Abstract
The invention relates to rustproof concrete used synthetic fiber, which is prepared with the following components: 1.0 percent to 20 percent of a vapour-phase inhibitor and 80.0 and 99.0 percent of a polymer. The preparation method of the rustproof concrete used synthetic fiber comprises the steps that : 1) the solid vapour-phase inhibitor mixture is mixed uniformly and is mixed together with the polymer before the mixture is granulated, thus getting polymer master batches; 2) the polymer master batches are mixed with a fresh polymer without solid vapour-phase inhibitor, and fiber precursor is spun out; 3) the liquid vapour-phase inhibitor is beaten and mixed in a spinning finish before the mixture is emulsified into stable back spinning oil solutions which are applied on fiber; 4) the fiber applied with the oil solutions is drawn, thermoformed and cut off before the fiber is packed. The inhibitor contained in the rustproof concrete used synthetic fiber can be released slowly during the use of concrete, and protects steel bars well after the released inhibitor arrives at the surface of the steel bars through the capillary bores in the concrete. When the fiber is stretched or broken under stress, the inhibitor can be released quickly; in this way, the fiber is rustproof when the inhibitor inhibits the concrete from cracking.
