Abstract: The present disclosure relates to hydrophilic silicone rubber serving as a medical catheter and a preparation method and application thereof. The hydrophilic silicone rubber is obtained from polysiloxane containing a nitrile group through a formula design and ultraviolet light irradiation, and can be applied to preparation of silicon rubber medical catheters. The hydrophilic silicone rubber prepared in the present disclosure is cross-linked by ultraviolet irradiation, without a transition metal catalyst, and without metal ion residues. The hydrophilic silicone rubber prepared in the present disclosure can be directly taken as a medical catheter for use, or as a basic formula for use after adding other auxiliary ingredients, so as to meet special needs of various medical places.

Abstract: A temporary high-temperature-resistant dispersing agent, and a preparation and a use method thereof. The temporary high-temperature-resistant dispersing agent is a block high-molecular polymer prepared by a one-step reaction from polysiloxane containing an amino group. The prepared block high-molecular polymer may be directly used as a dispersant; the block high-molecular polymer may also be used as a basic formula and used as the dispersant after other auxiliary compositions are added; and the block high-molecular polymer may also be used in combination with one or more other dispersion auxiliaries and/or surfactants to meet dispersion requirements in various special occasions.

Abstract: This invention relates to a highly flame-retardant adhesive for high-polymer materials. The adhesive contains a phenolic hydroxyl flame retardant which is prepared from organic amino compounds by one-step reaction with simple and controllable synthesis conditions and high synthesis efficiency; and then the highly flame-retardant adhesive can be obtained by blending the flame-retardant and the adhesive. The highly flame-retardant adhesive synthesized in the invention can be directly used as an adhesive for polymer materials to produce high adhesion strength, or used as a basic formula and prepared into composite adhesives through the addition of other fillers, or used as a primer agent to modify surfaces of polymer materials, so as to meet different needs on various special occasions.
