Experimental example 1 adhesion Strength test
The adhesion strength is stress required for breaking the interface between the adhesive and the adherend or the vicinity thereof in the adhesive material under the action of external force, and is also called adhesive strength. The bonding strength may be classified into shear strength, tensile strength, uneven tear strength, peel strength, compression strength, impact strength, bending strength, torsional strength, fatigue strength, creep strength, and the like, depending on the stress applied to the bonded joint. The adhesives of examples 1 to 4 and comparative examples 1 to 2 were subjected to the measurement of tensile strength and shear strength.
1. Determination of tensile Strength
Measurement of rubber-to-metal bond tear Strength: the thickness of the rubber is (2 +/-0.3) mm, and the size of a bonded test piece is as the adhesive 180-degree peel strength test method in GB/T2790-1995 standard. The test piece is bonded according to the requirements of the process conditions, and the dislocation of the bonding surface is not more than 0.2 mm. During testing, the test piece is mounted on a fixture, the position is adjusted to ensure that the force application direction is vertical to the bonding surface, the test piece is stretched at the loading speed of (50 +/-5) mm/min, the maximum load during damage is recorded, and the pull-off strength sigma is calculated according to the following formula and has the unit of MPa
σ＝F/A
In the formula: f is the load when the test piece is damaged;
a-bonding area, a ═ d 2/4.
The number of the test pieces is not less than 5, the test pieces are not less than 60% of the original number after being subjected to selection, and the arithmetic mean value is taken, and the allowable deviation is +/-10%.
The tensile strength results of the adhesives of examples 1-4 and comparative examples 1-2 are shown in table 1 below.
2. Determination of shear impact Strength of adhesive
Shear impact strength is the work consumed per unit area of the adhesive bond when the test piece is broken by a shear impact load at a certain speed, and the unit is J/m2And (4) showing. The shear impact strength of the adhesive is determined according to the GB/T6328-1986 standard.
The principle is as follows: a test piece formed by 2 test blocks in a bonded manner is subjected to a shear impact load at a certain speed at a bonded surface, the work consumed when the test piece is damaged is measured, and the shear impact strength is calculated according to the shear impact destructive force born by a unit bonded area. Test piece-a block-shaped adherend having a predetermined shape, size, and accuracy. Sample-a spare part is made by gluing an upper test block and a lower test block under certain process conditions. Impact height-the distance from the blade to the upper surface of the lower test block when the pendulum edge strikes the test block. The tensile strength results of the adhesives of examples 1-4 and comparative examples 1-2 are shown in table 1 below.
3. Evaluation of adhesion: the adhesion was evaluated using the corresponding actual components, i.e. the wire bead and the rubber adhesion, the quality "no problem" being indicated by "O" and the quality defect being indicated by "X". . The test piece used in the experiment is 45 ℃ steel with the specification of 50 multiplied by 5 mm.
TABLE 1
As can be seen from Table 1 above, the tear strength of examples 1-4 reached 21-23MPa, and the shear impact strength reached 40-42 MPa; in comparative example 1, the solute only contains coumarone, the tear strength is only 14Mpa, the shear impact strength is only 30Mpa, and the tear strength is obviously lower than that of the bead wire adhesive in the embodiments 1-4; in comparative example 2, the solute only contains benzotriazole, the tear strength is only 7Mpa, and the shear impact strength is only 18Mpa, which is obviously lower than that of the bead wire adhesive in the embodiments 1-4. Therefore, in the bead wire adhesives of the embodiments 1 to 4, the coumarone and the benzotriazole have synergistic bonding effect, and the adhesive force is far greater than that of the coumarone single component in the comparative example 1 or that of the benzotriazole single component in the comparative example 2.
Experimental example 2 testing of anti-corrosive Properties of bead wire adhesive
1. Salt spray corrosion test for detecting antirust performance of tire bead steel wire adhesive
(1) The test pieces coated with the bead wire adhesives of examples 1 to 4 and the adhesives of comparative examples 1 to 2 were placed in a salt spray test box under specified test conditions, and the degree of corrosion of the test pieces was evaluated after a test time according to the product specification requirements.
(2) The test conditions are as follows: temperature in the salt spray box: 35 ± 1 ℃, concentration of saline solution: 5 plus or minus 0.1 ℃; continuously spraying for 8h in the test, and cooling for 16h for one period;
(3) the test piece is vertically hung on the test piece bracket of the salt spray test box;
(4) test standards: reference is made to the SH/T0081-91 test method.
(5) Each experimental group was repeated three times, and the arithmetic mean of the corrosion degrees of the test pieces of each experimental group was rounded to an integer expressed as SH/T0217 in terms of corrosion scale. The test piece adopted in the experiment is 45 ℃ steel with the specification of 50 multiplied by 5mm, and the test result is shown in the following table 2: wherein "level/period (days)" means: the "+" - "symbol indicates a bias towards either the upper or lower limit;
TABLE 2
As can be seen from table 2, the bead wire adhesives of examples 1-4 have a salt spray corrosion test result with a corrosion rating of substantially 0, i.e. substantially no corrosion during 7 days of the cycle; whereas comparative examples 1-2 were all on a scale of 1-2. Thus, in the bead wire adhesives of the embodiments 1 to 4, coumarone and benzotriazole have synergistic corrosion resistance, and the corrosion resistance is far greater than that of the coumarone single component in the comparative example 1 or that of the benzotriazole single component in the comparative example 2.
2. Saline water immersion test for detecting antirust performance of tire bead steel wire adhesive
The test pieces coated with the bead wire adhesives of examples 1 to 4 and the adhesives of comparative examples 1 to 2 were vertically placed in a constant-temperature water bath of 5% ± 0.1% sodium chloride solution (PH 8.0-8.2) at a predetermined temperature for immersion test, and after immersion for 68 hours, the coated materials were removed to inspect the corrosion of the test pieces. Each experimental group was repeated three times, specifically using the test standard of "aqueous salt immersion test for antirust oil" (SH/T0025) -1999 ".
TABLE 3
As can be seen from Table 3, the test pieces were not substantially corroded in the salt spray corrosion test results of the bead wire adhesives of examples 1 to 4; whereas comparative examples 1-2 all had a greater degree of corrosion. Thus, in the bead wire adhesives of the embodiments 1 to 4, coumarone and benzotriazole have synergistic corrosion resistance, and the corrosion resistance is far greater than that of the coumarone single component in the comparative example 1 or that of the benzotriazole single component in the comparative example 2.
