二氯化乙烯中的甲基丙烯酸樹脂浓毛妓女中国HD。

A photosensitive resin for UV curing acrylic powder coating has been synthesized by esterification of methacrylic acid and GMA-type acrylic resin at the presence of ethyl acetate as solvent, tetramethylammonium chloride as catalyst, YK as inhibitor.

以醋酸丁酯為溶劑国产成人精品一区二区不卡，四甲基氯化銨為催化劑，氮氧自由基為阻聚劑国产精品一级艳片无码，由甲基丙烯酸縮水甘油酯類丙烯酸樹脂與甲基丙烯酸酯化反應(yīng)制得了UV固化粉末涂料用感光性丙烯酸樹脂欧美性爱视频亚州。

The result indicated that MgO and α- methacrylic acid can together thicken epoxy, and the speed of thickening epoxy become quickly with the increasing content of MgO; when the ratio of MgO and α- methacrylic acid is 3:1, thickening epoxy have a better effect; the thickening mechanism: the terminal corboxyl group of α- methacrylic acid react with MgO, and it accompany with large numbers of heat, the heat can accelerate the reaction between the terminal corboxyl group with the secondary hydroxyl groups of epoxy, intermolecular hydrogen bonding which the water of above-mentioned formation result in and complex compound which format the metal atoms and carbonyl group complexing collective increase the viscosity of epoxy resin.
