Away from bad defects such as not enough, rotten of stretching, flanging bore crackings, have a strong impact on production efficiency.
At present, at home, anti-corrosion aluminium foil uses acrylic resin as anticorrosive coat to improve anticorrosive coat, the carrying of employing
High preserving method is to double anticorrosive coat coating thickness, for tackling the production of a high pitch of fins two device product, typically adopts low
Speed, multi-step tension, increase punching oil using method maintain the production of such product.8011 commonly used conjunctions of existing market
Gold can't fully meet demand, do not break through conventional sheet away from the limit, it is low to rush fast more conventional speed, and punching oil consumption increases,
Mould maintenance period is short etc., increased production cost.
Utility model content
The technical problems to be solved in the utility model is: overcome the deficiency in prior art, provide a kind of have good
Hydrophilicity and corrosion resistant ability, skin-friction coefficient is minimum, and the abrasion of mould can be greatly reduced, and reduces punching oil and uses, improves
Rush wing speed, can effectively reduce production cost, the self-lubricating high antiseptic and hydrophilic aluminium foil of improve production efficiency.
This utility model solves its technical problem and be the technical scheme is that a kind of self-lubricating high antiseptic and hydrophilic aluminium foil,
Including aluminium foil layer, described aluminium foil layer upper surface is coated with epoxy resin anticorrosive coat, and described aluminium foil layer lower surface is then coated with
Lower epoxy resin anticorrosive coat, the upper surface of described upper epoxy resin anticorrosive coat is then coated with self-lubricating hydrophilic layer, described under
The lower surface of epoxy resin anticorrosive coat is then coated with lower self-lubricating hydrophilic layer, described upper self-lubricating hydrophilic layer and lower self-lubricating parent
Water layer is the acrylic resin modified layer of coating.
Further, upper epoxy resin anticorrosive coat and lower epoxy resin anticorrosive coat thickness are 0.4g/～0.6g/.
Further, upper self-lubricating hydrophilic layer and lower self-lubricating hydrophilic layer thickness are 1.6g/～2.4g/.
The beneficial effects of the utility model are: the self-lubricating high antiseptic and hydrophilic aluminium foil that this utility model provides, and have good
Hydrophilicity and corrosion resistant ability, skin-friction coefficient is minimum, and the abrasion of mould can be greatly reduced, and reduces punching oil and uses, carries
Height rushes wing speed, can effectively reduce production cost, improve production efficiency.
Brief description
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Self-lubricating hydrophilic layer on 3. times epoxy resin anticorrosive coats 4. of epoxy resin anticorrosive coat in figure 1. aluminium foil layer 2.

Specific embodiment
Presently in connection with accompanying drawing, this utility model is further described.These accompanying drawings are the schematic diagram of simplification only to show
Meaning mode illustrates basic structure of the present utility model, and therefore it only shows the composition relevant with this utility model.
A kind of self-lubricating high antiseptic and hydrophilic aluminium foil as shown in Figure 1, including aluminium foil layer 1, described aluminium foil layer 1 upper surface applies
It is covered with epoxy resin anticorrosive coat 2, described aluminium foil layer 1 lower surface is then coated with lower epoxy resin anticorrosive coat 3, described upper asphalt mixtures modified by epoxy resin
The upper surface of fat anticorrosive coat 2 is then coated with self-lubricating hydrophilic layer 4, and the lower surface of described lower epoxy resin anticorrosive coat 3 then applies
It is covered with lower self-lubricating hydrophilic layer 5, described upper self-lubricating hydrophilic layer 4 and lower self-lubricating hydrophilic layer 5 are the modified propylene of coating
Acid resin layer.
Preferably, upper epoxy resin anticorrosive coat 2 and lower epoxy resin anticorrosive coat 3 thickness are 0.4g/～0.6g/.On
Self-lubricating hydrophilic layer 4 and lower self-lubricating hydrophilic layer 5 thickness are 1.6g/～2.4g/.
In process of production, hydrophilic aluminium foil have face apply and primary coat point, face apply there is hydrophilic, primary coat has anti-corrosive properties.
The coefficient of friction of face painting therefore to be improved, then need using acrylic resin modified coating, make coating surface have hydrophilic
But also with lubricity, thus improving the friction level between aluminium foil and mould.In the case of not increasing thickness, using asphalt mixtures modified by epoxy resin
As bottom-coating, epoxy resin general chemical structure is two or more epoxide groups to fat, with other organic functionses
Group crosslink reaction formed insoluble there is the cancellated high polymer of three-dimensional, therefore epoxy resin is with respect to acrylic acid tree
Fat has more preferable chemical stability.In the more serious area of corrosive environment, chemical attack reaction acrylic resin relatively will delay
More slowly.
During production, first, using deionized water and degreasing agent, aluminium foil layer 1 surface Residual oil is removed before being coated with, solution temperature
For 40 DEG C～60 DEG C, then through cold and hot twice deionized water rinsing, dry it is ensured that aluminium foil layer 1 is subsequently coated with for 350 DEG C～400 DEG C
When with the combination degree of coating.Then, coating tension force 180kg～260kg, coating speed 80m/min, applicator roll speed 90r/ are set
Min, smoother roller speed 35r/min；Aluminium foil layer 1 upper and lower surface is respectively coated with upper epoxy resin anticorrosive coat 2 and lower epoxy resin is prevented
Rotten layer 3, carries out primary coat.Then, set primary coat drying temperature as 220 DEG C～240 DEG C, so that film is fully cured, lift adhesive force.
Then, setting coating thickness 2.0g/～3.0g/, face painting thickness 0.4g/～0.6g/, primary coat thickness 1.6g/～
2.4g/, contrast both sides, positive and negative, confirm no color differnece, holiday, upper epoxy resin anticorrosive coat 2 upper surface is applied and is covered with self-lubricating
Hydrophilic layer 4, the lower self-lubricating hydrophilic layer 5 to the coating of lower epoxy resin anticorrosive coat 3 lower surface, carry out face and apply modified acrylate resin layer
Operation.Finally, contrast both sides, positive and negative, confirm film no color differnece, no holiday.
The self-lubricating high antiseptic and hydrophilic aluminium foil being so designed that, coating consumes not to be increased, and antiseptic power cass tests 144h
R.no.9.5 level, theoretical antiseptic power lifts 4 times；In terms of rushing wing, 9.52mm aperture 8011 fin cannot break through 1 inch 9
Rush the wing limit, punching speed is low, and punching press oil consumption is high, and die wear is big.Using the high anti-corrosion parent of the self-lubricating of this utility model design
Water aluminium foil, can make aluminium foil surface coefficient of friction be reduced to less than 0.1, break through 1 inch 9 rush the wing limit, punching speed improves 20%,
Punching oil usage amount reduces 15%, and mould extends 6 months maintenance period, effectively reduces the production cost of a high pitch of fins two device product
And improve production efficiency, make a high pitch of fins two device product possess the working condition that routinizes, be provided simultaneously with the parent of conventional hydrophilic aluminium foil
Aqueouss and anti-corrosive properties, effectively improve production efficiency, reduce production cost.
Above-mentioned embodiment is only that technology design of the present utility model and feature are described, its object is to allow and is familiar with this skill
The personage of art will appreciate that content of the present utility model and is carried out, and can not limit protection model of the present utility model with this
Enclose, all equivalence changes made according to this utility model spirit or modification, all should cover in protection model of the present utility model
In enclosing.
