Abstract

The invention discloses solvent-free spraying type epoxy putty. The solvent-free spraying type epoxy putty comprises an epoxy resin component, a curing agent component and a functional filler component, the epoxy putty has good bonding performance with concrete, shows excellent mechanical properties, does not contain volatile solvents, has nonvolatile matter content of 99% or more, is environmentally friendly, is beneficial to protection of the health of workers, can be used for spraying construction, has high construction efficiency, can adapt to construction of different base material shapesand adopts an airless spraying mode, and the maximum one-time forming thickness can reach 2mm; in addition, the epoxy putty product is in a three-component form, the filler is a single component, andno filler settlement risk exists in the storage period.

Description

technical field [0001] The invention relates to an epoxy putty, in particular to a solvent-free sprayable epoxy putty material used for durable repair of isolated concrete and a protective coating structure, belonging to the field of building materials. Background technique [0002] Concrete is an important part of building materials. It has many advantages such as easy material acquisition and good durability, and is widely used in construction projects, bridge projects, water conservancy projects and traffic projects. However, it is prone to cracks during production, maintenance and use. , honeycomb, pitted surface and defects and other diseases, these diseases affect the appearance of the concrete structure, and even affect the durability of the structure, therefore, it is necessary to repair and protect the concrete. [0003] In the field of building structure repair and protection, the isolated concrete durability repair and protective coating structure introduced in re...
