Problems solved by technology

[0004] For this reason, problems arise in the rubber composition simply blending an inorganic filler such as silica: the dispersion of the filler is insufficient, and the breaking strength and wear resistance are greatly reduced.
[0008] In addition, Patent Document 13 discloses a rubber composition containing a silane-modified butadiene polymer, but the urethane-modified butadiene polymer at both ends has a polar group in the molecule, and has not yet been disclosed. Obtaining a rubber composition for tires that achieves desired low fuel consumption

Embodiment 1-1

[0117] B-1000 (manufactured by Nippon Soda Co., Ltd., number average molecular weight 1100, (f+g) ) / (e+f+g)=0.9) 100g, toluene 200g, the toluene solution of platinum-1,3-divinyl-1,1,3,3-tetramethyldisiloxane complex (with Platinum atomic meter, 1.6×10 -4 mol) and ammonium bicarbonate 1.3g (1.6×10 -2 Moore). After adding 263 g (1.6 mol) of triethoxysilane dropwise thereto at an internal temperature of 75 to 85° C. over 2 hours, it was stirred at 80° C. for 1 hour. Table 1 shows the results of analyzing the reaction rate of the obtained triethoxysilane by gas chromatography.

[0118] After the stirring was completed, concentrated under reduced pressure and filtered to obtain a brown transparent liquid with a viscosity of 11000 mPa·s and a number average molecular weight of 3900. In terms of the molecular weight of the product and the 1 The average structure determined by the H-NMR spectrum is an organosilicon compound represented by e=2, f=0, g=18 in the above formula (1). ...

Abstract

An organic silicon compound represented by formula (1) makes it possible to significantly lower the hysteresis loss of a cured product when added to a rubber composition and also imparts a rubber composition with which it is possible to realize a desired low-fuel-consumption tire. (In the formula, R1 independently represent a C1-10 alkyl group or C6-10 aryl group, R2 independently represent a C1-10 alkyl group or C6-10 aryl group, f represents a number of 0 or higher, e and g independently represent a number greater than 0, and m represents an integer of 1-3. However, the order of each of therepeating units is arbitrary.)

Description

technical field [0001] The present invention relates to organosilicon compounds, compounding agents for rubber and rubber compositions using the organosilicon compounds, and more specifically, to organosilicon compounds having a polybutadiene skeleton, their production methods, and the use of the organosilicon compounds. Compounding agent for rubber, rubber composition and tire obtained from the rubber composition. Background technique [0002] Sulfur-containing organosilicon compounds are useful as an essential ingredient in the manufacture of tires made of silica-filled rubber compositions. Silica-filled tires have excellent properties in automotive applications, particularly excellent wear resistance, rolling resistance, and wet skid resistance. The improvement of these performances is currently actively researched because it leads to the improvement of the fuel consumption of a tire and the adhesion|attachment. [0003] When improving fuel consumption, it is necessary ...
