Abstract
The utility model provides a novel hot melt duct tape which sequentially comprises a release layer, a PE (polyethylene) layer, a substrate, a bottom adhesive layer and a surface adhesive layer from the surface of one side to the surface of the other side of the hot melt duct tape. By coating the adhesive layers twice, production cost is greatly reduced, and the hot melt duct tape is not easy to degum during use.
Description
Technical field
The utility model relates to a kind of hot melt cloth base adhesive tape, relates in particular to a kind of hot melt cloth base adhesive tape of twice glue coating adhesion coating.
Background technology
Hot melt cloth base adhesive tape production process in the market is: first the one side at the gauze base material applies PE film, is coated with parting agent at the PE film again, afterwards at another side coating one deck hot melt glue of gauze base material.
The adhesive tape one side that this mode of production is produced is owing to the mesh structural porous structure that is of used gauze, so that be coated with hot melt glue the time must reach the hole that higher Amount of spread just can be filled up gauze, on the other hand in order to make adhesive tape have good viscosity, need equally very high Amount of spread, approximately every square metre glue consumption reaches about 100g.Glue is take SIS and SBS as material of main part in addition, and the cost of this material is higher, and in the production process, Amount of spread is larger, and production efficiency is lower.
Moreover usually hot melt adhesive is take SIS and SBS as material of main part, and is strong not to the degree of adhesion of PE film, and the phenomenon of coming unstuck in use easily appears in the adhesive tape of producing.
For defects, be badly in need of a kind of brand-new hot melt cloth base adhesive tape of invention and solve the deficiencies in the prior art.
The utility model content
The purpose of this utility model is to provide a kind of novel hot melt cloth base adhesive tape of coming unstuck of in use being difficult for.
To achieve these goals, the application discloses a kind of novel hot melt cloth base adhesive tape, and 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 further improvement of the utility model, described substrate is gauze.
As further improvement of the utility model, described gauze is mesh structural porous structure.
As further improvement of the utility model, described glue-line is hot-fusible pressure-sensitive adhesive water.
The present invention compared with prior art has following beneficial effect:
The utility model greatly reduced production cost, and the hot melt cloth base adhesive tape in use is not prone to degumming phenomenon by twice glue coating adhesion coating.
Description of drawings
Fig. 1 is a kind of structural representation of novel hot melt cloth base adhesive tape.
Embodiment
For above-mentioned purpose, the feature and advantage that make the application can become apparent more, below in conjunction with the drawings and specific embodiments the application is described in further detail.
Present embodiment provides a kind of novel hot melt cloth base adhesive tape (as shown in Figure 1), and 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 mesh structural porous structure, and described glue-line 5 is hot-fusible pressure-sensitive adhesive water.
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 coating process of novel hot melt cloth base adhesive tape specifically may further comprise the steps:
A, apply layer of polyethylene film, again coating release agent on polyethylene film in the one side of substrate 3;
B, apply one deck primer at the another side of substrate 3, apply again at last an aspect glue on the primer surface.
The coating process characteristics of hot melt cloth base adhesive tape are, the gauze one side is behind coating polyethylene film and parting agent, another side at gauze is coated with first one deck primer, again at primer surface coated one aspect glue, in the coating process of described hot melt cloth base adhesive tape, the single Amount of spread significantly is reduced to approximately 50 g/ms, and the Amount of spread with existing 100 g/ms has reduced about half fully.In addition, the coating process of described hot melt cloth base adhesive tape can be realized producing continuously at the coating apparatus of two coating heads, and under the temperature condition of 160 ± 20 degree, gluing speed can improve nearly one times than existing coating technique.
Compare with a coating technique of common employing, the coating process of described hot melt cloth base adhesive tape is divided into twice coating with the coating of adhesive layer, and when the design glue formula, the composition of primer and face glue can carry out the distinctiveness design.Because primer more lays particular emphasis on bonding with base material, can select unformed polyolefine alternative SIS and the SBS higher with the polyethylene degree of adhesion, so just can solve the degumming problem that adhesive tape in use occurs, primer does not directly contact with adherend simultaneously, can use in a large number the lower petroleum resin of price to substitute the higher terpine resin of price, and suitably increase cheap stopping composition (such as calcium carbonate).So not only improve tape performance but also reduced product cost.
Although be the example purpose, preferred implementation of the present utility model is disclosed, but those of ordinary skill in the art will recognize, in the situation that do not break away from by the disclosed scope and spirit of the present utility model of appending claims, various improvement, increase and replacement are possible.
