Embodiment 1

[0026] First, 100 parts of cellulose derivatives were mixed at 120 ° C for 10 minutes, then 40 parts of carbon black N330, 2 parts of anti-aging agent RD, 3 parts of sulfur and 1 part of accelerator CZ were added, and the mixing was continued for 20 minutes, and then a flat vulcanizer was used. Under the pressure of 15MPa and the temperature of 150°C, vulcanization was carried out for 30min to obtain a sealing material.

Embodiment 2

[0028] First, 100 parts of cellulose derivatives were mixed at 130 °C for 10 minutes, then 35 parts of carbon black N330, 2 parts of antioxidant 2246, 2 parts of sulfur and 0.5 parts of accelerator CZ were added, and the mixing was continued for 20 minutes, and then a flat vulcanizer was used. Under the pressure of 10MPa and the temperature of 160°C for 30min, the sealing material was obtained.

Embodiment 3

[0030] First, 100 parts of cellulose derivatives were mixed at 120°C for 10 minutes, then 30 parts of carbon black N220, 1 part of antioxidant MB, 0.5 part of antioxidant 2246, 3 parts of sulfur and 2 parts of accelerator DTDM were added, and the mixing was continued for 20 minutes. , and then use a flat vulcanizer to vulcanize for 30 minutes at a pressure of 15MPa and a temperature of 160°C to obtain a sealing material.

Abstract

The invention discloses a marine biomass-based pressure-resistant sealing material and a preparation method thereof, and relates to the technical field of sealing materials.The sealing material is prepared from cellulose extracted from seaweed through chemical reaction to prepare a cellulose derivative, and the cellulose derivative is assisted by a reinforcing agent, an anti-aging agent, a vulcanizing agent and an accelerant to prepare the sealing material. The novel application of the cellulose extracted from the seaweed in the field is realized, and the prepared sealing material has good application performance and is especially suitable for sealing occasions with high pressure resistance requirements.

Description

Technical field: [0001] The invention relates to the technical field of sealing materials, in particular to a marine biomass-based pressure-resistant sealing material and a preparation method thereof. Background technique: [0002] Seaweed is a natural marine biomass resource, which is inexhaustible and inexhaustible. my country is a big seaweed producing country, and its output ranks first in the world. It has formed an industrial chain integrating seedling breeding, breeding, processing and sales. Marine biomass materials such as chitin, chitosan, and cellulose extracted from seaweed have the advantages of being clean, environmentally friendly, low in cost, and degradable by seawater, and can quickly replace existing refractory polymer materials and products on a large scale. [0003] Although cellulose extracted from seaweed has a variety of uses, such cellulose cannot be directly processed into sealing materials in the art. In order to broaden the application scope of t...
