[0001] The utility model relates to the technical field of packaging materials, in particular to a PE composite hose packaging material based on a solvent-free bonding technology. Background Technique

[0002] Polyethylene (PE for short) is a thermoplastic resin obtained by polymerizing ethylene. A hose is an important component in modern industry. Hoses are mainly used as wire and cable protection tubes for wires, cables, and automated instrument signals, as well as civil shower hoses. Plastic composite hoses have become one of the main packaging varieties for cosmetics, medicine, and food due to their convenience, economy, and good hygiene.

[0003] The existing Chinese patent document CN202120049601.7 discloses a PE hose with good heat resistance, including a base tube. An insulating layer is fixedly connected to the inner wall of the base tube, an anti-scaling coating is arranged on the inner wall of the insulating layer, an anti-deformation layer is fixedly connected to the surface of the base tube, a flame-retardant layer is fixedly connected to the surface of the anti-deformation layer, and a wear-resistant layer is fixedly connected to the surface of the flame-retardant layer. By setting the insulating layer, the heat resistance of the PE hose with good heat resistance is significantly improved, so that when the PE hose is used in occasions where high temperature resistance is required, the good performance of the PE hose can be exerted, thereby improving the practicability of the PE hose and better serving users. By setting the wear-resistant layer, the wear resistance of the PE hose is improved, and it has good anti-breakdown performance, solving the shortcoming that the PE hose is fragile, making the performance of the PE hose better and extending the service life of the PE hose.

[0004] However, there are certain defects in the use of the above patent. When the hose needs to transport liquid, sometimes there are requirements for the temperature of the liquid, and heat preservation or cold preservation is required. However, most hoses have poor heat preservation / cold preservation effects, and the temperature of the transported liquid cannot meet the requirements.

[0005] Therefore, a PE composite hose packaging material based on a solvent-free bonding technology is proposed here to solve the above problems. Content of the Utility Model

[0006] In order to overcome the deficiencies of the prior art, the utility model provides a PE composite hose packaging material based on a solvent-free bonding technology.

[0007] The utility model is realized by adopting the following technical scheme:

[0008] A PE composite hose packaging material based on a solvent-free bonding technology includes a base layer, which is divided into an outer layer and an inner layer. Both the outer layer and the inner layer are made of linear low-density polyethylene. A heat preservation layer is arranged outside the base layer for heat preservation of the hose.

[0009] The heat insulation layer is made of heat insulation cotton. The heat insulation layer includes a body. An adhesive part is provided on the side of the body. The thickness of the adhesive part is less than that of the body. A magic tape is provided on the body. The magic tape is divided into a sub-surface and a mother-surface. The sub-surface is fixed on the front of the body, and the mother-surface is arranged on the back of the body. The mother-surface covers the surface of the body except for the adhesive part;

[0010] An adhesive layer is provided on the back of the adhesive part.

Modified epoxy resin glue is coated on both the front and back sides of the aluminum foil. The outer layer and the inner layer are respectively adhered to the front and back sides of the aluminum foil.

[0013] Through the above technical solution, the addition of aluminum foil not only improves the barrier performance of the packaging material, prevents the penetration of light, gas and moisture, but also enhances the structural strength of the packaging material.

[0014] An anti-sticking coating is provided on the inner wall of the base layer. The anti-sticking coating is adhered to the inner wall of the base layer through modified epoxy resin glue.

[0015] Through the above technical solution, it effectively prevents the adhesion of the content on the inner wall of the hose, which is convenient for cleaning and repeated use.

[0016] A wear-resistant layer is provided on the outside of the base layer. The wear-resistant layer is adhered to the outer peripheral wall of the base layer through modified epoxy resin glue.

[0017] Through the above technical solution, the wear resistance of the packaging material is improved, and the service life is prolonged.

[0028] The following further describes the present utility model with reference to the accompanying drawings.

[0029] As Figures 1 to 4 shown, a PE composite hose packaging material based on a solvent-free bonding technology includes a base layer 3. The base layer 3 is divided into an outer layer 31 and an inner layer 32. Both the outer layer 31 and the inner layer 32 use linear low-density polyethylene as the constituent material and both use linear low-density polyethylene (LLDPE) as the main material to ensure the basic physical properties and chemical stability of the packaging material. A thermal insulation layer 5 is provided outside the base layer 3. The thermal insulation layer 5 is used for the heat preservation of the hose;

[0030] The thermal insulation layer 5 is made of thermal insulation cotton. The thermal insulation layer 5 made of thermal insulation cotton has excellent heat insulation effect. The thermal insulation layer 5 includes a body 51. A bonding part 52 is provided on the side of the body 51. The thickness of the bonding part 52 is less than that of the body 51. The thickness of the bonding part 52 is less than that of the body 51 to facilitate reducing material waste when connecting with other components or structures and at the same time ensure the firmness of the connection. A magic tape is provided on the body 51. The magic tape is divided into a sub-surface 53 and a mother surface 54. The sub-surface 53 is fixed on the front of the body 51. The mother surface 54 is arranged on the back of the body 51. The mother surface 54 fills the surface of the body 51 except for the bonding part 52. This design facilitates the quick installation and disassembly of the thermal insulation layer 5, improves the flexibility of use, improves the packaging efficiency, and reduces the maintenance cost;

[0031] A bonding layer 55 is provided on the back of the bonding part 52.

[0032] A functional layer 33 is provided between the outer layer 31 and the inner layer 32. The functional layer 33 is made of aluminum foil, and both sides of the aluminum foil are coated with a modified epoxy resin adhesive 2. The outer layer 31 and the inner layer 32 are respectively bonded to the front and back sides of the aluminum foil.

[0033] An anti-sticking coating 1 is provided on the inner wall of the base layer 3. The anti-sticking coating 1 is bonded to the inner wall of the base layer 3 through a modified epoxy resin adhesive 2. This device uses a solvent-free adhesive such as the modified epoxy resin adhesive 2 to achieve firm bonding between layers through chemical reactions. This technology avoids the use and emission of solvents and protects the environment.

[0034] A wear-resistant layer 4 is provided outside the base layer 3. The wear-resistant layer 4 is bonded to the outer peripheral wall of the base layer 3 through a modified epoxy resin adhesive 2. The setting of the wear-resistant layer 4 improves the wear resistance of the packaging material and extends the service life.

[0035] The working principle of the present utility model is as follows: When in use, when heat preservation for the hose is required, the heat preservation layer 5 is installed on the hose. The bonding part 52 provided on the heat preservation layer 5 bonds the heat preservation layer 5 made of heat preservation cotton to the base layer 3 through the solvent-free modified epoxy resin adhesive 2. The bonding part 52 on the heat preservation layer 5 contacts the base layer 3 and achieves firm bonding through the bonding layer 55. At the same time, the magic tape on the heat preservation layer 5 can be quickly installed and disassembled as needed, improving the flexibility of use.
