Embodiment 1

[0103] According to the present invention, the following binder mixture is prepared. When tested, the adhesive provided sufficient peeling and shear bonding strength at higher temperatures, and the performance was very excellent. Due to the use of polybutene homopolymer, amorphous poly-α-olefin with high softening point and tackifier with high softening point, the sample of this example has good high temperature strength.

Embodiment 2

[0104] The formulation of this example of the invention does not contain wax. This embodiment uses a high softening point tackifier and amorphous poly-α-olefin, and a mixture of polybutene homopolymer and polybutene-ethylene copolymer. No wax is used in this formula, so the viscosity is increased, but the compound has greater toughness and has a longer mold opening time than in Example 1.

Abstract

The present invention discloses a polybutylene-based hot melt adhesive composition which has a variety of end uses, particularly in the construction and elastic bonding of nonwoven articles such as disposable diapers. Unlike typical hot melt adhesives, the compositions of the present invention can withstand high peel and shear at elevated temperatures for extended periods of time without severe bond failure. The composition comprises a polybutene polymer or a mixture of polybutene and polyolefin polymers, and a stabilizer, and one or more remaining groups selected from polyolefin polymers, tackifying resins, plasticizers or waxes point. The hot melt adhesive composition can be applied by conventional application techniques, such as extrusion or spraying.

Description

Background of the invention [0001] The present invention relates to a hot-melt adhesive composition. More specifically, the present invention relates to a polybutene-based hot-melt adhesive for non-woven disposable absorbent articles such as diapers. [0002] Many types of disposable absorbent articles are commercially available, and they are used to absorb and retain body exudates, such as urine and excrement. Typical examples of such products are disposable diapers for babies and underwear for adults that cannot be self-made. Typically, hot melt adhesives are used in the construction of such disposable products. [0003] Although many hot-melt adhesive compositions are known and used in the construction of disposable products, the hot-melt adhesive used for bonding in a specific application may be completely unsuitable for other applications. , This is also well known. Therefore, various hot melt adhesive compositions are used in the construction of disposable articles. For exam...
