Abstract

The invention discloses an environment-friendly preparation technology for a composite material. The environment-friendly preparation technology comprises the following steps: preparing a mould; preparing a gel coat layer; performing leakage-proof shaping on the mould; assembling the mould; paving a reinforcing rib and a reinforcing layer; paving vacuum accessories and a runner; packaging a vacuumfilm; introducing a resin in vacuum; curing and recycling styrene; de-molding; cutting and shaping; recycling slitter edges and dust. When styrene is recycled, styrene is under gaseous state; a fin tubular type styrene condenser is adopted for recycling styrene; desalted water is used as a cooling medium; the recycled styrene material is served as a resin material introduced in vacuum. Accordingto the invention, the manner of condensation recycling is adopted for solving the problem of serious benzene and alkene pollution of the prior art. The recycled styrene is used as the resin material again, so that the pollution is reduced and the cost is greatly lowered.

Description

technical field [0001] The invention belongs to the technical field of glass fiber reinforced plastics, and in particular relates to an environment-friendly preparation process of composite materials. Background technique [0002] With the rapid development of science and technology and the continuous adoption of new materials and technologies, a large number of new composite materials with light weight and high strength have been widely used in the design, manufacture and use of various products, and have achieved remarkable benefits, such as wind turbines.
