Description
Technical field
The present invention relates to adhesive tape more particularly to one kind for the fixed environmentally friendly shading glue of liquid crystal display and backlight module
Band.
Background technology
With the continuous development of science and technology, the continuous micromation of electronic product, at present, liquid crystal display towards it is light, thin,
Big target development.In general, the assembling of liquid crystal display panel and backlight module on the market, often using shading rubber belt
The edge of liquid crystal panel and backlight module is attached at, makes to be not likely to produce displacement between liquid crystal panel and backlight module, so as to prevent
It rubs between liquid crystal display panel and backlight module, avoids scratching the optical diaphragm of backlight module, be able to ensure liquid crystal
Show the display quality of panel.In addition, shading rubber belt can also cover the extra light sent from liquid crystal panel, to prevent leak-stopping light.
Liquid crystal display just develops towards Rimlessization at present, and the frame of backlight module becomes more and more narrow, and shading rubber belt is using
Most of area is disposed by waste discharge in the process, and only few area use bonds solid in liquid crystal display and backlight module
On fixed.The shading rubber belt used on the market at present mostly uses PET materials, and as base material, PET is difficult under field conditions (factors)
Degradation, this allows for substantial amounts of adhesive tape and is taken as garbage emission into environment, becomes white pollution, in addition the gluing above adhesive tape
Agent mostly containing toxic chemicals such as toluene, ethyl acetates, can cause environment seriously to pollute.
The content of the invention
The technical problems to be solved by the invention are a kind of environmentally friendly shadings that can be degraded of present situation offer for the prior art
Adhesive tape, so as to reduce the dirt of white pollution and chemical toxic substances to environment caused by environment after scrapping of existing adhesive tape
Dye.
Technical solution is used by the present invention solves above-mentioned technical problem：The environmental protection shading rubber belt, including base material and painting
Cover adhesive on the substrate；It is characterized in that：
The weight composition of the base material includes：
The plasticizer be selected from dioctyl phthalate, diisooctyl phthalate, diisobutyl phthalate,
At least one of formamide, glycerine and urea；
The photodissociation agent is selected from least one of aminodithioformic acid iron, manganese stearate and ferric stearate；

The neutralizer is selected from least one of triethylamine, diethanol amine, n-butylamine and 1,2- dimethyl propylamines.
It is preferred that the starch-resin is cornstarch resin；The polyethylene is high density polyethylene (HDPE).
It is preferred that the plasticizer is diisobutyl phthalate and the mixture of formamide, the ratio of the two is 1:3.
It is preferred that the photodissociation agent is aminodithioformic acid iron and the mixture of manganese stearate, the ratio of the two is 2:1.
In above-mentioned each scheme, the base material may be employed following preparation methods and prepare：
By proportioning each component is taken to be added in single screw extrusion machine at 130 DEG C~150 DEG C after melting extrusion again by blowing
Film machine blowfilm shaping most batches to obtain degradable black film base material through cooling afterwards.
Preferably, the ethylene oxidic ester is the mixing of epihydric alcohol methylpropenoic acid ester and tertiary carbonic acid glycidyl ester
Object, the ratio of the two is 1:2.
The neutralizer is preferably 1,2- dimethyl propylamines.
Preferably, following methods preparation may be employed in the adhesive：
After by proportioning acrylate analog copolymer being taken to be warming up to 80~90 DEG C, add in ethylene oxidic ester, 80~90 DEG C,
Constant temperature stirs 25~35min under 120~180rpm, is then cooled to 65~75 DEG C, adds in neutralizer and solvent continues stirring 25
~35min after being eventually adding 8~15min of the crosslinking agent stirring, obtains adhesive.

Low strength.
In adhesive formulation：
When ethylene oxidic ester proportioning is less than 10 parts by weight, adhesive viscosity is big, solid content is low, is unfavorable for being coated with, using tired
It is difficult；When proportioning is higher than 30 parts by weight, after adhesive polymerization, colloid hardens, adhesion strength and the hydraulic performance decline of resistance to reflex action, and can not meet makes
With requiring.
When neutralizer proportioning is less than 8 parts by weight, adhesive dissolving is bad, easily and demixing of solvents；Proportioning is more than 15 weight
During part, adhesive adhesion strength declines, and the effect being permanently fixed is not achieved.
When crosslinking agent proportioning is less than 0.5 parts by weight, adhesive cohesive strength is inadequate, easy degumming；Proportioning is more than 1.0 weight
During part, adhesive adhesion strength declines, and the effect being permanently fixed is not achieved.
Compared with prior art, environmentally friendly shading rubber belt provided by the present invention adds photodissociation using degradable starch resin
Agent prepares base material, and base material can be made to realize degradation under field conditions (factors), then adds ethylene oxidic ester to water soluble acrylic acid adhesive
It is modified, solid content is made in the water soluble acrylic acid adhesive that original solid content is low, viscosity is big and viscosity is suitble to changing for coating
Property water soluble acrylic acid adhesive, and add neutralizer, adhesive made to be dissolved under aqueous solvent well, avoid using chemistry
Pollution, is finally made two-sided shading glue by degradable base material obtained and modified aqueous acrylic acid adhesive caused by organic solvent
Band can realize degradation under field conditions (factors), and environment is polluted without chemical noxious substance；It solves the electronic products such as mobile phone to use greatly
Pollution on the environment problem of degrading is difficult to after amount shading rubber belt waste discharge；And liquid crystal display and backlight mould can be permanently fixed
