应用于节段预制拼装桥的结构胶
摘要：
本发明公开了一种应用于节段预制拼装桥的结构胶，包括重量份数比为3:1的A组分和B组分；其中，每份所述A组分包括如下原料：E51环氧树脂、EL51环氧树脂1、稀释剂、增韧剂、填料、Y-氨基丙基三乙氧基硅烷、触变剂以及消泡剂；每份所述B组分包括如下原料：固化剂、填料、Y-氨基丙基三乙氧基硅烷、气相二氧化硅、铁黑以及固化促进剂。本发明综合性能优良，具有较好的耐温性、耐久性，在低限温度条件下，12h抗压强度大于60MPa；24h抗压强度大于80MPa；7d抗压强度大于120MPa，是一种高强度结构胶。
摘要（英）：

The invention presents a structural adhesive for precast segment assembling bridge, which includes part A and part B with weight proportion of 3:1. Part A contains the following ingredients: E51 epoxy, EL51 epoxy1, diluent, flexibilizer, filler, APTES, thixotropic agent, defoamer; part B contains curing agent, filler, APTES, fumed silica, iron oxide black and curing catalyst. This invention has excellent overall properties and good thermal endurance and durability. in low limit temperature, its compressive strength during 12h is more than 60MPa, that during 24hr is more than 80MPa and during 7d is more than 120MPa, which is a structural adhesive with high strength.
