Abstract

The invention discloses a UV photocuring multifunctional epoxy reactive diluent and a preparation method thereof. The preparation method comprises the following steps: under the protection of inert gas, mixing tetramethyl tetravinyl cyclotetrasiloxane, an organic silicon end-capping reagent and a catalyst to carry out hydrosilylation reaction, and after the reaction is finished, adding allyl glycidyl ether to carry out hydrosilylation reaction to obtain the UV photocuring multifunctional epoxy reactive diluent. The preparation method has the advantages that the preparation method is simple and efficient, and the prepared UV photocuring multifunctional epoxy reactive diluent can greatly improve the curing rate of cationic photocuring and is particularly suitable for a photocuring system taking epoxy group-containing organic silicon or organic fluorine-silicon photocuring resin as a main component.

Description

technical field [0001] The invention relates to the technical field of organic synthesis, in particular to a UV photocurable multifunctional epoxy reactive diluent and a preparation method thereof. Background technique [0002] UV-curable coating is an environmentally friendly coating based on ultraviolet radiation curing technology. Under the irradiation of ultraviolet light, it can be cross-linked and cured in a short time to form a coating with excellent mechanical properties. Compared with traditional solvent-based coatings, UV-curable coatings have less emission of organic volatile components, and have the advantages of environmental protection and energy saving. [0003] At present, UV curing methods can be roughly divided into two categories: free radical photocuring and cationic photocuring according to the curing mechanism. Among them, compared with the free radical photocurable system, the cationic photocurable system has the advantages of being less susceptible t...
