Problems solved by technology

[0003] Existing light-curing compositions will have the following problems in the actual practical process. When the light-curing process is exposed to the air, the surface of the composition will produce oxygen inhibition. In order to solve the above problems, usually in the composition Add thiol, but for different usage scenarios such as in a sealed environment, thiol compounds are not necessary to add or can be appropriately reduced. Existing photocurable compositions usually directly add thiol compounds to the composition, which is environmentally friendly not tall

Abstract

The invention provides a preparation method of a photocuring composition. The preparation method comprises the following steps: S1, preparing a photoinitiator; s2, mixing a photoinitiator with a first compound to obtain a primary composition, and putting the primary composition into a first cavity of a storage container; and S3, adding a second compound into the second cavity of the storage container, and injecting the second compound in the second cavity into the first cavity for mixing according to requirements during use. According to the invention, the photoinitiator and the first compound are uniformly mixed and then are loaded into the first cavity of the storage container, the second compound containing mercaptan is stored into the second cavity of the storage container, and a proper amount of the second compound is added into the first compound according to actual conditions during use and is mixed and used, so that waste is avoided.

Description

technical field [0001] The invention relates to the field of photocurable compositions, in particular to a preparation method of the photocurable composition. Background technique [0002] Epoxy resin or silicone resin has been widely used as packaging materials for light-emitting diodes to protect internal components of light-emitting diodes due to their light transmission and heat dissipation properties. Existing packaging materials can be classified into heat-curing, light-curing or two-component packaging materials (ie, a combination of light-curing and heat-curing packaging materials) according to their different curing methods. Wherein, the light-curable encapsulation material will undergo free radical reaction or ion reaction after being irradiated with light, so that the resin will undergo cross-linking reaction. [0003] Existing light-curing compositions will have the following problems in the actual practical process. When the light-curing process is exposed to t...
