Embodiment 1

[0043] A kind of rubber additive, its chemical structural formula is:

[0044]

[0045] The preparation method of above-mentioned metallic soap, comprises the following steps:

[0046] (1) Add 1 L of distilled water and 128.18 g of sodium ricinoleate (purity ≥ 90%, purchased from TCI) into a 2 L beaker. The above mixture was heated to 90 °C and stirred vigorously for 1 hour until the solution was completely transparent. (Solution A)

[0047] (2) Another 2L beaker was taken, and 1L of distilled water and 94.8g of potassium aluminum sulfate dodecahydrate (purity ≥ 99%, purchased from Aladdin) were added into it. The above mixture was heated to 90 °C and stirred vigorously for 1 hour until the solution was completely transparent. (Solution D)

[0048] (3) Finally, with the solution A being vigorously stirred, the solution D was slowly poured into the solution A at a speed of 10 mL / s to obtain a milky white solid product. The resulting white solid product was washed 5 time...

Embodiment 2

[0050] A kind of rubber additive, its chemical structural formula is:

[0051]

[0052] The preparation method of above-mentioned metallic soap, comprises the following steps:

[0053] (1) Add 1 L of distilled water and 4 g of solid sodium hydroxide (purity ≥ 97%, purchased from Aladdin) in a 2 L beaker. After the sodium hydroxide was completely dissolved, 27.4 g of 4-aminobenzoic acid (purity ≥ 98%, purchased from Aladdin) was added. The above mixture was heated to 90 °C and stirred vigorously for 1 hour until the solution was completely transparent. (Solution B)

[0054] (2) Add 1L of distilled water and 64.9g of sodium ricinoleate (purity ≥ 90%, purchased from TCI, and can be formed by reacting ricinoleic acid and sodium carbonate at a molar ratio of 2:1) into a 2L beaker. The above mixture was heated to 90 °C and stirred vigorously for 1 hour until the solution was completely transparent. (Solution A)

[0055] (3) Another 2L beaker was taken, and 1L of distilled wa...

[0058] A kind of rubber additive, its chemical structural formula is:

[0059]

[0060] The preparation method of above-mentioned metallic soap, comprises the following steps:

[0061] (1) Add 1 L of distilled water and 6.87 g of solid sodium hydroxide (purity ≥ 97%, purchased from TCI) into a 2 L beaker. After the sodium hydroxide was completely dissolved, 116.37 g of erucic acid (purity ≥ 85%, purchased from Aladdin) was added. The above mixture was heated to 90 °C and stirred vigorously for 1 hour until the solution was completely transparent. (Solution A)

[0062] (2) Another 2L beaker was taken, and 1L of distilled water and 81.52g of potassium aluminum sulfate dodecahydrate (purity ≥ 99%, purchased from Aladdin) were added into it. The above mixture was heated to 90 °C and stirred vigorously for 1 hour until the solution was completely transparent. (Solution D)

[0063] (3) Finally, with the solution A being vigorously stirred, the solution D was slowly poured in...

Abstract

The invention relates to a rubber additive as well as preparation and application thereof. The chemical structural formula of the rubber additive is as shown in the specification, in the formula, M is a metal of which the oxidation state is +3 or +4; R1 is an aliphatic chain of C5-C50 of which a plurality of functional groups are substituted; the substituted functional groups on the chain of R1 include hydroxyl, double bonds or an epoxy group; R2 and R3 are aliphatic chains with 0-50 carbon atoms; R4 is a aromatic ring compound or a nitrogen heterocyclic ring compound; the amino can be connected with R2, R3 and R4 in modes of primaquine, parahelium and tertamino; n is a positive integer not smaller than 1; x is 0 or 1; y is 1 or 2; x+y=2. When the rubber additive is adopted to prepare rubber, the tension strength, the anti-sliding property and the like of the rubber can be remarkably improved.

Description

technical field [0001] The invention relates to the field of tire rubber additives, in particular to a rubber additive and its preparation and application. Background technique [0002] In the tire industry, rubber formulations are designed with a balance of properties such as tear strength, rolling resistance and traction. In general, changing a component to improve one or more of these properties often results in a decrease in the other properties. Rubber materials have good elasticity and chemical stability. The addition of reinforcing agent can significantly improve the physical and mechanical properties of rubber, improve its physical properties such as hardness, tensile strength, shear strength and wear resistance, and also change the viscoelasticity of rubber, making its rheological behavior more complex . [0003] The research on aluminate soap has already started very early. Most metal soaps will form gels when they cool down in hot organic solvents, and the dif...
