Problems solved by technology

From the process point of view, it takes more than 24 hours for the mixed glue to really work, and the efficiency is low.
Moreover, there is a limit on the use time of the mixed glue. In addition, the solvent-free two-component glue needs more than 2 days to cure and then confirm whether the adhesive strength is qualified, so the waiting time for testing in production is very long. If there is a problem, it is basically A batch of problematic products has been made

Embodiment 1

[0057] The electron beam curing composite adhesive provided in this embodiment is made of raw materials with the following mass parts:

[0058]

[0059] among them:

[0060] The 2-functional aliphatic urethane acrylate was purchased from Taiwan Changxing Chemical Eternal, the model is DR-U301, and the weight average molecular weight is 15,000-20,000.

[0061] The 2-functional polyester acrylate is a modified 2-functional polyester acrylate resin, which is purchased from Foshan Dechuang United Polymer Materials Co., Ltd., and the model is UV938A.

[0062] Organic-inorganic hybrid material 604X35 was purchased from Taiwan Changxing Chemical.

[0063] Silane coupling agent SN-7535 was purchased from Shanghai Shenzhu Chemical.

[0064] The flexible packaging composite film prepared by the above-mentioned electron beam curing composite adhesive can be used.

[0065] The preparation method of the flexible packaging composite film includes the following steps:

[0066] (1) Select the raw material...

Embodiment 2

[0073] The difference from Example 1 is that in step (2), the first flexible packaging film is polyethylene terephthalate film (PET), and the second flexible packaging film is polyethylene film (PE). PE.

Embodiment 3

[0075] The difference from Example 1 is that in step (2), the first flexible packaging film is a biaxially oriented polyamide film (NY), and the second flexible packaging film is a polyethylene film (PE), which is made of NY / PE.

Abstract

The invention discloses an electron beam curing compound adhesive. The electron beam curing compound adhesive is prepared from the raw materials in parts by mass: 30-50 parts of two-degree-of-functionality aliphatic polyurethane acrylate, 10-30 parts of two-degree-of-functionality polyester acrylate, 10-15 parts of acryloylmorpholine, 10-20 parts of N,N-dimethylacrylamide, 10-15 parts of an organic and inorganic hybrid material and 0.5-2 parts of a silane coupling agent. According to the electron beam curing compound adhesive, an electron beam is adopted for curing, curing is fast, curing canbe achieved instantaneously (curing can be achieved for 0.01 second or even 0.005 second), and before the electron beam is not adopted for curing, the compound adhesive can be used repeatedly. The invention further discloses a flexible package compound film prepared from the electron beam curing compound adhesive and a preparation method of the flexible package compound film.

Description

Technical field [0001] The invention belongs to the technical field of curing adhesives, and specifically relates to an electron beam curing composite adhesive, a flexible packaging composite film and a preparation method thereof. Background technique [0002] At present, the social flexible packaging film composite uses environmentally friendly solvent-free composite glue, the main components are: NCO component and OH component, the method of use is, the first step is to mix the NCO component and the OH component in proportion (usually 100 :85), the gluing compound roller system is heated by 40-50℃, and the roller is glued and glued. Step 2 The composite product can be processed by slitting when it is naturally cured for 48 hours at room temperature ≥30℃; if bag making or packaging processing is required, it should be cured at 35-45℃ and relative humidity 60%-70% for 24-hours. 48 hours. [0003] It can be seen that the ordinary solvent-free two-component glue is mixed at a tempe...
