Abstract

The invention relates to preparation and application of polymerizable disulfide capable of reducing volume shrinkage. The synthesis comprises the following steps: adding aliphatic sulfhydrate with reactive hydrogen and sodium iodide into a reactor, adding hydrogen peroxide dropwise under the condition of magnetic stirring and reacting to obtain a product A; and putting the product A and organic alkali into a reaction bottle and adding an acyl chloride compound dropwise under the action of magnetic stirring to obtain the polymerizable disulfide. The preparation and the application of the polymerizable disulfide capable of reducing volume shrinkage have the following beneficial effects: (1) the polymerizable disulfide can obviously reduce the volume shrinkage in the photopolymerization process and provides a new method for reducing volume shrinkage; and (2) the polymerizable disulfide can take part in photopolymerization and also can initiate photopolymerization.

Description

technical field [0001] The invention relates to a preparation method and application of a polymerizable disulfide compound capable of reducing volume shrinkage, and belongs to the technical field of polymer chemical materials. Background technique [0002] UV curing technology is a new type of curing technology developed in the 1960s. Ultraviolet light curing uses ultraviolet light as the curing energy source. After the photoinitiator absorbs the radiation energy, the electrons in the outer layer of the molecule transition to form an active center, which interacts with the reactive groups in the resin, and then initiates free radical polymerization or ion polymerization of the system. Achieve rapid curing. Different from traditional thermal curing, UV curing does not require high-temperature heating, and has the characteristics of fast speed, simple process and equipment, low investment, safety, and environmental protection. Therefore, it is widely used in coatings, adhesiv...
