Nanoceramics-reinforced high-precision PVC-NBR composite foaming board and preparation method thereof

Abstract

The invention discloses a high-precision PVC‑NBR composite foam board reinforced by nano-ceramic. Improve the dimensional accuracy of the composite board and prevent the board from being deformed by heat. The added nano-ceramic powder is modified by a silane coupling agent to better disperse and bind, and the effect of strengthening and toughening is remarkable, which effectively improves the heat resistance and flame retardancy of the composite board. , more safe and reliable, the composite foam board finally prepared by the present invention has outstanding advantages in terms of thermal stability, flame retardant safety, environmental protection, shape stability, etc., and has a good application prospect.

Description

technical field [0001] The invention relates to the technical field of PVC foam boards, in particular to a nano-ceramic reinforced high-precision PVC-NBR composite foam board and a preparation method thereof. Background technique [0002] PVC foam board has the characteristics of waterproof, flame retardant, acid and alkali resistance, moth resistance, light weight, heat preservation, sound insulation, shock absorption, etc. It is an ideal substitute for wood, aluminum and composite boards, and is widely used in passenger cars and train carriages Ceiling, box core layer, interior decoration panels, building exterior wall panels, interior decoration panels, office, residential, public building compartments, commercial decorative frames, clean room panels, ceiling panels, etc. [0003] Although PVC foam board has such a wide application space, its actual market share is low, especially in terms of home decoration materials.

Problems solved by technology

[0003] Although PVC foam board has such a wide application space, its actual market share is low, especially in terms of home decoration materials. Satisfactory, there are potential safety hazards when using. In order to improve the comprehensive performance of PVC sheets, the most common method is to use polymer materials and inorganic fillers for blending modification.

In the article "Research on Flame Retardant NBR / PVC Foaming Materials", NBR and PVC are blended and foamed to obtain products with relatively good mechanical properties, but their heat resistance is poor, and flame retardants need to be added to achieve flame retardant effects, but for The mechanical properties of the material are greatly affected, and the use is limited
