Problems solved by technology

However, under the high-temperature baking condition exceeding 350°C, because the epoxy resin will be cracked in this high-temperature environment, when epoxy resin is used as the edge banding agent, both sides of the edge banding cloth will be detached, so the existing conventional edge banding Cloth cannot be used in high temperature baking conditions, which limits the application of edge banding cloth in high temperature impregnation industry

Abstract

The invention provides a high-temperature-resistant glass fiber cloth edge sealing agent. According to the total mass percent of 100%, the water-based paint comprises the following raw material components: 40%-90% of fluorine resin, 1%-3% of a surfactant, 1%-3% of a silane coupling agent and 4%-58% of water. The invention further provides a preparation method of the high-temperature-resistant glass fiber cloth edge sealing agent. The preparation method comprises the following steps: mixing a silane coupling agent with water to obtain a first mixture; mixing fluorine resin with a surfactant to obtain a second mixture; and mixing the first mixture and the second mixture to obtain the high-temperature-resistant glass fiber cloth edge sealing agent. The high-temperature-resistant glass fiber cloth edge sealing agent prepared by the invention can meet a higher-temperature baking condition, the edge sealing agent material is not easy to crack under the condition of high-temperature baking, and the problem that two sides of the edge sealing cloth fall off under the condition of high-temperature baking can be effectively solved.

Description

technical field [0001] The disclosure relates to the field of material technology, in particular to a high-temperature resistant glass fiber cloth edge sealing agent and a preparation method thereof. Background technique [0002] Glass fiber cloth is used in the impregnation industry, and glass fiber cloth can be divided into feather edge cloth and edge banding cloth according to whether it contains feather edge. The feather edge fabric will take away more glue during the gluing process on the downstream copper clad board, resulting in waste, and the feather edge fabric will break when it is processed by the extrusion wheel during the production process because it has no force to bind, and the electronic parts of the broken part Grade glass fiber strands falling into the impregnation tank will contaminate the glue. [0003] In the prior art, edge banding cloth is used instead of feather edge cloth to reduce the scrapping of glue used for impregnation and the generation of c...
