Abstract

The invention discloses a latent epoxy resin system for wind-driven generator blades. The latent epoxy resin system is formed by combining a resin part and a curing agent part, wherein the resin part comprises bisphenol A epoxy resin and a diluent; and the curing agent part comprises a polyether amine compound, an alicyclic amine compound and an organic guanidine compound. The preparation method comprises the following steps of: (1) preparing materials in a ratio of the resin part to the curing agent part respectively and preparing mixing equipment; (2) preparing the resin part and the curing agent part respectively; and (3) preparing the latent epoxy resin system and mixing the prepared resin part and the prepared curing agent part in the ratio uniformly. The latent epoxy resin system has the characteristics of flexible gelation time, low requirement of the operating environment on the temperature, high operability and the like, the operability of the epoxy resin system is greatly improved when the epoxy resin system is applied to a blade vacuum perfusion process, the production efficiency and qualification rate of the blades are improved, and the production cost of enterprises is reduced.

Description

technical field

[0001] The invention relates to an epoxy resin system, in particular to a latent epoxy resin system for wind generator blades, and a preparation method of the epoxy resin system. The epoxy resin system of the present invention is particularly suitable for the vacuum infusion process application in the manufacture of high-power wind power generator blades. Background technique

[0002] As we all know, the key to obtain greater wind power is to have blades that can rotate briskly. Therefore, the blade is the core of the wind turbine, and the performance of the blade material is the key to determine the performance of the wind turbine. For a long time, the key technologies and materials of my country's wind power generation industry have been controlled by foreign countries, especially the resin system used in the production of blades, which makes my country's wind power generation companies have to rely on related large foreign companies to spend high prices f...
