大豆蛋白改性集成材用三聚氰胺-尿素-甲醛树脂
Study on the soy been protein modified melamine-urea-formaldehyde resin for glulam
摘要
Abstract
In order to reduce free formaldehyde content of the synthetic resin, and increase its durability, the modified soy been pro-tein was used to compound copolycondensation melamine-urea-formaldehyde ( MUF ) resin and the basic performances, bonding strength were tested. The results showed that, during the synthetic process of first alkali stage, adding 9% of the soy protein to modi-fy the MUF was the best as the following reasons:the modified resin had an appropriate viscosity which is helped to the production of glulam;lower free formaldehyde content decreased 52% compared to the control. After measuring the mechanical properties and water resistant stripping ratio, the glulam which made by the modified resin have showed good performance reaching the national standard on viscosity and water resistance. The results of 13 C-NMR and FT-IR analysis suggested that soy been protein would hinder the polycondensation reaction. The DMA test analysis indicated that compared with the unmodified MUF resin, the modified resin MUF-1 had lower initial curing temperature and cured more thoroughly and better mechanical properties under the same solidification rate.关键词
