Abstract
The invention relates to an adhering technology of a touch screen. The adhering technology adopts a machine casing and the touch screen, before the touch screen and the machine casing are adhered, the adhering surface of the touch screen is roughly processed, and then a bonding agent is adopted to enable the touch screen to be bonded on the machine casing; the rough processing adopts corona processing which comprises the following steps: placing the touch screen between a discharger and a corona roller, and generating a corona between the discharger and the corona roller by utilizing a high-frequency high-voltage power supply, so as to form a low-temperature plasma region; through air ionization between two poles, generating ozone, and changing the molecular structure of the plastic surface of the touch screen. so that the molecular structure is converted into polarity from nonpolarity, small uneven holes are formed in the surface of a material after the corona treatment to enable the surface to be roughened, and further the surface activity is improved. According to the adhering technology disclosed by the invention, before the touch screen is adhered, the adhering surface of the touch screen is subjected to rough processing, the wettability and the adhesiveness can be changed, the adhesiveness of the touch screen and the machine casing is improved, and the adhering quality of a product is ensured.
Description
Technical field
The present invention relates to the touch-screen of electronic product, specifically a kind of attaching process of touch-screen.
Background technology
Electronic product, such as mobile phone, its touch screen base material is PET.PET is a kind of compound substance, containing one or more polymer and multiple additives, as inserts, antioxidant, lubricant, antistatic additive, pigment etc.Although the chemical constitution of the main polymer of plastics (group) determines wettable and the adhesive force of primer, its additive from plastics inner to surface migration, and can affect the surface energy of plastics.So the time that PET deposits is longer, or when the content of some additive (as lubricant) is higher, the change of its surface energy is also larger.
The connection of touch-screen and casing adopts double faced adhesive tape to bond usually.But because on part mobile phone products, shortcoming meets the effective area attached, or the dyne value of touch screen base material does not reach requirement, often cause touch-screen bonding problem loosely, thus affect the quality of product.
Summary of the invention
The present invention is directed to the problems referred to above, provide a kind of attaching process of touch-screen, this technique can increase the moistening of product and adhesion property, solves the problem that product adhesive force is not strong.
According to technical scheme of the present invention: a kind of attaching process of touch-screen, comprise casing and touch-screen, described touch-screen, before fitting with described casing, carries out coarse process to the binding face of described touch-screen, then adopts sticker by described touch-screen bonding on the housing.
Described coarse process adopts sided corona treatment.
The step of described sided corona treatment is: be placed between Electrical Discharge Machine and Corona roller by described touch-screen, high-frequency and high-voltage power supply is utilized to produce corona between described Electrical Discharge Machine and described Corona roller, form low-temperature plasma district, by the air ionization between the two poles of the earth, produce ozone, change the molecular structure of described touch-screen frosting, make it be converted into polarity by nonpolar, material surface can be made after corona to be simultaneously that the hole of minute asperities injustice makes its surface coarsening, to increase surface-active.
Described sticker adopts double faced adhesive tape.
Technique effect of the present invention is: the present invention, before touch-screen laminating, carries out coarse process to its binding face, can change its wellability and tack, promotes the adherence of touch-screen and casing, ensures the laminating quality of product.
Detailed description of the invention
For enabling above-mentioned purpose of the present invention, feature and advantage become apparent more, and below in conjunction with detailed description of the invention, the present invention is further detailed explanation.
The present invention is a kind of attaching process of touch-screen, comprises casing and touch-screen, and touch-screen, before fitting with casing, carries out coarse process to the binding face of touch-screen, then adopts sticker to be bonded on casing by touch-screen.
The mode that coarse process is commonly used adopts sided corona treatment.Sticker often adopts double faced adhesive tape.
Sided corona treatment is widely used in does surface treatment to improve the adhesive force of ink, paint, bridging agent and coating to plastics, paper and metal forming.The reason that it is widely adopted be effective, can control and be convenient to grasp.Especially because the efficiency of corona treatment equipment and effect are updated, remain with the process equipment of high yield and synchronously go forward side by side.
Sided corona treatment is a kind of effective means changing many non-absorbability base material surfaces characteristic, ink can be made to have better moistening and adhesion property, i.e. so-called wettable, the basis that Here it is such as ink, primer, coating etc. adhere to PET, paper or metal forming.Wettable determines the ductility of a kind of liquid on a kind of surface of solids.Water droplet becomes a thin water layer at hydrophilic surface with regard to extension, and forms little water droplet lipophilic surface.The contact angle (angle) formed between the tangent line of water droplet extexine and the surface of solids, namely represent the power of this surface wettability, contact angle is larger, and wettability is poorer.Wetability looks chemical composition and surface texture and different.
The step of touch-screen sided corona treatment is: be placed on by touch-screen between Electrical Discharge Machine and Corona roller, utilizes high-frequency and high-voltage power supply to produce corona between Electrical Discharge Machine and Corona roller, forms low-temperature plasma district, by the air ionization between the two poles of the earth, produces ozone.Ozone is a kind of strong oxidizer, can change the molecular structure of touch-screen frosting immediately, makes it be converted into polarity by nonpolar, material surface can be made after corona to be simultaneously that the hole of minute asperities injustice makes its surface coarsening, increase surface-active.After such surface tension gets a promotion, colloid, glue etc. just can penetrate on processed material further, thus reach desirable attaching and gluing effect.
Sided corona treatment has the following advantages: 1, remove absorbed atom and molecule on the surface; 2, promote the contact of atom, promote moistening; 3, promote surface energy, regulate polarity; 4, atom base or the functional group of energy chemically reactive is created.
The present invention is before touch-screen laminating, coarse process is carried out to its binding face, polymer surfaces is after corona suitably processes, its wellability and tack can be changed, the performance of polymeric matrix is then unaffected, thus the adhesiveness promoted adhesive, promote the adherence of touch-screen and hand set machine shell, ensure that client uses the comfort level of mobile phone.Corona treatment techniques cost is low, can resistance, easy to operate and reliability is high.
Above to invention has been the enough detailed description with certain particularity.Belonging to those of ordinary skill in field should be appreciated that, the description in embodiment is only exemplary, make under the prerequisite not departing from true spirit of the present invention and scope change and all should belong to protection scope of the present invention.The present invention's scope required for protection is undertaken limiting by described claims, instead of limited by the foregoing description in embodiment.
