Epoxy resin casting body plate preparation method and device

Abstract

The invention relates to an epoxy resin casting body plate preparation method and device. A mold of which the periphery is opened is built through two glass plates, and both mold assembly operation and resin casting-in operation are simple and convenient. The thickness of the mold is controlled through cushion blocks, adjustment is convenient, and the mold can be used for preparing resin casting body plates of which the thicknesses are different. As the mold building mode is simple, adjustment is convenient in the operation process, and the probability of occurrence of defective goods can be decreased. Transparent adhesive tapes are stuck to one side and the periphery of each glass plate, and as the transparent adhesive tapes are made of a hydrophobic material, separation from resins is easy after resin curing and cleaning is convenient. The preparation method of the casting body plates is protected, the most important characteristic lies in that the mold is formed by assembling the two glass plates and the thickness controlling cushion blocks in a simple mode, and adjustment is convenient.

Description

technical field [0001] The invention belongs to the technical field of material molding, and in particular relates to a method and a device for preparing a flat plate of an epoxy resin casting body. Background technique [0002] Epoxy resin, as a thermosetting resin, is widely used in the preparation of composite parts due to its easy molding and processing characteristics. At present, most of the resins used in wind turbine rotor blades are epoxy resins. As one of the main raw materials of blades, the performance of epoxy resin directly affects the quality and quality stability of blades. Therefore, it is necessary to test the mechanical properties of epoxy resin before use. The performance test of the resin cast body directly characterizes the mechanical properties of the resin, and the test data is often used for performance evaluation, structural design and incoming inspection control. [0003] There are two main methods for the preparation of test samples of resin ca...

Problems solved by technology

[0005] In the existing flat plate manufacturing method of pouring body, the cuboid container made of flat glass is inconvenient to operate and prone to the following two errors

One is that due to the poor sealing tape, the partial seal of the container is not tight in the end, and the container needs to be remade. If it is found that the resin is not poured in time, it will be more difficult to correct

The second is that the container is not clamped effectively around the container, and the container is deformed during the curing process after pouring the resin, and the thickness of the final plate is different.

For cuboid containers made of metal molds, firstly, the molds need to be precision-machined, and the cost is high; secondly, the metal molds are heavy and inconvenient to carry; The flat plate requires metal molds with different container gap thicknesses; the fourth needs to be locked with bolts and vacuumed, which is inconvenient to operate and low in efficiency
