Problems solved by technology

In the production process of electrical appliances, a large number of people are required to carry out the tape bonding process, and when consumers remove the tape in the later stage, there will often be more tape residues on the partitions that need to be cleaned, which is time-consuming and labor-intensive, and may damage The surface of the partition will cause problems such as unsightly, and the removed tape will also stick to hands, floors, etc., making it difficult to clean

preparation example Construction

[0055] The present invention also provides a method for preparing a peelable hot-melt adhesive for electrical packaging, comprising the steps of:

[0056] S1: Confirm that the bottom valve of the reaction kettle is closed, turn on the steam heating, turn on the stirring paddle, and slowly add rubber oil and antioxidant;

[0057] S2: Raise the temperature of the reactor in S1 to 160-170°C, add the formulated amount of rubber polymer, and after the rubber polymer is completely added, scrape off the tank wall of the reactor and the rubber polymer on the stirring paddle with a scraper, After stirring for about 40 minutes, take a sample to see if the sample is completely melted. If the rubber polymer is not completely melted and there are still particles, then continue to stir, record and extend the stirring time until the rubber polymer particles are completely melted;

[0058] S3: After the polymer in S2 is completely melted, add the tackifying resin evenly and stir. After all th...

Abstract

The invention discloses a peelable hot melt adhesive for packaging electric appliances and a preparation method thereof. The peelable hot melt adhesive comprises the following components in percentage by mass: 2-10% of synthetic wax, 30-50% of rubber oil, 25-40% of a rubber polymer, 3.5-11% of an acrylic polymer, 10-20% of tackifying resin and 0.1-1% of an antioxidant. The sum of the mass percentages of the components is 100%. The hot melt adhesive prepared by the invention replaces an adhesive tape for fixing a partition plate in an electric appliance through the design of a formula, so that a better appearance feeling is brought to consumers; and meanwhile, the peelable hot melt adhesive disclosed by the invention is moderate in bonding strength, high in softness, high in strength and non-sticky in surface after being solidified, so that a consumer can remove the peelable hot melt adhesive more simply, and the peelable hot melt adhesive has the advantages that no residue is left on a partition plate in the adhesive stripping process, an adhesive tape is not sticky to hands and the like, the safety in the transportation and storage processes of electrical products is ensured, and meanwhile, the hot melt adhesive is easy to peel off, free of residues, free of sticking to skin, environment-friendly and harmless when an electric appliance is disassembled and assembled.

Description

technical field [0001] The invention relates to the application field of hot-melt adhesives, in particular to a peelable hot-melt adhesive for electrical appliance packaging and a preparation method thereof. Background technique [0002] Hot melt adhesive is a kind of plastic adhesive, which is an environmentally friendly chemical product. In refrigerators, disinfection cabinets, ovens and other electrical appliances with compartments, in order to ensure that stainless steel grids, glass and other partitions will not be deformed or broken due to collisions, drops, etc. during storage and transportation, during the production of electrical appliances , will use adhesive tape to fix the partitions, and consumers will remove the adhesive tape after purchasing electrical appliances for later disassembly and cleaning. In the production process of electrical appliances, a large number of people are required to carry out the tape bonding process, and when consumers remove the tape...
