Problems solved by technology

There are few research reports on rare earth doped unsaturated polyester. For example, Zhang Wengong et al. (ZL 200510115407.X) studied a rare earth doped modified unsaturated polyester material and its preparation method. Rare earth alkoxides can be used to Materials with excellent mechanical properties such as low-temperature toughening in a wide temperature range can be obtained by doping unsaturated polyester, but materials with fluorescent properties have not been obtained

Abstract

The invention relates to a preparation method of an unsaturated polyester fluorescent composite material capable of emitting red light. The unsaturated polyester fluorescent composite material capable of emitting red light comprises the following raw materials in parts by weight: 65-96 parts of unsaturated polyester resin, 3-30 parts of crosslinking monomer, 0.1-15 parts of rare-earth fluorescentpowder, 0.1-10 parts of comonomer, 0.1-3 parts of curing agent, 0-3 parts of accelerator, 0.05-2 parts of antioxidant and 0-3 parts of defoaming agent, wherein the sum of the weight percents of the raw materials is 100. The preparation method comprises the following steps: evenly mixing the raw materials, and curing to obtain the unsaturated polyester fluorescent composite material capable of emitting red light. In the invention, the rare-earth fluorescent powder is used as the fluorescent filler; and the comonomer, which can have favorable interactions with both the unsaturated polyester andthe fluorescent powder, is added into the unsaturated polyester to prepare the unsaturated polyester fluorescent composite material capable of emitting red light. The unsaturated polyester fluorescent composite material capable of emitting red light can be used as a polymer fluorescent material or fluorescent marking material.

Description

technical field [0001] The invention relates to a preparation method of an unsaturated polyester resin fluorescent composite material, in particular to a preparation method of an unsaturated polyester fluorescent composite material that can emit red light under ultraviolet light irradiation, and belongs to the technical field of composite materials.
