bisphenol A type Epoxy resins have low molecular weight (softening point less than 50 ° C), medium molecular weight (softening point 50~95 ° C) and high molecular weight (softening point greater than 100 ° C). Low molecular weight and medium molecular weight resins are used in the plastics industry, and high molecular weight resins are used in the coating industry.
epoxy resin laminates are mainly used for chemical industry pipes and containers; Automotive, marine and aircraft parts and sports equipment. Casting into the stator, motor housing and transformer in the motor. Immersed into the transformer, coil insulator, capacitor, current meter, rotary switch and cable joint. Epoxy resin coatings include insulating paint, primer, solvent-free paint, ship paint, oil field anti-corrosion paint, calcium-plastic paint and anti-corrosion paint. They are used in addition to the application of pavement, floor, can also be used for chemical equipment, tanks, oil pipelines, sewage pipelines and other anti-corrosion equipment. In addition, it is also possible to cast a large number of laminated molds. The foam plastic can be used as a thermal insulation material, a sandwich material with light weight and high strength, a floating material and a sound-absorbing material for aircraft.
A low molecular weight resin (soft resin) was contained in a tinplate drum at 20kg per barrel. High molecular weight resin (hard resin) in plastic bags or fiber drum, each net weight 20kg. Products should be stored in a ventilated, dry, cool warehouse to prevent direct sun exposure, and should be isolated from the fire source, away from heat, should not be stacked in the open air. Avoid getting wet and soaking in water. And should be stacked with Isolation amino compounds. Non-toxic, non-hazardous materials can be stored and transported. Product storage period is 1 year. After the time limit, it can be re-inspected according to the specified inspection method. If it meets the quality requirements, it can still be used. During transportation and loading and unloading, the container shall be held with light and the container shall be prevented from being broken, and the container shall not be inverted and pressed with heavy objects.
can be used for casting, dipping, encapsulating, potting, molding, laminating, spraying and coating. As the epoxy resin for plastics, molding, molding, lamination and foaming can be used. Casting is mostly used for encapsulation and encapsulation of electronic and electrical equipment and parts, which can reduce mass and volume. The molding was reinforced with china clay, quartz, mica, graphite powder and glass fiber, and was formed by transfer molding. Molding temperature of 150 deg C, with silicone oil as mold release agent. It is suitable for electronic parts that are not suitable for compression. The laminates were impregnated with epoxy resin and molded at 1 50 ℃ and 1. 27~1.37MPA.

Use | Bisphenol A diglycidyl ether (DGEBA) is a light yellow liquid epoxy compound synthesized by polycondensation of epichlorohydrin (ECH) and bisphenol A(BPA). Bisphenol A diglycidyl ether is a monomer for the synthesis of epoxy resin by bulk polymerization. It can be used as an epoxy resin. It has the advantages of good color, low epoxy equivalent, low organic chlorine content and low cost. It is compatible with various hardeners, fillers, etc., and has a wide range of uses, it can be used as a packaging material for various profiles, insulating paints, coatings, adhesives, semiconductors, integrated circuits and other electronic components. used as adhesives, anticorrosive coatings, and also used in casting process used to prepare anticorrosive coatings, insulating paints, adhesives and laminates used in the coating industry to make canned food coatings, agricultural sprayer coatings, silicon steel sheets and enameled wire coatings, etc. used in the coating and food industry used to prepare anticorrosive coatings and insulating paints, used as adhesive, laminated material used for bonding, sealing, lamination and casting of various materials widely used in the preparation of various coatings, such as powder coatings, solvent-based coatings, anticorrosive coatings, etc. used for bonding of various materials, also used as sealing material, laminating and casting material, anti-corrosion coating, etc. mainly used for casting used for laminating products, casting, sealing, adhesive, coating, etc. used as high-strength electrical insulation material, photoelastic material, optical instrument adhesive, etc. used for manufacturing anti-corrosion coating and insulating paint used for large-scale casting, bonding, sealing, lamination, etc. in the electrical industry |
synthesis | industrial synthesis of DGEBA generally includes: the traditional one-step method is to carry out the open-loop and closed-loop reactions of BPA and ECH under the same conditions under the action of alkali; The two-step process uses a catalyst to make BPA and ECH form chloroalcohol ether intermediate first, and then alkali to deHCI to form glycidyl ether. It is estimated that more than 75% of the industrial epoxy resins are DBEGA, which is currently the most common raw material resin. The following is the synthesis of DBEGA, bisphenol A diglycidyl ether. |
