FIELD: process engineering.
SUBSTANCE: invention relates to construction materials, particularly, to composite construction cardboard with plastic coat and to method of its fabrication. Proposed cardboard can comprise one or more plies of suspension with submerged fibrous mats. Outer plastic coat is mechanically secured to suspension underlying ply. Said plastic layer s chemically bound to form crosswise chemical bonds with polymer admixtures in suspension ply.
EFFECT: hard construction cardboard wit polymer matrix, longer life and higher capacity.
