Description
Technical field
The present invention relates to optics polarization element technical field, more particularly to it is a kind of high durable with reflection function for LCD
Polaroid pressure sensitive adhesive and the polaroid using the pressure sensitive adhesive.
Background technology
Polaroid main usess are used on LCD liquid crystal displays, are had through pattern, semi-permeable pattern and reflective-mode.
Reflective-mode typically uses aluminium mirror coating, and generally aluminium mirror coating is metallic aluminium coating by vaporization to PET base material (Polyethylene
Terephthalate, abbreviation PET, polyethylene terephthalate, chemical formula are COC6H4COOCH2CH2O, are a kind of normal
The resin seen) up, then by the side with aluminum PSA glue (abbreviation of pressure sensitive adhesive, custom
Claim pressure sensitive adhesive) it is compound on polaroid.
The synthesis of traditional polaroid PSA virgin rubber water is by about 80% acrylate (Acrylate ester) peace treaty
The component such as 20% acrylic acid (Acrylic acid) and 2- hydroxyethylmethacry,ates (2-Hydroxyethyl acrylate) is mixed
React what is produced by certain condition after conjunction, in the glue after organic reaction, also contain certain carboxyl (carboxyl)-COOH,
It is hot and humid (85 DEG C × 85%RH × 500H, 85 degrees Celsius, relative humidity be 500 hours in the environment of 85%) in environment,
Hydroxy-acid group can discharge H+, there is aluminium lamination and bores a hole bad, affect using effect in ion etching aluminium film.
The content of the invention
For weak point present in above-mentioned technology, the technical problem to be solved in the present invention is to provide a kind of to reflection-type
The little pressure sensitive adhesive of polaroid aluminium mirror coating corrosive nature, there is also provided the polaroid made using this pressure sensitive adhesive.
For achieving the above object, the invention provides a kind of high durable pressure-sensitive adhesive for polaroid of reflection-type, pressure-sensitive glue host
Including acrylate component unit as the acrylate polymer of essential building blocks, 2-(Acryloyloxy)ethanol as primary structure
The 2-(Acryloyloxy)ethanol polymer of unit and bridging agent；The percentage by weight of the acrylate polymer is 80%-
85%；The percentage by weight of the 2-(Acryloyloxy)ethanol polymer is 14.8%-19%；The percentage by weight of the bridging agent
0.2%-1.0%.
Wherein, the weight average molecular weight of acrylate polymer is 100000-900000；The 2-(Acryloyloxy)ethanol polymer
Weight average molecular weight 100000-200000.
The viscoelasticity of pressure-sensitive adhesive agent itself and to by the wettability of viscous material surface be produce to pressure-sensitive master
Want reason.As a good pressure-sensitive adhesive agent, it is necessary to meet fast viscous force (A)<Bonding force (B)<Cohesiveness (C)<Glutinous base power (D).
The molecular weight for reducing pressure sensitive adhesive can reduce its bulk viscosity, be conducive to flowing and moistening, so as to improve interface cohesive force.But
When molecular weight is low, cohesive strength is poor, and cohesional failure easily occurs during stripping.Increasing molecular weight can increase the cohesiveness of material, and have
Beneficial to raising adhesive strength, but molecular weight crosses conference retardance moistening and dispersion, so impact and material of the molecular weight to adhesive strength
The property of material is relevant.The adhesive strength of acrylic copolymer increases with the increase of molecular weight, therefore the molecular weight of pressure sensitive adhesive must
Must keep within the specific limits, can just obtaining preferable adhesive property.Main body is done using the polymer elastomer of higher molecular,
Coordinate appropriate low-molecular-weight solvent misture to reduce bulk viscosity, problem above can be solved well.Low-molecular-weight it is poly-
Compound, its mechanical property are typically bad.Pressure-sensitive adhesive agent made by low-molecular weight polymer, although initial bonding strength is sometimes all well and good,
But their peel strength and bonding force be not general high, for electronic beam curing graft polypropylene acid esters, when putting down for polymer
When average molecular weight increases, solidifying the peel strength of post-consumer polymer, bonding force and initial bonding strength all increases, this is because polymer point
Subchain segment length increases, and is conducive to the infiltration with adherend surface.When molecular weight is relatively low, due to peel strength and fast viscous force all
It is low, and all there is cohesional failure when peeling off, actually cannot use as pressure sensitive adhesive, the increase of the performance of pressure sensitive adhesive with molecular weight
And increase, it is therefore necessary to improve molecular weight.Since the bonding force of polymer adhesive increases with molecular weight in low-molecular-weight region
Plus, then peel strength is expected by improving molecular weight to improve.After maximum, peel strength drastically declines, and glues
Connect failure mode and interfacial failure is turned to by cohesional failure, no adhesive stays in base material side.This is because adhesive is cohesion
Power has exceeded adhesive with the bonding force between substrate interface, and under final peeling rate, peel strength is slight with the change of molecular weight, and
It is obvious at high speeds.The adhesive of any molecular weight, for two kinds of failure modes, peel strength is all with peeling rate
And increase.It can thus be seen that must be by the molecular weight control of high polymer in certain scope when pressure-sensitive adhesive agent is prepared.
The composition of high polymer is different, and structure is different, and the optimum range of molecular weight is also different.
In actual production, the weight average molecular weight of general acrylate polymer is 100000-900000, acrylic acid hydroxyl second
During weight average molecular weight 100000-200000 of ester polymer, viscosity can be made between 2000CPS to 8000CPS, can meet fast
Viscous force (A)<Bonding force (B)<Cohesiveness (C)<Glutinous base power (D), is appropriate pressure-sensitive adhesive formula.
