Abstract
The invention discloses a wind driven generator blade adhering method. The key point of the technical scheme is that: the method comprises the following steps of: respectively manufacturing a pressure bearing surface body and a negative pressure surface body of a wind driven generator blade; pretreating adhering surfaces of the pressure bearing surface body and the negative pressure surface body of the wind driven generator blade by using a polyisocyanate material; and adhering the pretreated pressure bearing surface body and negative pressure surface body by using an epoxy resin structural adhesive. The invention aims to overcome the defects of the prior art, and provides a wind driven generator blade adhering method which has the advantages of firm adhesion, simple operation and low production cost.
Description
[technical field]
The present invention relates to a kind of blade of wind-driven generator adhering method.
[background technology]
Wind energy is a kind of green energy resource, in order more effectively to utilize wind energy, needs to use Large-scale Wind Turbines to convert wind energy to electric energy.Key components and parts as Large-scale Wind Turbines---blade all adopts fiber reinforced epoxy resin to make.The adhering method of the blade of present most Large-scale Wind Turbines is: make earlier the pressure-bearing surface and the suction surface of blade respectively, and then bonding with epoxy resin structural adhesive.When bonding,, there are not energy and epoxy resin reactive activity group on the bonding plane substantially because sufficient chemical reaction has taken place for the pressure-bearing surface and the suction surface of blade.Also just caused between structure glue and the blade bonding plane and can not form the chemical bond connection, the bonding force that equals structure glue-line and blade shell surface is mainly realized by intermolecular active force Van der Waals force.And Van der Waals force is often much lower than the power of chemical bond, so bonding plane has also just become the weakest position of blade.In long-term use, it is exactly that blade uses the back cracking to occur for a long time that this bonding problem of bringing shows.
[summary of the invention]
The present invention seeks to have overcome the deficiencies in the prior art, provide a kind of bonding firm, simple to operate, the blade of wind-driven generator adhering method that production cost is low.
The present invention is achieved by the following technical solutions:
A kind of blade of wind-driven generator adhering method, it is characterized in that: the pressure-bearing surface body 101 and the suction surface body 102 that comprise the steps: to make respectively earlier blade of wind-driven generator 1, then to the bonding plane of the pressure-bearing surface body 101 of blade of wind-driven generator 1 and suction surface body 102 with the preliminary treatment of polyisocyanic acid ester material, it will be bonding to pass through epoxy resin structural adhesive through pretreated pressure-bearing surface 101 and suction surface 102 more at last.
Aforesaid blade of wind-driven generator adhering method is characterized in that: described polyisocyanic acid ester material is active polyisocyanates.
Aforesaid blade of wind-driven generator adhering method is characterized in that: described polyisocyanic acid ester material is a polyisocyanate solution.
Compared with prior art, the present invention has following advantage:
Blade of wind-driven generator adhering method of the present invention is simple to operate, and production cost is low, and is bonding firm.

[specific embodiment]
A kind of blade of wind-driven generator adhering method, comprise the steps: to make respectively earlier the pressure-bearing surface body 101 and the suction surface body 102 of blade of wind-driven generator 1, then to the bonding plane of the pressure-bearing surface body 101 of blade of wind-driven generator 1 and suction surface body 102 with the preliminary treatment of polyisocyanic acid ester material, it will be bonding to pass through epoxy resin structural adhesive through pretreated pressure-bearing surface body 101 and suction surface body 102 more at last.
Described polyisocyanic acid ester material is active polyisocyanates or polyisocyanate solution.
Oh group elder generation and polyisocyanates generation chemical reaction on the blade of wind-driven generator bonding plane form a large amount of chemical bonds, and leave unnecessary isocyanate groups on bonding planes.Unnecessary then isocyanate reactive group and epoxy resin structural adhesive generation chemical reaction.Thereby make blade shell all form a large amount of chemical bonds, improve the adhesive strength of blade pressure-bearing surface and suction surface significantly, thoroughly solve the bonding problem of blade to structure glue.
