Description
Technical field
The present invention relates to hot melt adhesive technical field, especially a kind of TPU glue film and preparation method thereof that low temperature easily bonds.
Background technique
Thermoplastic polyurethane (TPU) is line style or the polymer with a small amount of branch, it has excellent mechanical performance, wear-resisting
Property and resilience.TPU glue film has relaxing for good soft bendability, waterproofness, hydrolytic resistance, the transparency and human contact
The performances such as adaptive and easy processing, adhesion strength is high, can be bonded well with multiple material.
TPU hot melt adhesive is applied relatively broad at present, and TPU hot melt adhesive has many advantages, such as that positioning is convenient, and peel strength is high, is one
Kind bonding and the excellent hot melt adhesive of sealing performance, but TPU hot melt adhesive film processing temperature is higher, and hot or oxidative degradation easily occurs, it is low
The lower tack of temperature is poor, it is more difficult to carry out processing with material and be bonded.If gluing is bonded with laminated material on TPU glue film,
Degumming easily occurs, bonds the problems such as insecure.
Currently, TPU hot melt adhesive film processing, in terms of there are some disadvantages, especially:
1, processing binding temperature is higher, and generally at 80-160 DEG C, heat or oxidative degradation easily occur for laminated material.
2, tack is poor under low temperature, and fitting winding is more difficult.
3, more difficult after being bonded to do over again, easily cause material loss.
Summary of the invention
The technical problem to be solved by the present invention is overcoming deficiency in the prior art, a kind of TPU glue that low temperature easily bonds is provided
Film and preparation method thereof.
To achieve the above object, The technical solution adopted by the invention is as follows:
