Problems solved by technology

[0003] At present, pressure-sensitive sealing adhesives are usually used to seal individual packages, but due to the sealing adhesives with better pressure sensitivity, as the storage time prolongs, the wettability of the sealing adhesives to the substrate becomes larger, and the adhesive force is greatly improved. It is easy to tear the packaging film when opening, which is inconvenient to use

Embodiment 1

[0041] The specific process of preparing the sealing line glue for single-piece packaging of sanitary napkins is as follows:

[0042] Step 1: Set the temperature of the reactor to 100° C., then add 20 g of naphthenic oil and stir for 10 min at a speed of 100 rpm.

[0043] Step 2: Continue to heat up the reaction kettle to 120°C, add 25g of SBS1401, 2.7g of SBS791 and 5g of paraffin, and continue to stir for 90min at a speed of 100 rpm.

[0044] Step 3: Continue heating the reactor to 140°C, add 47g of pentaerythritol resin, 0.1g of antioxidant 1010, 0.1g of antioxidant 1076 and 0.1g of oily defoamer, and stir for 20 minutes at a speed of 200 rpm.

[0045] Step 4: The product obtained in step 3 is discharged after being vacuumed for 10 minutes, and filtered twice through a filter cover with a pore size of 1 cm and a filter cloth bag of 300 mesh respectively, and then placed in a container to cool to room temperature before encapsulation.

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

Abstract

A seal line adhesive for a sanitary napkin single-sheet package film is disclosed. The adhesive includes, by weight, 18-22 parts of naphthenic oil, 42.3-51.7 parts of pentaerythritol resin, 25-30.5 parts of synthetic rubber, 0.18-0.22 part of an antioxidant, 4.5-5.5 parts of paraffin and 0.09-0.11 part of an oil-based defoamer. Through adding the paraffin on the basis of traditional seal line adhesives, the production and using temperatures are reduced, and individual packages are protected from being burnt during a production process. Viscosity is reduced after the paraffin is added so that the individual packages cannot be tore during using.

Description

technical field [0001] The invention relates to a plastic film sealing glue for sanitary napkin packaging, more specifically, it relates to a sealing line glue for single-piece packaging film of sanitary napkins and a preparation method thereof. Background technique [0002] In order to ensure the hygiene and safety of disposable sanitary products, it is usually necessary to do independent packaging for disposable sanitary products. PE film is usually used as independent packaging, and the independent packaging of commonly used disposable sanitary products is pasted with label glue. This kind of method just pastes the seal similar to the label on the seal to facilitate the user to open, but the label glue cannot completely seal the seal of the independent package, and it is also inconvenient to carry. There are also seals that are individually packaged for disposable hygiene products with sealing glue. During the production process, the operating temperature should not be to...
