Embodiment 1

[0023] The UV-curable pressure-sensitive adhesive of this embodiment is formed by ultraviolet light curing of a composition comprising the following components: 34.4 parts by weight of epoxy soybean oil (ESO)-adipic acid intermediate (30 parts by weight of epoxy soybean oil, 4.4 parts by weight of adipic acid), 60 parts by weight of isooctyl acrylate (2-EHA), 10 parts by weight of acrylic acid (AA), 3 parts by weight of hydroxyethyl acrylate (HEA) and 0.6 parts by weight of 1173 photoinitiator.

[0024] The preparation method of the UV curing pressure-sensitive adhesive of the present embodiment comprises the following steps:

[0025] (1) Preparation of epoxy soybean oil-polyacid intermediate: by epoxy soybean oil (ESO) 30 weight parts, adipic acid 4.4 weight parts, epoxy soybean oil, adipic acid are mixed and stirred and heated, and the temperature is set at 180 ℃, stop heating after reaching the reaction temperature for 6 minutes, and cool to obtain the epoxidized soybean oi...

Embodiment 2

[0030] The UV-curable pressure-sensitive adhesive of this example is formed by UV-curing a composition similar to that of Example 1, except that the amount of hydroxyethyl acrylate used in the composition of this example is 6 parts by weight.

[0031] The preparation method of the UV-curable pressure-sensitive adhesive of this embodiment is the same as that of Embodiment 1 except for the amount of hydroxyethyl acrylate added.

[0032] For the preservation of the UV-cured pressure-sensitive adhesive strips in this embodiment, the 180° peel strength of the adhesive strips was tested on an electronic tensile machine according to the GB / T 2792-2014 standard. The test results are shown in Table 1.

Embodiment 3

[0034] The UV-curable pressure-sensitive adhesive of this example is formed by curing a composition similar to that of Example 1 through ultraviolet light, except that the amount of acrylic acid used in the composition of this example is 15 parts by weight.

[0035] The preparation method of the UV-curable pressure-sensitive adhesive of this embodiment is the same as that of Embodiment 1 except for the amount of acrylic acid added.

[0036] For the preservation of the UV-cured pressure-sensitive adhesive strips in this embodiment, the 180° peel strength of the adhesive strips was tested on an electronic tensile machine according to the GB / T 2792-2014 standard. The test results are shown in Table 1.

Abstract

The invention discloses a UV-cured pressure-sensitive adhesive and a preparation method thereof. The pressure-sensitive adhesive is formed by ultraviolet curing of a composition comprising the following components: 60 parts by mass of 2-ethylhexyl acrylate, 34.4-36 parts by mass of an epoxidized soybean oil-polybasic acid intermediate, 10-25 parts by mass of acrylic acid, 3-6 parts by mass of hydroxyethyl acrylate and 0.6-1 part by mass of a photoinitiator, the epoxidized soybean oil-polyatomic acid intermediate is prepared by mixing and heating epoxidized soybean oil and polyatomic acid. The preparation method comprises the following steps: preparing an epoxidized soybean oil-polyatomic acid intermediate, preparing a pressure-sensitive adhesive solution, and coating and curing. According to the UV-cured pressure-sensitive adhesive disclosed by the invention, the epoxidized soybean oil is adopted to replace part of fossil raw materials to react with polybasic acid, so that the peel strength is remarkably improved, the mechanical property is controllable, volatile components are close to zero, the environmental pollution is small, the adhesive surface is flat, and the adhesion performance distribution is uniform; the preparation method is simple to operate, low in energy consumption, low in production cost and suitable for large-scale industrial production.

Description

technical field [0001] The invention relates to the technical field of pressure-sensitive adhesives, in particular to a UV-cured pressure-sensitive adhesive and a preparation method thereof. Background technique [0002] Acrylic pressure-sensitive adhesives are widely used in the current market due to their excellent performance. Compared with other pressure-sensitive adhesives, acrylic pressure-sensitive adhesives have the following advantages. First of all, the formula is simple, the product has high transparency, no tackifying resin is generally added during the synthesis process, and acrylate pressure-sensitive adhesive products are generally colorless. Secondly, it has good weather resistance and low toxicity. Most acrylic pressure-sensitive adhesives are non-toxic or low-toxic and can be used in medicine and various packaging. Finally, the bonding range is relatively wide, and acrylate pressure-sensitive adhesives have very good bonding properties to ceramics, glass, ...
