Abstract
The invention discloses an epoxy resin system for manufacturing a blade mould of a wind-driven generator and a preparation method thereof. The epoxy resin system consists of a resin part and a curing agent part. The epoxy resin system is characterized in that the curing agent part comprises the following components in parts by weight: 20-50 parts of polyetheramine, 30-50 parts of isophorone diamine, and 20-40 parts of 4,4'-diaminodicyclohexylmethane and derivatives thereof; and the epoxy resin system is formed by mixing the resin part and the curing agent part in weight ratio of 100 parts to 20-40 parts. The glass-transition temperature of a condensate of the epoxy resin system is 90-150 DEG C; the blade mould of the wind-driven generator, which is prepared by the epoxy resin system, has very high glass-transition temperature and mechanical property, which can meet the production requirements of the blade mould of the wind-driven generator, especially the blade mould of the wind-driven generator at more than megawatts level; in addition, the economic effect of the epoxy resin system is remarkable.
Description
Technical field
The present invention relates to the preparation method of epoxy-resin systems and this epoxy-resin systems, specifically is a kind of epoxy-resin systems of making by the blade of wind-driven generator mould and preparation method thereof that is used to.With the product that this epoxy-resin systems and method make, be particularly suitable for hand paste technology and vacuum perfusion process that the above blade of wind-driven generator mould of MW class is made, satisfy the application requiring of the above used for blades of wind driven generator resin mould of MW class system.
Background technology
Epoxy-resin systems is widely used in industries such as wind-powered electricity generation, building, high ferro and electronics, along with the extensive and development of the national economy of sustainable development of China, China increases rapidly to the demand of epoxy-resin systems, has caused the concern of international and domestic Resins, epoxy industry height.Large-scale factory is built in almost all come or the coming China investment of Resins, epoxy transnational company in the world, and domestic enterprise is also newly-built one after another, enlarging Resins, epoxy production equipment, and therefore, China's epoxy-resin systems is just entering a new crucial evolution period at present.
However, the epoxy-resin systems of China's independent research still lacks high-end product, especially for the epoxy-resin systems of making the blade of wind-driven generator mould, this is wherein especially more outstanding with epoxy-resin systems with the blade of wind-driven generator mould more than the MW class.Because the epoxy-resin systems of used for blades of wind driven generator needs heating so that its completion of cure in solidification process, and a large amount of heat releases of meeting when solidifying, thermotolerance requirement to its mould is quite high, and the second-order transition temperature of the epoxy-resin systems cured article of its mould of general requirement needs more than 90 ℃.If its second-order transition temperature is lower, the a large amount of heat releases when solidifying of the Resins, epoxy of used for blades of wind driven generator, die temperature can be heated on its second-order transition temperature, mould will be the viscoelastic attitude by glassy transition, shape changes, cause this mould to be scrapped, and can cause prepared blade of wind-driven generator can not satisfy the shape need of its design; Simultaneously, because the weight of every blade is several tons usually, also quite high to the mechanical property requirements of mould.In order to improve the research and development throughput of China's epoxy-resin systems, grasp core technology, each epoxy-resin systems manufacturing enterprise and institute are also in unremitting effort.
In recent years,, on various public publications, also saw relevant report repeatly, but do not see the correlation technique report of the epoxy-resin systems of suitable wind-powered blade mold so far with high glass-transition temperature about various researchs to epoxy-resin systems.For a long time, external relevant major company externally is kept absolutely secret to the prescription and the preparation technology of high-end epoxy-resin systems, monopolized by the major company that abroad is correlated with especially for making the epoxy-resin systems of producing the blade of wind-driven generator mould always, make China's wind-powered electricity generation industry have to rely on these major companies, the cost fancy price satisfies the epoxy-resin systems of production requirement from these major company's imports.Nonetheless, the supply chain of import epoxy-resin systems also quite is critical, and this has influenced the ordinary production and the profit level of domestic enterprise to a great extent, thus the development of influence and restriction China wind-powered electricity generation industry.
In sum, research and develop that a kind of can to satisfy the epoxy-resin systems that is used to make the blade of wind-driven generator mould particularly important, not only can break the blockade on new techniques of Overseas Company, early the epoxy-resin systems high-end product is realized production domesticization, reduce the production cost of domestic epoxy-resin systems industrial chain, particularly the production cost of wind-powered electricity generation industry is benefited the people's livelihood; And can effectively promote the competitive power of China's wind-powered electricity generation industry in the world market, and make China wind-powered electricity generation industry realize great powers in the world, go forward side by side and become power.
