example 1

[0017] First, weigh 5g of chitosan and add it to a three-necked flask with a thermometer and a reflux device. Place the flask in a water bath and control the temperature at 80°C. Add 200mL of 10% acetic acid solution by mass to the flask and stir for 5 minutes. Then add 0.3g sodium dodecylbenzene sulfonate one by one, control the temperature at 90℃, stir and react for 10h, then add 200mL deionized water, stir for 5min, stand still, and separate liquids to obtain chitosan dodecylbenzenesulfonate Sodium complex; then add the above chitosan sodium dodecylbenzene sulfonate complex into a three-necked flask with a thermometer and a reflux device, place the flask in a water bath, control the temperature at 70°C, and then Add 10g of tetrahydroxymethyl phosphorous sulfate, 1g of 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride, and 1g of 1-hydroxybenzotriazole, stir and react for 3h to obtain chitosan ten Sodium dialkylbenzene sulfonate quaternary phosphate salt, set aside; ...

example 2

[0020] First, weigh 8g of chitosan and add it to a three-necked flask with a thermometer and a reflux device. Place the flask in a water bath and control the temperature at 85°C. Add 250mL of 15% acetic acid solution by mass to the flask and stir for 8min. Then add 0.4g sodium dodecylbenzene sulfonate one by one, control the temperature at 95℃, stir for 11h, then add 250mL deionized water, stir for 8min, stand still, and separate liquids to obtain chitosan dodecylbenzenesulfonate Sodium complex; then add the above chitosan sodium dodecylbenzene sulfonate complex to a three-necked flask with a thermometer and a reflux device, place the flask in a water bath, control the temperature at 75 ℃, and then in turn Add 15g of tetrakis(hydroxymethyl)phosphorus sulfate, 2g of 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride, 2g of 1-hydroxybenzotriazole, stir and react for 3.5h to obtain chitosan Sodium dodecylbenzene sulfonate quaternary phosphate salt, set aside; then weigh 2...

example 3

[0023] First, weigh 10g of chitosan and add it to a three-necked flask with a thermometer and a reflux device. Place the flask in a water bath and control the temperature at 90℃. Add 300mL of 20% acetic acid solution with a mass concentration to the flask and stir for 10min. Then add 0.5g of sodium dodecylbenzene sulfonate one by one, control the temperature at 100℃, stir for 12h, add 300mL of deionized water, stir for 10min, stand still, and separate the liquids to obtain chitosan dodecylbenzenesulfonate Sodium complex; then add the above chitosan sodium dodecylbenzene sulfonate complex into a three-necked flask with a thermometer and a reflux device, place the flask in a water bath, control the temperature at 80°C, and then in turn Add 20g of tetrakis(hydroxymethyl)phosphorus sulfate, 3g of 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride, 3g of 1-hydroxybenzotriazole, stir and react for 4h to obtain chitosan ten Sodium dialkylbenzene sulfonate quaternary phosphate...

Abstract

The invention discloses a preparation method for a mildew proof plastic and wood material and belongs to the technical field of plastic and wood material preparation. Tetrakis(hydroxymethyl)phosphonium sulfate, 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride and NHydroxybenzotrizole are added into a prepared chitosan sodium dodecyl benzene sulfonate compound, chitosan sodium dodecyl benzene sulfonate season phosphorus salt is obtained and then subjected to high-speed stirring with polypropylene resin, wood flour, vinyl trimethoxy silane and prepared mixed essential oil to obtain a mixture, the mixture is placed into a double-screw pelletizer, particles are obtained and extruded to be formed, and then the mildew proof plastic and wood material is obtained. It proves that an operation process is simple and convenient, no pollution is produced in the preparation process, safety and environment friendliness are achieved, the prepared plastic and wood material cannot mildew under severe environments such as water encountering and humidity, the mildew proof effect is extremely remarkable, the strength and the machinability are remarkably improved, and the mildew proof plastic and wood material can be used and popularized on a large scale.

Description

Technical field [0001] The invention discloses a preparation method of an anti-mold plastic wood material, which belongs to the technical field of plastic wood material preparation. Background technique [0002] Plastic wood materials, also called wood plastic materials, are mainly made of recycled waste plastics such as polypropylene (PP), polyethylene (PE), polyvinyl chloride (PVC), etc., and processed by adding wood flour and other plant fibers . Because plastic wood material combines the many advantages of plant fiber and plastic polymer material, and has both the water resistance and corrosion resistance of plastic and the texture of wood, it has become a building material with excellent performance and very durable, which is widely used in floors and fences. , Chairs and stools, gardens or waterfront landscape, etc., especially for outdoor use. Plastic-wood profiles are waterproof, moisture-proof, and highly environmentally friendly. They can replace wood in a large amoun...
