为了扩大柞木的利用范围,提高利用价值,利用不同浓度二羟甲基二羟基亚乙基脲(DMDHEU)及醚化DMDHEU(mDMDHEU)浸渍处理柞木,并在一定条件下使树脂固定于木材内,进而评价浸渍后柞木的甲醛释放量。结果表明:树脂浓度低于15%的DMDHEU树脂和MDMDHEU树脂处理的试材的甲醛释放量分别可达到E1级和E0级用材的要求,均可直接用于室内环境。
In order to expand the utilization range of oak wood and improve its utilization value, the oak wood is impregnated with different concentrations of dimethylol dihydroxy ethylene urea (DMDHEU) and etherified DMDHEU (mDMDHEU), and the resin is fixed on the wood under certain conditions , And then evaluate the impregnated oak formaldehyde emission. The results showed that formaldehyde emission of DMDHEU resin and MDMDHEU resin with the resin concentration less than 15% can meet the requirements of grade E1 and grade E0, respectively, and can be directly used in the indoor environment.
