Abstract

The invention provides a TPU (thermoplastic polyurethane) composite membrane used for fan blades and a preparation method for the TPU composite membrane. The TPU composite membrane is prepared from the following raw materials in parts by weight: 70 to 90 parts of TPU particles, 10 to 25 parts of glass fiber reinforced polybutylene terephthalate, 2 to 10 parts of PVDF (polyvinylidene fluoride), 3 to 8 parts of compatilizer, 1 to 5 parts of pore-foaming agent, 1 to 3 parts of antioxygen and 0.5 to 1 parts of ultraviolet light absorber. The TPU composite membrane provided by the invention is high in strength (the tensile strength can reach 85.1mpa) and high in heat resistance (the maximum vicat softening temperature is 128 DEG C), has good heat insulation property (the minimum heat conductivity coefficient is 0.012w / (m.k)), and is not is easy to separate from adhesive; when the TPU composite membrane is used for the fan blades, the fan blades can be protected to prolong the service life of the fan blades; moreover, the preparation method for the TPU composite membrane is simple.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a TPU composite film for fan blades and a preparation method thereof. Background technique [0002] In today's global background of increasing shortage of non-renewable energy, rapid climate change, and deteriorating environment, wind energy, as a renewable and green energy source, has attracted great attention from all countries. productive forces. According to the calculation that the cost of blades accounts for 1 / 4 of the cost of the total machine, the domestic market size of China's wind turbine blades will exceed 50 billion yuan in the next 15 years. The "Eleventh Five-Year Plan" clearly stated that the localization rate of wind power equipment such as fan blades in newly-built wind farms must reach more than 70%. Domestic wind power heat. [0003] During the working process of the fan, the fan blades are subjected to external effects such as strong ...
