Description
Technical field
The present invention relates to bonding articles for use technical field, particularly relate to a kind of for transparent double-sided adhesive tape bonding toughened glass and preparation method thereof.
Background technology
As everyone knows, the display panel of palmtronic is very fragile, under external impact force is impacted, be very easy to damage.Therefore, in order to protect display panel, upper protective film can be covered at the outside surface of display panel.At present, on market, the main toughened glass that uses is as the protective membrane of display panel, is connected to by this toughened glass on display panel and then needs to use glue or adhesive tape.
Existing glue for bonding toughened glass and display panel or adhesive tape transmittance is low, mist degree is high, poor optical properties, transparency are low, weathering resistance is poor, rate of stretching is low, the duration of service of glue or adhesive tape is long apt to deteriorate, cause toughened glass to split away off from display panel, reduce quality and the work-ing life of the display screen of palmtronic.
Summary of the invention
The present invention overcomes above-mentioned defect to provide a kind of for transparent double-sided adhesive tape bonding toughened glass and preparation method thereof, this is used for bonding, and the transparent double-sided adhesive tape transmittance of toughened glass is high, mist degree is low, good in optical property, transparency are high, good weatherability, rate of stretching are high, the duration of service of adhesive tape is long not perishable, make toughened glass and display panel keep bonding, improve quality and the work-ing life of the display screen of palmtronic; This preparation method's technique being used for the transparent double-sided adhesive tape bonding toughened glass is simple, and processing ease, production efficiency is high, is suitable for large-scale promotion application.
For achieving the above object, the present invention adopts following technical scheme.
For bonding a transparent double-sided adhesive tape for toughened glass, comprise the raw material of following weight part:
Soft acrylic's monomer 75 ~ 98 parts
Rigid Acrylic Acid Monomer 1 ~ 25 part
Initiator 0.1 ~ 5 part.
Glass transition temp (Tg) when manufacturing polymkeric substance, can be become the physical property of below-20 degree by the soft acrylic's monomer in the present invention; Meanwhile, soft acrylic's monomer also plays the effect strengthened and keep clinging power.
The content of soft acrylic's monomer is when less than when using when 75 weight part, and the adhesive tape initial stage clinging power obtained has the problem of reduction.On the contrary, when more than when using when 98 weight part, have the problem that weathering resistance weakens and high temperature cohesive force weakens and occur.
Rigid Acrylic Acid Monomer can make, when manufacturing polymkeric substance, glass transition temp (Tg) to be become the physical property of more than 90 degree.The polymkeric substance of rigid Acrylic Acid Monomer forming section under polymerization, forms superpolymer, the cohesive force of adhesive tape is had to the effect of increase together with soft acrylic's monomer above.
The content of rigid Acrylic Acid Monomer, when less than when using when 1 weight part, can produce cohesive force and weaken, weathering resistance reduction, the problems such as clinging power reduction.On the contrary when more than when using when 25 weight part, have the problem generation of the initial stage sticking power reduction of its adhesive tape.
Initiator, when less than when using when 0.1 weight part, has the situation generation of unreacted monomer.On the contrary, occur more than the problem having high molecular decrease in molecular weight when using when 5 weight part.So, because using light trigger, and when polymerization, usually reaction solvent is not used.
Further, this transparent double-sided adhesive tape being used for bonding toughened glass also comprises linking agent, and the weight part of described linking agent is 0.01 ~ 10 part.
Further, this is used for the transparent double-sided adhesive tape bonding toughened glass, also comprises auxiliary agent, and the weight part of described auxiliary agent is 1 ~ 15 part.
Wherein, described auxiliary agent is one or more the mixture in couplant, static inhibitor, ultraviolet screener and antioxidant.
Couplant can increase the steadiness that adhesive tape is combined with product, and adhesive tape is forever combined with product, and bond effect is good.The usage quantity of couplant, when less than when using when 0.1 weight part, the effect imperfection of crosslinked and adhesive performance.On the contrary, occur in the problem reduced more than meeting cohesively when using when 2 weight part.
Static inhibitor prevents function for the electrostatic occurred on the surface of the indicating meter screen board of two sides adhesive tape and portable electronic machine.The usage quantity of anti-electrostatic, when less than when using when 1 weight part, the problem that antistatic effect has reduction occurs.On the contrary, when more than when using when 5 weight part, the problem generation that cohesively reduces is understood.
Wherein, described soft acrylic's monomer be butyl acrylate, butyl methacrylate, n-hexyl acrylate, N-Hexyl methacrylate, Octyl acrylate, n octyl methacrylate, Isooctyl acrylate monomer, Isooctyl methacrylate, different ninth of the ten Heavenly Stems ester and different nonanylmethyl acrylate in one or more mixture.
Wherein, described rigid Acrylic Acid Monomer is one or more the mixture in vinylformic acid, methacrylic acid, maleic acid, fumaric acid, acrylamide, NVP, N-caprolactam, vinyl cyanide, Hydroxyethyl acrylate, Propylene glycol monoacrylate, hy-droxybutyl, the own ester of hydroxyl acrylic and hydroxyacrylamide.
Wherein, described initiator is one or both the mixture in light trigger and thermal initiator, described light trigger is one or more the mixture in benzoin methyl ether, benzoin isopropyl ether, anisoin methyl ether, st-yrax and st-yrax ketal, described thermal initiator is one or more the mixture in benzoyl peroxide, azo-bis-isobutyl cyanide and DMA.
Light trigger and thermal initiator as well used in combination.Only use light trigger, its polymerization efficiency has decline, therefore with thermal initiator molecular weight and the viscosity that can improve polymkeric substance used in combination.
Wherein, described linking agent is one or both the mixture in photocrosslinking agent and thermal cross-linking agent.
Wherein, described linking agent is one or more the mixture in hexanediyl ester, glycol diacrylate, diethylene glycol diacrylate, triethylene glycol diacrylate, propylene glycol diacrylate, propylene glycol diacrylate and tripropylene glycol diacrylate.
The usage quantity of linking agent, when less than when using when 0.01 weight part, has dysgenic problem for cohesive force and weathering resistance.On the contrary, more than when using when 5 weight part, initial stage clinging power and the problem making adhesion physical property low occur.
For bonding a preparation method for the transparent double-sided adhesive tape of toughened glass, comprise following procedure of processing:
Steps A, take the raw material of formula ratio, be placed in different containers respectively;
