Abstract
The steel pail with anticorrosive plastic inner container suitable for holding water-base paint and chemical material includes one pail body and one inner container. The plastic inner container is made with plastic and through pressing into sheet and vacuum forming in a pail-shaped hollow mold, and has the same inner diameter and shape as that of the pail body. The steel pail with anticorrosive plastic inner container is anticorrosive and can ensure the quality of the held material. The inner container has low cost and simple production process, and the steel pail may be reused to save resource.
Description
Technical field
The present invention relates to a kind of anticorrosion shaped steel pail that is applicable to splendid attire water paint, chemical, refer in particular to a kind of steel pail, the manufacture method of this steel pail is provided simultaneously with antiseptic plastic inner container.
Background technology
At present, steel pail in water paint, the use of chemical industry, because of water paint, chemical have certain water oxidisability and corrosive property, the easy oxidation and rusting of sheet tin of this bucket, packing barrel producer is usually when printing packing, handle with the yellow technology of plating iron sheet is inboard, or adopt iron sheet to cover plastic sheeting and carry out anti-corrosion treatment, pass through the weld seam muscle moulding of rising then and make bucket.No matter which kind of method all is before becoming bucket sheet tin to be carried out anti-corrosion treatment, but when becoming bucket, need carry out weld seam, the welding of handle ear, during welding, Huang is plated on the surface or film is destroyed.Yellow processing of plating or overlay film processing then must take to mend plating, mend to plate and generally use the polyester synthetic lacquer to plate brush, and the Corrosion Protection extreme difference at weld seam, handle ear place easily gets rusty, and influences the performance of whole metal bucket.Thus, these present steel pails, antiseptic property is poor, in service life, influences the quality of splendid attire product.Chinese patent application 200520093275.0 discloses safe oil drum, be provided with rubber liner in cylindrical metal bucket inside, when people in carrying during oil drum, in case bump or rub, elastic deformation can take place in inner bag, can not cause inner oil inflame or blast, actv. has ensured people's life security.The rubber liner volume is big, and inner bag thickness is dark, places the water paint of small size type or chemical packing barrel interior infeasible.
Summary of the invention
The invention provides that a kind of antiseptic property is good, safe in utilization, cost is low while the also steel pail of the band antiseptic plastic inner container of reusable edible of steel pail, second purpose of the present invention provides the manufacture method of the steel pail of this band antiseptic plastic inner container.Main innovation is plastic material is pressed into the sheet material barrel-shaped antiseptic plastic inner container of mould molding again, and this inner bag is embedded in the packing barrel inboard again.Specifically implement like this: the steel pail of band antiseptic plastic inner container, comprise staving, inner bag, it is characterized in that the staving inwall is covered with a plastic cement tubbiness inner bag, described tubbiness inner bag is pressed into sheet material with plastic material after barrel-shaped hollow mould vacuumizes moulding, the internal diameter tub consistent with shape and staving.Plastic inner container is very frivolous durable again, be embedded in it in steel pail after, do not need to deal with again, can keep apart barrel content and iron sheet fully, the antiseptic property height.And, after water paint or chemical use, can also slough inner bag, steel pail usefulness more capable of circulation has been saved resource.
The concrete manufacture method of the steel pail of this band antiseptic plastic inner container is:
1, moulding inner bag: in plastic material, add the plasticizer phthalic acid dioctyl ester, the addition of plasticizer is the 3-5% of plastic cement weight, the plasticizing back is pressed into sheet material with platen-press, it is suitable for reading to lie in the hollow barrel mould after sheet material is softening, vacuumizes from hollow barrel mould end opening sheet material absorption is formed the tubbiness inner bag;
2, paste: cementing on tubbiness inner bag outside face, steel is carried metal bucket be enclosed within on the inner bag, exerting pressure from internal bladder cavity makes its absorption be pasted on steel pail inwall.
The plastic material of indication can be PVC, PP, PE, PS etc. among the present invention, the range of temperatures of plasticizing is 150 ℃-200 ℃, temperature was 180 ℃-220 ℃ when platen-press was pressed into sheet material, the sinter point of sheet material is 120 ℃-150 ℃, it can be according to the plastic cement material of selecting for use, the temperature when determining the best plasticization temperature that meets the material characteristic, laminated sheet and the sinter point of sheet material.
In this manufacture method, the thickness that is pressed into sheet material is not laid down hard and fast rule, but thin damaged in order to stop, and considers cost simultaneously, and sheet thickness is good with 20-50S.
When inner bag is covered on barrel inwall, be to guarantee sticking effect, applied pressure is good with the 0.5-1 kilogram in the internal bladder cavity.
The steel pail of this band antiseptic plastic inner container has solved the anticorrosion problem of present steel pail fully, has guaranteed the moral character of contents, and inner bag is with low cost, and manufacture method is easy and safe and effective, and the steel pail is reusable edible also, has saved resource.
The specific embodiment
Embodiment 1, the steel pail of band antiseptic plastic inner container, comprise staving, inner bag, the staving inwall is covered with a PVC tubbiness inner bag, and described tubbiness inner bag is pressed into sheet material with the PVC raw material after barrel-shaped hollow mould vacuumizes moulding, the internal diameter tub consistent with shape and staving.
Concrete manufacture method is:
(1) moulding inner bag: in the PVC raw material, add the plasticizer phthalic acid dioctyl ester, the addition of plasticizer is the 3-5% of PVC weight, in 150 ℃-160 ℃ plasticizings down, be pressed into sheet material through 180 ℃ of-190 ℃ of platen-press again, it is suitable for reading that sheet material lies in the hollow barrel mould through 120 ℃-130 ℃ after softening, vacuumizes from hollow barrel mould end opening sheet material absorption is formed the tubbiness inner bag;
(2) paste: cementing on tubbiness inner bag outside face, the steel pail is enclosed within on the inner bag, exerting pressure from internal bladder cavity makes its absorption be pasted on steel pail inwall.
Embodiment 2, reference example 1, and plastic inner container is selected the PE material for use, and according to the material characteristic, the plasticization temperature of selecting for use is 180 ℃-200 ℃, and the temperature that platen-press is pressed into sheet material is 200 ℃-220 ℃, and the sheet material sinter point is 140 ℃-150 ℃.
For guaranteeing product design cost-cutting simultaneously, sheet thickness was controlled to be 20-50S when PE was pressed into sheet material; When inner bag was covered on barrel inwall, applied pressure was the 0.5-1 kilogram in the internal bladder cavity.
