Open Data Verified Data
uncured furfuryl alcohol resin is a red viscous liquid, soluble in common organic solvents such as acetone, alcohol, ether, etc., but insoluble in benzene. It can be well mixed with many plasticizers, thermoplastic resins, thermosetting resins, rubber and so on. After curing, it is an insoluble solid polymer. Resistance to general acid and alkali, but not resistant to strong oxidative acids such as nitric acid, chromic acid and so on. Good water resistance, resistance to organic solvent erosion, high heat resistance. Furfuryl alcohol resin and porous materials such as ceramics, graphite, asbestos, wood and other good adhesion, filled with these materials can be made into furfuryl alcohol filled plastic, but also can be formulated into anti-corrosion mortar and coatings. The tensile strength of the resin cured at room temperature is 10.68MPa, the bonding strength to wood is 6. 57MPa, and the bonding strength to steel is 1. 38MPa. Furfuryl alcohol resin glass fiber reinforced laminated plastic properties: density 1.6~1. 8g/cm3, dielectric constant (106Hz) 4~6, volume resistivity l010 ~ 1012 Q.cm, dielectric loss tangent 0.02~0. 04. The use temperature of furfuryl alcohol resin coating is 60 ℃, the use temperature of glass fiber reinforced lining is about 120 ℃, and the maximum use temperature of glass fiber reinforced plastic is 175 ℃.

FURFURYL ALCOHOL RESIN - Reference Information
| EPA chemical information | Information provided by: ofmpub.epa.gov (external link) |
| Overview | Furan resin (Furan resin), also known as furan alcohol resin, with a general term for furan ring resin, is mainly made of furan alcohol or furfural under the action of strong acid The thermosetting resin prepared by polycondensation and containing furan ring (HCHCCHCO-) on the molecular chain, there are mainly furfuryl alcohol resin, furfural resin, furfurone resin, furfurone aldehyde resin, furfurone resin. Strong acid and alkali resistance, chemical resistance, heat resistance, can be used at 180~220 ℃ for a long time, but the toughness is poor, brittle, need to be modified. furan resin is mainly used as adhesive, cleaning, cement, laminated molded plastic products, especially as cast sand core adhesive, corrosion-resistant coating, lining, pipeline, valve, pump parts, etc., and is used as radioactive material in atomic energy industry. |
| resin profile | Chinese name: furan resin Chinese alias: furfuran alcohol resin English name: furan resin molecular structure: resin containing furan ring |
| Synthesis method | Furfuryl alcohol resin: Furfuryl alcohol is prepared from furfural and polycondensed under an acidic catalyst (hydrochloric acid, sulfuric acid, FeCl3). furfurone resin: it is formed by reacting furfural and acetone with equal gram equivalent under NaOH catalysis at 40~60 ℃ to form monomer, neutralizing with acid at 70 ℃ for 1h, then neutralizing with alkali and dehydrating by vacuum heating. furfurfurone aldehyde resin: formaldehyde is added to furfurfurone and reacted at 100 ℃ under sulfuric acid catalysis. |
| preparation and modification | new furan resin is prepared by polycondensation of furfuryl alcohol and furfural under the catalysis of oxalic acid. research shows that when m (furfuryl alcohol):m (furfural) = 7:3, oxalic acid dosage = 0.33% of raw material quality, reaction 3.5h (reflux temperature), the viscosity of the prepared resin reaches 78s, which is well mixed with sodium silicate. The use of benzoic acid as curing agent after curing has excellent water resistance and high temperature resistance, so as to achieve the purpose of modifying water glass cement. Urea-formaldehyde furan resin was synthesized by polycondensation using urea and formaldehyde instead of all furfural and most furfural alcohol. The results show that when n (urea) ∶n (formaldehyde) ∶n (furfuryl alcohol) is 3 ∶ 1 ∶ 2 and reacts at reflux temperature for 3.5h, the modified furan resin with better available value is better than that. |
| research and application | based on the research results of many people in China, many new furan resins developed at present have moderate viscosity and small shrinkage after curing, high bonding strength, high bonding strength, suitable viscosity, strong anti-corrosion performance, short curing time, low viscosity, high strength, low production cost, simple synthesis process, fast hardening speed, low nitrogen content, low free aldehyde, etc. It has achieved good technical and economic benefits in the anti-corrosion engineering application of bonded granite, cast stone plant and sewage treatment plant in sewage. Zhang Xiaoping and others have developed a new type of modified furan resin sand fixing agent. It has been applied to the gas field in eastern Qinghai and has achieved good sand fixation and sand control effects. according to the application in chemical industry and other industries, furan resin can be divided into furan resin glass fiber reinforced plastic, furan resin cement, furan resin graphite products and other aspects. In the application of furan resin, there are mainly furan resin glass fiber reinforced plastic and furan resin cement. With the development of modern foundry industry, furan resin self-hardening sand is made by mixing furan resin, curing agent, raw sand and other raw materials, and its application in foundry production is increasing. |
| development trend | in recent years, the technological research and application of furan resin have developed rapidly. with the emergence of new modified furan resin, the anti-corrosion performance of furan resin has been enhanced and the curing time has been shortened. with the development of new synthesis process and other technologies, the research field and application scope of furan resin have been broadened. Although the research on furan resin has developed rapidly in recent years and some progress has been made, there is still a lot of research work to be carried out. |
