Description

Flame-retardant anti-static composite material plate and preparation method thereof
Technical Field
The invention relates to a flame-retardant antistatic composite material plate and a preparation method thereof, which can be used for manufacturing flame-retardant antistatic floors, partition boards, wall boards and the like in places such as machine rooms, storehouses, factory buildings and the like, and belongs to the technical field of composite materials.
Background
In some special places such as machine rooms, storehouses, factory buildings and the like, the used floors, partition boards, wall boards and the like are often required to have flame retardant and antistatic effects so as to prevent fire or explosion caused by sparks generated by static electricity and prevent fire and the like caused by sparks generated in the operation process. Conventionally, in order to eliminate static electricity, an antistatic agent may be added to the material; in order to achieve the flame retardant effect, a non-combustible material such as a metal material, a ceramic material and the like can be selected, or a combustible material is selected, and a flame retardant is added into the combustible material to achieve the flame retardant effect. These traditional methods all have certain limitations, and often cannot solve the problems of static electricity prevention and flame retardance at the same time. In addition, the metal material and the ceramic material are heavy and inconvenient to transport and install.
The polymer-based composite material is a novel material obtained by compounding a polymer serving as a matrix and fibers serving as a reinforcement through a certain process, has the characteristics of light weight, high specific strength, convenience in molding and processing, corrosion resistance and the like, and is widely applied to the fields of petroleum, chemical industry, building, transportation and the like at present. However, the traditional polymer matrix composite material does not have an antistatic effect and is not flame-retardant, so that great potential safety hazards exist in places such as special machine rooms, storehouses and factory buildings.
In order to overcome the defects and further play the role of the polymer matrix composite, the invention of the flame-retardant antistatic composite plate is necessary.
