一种线型水溶性聚磷腈高分子粘胶共混改性阻燃剂

Linear water-soluble polyphosphazene high-molecular adhesive blended modified fire retardant

Abstract

本发明公开了一种线型水溶性聚磷腈高分子阻燃剂的制备方法与其在共混改性阻燃粘胶膜中的应用。本发明所提供的线型聚磷腈结构如式I,其中的R1、R2为式II基团或式III基团中的任意一种,a为0—5的整数,b为1—6的整数,所述取代聚磷腈链中式II、式III基团的摩尔比为1:0—0.5。本发明的线型水溶性聚磷腈高分子,阻燃元素氮、磷含量高,能与粘胶共混制备阻燃性粘胶薄膜。处理后的粘胶薄膜具有阻燃性好,不发烟,阻燃耐久性能优良等特点。
The invention discloses a preparation method of a linear water-soluble polyphosphazene high-molecular fire retardant and application of the linear water-soluble polyphosphazene high-molecular fire retardant in a blended modified flame-retardant adhesive film. The linear polyphosphazene structure is shown as a formula I, wherein R1, R2 are any one of a formula II group or a formula III group; a is an integer from 0 to 5; b is an integer from 1 to 6; and the mole ratio of the formula II group and the formula III group which are contained in a substituted polyphosphazene chain is 1:0-0.5. The linear water-soluble polyphosphazene high-molecular fire retardant disclosed by the invention is high in flame-retardant element nitrogen and phosphorus content and can be blended with an adhesive to prepare the flame-retardant adhesive film; and the processed adhesive film has the characteristics of good fire retardance, no smoke, excellent flame-retardant and lasting property, and the like.
