[0002] All kinds of paper towels used in daily production, such as toilet paper, kitchen paper, etc., are made of more than two layers of paper, and the layers are bonded with adhesives, but this bonding strength It cannot be too high, because this kind of composite paper is required to be peelable, that is, after the two layers of paper are combined with an adhesive, when the two layers of paper are separated, the two layers are required to be intact. Therefore, if the bonding strength is too high , when the paper is separated, it will inevitably lead to the destruction of the paper
[0003] At present, water-based adhesives are widely used as adhesives for paper towels, but there are many disadvantages in the application of water-based adhesives in paper towels, as follows: (1) Due to the large amount of w

Abstract

The invention relates to a tissue paper compounding hot melt adhesive which is composed of, by mass, 20-45% of APAO resin, 30-60% of tackifying resin, 2-15% of a plasticizer, 1-15% of montan wax and 0.2-0.8% of an antioxidant. The APAO resin has a propylene content of 60-75%, a glass transition temperature of -40 DEG C to -20 DEG C, and a viscosity of 3000-10000cps under a temperature of 190 DEG C. The tackifying resin is hydrogenated petroleum resin with a softening point of 60-90 DEG C. the tissue paper compounding hot melt adhesive provided by the invention does not contain water, such that no water penetrates into the tissue paper during a tissue paper production process. Therefore, tissue paper performances such as hand feeling, strength and comfortableness can be ensured, and paper quality decrease caused by water penetration can be avoided. The adhesive also has the advantages of high curing speed, excellent strippability, long exposure time, good fluidity, good safety, good environment friendliness, no toxicity, and no odor. The adhesive has a good application prospect.

Description

technical field [0001] The invention belongs to the technical field of hot-melt adhesives, and in particular relates to a hot-melt adhesive for compounding paper towels and a preparation method thereof. Background technique [0002] All kinds of paper towels used in daily production, such as toilet paper, kitchen paper, etc., are made of more than two layers of paper, and the layers are bonded with adhesives, but this bonding strength It cannot be too high, because this kind of composite paper is required to be peelable, that is, after the two layers of paper are combined with an adhesive, when the two layers of paper are separated, the two layers are required to be intact. Therefore, if the bonding strength is too high , when the paper is separated, it will inevitably lead to the destruction of the paper.
