Abstract

The invention discloses an anti-penetration hot melt adhesive for disposable sanitary products and a coating and scraping method. The hot melt adhesive is composed of a main polymer, a tackifying resin, white mineral oil, a processing aid and an antioxidant. The coating and squeegeeing method includes the following steps: melt the anti-seepage hot melt adhesive for disposable sanitary products and add it to the sizing device, the sizing surface on the sizing device matches the surface structure of the substrate, and then apply the glue On the perforated film or non-woven substrate, the substrate is laminated for bonding. The anti-seepage hot-melt adhesive for disposable sanitary products and the coating scraping method of the present invention can significantly reduce the glue seepage in the sizing process, improve the product quality, and will not increase the production cost and process difficulty at the same time, and will not affect the adhesive Junction performance is affected.

Description

technical field [0001] The invention relates to an anti-penetration hot-melt adhesive for disposable sanitary products and a method for coating and squeegeeing the adhesive. Background technique [0002] Hot melt adhesive is a kind of plastic adhesive. Its physical state changes with temperature within a certain temperature range, but its chemical properties remain unchanged. It is non-toxic and tasteless. It is an environmentally friendly chemical product and is widely used in sanitary products, Packaging, bookbinding, clothing, tape, shoemaking, refrigerators, cables, automobiles and other industries. [0003] The top industries in the domestic hot melt adhesive market are hygienic products, clothing, glue sticks, books and packaging, among which the glue used for hygienic products tops the list, and sanitary napkins and baby diapers account for the largest proportion of hygienic products. Disposable hygiene products. The hot melt adhesive market for disposable hygiene p...
