Abstract

The invention provides a mosquito-repellent structural adhesive special for paper diapers and a preparation method thereof. The structural adhesive is prepared from the following components in parts by weight: 150 to 200 parts of thermoplastic elastomer, 25 to 40 parts of paraffin, 280 to 400 parts of naphthenic oil, 450 to 520 parts of rosin pentaerythritol ester, 100 to 160 parts of modified petroleum resin, 0.06 to 0.15 part of plant mosquito repellent, 0.03 to 0.08 part of tri (2, 4-di-tert-butylphenyl) phosphite ester, 1 to 5 parts of antioxidant and 0.05 to 0.15 part of defoaming agent. The structural adhesive for the paper diaper is added with plant mosquito-repelling components, emits fresh fragrance, is safe and harmless to human bodies, can repel mosquitoes and insects, and can reduce mosquito bites of wearers and improve comfort when being used in the paper diaper. The structural adhesive has the advantages of being high in bonding strength, lasting in bonding force, high in infiltration speed, free of reverse osmosis, smooth in appearance of a glued product and the like, is not prone to carbonization in the using process, and can be widely applied to disposable hygienic products such as paper diapers.

Description

technical field [0001] The invention relates to a structural adhesive, in particular to a special mosquito repelling structural adhesive for paper diapers and a preparation method thereof. Background technique [0002] In the production of disposable hygienic products such as diapers, in order to ensure the leakage absorption effect and better air permeability during use, a bottom film is usually added to the bottom layer. The bottom film is generally made of non-woven fabric It is bonded with PE film by structural adhesive. Hot melt pressure sensitive adhesives are divided into structural adhesives and back adhesives. Structural glue is to stick the surface layer, bottom layer material and internal structural materials of diapers together so that they will not move or break. At present, the sizing methods of structural adhesives include spiral spray glue, fiber spray glue, coating scraping glue, etc., and spiral spray glue is commonly used. [0003] Hot-melt pressure-sen...
