Problems solved by technology

However, during use, construction personnel must derust the surface of the steel bar to be fixed and wipe it clean with acetone or alcohol, otherwise it will affect the fixation
However, in the face of some large-scale projects, rust removal staff will inevitably make mistakes, which may cause serious consequences in the end because of these small problems

Abstract

The invention discloses modified vinyl steel bar planting glue and a preparation method thereof. The modified vinyl steel bar planting glue comprises a component A and a component B; the component A comprises the following raw materials in parts by mass: 35-60 parts of vinyl ester resin, 15-30 parts of an olefinic polymerizable modifying agent, 5-10 parts of a toughening agent, 0.1-2 parts of a coupling agent, 0.5-5 parts of an accelerant and 10-20 parts of packing; and the component B comprises 25-40 parts of a curing agent, 10-25 parts of an initiator and 10-20 parts of a diluent. The prepared steel bar planting glue is high in adhesive property, good in ageing resistance and short in curing time, can be used in a rusted state, and is suitable for anchoring various materials.

Description

technical field [0001] The invention relates to the field of chemical materials, in particular to a modified vinyl planting glue and a preparation method thereof. Background technique [0002] In the field of construction, with the development and growth of some emerging industries in my country, not only the amount of planting glue is increasing, but also the quality requirements for planting glue are getting higher and higher. The original bonding process and adhesives have many deficiencies, such as using hot melt glue or polystyrene glue, which contains more than 40% low-molecular solvents, which is not conducive to the health of decoration construction workers. Most of the planting glue in the market has the disadvantages of high brittleness, large volatile content, air pollution, low viscosity of the glue, flow phenomenon, and short shelf life. [0003] In actual engineering operations, the reinforcement construction team will encounter a lot of rush repair work on ro...
