preparation example Construction

[0018] In one or some embodiments of the present disclosure, a method for preparing polyaminovinyl silicone oil is provided, comprising the following steps:

[0019] 1) Under the condition of inert gas, add basic catalyst and siloxane ring body and heat while stirring and react for a period of time, then add polyaminosilane coupling agent and tetramethyldivinyldisiloxane, and continue to react for a period of time time;

[0020] 2) Then continue to react for a period of time after heating up to obtain a translucent viscous liquid.

[0021] The purpose of this disclosure is to develop a high-viscosity silicone oil material with both vinyl and amino groups. Higher viscosity (10000-80000cp) can enhance flexibility, polyamino can enhance softness and adsorption, and vinyl can improve softness and rubbing fastness. The present invention firstly controls the ring-opening polymerization of the catalyst and the siloxane ring body to form a prepolymer with a certain low viscosity, an...

Embodiment 1

[0045] The present embodiment provides a kind of preparation method of polyamino vinyl silicone oil, comprises the following steps:

[0046] (1) After feeding inert gas, add 1 part of tetramethylammonium hydroxide and 600 parts of octamethylcyclotetrasiloxane, heat to 110°C while stirring, react for 5 hours under this condition, and then add 5 parts Aminoethylaminoethylaminopropyltrimethoxysilane, and 20 parts of tetramethyldivinyldisiloxane, continue to react for 5h;

[0047] (2) Then the temperature was raised to 160° C., the vacuum degree of the reaction system reached 0.09-0.1 MPa, the reaction was continued for 3 hours, and the reaction was terminated to obtain a translucent viscous liquid.

[0048] After cooling, the measured viscosity at 25°C is 80,000, the ammonia value is 0.10, and the appearance is a translucent viscous liquid.

Embodiment 2

[0050] The present embodiment provides a kind of preparation method of polyamino vinyl silicone oil, comprises the following steps:

[0051] (1) After feeding inert gas, add 1 part of tetramethylammonium hydroxide and 600 parts of octamethylcyclotetrasiloxane, heat to 110°C while stirring, react for 5 hours under this condition, and then add 5 parts Aminoethylaminoethylaminopropyltrimethoxysilane, and 12 parts of tetramethyldivinyldisiloxane, continue to react for 5h;

[0052] (2) Then the temperature was raised to 160° C., the vacuum degree of the reaction system reached 0.09-0.1 MPa, the reaction was continued for 3 hours, and the reaction was terminated to obtain a translucent viscous liquid.

[0053] After cooling, the measured viscosity at 25°C is 60,000, the ammonia value is 0.10, and the appearance is a translucent viscous liquid.

Abstract

The invention belongs to the technical field of organic silicon material preparation, and particularly relates to a preparation method and application of polyamino vinyl silicone oil. The preparation method comprises the following steps: 1) under the condition of inert gas, adding a basic catalyst and a siloxane ring body, heating while stirring, reacting for a period of time, then adding a polyamino silane coupling agent and tetramethyl divinyl disiloxane, and continuously reacting for a period of time; and 2) performing heating and continuously performing reacting for a period of time to obtain a semitransparent viscous liquid. The invention solves the problems that in the prior art, an amino silicon oil preparation method is numerous in operation steps and high in manufacturing cost, and softness and yellowing resistance cannot be achieved at the same time.

Description

technical field [0001] The disclosure belongs to the technical field of organosilicon material preparation, and in particular relates to a preparation method and application of polyaminovinyl silicone oil. Background technique [0002] The statements herein merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] Amino silicone oil is a polysiloxane with active amino groups in the side chain or terminal group. In the research of polyorganosiloxanes with organic reactive groups, amino-substituted reactive polyorganosiloxanes are the most deeply studied and most widely used. A broad class. According to the position of the amino group in the silicone oil molecule, amino silicone oil can be subdivided into the following five types: single-end type, double-end type, side group type, copolymerization type, and mixed type. Different amino groups and their positions endow silicone oils with different properties....
