DBP邻苯二甲酸二丁酯 原产地:山东,南韩 溶解度20℃时在水中溶解度小于0.01%,能溶于乙醇、乙醚、丙酮及苯中。与硝酸纤维素、乙基纤维素、聚苯乙烯、聚甲基丙稀酸甲酯、聚乙烯醇缩丁醛、乙酸丁酸纤维素、聚乙酸乙酯、氯乙烯-乙酸乙烯酯共聚物等大多数塑料都有良好的相溶性。主要用作纤维素树脂和聚氯乙烯的主增塑剂。特别适用于硝酸纤维素涂料,具有优良的溶解性、分散性和粘着性。漆膜的柔软性和稳定性亦佳,但阻燃性和耐久性较差,在其中的一般用量为10%-60%(视漆的透明和着色性而定)。本品与颜料相溶性好,用于着色薄膜、人造革和塑料制品时,可以在着色剂分散过程中与蓖麻油一起加入。本品与乙酸纤维素的相溶性较小,增塑作用也偏低。本品还可作为天然橡胶和合成橡胶的增塑剂、软化剂,可提高制品的回弹性。本品的主要缺点是挥发性和油抽出性较大,故耐久性较差。 化学性质DBP在酸或碱催化下,可发生水解反应,生成邻苯二甲酸及其钠盐和丁醇。在高温下DBP能分解成苯二甲酸酐和丁稀,DBP具有一般酯类的其他化学性质。 Product characteristics and USES DBP phthalic acid dibutyl ester Country of origin: shandong, South Korea Solubility of 20 ℃ when the solubility in water is less than 0.01%, soluble in ethanol, ethyl ether, acetone and benzene. With nitrocellulose, ethyl cellulose, polystyrene, poly (methyl propyl dilute acid methyl ester, polyvinyl butyral, cellulose acetate butyrate, ethyl acetate, vinyl chloride/vinyl acetate copolymer, etc. Most plastics have excellent intermiscibility. Mainly used for cellulose resin and polyvinyl chloride (PVC) primary plasticizer. Especially suitable for cellulose nitrate coating, it has excellent solubility, dispersion, and adhesive property. Paint film of the softness and stability is also good, but the flame retardancy and durability is poorer, in which the general dosage is 10% - 60% (depending on the coloration of paint and transparent). This product good intermiscibility with dye, used in color film, artificial leather and plastic products, can be in the process of colorant dispersed with castor oil to join. This product with smaller intermiscibility of cellulose acetate, plasticizing effect is low. This product also can be used as natural rubber and synthetic rubber plasticizer, softener, and can improve the resilience of products. The main disadvantage of this product is volatile and oil extraction sex is bigger, so the durability is poorer. Chemical properties of DBP in acid or alkali catalysis, hydrolysis reaction, generate the phthalic acid and its sodium salt and butanol. DBP at high temperatures can be broken down into dimethyl anhydride and butyl benzene diluted, DBP has generally esters of other chemical properties. |
