Abstract : the mixed salts of diethanolamine and sodium of lauramidoethylene sulfosuccinate is prepared to modify the products with the mixture of the diethanolamine and hydrogen sulfite of sodium as sulphonating agent. the transparency problem of the product is solved. the result of investigation illustrates the major physocochemical properities of the products after the modifying are basically corresponding to the one before the modifying, and the products have a strong containing salt ability, it is fit to compound the products of the high salt content
文摘:採用亞硫酸氫鈉與二乙醇胺的混合物作磺化劑,對琥珀酸月桂酰胺基乙酯磺酸鈉進行改性,制得了鈉與二乙醇胺的混合鹽,改善了產品的透明度.性能分析表明:改性前後其主要表面物理性能基本相當,且改性后該產品具有較強的抗鹽能力,適用於含鹽量較高的製品Results show that self - crosslinkable latex at room temperature with high elasticity can be prepared when amount of butyl acrylate is 60 %, and amount of methyl methacrylate is 40 %, and mass ratio of nonionic emulsifier to anionic emulsifer is 3 : 1, and amount of initiator is 0. 6 %, and amount of self - crosslinkable monomer and protective colloid is 2 % and 0. 4 % respectively
研究結果表明:當丙烯酸丁酯的質量為60 % ,甲基丙烯酸甲酯的質量為40 % ,非離子乳化劑和陰離子乳化劑的質量配比為3 : 1 ,引發劑的質量為0 . 6 % ,自交聯單體的質量為2 % ,保護膠體的質量為0 . 4 %時,可以制備出高彈性自交聯乳液。Peg and superfluous aa reaction by complete concatenation method, the esterify production " esterify water " and acid number were mensurated, it shows that the esterify reaction would be processed under 100 esterify temperature and with amine accelerantthe tide of esterify reaction was substantiated by ir. in the ir spectrum, the characteristic peak of hydroxy of peg and carboxyl of aa were weakened. and the ester link of peg was reinforce. the " esterify water " was increased gradually and the acid number of esterify production was debased gradually along with the extent of esterify time and the augmentation of molecular weight of peg
通過聚乙二醇與過量的丙烯酸採用全連續法進行反應,測定酯化產物「酯化水」和酸值等宏觀手段反映出在胺類促進劑、 100的酯化溫度等條件下的酯化進程,而利用紅外光譜( ir )分析所反映的聚乙二醇的羥基和丙烯酸的羧基特徵峰減弱,而pea的酯基特徵峰加強等特徵進一步證實了宏觀手段所表現出來的酯化趨勢:隨著酯化時間的延長和聚乙二醇分子量的增大,產生的「酯化水」逐漸增加,酯化產物的酸值逐漸降低;從酯化時間看,當反應時間達到300min時,酯化物的酸值達到最小,而從ir分析來看,酯化物pea4的羥基峰在300min時減弱到最小, pea23在120min時羥基峰的表現出酯化基本完全。
