Problems solved by technology

[0003] In the prior art, the adhesives commonly used in tires have poor adhesion performance. When the inner surface of the tire adheres to the noise absorber, the noise absorber will fall off after a short period of time. Moreover, The fluidity of commonly used adhesives is either too large or too small, which is not convenient for adhesion operation. Therefore, in order to solve the problems of poor adhesive adhesion and inconvenient adhesion operation, there is an urgent need for an adhesive that can satisfy the above two conditions at the same time. Adhesives for use

Embodiment 1

[0044] A kind of adhesive, described adhesive comprises the component of following mass parts:

[0045] Rubber compound 168.55phr

[0046] Adhesive resin 25-40phr

[0047] Gasoline 250-450phr

[0048] Wherein said rubber compound comprises the component of following mass parts:

[0049] Butyl rubber 100phr

[0050] N660 50phr

[0051] Other systems 18.55phr.

[0052] The butyl rubber is halogenated butyl rubber, and the halogenated butyl rubber is one or more of chlorinated butyl rubber or brominated butyl rubber.

[0053] Such other systems include activators, vulcanizing agents, accelerators, and scorch retarders.

[0054] The binder resin is at least one of hydrocarbon resin, terpene resin and indene resin.

[0055] The gasoline is one of No. 93 gasoline, No. 97 gasoline and No. 120 gasoline; No. 120 gasoline is preferred for gasoline.

[0056] The viscosity of the adhesive at room temperature is 20000-40000 centipoise.

[0057] For details, see Table 1 below:

Embodiment 2

[0070] A method for preparing an adhesive, comprising the steps of:

[0071] S1. Preparation of mixed rubber in M1 section

[0072] (1) Start the internal mixer to preheat, then take 2 / 3 of 50phrN660 and 100phr butyl rubber into the preheated internal mixer, press the top bolt of the internal mixer for 60s, and then lift the top bolt 10s;

[0073] In (1) of the step S1, before adding the N660 and butyl rubber, it is necessary to adjust the rotational speed of the internal mixer to 40 r / min. (2) Add the remaining 1 / 3 of 50phrN660, press the top bolt of the internal mixer for 30s, and then lift the top bolt for 10s;

[0074] (3) Finally, when the top bolt is pressed for 90s or the temperature reaches 145°C, the rubber is discharged to obtain the mixed rubber of the M1 stage;

[0075] Before weighing N660 and butyl rubber, start the internal mixer for preheating. During the preheating process of the internal mixer, the weighing and proportioning of N660 and butyl rubber can be...

Abstract

The invention discloses an adhesive and a preparation method thereof. The adhesive comprises the following ingredients (by mass): 168.55 phr of a rubber compound, 25-40 phr of bonding resin and 250-450 phr of gasoline. The rubber compound comprises the following ingredients (by mass): 100 phr of butyl rubber, 50 phr of N660 and 18.55 phr of other systems. According to the invention, the rubber compound, bonding resin and gasoline are adopted, and the mass ratio of the rubber compound to bonding resin to gasoline is strictly controlled within the range of 1:0.15-0.24: 1.48-2.67. Thus, it can beensured that fluidity of the prepared adhesive is appropriate and viscosity of the adhesive at room temperature is within the range of 20,000-40,000 centipoises. In addition, when the prepared adhesive is in use, the curing time as required is proper, the adhesive effect is good, and the adhesive can meet the use requirement.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to an adhesive and a preparation method thereof. Background technique [0002] At present, the adhesive used for tire bonding needs to comprehensively consider the movement of the tire during use and the adhesive effect of the adhesive itself. Considering that during the driving process of the tire, its adhesion part will undergo continuous and repeated deformation as the tire runs. When it is necessary to adhere inside the tire, it is necessary to consider the firmness and durability of the adhesion. [0003] In the prior art, the adhesives commonly used in tires have poor adhesion performance. When the inner surface of the tire adheres to the noise absorber, the noise absorber will fall off after a short period of time. Moreover, The fluidity of commonly used adhesives is either too large or too small, which is not convenient for adhesion operation. Therefore, in order to solve...
