Problems solved by technology

[0007] However, along with the above-mentioned advantages, trialkoxymercaptoalkyl-silanes have the disadvantages of increasing the viscosity of the compound and thus making it more difficult to process, impairing wet grip properties, and reducing abrasion resistance
However, it has been found that while improving wet grip and abrasion resistance, this increases viscosity and thereby further exacerbates the problems associated with compound viscosity

Embodiment

[0027] Three control compounds (A-C) and a compound according to the teachings of the present invention (D) were made. More specifically, the first control compound (A) is a compound according to the prior art using a silane coupling agent other than trialkoxymercaptoalkyl-silanes; the second control compound ( B) Same as the first control compound, but using a silane coupling agent of the trialkoxymercaptoalkyl-silane type; and the third control compound (C) is the same as the second control compound , but it uses a large area of ​​silica.

[0028] The compounds were made as follows:

[0029] -First kneading step-

[0030] Before starting the mixing operation, charge the cross-linkable unsaturated chain polymers, silica, carbon black and silane coupling agent into a 230-270 liter tangential rotor mixer until the filling factor is 66-72% .

[0031] In compound D according to the invention, the silane coupling agent is added in the form adsorbed to all carbon black and to d...

Abstract

A method of producing a rubber compound, including a first mixing step of mixing at least one cross-linkable unsaturated-chain polymer base, silica, and a silane coupling agent in the mercaptoalkyl-silane class; and a final mixing step, in which a curing system is added to the mix. The silane coupling agent is used in adsorbed form on dibenzothiazyl disulphide.

Description

technical field [0001] The present invention relates to a tread compound comprising a trialkoxymercaptoalkyl-silane. Background technique [0002] In certain compounds, such as tread compounds, silica has long replaced conventional carbon black due to its advantages in rolling resistance and wet road-holding performance Used as a reinforcing filler. [0003] Silica is used in combination with a silane coupling agent, which bonds with silanol groups to prevent hydrogen bond formation between silica particles and at the same time chemically bonds the silica to polymers. [0004] As silane coupling agents, mercaptoalkyl-silanes have recently been found to further improve the rolling resistance and hydrocarbon emissions of compounds. [0005] In particular, the following proved to be very effective: [0006] SH(CH 2 ) 3 Si(OCH 2 CH 3 )(O(CH 2 CH 2 O) 5 (CH 2 ) 13 CH 3 ) 2 [0007] However, along with the above-mentioned advantages, trialkoxymercaptoalkyl-silanes h...
