Abstract
The invention relates to the technical field of decorative plates, in particular to a PVC (polyvinyl chloride) foaming plate containing carbon fiber yarns and a production process thereof.
Description
Technical Field
The invention relates to the technical field of decorative plates, in particular to a PVC foaming plate containing carbon fiber yarns and a production process thereof.
Background
The PVC foaming board takes polyvinyl chloride as a raw material, and other auxiliary agents are added to increase the performances of heat resistance, ductility and the like, has the characteristics of water resistance, convenient construction and the like, is widely applied to the fields of buildings, furniture and the like, and is an ideal substitute for wood, aluminum materials and composite boards.
The patent document with the application number 202210627401. X discloses a processing technology for producing a PVC foaming board by utilizing waste materials, wherein special materials, filling agents (calcium carbonate), environment-friendly stabilizers, plasticizers, AC foaming agents, NC foaming agents, internal lubricants, external lubricants, foaming regulators, odor removing agents, antioxidants and other raw material mixtures are prepared from recycled PVC label paper, and then the PVC foaming board is obtained by heating and plasticizing, pressurizing a plasticized melt, expanding the pressurized melt extrusion die, cooling and shaping the molded melt extrusion die, pulling a substrate, cutting edges according to width requirements and transecting the board according to length requirements.
The PVC foaming plate has insufficient hardness and tensile strength, limits the application scene, and increases the thickness of the plate and the use cost of customers when the requirement on the bearing capacity of the material is high.
Disclosure of Invention
The invention aims to solve the technical problem of providing a PVC foaming plate containing carbon fiber yarns and a production process thereof.
