Problems solved by technology

[0002] Thus affecting the overall noise reduction effect
As more and more cars cancel the spare tire, the original car is equipped with a tire sealant. When the owner uses the tire sealant to repair the tire in an emergency, the traditional car tire silent cotton is bonded to the inside of the car tire, which will inevitably cause the car owner to use the tire sealant. When the tire is repaired after the tire is damaged, cut off the silent cotton of the damaged part. The traditional silent cotton tire, the silent cotton will absorb the tire sealant fluid, which will affect the repair effect and the cleaning is cumbersome, and the follow-up will affect the noise reduction effect of the silent cotton

Embodiment 1

[0022] S1: weigh 10% of SBS rubber, 20% of methylene chloride, 30% of rosin resin, 20% of terpene resin, and 20% of 6# solvent oil according to the weight ratio of the components;

[0023] S2: take a reactor and control the temperature in the reactor to be 10-25°C, add methylene chloride and 6# solvent oil into the reactor first, stir evenly and then slowly add SBS rubber to the reactor while stirring;

[0024] S3: keep stirring under the condition that the reaction kettle is closed and the temperature in the kettle is 10-25 ℃, and then add rosin resin and terpene resin to the reaction kettle after the SBS rubber is dissolved;

[0025] S4: test the semi-finished product prepared by S3, if the test is qualified, proceed to the next step;

[0026] If it is unqualified, adjust the ratio for re-distribution, and then proceed to the next step if it is qualified.

[0027] S5: add silane coupling agent, anti-aging agent, catalyst and water absorbing agent to the semi-finished produc...

Embodiment 2

[0031] The preparation method of Example 2 is exactly the same as that of Example 1. For the sake of simplicity, the same content will not be repeated here. The proportioning ratio of each component of Example 2 is as follows: SBS rubber 15%, methylene chloride 15%, rosin Resin 30%, terpene resin 20%, 6# solvent oil 20%.

[0032] Example 2:

Embodiment 3

[0033] The preparation methods of Example 3 and Example 1 are exactly the same. For the sake of simplicity, the same content will not be repeated here. The proportioning ratio of each component of Example 2 is as follows: SSBS rubber 15%, methylene chloride 20%, rosin Resin 30%, terpene resin 20%, 6# solvent oil 25%.

[0034] The performance of the adhesive obtained in conjunction with Examples 1-3 is as follows:

[0035] 1) Color: beige or white or light brown.

[0036] 2) Odor: The pine scent is bland and not pungent.

[0037] 3) Brush the glue once, and use the pressure of 0.4MPa to press continuously for 3min, the initial adhesion tensile shear strength after 20min is ≥30kPa; the tensile shear strength after 24h is ≥600kPa.

[0038] 4) This product can adapt to the construction under the environment temperature of -20℃~50℃. After solidification, the product can withstand high temperature of 100℃ and low temperature of -40℃.

[0039] 5) The bonding speed is fast, and th...

Abstract

The invention discloses a special adhesive for mute cotton and automobile rims and a preparation method of the special adhesive. The special adhesive comprises the following components in percentage by weight: 5-15% of SBS rubber, 15-20% of dichloromethane, 20-30% of rosin resin, 10-20% of terpene resin and 20-30% of 6 # solvent oil. Compared with the prior art, the tire repairing device has the advantages that the mute cotton is adhered to the rim, after a vehicle owner uses the tire repairing liquid, the tire repairing liquid is almost attached to the inner surface of a tire under the action of centrifugal force, the mute cotton on the rim cannot be influenced, and the user experience is greatly improved; and the mute cotton does not need to be replaced according to the number of times of tire replacement of a university owner. The use cost of a vehicle owner is greatly saved; nVH (Noise Vibration and Harshness) performance of silence cotton is not influenced, and after the silence cotton is adhered to a rim through the adhesive, cavity noise generated in a wheel assembly is remarkably reduced; the adhesive can resist a high-temperature environment of 110 DEG C and an extremely cold environment of-40 DEG C, and meets a temperature range which can be reached by a rim when a vehicle runs.

Description

technical field [0001] The invention relates to the field of adhesives, in particular to a special adhesive for silent cotton and automobile wheel rims and a preparation method thereof. Background technique [0002] This affects the overall noise reduction effect. As more and more cars cancel the spare tire, the original car is equipped with tire repair fluid. When the car owner uses the tire repair fluid to repair the tire in an emergency, the traditional car tire mute cotton is bonded to the inside of the car tire, which will inevitably cause the car owner to suffer When the tire is repaired after the tire is damaged, cut off the damaged part of the silent cotton. For the traditional silent cotton tire, the silent cotton will absorb the tire repair fluid, which will affect the repair effect and the cleaning is cumbersome, and the noise reduction effect of the silent cotton will be affected later. SUMMARY OF THE INVENTION [0003] The present invention aims to solve the ...
