Description
Technical Field
The invention relates to the technical field of wind power blade manufacturing, in particular to a light-cured resin for wind power, and further provides a preparation method of the light-cured resin for wind power.
Background
A resin system mainly used for wind power generation is epoxy resin, in order to meet the design requirement of a large-size blade, a conventional wind power blade manufacturer uses a carbon fiber and glass fiber pultrusion plate to replace a traditionally used glass fiber unidirectional fabric, and the excellent performance of the pultrusion plate is generally accepted by wind power blade manufacturing enterprises. The production of pultruded panels with epoxy resins is currently used in many applications, however, the production speed is far slower than that of unsaturated polyesters, which contain styrene, which can cause serious environmental pollution.
The existing light-cured resin in the existing market is not provided with a corresponding product for blade adhesion in the field of wind power, and the existing light-cured resin only considers static mechanical properties but not fatigue properties after being combined with glass fibers, so that the existing light-cured resin cannot be applied to wind power blades.
At present, a plurality of wind power blade manufacturing enterprises have blade design tests for replacing traditional glass fiber unidirectional fabrics with glass fiber pultruded panels, however, the reason that the market is pushed slowly at present is that the cost of the glass fiber pultruded panels is too high, and the main reason is that the production cost of products is high due to the low production speed of epoxy system pultruded resin in the production process, so that the price of the products exceeds the design requirements of the blade enterprises. In response to this phenomenon, there is a great need for an alternative system of resin to replace the existing pultruded resins of epoxy systems, thereby increasing the production efficiency of pultruded panels of glass fibers.
In the current fiber and resin combined composite material industry, no matter prepreg molding or wet resin molding, the future ideal development direction is the rapid curing cost and the rapid batch production process, based on the consideration of the factors, the existing rapid molding resin curing methods such as UV (ultraviolet curing) and EB (electron beam curing) are comprehensively analyzed, and because EB curing equipment is expensive and the difficulty of developing molding equipment in a matching way, the existing market is mainly UV curing, and the market application is the widest due to the flexible and various curing methods.
