摘要
在酚类生产过程中会产生大量工业废渣,污染环境,研究了用废渣制备的改性酚醛树脂和酚醛防锈漆生产工艺,详述了聚合反应原理,讨论了聚合反应温度、树脂酸值和混合金属氧化物用量对涂料性能影响,结果表明温度220～230℃、反应6～8h,金属氧化物用量0.6%时,涂料综合性能最佳。
A large number of industrial waste residues will be generated in the production of phenol. The serious environmental pollution will be caused when the waste is discharged into the natural environment. The modified phenolic resin and room temperature quick drying phenolic antirust paint were made by waste residue in order to solve pollution. The technolo- gies of the modified phenolic resin and phenolic antirust paint were studied. The principle of polymerization was described. Polymerization temperature, acid value and mixed metal ox- ides level were studied. The best comprehensive properties of the phenolic antirust paint were showed when polymerization temperature was 220-230 ℃, the polymerization time was 6-8 hours and dosage of mixed metal oxides was 0.6 %
