Abstract
The invention provides a kind of novel hot melt cloth base adhesive tape and coating process thereof, when being coated with, first at the one side coating layer of polyethylene film of substrate, then on polyethylene film coating release agent; Then apply one deck primer at the another side of substrate, finally apply an aspect glue again on primer surface.The present invention passes through glue coating adhesion coating at twice, makes the hot melt cloth base adhesive tape produced in use not easily occur coming unstuck, overflowing glue phenomenon.
Description
Technical field
The present invention relates to a kind of hot melt cloth base adhesive tape and coating process thereof, particularly relate to a kind of hot melt cloth base adhesive tape and coating process thereof of twice glue coating adhesion coating.
Background technology
Hot melt cloth base adhesive tape production process is in the market: first in the one side coating PE film of gauze base material, then be coated with parting agent on PE film, is coated with one deck hot melt glue afterwards at the another side of gauze base material.
The adhesive tape produced of this mode of production is reticulated porous structures on the one hand due to gauze used, make be coated with hot melt glue time must reach the hole that higher Amount of spread just can fill up gauze, on the other hand in order to make adhesive tape have good viscosity, the Amount of spread that same needs are very high, approximately the glue quantity of every square metre reaches about 100g.In addition glue is with SIS and SBS for material of main part, and the cost of this material is higher, and in production process, Amount of spread is larger, and production efficiency is lower.
Moreover usual hot melt adhesive is with SIS and SBS for material of main part, and strong not to the degree of adhesion of PE film, the phenomenon of coming unstuck in use easily appears in the adhesive tape produced.
For above-mentioned defect, urgent need a kind of brand-new hot melt cloth base adhesive tape of invention and coating process thereof solve the deficiencies in the prior art.
Summary of the invention
The object of the present invention is to provide a kind ofly in use not easily to come unstuck, the hot melt cloth base adhesive tape of the glue that overflows and coating process.
To achieve these goals, this application discloses a kind of hot melt cloth base adhesive tape coating process, specifically comprise the following steps:
A, one side coating layer of polyethylene film in substrate, then on polyethylene film coating release agent;
B, apply one deck primer at the another side of substrate, finally apply an aspect glue again on primer surface;
Each weight percentages of components of described primer layer is: unformed polyolefine 10-20%, thermoplastic elastomer 0-10%, softening oil 15-25%, resin 40-50%, oxidation inhibitor 0.5-1.5%, stopping composition 5-15%, and face glue-line is melt pressure sensitive glue,
The glue application amount of described primer layer and face glue-line is 50 grams/m.
As a further improvement on the present invention, described substrate is gauze.
To achieve these goals, disclosed herein as well is a kind of hot melt cloth base adhesive tape made according to aforesaid hot melt cloth base adhesive tape coating process, described hot melt cloth base adhesive tape comprises release layer, PE layer, substrate, primer layer and face glue-line successively from one side surface to opposite side surface.
As a further improvement on the present invention, described gauze is reticulated porous structures.
The present invention compared with prior art has following beneficial effect:
The present invention passes through glue coating adhesion coating at twice, makes the hot melt cloth base adhesive tape produced in use not easily occur coming unstuck, overflowing glue phenomenon.
Accompanying drawing explanation
Fig. 1 is the structural representation of hot melt cloth base adhesive tape of the present invention.
Embodiment
For enabling above-mentioned purpose, the feature and advantage of the application more become apparent, below in conjunction with the drawings and specific embodiments, the application is described in further detail.
Present embodiment provides a kind of hot melt cloth base adhesive tape coating process, specifically comprises the following steps:
A, one side coating layer of polyethylene film in substrate, then on polyethylene film coating release agent;
B, apply one deck primer at the another side of substrate, finally apply an aspect glue again on primer surface.
The hot melt cloth base adhesive tape that present embodiment also provides the hot melt cloth base adhesive tape coating process described in a kind of basis to make, described hot melt cloth base adhesive tape comprises release layer 1, PE layer 2, substrate 3, primer layer 4 and face glue-line 5 successively from one side surface to opposite side surface.Wherein said substrate 3 is gauze, and gauze is reticulated porous structures, and described glue-line 5 is melt pressure sensitive glue.Each weight percentages of components of described primer layer 4 is: unformed polyolefine 10-20%, thermoplastic elastomer 0-10%, softening oil 15-25%, resin 40-50%, oxidation inhibitor 0.5-1.5%, stopping composition 5-15%.
The feature of described hot melt cloth base adhesive tape coating process is, gauze one side is after coating polyethylene film and parting agent, one deck primer is first coated with at the another side of gauze, again at primer surface coated one aspect glue, in described hot melt cloth base adhesive tape coating process, single Amount of spread is significantly reduced to about 50 grams/m, with the Amount of spread of existing 100 grams/m, decreases fully about half.In addition, described hot melt cloth base adhesive tape coating process can realize continuous seepage on the coating apparatus of two coating head, and under the temperature condition of 160 ± 20 DEG C, application rate can improve nearly one times than existing coating technique.
Compared with the coating technique usually adopted, in hot melt cloth base adhesive tape coating process of the present invention, the coating of adhesive layer is divided into twice coating, when designing glue formula, the composition of primer and face glue can carry out distinctiveness design.Because primer more lays particular emphasis on the bonding with base material, the unformed polyolefine higher with polyethylene adhesive degree can be selected to substitute SIS and SBS, so just can solve the degumming problem that adhesive tape in use occurs, primer does not directly contact with adherend simultaneously, the terpine resin that the petroleum resin fictitious hosts that can price be used in a large number lower is higher, and suitably increase cheap stopping composition (as calcium carbonate).So both improve tape performance and again reduce product cost.
Although be example object, disclose the preferred embodiment of the present invention, but those of ordinary skill in the art will recognize, when not departing from scope and spirit of the present invention disclosed in appending claims, various improvement, increase and replacement are possible.
