Green recycled carbon fiber thermoplastic material building board and preparation method

Abstract

The invention discloses a building board made of green recycled carbon fiber thermoplastic material, which includes a carbon fiber felt and a thermoplastic resin layer. The front and back sides of the carbon fiber felt are provided with transverse grooves, longitudinal grooves and vertical holes. Horizontal holes parallel to the front of the carbon fiber felt are opened on the facade, and the thermoplastic resin layer is heat-pressed on the front and back of the carbon fiber felt by a hot press. In the present invention, uniform transverse grooves, longitudinal grooves and vertical holes are pressed out on the front and back of the carbon fiber felt, which not only increases the effective bonding area between the carbon fiber felt and the thermoplastic resin layer, but also makes the carbon fiber felt and the thermoplastic resin layer form unevenness Combined structure, so as to improve the bonding strength between the thermoplastic resin layer and the carbon fiber felt; the thermoplastic resin powder in the vertical hole can be melted during hot pressing, so that the thermoplastic resin layer on the front and back of the carbon fiber felt is integrated with the thermoplastic resin in the vertical hole Thermoforming.

Description

technical field [0001] The invention relates to the technical field of building boards. Specifically, it is a green regenerated carbon fiber thermoplastic material building board and a preparation method. Background technique [0002] Traditional building boards are generally wood or metal boards. The use of wood boards consumes a lot of wood, and the use cycle is short, the quality of metal boards is large, and the transportation and cutting are difficult. In order to solve the inconvenience of using traditional boards, The technology of using recycled carbon fiber to process and manufacture building boards came into being. It has high strength and light weight, which is easy to transport and process. However, after recycled carbon fiber is made into carbon fiber felt, its surface has poor adhesion to thermoplastic resins. , After hot pressing, the bonding strength between the resin layer and the carbon fiber felt is insufficient, and the resin layer and the carbon fiber f...

AI Technical Summary

Problems solved by technology

[0002] Traditional building boards are generally wooden boards or metal boards. The use of wooden boards consumes a lot of wood, and the service life is short. The metal boards are of high quality and difficult to transfer and cut. In order to solve the inconvenience of using traditional boards, The technology of using recycled carbon fiber to process and manufacture building panels has emerged at the historic moment. It has high strength and light weight, which is convenient for transportation and processing. However, after the recycled carbon fiber is made into carbon fiber felt, its surface has poor adhesion to thermoplastic resin. After hot pressing, the bonding strength between the resin layer and the carbon fiber felt is insufficient, and the resin layer and the carbon fiber felt are prone to peeling and delamination, which will affect the use of the board
