Description

一种无稳定剂污染的PVC厨柜
技术领域
本发明涉及的是一种无稳定剂污染的PVC厨柜，属于塑料加工工业技术领域。
背景技术
厨柜是现代家居的主要部件，既要防水性能好，受潮后不霉、不烂、不变形；又要防火性能好，即使是灶具不慎失火也烧不着，消除房屋的火灾隐患；还要绿色环保，无霉、无毒、无味。根据现代厨柜的功能要求，PVC材料是无可挑剔的最佳选材。虽然PVC材料的热稳定性差、120℃以上出现HCL分解的致命弱点，实际上与厨柜＜50℃温度的使用环境没有任何关系。所以，PVC材料同时具备防水、防霉、防火、耐酸、耐碱、耐腐、耐候、耐用、环保、美观等材质性能，能够让厨柜的功能质量达到无与伦比的特殊效果。
但是，由于PVC材料的材质坚硬、脆性，必须充分剪切混炼＜2纳米的原始微区核才能发挥PVC的材质性能，而且PVC材料在≥120℃温度开始分解HCL，但PVC制品的加工热熔温度180℃～220℃，必须添加稳定剂中和反应HCL，才能加工制作PVC制品。但是，从技术原理上讲，只要PVC材料在加工制作过程中出现了HCL分解，或者是添加了其它物质，就损坏了PVC材料的纳米晶体链结构，必然影响PVC材料的耐酸、耐碱、耐腐、耐候、耐用性能。所以，PVC材料1912年问世以来，始终没有PVC制品的制造技术，存在二大技术错误：
一是PVC制品的加工制作过程中，必须添加稳定剂中和反应HCL，既污染了PVC制品的环保性能，又破坏了PVC材料的纳米晶体链结构，大大降低了PVC制品的耐酸、耐碱、耐腐、耐候、耐用性能。尽管欧盟国家高度重视稳定剂的污染问题，早在上世纪九十年代计划2025年前开发出无毒稳定剂，但至今未见重大的技术性突破。
二是PVC制品加工制作过程的热熔历史太长(约300～600秒)，必然造成PVC材料的热降解现象非常严重，虽然有稳定剂中和反应HCL，实质上严重损坏PVC材料的纳米晶体链结构，造成了PVC材料在阳光紫外线照射下容易分解的错误认识。换言之，只要PVC制品出现HCL分解，即使在没有阳光紫外线照射的黑暗环境中，活跃的HCL同样也会出现泛黄变色的老化现象。
由此可见，开辟一种无稳定剂污染的PVC制品制造技术，是全世界科技界梦寐以求、望而却步的重大科研课题。
发明内容
本发明的目的在于针对传统厨柜的功能质量缺陷，开辟一种无稳定剂污染的PVC厨柜新技术，本发明技术的解决方案是：(一)根据PVC材料在≤250℃温度中停留100秒内不分解HCL的特点，紧紧围绕60秒内加工制作PVC制品的科研课题开展技术攻关，使用本人发明的一种无稳定剂污染的PVC粒料、精确衡量落料机、超高压单螺杆挤出机等产业链制造技术，根据PVC厨柜型材的规格形状，发明一系列射孔流道挤出成型模，设计一系列加工制作PVC厨柜型材的操作工艺技术。使PVC厨柜型材的加工热熔时间控制在45秒钟之内，远离PVC材料的HCL分解点。(二)根据设计规格制造一种防水、防霉、防火、耐酸、耐碱、耐腐、耐用、环保、美观的PVC厨柜。
本发明的优点
(一)一种无稳定剂污染的PVC厨柜，同时具备防水、防霉、防火、耐酸、耐碱、耐腐、耐用、环保、美观等综合功能。
(二)一种无稳定剂污染的PVC厨柜，绿色环保，无霉、无毒、无味。
(三)一种无稳定剂污染的PVC厨柜，装饰效果好，高档豪华、坚固耐用。
(四)一种无稳定剂污染的PVC厨柜，使用寿命500年以上，是21世纪的新技术、新材料、新产品。
具体实施方式
实施例：超高压挤出成型技术制造PVC材料
工作内容：制造一种无稳定剂污染的PVC厨柜
挤出机口径Φ65mm，螺杆压缩比32倍，螺杆转速58转/分，电机功率10kw。
操作过程：(一)第一步采用移动式加热装置对超高压单螺杆挤出成型机加热到180℃，射孔流道挤出成型模加热到195℃，然后移开挤出机筒的加热装置，第二步启动超高压单螺杆挤出成型机，添加一些软质PVC开机料，第三步启动精确衡量落料机，逐渐加料使超高压单螺杆挤出成型机进入正常工作状态，第四步打开挤出机筒的冷却装置，使机筒出口的温度稳定在≤170℃，第五步打开挤出螺杆冷却装置，将射孔流道挤出成型模的温度稳定在≤195℃，此次PVC厨柜型材的加工热熔时间38秒，远离PVC材料的HCL分解点，每小时产量42kg，连续生产60天未见黄料、结碳现象。(二)根据设计规格加工制作一种防水、防霉、防火、耐酸、耐碱、耐腐、耐用、环保、美观的PVC厨柜。
