Nano-cellulose toughened high heat resistant PVC-NBR composite foam board and preparation method thereof

Abstract

The invention discloses a nano-cellulose toughened high heat resistant PVC-NBR composite foam board and a preparation method thereof. As a PVC and NBR blending material is used as a composite board base material of the nano-cellulose toughened high heat resistant PVC-NBR composite foam board and high heat resistant polyimide porous micro spheres are added to the nano-cellulose toughened high heat resistant PVC-NBR composite foam board, the heat resistance of the composite board is greatly improved; as the added nano-cellulose has better compatibility with resin after being modified by silane coupling agent, the toughening effect is obviously enhanced and the biodegradability of the board is enhanced, so that the board is environmentally friendly; the finally prepared composite foam board is heat resistant, flame retardant, tough and environmentally friendly, has good application values in multiple fields and especially has outstanding advantages in the aspect of house furnishing material.

Description

technical field [0001] The invention relates to the technical field of PVC foam boards, in particular to a nano-cellulose toughened high heat-resistant 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.

AI Technical Summary

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
