Abstract
一种高拉伸强度的多元混合夹杂PVB膜片，是由下列原料及其重量份配比而成：69-93份聚乙烯醇缩丁醛、1-10份紫外光吸收剂、5-20份纳米纤维素和0.8-1.2份硅烷偶联剂。该膜片的生产方法是按前述配比值，将纳米纤维素、紫外光吸收剂、硅烷偶联剂加入到聚乙烯醇缩丁醛中，在锥混机中充分搅拌后经喂料器送入双螺杆挤出机，加热到140-150℃进行混炼、挤压，由模头挤出流延成型，制得厚度为0.38-0.76mm的本PVB膜片。因生产本膜片中的分子级纳米纤维有丰富的-OH基团，与纳米TiO2生成钛基醇，再与玻璃表面的Si-OH反应生成结合牢固的Ti-O-Si键，最终形成网状结构，使膜片大大提高拉伸强度、塑性及与玻璃的粘接强度。
Description
技术领域
本发明涉及高分子材料改性技术领域，特别是一种高拉伸强度的多元混合夹杂PVB膜片。
背景技术
随着人们生活水平的提高，设计住宅、商业等设施时主要考虑建筑物的功能、审美、环保和可建造性，但是建筑物中大量使用的玻璃材料是建筑物结构中较薄弱的环节，必须要对低概率的自然灾害和恶性攻击予以考虑。因此，中间夹有PVB膜片的夹层玻璃作为安全玻璃的重要形式，由于其良好的抗冲击性能和抗贯穿性能，破碎后无碎片飞溅，同时一定程度地降低噪声污染、光污染，被广泛应用于汽车、建筑、安保等相关领域。现有技术中如CN1284911、CN1518494分别公开由部分缩醛化的聚乙烯醇制成含增塑剂的薄膜的技术。CN 101608046A公开了通过调节偶联剂来满足不同粘结强度要求的技术。CN10962462公开了一种提高夹层玻璃阻燃性能的方法。然而，作为PVB夹层玻璃用时，其重要的物理性能指标如抗拉强度、断裂伸长率一直与国际高端产品相差甚远。这些性能恰恰是安全玻璃安全性的重要体现。因此，在保持原有PVB膜片的各种优异性，进一步提高PVB膜片的物理性能，特别是力学性能是目前亟待解决的问题。
发明内容
本发明要解决的技术问题是针对现有夹层玻璃用PVB膜片存在的拉伸强度较低、断裂伸长率较低的技术状况，提供一种添加纳米纤维素，运用多元混合夹杂复合原理制作成的高拉伸强度的多元混合夹杂PVB膜片。
解决上述技术问题采用的技术方案是：本高拉伸强度的多元混合夹杂PVB膜片，由下列原料及其重量份配比而成：69-93份聚乙烯醇缩丁醛、1-10份紫外光吸收剂、5-20份纳米纤维素和0.8-1.2份KH550型的γ-氨丙基三乙氧基硅烷或KH570型的γ-甲基丙烯酰氧-丙基三甲氧基硅烷。
所说的紫外光吸收剂为纳米级的SiO2、TiO2、ZnO、MgO中任一种。
所说的紫外光吸收剂为纳米级TiO2。
所说的纳米纤维素为由浙江农林大学木质资源综合利用国家工程中心按生物机械分丝方法制得的纳米纤维素。该方法已在本申请人申请的CN201110002108.0专利材料中公开，请参阅。
本发明的有益效果是：
(1)纳米二氧化钛与纳米纤维素形成的氢键等分子间作用力使二氧化钛被吸附到纤维素上，然后再通过硅烷偶联剂实现提高纳米纤维素在弱极性体系中的分散性能。解决了过去生产过程TiO2纳米晶体难以均匀分散，导致产品质量稳定性差的问题。
(2)纳米纤维素本身的网状结构以及其中含有丰富的-OH基团，与纳米TiO2经高温、高压反应生成钛醇基，该基团与玻璃表面的Si-OH反应生成牢固的Ti-O-Si键，而且分子级的纳米纤维素更易形成硅醇基和钛醇基，从而形成更多数量的Ti-O-Si键，最终形成一种牢固的三元混合夹杂的网状结构。大大提高了PVB膜片的拉伸强度、塑性以及与玻璃的粘接强度。
(3)红石型纳米TiO2对紫外线UVA(315-400nm)和UVB(280-315nm)都具有很好的屏蔽和负离子释放作用。可有效地解决紫外线给人们造成的光污染和净化空气问题。
具体实施方法
本发明下面结合实施例作进一步详述：先将各原料及其重量份配比值按八项实施例列于表1：
实施例1(对照表1实施例1的原料及重量份配比值)：将5份纳米纤维素、1份纳米SiO2、0.8份KH550型γ-氨丙基三乙氧基硅烷(简称KH550偶联剂)加入到69份聚乙烯醇缩丁醛(PVB)中，在锥混机中充分搅拌后经喂料器送入双螺杆挤出机，加热到145℃进行混炼、挤压，由模头挤出流延成型，制得厚度为0.39mm的本高拉伸强度的多元夹杂PVB膜片(简称本膜片)。
其余实施例2-8均对照表1对应实施例的原料及其重量份配比值，与实施例1相同方法制成本膜片，从本膜片的综合性能考虑，其中以实施例6、7优选。
现将按实施例1-8制得的本膜片测试性能介绍于表2：
