Embodiment 1

[0068] Example 1: Assuming that the surfactant and the acid solution were exposed to carbon fiber reinforced plastics under a vaporized atmosphere, waste CFRP was not impregnated in the acid solution in advance, but was dripped around the CFRP (100 parts by mass). Add mixed solution a (12.58% of mixed solution a obtained by adding 0.64 mass parts of surfactant relative to acid solution a of 100 mass parts) made of surfactant (0.08 mass parts) and acid solution a (12.5 mass parts) parts by mass), and heated at the same time.

Embodiment 2

[0069] Example 2: Assuming the conditions of immersing carbon fiber reinforced plastics in a surfactant and an acid solution and then burning them, waste CFRP was previously immersed in a solution obtained by adding 0.64 parts by mass of surfactant to 100 parts by mass of acid solution a. After mixing solution a, heat the dehydrated waste CFRP. (The mixed liquid a adhering to the spent CFRP during heating is 13.5 parts by mass relative to 100 parts by mass of this CFRP).

Embodiment 3

[0070] Embodiment 3: except changing acid solution a into acid solution b, all the other conditions are the same as embodiment 1.

Abstract

Provided is a method for processing carbon fiber-reinforced plastic whereby carbon fiber-reinforced plastic can be sufficiently burned using less effort. Carbon fiber-reinforced plastic is placed in contact with a surfactant and an acid solution, then incinerated.

Description

technical field [0001] The present invention relates to a method of incinerating waste plastics containing carbon fibers and treating them. Background technique [0002] In recent years, demand for composite materials composed of matrix materials such as resins and metals and carbon compounds has increased dramatically as lightweight and high-strength structural materials. In particular, demand for carbon fiber-reinforced plastics (CFRP: Carbon Fiber reinforced plastics) obtained by combining a matrix material composed of a thermosetting resin or a thermoplastic resin and carbon fibers has increased significantly. On the other hand, as the demand increases, the amount of waste containing carbon fiber-reinforced plastics also increases. [0003] As a treatment method for such carbon fiber reinforced plastics, there is a method of effectively utilizing them as an alternative fuel in the cement manufacturing process and incinerating them. [0004] However, when carbon fiber-r...
