Problems solved by technology

[0003] The existing release agent is to dissolve the active ingredient in an organic solvent such as: toluene, cyclohexanone, etc. and mix evenly. The release agent made by this method is very easy to separate or separate out after being placed for a long time. The use effect will be greatly reduced, which will bring great difficulty and high cost to the storage and transportation of the release agent; at the same time, the organic solvents used in it all have highly toxic properties, which will pollute the environment and the operators during the production process. The health hazard is extremely serious; the downstream users of this type of release agent need high-temperature drying to remove the solvent, which once again brings high harm to the environment and the health of operators

Abstract

The invention discloses a preparation method of a release agent emulsion for an aluminum foil adhesive tape, which belongs to the field of release agent preparation. The main problem to be solved by the invention is that the existing release agent is prepared by dissolving active ingredients in a toxic organic solvent and uniformly mixing; the release agent prepared by the method is extremely easyto layer or separate out after being placed for a long time, the use effect of the release agent is greatly reduced, great difficulty and high cost are brought to storage and transportation of the release agent, and the environment and the health of operators are seriously damaged. The oxidized polyethylene wax, paraffin and rosin are melted and evenly mixed, saponification and emulsification areconducted in sequence, the emulsion stability is improved, and the release agent emulsion for the aluminum foil adhesive tape is non-toxic, difficult to volatilize, easy to produce and not prone to layering.

Description

technical field [0001] The invention discloses a method for preparing a release agent emulsion for an aluminum foil tape, which belongs to the field of release agent preparation. Background technique [0002] The release agent is a peeling aid added to the adhesive or pressure-sensitive adhesive of the aluminum foil tape to prevent the aluminum foil tape from sticking to each other seriously and difficult to peel off. It needs to be guaranteed without affecting the adhesive force of the tape itself. Make the tape obtain moderate peeling force. [0003] The existing release agent is to dissolve the active ingredient in an organic solvent such as: toluene, cyclohexanone, etc. and mix evenly. The release agent made by this method is very easy to separate or separate out after being placed for a long time. The use effect will be greatly reduced, which will bring great difficulty and high cost to the storage and transportation of the release agent; at the same time, the organic ...
