Abstract
The utility model relates to a zinc and epoxy double-coating steel bar. A base material steel bar is arranged in the center of the zinc and epoxy double-coating steel bar; a zinc and epoxy double-layer coating formed by adhering a zinc layer on the bottom layer and an epoxy coating on the surface layer is arranged outside the center base material; the zinc and epoxy double-layer coating is tightly combined with the center base material steel bar to form a whole. During the manufacturing, liquid metal zinc is coated on the surface of the clean steel bar by a thermal coating method to form the bottom zinc layer; the surface epoxy coating is coated on the surface of the bottom zinc layer. The zinc layer and the epoxy layer are adhered together to form the zinc and epoxy double-layer coating. According to the zinc and epoxy double-coating steel bar, harmful effects caused by coating damage and miss-coating of micro holes are avoided; by the zinc layer, a mechanical shielding and cathode protection unit function is realized. When the coating is damaged, and a corrosion medium exists, the metal coating can protect a steel base body from being corroded; the harmful effects caused by the damage and the shortcoming of the epoxy coating are effectively eliminated; the corrosion resistance is guaranteed; the service life of a building is guaranteed.
Description
Technical field
The utility model belongs to the erosion shield technical field, is specifically related to zinc, the two coated reinforcements of epoxy.
Background technology
The epoxy coating reinforcing bar is to adopt electrostatic coating method, epoxy powder is sprayed on a kind of reinforcing bar with coating of the surface production of common Ribbed Bar or normal optical round bar.Because epoxy resin powder coating is one of best anticorrosive paint of acid-proof in numerous coating materials, alkali characteristic, can effectively intercept corrosive deposit, the reinforcing bar with epoxy resin powder coating is applied on the surface, and its resistance to corrosion obviously improves, and effectively prolongs the service life of building.By Electrostatic Spray Technology, form evenly, fine and closely be combined firm epoxy coating with reinforcing bar, for other anti-corrosion measure, tool technology, performance and cost advantage.Therefore the development space of its domestic and international market is very wide.The epoxy resin powder coating reinforcing bar is widely used in being in industry in wet environment or the corrosive medium and civil buildings, general structures and road, bridge, harbour, in the reinforced concrete structure of harbour etc.
But, coating may appear damaging in the cast of the lifting of epoxy coating reinforcing bar, processing, carrying and colligation and concrete, and epoxy coating is once damage, and resistance to corrosion reduces, and directly influences the service life of building.In addition, unavoidably have the micropore of holiday during the coating epoxy coating, the existence of holiday micropore can reduce resistance to corrosion equally, influences the service life of building.Though can take reclamation activities to overcome coating damages and the caused harmful effect of holiday micropore, but reclamation activities one is cumbersome, expend man-hour, increase cost, moreover can not absolutely eliminate this reduction epoxy coating reinforcing bar resistance to corrosion, shorten the building harmful effect in service life.Therefore, be necessary to take more efficiently measure, overcome coating fully and damage and the caused harmful effect of holiday micropore the building service life of guaranteeing to use the epoxy coating reinforcing bar.
Summary of the invention
The utility model provides a kind of zinc, the two coated reinforcements of epoxy based on the existing problem of existing epoxy coating reinforcing bar.
The technical solution of the utility model is:
The two coated reinforcements of zinc, epoxy, its center is the base material reinforcing bar, the base material reinforcing bar at center is outer by zinc, epoxy pair coatings that are bonded together and formed by bottom zinc layer and surface layer epoxy coating; The base material reinforcing bar at zinc, the two coatings of epoxy and center is closely as one.
Use zinc, the two coated reinforcements of epoxy, can overcome coating and damage and the caused harmful effect of holiday micropore.In the utility model, the effect of epoxy coating is identical with role in existing epoxy coating reinforcing bar, and mechanical masking and cathodic protection synergy have then been played in the increase of zinc layer.When coating generation breakage, when corrosive medium exists, sprayed metal coating can be sacrificed oneself, and the protection steel substrate does not corrode.The zinc layer can eliminate effectively that epoxy coating damages and the caused harmful effect of defective, and its resistance to corrosion is more guaranteed, more can guarantee building service life.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: the 1st, base material reinforcing bar, the 2nd, zinc layer, the 3rd, epoxy coating.
The specific embodiment
Referring to Fig. 1, the utility model zinc, the two coated reinforcements of epoxy, its center is base material reinforcing bar 1, base material reinforcing bar 1 outer two coatings at center are made up of bottom zinc layer 2 and surface layer epoxy coating 3.Bottom zinc layer 2 is bonded together with surface layer epoxy coating 3, forms zinc, the two coatings of epoxy jointly, and the base material reinforcing bar 1 at zinc, the two coatings of epoxy and center is closely as one.
During making, adopt heat spraying method liquid metal zinc to be sprayed on base material reinforcing bar 1 surface at the center of cleaning earlier, form bottom zinc layer 2, zinc layer 2 thickness 50～100 μ m; The surface layer epoxy coating is coated in bottom zinc layer 2 surface, epoxy coating 3 thickness 150～350 μ m.Zinc layer 2 is bonded together with epoxy coating 3, forms the two coatings of zinc, epoxy that gross thickness is 200～450 μ m jointly, and zinc, the two coatings of epoxy form zinc, the two coated reinforcements of epoxy with the base material reinforcing bar.
