Filler, is carbon black or white carbon black, and the filler accounts for the 22% of overall amount of resin, packing material size≤4 μm；
Dispersing agent, is polyethylene glycol, and the dispersing agent accounts for the 2% of overall amount of resin；
Defoaming agent, high temperature defoaming agent, the defoaming agent account for the 1% of overall number quality.
As shown in Fig. 2, the preparation method of above-mentioned ultrathin composite one-faced tapes, is made by following steps,
1) prepare base membrane layer 1: choosing bidirectional stretching polypropylene film, unreel, successively by 150 mesh, 150 mesh, 175 mesh, The specific net roll one-pass molding of 175 purposes, is made base membrane layer 1, and 1 thicknesses of layers of base membrane layer is 12 ± 1 μm；
2) it prepares printing layer 2: one layer of ink being coated in 1 first surface of base membrane layer using rubber roller, is through temperature 75 DEG C of drying tunnel, intake 60%, exhausting amount are 75%, and printing layer 2 is made；The ink is uniformly dispersed, white without obviously leaking And bulky grain agglomerate, glossiness fluctuate within ± 0.3；The ink stirs 30min through 1000~1200r/min, and uses The filtering of 300 mesh filter screens is made, and 2 thicknesses of layers of printing layer is 3 ± 1 μm；
3) it prepares adhesive layer 3: will include that the sheet EVA resin glue film of Surface Modification of Magnesium Hydroxide by Stearic Acid is adhered to step 2) 2 surface of printing layer made from；Gluing, the rubber roller requirement are carried out to the sheet EVA resin glue film using precision funny knife Shore hardness is between 60~70 °, and institute's gluing is the tackifying resin of the grain of frosted containing magnesium hydroxide, and the tackifying resin is rubber, The magnesium hydroxide frosted grain partial size is 400 μm；
4) ultrathin composite one-faced tapes are prepared: the EVA resin glue film containing Surface Modification of Magnesium Hydroxide by Stearic Acid is attached at step Rapid 3) products obtained therefrom surface is placed on drying in 110 DEG C of drying tunnels, and Yu Suoshu EVA resin film surface is bonded release film, is made super Thin compound one-faced tapes；
Wherein, stearic acid mass percentage is 6% in the Surface Modification of Magnesium Hydroxide by Stearic Acid, the stearic acid modified hydrogen It is 6% that magnesia, which accounts for EVA resin glue film mass percent,.
Net roll surface described in step 1) sets the angle of 120 ° of engraving needles engraving as 45 ° of diamond shape ink cell, and the space of a whole page is uniform, net Chromium plating again is carved after version copper facing.
To band 4 one-faced tapes of protective film obtained by above three embodiments carry out extension test, anti-flammability is tested and old Change test:
As seen from the above table, the anti-flammability of embodiment 1 is lower than 2 product of embodiment, this is because added in 2 product of embodiment Flame retardant amount increases；The elongation at break of embodiment 1 is less than 2 product of embodiment, this is because frosted grain partial size increases certain journey The mechanical property of product is affected on degree；In burn-in test, the ageing-resistant performance of 2 product of embodiment is most excellent, on the one hand fire-retardant A large amount of presence of agent can absorb a part of heat, and 2 high temperature defoaming agent of printing layer also can guarantee the stability of product；Another party Face, 1 selection of base membrane layer and thickness design are more resistant to aging, and part improves elongation at break；And it can be seen that by upper table Tensile property, flame retardant property and the ageing-resistant performance of commercially available one side glue are weaker than properties of product disclosed in this invention.
Although the embodiments of the present invention have been disclosed as above, but its is not only in the description and the implementation listed With.It can be applied to various suitable the field of the invention completely.It for those skilled in the art, can be easily Realize other modification.Therefore without departing from the general concept defined in the claims and the equivalent scope, the present invention is simultaneously unlimited In specific details and legend shown and described herein.
