Title:
THERMOCURING CROSSLINKING-TYPE HOT MELT ADHESIVE FILM AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2024/021179
Kind Code:
A1
Abstract:
A thermocuring crosslinking-type hot melt adhesive film, comprising the following components in parts by weight: 50-70 parts of TPU; 40-60 parts of a composite crosslinking agent; 15-25 parts of a phenolic resin; 5-10 parts of a temperature-resistant filler; 5-10 parts of a heat-conducting filler; and 3-8 parts of a light stabilizer. A multi-component crosslinking agent is used, and a main crosslinking agent and an auxiliary crosslinking agent are matched for use, such that the components generate a relatively good synergistic effect, thereby maximally reducing the production cost on the basis of ensuring rapid crosslinking; the systematic combination of a phenolic resin and a temperature-resistant filler greatly enhances the temperature resistance of the adhesive film and improves the corrosion resistance thereof; by adding a heat-conducting filler, a relatively good whisker channel is formed in the adhesive film, such that the heat conduction efficiency of the adhesive film is improved; by adding a light stabilizer, the aging resistance of the adhesive film can be ensured; and compared with a conventional formula, addition proportions and the total amount of various auxiliaries are not changed much, but the reaction speed is high, the curing degree is high, and the thermal conductivity is obviously improved.
