Problems solved by technology

In order to speed up the melting, it is usually necessary to increase the temperature of the equipment to above the melting point of the structural adhesive. However, after some components in the structural adhesive are raised to a higher temperature, the heating time is too long and it is easy to carbonize, and impuri

Abstract

The invention discloses a hot melt adhesive for a sanitary product. The hot melt adhesive is prepared from the following components in parts by weight: 30-35 parts of naphthenic oil, 55-65 parts of modified hydrogenated petroleum resin, 15-20 parts of synthetic rubber, 0.3-0.6 part of an antioxidant, 5-8 parts of paraffin, 12-22 parts of negative ion powder and 0.02-0.3 part of an oily defoamer. The modified hydrogenated petroleum resin is modified C5 modified hydrogenated petroleum resin which is synthesized by carrying out a reaction of maleic anhydride and C5 hydrogenated petroleum resin under the action of a catalyst. By adding paraffin into the conventional structural adhesive, the structural adhesive has very a good flowing property when being lower than the temperature of the conventional structural adhesive and promotes mutual mixing of the components. Due to the adoption of the negative ion powder which has a sterilizing function, the hot melt adhesive applied to the disposalsanitary product is not only sanitary and clean, but also can reduce bacteria breeding.

Description

technical field [0001] The invention belongs to the field of polymer adhesives, and in particular relates to a hot-melt adhesive used for sanitary products and a production process thereof. 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] In disposable sanitary products, in order to prevent the leakage of disposable sanitary products and at the same time ensure that they have good air permeability during use, a bottom film is usually added to t...
