Embodiment 1

[0014] a) Mix 100g octamethylcyclotetrasiloxane, 145g water and 5g emulsifier fatty alcohol polyoxyethylene ether, shear and pre-emulsify at 2000r / min to form a pre-emulsion;

[0015] b) Put 10g of dodecylbenzenesulfonic acid and 225g of water into a four-necked flask, stir and heat it to 85°C at a speed of 300r / min, and then drop the pre-emulsion prepared in a) into the flask within 2 hours In the system, keep warm for 2 hours;

[0016] c) Next, mix 20g of water, 5g of emulsifier fatty alcohol polyoxyethylene ether and 3g of coupling agent aminosilane coupling agent [N-(β-aminoethyl)-γ-aminopropylmethyldimethoxy Silane] mixed emulsion was dropped into the system b) within 1.5 hours, kept for 2 hours, cooled to 40°C, neutralized and filtered, and discharged to obtain a translucent modified silicone microemulsion product. The fabric treated with the microemulsion has a soft, smooth and plump effect.

Embodiment 2

[0018] a) Mix 100g octamethylcyclotetrasiloxane, 145g water and 5g emulsifier alkylphenol polyoxyethylene ether, shear and pre-emulsify at 1500r / min to form a pre-emulsion;

[0019] b) Put 8g of dodecylbenzenesulfonic acid and 225g of water into a four-necked flask, stir and heat it to 85°C at a speed of 300r / min, and then drop the pre-emulsion prepared in a) into the flask within 2 hours In the system, keep warm for 2 hours;

[0020] c) Next, 20g water, 5g emulsifier alkylphenol polyoxyethylene ether and 3.5g aminosilane coupling agent [N-cyclohexyl-γ-aminopropylmethyldimethoxysilane] mixed emulsion in 1.5 Drop it into the system b) within hours, keep it warm for 2 hours, cool down to 40°C, neutralize and filter, and discharge to obtain a translucent modified silicone microemulsion product. The fabric treated with the microemulsion has a soft, smooth and plump effect.

Abstract

The invention relates to a method for preparing a modified organosilicon microemulsion used as a fabric softener, which comprises: a) rapid emulsifying octamethyl cyclotetrasiloxane water and emulsifier to pre-emulsion, b) getting dodecylbenzene sulfonic acid and water into a reaction tank, stirring and heating to the temperature of 85+ / -5 Deg. C, making the pre-emulsion prepared from a) instil into the said system in 2 h, reacting to 2+ / -0.5 h with respect to heat, c) instilling the mixture emulsion containing water, emulsifier and coupling agents into system b) in 1.5+ / -0.5 h, reacting to 2+ / -0.5 h with respect to heat, cooling, neutralization filtering and discharging to get the products of modified organosilicon microemulsion.

Description

Technical field: [0001] The invention relates to an organosilicon microemulsion, in particular to a preparation method of a modified organosilicon microemulsion for a fabric softener. Mainly used as fabric softener. It belongs to the technical field of chemical additives. Background technique: [0002] Silicone microemulsions play an important role in improving the softness of fabrics in the textile industry. At present, most of the modified silicone microemulsions used as softeners are prepared by a two-step method: first, amino-modified silicone oil is synthesized by bulk polymerization, and then microemulsified with a suitable emulsifier. The labor time required to prepare microemulsions by this method is long and the production cost is high. Invention content: [0003] The object of the present invention is to overcome above-mentioned deficiency, provide a kind of preparation method of the modified organosilicon microemulsion for fabric softener that can save labor ...
