大豆蛋白改性脲醛树脂胶的合成及降解性研究
Synthesis and biodegradation characteristics of urea-formaldehyde resin modified with soy protein
摘要
Abstract
The object of this research was to provide a new approach for improving the adhesion performance of UF adhe-sive by modification with a small amount of soy protein. The optimum addition level of soy proteiniselate( SPI) , as well as the adhesion performance, such as the bonding strength, free formaldehyde content and conformation change of SPI/UF adhesive had been investigated by the orthogonal balance block test of L9(34).The thermal performance of SPI/UF copolymer resin was characterized by differential scanning calorimetry, and the biodegradability of SPI/UF resin was pre-liminarily analyzed. The results showed that the bonding strength of SPI/UF resin was 1.16 MPa in the condition of hy-drolysis at 85 ℃ for 40 min and urea substitution ratio of 15% by SPI. Thermal stability of the resin increased through SPI modification. A small amount of fungus colonies had become visible in the surface of SPI/UF resin after inoculation of microorganisms, which indicated the modified resin had gained a certain degree of biodegradability.关键词
