Bubble trap for resin in glass fiber reinforced plastic production device

Abstract

The invention provides a bubble trap for resin in a glass fiber reinforced plastic production device, and belongs to the technical field of glass fiber reinforced plastic production. The bubble trap solves the technical problem that bubbles in resin in an existing glass fiber reinforced plastic production device are not removed completely. The bubble trap for the resin in the glass fiber reinforced plastic production device comprises a bubble elimination barrel and a barrel cover. A vacuumizing pump is fixed to the barrel cover, and an exhaust opening of the vacuumizing pump stretches into thebarrel cover. An overflow box is fixed to the position, close to a barrel opening, in the bubble elimination barrel. A filling pipe is fixed to the barrel cover in a penetrating manner. A filling hopper communicating with the outer end of the filling pipe is fixed to the outer side face of the barrel cover. The inner end of the filling pipe is located over the overflow box. Overflow openings areformed in the two opposite side walls of the overflow box. Two drainage plates in one-to-one correspondence to the overflow openings are vertically fixed to the bottom of the overflow box. The outer plate faces located at the upper ends of the drainage plates are in smooth transition with the outer wall of the overflow box. An outflow pipe is arranged at the position, close to the bottom, of the barrel wall of the bubble elimination barrel. The bubble trap has the advantage of being capable of completely separating the bubbles in the resin.

Description

technical field [0001] The invention belongs to the technical field of glass fiber reinforced plastic production, and relates to a defoamer, in particular to a resin defoamer in a glass fiber reinforced plastic production device. Background technique [0002] FRP generally refers to adding unsaturated polyester, epoxy resin and aldehyde resin matrix with glass fiber. It is light and hard, with high mechanical strength and strong corrosion resistance. It can replace steel and building materials to manufacture parts or build structures, and has a wide range of uses. There are many ways to manufacture FRP. Among them, the pultrusion process is chosen by the majority of manufacturers because of its characteristics of automatic continuous production, the highest production efficiency and low product cost. [0003] The pultrusion process refers to the processing method in which the glass fiber roving or its fabric is pulled by an external force, and is finally transformed into a ...

AI Technical Summary

Problems solved by technology

When entering the glue tank, the air bubbles in the resin need to be removed to avoid voids in the formed FRP. In order to remove the air bubbles in the existing equipment, a defoamer needs to be used. The current defoamer mainly uses a vacuum. Put the resin in the barrel, then vacuumize the barrel, wait for the bubbles to float up, and complete the defoaming; due to the high viscosity of the resin, it takes a long time for the deep bubbles to float up, resulting in defoaming It takes a long time, and some smaller bubbles are difficult to float in the viscous resin due to their small buoyancy, so there are still small bubbles in the resin
