Problems solved by technology

[0003] Adhesives used in diapers on the market are generally polyurethane adhesives, which have the advantages of low cost and are widely used due to their low toxicity. However, it lacks additional functions such as indicating wetness, which can no longer meet the market's requirements for multi-functional diapers; some merchants have added a large number of additional formulas in order to increase its functionality, but the relative cost is relatively high. Unacceptable to ordinary families

Abstract

The invention discloses a hot-melt adhesive for baby diapers. The hot-melt adhesive is prepared from, by weight, 10-20 parts of styrene-containing segmented copolymer, 5-8 parts of tackifying resin, 1-3 parts of softener, 1-3 parts of antioxidant, 0.8-1.0 part of PH color developing agent and 0.1-0.9 part of breathable gum. The styrene-containing segmented copolymer serves as a main formula ingredient, natural rosin resin is added to serve as the tackifying resin, and the natural rosin resin has faint scent, is free of toxins and can replace a traditional baby diaper spice; in addition, the PH color developing agent is added into the formula to serve as the ingredient of the hot-melt adhesive, the PH color developing agent displays colors after making contact with urine, the function of indicating that a baby pisses is achieved, a merchant does not need to add the color developing agent into whole cotton fabric, the production cost is reduced accordingly, and environmental protection safety benefits are increased.

Description

technical field [0001] The invention relates to the field of adhesives, in particular to a hot-melt adhesive for diapers. Background technique [0002] In the sanitary product industry, especially for export sanitary product manufacturers, the application of environmentally friendly products means that the market competitiveness is greatly enhanced. During processing and production, the adhesive is heated and melted and then implanted into sanitary products to be used as an adhesive material. [0003] Adhesives used in diapers on the market are generally polyurethane adhesives, which have the advantages of low cost and are widely used due to their low toxicity. However, it lacks additional functions such as indicating wetness, which can no longer meet the market's requirements for multi-functional diapers; some merchants have added a large number of additional formulas in order to increase its functionality, but the relative cost is relatively high. The average family is u...
