Abstract
The invention discloses an adhesive capable of being subjected to ultraviolet curing and thermocuring. The adhesive is composed of the raw materials in parts by weight: 25-50 parts of a main ingredient, 10-30 parts of urethane acrylate, 3-10 parts of polyethylene oxide diacrylate, 3-10 parts of glycidyl methacrylate, 3-10 parts of tetrahydrofuran methacrylate, 2-10 parts of hydroxypropyl methacrylate, 0.5-1.5 parts of 2,4,6-trimethyl benzophenone, 0.5-2 parts of a thermal initiator, and 0.5-2 parts of an antioxidant. The main ingredient is prepared by the following steps of placing a styrene-butadiene copolymer in a reactor, adding a solvent and heating to 75-80 DEG C, dissolving, then adding a mixed monomer dissolved with an initiator BPO (benzoyl peroxide), performing a polymerization reaction in a protective atmosphere, then adding an antiager D and a chain terminator hydroquinone, extracting the solvent in vacuum, cooling to a room temperature, and discharging. The adhesive disclosed by the invention can be subjected to ultraviolet curing and thermocuring, thus avoiding a curing problem in places which cannot be irradiated by the ultraviolet rays, and improving the quality of products.
Description
Technical field
The present invention relates to the glue paste of a kind of UV curable and thermofixation.
Background technology
Along with the extensive of intelligent machine, panel computer etc. popularized, society is increasing to the demand of touch-screen series products, according to know-why, divide, touch-screen is divided into vector pressure sensing technology touch-screen, resistive technologies touch-screen, capacitance technology touch-screen, infrared technology touch-screen, surface acoustic wave technique and touches five kinds.
Touch-screen in early days in assembling process general adopted adhesives be double sticky tape, utilize mould that adhesive tape is cut into to applicable shape, carry out bonding.Because it is easy to use, the curing flow process without rear end is subject to the welcome of touch-screen manufacturer within very long for some time.
But at first double faced adhesive tape is the problem of transmittance with its inherent defect, and double sticky tape has three interfaces, light run into interface can occur the refraction with the reflection, therefore, transmittance can be affected greatly; Next is to reprocess difficulty, and yield rate is not high; The 3rd is to realize high efficiency power operation.
The appearance of the bonding glue of touch-screen effectively solves these problems, and at first glue layer only has an interface after solidifying, and the light quantity of refraction or reflection greatly reduces, so the transmittance of product promotes greatly.Secondly the touch-screen bonded adhesives can adopt in process of production and first solidify preliminary fixing, fully curing again after the detection performance, has promoted yield rate.The 3rd glue can adopt special mechanical engagement, can enhance productivity.Increasing producer starts to recognize the advantage place of the bonding glue of touch-screen, and therefore the domestic and international demand to the touch-screen bonded adhesives is also increasing day by day.
The ripe bonding glue of touch-screen mostly is single UV curing system in the market, and there has been a problem in this: the UV rayed less than the solidifying of dash area.UV is curing refers to that glue will curing reaction can occur through the irradiation (being ultraviolet irradiation) of UV light, but in actual mechanical process, always having some zones, can't to shine ultraviolet ray be so-called dash area, these regional glue that can't shine UV light there will be curing bad, not curing situation even, this life-time service for touch-screen has been buried hidden danger.Make a search again for head it off has the production adhesive producing producer of some specialties abroad always, but comparatively ripe product is not arranged yet.Therefore, solve the dash area problem of solidification, become the technological difficulties that the urgent need of touch-screen glue industry is captured.
