皇冠盖用高性能PE粘结涂料及其制备方法
摘要：
本发明公开了一种皇冠盖用高性能PE粘结涂料及其制备方法，按重量百分数记，包括以下组分：环氧树脂20‑40％、酚醛树脂2‑10％、氨基树脂1‑5％、有机溶剂30‑60％、催化剂0.1‑2％、聚酯树脂2‑8％。本发明通过采用聚酯树脂替代改性聚乙烯微粉蜡，聚酯树脂的极性键可以和垫片里的少量极性基团产生吸附作用，使得涂料的粘结强度更高，粘结效果更好。
摘要（英）：

The invention discloses a high-performance PE adhesive coating for a crown cap and a preparation method thereof. The high-performance PE adhesive coating is prepared from the following components by weight percent: 20-40% of epoxy resin, 2-10% of phenolic resin, 1-5% of amino resin, 30-60% of organic solvent, 0.1-2% of catalyst, and 2-8% of polyester resin. The polyester resin replaces modified polyethylene micronized wax, and polar bonds of the polyester resin can adsorb a few polar groups in a gasket, so that the adhesive strength of the coating is improved, and the adhesive effect is better.
