Abstract

The invention comprises a flame-retardant resin comprising phosphaphenanthrene compound. The resin comprises unsaturated polyester synthesized by using the components of, by weight, 290-310 parts of propylene glycol, 260-290 parts of maleic anhydride, 140-152 parts of phthalic anhydride, 280-300 of DOPO, and 600-630 parts of styrene. According to the unsaturated polyester resin, DOPO is used for replacing tetrabromophthalic anhydride, such that a finally obtained resin is a non-halogen flame-retardant reactive resin, and resin application range is widened. In the resin components, maleic anhydride with a relatively large proportion is applied, such that the change of maleic anhydride from unsaturated acid to saturated acid caused by the introduction of DOPO is supplemented. Therefore, the reduction of resin activity and composite material mechanical performances are avoided.

Description

technical field [0001] The invention relates to an unsaturated polyester resin, in particular to a non-halogen flame-retardant unsaturated polyester resin containing phosphorous phenanthrene compounds, a process for synthesizing the resin, and the resin can be used in applications where halogens are restricted. Flame retardant products that require or have higher requirements, such as: interior panels and sanitary ware products in aviation and high-speed rail. Background technique [0002] Unsaturated polyester resin (Unsaturated Polyester Resin, UPR) is generally a polycondensation of unsaturated dibasic acid and diol or saturated dibasic acid and unsaturated diol, which has ester bonds and unsaturated double bonds. type polymer compound. The mixture is copolymerized under the action of heat, light or an initiator, and cross-linked to form a solid material with a spatial network structure. As the most widely used thermosetting resin, the products made of it have excellent...
