Problems solved by technology

[0002] PU air ducts are generally composed of PU film and steel wires. At present, most PU air ducts on the market use copper-plated steel wires. Since the pipes are discharged through the water tank, the copper-plated steel wires will stick to water, which will cause rust and discoloration. , affecting the overall appearance and quality, and if the copper-coated steel wire can be replaced by PU plastic-coated steel wire, the above problems can be effectively solved
[0003] However, most of the traditional plastic-coated steel wires have the problem that the outer coating and the inner steel wire are not firmly bonded. The reason is that the outer coating has poor viscosity, so it is necessary to improve

Abstract

The invention discloses a PU plastic-coated steel wire, and a preparation method and an application thereof, and relates to the field of materials. The master batch of the outer coating layer of the PU plastic-coated steel wire is prepared from, by weight, 34-48 parts of polyurethane resin, 8-18 parts of an organic solvent, 8-15 parts of glycerol ester of rosin, 1.5-2.2 parts of dibutyltin dilaurate and 12-25 parts of cellosilk. The raw materials of the master batch of the outer coating layer of the coated steel wire are optimized and selected to effectively improve the viscosity of the outercoating layer, so that the bonding strength between the outer coating layer and a steel wire is guaranteed, and the quality of the finished product is improved; and the master batch homologous with aPU material is adopted in the outer coating layer of the coated steel wire, so a PU pipe prepared from the coated steel wire can improve the bonding performance between the coated steel wire and a PUrubber sheet, thereby the strength of the PU pipe is guaranteed.

Description

technical field [0001] The invention relates to the field of materials, in particular to a PU plastic-coated steel wire and a preparation method and application thereof. Background technique [0002] PU air ducts are generally composed of PU film and steel wires. At present, most PU air ducts on the market use copper-plated steel wires. Since the pipes are discharged through the water tank, the copper-plated steel wires will stick to water, which will cause rust and discoloration. , affecting the overall appearance and quality, and if the copper-coated steel wire can be replaced by PU plastic-coated steel wire, the above problems can be effectively solved. [0003] However, most of the traditional plastic-coated steel wires have the problem of weak bonding between the outer coating and the inner steel wire. The reason is that the adhesion of the outer coating is poor, so it is necessary to improve it. Contents of the invention [0004] The object of the present invention ...
