Description
Technical field
The present invention relates to a kind of manufacture method of packing with steel-plastic composite steel belt.
Technical background
Steel band is a kind of narrow and long thin steel bar of producing in order to adapt to different industrial department needs, and it is extensive use of in carton, wooden case and packings such as chemical products and metal material are tied up.Mainly contain three kinds of the steel band that turns blue, japanning steel band and galvanized steel strips at present.The steel band that turns blue make moist or meet water after easily get rusty, etch resistant properties is poor.The face coat poor adhesive force of japanning steel band and easily aging coming off.Galvanized steel strip has pollution and cost height to environment in manufacture process.Steel-plastic composite steel belt is made of steel band coating plastic layer, and it is good to have a packaging character, and etch resistant properties is strong, and manufacture process is polluted little characteristics.Disclose a kind of plastic-coated steel band and special equipment and manufacture method in Chinese patent application 200410076792.7, the method that mainly adopts extrusion molding to coat is finished the plastic overmold to steel band, and its manufacturing process is comparatively complicated, and production cost is also higher.
Summary of the invention
Technical problem to be solved by this invention is to provide at the deficiency that above-mentioned prior art exists that a kind of technology is easy, production cost is low, efficient is high, the manufacture method of the steel-plastic composite steel belt of good product quality.
The present invention for the technical scheme that problem adopted of the above-mentioned proposition of solution is:
With a steel band that minute cuts bar processings of turning blue earlier, after the steel band after the processing of turning blue cools, enter high-pressure electrostatic plastic-blasting device and carry out surface plastic spraying, the steel band behind the plastic-blasting is finalized the design through air cooling, promptly makes steel-plastic composite steel belt.
Press such scheme, it is to cut bar with the expansion of thin plate coil of strip and along the branch that vertically carries out that coil of strip launches that described branch cuts bar, divides the other end that cuts bar to reclaim rolling again.
Press such scheme, describedly turn blue that to handle be that a steel band that minute cuts bar is sent into the processing of turning blue of eddy-current heating blueing furnace, the treatment temperature of turning blue is 700-750 ℃.
Press such scheme, the high-temperature steel belt after the processing of turning blue, enters airtight high-pressure electrostatic plastic-blasting device and carries out surface plastic spraying to 185-230 ℃ through air-cooled; The electrostatic potential of high-pressure electrostatic plastic-blasting device is 80～100kv.
Press such scheme, apply the plastic coating of 0.06-0.8mm thickness through the surrounded surface of the steel band of plastic-blasting.
Press such scheme, the plastic-blasting raw material is high density polyethylene (HDPE), polypropylene, polyamide, polyvinyl chloride or indoor type epoxy polyester powder etc., and the plastic powders diameter is less than 0.2mm, and auxiliary material is pigment, filler and auxiliary agent.
Press such scheme, the steel band behind the plastic-blasting is finalized the design after air cooling, obtains steel-plastic composite steel belt, and its rolling speed is 4～6m/min.
Press such scheme, the width of steel band that described branch cuts bar is 8～32mm.
Beneficial effect of the present invention is: 1, technical process is succinct, and easy to operate controlled, equipment investment is little, and production cost is low, and is easy to utilize.2, the waste heat after manufacturing process makes full use of eddy-current heating and turns blue carries out plastic-blasting, forms integrated continuous production, energy-conservation a large amount of energy consumptions.3, plastic-blasting is to carry out in airtight generator, the plastic powders about 80% of spray gun ejection is adsorbed to surface of steel plate, and remainder is deposited to the powder spraying chamber bottom, collects the back and utilizes again by powder pump and new powder, save raw material effectively, also cleaned production environment simultaneously.4, utilize the principle plastic-blasting of high-pressure electrostatic absorption, coat quality height, attractive in appearance, cohesive force is big, the production efficiency height.
