Embodiment Construction

[0012] The key of the present invention's success is the preparation of filler, and the requirement of this process is:

[0013] 1.1 Add 40ml of silica gel to the beaker, heat it to 50°C and keep the temperature constant.

[0014] 1.2 Heat the calculated lauric acid crystals to 50°C to melt and prepare 10ml of lauric acid solution with a concentration of 1mol / L, and then heat to 50°C to keep the temperature constant.

[0015] 1.3 Use the gas generator to adjust the gas flow rate and the temperature to 50°C for standby.

[0016] 2 Add 1ml of lauric acid solution to the beaker and stir at a constant speed for 10min.

[0017] 3 10ml of 1,3-butadiene gas was introduced into the mixed solution. Stir at low speed and uniform speed for 10 minutes

[0018] 4 After stirring, the prepared colloid can be obtained, which needs to be filled into the light cone within 15 minutes. The optical glue cures after about 30 minutes.

[0019] All the above steps are completed in a sealed inert...

Abstract

The invention provides an optical filling adhesive capable of increasing light receiving efficiency of a visible-light light cone and solves the problem of low light receiving amount of the visible-light light cone. Total reflection is realized by changing partial refractive index of the light cone, optical escape of visible light is reduced, and the light receiving amount is multiplied. Accordingto a preparation method, lauric acid and 1,3-butadiene are added to silica gel, the materials are stirred uniformly at 50 DEG C for 10 min, the adhesive is prepared, the light cone is immediately filled with the adhesive, and the light receiving amount of the light cone can be increased to 20 times from the original 10 times after the adhesive is cured for 30 min. The preparation method is simpleand easy to operate, and the light receiving effect of the light cone is improved obviously while other optical devices are not affected.

Description

technical field [0001] The patent of the present invention relates to chemical colloid, and relates to an optical glue filled into a visible light cone and a preparation method thereof. Background technique [0002] With the improvement of optical device processing technology and the high integration of application equipment, higher requirements are put forward for the visible light cone. Visible light cones are usually not very efficient, and the amount of light collected can only be increased by less than 10 times. Invent an optical glue that uses the principle of total reflection to prevent incident light from reflecting and escaping, and fill it into the light cone cavity, so that the light reflected at the interface between the colloid and the light cone is reflected back due to the difference in refractive index, and enters the apex of the light cone again. On the basis of the same incident light, the light utilization ratio is greatly improved, reaching an effect of ...
