Unsaturated polyester resin production equipment

Abstract

The invention discloses unsaturated polyester resin production equipment. The unsaturated polyester resin production equipment comprises a reaction kettle, a cooling tank, a stirring device, a fractionation and recycling device and a spraying device, wherein the reaction kettle communicates with the cooling tank through a discharging tube; the stirring device comprises a stirrer, a transmission mechanism and a motor; the stirrer is arranged in the reaction kettle; one end of the stirrer extends out of the reaction kettle and is in transmission connection with the motor through the transmissionmechanism; the fractionation and recycling device comprises a vertical fractionation column, a condenser and a water storage device; the vertical fractionation column is arranged on the reaction kettle and communicates with the inside of the reaction kettle; the vertical fractionation column is connected with the water storage device through the condenser; and the spraying device is arranged at the top end of the inside of the reaction kettle. The unsaturated polyester resin production equipment is reasonable in structure; uniformity of reaction is improved; thickness and uniformity of the resin are improved; resources are utilized effectively; and thus, the unsaturated polyester resin production equipment is energy-saving and environmentally friendly.

Description

【Technical field】 [0001] The invention relates to the technical field of resins, in particular to an unsaturated polyester resin production equipment. 【Background technique】 [0002] Unsaturated polyester resin is generally a linear polymer compound with ester bonds and unsaturated double bonds formed by polycondensation of unsaturated dibasic acid diols or saturated dibasic acid diols. Usually, the polyesterification and polycondensation reaction is carried out at 190-220°C until the desired acid value (or viscosity) is reached. After the polyesterification and condensation reaction is completed, a certain amount of vinyl monomer is added while it is hot to form a viscous Such a polymer solution is called unsaturated polyester resin, which is widely used in various fields of national economy such as petroleum, chemical industry, pesticide, medicine, dyestuff, electroplating, electrolysis, smelting, and light industry. [0003] The traditional unsaturated polyester resin us...
