Definitions
- the present invention relates to a rubber composition obtained by compounding silica as a reinforcing agent with a gen-based rubber, and more particularly, to a rubber composition having excellent rebound resilience and excellent tensile properties, abrasion properties, and processing properties. It relates to a rubber composition.
- An object of the present invention is to provide a rubber composition exhibiting the above tensile strength and abrasion resistance and having good workability.
- the present inventors have conducted intensive studies to overcome the above-mentioned problems of the prior art, and as a result, in order to increase the affinity between a gen-based rubber and silica, an epoxy group, a hydroxyalkyl group, an alkoxy group If silicone oil having a polar group such as a base is used, the surface treatment of the silicone force with silicon oil is not performed in advance, and the gem is put into a kneading machine such as Banbari. Rubber composition that shows good workability, high rebound resilience and sufficient tensile strength even when batch rubber, silica, and silicone oil having polar groups are added and kneaded. And found that the present invention was completed.
- a rubber composition containing a gen-based rubber and a silica force In (i) 100 to 150 parts by weight of a gen-based rubber, 100 to 150 parts by weight of silica, and (ii) 100 parts by weight of silica, a side chain or a terminal
- the present invention provides a rubber composition characterized by comprising 0.1 to 50 parts by weight of silicone oil having a functional group.
- the gen-based rubber used in the present invention is not particularly limited, and examples thereof include natural rubber (NR), polyisoprene rubber (IR), and emulsified polystyrene-butadiene.
- gen-based rubbers can be used alone or in combination of two or more. Of these, NR, BR, IR, SBR, and SIBR are preferred.
- the mu-viscosity (ML 1 +4,100) of the gen-based rubber used in the present invention is not particularly limited, but is usually from 20 to 150 in view of mechanical strength and workability. Preferably, it is in the range of 30 to 100. However, when the diene polymer rubber is oil-extended and used, the value may exceed 150.
- silica used in the present invention those generally used for compounding general-purpose rubber can be used. Specifically, dry-type white carbon, wet-type white carbon, colloid darica generally used as a reinforcing agent, and sedimentation disclosed in JP-A-62-262838 An example is silica. Among these, wet-process white carbon containing hydrated maleic acid as a main component is preferable.
- the specific surface area of the sheet re Ca is not particularly limited, a nitrogen adsorption specific surface area (BET method) normally 50 ⁇ 4 00 m 2 / g, preferably rather then favored 1 00 ⁇ 250m 2 / g is found that 1 2 is in the range of 0 ⁇ 1 9 0 m 2 / g . If the specific surface area of the die is excessively small, the reinforcing property is inferior. Conversely, if the specific surface area is excessively large, the workability is inferior, and the abrasion resistance and the rebound resilience are not sufficiently improved.
- the nitrogen adsorption specific surface area is a value measured by the BET method according to ASTMD3037-81.
- the proportion of silica used is 100 parts by weight of the gen-based rubber component.
- It is from 10 to 150 parts by weight, preferably from 20 to 120 parts by weight, and more preferably from 40 to 80 parts by weight. If the compounding ratio is too small, the reinforcing property is poor, and if it is too large, the viscosity of the unvulcanized rubber composition increases, resulting in poor processability.
- the silicone oil used in the present invention has a polar side chain or terminal. Characterized by having a group.
- Preferable polar groups include, for example, substituents having at least one type of heteroatom or heteroatom atom group, and heteroatoms such as oxygen atom and sulfur atom. And a nitrogen atom.
- the polar group include, for example, a hydroxyl group, an amino group, a carboxyl group, an oxy group (an ether group or an epoxy group), a carboxy group, an ester group, a snorrefid group, and a disnoriffyl group.
- silicone oil having such a polar group examples include organopolysiloxanes represented by the following general formulas (1) to (3).
- m is usually from 1 to: 10, 0 0, preferably 1 to 1,
- n Represents an integer of from 0000, more preferably from 1 to 500.
- n usually represents an integer of 1 to 100, preferably 1 to 500, and more preferably 1 to 100.
- X represents an organic residue having the polar group.
- the organic residue include an alkyl group, an alkenyl group, an alkynyl group, an aryl group and an alkyl group, and are preferably an alkyl group.
- Specific examples of X For example, a hydroxyalkyl group, an aminoalkyl group, a carboxylalkyl group, an epoxyalkyl group, an alkoxy group, an alkoxyalkyl group, an acyl group, an acylalkyl group, an acyloxy group, an acyloxy group And an alkyl group.
