Embodiment 1

[0035] Weigh 50g of rosin (first-grade rosin, Jiangxi Huajin New Material Co., Ltd.) and 14g of maleic anhydride and pour them into a 500mL four-neck flask, then add 200mL of acetic acid and 0.126g of p-toluenesulfonic acid as a catalyst, and heat to 120 ℃ condensed and refluxed, stirred to make it fully react, after reacting for 10h, filtered to obtain the maleopimaric acid compound. Then add 50g of maleopimaric acid and 800mL of ethanol into a 1000mL four-neck flask, heat to 85°C to condense and reflux, add 12mL of N,N-dimethylethylenediamine dropwise, after the dropwise addition, react for 5 hours, and stand for crystallization , After filtration, the rosin-based tertiary amine compound was obtained. Then add 20g of rosin-based tertiary amine compound, 80mL of bromoethane and 500mL of tetrahydrofuran into a 1000mL single-necked flask, heat to 65°C, condense and reflux, stir to make it fully react, and react for 36h, and filter the product to obtain a rosin quaternary ammoni...

Embodiment 2

[0037] The preparation of maleopimaric acid compound refers to Example 1. Add 20g of maleopimaric acid and 500mL of ethanol into a 1000mL four-neck flask, heat to 80°C to condense and reflux, add 8mL of N,N-dimethylethylenediamine dropwise, after the dropwise addition, react for 5h, and stand for crystallization. After filtration, the rosin-based tertiary amine compound was obtained. Add 25g of rosin-based tertiary amine compound, 100mL of bromoethane and 400mL of tetrahydrofuran into a 1000mL single-necked flask, heat to 55°C to condense and reflux, stir to make it fully react, and after 24 hours of reaction, filter the product to obtain a rosin quaternary ammonium compound. Add 3g of rosin quaternary ammonium compound, 1.3g of 3-glycidyloxypropyltriethoxysilane, 0.007g of benzyltriethylammonium chloride and 80mL of ethanol into a 250mL single-necked flask, react at 80°C for 6h, After the reaction was completed, the solvent was removed by rotary evaporation to obtain a rosin...

Abstract

The invention discloses a rosin quaternary ammonium salt antibacterial coating compound based on a modified non-woven fabric, and a preparation method and application thereof. The structural formula of the rosin quaternary ammonium salt antibacterial coating compound is as shown in the specification. The rosin quaternary ammonium salt antibacterial coating compound has broad-spectrum and efficientbactericidal performance and is a novel rosin quaternary ammonium salt antibacterial coating compound. According to the preparation method of the rosin quaternary ammonium salt antibacterial coatingcompound, a natural biomass resource, namely rosin is adopted as a raw material and undergoes addition, amidation and the like to synthesize the rosin quaternary ammonium salt antibacterial coating compound; the synthesis process is simple and convenient, the raw material source is green, and a new way is provided for high-valued utilization of rosin resources; and ethanol is used as a solvent, and the compound can be efficiently and chemically grafted to the surface of the non-woven fabric, so the antibacterial property, the mechanical property and the thermal stability of the non-woven fabric are remarkably improved.

Description

technical field [0001] The invention relates to a rosin quaternary ammonium salt antibacterial coating compound based on a modified nonwoven fabric, a preparation method and an application thereof, and belongs to the field of novel fungicides. Background technique [0002] The skin, the largest organ of the human body, acts as a natural barrier and plays an important role in defending against environmental aggressors, but is vulnerable to damage from exogenous factors such as burns, trauma, or other extrinsic hazards. When the skin is injured, the wound must be covered with a dressing to prevent the wound from being infected by bacteria and loss of tissue fluid, so as to promote wound healing. Non-woven fabrics have been widely used as wound dressings, and there are a large number of hydrophilic functional groups in the cotton fiber molecules, which have excellent moisture management properties and can meet the humid environment required for wound healing. However, a warm a...
