Abstract

The invention relates to a nonsaturated polyester fibrofelt plate and its production method. The nonsaturated polyester glass fibrofelt molded plate is formed by superposing and moulding three layers of an upper superficial layer, a lower superficial layer and an interface layer, wherein the upper and lower superficial layers respectively contain one or more materials selected from glass fiber continuous stand mat, glass fiber continuous monofilament mat and glass fiber surface mat; and the interface layer contains one or more layers of a glass fiber mat prepreg obtained by dipping glass fiber chopped strand mat or glass fiber continuous stand mat into a resin paste. The nonsaturated polyester glass fiber molded plate provided by the invention has advantages of excellent electrical isolation performance and corrosion resistance, especially high electrical isolation performance in harsh environments such as the hot and humid environment, high flame retardance, no toxic effect of gases generated from the combustion of the product, environmental protection with no pollution, high mechanical strength and long service life.

Description

technical field [0001] The invention relates to a glass fiber felt, in particular to an unsaturated polyester fiber felt board and a production method thereof. Background technique [0002] Unsaturated polyester fiberglass felt molded board has corrosion resistance, high electrical insulation, high flame retardancy, good mechanical strength, easy processing, halogen-free and environmentally friendly, and the gas produced by combustion is non-toxic, making this composite material widely used in electrical appliances. , Various high-performance insulating parts. [0003] At this stage, this type of plate is mainly prepared by pultrusion and lamination processes, but not by compression molding. [0004] The pultrusion molding process starts from the input of raw materials, through the processes of dipping, forming, curing, demoulding, cutting, etc., until the final product is obtained. The entire process is carried out continuously. However, the products manufactured by it ar...
