论述了以醇酸清漆和酚醛清漆为粘结剂的两种耐火涂料的配制工艺,并进行了性能测试.测试结果表明,两种涂料都可提高铸造粘结剂UJK砂型的抗吸湿性、耐火度及铸件表面光粗糙和抗粘砂性;醇酸清漆为粘结剂的涂料综合性能优于酚醛清漆为粘结剂的涂料.
The preparation technology of two kinds of refractory coatings with alkyd varnish and novolak as binder is discussed and the performance test is carried out.The test results show that both coatings can improve the anti-hygroscopicity of the binder binder UJK sand, Degree and cast light rough surface and anti-stick sand; alkyd varnish binder for the overall performance is better than the novolak binder.
