Description
Technical field
The invention belongs to glue paste technical field, particularly relate to a kind of liquid optical cement.
Background technology
Liquid optical cement (LOCA) is for the bonding special adhesive of transparent optical element (as optical grade camera lens, touch-screen and liquid crystal display etc.), at present, liquid optical cement is mainly main raw material(s) with epoxy resin, and is cured in single (ultraviolet) mode.But, glue in use, because screen perimeter has light tight ink coating to block uviolizing, screen perimeter glue is caused to realize disposal solidifying, therefore just need to do four side-irradiations, just can reach the effect that whole screen glue all solidifies, so just result in complicated construction technique, the appearance of the problem such as processing time is long, production cost is high and finished product yield is low.
In addition, epoxy resin has the shortcomings such as weathering resistance difference, moisture-proof thermotolerance be poor, uses out of doors and easily loses efficacy.In view of this, necessaryly provide a kind of liquid optical cement, this liquid optical cement has the plurality of advantages such as good weatherability and moisture-proof good heat resistance, and can be cured in conjunction with the heat energy produced during uviolizing while ultraviolet curing, thus solve screen perimeter cannot the phenomenon of one-step solidification, substantially reduce production technique and make the time, reducing finished product fraction defective, play energy-conservation, save time and improve the effect of production capacity.
Summary of the invention
The object of the invention is to: for the deficiencies in the prior art, and a kind of liquid optical cement is provided, this liquid optical cement has the plurality of advantages such as good weatherability and moisture-proof good heat resistance, and can be cured in conjunction with the heat energy produced during uviolizing while ultraviolet curing, thus solve screen perimeter cannot the phenomenon of disposal solidifying, substantially reduce production technique and make the time, reducing finished product fraction defective, play energy-conservation, save time and improve the effect of production capacity.

Light trigger is also known as photosensitizers or light curing agent, it is a class can absorb certain wavelength energy at ultraviolet region (250 ~ 420nm) or visible region (400 ~ 800nm), produce free radical, positively charged ion etc., thus the compound of trigger monomer polymerization crosslinking solidification.
Solidifying agent is added in silicone resin glue paste, be polymerized with interlaminar resin by solidifying agent molecule, can effectively change the performances such as chain structure, space structure, intermolecular distance, thermostability, and make the structure of silicone resin more be tending towards spatial network type.After adding solidifying agent, the present invention can be cured in conjunction with the heat energy produced during uviolizing, thus solve the defect that screen perimeter cannot realize disposal solidifying, substantially reduce production technique and make the time, reduce finished product fraction defective, play energy-conservation, save time and improve production capacity, reduce the effect of production cost, thus compensate for defect when being cured by means of only single ultraviolet curing mode in prior art.
The effect of reactive monomer in liquid optical cement is regulation system viscosity, the wettability of promoting liquid optical cement and adhesives, improves curing speed and improve the various performances of solidifying front and back material, as snappiness and hardness etc.
Silane coupling agent can improve the performances such as the bonding strength of liquid optical cement, water-fast, weather.Antioxidant can prevent liquid optical cement by the dioxygen oxidation in air, light absorber can absorb the ultraviolet part in sunlight and fluorescence light source, and itself does not change, photostabilizer is then a kind of Degradation that can suppress or weaken light liquid towards optical cement, improves its photostabilization.Light absorber and photostabilizer all can improve the ageing resistance of liquid optical cement.
