用聚合物粉末改性无溶剂环氧胶粘剂

Modification of Solvent Free Epoxy Adhesives by Polymer Powder

无溶剂环氧胶粘剂有许多缺点急待克服，其中最主要的缺点是韧性低，通过加入各种无机填料或有机填加剂（低聚物或增塑剂）来进行改性，均收效不大。但用某些高分子量的聚合物粉末作填加剂，对无溶剂环氧胶粘剂进行改性，收到了预期的效果，有一定实用价值。

ome deficiencies exist in some freeepoxy adhesive systems.The brittleness oneof these deficiencies has not been improvedsuccesfully by inorganic filler or organic additive (telomers or plasticizers). But it wasfound that the modification by polymerpowder fillers was effective.
