Para preparar espuma leve, antivibra\u00e7\u00e3o, de isolamento t\u00e9rmico e ac\u00fastico e adicionar agentes espumantes, alguns pl\u00e1sticos est\u00e3o muito pr\u00f3ximos da temperatura de decomposi\u00e7\u00e3o t\u00e9rmica e da temperatura do processo de moldagem, sem a adi\u00e7\u00e3o de estabilizadores de calor n\u00e3o podem ser formados.<\/p>\n<p>Portanto, os aditivos pl\u00e1sticos no processo de moldagem de pl\u00e1stico ocupam uma posi\u00e7\u00e3o particularmente importante. No entanto, os aditivos pl\u00e1sticos tradicionais s\u00e3o, em sua maioria, fontes \u00e0 base de petr\u00f3leo. Com o progresso da conscientiza\u00e7\u00e3o das pessoas em rela\u00e7\u00e3o \u00e0 prote\u00e7\u00e3o ambiental e \u00e0 seguran\u00e7a, os aditivos pl\u00e1sticos de base biol\u00f3gica apresentam maior seguran\u00e7a e prote\u00e7\u00e3o ambiental, al\u00e9m de outras caracter\u00edsticas, e os aditivos pl\u00e1sticos de transforma\u00e7\u00e3o ambiental se tornaram a tend\u00eancia.<\/p>\n<p>Em todos os aditivos pl\u00e1sticos, os plastificantes representam uma propor\u00e7\u00e3o muito grande, sendo que a borracha pl\u00e1stica atual usa uma grande quantidade de aditivos, 90% para resina de PVC.<\/p>\n<p>A principal fun\u00e7\u00e3o dos plastificantes \u00e9 adicionada aos materiais polim\u00e9ricos para melhorar sua plasticidade, podendo alterar a natureza do pol\u00edmero, aumentando sua plasticidade, flexibilidade, alongamento e outras propriedades, facilitando o processamento.<\/p>\n<p>De fato, quase todo o processamento de pol\u00edmeros termopl\u00e1sticos usar\u00e1 plastificantes em maior ou menor grau. A ess\u00eancia do processamento de pol\u00edmeros termopl\u00e1sticos \u00e9 aumentar a atividade das mol\u00e9culas de pol\u00edmero por meio do aquecimento, enfraquecendo suas for\u00e7as intermoleculares e, assim, tornando-as pl\u00e1sticas.<\/p>\n<p>No entanto, para alguns pol\u00edmeros polares com altas for\u00e7as intermoleculares e inst\u00e1veis ao aquecimento, torna-se muito dif\u00edcil moldar apenas com o aquecimento, e as fortes for\u00e7as intermoleculares tornam os produtos finais desses pol\u00edmeros duros, inel\u00e1sticos e flex\u00edveis sem a adi\u00e7\u00e3o de plastificantes ou em quantidades inadequadas.<\/p>\n<p>Para fabricar produtos de PVC flex\u00edvel, \u00e9 necess\u00e1rio adicionar uma quantidade suficiente de plastificante. \u00c0s vezes, a quantidade adicionada \u00e9 ainda maior que 50% da massa total do produto, por exemplo, produtos de PVC para uso m\u00e9dico, brinquedos com 35% a 40%, produtos de embalagem de alimentos com cerca de 28%, a quantidade adicionada varia.<\/p>\n<p>O aparecimento de plastificantes reduz a temperatura de transi\u00e7\u00e3o v\u00edtrea do pol\u00edmero, a temperatura de fus\u00e3o e o m\u00f3dulo de elasticidade dos elast\u00f4meros, de modo que as propriedades de tra\u00e7\u00e3o, a flexibilidade e o alongamento do produto sejam melhores.<\/p>\n<p>O mecanismo de plastifica\u00e7\u00e3o dos plastificantes se d\u00e1 principalmente por meio do efeito de volume e do efeito de prote\u00e7\u00e3o de dois aspectos.<\/p>\n<p>1. Efeito de volume<\/p>\n<p>Esse efeito ocorre porque a adi\u00e7\u00e3o de plastificantes n\u00e3o polares aumenta a dist\u00e2ncia entre as mol\u00e9culas de pol\u00edmero, a for\u00e7a molecular entre as mol\u00e9culas diminui, o que reduz a for\u00e7a de van der Waals entre as mol\u00e9culas de resina, reduzindo assim a viscosidade de fus\u00e3o dos pl\u00e1sticos. Esse efeito aumentar\u00e1 com a adi\u00e7\u00e3o de plastificantes, e a estrutura dos plastificantes tamb\u00e9m ter\u00e1 um impacto sobre a efici\u00eancia da plastifica\u00e7\u00e3o.<\/p>\n<p>2. Efeito de blindagem<\/p>\n<p>Esse efeito \u00e9 causado por plastificantes polares. O acr\u00e9scimo de plastificante polar aumenta a intera\u00e7\u00e3o entre o plastificante polar e o pol\u00edmero, o que reduz a conex\u00e3o polar entre os pol\u00edmeros e consegue reduzir a viscosidade da fus\u00e3o.<\/p>\n<h2><strong>Plastificantes retardantes de chama da mesma s\u00e9rie<\/strong><\/h2>\n<table style=\"border-collapse: collapse;
