摘要:本文在传统制作工艺的基础上,在生漆与聚合桐油的混合阶段,引入了高速分散搅拌,研磨两种方法,从而使生漆与聚合桐油的偶连更加紧密,分散更加均匀,从而达到干燥时间短,涂层均匀,性能稳定。试验表明:基于生漆与桐油的成本差距巨大的考虑,按照经济性与技术性相统一的原则,认为在春秋季节,生漆与桐油的最佳搭配比例是4∶6,在夏冬季节,生漆与桐油的最佳搭配比例是6∶4。通过涂刷,涂层表面的物理性能漆膜附着力达到国标1级,抗冲击性60~70 cm,涂层表面硬度达到了国标铅笔2 H,表面光泽度120%,柔韧性10 mm。进行的耐碱性、耐酸性、耐盐性、97﹟汽油、沸水中进行耐腐蚀性以及在200℃时的耐热性的性能测试,表现良好。

Abstract: Based on traditional marking process, in the stage of lacquer mixing polymerized tung oil we introuded two methods of high speed dispersion stirring and grinding polymerized tung oil in order that the lacquer was more tightly connected and more evenly distributed, and the drying time was shorter, and the coating was evenly, and the property was stable. The experiment showed that: Taken the cost difference between lacquer and tung oil in consideration and in accordance with the principles of economic and technical unity, in spring and autumn the best proportion of lacquer and tung oil was 4∶6 and in summer and winter the best proportion of lacquer and tung oil was 6∶4; By brushing, the physical properties of the coating film adhesive to the surface met the national standard level 1 , the impact resistance was 60 ~ 70 cm, the hardness of coating surface is equivalent to that of national standard pencil 2H, the surface gloss was 120%, and the flexibility was 1.0 mm; The performance of alkali resistance, acid resistance, salt tolerance, corrosion resistance in 97# gasoline and boiling water, and heat resistance in 97 # gasoline and boiling water at 200 ℃ is good.

生漆具有漆膜坚硬,富有光泽、耐久、耐磨、耐油、耐水、耐热、耐腐蚀、绝缘、与基底材料表面结合力强等优点 [1,2 ],中国是世界上最早利用生漆的国家,精美的中国漆器是传统的出口商品。桐油,又名木油或中国木油,是由大戟科油桐属种子经压榨或用溶剂浸出制得的干性油,具有干燥快、附着力强 、有光泽、不怕水 、不怕热、不传电、耐酸、防腐等优良特性,故用途非常广泛 [3,4 ]。

在生漆中加入聚合桐油,名曰广漆,又名金漆、赛霞漆、广泛用于漆筷和家具涂装。是我国利用生漆的一种古老方法,传统的加工方法是将聚合桐油与生漆混合即得,往往由于生漆与聚合桐油的混合均匀度不够,形成的涂层表面出现颗粒、退色等不良现象,影响了其涂层的装饰效果。……
