Embodiment 1

[0040] Antibacterial methacrylate monomer A containing cetylpyridinium bromide quaternary ammonium salt and carbamate structure 1(1,15)

Embodiment A1

[0041] This embodiment A 1(1,15) The preparation method of monomer comprises the steps:

[0042] Step 1: Preparation of bromide-1-hexadecyl-5-methyl-2-pyridinemethanol quaternary ammonium salt

[0043] Add 6.157g (0.05mol) of 5-methyl 2-pyridinemethanol and 45.801g (0.15mol) of 1-bromohexadecane in a three-necked flask, add 70ml of 1,4-dioxane, and then Under the temperature of ℃, stir and react for 24 hours, cool to room temperature, after the reaction, the reaction product is purified, after the monomers not participating in the reaction are completely removed, vacuum-dried to constant weight to obtain bromide-1-hexadecane Alkyl-5-methyl-2-pyridinemethanol quaternary ammonium salt.

Abstract

The invention discloses an antibacterial (methyl) acrylate monomer containing pyridine quaternary ammonium salt and a carbamate structure as well as a preparation method and application of the antibacterial (methyl) acrylate monomer. The antibacterial (methyl) acrylate monomer containing the pyridine quaternary ammonium salt and the carbamate structure, prepared with the preparation method disclosed by the invention, can be taken as an antibacterial additive for methyl vinyl silicone rubber. The monomer is characterized by containing a (methyl) acrylate structure with reaction activity, and can participate in vulcanization in the vulcanization process of the methyl vinyl silicone rubber and form chemical bonding with the methyl vinyl silicone rubber, thereby endowing the methyl vinyl silicone rubber with the long-acting antibacterial property; meanwhile, the normal use of the silicone rubber is also not affected.

Description

technical field [0001] The invention relates to a reactive antibacterial monomer that can be used for silicone rubber, in particular to a series of antibacterial (meth)acrylate monomers containing pyridinium quaternary ammonium salt and carbamate structure and its preparation method and its application in silicone rubber in the application. Background technique [0002] Because of its excellent physiological inertia, blood compatibility, tissue compatibility, anticoagulant performance, physical and chemical stability and flexibility, silicone rubber has been widely used in all aspects of people's lives, such as computer keyboards, mobile phone cases, Earphones, hydrocephalus drainage devices, intravenous catheters, urinary catheters, artificial throats, artificial tympanic membranes, silicone rubber artificial breasts, etc. have become one of the most widely used and most valuable polymer materials. [0003] However, with the continuous expansion of the application field of...
