A device for continuous casting of epoxy resin-based composite material boards

Abstract

The invention discloses a continuous casting epoxy resin composite panel device and belongs to the field of composite equipment. The casting device comprises a box, a variable-speed motor, a speed reducer and a discharging pipe, wherein the variable-speed motor is connected with the speed reducer. The device is characterized in that the discharging pipe is a hollow cone, a discharge outlet is formed in the top end of the cone, and the bottom of the cone is connected with the speed reducer through a mechanical sealing part and a bearing; a screw rod is installed inside the discharging pipe, and the diameter of the screw rod becomes smaller gradually from the bottom of a cavity body of the cone to the discharge outlet; a feed inlet is formed in the lower end of the bottom of the discharging pipe, a vacuumizing pipeline is arranged at the upper end of the bottom of the discharging pipe, and a pipeline for adding accelerants is installed at the upper end of the middle of the discharging pipe; the outer wall of the discharging pipe is a jacket layer, and the jacket layer is provided with a water inlet and a water outlet. The device is simple in structure, low in energy consumption, high in casting efficiency, stable in quality and especially suitable for industrial application and popularization of epoxy resin composites.

Description

technical field [0001] The invention belongs to the field of composite material equipment, and relates to production equipment of composite materials, in particular to equipment for continuously casting epoxy resin-based composite material plates. Background technique [0002] Epoxy resin (commonly known as epoxy resins) is an epoxy olygomer, which can form a three-dimensional network of thermosetting plastics when it reacts with a curing agent (hardener). Epoxy resins are usually used in a liquid state, and are often cured by warming or heating to achieve the final purpose of use. As a liquid system, epoxy resin has the characteristics of small shrinkage rate during the curing reaction process, and its cured product has excellent adhesiveness, heat resistance, chemical resistance, mechanical properties and electrical properties. It is an application in thermosetting resins. A larger variety. The disadvantage is poor weather resistance and toughness, but it can be overcome...

Problems solved by technology

At present, the equipment for casting and forming epoxy resin-based composite material boards is directly manually discharged from the bottom valve of the reactor into an open mold with a fixed size, which cannot realize continuous production, because the materials will be mixed with air during the discharging process. Into the interior of the material, resulting in the formation of a large number of air bubbles in the product, and impurities in the product due to uneven mixing of the material, which will affect the final appearance and performance of the product and greatly reduce the service life of the product
