Problems solved by technology

Generally, when the diaper is wet, it needs to be replaced immediately and cannot be used repeatedly
The glue between the layers of the urine-proof pad is realized by hot-melt adhesive, but the hot-melt adhesive used in the existing urine-proof pad has poor waterproof performance, and the urine-proof pad will be wet after the urine leaks. The hot melt adhesive is not good in adhesion, which makes the layers separate from each other, and the urine pad is not easy to use after people turn over or move on the bed

Abstract

The invention discloses a waterproof underpad hot melt adhesive excellent in waterproof effect. The waterproof underpad hot melt adhesive excellent in waterproof effect comprises an ethylene-vinyl acetate copolymer, a styrene-butadiene-styrene block copolymer, talcum powder, a tackifier, an anti-oxidant, naphthenic oil, paraffin oil, microcrystalline wax, liquid paraffin, and dicyclohexyl phthalate. The viscosity of the waterproof underpad hot melt adhesive is not influenced even the surface of the waterproof underpad is wetted by penetrated urine, the bonding effect among layers of the waterproof underpad is maintained, the raw materials are widely and easily available, and are cheap, and the safety is high.

Description

technical field [0001] The invention relates to the technical field of urine-separating pads, in particular to a hot-melt adhesive for urine-separating pads with good waterproof effect. Background technique [0002] In modern life, comfort has become one of the indicators of people's happiness. As the elderly, children and patients who need to be cared for, they need to pay more attention to comfort. Especially babies and the elderly with limited mobility cannot take care of themselves. Now products such as urine pads and diapers have been developed to solve these problems. Urinary pads, also known as waterproof sheets, are mainly used to isolate urine to ensure that the mattress or mattress below is not soaked by urine. Generally, when the diaper is wet, it needs to be replaced immediately and cannot be used repeatedly. The glue between the layers of the urinal pad is realized by hot melt adhesive, but the hot melt adhesive used in the existing diaper pad has poor waterp...
