Abstract
In this paper,the waste water generated from the production of thermoplastic phenolic resin and the HMM were used to produce the modified phenolic resin by HMM,which is used as a heat-resistant coating material for casting filters,and compound with inorganic gel material such as aluminum sol was also used to prepare inorganic-organic heat-resistant coating composites.By means of determination of residual carbon rate,thermogravimetric analysis and differential scanning method,the influence of the composition of modified phenolic resin by HMM on the heat resistance of modified phenolic resin and the curing process of modified phenolic resin were analyzed,and the factors affecting the performance index of the filter screen were discussed.It was concluded that the optimal composition of HMM modified phenolic resin was that the nitrogen content in solid matter was about 5％,and the optimal composition of the composite coating material was that the mass ratio of HMM modified phenolic resin to liquid aluminum sol was 4∶1,and the aluminum sol was beneficial to improve the heat resistance of the composite coating material,reduced the smoke content of the filter and prevent the fire.关键词
