Abstract

The invention discloses an inflaming retarding wave absorbing type carbon fiber composite wood board. The inflaming retarding wave absorbing type carbon fiber composite wood board is a plate layer structure body of a split structure. The inflaming retarding wave absorbing type carbon fiber composite wood board is formed in the manner that alkaline liquid immersing pretreatment is conducted on an ordinary wood board I, a hard wood board and an ordinary wood board II, inflaming retarding agent treatment and drying are conducted, pressing connection of the ordinary wood board I and a polyimide layer through a first wood glue layer, pressing connection of the polyimide layer and a carbon fiber layer through a first inflaming retarding wave absorbing bonding layer and pressing connection of the carbon fiber layer and the hard wood board through a second inflaming retarding wave absorbing bonding layer are sequentially conducted, and the hard wood board is in pressing connection with the ordinary wood board II through a second wood glue layer. The composite wood board retards inflaming and absorbs waves, the oxygen index reaches 42-48, the parallel-to-grain compressive strength is larger than 100 MPa, the anti-bending strength is larger than 200 MPa, the lead equivalent value is larger than 0.012 Pb / mm, infrared, X, alpha, beta rays and other electromagnetic waves can be effectively absorbed, and the anti-radiation performance is high. The invention further discloses a manufacturing method for the inflaming retarding wave absorbing type carbon fiber composite wood board.

Description

technical field [0001] The invention relates to a composite wood board, in particular to a flame-retardant and wave-absorbing carbon fiber composite wood board and a manufacturing method thereof. Background technique [0002] Wood is composed of 90% cellulose, hemicellulose, lignin, water and 10% extract and ash. The basis is also the basis for wood modification and flame retardant and wave-absorbing treatment. [0003] With the development of science and technology, microwave-absorbing materials have special uses, especially in the military field, and play an important role. There is less electromagnetic radiation, which is harmful to human health, and the absorbing material can effectively absorb various harmful rays to the human body. As one of the four main materials, wood has a wide range of applications in the coating industry. Combined with certain processes, it can be converted into a wave-absorbing material (adding polyimide, carbon fiber and wave-absorbing adhesi...
