Abstract

A photopolymerization reaction system according to an embodiment of the present invention comprises: an ultraviolet lamp; an ultraviolet-transmitting plate disposed under the ultraviolet lamp; and a ventilation part through which air for heat control of the ultraviolet lamp is supplied and discharged, wherein a reactant is supplied below the ultraviolet-transmitting plate to produce a photopolymerization reaction. The photopolymerization reaction system may comprise an air injection module for injecting air supplied through the ventilation part into the space between the ultraviolet-transmitting plate and the reactant so as to prevent the ultraviolet-transmitting plate from being contaminated with by-products generated by the photopolymerization reaction.

Description

technical field [0001] The present disclosure relates to a photopolymerization system, and more particularly, to a photopolymerization system including an air injection module for preventing contamination of a UV light transmissive plate. Background technique [0002] Superabsorbent polymer (SAP) is a special polymer material having excellent water absorption and water retention, and is widely used in baby and adult diapers, feminine products, and the like. Typical methods for producing such superabsorbent polymers include photopolymerization in which polymerization is performed by UV irradiation in the presence of a radical photopolymerization initiator and peroxide. [0003] Photopolymerization is a step performed after aggregation of a monomer composition (hereinafter referred to as "reactant"). Such as figure 1 As shown, when reactants are supplied to the polymerization reactor, the polymerization reaction proceeds in a region below the plurality of UV lamp sets 20 pro...
