STIRRING EQUIPMENT AND METHOD FOR PREPARING EPOXY RESIN-BASED FLAME-RETARDANT COMPOSITE MATERIAL BY USING EQUIPMENT

WIPO Patent Application WO/2024/074069

A1

The present invention relates to the technical field of epoxy resin-based flame-retardant composite materials, and disclosed in the present invention is a stirring equipment and a method for preparing an epoxy resin-based flame-retardant composite material by using the equipment. The stirring equipment comprises a stirring cylinder and a stirring assembly. In the present invention, raw materials in the stirring cylinder are fully stirred by means of a stirring plate, which is obliquely arranged on a stirring rod, and when discharged, the raw materials on the bottom of the stirring cylinder are fully scraped into a discharging pipe by means of an arc-shaped scraping plate at the bottom of the stirring rod; in addition, a bisphenol A epoxy resin is modified in the preparation method, such that the thermal stability and tensile property of the bisphenol A epoxy resin are enhanced, and the flame retardance thereof is enhanced while the viscosity is reduced; a synthesized anti-precipitation dispersant can prevent polymerization and precipitation among resin components, thereby reducing the viscosity of a resin system; and on the basis of a conventional curing process, low-temperature curing is added, thereby enhancing the curing efficiency and tensile property of the resin.
