Embodiment Construction
[0012] A highly sealed PVC-NBR composite foam board modified by aramid pulp. The composite foam board is made of the following raw materials in parts by weight: PVC 40, NBR 20, aramid pulp 6, polyhydroxyalkanoate 5. AC foaming agent 2, zirconium phosphate 5, calcium carbonate 2, tung oil 1, triethyl borate 1, light stabilizer 0.5, calcium zinc stabilizer 4, accelerator TMTD 0.4, stearic acid 0.5, vulcanizing agent PDM0. 8. Epoxy fatty acid methyl ester 5. Zinc methacrylate 2.
[0013] The preparation method of this embodiment composite foam board comprises the following steps:
[0014] (1) First put NBR into a mixer at 160°C for 25 minutes, then add PVC, aramid pulp, polyhydroxyalkanoate, zirconium phosphate, calcium carbonate, tung oil, light stabilizer, calcium zinc stabilizer, Epoxy fatty acid methyl ester, zinc methacrylate and the materials obtained in step (1), continue banburying for 40 minutes to obtain a composite base material, and the base material is naturally coo...

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. Unexpectedly, there are potential safety hazards duri...
