The results of the comprehensive tests show that example 2 meets the requirements in terms of operation and performance of the production process.
The invention has the beneficial effects that:
1. by using a silicone adhesive material (80000c.s, the viscosity of which is 107 glue, dimethyl silicone oil, fumed silica, a ketoxime type cross-linking agent, a coupling agent and a catalyst), the production operation process is simple, and the cost is much lower than that of an imported material;
2. the production period is short, and finished products can be obtained only by 80 minutes for each batch of 780 kg;
3. the index is controllable, and different color requirements can be produced according to the requirements of customers:
(1) bright black, adding carbon black, and accounting for weight parts, 1.8-2.2 parts;

10. A preparation method of a single-component special lens glue is characterized by comprising the following steps: the method comprises the following specific steps:
proportioning, namely proportionally adding 80000c.s viscosity 107 glue and simethicone into a cylinder of a high-speed dispersion machine;
pushing the prepared cylinder into a high-speed dispersion machine, starting up stirring, starting vacuum to a negative pressure value of-0.08 mpa, pumping a quantitative ketoxime type cross-linking agent into the cylinder by using the vacuum, keeping stirring in the period, and connecting a cooling system outside the cylinder;
after the stirring is uniform, the vacuum is relieved, quantitative fumed silica is added into a powder feeding port, the stirring speed is increased, and the stirring state is kept;
and after uniformly stirring, starting vacuum with the negative pressure value of-0.08 mpa, pumping a certain amount of the coupling agent and the catalyst into a cylinder by utilizing the vacuum, keeping stirring during the pumping, and removing bubbles in the vacuum to obtain the single-component special lens adhesive.
