Description

Technical Field

[0001] The utility model relates to the technical field of polyester resin production and manufacturing, in particular to a polyester resin production device. Background Art

[0002] Polyester resin is a general term for polymer compounds formed by polycondensation of diols or dibasic acids or polyols and polyacids, and is divided into saturated polyester resins and unsaturated polyester resins. Unsaturated polyester resins are mainly composed of unsaturated polyester resins, pigments, fillers, initiators and other additives. Unsaturated polyester adhesives are mainly composed of unsaturated polyester resins, which have low viscosity, are easy to wet, and have good processability. The cured adhesive layer has high hardness, good transparency, high brightness, can be quickly cured under pressure at room temperature, has good heat resistance, and excellent electrical properties. However, its disadvantages are large shrinkage, low adhesive toughness, poor chemical resistance and water resistance. It is mainly used for non-structural adhesives, such as for bonding fiberglass, hard plastics, concrete, electrical cans, etc.
