example 12A to example 12D

[0294] For the preparation of rubbers composed of SBR and granular carbon materials from Examples 1 and 2 or with carbon black N660 Examples 12A to 12D of articles and reference examples

[0295] The carbon material obtained according to Example 1 and Example 2 was introduced as filler material into the rubber mixture and vulcanized with the aid of further additives. The components of the rubber mixture are shown in Table 7.

[0301] Lanxess' SBR solution (sSBR) Buna VSL 4526-0 was used as SBR. The SBR is a copolymer composed of 26% by mass of styrene in addition to butadiene. Its Mooney viscosity is 65ME (ASTM D 1646). Zinc oxide, stearic acid and sulfur were from Fischer Scientific. 2-N-Cyclohexylbenzothiazole sulfenamide (CBS) was from Lanxess. 1,3-Diphenylguanidine (D...

example 2

[0309] Application of the particulate carbon material in Example 2 in combination with a coupling agent (Example 12B) caused a noticeable change. Compared to the reference and 12A, the glass transition temperature of the mixture in Example 12 was shifted up to T g,SBR = -0.48°C. Under conditions of weak dynamic strain (0.5%), the energy loss behavior of mixture 12B is clearly improved relative to the reference with N660, which is seen at lower curve changes in the temperature range above the glass transition temperature.

[0310] It can be seen that the elastomeric material comprising the granular carbon material and coupling agent in Example 2 has a smaller value for tan δ above the glass transition temperature relative to the reference with N660, which is shown by the Relatively reduced sliding friction can be expected in the resulting tire.

[0320] to confirm 14 C content, the material in Example 2 was provided to A.Mickiewicz University Foundation, Poznań Ridiocarbon Laboratory, ul. 46, 61-612 Poznań. The method used is described by the head of the laboratory, Tomasz Goslar, on the institute's website. The main components of lignin are summarized below.

Abstract

The present invention relates to a particulate carbon material that can be produced from renewable raw materials, in particular from biomass containing lignin, comprising: a 14C content that corresponds to that of the renewable raw materials, said content being preferably greater than 0.20 Bq / g carbon, especially preferably greater than 0.23 Bq / g carbon, but preferably less than 0.45 Bq / g carbon in each case; a carbon content in relation to the ash-free dry substance of between 60 ma.% and 80 ma. %; an STSA surface area of the primary particles of at least 5 m2 / g and at most 200 m2 / g; and an oil absorption value (OAN) of between 50 ml / 100g and 150ml / 100g. The present invention also relates to a method for producing said carbon material and to the use thereof.

Description

technical field [0001] The invention relates to a granular carbon material according to claim 1 , a process for the production of said carbon material according to claim 9 and the use of this material in polymer mixtures according to claim 19 . Background technique [0002] There are a wide variety of applications for granular carbon materials. One application is as a filler material for polymers such as elastomers, thermoplastics or thermosets. Fillers are used in the production of rubber articles made of elastomers in order to influence the rubber-side properties of the crosslinked rubber article, which are measured, for example, as tensile strength, hardness, rigidity or breaking strength. Furthermore, product properties such as rolling resistance, wear and wet grip in vehicle tires are thereby adjusted. The influence of the properties of the rubber by the filling material is also referred to as reinforcement. [0003] The most widely used filler materials today are ca...
