modified phenol-formaldehyde resin - Names and Identifiers
modified phenol-formaldehyde resin - Introduction
modified phenol-formaldehyde resin is a kind of resin obtained by chemical modification of phenolic resin. It has the following properties:
1. Heat resistance: modified phenol-formaldehyde resin has high temperature resistance and can maintain stability at high temperatures without obvious quality loss.
2. Chemical resistance: modified phenol-formaldehyde resin has good corrosion resistance to common acids, alkalis and organic solvents, and can resist the erosion of chemical media to a certain extent.
3. Mechanical properties: modified phenol-formaldehyde resin has excellent mechanical properties, such as high strength, hardness, etc., which can be adjusted according to requirements within a certain range.
4. Insulation performance: modified phenol-formaldehyde resin has good insulation performance and can be used in the field of electrical insulation materials.
The main uses of the modified phenol-formaldehyde resin include:
1. Modulation adhesive: modified phenol-formaldehyde resin can be used as adhesive, widely used in furniture, wood products, cardboard and other fields.
2. Heat-resistant plastic: modified phenol-formalderesin can be molded into heat-resistant plastic by heating, which is used to manufacture high-temperature resistant plastic products, such as electrical components, industrial heat-resistant appliances, etc.
3. Electrical insulation material: Due to the excellent insulation performance of modified phenol-formaldehyde resin, it is widely used in the manufacture of electrical insulation materials, such as switches, sockets, insulators, etc.
modified phenol-formaldehyde resin is mainly prepared by adding an appropriate amount of modifier (such as certain amino resins, alkyd resins, etc.) to the phenolic resin, and then performing a chemical reaction, the molecular structure of the resin is changed to improve its properties. The preparation method generally includes reaction mixing, dissolution, solidification and other steps.
When using modified phenol-formaldehyde resin, you need to pay attention to the following safety information:
1. modified phenol-formalaldehyde resin may produce harmful gases or dust during processing, and good ventilation conditions should be provided.
2. Avoid direct contact with modified phenol-formaldehyde resin to prevent irritation to skin, eyes, etc.
3. In the operation, should wear appropriate personal protective equipment, such as gloves, goggles, protective clothing, etc.
4. When disposing of waste materials, they should be properly disposed of in accordance with local regulations to avoid environmental pollution.
