摘要
以蓖麻油、甘油、邻苯二甲酸酐、费托合成蜡A28及氧化石蜡为原料合成油溶性醇酸树脂蜡。分别考察了聚酯化反应时间,A28蜡及氧化石蜡加入量对中、长油度醇酸树脂蜡酸值、针入度、滴熔点的影响。实验结果表明制备醇酸树脂蜡的较佳配方为:蓖麻油72.1g、甘油21.7g、邻苯二甲酸酐40.5g、A2817.1g、聚酯化反应时间4h,合成的醇酸树脂蜡酸值:18.96mgKOH/g、滴熔点102℃、针入度13.40mm。
By using castor oil, glycerine, phthalic anhydride. Fischer-Tropsch Process wax （A28） or oxidized petroleum wax synthesize alkyd resin wax. Examining the influence of polyesterification time, quantity of A28 and oxidized petroleum wax to acid value, penetration degree, solidifying point of ＇alkyd resin of different oil-length, found the formula of a kind of car wax cavity.The potyesterification time was 4 h.The formula was： castor oil 72.1 g; glycerine 21.7 g; phthalic anhydride 40.5 g; A28 17.1 g. The acid value of alkyd resin wax was 18.96 mgKOH/g; The penetration degree was 13.40 mm; The solidifying point was 102℃.
