preparation example Construction

[0047] The preparation method of the above-mentioned high-temperature removable label hot-melt adhesive comprises the following steps:

[0048] (1) Add paraffin oil, naphthenic oil, antioxidant in stainless steel reactor, heat up to 140 ℃;

[0049] (2) Then add modified EPDM and SEBS, add SIS after 30 minutes, and keep stirring until the whole system is completely melted;

[0050] (3) After the whole system is completely melted, add C5 hydrogenated petroleum resin and C9 hydrogenated petroleum resin, stir evenly, vacuumize for 20 minutes, and discharge the material. After cooling, you can get a high-temperature removable label hot melt adhesive.

Embodiment 1-3 and comparative example 1-5

[0053] Weigh the raw materials according to the proportions in Table 1, respectively, and make hot melt adhesives according to the preparation methods after Table 1, correspondingly to obtain hot melt adhesives in different embodiments, see Table 1 for details:

[0055]

[0056]

[0057] Wherein, if there is no special instruction in Table 1, in order to reflect the comparability of test effect, the raw material that adopts is consistent, as paraffin oil is 100# paraffin base oil; SIS was purchased from Shandong Jusheng Technology Co., Ltd. SIS with brand number 1220; SEBS was purchased from SEBS rubber with brand number 1652 from Kraton Company of the United States; C5 hydrogenated petroleum resin was purchased from C5 hydrogenated petroleum resin produced by Eastman Company of the United States; C9 hydrogenated petroleum The resin was purchased from C9 hydrogenated petroleum resin prod...

Abstract

The invention discloses a high-temperature movable label hot melt adhesive and a preparation method thereof. The high-temperature movable label hot melt adhesive is prepared from the following components in parts by weight: 5-30 parts of paraffin oil, 5-30 parts of naphthenic oil, 1-5 parts of an antioxidant, 10-30 parts of modified EPDM, 10-30 parts of SIS, 5-30 parts of SEBS, 15-50 parts of C5 hydrogenated petroleum resin and 15-50 parts of C9 hydrogenated petroleum resin, wherein the modified EPDM is acid anhydride modified EPDM, and the acid anhydride is phthalic anhydride. Through the design of the formula, the thermoplastic elastomers SIS and SEBS and the high-temperature-resistant chemical modified EPDM are blended, and then the naphthenic oil and the paraffin oil are added to act together, so that the problems of mark warping and adhesive residue in a high-temperature environment are solved.

Description

technical field [0001] The invention relates to a hot-melt adhesive technology, in particular to a high-temperature removable label hot-melt adhesive and a preparation method thereof. Background technique [0002] Removable labels are also known as environmentally friendly labels and N-time labels. They will not produce traces when they are torn off. The labels are intact and can be reused many times. Removable labels use removable glue as an adhesive. At present, the removable adhesives used in the removable label market are mainly water-based adhesives and oil-based adhesives, and both water-based adhesives and oil-based adhesives have certain pollution to the environment. In the prior art, more environmentally friendly hot-melt adhesives are used instead of water-based adhesives and Oil-based glue, as an adhesive for removable labels, occupies a certain share in the market and is also the future development trend. [0003] The existing removable labels mainly include sev...
