Hot melt adhesive layer is the main component for making hot melt adhesive, and according to required proportion when preparation, the ratio of hot melt adhesive layer is determined
The basic performance of hot melt adhesive, such as glue the selection of cohering ability, melting temperature and auxiliary agent and prepare, all with basic resin
Depending on ratio is different, therefore binds EVA hot-melt adhesive used and should need properly to select ethylene and acetic acid second according to object is sticked
The ratio of alkene selects to have certain flexibility, elasticity, adhesion, deforms small etc. kind to be deployed.
(some substances for capableing of congruent melting with basic resin are added, it is therefore intended that increase its bond performance, this is just needed in tackifier
Mix tackifier.Suitable tackifier is added in EVA hot-melt adhesive can also improve the mobility of colloid, to enhance colloid pair
It is sticked the wetting and penetrating power of object, improves bond strength, meet this needs to bond strength of books.
(tackifier are also one of main auxiliary agent of hot melt adhesive to tackifier, and effect is to reduce melting viscosity, increase flowing
Property, wetability, adjust setting rate, quickly cohere firm purpose to reach.There is no the addition of tackifier, colloid will viscosity
Too small, application difficulties are not easy to cohere securely.
(because of temperature drift oxygenolysis can occur antioxidant for colloid in melting, and suitable antioxidant, which is added, to be prevented
The premature aging of hot melt adhesive.And under the high temperature conditions, suitable antioxidant is added, the stickiness of adhesive will not become
Change, it is sufficient to which effect is cohered in guarantee.It is BHT (di-tert-butyl methyl phenol class) that antioxidant is also available, and effect is relatively good,
Dosage general control is advisable 0.5% or so.) antioxidant is also selected from phosphite ester antioxidant, containing sulphur ester antioxidant
At least one of.
It is listed following for above embodiments and Hot melt adhesive tape performance in the prior art by its performance of verification experimental verification
Table:
Contrast on effect through the foregoing embodiment, it is known that, the present invention by hot melt adhesive layer formula and processing step into
Row improves, and compares common Hot melt adhesive tape performance in the prior art, hence it is evident that it can be seen that Hot melt adhesive tape performance of the invention is more
Superior, performance is further improved, and is suitble to promote the use of.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
