Abstract
The utility model relates to a polyvinyl composite steel-plastic structure which comprises a metallic matrix. The utility model is characterized in that a polyethylene plastic mixed layer is arranged on the metallic matrix; a plastic bottom layer is arranged between the polyethylene plastic mixed layer and the metallic matrix; the outside of the polyethylene plastic mixed layer is coated with a polyethylene layer. The utility model has the advantages that the polyvinyl composite steel-plastic structure has corrosion protection performance, bonding strength is increased, peeling strength is increased by 4-5 times as compared with the prior art, shearing strength is greatly increased, construction process is simple and convenient, cost is low, and temperature-resistant range is form-60DEG. C to 90DEG. C.
Description
The utility model relates to the member structure, the compound steel-plastic structure of particularly a kind of corrosion resistant polyethylene.
Present developing rapidly owing to chemical industry, metallurgy and special industry, more and more big to the resistant material demand, and all kinds of compound pipeline complex pipelines or container that present chemical industry is used, generally be at steel matrix inner surface spot welding wire netting, be connected with the steel body by the polyethylene of wire netting fusing, its peel strength is not high, second kind of form is to adopt heat to roll lining, equipment or pipeline heating are rolled, the peel strength that polyethylene is melted in obtain polyethylene layer and steel matrix on the steel equipment is not high yet, be difficult to reach requirement, and temperature requirement height in the construction.Complex manufacturing such as the pipeline of its making or container, involve great expense.
The purpose of this utility model be to provide a kind of corrosion-resistant, peel strength is high, the compound steel-plastic structure of the polyethylene that easily manufactured cost is low.
Realize that scheme of the present utility model is as follows:
The compound steel-plastic structure of a kind of polyethylene comprises metallic matrix, it is characterized in that: polyethylene plastic cement mixed layer is arranged on metallic matrix, the plastic cement bottom is arranged between polyethylene plastic cement mixed layer and the metallic matrix, outer the carrying out of polyethylene plastic cement mixed layer has polyethylene layer.
Described plastic cement bottom is made by PE modified, introduces active group in the polyethylene molecule, by this active group again with other contain more that the living polymer polymerization generates.
Described polyethylene plastic cement mixed layer 3 by polyethylene powders and bottom powder according to a certain percentage powder formulated fuse into one on this one deck by heating.
The plastic layer gross thickness of the compound steel-plastic structure of polyethylene is 0.3mm～3mm.
The beneficial effects of the utility model are as follows: the adhesive strength of backing layer and metallic matrix greatly improves, and wherein existing scheme of peel strength improves 4～5 times, reaches 240N/2.5cm, and shear strength also significantly improves, greater than 9mpa.Its any surface finish, construction technology is simple, convenient, with low cost, and its temperature resistant range-60 ℃～90 ℃ is widely applicable.
Accompanying drawing is a cross-section structure of the present utility model.
Below in conjunction with accompanying drawing in detail embodiment is described in detail.
Polyethylene plastic cement mixed layer 3 is arranged on metallic matrix 1, between polyethylene plastic cement mixed layer 3 and the metallic matrix 1 plastic cement bottom 2 is arranged, polyethylene plastic cement mixed layer 3 outer carrying out have polyethylene layer 4.
Plastic cement bottom 2 is made by PE modified, introduces active group in the polyethylene molecule, by this active group again with other contain more that the living polymer polymerization generates.
Polyethylene plastic cement mixed layer 3 by polyethylene powders and bottom powder according to a certain percentage powder formulated fuse into one by this layer of polyethylene layer and bottom.The plastic layer gross thickness of the compound steel-plastic structure of polyethylene is 0.3mm～3mm.
The plastic cement bottom 2 that the utility model uses is made by PE modified, introduces active group in the polyethylene molecule, by this active group again with other contain more that the living polymer polymerization generates.Adopt this layer high molecule composite construction to connect metallic matrix and polyethylene, both kept poly excellent in chemical performance, improved greatly again and the metal bond strength between the iron and steel particularly.Utilize the utility model to can be made into all kinds of containers, chemical pipeline, equipment etc. are widely used, and process simply with low cost.
