Abstract

La présente invention concerne une composition de PVC écologique, une méthode de préparation de celle-ci et un matériau de construction la contenant, et plus spécifiquement une composition de PVC écologique comprenant une résine PVC, un stabilisateur sans plomb et une poudre de sol jaune ou une poudre d'argile blanche de 200-6000 mesh avec une teneur en eau de 15,0 % ou moins, une méthode de préparation de celle-ci et un matériau de construction la contenant. Selon la présente invention, il est possible d'obtenir une composition de PVC écologique sans produire de matériaux dangereux, en particulier des métaux lourds dangereux, par rapport à un matériau de construction contenant une composition de PVC connue, qui a des effets antibactériens et fongicides à cause de la production de rayonnements dans l'infrarouge lointain et d'anions, qui maintient continuellement des propriétés physiques conformes à la norme KS, qui présente en particulier une texture et une couleur excellentes et avec peu ou pas de décoloration causée par les rayonnements ultraviolets en cas d'utilisation de sol jaune et qui présente une couleur de haute qualité à cause de la coloration naturelle en cas d'utilisation d'argile blanche cuite, et qui présente une photostabilité supérieure aux rayonnements ultraviolets et une résistance aux intempéries même sans contenir de coûteux agents de protection contre les UV contrairement aux produits contenant un agent de protection contre les UV, une méthode de production de celle-ci, et un matériau de construction la contenant.
