Problems solved by technology

As we all know, rubber has valuable use value only after being vulcanized. Therefore, a series of physical and mechanical properties of rubber can be greatly improved by suitable vulcanization ingredients in the rubber formula. The existing wear-resistant rubber vulcanizers can improve the mechanical properties of rubber. There are still deficiencies in performance, high temperature resistance, aging resistance and reduction of compression set, which need to be further improved to increase the service life of wear-resistant rubber

Embodiment 1

[0014] A kind of wear-resistant type nano composite rubber, its preparation method comprises the following steps:

[0015] Step 1, with 100 parts of EPDM raw rubber, 25 parts of hyperbranched phosphoramide modified SBA-15 nanomaterials, 15 parts of turpentine, 6 parts of zinc oxide, 40 parts of carbon black and 1.5 parts of N-phenyl-β -Naphthylamine is mixed and kneaded at a temperature of 60°C and a roller spacing of 2 mm to obtain a modified EPDM masterbatch;

[0016] Step 2. After parking the modified EPDM masterbatch for 8 hours, mix it with 15 parts of sulfur and 3 parts of dicumyl peroxide, and mix again at room temperature to obtain a modified EPDM rubber compound ;

[0017] Step 3. After the modified EPDM rubber compound is parked for 24 hours, use a vulcanizer to measure the positive vulcanization time of the modified EPDM rubber compound at a temperature of 170°C. After determining the positive vulcanization time, mix The rubber is vulcanized at a temperature of 17...

Embodiment 2

[0023] The difference from Example 1 is that in step 1, 80 parts of EPDM raw rubber, 20 parts of hyperbranched phosphoramide modified SBA-15 nanomaterials, 10 parts of turpentine, 6 parts of zinc oxide, 40 parts of carbon black and 1.5 parts of N-phenyl-β-naphthylamine were mixed and kneaded at a temperature of 60 ° C and a roller spacing of 2 mm to obtain a modified EPDM rubber masterbatch;

[0024] All the other steps are the same as in Example 1.

Embodiment 3

[0026] The difference from Example 1 is that in step 1, 70 parts of EPDM raw rubber, 15 parts of hyperbranched phosphoramide modified SBA-15 nanomaterials, 5 parts of turpentine, 6 parts of zinc oxide, 40 parts of carbon black and 1.5 parts of N-phenyl-β-naphthylamine were mixed and kneaded at a temperature of 60 ° C and a roller spacing of 2 mm to obtain a modified EPDM rubber masterbatch;

[0027] All the other steps are the same as in Example 1.

Abstract

The invention discloses wear-resistant nano-composite rubber. The wear-resistant nano-composite rubber takes a mixture of raw ethylene propylene diene monomer (EPDM) rubber, a hyperbranched phosphamide modified SBA-15 nanomaterial, turpentine, zinc oxide, carbon black and N-phenyl-beta-naphthylamine as a main raw material; the nano-composite rubber contains the hyperbranched phosphamide modified SBA-15 nanomaterial; the hyperbranched phosphamide modified SBA-15 nanomaterial has high surface activity and fire resistance, thus having higher dispersity, fire resistance and surface tension; therefore, the modified nano-composite rubber has higher wear resistance.

Description

technical field [0001] The invention relates to a wear-resistant nano-composite rubber, which belongs to the field of polymer materials. Background technique [0002] When rubber is exposed to harsh environments for a long time, the molecular chain will be destroyed or further cross-linked, resulting in embrittlement or softening. Therefore, friction-resistant rubber has been widely used in various industries, such as EPDM rubber, because Its main chain is composed of chemically stable saturated hydrocarbons, and only contains unsaturated double bonds in the side chains, so it has excellent high temperature resistance, friction resistance and aging resistance, and can be widely used in automotive parts, wire and cable protection sleeves and seals etc. As we all know, rubber has valuable use value only after being vulcanized. Therefore, a series of physical and mechanical properties of rubber can be greatly improved by suitable vulcanization ingredients in the rubber formula...
