Description

The TPU materials and rainbow illusion-colour being bonded online for rainbow illusion-colour thin-film sheet are thin Film sheet
Technical field
The present invention relates to chemical field, specifically, is related to a kind of TPU being bonded online for rainbow illusion-colour thin-film sheet Material and rainbow illusion-colour thin-film sheet.
Background technology
With the improvement of living standards, people begin look for the thing that some especially attract eyeball, some top grades have The products such as special decorative effect shoes, bag, packaging material, ornament materials enter our sight, particularly material in recent years The development in material field so that these new materials constantly emerge in large numbers, such as PET fittings, and PVC fittings have the unreal of colorful effect Color film or sheet material enter our sight, constantly hit our eyeball, but the illusion-colour diaphragm of these PET or PVC fittings Material, itself does not have elasticity, and wear-resisting property is also poor, also poor to the adaptability of the use environment of high/low temperature, and These materials mosts use after paste technique processing, during can discharge VOC, do not meet environment-friendly materials development trend.For this reason, open Hair one kind meets environmental requirement, and the rainbow illusion-colour thin-film sheet of excellent performance is imperative.
Existing rainbow illusion-colour thin-film sheet generally uses following material and process:1. PET or PVC fitting illusion-colours are thin Film, these materials it is elastic poor, easily there is scratch in wear-resisting scratch resistance;TPU is bonded using adhesive, can produce VOC.2. using molten Formulation adhesive or Hot-melt adhesive (being dried after hot melt adhesive dissolving), can produce substantial amounts of VOC during fitting.③ Although rainbow illusion-colour film is especially dazzled, using the product of this technique fitting, appearance transparent is poor, and fantasy coloured effect also can be big It is big relatively low, influence beauty.
The illusion-colour film of TPU fittings at present is using solvent type adhesive or Hot-melt adhesive (after hot melt adhesive dissolving Drying), substantial amounts of VOC can be produced during fitting, and using the product of this technique fitting, appearance transparent is poor, unreal Color effect also can be significantly relatively low, influences beauty, and the fastness of attachment is poor.
The content of the invention
The object of the present invention is to provide the rainbow illusion-colour thin-film sheet that a kind of VOC emission is low, combined strength bination is good, beautiful;Together When also disclose the key material of the sheet material-be used for the TPU materials that rainbow illusion-colour thin-film sheet is bonded online;Using TPU materials Material adds the wear-resisting scratch resistance performance of composite material, and low temperature resistant ageing-resistant performance, adds the experience effect of user, add Economic benefit.
Specifically, the technical scheme is that:
A kind of TPU materials being bonded online for rainbow illusion-colour thin-film sheet, the TPU materials include 80~95wt% 85~95A of hardness polyester-type or the tackifying resin of polyether-type TPU particles and 3~5wt%.
The present invention is matched somebody with somebody using the polyester-type or the tackifying resin of polyether-type TPU particles and 3~5wt% of 85~95A of hardness The reason for conjunction, is that the polyester-type or polyether-type TPU particles of 85~95A of hardness can ensure preferable feel and heat resistance, At the same time beneficial to the preferable membrane effect of holding in Screw Extrusion.The effect of tackifying resin is, matches somebody with somebody with TPU particles Close, improve the combination effect with rainbow film, be allowed to reach integrated use feeling during sense of touch and use.
In the above-mentioned TPU materials for being used for rainbow illusion-colour thin-film sheet and being bonded online, the tackifying resin is EastmanResin2336 tackifying resins.Certainly, in the present solution, other tackifying resins can be used, it is transparent good to meet, And required well with TPU compatibilities.At present only with this tackifying resin.For example, Exxon Mobil high-performance tackifying resin Escorez5320 high temperature resistants tackifier, transparent tacking agent auxiliary agent, the colourless tackifying assistant of hyperviscosity tackifying resin.
In the above-mentioned TPU materials for being used for rainbow illusion-colour thin-film sheet and being bonded online, the TPU materials further include Bright 1~3wt% of lubrication prescription.
In the above-mentioned TPU materials for being used for rainbow illusion-colour thin-film sheet and being bonded online, the TPU materials further include 1 The anti-reflection master batch of~1.5wt%.
In the above-mentioned TPU materials for being used for rainbow illusion-colour thin-film sheet and being bonded online, the TPU materials further include 10 The fire-retardant master granule of~15wt%.
In the above-mentioned TPU materials for being used for rainbow illusion-colour thin-film sheet and being bonded online, the TPU materials further include 3 The antistatic master granule of~5wt%.
In the above-mentioned TPU materials for being used for rainbow illusion-colour thin-film sheet and being bonded online, the TPU materials further include 6 The anti-UV master batches of~8wt%.
Meanwhile the invention also discloses a kind of rainbow illusion-colour thin-film sheet, including rainbow film and be arranged on rainbow film Under the TPU membrane that shows;The TPU membrane is made of TPU materials as described above.
In above-mentioned rainbow illusion-colour thin-film sheet, the thickness of the rainbow illusion-colour thin-film sheet is 30~2000um.
In above-mentioned rainbow illusion-colour thin-film sheet, the thickness of the rainbow film is PET the or PVC materials of 16um~26um The rainbow film of matter.
Beneficial effect:
The TPU film produced using the TPU film material, it is possible to achieve the online fitting of direct illusion-colour TPU film sheet material, subtracts The discharge of VOC is lacked, the TPU illusion-colour thin-film sheet appearances of fitting are gorgeous, considerably increase production efficiency, reduce and be produced into This, using the TPU materials of special formulation, the illusion-colour TPU film sheet material attachment fastness after fitting is big, and fastness is good, using TPU materials Material adds the wear-resisting scratch resistance performance of composite material, and low temperature resistant ageing-resistant performance, adds the experience effect of user, add Economic benefit.
