Problems solved by technology

The products produced by this method have the characteristics of precise size and easy control of tolerances, but the production efficiency of this method is low, and the requirements for process equipment (such as spraying equipment) are high, and the input cost of process equipment is high, so the production cost is increased. ;The size of the product board is single and the thickness range is narrow, so it is not possible to produce products with higher thickness

Abstract

The invention discloses an unsaturated polyester glass fiber mat board which is obtained by pressing the glass fiber mat immersed with resin paste. The production method thereof comprises: after being stirred evenly, the resin paste is scraped and smeared on a polyethylene film evenly; later a layer of polyethylene film is respectively paved on the upper surface and the lower surface of the glass fiber mat, then a sizing mat is obtained after tight pressing; when the sizing mat is cured, the polyethylene films on the surfaces of the mat are removed; next, the sizing mat is delivered into a press for hot pressing at the temperature of 70 DEG C-145 DEG C and the pressure of 10-20MPa; according to the thickness of the eventually obtained mat board, the mat board with the thickness of each millimeter is hot-pressed for 3-15 minutes; and finally an unsaturated polyester glass fiber mat board is obtained. The unsaturated polyester glass fiber mat board has excellent flame resistance, insulation, electrical and mechanical properties. The production method of the unsaturated polyester glass fiber mat board improves the productivity, reduces the production cost, and can prepare board surfaces with various sizes; and the thickness of the product has large range.

Description

technical field [0001] The invention relates to a glass fiber mat, in particular to an unsaturated polyester glass fiber mat and a production method thereof. Background technique [0002] Unsaturated polyester fiberglass mat has the characteristics of good flame retardancy, good performance and excellent machinability, so it is widely used as insulating structural parts in motors and electrical equipment. At present, it is mainly prepared by molding processes such as pultrusion molding, resin transfer molding molding, and compression molding. In order to improve the electrical properties and flame retardant properties of unsaturated polyester fiberglass mat, a large amount of aluminum hydroxide filler can be added to the unsaturated polyester resin (this filler has good electrical properties, and belongs to the halogen-free green resistance Combustible materials), the resulting resin paste has a high viscosity, so it is not suitable for pultrusion and resin transfer molding...
