Aramid pulp-modified highly-sealed PVC-NBR composite foaming plate and preparation method thereof

Abstract

The invention discloses an aramid pulp-modified highly-sealed PVC-NBR composite foaming plate and a preparation method thereof. According to the composite foaming plate, a PVC-NBR blended material is taken as a composite plate base material, aramid pulp is added to serve as a reinforced modifying material, effectively improves the strength and the wear resistance of the composite plate and improves the leakproofness of the composite material together with polyhydroxyalkanoate, the very good barrier property on water vapor is achieved, and under cooperation of other materials, the finally-prepared composite foaming plate is uniform in foaming, high in strength, firm and wearproof in surface, good in flame retardance, closed, waterproof, environmentally friendly and nontoxic and has the outstanding application advantages on home decoration materials.

Description

technical field [0001] The invention relates to the technical field of PVC foam boards, in particular to a highly sealed PVC-NBR composite foam board modified by aramid pulp 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
