Embodiment Construction

[0018] The present invention will be further described below in conjunction with the examples.

[0019] In the present invention, each component and source are respectively:

[0020] The two-component polyurethane resin is selected from: two-component polyurethane resin SK 97007, purchased from Huntsman Chemical R&D Center (Shanghai) Co., Ltd.; or two-component polyurethane resin CC6226 / 101C-A, purchased from BASF Polyurethane Specialty Products (China ) Ltd. The same type of domestic two-component polyurethane resin can also be used.

[0021] Two-component polyurethane resin special flame retardants are selected from: reactive flame retardant Flame Check X6667, additive flame retardant Flame Check 2725, additive flame retardant Flame Check 2750, all purchased from American Reves Corporation.

[0022] A batch of glass fiber-reinforced two-component polyurethane material was prepared, and the formula was as follows:

[0023]

[0024] Its preparation method includes the fo...

Abstract

The invention provides a glass fiber-reinforced bi-component pultruded polyurethane resin material which is at least prepared from the following components: alkali-free glass fiber yarn, glass fiber fabrics, bi-component polyurethane resin, a special flame retardant agent for bi-component polyurethane resin and color paste. The polyurethane material is rich in source of raw materials and low in preparation cost; a magnetic steel batten of a direct-driven permanent magnetic synchronous wind turbine prepared from the polyurethane material is flat and smooth in surface, free of bubbles and exposed fibers, unlikely to be contaminated by oil, uniform in surface color, and unlikely to have cracks, delaminate and produce mechanical scars.

Description

technical field [0001] The invention belongs to the field of power generation equipment, in particular to a glass fiber-reinforced two-component pultruded polyurethane material, and also relates to the application of the material to the magnetic steel layer of a direct-drive permanent magnet synchronous wind power generator. Background technique [0002] In nature, wind energy is a renewable, non-polluting, and clean energy with huge reserves, which has attracted widespread attention from all over the world. The development and utilization of wind energy, especially the vigorous development of wind power, has accelerated the research and development of wind turbines. In recent years, according to the official report of the Global Wind Energy Council, the installed capacity of wind turbines in various countries has continued to rise, and its proportion in the power grids of various countries is also increasing. Therefore, ensuring the safe and stable operation of wind turbin...
