Description

Tire bead steel wire adhesive

Technical field

The present invention relates to tire bead steel wire adhesive, belong to tire and make the field.

Background technology

The tire bead steel wire adhesive is to stick on the steel wire by extruding, and the steel wire set in the Steel Traveler is as a whole, after sulfuration Steel Traveler is combined firmly with tire.Existing tire bead steel wire adhesive prescription generally is made up of 1～3# smoke sheet rubber, styrene-butadiene rubber(SBR), general carbon black, lime carbonate, potter's clay, aromatic hydrocarbon oil, zinc oxide, stearic acid, amines antioxidants, colcother, ancient marlon resin, pitch, sulfenamide type accelerators and common sulphur.Traditional steel wire adhesive adopts the sulphur content of high mixture ratio, though the sizing material cost is lower, and the easy bloom of gained sizing material, processing performance is relatively poor, and prescription starting material composition is complicated, and rubber mixing technique operation and raw materials inventory management are difficult for.The prescription of existing steel wire adhesive adopts "-first-Bai " or "-first-Bai-cobalt " binding system more, as publication number is the Chinese invention patent of CN1351103, a kind of adhesive for steel wires of tyre is disclosed, consisting of of it: 1500 butadiene-styrene rubbers 12.92%～14.28%, zinc oxide 3.43%～3.79%, stearic acid 0.86%～0.95%, 4020 anti-aging agent 0.34%～0.38%, RD anti-aging agent 0.43%～0.48%, ancient Malong 2.15%～2.37%, Resorcinol 0.43%～0.48%, white carbon black 4.29%～4.75%, ultra-fine potter's clay 4.29%～4.75%, colcother 0.86%～0.95%, NOBS promotor 0.34%～0.38%, H promotor 0.43%～0.48%, NMP-ZD coupling agent 0.34%～0.38%, sulphur 2.48%～2.57%, N330 high wear-resistant carbon black 30.02%～33.18%, aromatic hydrocarbon oil 1.29%～1.43%, all the other are 1～No. 3 smoke sheet rubbers, and said per-cent is weight percentage.The steel wire of this patent formulation gained sizing material is extracted out better, but its formulation cost is higher, and prescription is complicated, the carbon black of high structure and white carbon black content height cause the rubber mixing technique operation also very difficult, the its surface compressed of sizing material is big, peels off glue when Steel Traveler is rolled into moulding easily, the steel ring quality instability of moulding.

Summary of the invention

The technical problem to be solved in the present invention provides that a kind of bounding force height, cost are low, good manufacturability, composition are simple, give birth to the low tire bead steel wire adhesive of heat.

Tire bead steel wire adhesive is made of following component by weight:

Rubber components, is made up of the styrene-butadiene rubber(SBR) of 1～3# smoke sheet rubbers of 50～70 parts and 30～50 parts by 100 parts;

The N660 carbon black, 40～60 parts;

Lime carbonate, 30～50 parts;

Potter's clay, 80～110 parts;

Stockholm tar, 8～15 parts;

Hard ester acid, 1～3 part;

Zinc oxide, 5～10 parts;

Common sulphur, 5～10 parts;

2,2,4-trimethylammonium-1,2-dihyaroquinoline polymer (anti-aging agent RD), 1～3 part;

N-(1, the 3-dimethylbutyl) N-diphenyl-para-phenylene diamine (anti-aging agent 4020), 1～3 part;

N-oxy-diethlene-2-henzothiazole-sulfenamide (accelerant N OBS), 0.5～2 part;

With the tall oil modified phenolic aldehyde reinforced resin of compound vulkacit H be main component toughener, 1.5～3.5 parts.

Wherein, described styrene-butadiene rubber(SBR) is styrene-butadiene rubber(SBR) 1500, styrene-butadiene rubber(SBR) 1502 or styrene-butadiene rubber(SBR) 1500E.

The described toughener that is main component with the tall oil modified phenolic aldehyde reinforced resin of compound vulkacit H is toughener HMZ.

In the present invention's prescription, 1～3# smoke sheet rubber is a main raw, cross-linked rubber tensile strength height, and good springiness, it is good to cover glue in Steel Wire Surface, and the steel wire adhesive tape smooth surface of extruding has good autohension when Steel Traveler is rolled into; The N660 carbon black that reinforcement system uses belongs to soft furnace black, add be easy to man-hour mixing, smooth surface and the reducing cost when lime carbonate of use and potter's clay are extruded sizing material; Zinc oxide and stearic acid have been formed activation system in the vulcanization system in the sulfur cross-linking system, activated whole vulcanization system, improve the cross-linking density of cross-linked rubber, improved the heat aging property of cross-linked rubber, sulphur-the accelerator level of high mixture ratio has improved the bonding of sizing material and steel wire, use sulfenamide type accelerators NOBS can make sizing material have long glue and burn the time, vulcanization rate has improved the bonding of cross-linking density and sizing material and steel wire faster; Protection system adopts anti-aging agent RD+4020, anti-aging agent 4020 good antioxygen, anti-ozone to be arranged, anti-ly deflect effect, Weather is also had protective effect preferably, and variable valency metal is had passivation, and anti-aging agent RD is splendid to the thermo-oxidative ageing effect; Toughener HMZ makes the sizing material extrusion performance good, and the work in-process property endured is suitable, and hardness height, modulus height, tenderizer Stockholm tar can make sizing material be uniformly dispersed, and reduces the sizing material mooney viscosity, reduces mixing time, regulates sizing material hardness and time of scorch.

Tire bead steel wire adhesive of the present invention adopts the ordinary method preparation.The performance of gained sizing material is as shown in table 1:

Table 1: properties of rubber

Compared with prior art, the present invention fill a prescription the loading level that adopts high mixture ratio and than the sulfur consumption of high mixture ratio in conjunction with design, make the gained sizing material not be prone to bloom, guaranteeing the satisfactory whiles of performance such as steel wire extraction, elongation, tensile strength, greatly reduce production cost, processing performance is better, and system component is simple, and starting material are easy to management.
