Title
(EN) VAPOR SCREEN COMPOSITION
(FR) COMPOSITION IMPERMEABLE AUX VAPEURS
Abstract
(EN)
The invention relates to a water-dispersible composition for making a water repellent paper with a low permeability for moisture. The composition comprises components (A) to (H), in the following amounts by dry weight (wt): (A) 5 to 89 wt % of polyvinyl butyral (PVB), (B) 1 to 20 wt % of styrene maleic imide (SMI), (C) 5 to 50 wt % of ethylene acrylate, (D) 0 to 20 wt % of polyvinyl alcohol or starch, (E) 0 to 7 wt % of wax, (F) 0 to 6 wt % of styrene maleic anhydride copolymer (SMA), (G) 0 to 70 wt % of styrene butadiene (SB) latex and (H) 0 to 70 wt % of talc. The invention further relates to an easily macerating moisture-proof paper comprising a base paper having coated on at least one surface thereof a layer of an aqueous emulsion comprising a water-dispersible composition, wherein the solid content in the aqueous emulsion is from 30 to 65 % by weight.
(FR)
L'invention concerne une composition dispersable dans l'eau permettant de fabriquer un papier hydrofuge a faible perméabilité à l'humidité. Cette composition comprend les constituants suivants (A) à (H), selon les quantités indiquées, en pourcentage par rapport au poids sec: (A) 5 à 89 %, butyral de polyvinyle (PVB), (B) 1à 20 %, imide maléique de styrène (SMI), (C) 5 à 50 %, acrylate d'éthylène, (D) 0 à 20 %, alcool de polyvinyle ou amidon, (E) 0 à 7 %, cire, (F) 0 à 6 %, copolymère d'anhydride maléique de styrène (SMA), (G) 0 à 70 %, latex de butadiène de styrène (SB) et (H) 0 à 70 % de talc. L'invention concerne également un papier imperméable à l'humidité dont la macération est aisée, qui comprend un papier de base revêtu, au moins sur une surface, d'une couche d'émulsion aqueuse renfermant une composition dispersable dans l'eau, la teneur en matières solides dans l'émulsion étant comprise entre 30 et 65 %, en poids.
