Abstract
(EN) The invention belongs to the technical field of functional plastics and specifically relates to nano antibacterial and antifouling plastic particles for tables and chairs and a preparation method. Specifically: first, prefabricating a nanocomposite antibacterial agent and loading silver ions and zinc ions in nano-pores of a silica gel hydrolyzed by sodium methyl silicate, treating same by using a polytetrafluoroethylene emulsion and obtaining a nanocomposite antibacterial agent by means of centrifugal spray drying and sand milling. The nanocomposite antibacterial agent has both antibacterial properties and hydrophobic, self-cleaning properties. The nanocomposite antibacterial agent, polypropylene, high-density polyethylene, and the like are further granulated to obtain nano antibacterial and antifouling plastic particles for tables and chairs. Furthermore, zinc tungstate is compounded in the nanocomposite antibacterial agent. The present invention better aims at the basic performance requirements of plastic tables and chairs and, by means of a reasonable formula, cooperatively prepares nano antibacterial and anti-fouling plastic particles for tables and chairs. After an antibacterial plastic product is prepared, the nanocomposite antibacterial agent provides antibacterial and self-cleaning antifouling functions in a product and has stable and long-lasting antibacterial properties.
(FR) L'invention appartient au domaine technique des plastiques fonctionnels et se rapporte en particulier à des particules de plastique nanométriques antibactériennes et antisalissure pour tables et chaises et à un procédé de préparation. En particulier : le procédé consiste tout d'abord, à préfabriquer un agent antibactérien nanocomposite et à charger des ions argent et des ions zinc dans les nanopores d'un gel de silice hydrolysé par du méthyl silicate de sodium, à traiter ce dernier à l'aide d'une émulsion de polytétrafluoroéthylène et à obtenir un agent antibactérien nanocomposite au moyen d'un séchage par pulvérisation centrifuge et d'un broyage au sable. L'agent antibactérien nanocomposite présente à la fois des propriétés antibactériennes et des propriétés hydrophobes, autonettoyantes. L'agent antibactérien nanocomposite, le polypropylène, le polyéthylène haute densité et analogues sont en outre granulés pour obtenir des particules plastiques antibactériennes et antisalissure pour des tables et des chaises. En outre, du tungstate de zinc est mélangé dans l'agent antibactérien nanocomposite. La présente invention vise mieux les exigences de performance de base de tables et de chaises en plastique et, au moyen d'une formule raisonnable, prépare en coopération des particules plastiques antibactériennes et antisalissure nanométriques pour des tables et des chaises. Après la préparation d'un produit plastique antibactérien, l'agent antibactérien nanocomposite fournit des fonctions antibactériennes, antisalissure et autonettoyantes dans un produit et présente des propriétés antibactériennes stables et durables.
