Description

A kind of environmentally friendly diaphragm for touch-control glass screen and preparation method thereof
Technical field
It is particularly a kind of to be used for touch-control glass screen using ater-soluble adhesive the present invention relates to pressure-sensitive adhesive arts Environmentally friendly diaphragm and preparation method thereof.
Background technology
Pressure-sensitive adhesive product can show viscosity in the case where that need not heat or use solvent, be widely used in mould Cut, electronics, medical science, optics, plating protection and material processing etc..
Touch-control glass screen is to be coated with the pressure-sensitive of high transmission rate with all kinds of optical grade polymeric membrane class base materials with diaphragm at present Adhesive is as functional coat, then is bonded made from Anti adhesive off film.Touch-control glass screen diaphragm applies to pressure-sensitive adhesive agent Layer requirement be:High transmission rate, not cull, cohesive force is high, holds viscosity is good, heat resistance is good etc..So touch-control glass screen is protected Requirement of the cuticula to pressure-sensitive adhesive agent coating is that comparison is strict.
The pressure-sensitive adhesive agent main Types of diaphragm common coatings have (organic) solvent-borne type, emulsion-type, heat molten type etc. at present Several classes.The characteristics of thermotropic pressure sensitive adhesive be adhesive in coating process without using organic solvent, environmental benefit is high, still Cross-link intensity of thermotropic pressure sensitive adhesive itself is poor, and heatproof and hold viscosity energy are bad, and it is bad cull etc. easily occur, so It is not typically used as touch screen diaphragm.Contain substantial amounts of surfactant in emulsion based pressure sensitive gluing agent, this will make emulsion-type pressure Optical property, electric property and the mechanical property of quick adhesive all have undesirable effect;Emulsion based pressure sensitive gluing agent simultaneously is logical Cross between emulsion particle and emulsion particle and be crosslinked to realize cementation, and the adhesive macromolecule inside emulsion particle is typically physics Crosslinking, therefore the cohesive force of emulsion based pressure sensitive gluing agent is poor, typically without in coating touch screen diaphragm.(organic) is molten In formulation pressure-sensitive adhesive agent, adhesive macromolecule is that " free state " is present in organic solvent, passes through appropriate crosslinking side Formula, the macromolecule of these " independences " each other will be cross-linked into network structure jointly, thus resistance to excellent mechanical property and heatproof Hou Xing, so, largely use (organic) solvent pressure-sensitive adhesive to stick the diaphragm of agent coating in touch-control glass screen industry.
However, in environmental consciousness ever-increasing today, the recuperability of environmentally friendly material and material increasingly by To the attention of people, resource, market and environmental requirement more and more higher.And diaphragm class product is belonged to it is difficult to the white rubbish of degraded Rubbish, as long as some species even may have centuries in natural environment!The environment that we depend on for existence is not only degrading, is endangered Evil property is more on the rise with the production and a large amount of use of diaphragm product.
But due to the limitation of fund, technology etc., the diaphragm class product of existing market, it is after use, one As all not as solid dangerous waste but it is many all filled as common rubbish, burn do not make even effectively processing mix with In common dregs of society, this not only seriously pollutes our living space, and also result in the significant wastage of resource.
The common mass share of diaphragm class product about 80%~90% is base material class and the about 10%-20% matter such as film class The pressure-sensitive adhesive agent coating of share is measured, stability of these polymer substances in nature is that diaphragm turns into white pollution thing The main reason for, the particularly indissoluble characteristic of pressure-sensitive adhesive agent coating is dealt with particularly difficult.So some scientific workers Some water miscible adhesive backers are have also been developed, have begun to be applied to be used for plugging into for paper in paper industry.This paper Connecting tape is opened using paper as base material, using water-soluble adhesive layer.After adhesive tape use, can directly it be starched together with waste paper Change.But this connecting tape, because enhancing the water solubility of glue-line, hydrophilic monomer is excessive and alkalization degree is high, causes glue-line Surface free energy is very big, it is difficult to is coated with macromolecule membrane;Simultaneously adhesive molecular weight very little and include more breast Agent composition, so the cohesive force and holding power of adhesive are very low, cull is serious, it is difficult to which the use for reaching electronic protective film will Ask, more can not meet the requirement of touch screen diaphragm.
The processing method of diaphragm substantially has following several ways at present:
1. directly fill or burn:Used diaphragm is directly embedded to garbage disposal landfill yard or burning disposal, this Kind processing method actually still can polluted underground water or atmospheric environment;
2. solid-state dangerous waste is used as, the professional institution's processing that there please be processing qualification:This processing cost is high, processing per ton Fare quote is 4000 yuan to 5000 yuan, and general enterprises are difficult to bear.
3. solvent removes glue-line:The diaphragm tentatively cleaned is soaked with the organic solvent for having certain toxic action, waits to protect After the pressure-sensitive adhesive agent coating of cuticula dissolves or is swelled in organic solvent such as ethyl acetate, toluene, gone with the method for machinery Remove, obtain relatively pure base material, then by base material recycling.The shortcomings that this processing method is:Because using organic Solvent, there is security against fire and occupational health potential safety hazard;Organic solvent price is higher to cause economy unreasonable, makes simultaneously Organic solvent after equally exists pending problem.And generally the functional coat of diaphragm is the pressure sensitive adhesive of cross-linking type, It is difficult effectively to dissolve in organic solvent, cause processing after base material still band glue it is serious, the recovery for being unfavorable for rear road is sharp again With.
4. chemical colloidal sol:The diaphragm tentatively cleaned is reacted to reach under the high temperature conditions with strong alkali solutions such as NaOH Dissolve away the purpose of pressure-sensitive adhesive agent coating.The shortcomings that this processing method is mainly that selectivity is too poor, can only handle polyacrylic acid The diaphragm of esters coating, the diaphragm treatment effect of other kind of type coating is very poor, at the same exist reaction time length, high energy consumption, The problems such as caused sewage is more, film class substrate damage.
5. direct mixing granulation absorption method:After the diaphragm tentatively cleaned is shredded, coetrusion is used in the molten state Directly the diaphragm containing pressure-sensitive adhesive agent coating is granulated, the plastic pellet recycling profit with certain physical property is made With.The characteristics of this method is that the alternative of diaphragm is too narrow.Because the chemical composition of base material and pressure-sensitive adhesive agent coating and The reason for chemical constitution, to the base material using polyolefin and the diaphragms of the adhesives such as SBR can only be coated with carry out coextrusion granulation, And mechanics poor performance;And it is difficult then that coextrusion is granulated to use the diaphragm of non-polyolefin and non-SBR adhesives, so this The limitation of method is very strong.
6. the method that foaming agent is mixed using adhesive:This method is to be added to the foaming agent with certain blowing temperature In pressure-sensitive adhesive agent, after film use to be protected terminates, used diaphragm was entered to certain Temperature Treatment, in pressure-sensitive adhesive agent Foaming agent foam, pressure-sensitive adhesive agent coating is disintegrated from base material and come off, so as to reach recovery base material purpose.It is this Method has specific use condition, and the glass transition temperature point for being primarily due to pressure-sensitive adhesive agent is very low (about -20 DEG C ~-70 DEG C), under the conditions of the blowing temperature of foaming agent, pressure-sensitive adhesive agent coating is in viscous state, foaming agent shape at the beginning of foaming Into gaseous material, quickly pass through pressure-sensitive adhesive agent coating and overflow and dissipate, the foaming condition of foaming agent can not be met at all, cannot The pressure-sensitive adhesive agent coating of foaming, just do not reach yet and pressure-sensitive adhesive agent coating is disintegrated what is come off from base material by foaming effect Purpose.So microcapsule-type foaming agent can only be added using the method that foaming agent is added into glue-line.Using microcapsule foamer The shortcomings that protect film base material recovery, economy was poor it is also obvious that one being the expensive of microcapsule foamer; Two carry out typically above 20 μm of the average grain diameter of microcapsule foamer, so it is difficult to being adopted on the thick diaphragm less than 20 μm of glue With;Furthermore after microcapsule foamer foaming, do not ensure that pressure-sensitive adhesive agent coating can be completely fallen off from base material, this is equally not Effective recovery of protection film base material can be met.
At present CONTINENTAL AREA OF CHINA the diaphragm moon output magnitude be hundreds of millions of square metres, so, no matter be in The angle that environmental protection or resource reclaim recycle, it is necessary to go to find a kind of simple and easy diaphragm with urgency The method of goods, materials and equipments recycling.
