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.

[0044] Step 2: A 1(1,15) monomer preparation

[0045] In a three-necked flask, add 4.285g (0.01mol) of bromide-1-hexadecyl-5-methyl-2-pyridinemethanol quaternary ammonium salt, 0.060g (1wt%) of inhibitor p-benzoquinone and 0.041 g (0.4wt%) of catalyst triethylamine, add 50ml of acetone for ...

Abstract

The invention discloses an antibacterial (meth)acrylate monomer containing pyridine quaternary ammonium salt and a carbamate structure, a preparation method and application thereof. The antibacterial (meth)acrylate monomer containing pyridine quaternary ammonium salt and carbamate structure prepared by the invention can be used as an antibacterial additive for methyl vinyl silicone rubber. The characteristic of this monomer is that it contains a reactive (meth)acrylate structure, which can participate in vulcanization during the vulcanization process of methyl vinyl silicone rubber, and form a chemical bond with methyl vinyl silicone rubber, thus endowing methyl vinyl The long-term antibacterial performance of the base silicone rubber does not affect the normal use of the silicone rubber.

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...
