Problems solved by technology

But above-mentioned patent still has shortcoming, the one, although have saved release paper, because any kind of film in polyethylene (PE) or polyester (PET) or biaxially stretched polypropylene (BOPP) is made earlier One side of the surface is compounded to the surface of the aluminum foil substrate coated with a composite adhesive layer, specifically see the description of step C of the patent, and then the other side of the aforementioned film or the back is coated with a treatment agent
Therefore, the production process is relatively cumbersome; second, because the aforementioned PE or PET or BOPP film is compounded on the surface of the aluminum foil substrate, the high temperature resistance of the finished adhesive tape is restricted; Large amount of raw materials and high production costs

Abstract

The invention relates to a method for manufacturing aluminium foil adhesive tape for cementing refrigerating installations such as a condenser pipe of a refrigerator or a refrigerator and the inner container of the box body of a refrigerator or the outer wall of the inner container of the refrigerator body of a refrigerator, the method comprises the following steps: choosing aluminium foil material, coating silicone oil on the surface one side of aluminium foil substrate, and drying by a drying channel as soon as coating, placing in ageing effect under normal temperature after getting out of a drying channel and being winded up, and coating pressure-sensitive adhesive on the surface of the other side of the aluminium foil substrate after placing in aging effect, and dying by a drying channel as soon as coating, winding up, parting cut, and getting aluminium foil adhesive tape end products. The manufacturing method has the advantages that since thin film and aluminium foil substrate are not needed to composite, therefore the method can not be restricted by high temperature resistance shortage, which is beneficial for guaranteeing high-temperature resisting property of products, saving raw material, and shortening manufacture process, the combining rate of adhesive tape products which are got by the method and polyurethane foaming material can reach100%, stripping strength can reach16-20N / cm, and persistent adhesivity time can reach more than 1000hs.

Description

technical field [0001] The invention relates to a method for making an aluminum foil adhesive tape, more specifically, a method for bonding a condensation pipe of a refrigeration device such as a refrigerator or a freezer to the inner liner of a refrigerator or to the outer wall of the inner liner of a freezer The production method of aluminum foil adhesive tape. Background technique [0002] Chinese patent authorization announcement number CN1208416C discloses a processing method of aluminum foil adhesive tape. Deficiencies exhibited by insulating aluminum foil adhesive tape. Regarding the lack of these two adhesive tapes, since the objective evaluation has been made in the background technology column of the above-mentioned patent, the applicant will not repeat them. But above-mentioned patent still has shortcoming, the one, although have saved release paper, but because any one film in polyethylene (PE) or polyester (PET) or biaxially oriented polypropylene (BOPP) One ...
