Embodiment 1

[0041] The specific process of preparing structural adhesive for sanitary napkin PE film and non-woven fabric is as follows:

[0042] Step 1: Set the temperature of the reactor to 100°C, then add 27 g of naphthenic oil and stir for 10 minutes at a rotation speed of 60 rpm.

[0043] Step 2: The reactor continues to heat up to the first stage temperature of 120°C, add 10.6g SBS792, 2.7g SBS188, 2.7g SIS1105 and 3g paraffin, and continue stirring for 90 minutes at a speed of 60 revolutions / min.

[0044] Step 3: Continue to heat the reactor until the second stage temperature is 140℃, add 43.6g pentaerythritol resin, 10g C5 petroleum resin, 0.15g antioxidant 1010 and 0.15g antioxidant 1076, and stir at 200 rpm for 20 minutes .

[0045] Step 4: The obtained product is discharged after vacuuming for 10 minutes, and is filtered twice through a filter cover with a pore size of 1 cm and a filter cloth bag of 300 meshes, and then placed in a container to cool to room temperature and encapsulate....

Embodiment 2-7

[0048] The process flow in the following embodiments is similar to that of the first embodiment, and the difference lies only in the ratio of the components and the process parameters. The quality of each component in Example 1 and the following examples is shown in Table 2. The process parameters involved in the first embodiment and the following embodiments are shown in Table 3.

Abstract

The invention discloses a structural adhesive used for compositing a sanitary napkin PE membrane and non-woven fabrics. The structural adhesive comprises the following components: 24.3-29.7 parts of naphthenic oil, 48.2-59 parts of synthetic resin, 14.4-17.6 parts of synthetic rubber, 0.27-0.33 parts of an anti-oxidant, 2.7-3.3 parts of paraffin, and 0.09-0.11 parts of an oiliness antifoaming agent. In a traditional structural adhesive, paraffin is added as an auxiliary agent, flowing speed of paraffin due to heat is fast, solidification is fast after cooling, usage temperature is reduced, carbon formation on equipment is reduced, and the production efficiency is increased.

Description

Technical field [0001] The invention relates to a structural composite adhesive of non-woven fabric and cast film in disposable sanitary products, and more specifically, it relates to a structural adhesive for the composite of PE film and non-woven fabric of sanitary napkins and a preparation method thereof. Background technique [0002] In disposable sanitary products, in order to prevent the leakage of disposable sanitary products while ensuring that they have good ventilation function during use, a base film is usually added to the bottom layer of disposable sanitary products. The non-woven fabric and PE film are bonded by structural adhesive. [0003] At present, hot-melt pressure-sensitive adhesives with ethylene thermoplastic elastomers as the main body are mainly used as base film structural adhesives on the market. Usually the base film structure glue is stored as a solid after it is made. During the gluing process, it needs to be melted into a liquid and then glued. In o...
