Abstract

The invention discloses a hot melt adhesive. The hot melt adhesive is prepared from, by weight, 30-75 parts of propyl alcohol, 65-85 parts of modified hydrogenated petroleum resin, 35-55 parts of thermoplastic elastomers, 5-15 parts of a viscosity modifier, 4-9 parts of paraffin, 15-35 parts of anion powder and 9-15 parts of polyisobutene. The thermoplastic elastomers are any one of styrene segmented copolymer, polyurethane, diene and polyamide. The anion powder comprises 85% to 95% of tourmaline powder and 5% to 15% of an organic germanium compound. By means of the anion powder, the hot meltadhesive has a sterilizing function, and therefore when the hot melt adhesive is applied to disposable sanitation supplies, the hot melt adhesive is sanitary and clean, and bacterium breeding can be reduced.

Description

technical field [0001] The invention belongs to the field of polymer adhesives, in particular to a hot melt adhesive. Background technique [0002] Hot-melt adhesives are widely used in the disposable hygiene products industry due to their good adhesion and high cost performance, such as women’s hygiene products, diapers and medical supplies, etc.; during the production process of hot-melt adhesives, each raw material is placed directly In the reaction kettle, the reaction kettle is then heated to make the reactants melt; during the heating process, the stirring paddle is continuously stirred to make the reactants uniformly mixed, thereby improving the reaction efficiency of the materials. [0003] Most of the existing hot-melt adhesives on the market can only play the role of bonding. When they are used in disposable sanitary products, they have a single function and cannot achieve the effect of promoting blood circulation and sterilizing bacteria. Contents of the inventi...
