Par exemple, pour r\u00e9duire la temp\u00e9rature de moulage de la r\u00e9sine de chlorure de polyvinyle, afin que les produits soient souples, il faut ajouter des plastifiants. Certains plastiques sont tr\u00e8s proches de la temp\u00e9rature de d\u00e9composition thermique et de la temp\u00e9rature du processus de moulage, et ne peuvent \u00eatre form\u00e9s sans l'ajout de stabilisateurs de chaleur.<\/p>\n<p>C'est pourquoi les additifs plastiques occupent une place particuli\u00e8rement importante dans le processus de moulage des mati\u00e8res plastiques. Mais les additifs plastiques traditionnels sont principalement issus de sources p\u00e9troli\u00e8res. Avec les progr\u00e8s de la sensibilisation \u00e0 la protection de l'environnement et \u00e0 la s\u00e9curit\u00e9, les additifs plastiques biosourc\u00e9s pr\u00e9sentent des caract\u00e9ristiques plus \u00e9lev\u00e9es en mati\u00e8re de s\u00e9curit\u00e9 et de protection de l'environnement, entre autres, et la transformation environnementale des additifs plastiques est devenue une tendance.<\/p>\n<p>Dans tous les additifs plastiques, les plastifiants repr\u00e9sentent une tr\u00e8s grande proportion, c'est l'utilisation actuelle du caoutchouc plastique zui une grande quantit\u00e9 d'additifs, 90% pour la r\u00e9sine PVC.<\/p>\n<p>Le r\u00f4le principal des plastifiants est d'\u00eatre ajout\u00e9s aux mat\u00e9riaux polym\u00e8res pour am\u00e9liorer leur plasticit\u00e9. Ils peuvent changer la nature du polym\u00e8re, augmenter sa plasticit\u00e9, sa flexibilit\u00e9, son \u00e9tirement et d'autres propri\u00e9t\u00e9s, ce qui le rend facile \u00e0 transformer.<\/p>\n<p>En fait, presque tous les proc\u00e9d\u00e9s de transformation des polym\u00e8res thermoplastiques utilisent des plastifiants dans une mesure plus ou moins grande. L'essence de la transformation des polym\u00e8res thermoplastiques est d'augmenter l'activit\u00e9 des mol\u00e9cules de polym\u00e8res en les chauffant, en affaiblissant leurs forces intermol\u00e9culaires, ce qui les rend plastiques.<\/p>\n<p>Cependant, pour certains polym\u00e8res polaires pr\u00e9sentant des forces intermol\u00e9culaires \u00e9lev\u00e9es et instables au chauffage, il devient tr\u00e8s difficile de les mouler par le seul chauffage, et les forces intermol\u00e9culaires \u00e9lev\u00e9es rendent les produits finis de ces polym\u00e8res durs, in\u00e9lastiques et flexibles sans ajout de plastifiants ou en quantit\u00e9s inad\u00e9quates.<\/p>\n<p>Pour fabriquer des produits en PVC souple, il faut ajouter une quantit\u00e9 suffisante de plastifiant. Parfois, la quantit\u00e9 ajout\u00e9e est m\u00eame sup\u00e9rieure \u00e0 50% de la masse totale du produit, par exemple, les produits m\u00e9dicaux en PVC, les jouets avec 35% \u00e0 40%, les produits d'emballage alimentaire avec environ 28%, la quantit\u00e9 ajout\u00e9e varie.<\/p>\n<p>L'apparition de plastifiants en r\u00e9duisant la temp\u00e9rature de transition vitreuse du polym\u00e8re, la temp\u00e9rature de fusion et le module d'\u00e9lasticit\u00e9 des \u00e9lastom\u00e8res, de sorte que les propri\u00e9t\u00e9s de traction, la flexibilit\u00e9, l'\u00e9longation du produit soient meilleures.<\/p>\n<p>Le m\u00e9canisme de plastification des plastifiants repose principalement sur l'effet de volume et l'effet de protection de deux aspects.<\/p>\n<p>1. Effet de volume<\/p>\n<p>Cet effet est d\u00fb au fait que l'ajout de plastifiants non polaires augmente la distance entre les mol\u00e9cules de polym\u00e8re, la force mol\u00e9culaire entre les mol\u00e9cules diminue, ce qui r\u00e9duit la force de van der Waals entre les mol\u00e9cules de r\u00e9sine, r\u00e9duisant ainsi la viscosit\u00e9 \u00e0 l'\u00e9tat fondu des mati\u00e8res plastiques. Cet effet augmentera avec l'ajout de plastifiants, et la structure des plastifiants aura \u00e9galement un impact sur l'efficacit\u00e9 de la plastification.<\/p>\n<p>2. Effet de blindage<\/p>\n<p>Cet effet est d\u00fb aux plastifiants polaires. L'ajout d'un plastifiant polaire renforce l'interaction entre le plastifiant polaire et le polym\u00e8re, ce qui r\u00e9duit la connexion polaire entre les polym\u00e8res et permet de r\u00e9duire la viscosit\u00e9 \u00e0 l'\u00e9tat fondu.<\/p>\n<h2><strong>Plastifiants ignifuges de la m\u00eame s\u00e9rie<\/strong><\/h2>\n<table style=\"border-collapse: collapse;
