【摘要】 在纯碱Na OH和混合碱(Ca(OH)2/Na OH)降解改性小桐子蛋白的基础上,选取交联剂甲醛对小桐子胶黏剂进行改性。结果表明:单纯碱Na OH处理小桐子制备的胶黏剂不具有耐水性,混合碱(Ca(OH)2/Na OH)处理小桐子蛋白胶黏剂具有一定的耐水性。胶黏剂的性能测试和DSC测试结果表明,无论是单纯碱Na OH,还是混合碱(Ca(OH)2/Na OH)处理小桐子,其蛋白的降解程度有限,导致与后续的甲醛交联反应不理想。更多还原

【Abstract】 Formaldehyde was used as crosslinker to modify Jatropha curcas. protein based on alkali treatment( Na OH and Ca( OH)2/ Na OH). The results showed that Jatropha curcas protein-based adhesive by Na OH treatment had no water resistance,while Jatropha curcas protein-based adhesive by Ca( OH)2/ Na OH treatment had some degree of water resistance. Performance and DSC test results showed that whether pure alkali Na OH,or mixed alkali Ca( OH)2/ Na OH treatment,degradation degree of Jatropha curcas protein was limited,which resulted to subsequently poor cross-linking reaction between degradation Jatropha curcas protein and formaldehyde.更多还原
