Description

A thermoplastic polymer film composite aluminum foil tape without lining paper

technical field

The utility model relates to an aluminum foil adhesive tape, in particular to an aluminum foil adhesive tape without backing paper. the

Background technique

At present, there are generally four types of aluminum foil tapes used for pipe insulation and for fixing condensation pipes in refrigerators, air conditioners, and freezers:

1. Aluminum foil tape with lining paper. The disadvantage of this kind of aluminum foil tape is that it needs to use lining paper. When using the lining paper, it needs to be torn off and discarded as garbage, which wastes resources, and the production cost is high, which is not environmentally friendly and causes waste.

2. Film-coated aluminum foil tape without backing paper. This product includes a plastic film layer, an intermediate adhesive layer, an aluminum foil layer and a primer layer. The intermediate adhesive layer needs to be glued by a rubber roller to connect the plastic film layer and the aluminum foil. layer, high production cost, complex production process, and the product is difficult to tear and inconvenient to use. the

3. Aluminum foil tape without backing paper, which uses a layer of silicone oil as a release agent on the aluminum foil layer. The disadvantage is that the silicone oil causes organic solvent pollution, and the thickness of the aluminum foil layer is thick, which greatly wastes aluminum foil resources and the strength of the product is insufficient. , easy to pull off. the

4. Aluminum foil tape with lining film is made of silicone oil-coated release paper or silicone oil-coated release film as the release layer, and then the adhesive layer is coated on the release layer, and then laminated with aluminum foil, or coated on the aluminum foil layer The adhesive layer is then compounded with the release layer. Since silicone oil is pre-coated on the film as a release agent, the entire production process is complicated and the cost is high. the

Contents of the invention

In order to overcome the deficiencies of the prior art, the utility model provides a thermoplastic polymer film composite aluminum foil adhesive tape without backing paper, which is resistant to tension, easy to tear, high in viscosity, simple in process and low in production cost. the

The technical solution adopted by the utility model to solve the technical problem is: a thermoplastic polymer film composite aluminum foil tape without backing paper, which is composed of a thermoplastic polymer film, an aluminum foil layer and an adhesive layer, wherein the aluminum foil layer is located in the middle layer, and the thermoplastic The polymer film is bonded to the aluminum foil layer by heating;

As a further improvement of the above scheme, the thickness of the thermoplastic polymer film is 4-100 μm;

Further, the thickness of the aluminum foil layer is 4-200 μm;

Further, the thickness of the adhesive layer is 2-200 μm;

The beneficial effect of the utility model is: the utility model does not use the lining paper, because the lining paper is thrown away as garbage during the use process, so the resource can be greatly saved and the production cost can be reduced. At the same time, the weight of the finished aluminum foil layer tape is also greatly reduced. In the utility model, one side of the thermoplastic polymer film and the aluminum foil layer is heated and bonded together by a heating roller to achieve the effect of release. Unwind and tear off the roll without stretching the tape. The finished product is very convenient for machine operation or manual operation.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described. the

Fig. 1 is the structural representation of the utility model. the

Detailed ways

Referring to Fig. 1, a thermoplastic polymer film composite aluminum foil tape without liner is composed of a thermoplastic polymer film 1, an aluminum foil layer 2 and an adhesive layer 3, wherein the aluminum foil layer 2 is located in the middle layer, and the thermoplastic polymer film 1 is heated The way is bonded together with the aluminum foil layer 2, reducing the use of the backing paper, because the weight of the backing paper is generally required to be more than 80g/cm2, in the same situation, the weight of the aluminum foil tape with the backing paper is heavier than the aluminum foil tape of the utility model , causing inconvenience to use or transportation. The volume of the aluminum foil tape with backing paper is 6 to 12 times that of the utility model, so the stacking area is large, and it is difficult to recycle. Compared with the utility model, the utility model saves resources and reduces production costs. the

The thermoplastic polymer film 1 has self-adhesiveness in a heated state, and the thickness of the thermoplastic polymer film 1 is 4-100 μm, and is closely bonded to the aluminum foil layer in a heated state, and can replace a part of the High-quality aluminum foil reduces costs and strengthens the strength of the aluminum foil layer to prevent it from being easily broken during stretching. the

The aluminum foil layer 2 is composed of aluminum foil, alloy aluminum foil or tin foil, and the thickness of the aluminum foil layer 2 is 4-200 μm. the

The thickness of the adhesive layer 3 is 2-200 μm, and the adhesive layer 3 can be one of water-based pressure-sensitive adhesive, oil-based pressure-sensitive adhesive, hot-melt adhesive, rubber, silica gel, flame-retardant adhesive or other high and low temperature adhesives. kind. the

The utility model does not use the lining paper, because the lining paper is thrown away as garbage in the process of use, so the resource can be greatly saved and the production cost can be reduced. At the same time, the weight of the finished aluminum foil layer 2 tape is also greatly reduced. In the utility model, the thermoplastic polymer film 1 and one side of the aluminum foil layer 2 are heated and bonded together by the heating roller 4 to achieve the release effect. The manufacturing process is simple, and the finished product has high tensile strength and is easy to tear—— It is easy to unwind and tear off from the tape without stretching the tape, and the finished product is very convenient for machine operation or manual operation. the

Of course, the utility model is not limited to the above-mentioned embodiments, as long as they achieve the technical effect of the utility model by basically the same means, they should all belong to the protection scope of the utility model. the
