The invention discloses a steel adhesive which comprises a component A and a component B. The component A is composed of the following raw materials in parts by weight: 175-195 parts of epoxy resin E51, 35-55 parts of epoxy resin E44, 48-68 parts of a toughening agent, 1-2 parts of a silane coupling agent, 680-720 parts of quartz sand, 8-10 parts of fumed silica and 5-10 parts of tar or 5-10 partsof copper sulfate, and the component B is prepared from the following raw materials in parts by weight: 490-560 parts of a fatty amine curing agent, 1.5-2.5 parts of a silane coupling agent, 700-750parts of quartz sand, 8-12 parts of titanium dioxide and 8-12 parts of titanium dioxide, wherein and the component A and the component B are mixed according to the ratio of (2.5-3.5): 1 to obtain thesteel adhesive. The invention further discloses a concrete structure steel plate reinforcing method. The steel adhesive can wet and permeate steel parts and concrete, and therefore after the steel bonding glue is solidified, the overall shear strength and bonding strength of the product are greatly improved, and the bonding and solidifying effect is good.
本发明公开了一种粘钢胶，包括组分A和组分B，组分A是由以下重量份数的原料组成：环氧树脂E51 175‑195份；环氧树脂E44 35‑55份；增韧剂48‑68份；硅烷偶联剂1‑2份；石英砂680‑720份；气相二氧化硅8‑10份；焦油5‑10份或者硫酸铜5‑10份；组分B是由以下重量份数的原料组成：脂肪胺固化剂490‑560份；硅烷偶联剂1.5‑2.5份；石英砂700‑750份；钛白粉8‑12份；气相二氧化硅8‑12份；将组分A和组分B按照(2.5‑3.5)：1的比例配置获得粘钢胶。本发明还公开了采用粘钢胶进行混凝土结构的钢板加固方法，本发明粘钢胶可对钢件及混凝土的润湿与渗透，从而在粘钢胶凝固后，产品整体的抗剪切强度和粘结强度得到大幅度提升，粘结固化效果好。
