摘要:
为研究有机酸对H发泡剂热分解特性的影响，采用量热仪测试不同质量分数苯甲酸、水杨酸、邻苯二甲酸与H发泡剂混合物的热分解特性参数。结果表明：H发泡剂分解时，随着升温速率增加，外推起始分解温度Te、峰值温度Tp与最大放热速率随之升高。3种有机酸的加入均可以促进H发泡剂的分解，随着有机酸质量分数的增加，其外推起始分解温度和峰值温度呈现同步下降趋势。有机酸熔融生成的H+对H发泡剂分解过程具有显著影响。加入水杨酸能显著降低H发泡剂分解的热释放速率，降低H发泡剂分解过程中的热风险，当水杨酸质量分数达到24%时，较之混有苯甲酸与邻苯二甲酸的H发泡剂外推起始分解温度降低20 ℃。
Abstract:
In order to study the influence of organic acid on the thermal decomposition characteristics of H foaming agent,the thermal decomposition characteristic parameters of the mixture of benzoic acid,salicylic acid,phthalic acid and H foaming agent with different mass fractions were measured by the calorimeter.The results showed that when the H foaming agent decomposed,the extrapolated initial decomposition temperature Te,the peak temperature Tp and the maximum heat release rate increased with the increase of heating rate.The addition of three organic acids could all promote the decomposition of H foaming agent.With the increasing mass fraction of organic acid,the extrapolated initial decomposition temperature and the peak temperature presented a synchronous decrease trend.The H+ generated from the melting of organic acids had a significant effect on the decomposition process of H foaming agent.The addition of salicylic acid could significantly reduce the heat release rate of the decomposition of H foaming agent,and reduce the thermal risk in the decomposition process of H foaming agent.When the mass fraction of salicylic acid reached 24%,the extrapolated initial decomposition temperature of H foaming agent reduced by 20 ℃ compared with that mixed by benzoic acid and phthalic acid.
