing polaroid use it is pressure-sensitive
Adhesive be easy to cause fitting or display bad due to its own defect in hot and humid environment, durable so as to cause product
Property is poor, and in addition to this, such pressure sensitive adhesive mobility with higher is easily flowed out from polaroid and polluted.
Summary of the invention
The present invention is intended to provide a kind of pressure-sensitive adhesive for polaroid, which needs high-temp resisting high-humidity resisting, mobility low, is not easy to produce
Raw excessive glue phenomenon.
The present invention is to realize goal of the invention, is adopted the following technical scheme that
A kind of pressure-sensitive adhesive for polaroid, it is characterized in that: each component of the pressure-sensitive adhesive for polaroid is by mass percentage
Composition are as follows: 12~50wt% of acrylic acid esters co-polymer, 45~85wt% of diluent, 1.5~5wt% of acrylate are modified
0.1~1wt% of agent.
Further, the acrylic acid esters co-polymer is by methyl methacrylate, acrylic acid, methyl acrylate, first
Base hydroxy-ethyl acrylate, glyceride is one such or several combined monomer synthesis.
Further, the degree of polymerization of the acrylic acid esters co-polymer is 400~4500.
Further, the diluent is that one or more of ethyl acetate, toluene, n-hexane and acetone press any ratio
The mixing of example.
Further, the acrylate is n-butyl acrylate, methyl acrylate, ethyl acrylate and 2- metering system
The mixing of one or more of sour methyl esters in any proportion.
Further, the modifying agent is acroleic acid modified polysiloxane, carboxy-modified polysiloxanes and epoxy-modified poly-
The mixing of one or more of siloxanes in any proportion.
Pressure sensitive adhesive of the invention is made using conventional fabrication process, concretely: acrylic acid esters co-polymer being added dilute
It releases in agent and stirs evenly, then sequentially add acrylate and modifying agent, stand 1 hour after mixing evenly to get pressure sensitive adhesive.
In the formula system of pressure sensitive adhesive of the present invention: acrylic acid esters co-polymer contains multiple alkenyl groups, has excellent
Adhesion strength and tack；Modifying agent is added, effectively increases the adhesion strength and tack of pressure sensitive adhesive, while improving product
High and low temperature resistance；The diluent of use reduces the mobility of pressure sensitive adhesive, effectively prevents the generation of excessive glue phenomenon.
The beneficial effects of the present invention are embodied in:
Pressure sensitive adhesive of the invention has preferable adhesion strength and tack, also has excellent high and low temperature resistance, can
To keep excellent properties for a long time at a temperature of -50~200 DEG C；And since the polymerizable molecular amount of pressure sensitive adhesive of the present invention is suitable for, make
Its poor fluidity under high temperature environment, is not likely to produce excessive glue phenomenon.It should using the polarisation flake products and use of pressure sensitive adhesive of the present invention
Liquid crystal display weatherability, stability and the optical property of polaroid all greatly improve.Meanwhile pressure sensitive adhesive price of the invention is low
Honest and clean, formula simply, for polaroid and liquid crystal display industry has good impetus.
