Comparative example 1, compound film material C1'：By the A3 of 100 ± 10 parts by weight and B9 of 70 parts by weight under the conditions of 40 DEG C of temperature It is uniformly mixed, coating abutted equipment is flexible package slow curing type list coater unit equipment (Sinstar China WRJ 15 1000A), binding temperature is 40 DEG C, and spread is 1.0~2.5g/m2, device rate is 50~400m/min, and bonding structure is Bidirectional stretching polypropylene film is bonded cast polypropylene film, and machine is without initial bonding strength under the compound thin material C1' posted, and winding is easily Side is run in dislocation, 4~8 it is small when after could carry out sentencing at the beginning of exterior quality, its T-shaped peel strength could be measured by curing 1~2 day, be reached More than 1.2N/15mm peel strengths, can just be cut and other subsequent handlings.If after curing 1~2 day, peel strength is not It is up to standard accurate or even too low layering can be caused to dial from high volume scrapping, cause enterprise's writing loss.With the compound thin material of embodiment 1 C1 compares, and flexible package enterprise (first mixes the first component and be coated in two components) using traditional slow curing type technique, it need to cure 1~ Reach within 2 days cutting process peel strength demand, cause turnover stock it is excessively high, cost is substantially increased, and because 4~8 it is small when after It can carry out exterior quality just to sentence, bad order causes high-volume to scrap, this still can not be comprehensive for general flexible package color printing enterprise Where the reason for traditional solvent-free process.No-solvent polyurethane solid according to the invention can carry out product in 10 minutes Matter is just sentenced, and measures its peel strength within 120 minutes, and high-volume is effectively avoided to scrap, and turnover stock is solvent-free far below general tradition Technique.
Comparative example 2, compound film material C2'：By the A1 (the first component of low surface tension) of 100 ± 10 parts by weight in temperature 40 It is spread evenly across under the conditions of DEG C on bidirectional stretching polypropylene film (low surface tension substrate) printing surface, in addition by 70 parts by weight B1 (the second component of low surface tension) is spread evenly across cast polypropylene film (low surface tension base under the conditions of 40 DEG C of temperature Material) on, coating abutted equipment is the double coater unit equipment (Sinstar China WRJK i5 1300A) of flexible package quick-dry type, Binding temperature is 40 DEG C, and spread is 1.0~2.5g/m2, device rate is 50~400m/min, because of the first component and second group The weight ratio difference of part is too big, causes the first component, the second component coating thickness difference too big, and easily in fitting It causes to mix uneven, and then ultimately causes glue and do not do phenomenon, generate and large quantities of scraps adhesive product.
Comparative example 3, compound film material C3'：By the A4 of 100 ± 10 parts by weight and the B10 of 60 parts by weight in temperature 60 C condition Lower to be uniformly mixed, coating abutted equipment is flexible package slow curing type list coater unit equipment (Sinstar China WRJ 15 1000A), binding temperature is 60 DEG C, and spread is 1.0~2.5g/m2, device rate is 50~400m/min, and bonding structure is Bidirectional stretching polypropylene film (low surface tension substrate) fitting cast polypropylene aluminizer (high surface tension base material), posts Compound thin material C3' cure and occur within 1~2 day significantly seriously aluminizing transfer phenomena.Compared with 11 compound thin material C11 of embodiment, according to Design can be separated with the second component according to the first component in the no-solvent polyurethane solid of the present invention, with the first of low surface tension Component is coated on the bidirectional stretching polypropylene film (the first base material) of low surface tension, and the second component of high surface tension is applied Cloth is then bonded on the cast polypropylene aluminizer (the second base material) of high surface tension, efficiently avoids aluminizing again The generation of transfer phenomena.
Comparative example 4, compound film material C4'：The A3 (low surface tension) of 100 ± 10 parts by weight is (low with the B9 of 70 parts by weight Surface tension) it is uniformly mixed under the conditions of 40 DEG C of temperature, coating abutted equipment is flexible package slow curing type list coater unit equipment (15 1000A of Sinstar China WRJ), binding temperature are 40 DEG C, and spread is 1.0~2.5g/m2, device rate 50 ~400m/min, bonding structure are bonded polyethylene film (low surface tension substrate) for polyester film (high surface tension base material), The compound film material C4' posted is cured 1~2 day and is measured its T-shaped peel strength, only below 0.3N/15mm peel strengths, is bonded Fastness deficiency causes high-volume to be scrapped, the reason for this is that traditional solvent-free process is coated for first mixing, the first component, the second component It can not separate and design, for this example, effective wetting Bing then high surface tensions are intended to the polyurethane adhesives of low surface tension Polyester film, the phenomenon that be easy to causeing moistening badness and too low peel strength.Compared with the compound film material C5 of embodiment 5, No-solvent polyurethane solid of the present invention is bonded again to be first coated with, and the first component, the second component separately design, with high surface The polyester film surface of first component effective wetting Bing of power then high surface tensions is effective with the second component of low surface tension The polyethylene film surface of Bing then low surface tensions is soaked, 120 minutes after fitting, tests its compound film material peel strength immediately Up to more than 1.8N/15mm.Yields according to compound film material of the present invention is high, and risk is far below traditional handicraft.
Table two lists in 1-15 of the embodiment of the present invention compound thin material C1'~C4' in compound thin material C1~C15, comparative example 1-4 The survey of the species of middle the first base material, the species of the second base material, the species of the first component, the species, T-shaped peel strength of the second component The test result of test result (embodiment is all the test result of 120 minutes after fitting) and finished appearance, wherein, it is low to refer to table Face tension is relatively low, and height refers to that surface tension is higher, refers to that it uses the first component, the second component first to mix the tradition being coated slowly Solvent process, T-shaped peel strength is tested according to ASTM D1876, and the acceptance condition that is judged as of finished appearance is detection There is not the defects of orange peel, fisheye, white point, bubble, saturating aluminium, tunnel in composite membrane.
Although the present invention is disclosed above with embodiment, however, it is not to limit the invention, any to be familiar with this skill Person, without departing from the spirit and scope of the present invention, when can be used for a variety of modifications and variations, therefore protection scope of the present invention is worked as Subject to appended claims institute defender.
