sulfonated ligno-sulfomethylated phenolic resin copolymer - Introduction
Sulfonated lignin formaldehyde resin copolymer (Sulfonated lignin formaldehyde resin copolymer) is a resin material with the following properties:
1. Sulfonation: Sulfonation refers to the lignin and formaldehyde resin copolymer treated with sulfonic acid to make its surface have sulfonic acid groups. Such treatment improves the water solubility and conductivity properties of the resin copolymer.
2. Water-soluble: sulfonated lignin sulfomethyl phenolic resin copolymer has good water solubility, can form a stable glue solution in water.
3. Conductivity: sulfonated lignin sulfo methyl phenolic resin copolymer in aqueous solution has a certain conductivity, can be used for the preparation of electrolyte materials.
4. Thermal stability: The copolymer has good thermal stability and can maintain its physical properties within a certain temperature range.
The application of sulfonated lignin sulfomethyl phenolic resin copolymer is as follows:
1. Electrolyte materials: Due to its good water solubility and conductivity, it can be used to prepare high-performance electrolyte materials, such as fuel cells, batteries and other energy fields.
2. Water treatment agent: In the process of water treatment, the copolymer can form a complex with heavy metal ions, organic matter, etc., and is used to purify and separate pollutants in water.
3. Degradation materials: sulfonated lignin sulfomethyl phenolic resin copolymer can be used as degradation materials, used in biological multifunctional composite materials, with the characteristics of environmental protection.
Preparation method of sulfonated lignin sulfomethyl phenolic resin copolymer:
A common method for preparing the copolymer is to dissolve lignin and formaldehyde in a certain proportion in a suitable solvent, and adjust the pH value, the condensation reaction was carried out under the conditions of temperature and reaction time, and finally the sulfonation reaction was carried out to obtain the sulfonated lignin sulfomethylphenolic resin copolymer.
Safety Information:
in the use of sulfonated lignin sulfomethyl phenolic resin copolymer should pay attention to the following matters:
1. Avoid prolonged contact with the skin, such as accidental contact, should immediately rinse with water.
2. Avoid inhalation of its dust, use should wear protective masks, gloves and other personal protective equipment.
3. Should be stored away from light, dry, ventilated, away from fire.
4. Use in accordance with the correct operating procedures to avoid any potential safety risks.
