Precast concrete component surface repairing agent
The invention discloses a surface repairing agent for a precast concrete component. The surface repairing agent is prepared from a component A and a component B, the component A is a mixture of epoxy resin and inorganic filler, and the component B is a mixture of a curing agent and a diluent; the mass ratio of the curing agent to the diluent in the component B is 7: 3; the mass ratio of the component A to the component B is 10: 1; the epoxy resin in the component A is waterborne epoxy resin prepared from low-viscosity polyether hyperbranched epoxy resin. The concrete segment repairing agent has excellent physical and chemical properties. The main physical and chemical properties are as follows: the adhesive force is strong; the curing is convenient; the contractility is low; the mechanical property is excellent; the repairing agent has good chemical stability and is specially used for repairing surface defects of concrete prefabricated parts.
本发明公开了一种混凝土预制构件表面修补剂，所用原料包括A组分和B组分；A组分为环氧树脂与无机填料混合，B组分为固化剂与稀释剂混合；B组分中固化剂和稀释剂的质量比为7:3；A组分∶B组分的质量比为10∶1；A组分中的环氧树脂为一种低黏度聚醚型超支化环氧树脂制备的水性环氧树脂。该混凝土管片修补剂，具有优异的物理化学性能。其主要的物理化学性能有：粘附力强；固化方便；收缩性低；力学性能优良；化学稳定性好，专用于混凝土预制构件表面缺陷的修补。
