The invention discloses a kind of whole paper composite paper-plastic materials and the preparation method and application thereof, and preparation method comprises the following specific steps that: modified plastics film and whole paper reclaim paper hot pressing overlay film, and needle pierces micropunch processing, intersect lamination assembly；Hydrophobing agent is then dried spray treatment around assembly；Through High frequency heating at slab, whole paper composite paper-plastic material is cut into after cooling.The whole paper composite paper-plastic material is made of paper lamination, and paper internal void is sufficient filling with by thermoplastic.The present invention improves osmotic efficiency of the plastic melt inside paper, reduces because permeating the internal structural defects unevenly formed, improves the mechanical property of composite paper-plastic material；Guarantee that bubbling phenomenon does not occur in plate preparation process；Moistureproof and waterproof performance is improved, prolongs the service life, makes to can be used for outdoor composite floor board and door-plate field it is suitable for indoor and outdoor wet environment. |
