Kieselguhr modified fiber enhanced PVC floor base material and production process thereof

Abstract

The invention discloses a kieselguhr modified fiber enhanced PVC floor base material and a production process thereof, and belongs to the technical field of new materials. A carbon fiber waste filament, a basalt fiber waste filament, and / or a glass fiber waste filament is used as an additive, and second-level kieselguhr and / or third-level kieselguhr is used as a modifier, so that the floor base material with a three-layer structure is formed by adopting a co-extrusion production process; an upper epidermal layer and a lower epidermal layer are made of kieselguhr modified fiber enhanced PVC composite materials prepared from the fiber additive and the second-level kieselguhr and / or third-level kieselguhr serving as the modifier, and a middle layer is made of a kieselguhr modified fiber enhanced PVC composite material; kieselguhr is the second-level kieselguhr and / or the third-level kieselguhr; therefore, the problems on thermal stability and illumination stability of a common PVC floor are effectively solved; the weight of a floor is substantially reduced; the stability of the floor is further improved, and the machining strength and the aging resistance of the floor are improved; the kieselguhr modified fiber enhanced PVC floor base material further has the functions of adsorbing formaldehyde and peculiar smell, removing odor and adsorbing harmful pollutants.

Description

technical field [0001] The invention belongs to the technical field of new materials, and relates to a diatomite-modified fiber-reinforced PVC floor base material and a production process thereof. Background technique [0002] Along with the increasing shortage of domestic and foreign timber markets, various new types of floors that replace timber emerge in an endless stream. At present, various floorings with PVC as the main raw material have become mainstream products in the domestic and foreign markets. However, ordinary PVC plastic floors have serious deformation problems, especially long-term sunlight or geothermal temperature, which will cause deformation of plastic floors. . The deformation of the wood-plastic floor is slightly better, but there is still a deformation problem. The deformation of the stone-plastic floor is relatively small, but the weight of the floor per unit area increases. At the same time, the floor has a poor sense of solid wood and poor elastic...
