Example Embodiment

[0046] Example 1-7: A hot melt pressure-sensitive adhesive for diapers, including components and corresponding contents as shown in Table 1. Among them, the softening agent is rubber oil, the tackifying resin is C5 / C9 copolymerized petroleum resin, the polymer elastomer is a compound of SBS and SIS, and the weight ratio of the two is 1.8:2.

Example Embodiment

[0047] Example 8: Hot melt pressure-sensitive adhesive for diapers. The difference from Example 1 is that the tackifying resin is a terpene resin.

Example Embodiment

[0048] Example 9: Hot melt pressure sensitive adhesive for diapers. The difference from Example 1 is that the tackifying resin is a mixture of terpene resin and C5 / C9 copolymerized petroleum resin, and the weight ratio of the two is 1:1.

Abstract

The invention discloses a hot-melt pressure-sensitive adhesive for a paper diaper. The hot-melt pressure-sensitive adhesive for the paper diaper comprises components of a polyolefin copolymer, an antioxidant, a softener, a tackifying resin and a polymeric elastomer, wherein the softener is rubber oil, the tackifying resin is hydrogenated resin, and the polymeric elastomer is a compound of SBS andSIS; the invention further discloses a production method of the hot-melt pressure-sensitive adhesive for the paper diaper, comprising the following steps: heating a reaction vessel and putting into the softener, adding a part of the tackifying resin and heating to be molten, putting into the polymeric elastomer and the antioxidant to be reacted, adding the polyolefin copolymer and the balance of the tackifying resin and melting, heating and stirring until the reaction is finished. The hot-melt pressure-sensitive adhesive for the paper diaper has the effects of strong viscosity, high fastness and difficult aging and falling-off.

Description

technical field [0001] The invention relates to the technical field of hot-melt adhesives and production, more specifically, it relates to hot-melt pressure-sensitive adhesives for paper diapers and a production method thereof. Background technique [0002] Hot melt adhesive is a kind of plastic adhesive. Its physical state is different under heating and normal temperature, but its chemical properties remain unchanged. It is non-toxic and tasteless, and it is an environmentally friendly chemical product. Because it is solid at room temperature, it is easy to pack, transport, store, has no flux, no pollution, and is non-toxic; and it has the advantages of simple production process, high added value, high bonding strength, fast speed, and easy construction. . [0003] Hot-melt pressure-sensitive adhesive is mainly made of synthetic rubber mixed with resin and rubber oil, and has a wide range of applications, such as diapers, sanitary pads and other products. However, in the ...
