The coated guard method of transmission tower spraying hot melt high molecular polymer of the invention described above, in order to improve filling capacity, the mobility of polymer better, described PVC is emulsion method polymeric polyvinyl chloride resin, K value 63, degree of polymerization 800-900.Show obvious aobvious low viscosity at low shear rates, table shows for Newtonian fluid characteristic at high shear rates.There is outstanding fusion rate, outstanding rheological behavior.
The transmission tower spraying hot melt high molecular polymer coated guard method of the invention described above, in order to improve better epoxy resin weatherability, ageing-resistant performance, prevent moisture from infiltrating, also add the isocyanates of 2-5% and the organic siliconresin of 2-5%.
Behind the surface of the fastening structure handled well, this high molecular polymer of even application, can reach etch-proof effect.
The present invention has the following advantages:
1. spraying hot melt high molecular polymer of the present invention has the fastening and anti-loosening effect of raising securing member, can be filled to the gap of screw thread, pad and nut and structure.
2. spraying hot melt high molecular polymer of the present invention is used for the polymorphic structure of securing member connection levelling, cover the effect of hot melt high molecular polymer, can environmentally thermal creep stress formula, to change the hot melt mobility of anti-corrosion material, reaching can the object of blind.
3. spraying hot melt high molecular polymer of the present invention has good flexibility, can the change in displacement that causes of the reciprocal load of commensurate structure, can with well the coincideing of uncured ointment, occur without be full of cracks, good resistance to water.
4. the spraying hot melt high molecular polymer that the present invention adopts can fast filming, has ultraviolet-resistant aging, water-tolerant and aesthetic function, can prevent the infiltration such as dust and water.
5. simple to operate, the easy construction of spraying hot melt high molecular polymer means of defence of the present invention, the labyrinth protection that the securing member being applicable to the transmission tower in severe rugged environment connects, protection effect is good, and anti-corrosion life is long, without destruction under alternate load.
