Aramid fiber length is 2-2.5mm, filament diameter 8-10 μm, carries out modification in accordance with the following methods: aramid fiber is soaked 8-10 hour in acetone, then in water and ethanol, boils 2-3 hour respectively, dry for standby.
The modified tackiness agent prepared through aforesaid method, according to same testing method, its average tensile strength reaches 56MPa, elongation rate of tensile failure 462%, and extract power 723N out, softening temperature 110 DEG C, overall performance has had more again certain raising.
In addition Chinese patent 200610044558.5 discloses a kind of steel cord compound adhensive for radial ply type and its Preparation Method, record according to it, its tackiness agent prepared is that steel wire extracts power 489N out, softening temperature 106 DEG C according to the average data that above-mentioned performance test methods draws; And through above-mentioned performance test methods, conventional tackifier PN759 show that draw data are extraction power 526N, softening temperature 102 DEG C, technical indicator is also not as the present invention, therefore the tackiness agent that prepared by the present invention can either improve the intensity of sizing material self, the bond strength of rubber and steel wire cord can also be improve, the technical requirements of radial can be met completely.
