Embodiment Construction

[0021] In order to make the above objects, features and advantages of the present invention more clearly understood, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0022] This embodiment provides a method for reusing waste wind power blades, such as figure 1 shown, including:

[0023] S102 , mixing the waste wind power blade material within a preset size range with the thermoplastic material to obtain a molding compound.

[0024] Specifically, in this embodiment, when kneading, the prepared waste wind power blade material can be fluffed and fully kneaded with thermoplastic resin glue in an internal mixer until the resin is completely mixed, and then dried or dried to Appropriate viscosity to obtain the desired molding compound. Among t...

Abstract

The invention provides a waste wind power blade recycling method, and relates to the field of waste wind power blade recycling. The method comprises the following steps: mixing a waste wind power blade material and a thermoplastic material in a preset size range to obtain a molded material; and carrying out compression molding on the molded material to obtain a wind power matching product. According to the method, solid waste can be greatly reduced, so that the problem of ecological environment pollution caused by the waste wind power blade is solved, the waste wind power blade is manufactured into the blade root platform or the manhole cover plate in a compression molding mode, and the service life of the blade root platform or the manhole cover plate is prolonged. The residual mechanical property and value of the waste wind power blade made of the glass fiber composite material can be fully utilized, and recycling and high-value reutilization of the waste wind power blade are achieved. Besides, compared with a traditional blade root platform and manhole cover plate manufacturing method, the blade root platform, the manhole cover plate and other wind power matching products manufactured through the method are mostly made of waste wind power blade materials, and therefore the raw material cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of reuse of waste wind power blades, in particular to a method for recycling waste wind power blades. Background technique [0002] In the prior art, glass fiber reinforced epoxy resin is usually used as the raw material for wind turbine blades, which is a thermosetting composite material. After curing and molding, the original properties of the material cannot be restored, so it cannot be degraded. a huge threat. Traditional burial and burning treatment occupy a lot of land resources, cause serious groundwater and air pollution, and do not give full play to the residual mechanical properties and value of glass fiber composites. In the face of a large number of decommissioned blades in the future, the recycling and high-value reuse of them has become a problem that the industry is generally concerned about. Therefore, it is of great significance to develop a low-cost, high-efficiency regeneration method fo...
