一种防护栏用胶粘剂、其制备方法及由其制成的高速公路用防护栏
摘要：
一种防护栏用胶粘剂，所述胶粘剂由A、B两组分组成，其中，A组分的重量组成为：环氧树脂100份、发泡剂12～32份、甲苯缩水甘油醚5～12份、丁腈橡胶5～11份；B组分的重量组成为：固化剂35份、三聚氰胺5～10份、多亚甲基多苯基多异氰酸酯改性三乙烯四胺8～17份；所述多亚甲基多苯基多异氰酸酯改性三乙烯四胺由多亚甲基多苯基多异氰酸酯和三乙烯四胺反应制得，多亚甲基多苯基多异氰酸酯和三乙烯四胺的用量份数比为100：25～46。同时本发明还公开了其相应的制备方法及由其制成的高速公路防护栏。该防护栏具有优异的力学强度、减震、缓冲、防水性、耐候性、安装简单、快捷、维护成本低等优势。
摘要（英）：

An adhesive for a guard rail is prepared from a component A and a component B, wherein the component A is prepared from 100 parts by weight of epoxy resin, 12-32 parts by weight of a foaming agent, 5-12 parts by weight of methylphenyl glycidyl ether and 5-11 parts by weight of nitrile rubber; the component B is prepared from 35 parts by weight of a curing agent, 5-10 parts by weight of melamine and 8-17 parts by weight of polymethylene polyphenyl polyisocyanate modified triethylenetetramine, wherein polymethylene polyphenyl polyisocyanate modified triethylenetetramine is prepared from polymethylene polyphenyl polyisocyanate and triethylenetetramine through a reaction, and the ratio of use parts of polymethylene polyphenyl polyisocyanate to triethylenetetramine is 100:(25-46). Meanwhile, the invention discloses a preparation method of the adhesive and a highway guard rail prepared from the adhesive. The guard rail has the advantages of being excellent in mechanical strength, damping property, cushioning property, waterproofness and weather fastness, simple and fast to mount, low in maintenance cost and the like.
