Embodiment 1

[0068] step 1:

[0069] 98g N-(β-dimethylaminoethyl)-γ-aminopropylmethyldimethoxysilane, 2g 7% sodium hydroxide aqueous solution, 0.5g 1,1-diphenyl-2-(2, Add 4,6-trinitrophenyl)hydrazine to the reactor one by one, reflux at 100°C for 1 hour, slowly distill methanol out, stop the reaction when no more methanol gas overflows, extract the hydrolyzate with toluene, and wash with water To neutrality, the water layer was separated, and the toluene was distilled off under reduced pressure to obtain 61.38 g of linear compound (II), viscosity: 30 mPa·s.

[0070] Step 2:

[0071] Add 98g of D4 and 1g of 7% potassium hydroxide aqueous solution into the reactor in turn, stop the reaction after reflux at 100°C for 1 hour, extract the hydrolyzate with toluene, wash with water until neutral, separate the water layer, and distill under reduced pressure Toluene was removed to obtain 81.27 g of linear compound (III), viscosity: 220 mPa·s.

[0073] 98g (phenyl tert-butyl) me...

Embodiment 2

[0092] Embodiment 2 is the same as steps 1 to 3 of embodiment 1, and steps 4 to 8 are as follows.

[0093] Step 4:

[0094] 30g compound (II), 60g compound (III), 15g compound (IV) and 1g 1,1-diphenyl-2-(2,4,6-trinitrophenyl)hydrazine were added to the reactor, and Dehydration and condensation at 110°C to 150°C for 30 minutes, then slowly add 8g of trimethylmethoxysilane for end-capping degradation reaction, stop the reaction after 4 hours, and remove low boiling substances (< -0.095mPa), obtain high molecular weight block silicone oil (I). Viscosity: 8100mPa·s.

[0095] Step 5:

[0096] At room temperature, 30g of 1307, 15g of Span-80 and 10g of Tween-80 were put into the reactor and dispersed for 30 minutes at 200r / m to obtain a composite emulsifier (V) with an HLB value of 10.4.

[0097] Step 6:

[0098] At 50°C, 65g of linear compound (I) and 17g of composite emulsifier (V) were put into the reactor and dispersed at 200r / m for 10 minutes to obtain 82g of mixture (VI)....

Abstract

The invention provides a skin feeling and hand feeling agent and a preparation method of the skin feeling and hand feeling agent. The skin feeling and hand feeling agent comprises high molecular weight block silicone oil, a composite emulsifier, fumed silica and alkynol A04, wherein a weight ratio among the components is (65-75) to (17-22) to (3-6) to (1-5); the composite emulsifier is composed of iso-tridecanol polyoxyethylene ether, Span-80 and Tween-80 at a weight ratio of (1-3) to (0.1-1.5) to (0.1-1), and an HLB (Hydrophile-Lipophile Balance) value is 8-11; the high molecular weight block silicone oil has a structural general formula of the following formula (I), wherein the structural formula is as shown in the specification, x is 110-150, y is 15-30, and z is 20-40. The skin feeling and hand feeling agent disclosed by the invention can provide a smooth hand feeling and is yellowing resistant.

Description

technical field [0001] The invention relates to the technical field of chemical engineering, in particular to a skin-feeling agent and a preparation method of the skin-feeling agent. Background technique [0002] Hand feel is an important indicator to measure the apparent quality of leather and woodware. With the diversification of product demand and higher requirements for product texture, traditional hand feel agents have been unable to meet the high-quality requirements of the crowd. [0003] Commonly used feel agents include wax feel agents and silicone feel agents. The non-ionic hand feeling agent made from wax has oily hand feeling, strong plastic feeling and poor light and shadow effect. [0004] A silicone hand feeling agent disclosed in the prior art is a hand feel agent mainly composed of silicone, which is usually obtained by ring-opening polymerization of octamethylcyclotetrasiloxane (D4) and modified silicone , and then emulsified. [0005] Another organosili...
