Abstract

The invention provides a special mosquito-repellent end sealing adhesive for paper diapers and a preparation process thereof. The mosquito-repellent end sealing adhesive special for the paper diaper is prepared from 65 to 77 parts of ethylene-vinyl acetate copolymer, 10 to 20 parts of modified poly alpha-olefin, 20 to 30 parts of tackifying resin, 0.01 to 0.1 part of mosquito repellent, 0.2 to 0.8 part of antioxidant, 0.1 to 0.25 part of filler, 1 to 4 parts of microcrystalline wax, 0.2 to 0.6 part of polyethylene glycol and 0.4 to 1 part of dioctyl phthalate. The preparation process comprises the following steps: adding the raw materials into a mixing mill, heating to 45-60 DEG C while stirring, keeping the temperature at 45-60 DEG C for 2-5 hours, continuously heating to 145-165 DEG C, keeping the temperature at 145-165 DEG C for 1-5 hours, and cooling to 25-45 DEG C, thereby obtaining the product. The special mosquito-repellent end sealing adhesive for the paper diaper, provided by the invention, has a mosquito-repellent effect due to the addition of the mosquito repellent, also has good high and low temperature resistance, can keep good binding power at a high temperature, has good opening time at a low temperature, and meets different application scenes and use requirements. The paper diaper can be widely applied to disposable hygienic products such as paper diapers.

Description

technical field [0001] The invention relates to an end sealant, in particular to a special mosquito repellent end sealer for paper diapers and a preparation process thereof. Background technique [0002] Diapers are items for people who cannot take care of themselves such as babies or the elderly. They are made of materials such as non-woven fabrics, toilet paper, fluff pulp, polymer water-absorbent resin, PE film, rubber bands, structural adhesives, back adhesives, and end seals. , to bring convenience to daily life. As people pursue the improvement of the quality of life, new requirements are put forward for the functions of diapers, such as diapers with antibacterial, deodorizing, and physical therapy functions. Most of the current end-seals for diapers do not have the function of repelling mosquitoes, and there is a lack of such functional end-seals on the market. Contents of the invention [0003] In order to solve the above problems, one of the objectives of the pr...
