High-temperature-resistant heat-insulating slow-bonding prestressed steel strand and preparation method thereof
The invention relates to the technical field of building materials, and particularly discloses a high-temperature-resistant heat-insulation type retard-bonded prestressed steel strand and a preparation method thereof. The invention discloses a high-temperature-resistant heat-insulation slow-bonding prestressed steel strand. The high-temperature-resistant heat-insulation slow-bonding prestressed steel strand comprises a slow-setting binder, prestressed twisted steel and a sheath, the retarding binder comprises 80-90 parts of resin, 10-15 parts of a curing agent, 8-12 parts of a diluent, 20-40 parts of a filler and 12-20 parts of a reinforcing aid; the preparation method of the reinforcing auxiliary agent comprises the following steps: uniformly mixing a vinyl chloride/vinyl acetate/maleic acid terpolymer, sodium sulfosuccinate and ammonium ferrous sulfate according to a weight ratio of (20-30): (5-10): (2-6); the preparation method of the filler comprises the following steps: adding 18-22 parts by weight of aluminate cement and 7-13 parts by weight of chopped asbestos fiber into 90-100 parts by weight of a polyethyleneimine solution, and reacting to obtain the filler. The obtained steel strand has excellent high temperature resistance and heat insulation performance.
