Abstract

The present invention provides a coating material, a composite material, a leakage plate support beam and a leakage plate support beam preparation method, wherein the coating material comprises, by mass, 15-40% of zircon product, 20-50% of alumina, 5-20% of glass powder, 5-15% of aluminum phosphate, 3-8% of potassium hydroxide, and 20-30% of water. The leakage plate support beam comprises a leakage plate support beam heat resistance alloy substrate and a coating material layer compounded on the leakage plate support beam heat resistance alloy substrate surface, wherein the coating material is coated to form the coating material layer, and the coating material layer of the leakage plate support beam makes the leakage plate support beam have excellent corrosion resistance and prolonged service life. According to the present invention, with the leakage plate support beam, the leakage plate pollution can be prevented; the leakage plate support beam is not conductive so as not to cause short circuit of the leakage plate, the heat transfer capability of the leakage plate can be reduced, the high temperature resistance can be improved, and the deformation due to the heat static pressure can be reduced; and the experiment results show that: no corrosion trace exists after the leakage plate support beam is used for 8-12 months, and the deformation due to the static pressure does not exceed 3 mm.

Description

technical field [0001] The invention relates to the field of leaky board joists, in particular to the technical field of a coating, a composite material, a leaky board joist and a preparation method thereof. Background technique [0002] The bushing plate is one of the main devices in glass fiber production, and its shape is a trough container. The leakage plate is mainly composed of the following parts: 1. Bottom plate, on which there are required number of leakage nozzles; 2. Side wall; 3. Plug; 4. Terminals, also known as electrodes; 5. Filter screen; 6. , Flange, etc. During the wire drawing process, the molten glass flows into the bushing, adjusted to a suitable temperature, and then flows out through the nozzle on the bottom plate, and is drawn into continuous glass fibers by a high-speed rotating wire drawing machine at the exit. Commonly used bushing plate main materials include platinum, platinum-rhodium alloy, and dispersion-strengthened platinum alloy. [0003]...
