preparation example Construction

[0042] The preparation method of the modified EPDM is as follows: EPDM and acid anhydride are added into a mixer at a weight ratio of 100:8, blended at 185° C. for 3 hours, and then extruded.

[0043] In some preferred embodiments, the filler is selected from zinc oxide.

[0044] In some subdivided applications in the label industry, such as special express delivery sheets, the requirements for hot-melt pressure-sensitive adhesive rolling ball initial adhesion are high, fast labeling, and labels will not drop during use. At present, the hot-melt pressure-sensitive adhesive products on the market can meet the peel strength requirements of customers, but they do not meet the requirements of high rolling ball tack at the same time. This product can meet the high peel strength of customers while greatly improving the rolling ball tack performance of the product. , especially the initial tack properties at low temperatures.

[0045] In some embodiments, the tackifying resin is sel...

Embodiment 1

[0050] Hot melt adhesive, in parts by weight, consists of 80 parts of styrene-butadiene-styrene block copolymer, 20 parts of styrene-ethylene-butylene-styrene block copolymer, 37.5 parts of 4010 naphthenic oil , 7.5 parts of TDAE oil, 18 parts of modified EPDM, 10 parts of C5 petroleum resin, 15 parts of C9 petroleum resin, 8 parts of zinc oxide, 2 parts of 2,6-di-tert-butyl 4-methylphenol.

[0051] The preparation method of the modified EPDM is as follows: adding EPDM and pyridine-3,4-dicarboxylic acid anhydride into a mixer at a weight ratio of 100:8, blending at 185° C. for 3 hours, and extruding to obtain the obtained product.

Abstract

A hot melt adhesive with high rolling ball initial adhesion is at least prepared from, in parts by weight, 100 parts of thermoplastic elastomers, 40-60 parts of rubber oil, 10-20 parts of modified EPDM (ethylene propylene diene monomer), 20-30 parts of tackifying resin, 5-15 parts of filler and 1-5 parts of an antioxidant.

Description

technical field [0001] The invention relates to the field of hot-melt adhesives, in particular to a hot-melt adhesive with high rolling-ball initial tack and a preparation method thereof. Background technique [0002] Express delivery, also known as express delivery or express delivery, means that logistics companies (including freight forwarders) deliver the documents or packages entrusted by users quickly and safely from the sender through their own independent network or in the form of joint venture cooperation (ie networking). The recipient's door-to-door (hand-by-hand) new shipping method. In the express delivery industry, labels are used on all shipments. During the use of labels, customers require that the face sheets can be pasted quickly, and the labels will not be lost during use. Therefore, there is a requirement for the peel strength of the adhesive used for the label. In addition, due to my country's vast territory and large temperature differences, the bondin...
