Above-mentioned transparent high density polyethylene (HDPE) sheet is fitted on the sal plywood of thickness 12mm, and according to the regulation of JIS K 6253, the case hardness when using D type hardness tester meter to measure is 55.
And, Corona discharge Treatment is carried out on the two sides in the intermediate layer that obtains.
(making of decorating material for flooring)
On the primary coat face of the back side of above-mentioned cosmetic sheet, coated heat curable polyurethane resinae adhesive makes that the solid constituent amount is 8g/m
2, with the above-mentioned intermediate layer of its superimposed layer.Adopt woodburytype (face opposite) coating polyurethane-cellulosic resin solution on above-mentioned intermediate layer, make that the solid constituent amount is 2g/m with cosmetic sheet
2, form back side scratch coat.
Then, the back side scratch coat in the above-mentioned intermediate layer of fitting on the sal plywood of thickness 12mm is made decorating material for flooring.In applying, use polyurethane-modified ethene-vinyl acetate class emulsion binding agent (9g/ chi
2Wet).
According to the regulation of JIS K 6253, use D type hardness tester meter, the case hardness of the above-mentioned decorating material for flooring when above-mentioned cosmetic sheet one side is measured is 52.
Embodiment 2
Except using the thick coloured polypropylene film of 60 μ m to replace the above-mentioned resin sheet, adopt method similarly to Example 1, make decorating material for flooring.
Then, measure the surface strength of decorating material for flooring according to method similarly to Example 1.The case hardness of the decorating material for flooring that obtains is 59.
Comparative example 1
Manufacturing is according to the regulation of JIS K 6253, case hardness when measuring with D type hardness tester meter is that 78 thickness is the POLYCARBONATE SHEET of 400 μ m, except using this sheet material to replace above-mentioned intermediate layer to make the decorating material for flooring, adopt method similarly to Example 1 to make decorating material for flooring.
Then, measure the surface strength of decorating material for flooring according to method similarly to Example 1.The case hardness of the decorating material for flooring that obtains is 75.
Test example 1 (caster-resistant)
Use caster-resistant testing arrangement L6-O4 (shallow wild machinery production Co., Ltd. produce), the caster-resistant of the decorating material for flooring that obtains among embodiment 1 and the embodiment 2 is estimated.Evaluation procedure is as follows.That is, will be fixed on as the decorating material for flooring of tested object on the sample fixed station.Lift the castor fixed station with regulating handle, make 3 castors not contact with the surface of this decorating material for flooring.On the load platform, add that weight reaches the weight of 70kg then.Then, use the regulating handle increase to load on 3 loads on the castor.Setting rotary speed is the speed of 20rpm, carries out reverse rotation in per 5 minutes, rotates 1000 times, after 1000 rotations finish, rotates regulating handle, and the castor fixed station is lifted, and takes out the decorating material for flooring as tested object.
The cup depth of the decorating material for flooring that takes out is lower than 100 μ m.Thus, the decorating material for flooring that obtains among embodiment 1 and the embodiment 2 can be used for the place of requirement caster-resistant effectively.
