[0021] In one embodiment of the method for forming a light-transmitting waterproof adhesive layer of the present invention, the following steps are included:

[0022] preparing a colloidal mixture comprising a silicone resin, a polymer, a silicate, a surfactant, a photosensitizer, and a functional filler;

[0023] applying the colloid mixture on a treatment piece; and

[0024] The colloid mixture is cured to form a light-transmitting and waterproof adhesive layer on the treated piece.

[0025] In the method of the present invention, a colloidal mixture having specific components, including a silicone resin, a polymer, a silicate, a surfactant, a photosensitizer, and a functional filler, is prepared. This colloidal mixture is then applied to a processed part, such as an electronic product, and cured to form a light-transmitting, waterproof adhesive layer.

The coating thickness can be adjusted based on actual needs. The distance between the spray nozzle and the workpiece surface can also be adjusted based on actual needs.

[0028] After coating, the colloid mixture is naturally cured at room temperature, or rapidly cured under low temperature heating conditions, such as rapid curing in an oven at 50-80° C., thereby forming a light-transmitting and waterproof adhesive layer.

[0029] Finally, the cured light-transmitting waterproof glue is subjected to relevant performance tests, including light transmittance, waterproof performance, high temperature resistance and other indicators.
