改性聚乙烯醇建筑涂料的研制

Study On The Modified PVA as a Coating Material in Building

本文介绍了一种用甲苯二异氰酸酯对聚乙烯醇改性的方法 ,使其耐水性显著提高。改性成膜物加入各种填料 ,得到一种耐水性很强。

This article introduces a methord of using TDI to modify PVA,whose property of water resistance can be obviously improved.The modified film material is mixed with different stuffs,then we get a coatings which has a good property of water resistance and abrasion.
