Embodiment Construction

[0028] The present invention will be further described in detail below in conjunction with examples, so that those skilled in the art can implement it with reference to the description.

[0029] An embodiment of the present invention provides a method for improving the appearance chroma of a synthetic mica board, comprising the following steps:

[0030] (1) Through sizing, the silicone water (organic silicone resin + toluene + methanol) is evenly penetrated into the mica paper, and the mica paper is a synthetic mica paper;

[0031] (2) Part of the toluene and methanol in the glued paper are volatilized by baking, and the toluene and methanol in the organic silica gel water are initially volatilized through the front section of the oven at 20-60 °C, and the toluene and methanol in the organic silica gel water are further volatilized through the middle section of the oven at 60-100 °C. Volatilization, through the end of the oven at 100-140 °C, the remaining toluene and methanol ...

Abstract

The invention belongs to the field of mica plate preparation and provides a method for improving the appearance chromaticity of a synthetic mica plate. The method comprises the following steps of by using a mica material and organic silica gel water as main materials for preparation, increasing the number of pieces of glass fiber cloth in the blank plate stacking process, lowering the pressing temperature, adjusting the pressing exhaust frequency and the like. The method is advantaged in that the prepared mica plate has excellent temperature resistance grade and high strength performance, appearance chromaticity is improved, and meanwhile, the mica plate has good processability and use performance.

Description

technical field [0001] The invention belongs to the field of mica board preparation, and in particular relates to a method for improving the appearance chromaticity of a synthetic mica board. Background technique [0002] At present, after the synthetic mica board is pressed at high temperature, there are problems such as yellowing at the edge and excessive impurities, which not only affects the use of customers, but the yellowing of the edge of the mica board also leads to poor light transmission after assembly. Therefore, there is an urgent need for a method for improving the appearance chroma of the synthetic mica board to meet the needs of high-end customers. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the above-mentioned prior art and provide a method for improving the appearance chromaticity of the synthetic mica board, using mica material and organic silica gel water as the main materials for preparation...
