摘　　要：以八甲基环四硅氧烷、N-β-氨乙基-γ-氨丙基甲基二甲氧基硅烷等为原料,合成了一种侧链取代的氨基硅油(ASO),并将其制成微乳液(ASO微乳液),用作纸张柔软剂。研究发现,随着ASO柔软剂氨值的增加,处理后的纸张柔软度、防水性增加;随着ASO用量的增加,处理后纸张的强度下降。ASO的黏度越大,处理后的纸张越柔软。扫描电子显微镜(SEM)研究发现,用ASO柔软剂处理后的纸纤维显得疏松,所以具有柔软性。An aminoethylarninopropylpolysiloxane is synthesized by the reaction of octamethylcyclotetra siloxane and N-β-（ Aminoethyl ）-γ- aminopropyl methyl dimethoxysilane. The product is emulsified and then used as paper softener. The results showed that the softness and waterproofness of the treated paper increase with the increase of the content of amino groups in the polysiloxane side chain. However, the strength of the treated paper declines when the dosage of aminosilicones in the pulp increases. The viscosity of amino silicones has influence on the paper softness. The higher the viscosity of the aminosilieones is, the softer the treated paper is. The aminosilicone deposited on the paper fibre forms a hydrophobic thin film on the fibre surface, so the SEM observation indicates the treated fibre is more fluffy than the fibre untreated. It is the reason why the treated paper is softer.
