Description
Technical field
The present invention relates to a kind of disposable sanitary articles to scrape gluing method with impervious hot melt adhesive and coating.
Background technique
Hot melt adhesive is a kind of adhesive of plasticity, its physical state changes with temperature and changed in certain temperature range
Become, and chemical characteristic is constant, it is non-toxic and tasteless, belong to environmental-protecting chemical product, is widely used in hygienic articles, packaging, book
Nationality bookbinding, clothes, adhesive tape, shoemaking, refrigerator, cable, automobile and other industries.
It is hygienic articles, clothes, glue stick, books and packaging respectively that domestic hot melt adhesive market, which accounts for former industries, wherein
Hygienic articles are ranked first with glue, and in hygienic articles accounting it is maximum be sanitary napkin and baby paper diaper both disposably defend
Raw articles.Disposable sanitary articles are the market of a high speed development with hot melt adhesive market, and the past 10 years fitting growth rates are high
Up to 16%.In order to meet the great market demand of disposable sanitary articles, sanitary napkin, diaper production lines linear speed need to improve
Even higher to 800~1000 pieces/minute, the ground that hot melt adhesive is bonded is also more and more thinner, and the use of perforated material is got over
Come more frequent, leads to that it is easy to appear strike-throughs.Strike-through not only will affect the normal operation of production line, reduce production efficiency, and
Can also make a big impact to the quality of product (such as: strike-through will cause adhesion between product, and when use can only tear viscous by force
Product even, it is easy to lead to product breakage).
Currently, solving the problems, such as the method for strike-through mainly include the following types: 1) being adjusted to product core；2) to heat
Melten gel formula is adjusted, and adjusts curing time；3) glue consumption is reduced.Although three of the above method can be to a certain extent
Strike-through is reduced, but also results in the problems such as the production cost increases, technology difficulty increases, cohesive force is inadequate simultaneously.
