氨基醇酸树脂涂料是一种中、高档的装饰性涂料,具有优良的装饰性与保护性,广泛地应用于缝纫机、自行车、汽车、机床、电风扇、电冰箱、灯具、玩具以及一些农业机械等,其产量在国内仅次于自干醇酸树脂涂料,占合成树脂涂料的第二位。由于合成脂肪酸和支链酸改性醇酸树脂问世,氨基醇酸涂料的户外耐久性大幅度提高,并使该涂向不用植物油方向发展。而氨基醇酸金属闪光涂料的出现,则为这类涂料开辟了新的装饰性领域。此外,高交联度、低粘度的六甲氧甲基三聚氰胺(HM3),又为该涂料的高固体分化提供了新的途径。氮基醇酸涂料不仅具有优良的综合性能,而且在光泽、漆膜丰满度、施工性能、所用溶剂的种类及用量、原料来源及价格等方面又远远优于丙烯酸类漆。 相似文献

通过选择适当的多元醇、多元酸、脂肪酸,采用脂肪酸法合成短油度醇酸树脂,即直接将多元醇、多元酸、脂肪酸进行酯化生成醇酸树脂。此方法较醇解法操作灵活,控制方便。因为脂肪酸可与多元醇和多元酸形成均相体系,无需进行醇解。并配以低醚化度氨基树脂和部分烷基化氨基树脂,研制出耐候型汽车面漆。检测结果表明,该涂料具有优异的装饰性,鲜亮的光泽,优良的机械性能、化学性能及漆膜耐老化性、高耐候性。该涂料各项技术性能指标达到或超过国内同类产品,具有广阔的应用前景。 相似文献

The conventional air-dried alkyd resin is generally used with 30% to 40% of some organic solvent which dissipates into atmosphere after painting and becomes a factor of air pollution. A reactive diluent was investigated to reduce the content of the organic solvent and to manufacture a high-solid or superhigh-solid paint. 1,1-Bis(1′-methyl-2′-vinyl-4′,6′-heptadienoxy)ethane was found to be suitable as the reactive diluent among the investigated compounds. A small addition of this compound to alkyd paint reduced the content of solvent to less than 15% with a conventional alkyd resin of high molecular weight (high-solid type); and, further, a superhigh solid paint (5% solvent) could be manufactured when this compound was added to a superlong oil-length alkyd resin of low molecular weight. 相似文献

An investigation on synthesis of alkyd resin with sorbitol 总被引:1,自引:0,他引:1

Sorbitol, as an abundant, cheap and renewable resource, is considered as a potential raw material for the manufacture of alkyd resin. In this study, the kinetics on preparation of alkyd resin using phthalic anhydride, sorbitol and soya bean fatty acid as raw materials is investigated. Three kinds of sorbitol based alkyd resins (SAR) samples having fatty acid content (OLf) of 42% (SAR1), 52% (SAR2) and 62% (SAR3) were prepared with phthalic anhydride, sorbitol aqueous solution and soya bean fatty acid using fatty acid method. Kinetic studies showed that the initial and latter stages of the reaction follow a second-order rate law. The second-order rate constants were found to be of the order of 10−5 g/mg KOH/min. Molecular weight and polydispersity index were determined by GPC and end-group analysis. The number average molecular weight of the alkyd resins ranged from 1435 to 1626 and the weight average molecular weight ranged from 3041 to 3648. A large polydispersity index was found in a range from 2.12 to 2.24. The varnish of alkyd resin SAR1 containing 50% 200# solvent gasoline and 1.25% cobalt naphthenate (drying agent) by weight dried faster than the others. The physical and chemical film properties of the sorbitol based alkyd resins were determined and compared with standard alkyd resins. The results showed that the performance of alkyd resin having fatty acid contents (OLf) of 42% (SAR1) was almost the same as the standard alkyd resins. It could be a choice binder for alkyd resin paint and helpful to reduce production cost. 相似文献
