Description
Technical field
The invention belongs to the adhesive technology field, particularly a kind of for bonding UV cured adhesive of optics lenslet and preparation method thereof.
Background technology
Optical adhesive is mainly used in gluing together the opticglass part of opticinstrument light path system, so that it satisfies product optical design requirement.Basic demand to optical adhesive is: it is good etc. that high, suitable bonding strength, the volumetric shrinkage of spectral transmittance is little, high temperature performance reaches well chemical stability, has simultaneously good processing performance, to satisfy the requirement of optical element gummed.The kind of existing optical adhesive mainly contains: the optics light-sensitive emulsion that Canada balsam, methyl alcohol glue, optics epoxy glue and UV solidify, especially the optics light-sensitive emulsion that solidifies of UV, owing to adopting the ultra-violet curing technology, select photosensitive functional material to be prepared from, therefore has curing speed fast, high temperature performance preferably, technique is easier, optical property and the characteristics such as mechanical property is good, now replace gradually Canada balsam, methyl alcohol glue, optics epoxy glue, become the first-selection of present optical veneering.
Yet, bonding for the optics lenslet, connect intensity because existing optics UV is gluing too high, string stress is large, make the gummed part be difficult to tear open glue, easily cause the damage of part, and existing optical cement is because viscosity is little, be difficult to satisfy the gummed for the optical element of less non-automatic alignment optical center or size, centre deviation is larger, even adopt relevant accessory, still can not make larger improvement, and efficient is lower, has limited its application in the optics lenslet is bonding.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the object of the present invention is to provide a kind of for bonding UV cured adhesive of optics lenslet and preparation method thereof, gluing to connect intensity too high to solve existing optics UV, the large problems such as glue difficulty, optical element damage of tearing open that cause of string stress, and improve the optical element gummed working efficiency of less non-automatic alignment optical center or size, make gummed Central of the parts and size controlled.
For solving the problems of the technologies described above, the objective of the invention is to be achieved through the following technical solutions:
A kind of for the bonding UV cured adhesive of optics lenslet, the component of being divided by following quality forms: photosensitive resin 100, semi-solid state bisphenol epoxy 150～250, glycidyl ester based epoxy resin 15～25, acrylic ester cross-linking agent 5～15, thinner one 3～5, photosensitizers 2～4 and stopper one 0.5～1.
The component that described photosensitive resin is divided by following quality forms: bisphenol A type epoxy resin 300～360, acrylic or methacrylic acid 45～72, catalyzer 3.45～6.33, stopper 2 2.42～4.22 and thinner 2 20.
Described stopper one all can be Resorcinol with stopper two, or is MEHQ, or is 2,6 ditertiary butyl p cresol, or is 2,5-dimethyl Resorcinol.
Preferably, described acrylic ester cross-linking agent is two senses or trifunctional linking agent, can be Phthalic acid, diallyl ester, Viscoat 295, tripropylene glycol double methacrylate or hexylene glycol double methacrylate.
Preferably, described thinner one and thinner two are reactive thinner or inert diluent, can be dibutyl phthalate or isobornyl acrylate.
Preferably, described photosensitizers is free radical type, cationic or compound system both, can be benzoin dimethylether, it is perhaps the hydroxy-cyclohexyl phenyl ketone, being perhaps hydroxy-cyclohexyl phenyl ketone and diphenyl iodine hexafluorophosphate compound, is perhaps hydroxy-cyclohexyl phenyl ketone and 4-aminomethyl phenyl phenylbenzene sulphur hexafluorophosphate compound.
The present invention provides a kind of described method for the bonding UV cured adhesive of optics lenslet for preparing simultaneously, comprises the steps:
Step 1: preparation photosensitive resin
The there-necked flask that (1) agitator, thermometer, reflux exchanger will be housed is placed on infrared lamp, adds successively the catalyzer of respective amount from beaker one side, stopper two, and thinner two, agitator is started in acrylic or methacrylic acid, and solid is all dissolved;
(2) add again the part bisphenol A type epoxy resin, stir, begin to be warming up to 110 ℃, reacted 0.5 hour;
(3) survey acid number 160-200mgKOH/g, add the residue bisphenol A type epoxy resin, continue reaction, acid number reaches 30-50mgKOH/g, stopped reaction; Do not reach requirement as acid number, continue reaction, until till reaching;
Step 2: preparation tackiness agent
(1) divide by quality and take each component in Erlenmeyer flask, add the acetone heated and stirred to dissolving fully;
(2) use the filter paper secondary filtration in distilling flask;
(3) steam acetone with the vacuum decompression device;
(4) will distill after in matrass colloid pour in the Plastic Bottle of cleaned and oven dry, dress glue capacity is half of volume;
(5) censorship is labelled, warehouse-in.
Tackiness agent index of the present invention is as follows:
| Project | Technical qualification |
| Outward appearance | Light, transparent semi-solid state |
| Degree of cleaning (dust number, individual/cm 3） | ≤8 |
| 1/4 cone penetration (1/10mm) | 20-40 |
