Problems solved by technology

[0004] In addition, scholars have inserted ionic liquids into kaolinite layers to form nanostructures, which are widely used in electrode modification, catalysts, and detection of anions. Ionic liquid intercalated kaolinite has good thermal stability, electrical conductivity and optical properties. However, the preparation method of ionic liquid intercalated kaolinite abroad is single, and the cycle is long and the process is cumbersome. In the present invention, it is improved and simplified. The experimental process is simplified, the reaction time is shortened, and a better intercalation effect can be obtained at the same time

Embodiment Construction

[0025] A kind of anticorrosion natural rubber material, it is made up of the raw material of following weight part:

[0026] Sodium diacetate 1, natural rubber 100, kaolinite 20, dimethyl sulfoxide 400, methanol 900, N-methylimidazole 70, ethyl bromide 100, nano silicon oxide 4, coconut acid diethanolamide 2, borax 3. Sulfur 1, methyl heptenone 1, calcium propionate 3, diethyl phthalate 7, 2-mercaptobenzimidazole 0.3, antioxidant AW1.

[0027] A kind of preparation method of described anticorrosion natural rubber material, comprises the following steps:

[0028] (1) Grind the above kaolinite into fine powder, mix with sodium diacetate and calcium propionate, stir evenly, add to distilled water 1.6 times the weight of the mixture, add dimethyl sulfoxide, and use a magnetic stirrer at room temperature Stir for 70 hours, filter with suction, wash the filter cake with absolute ethanol, and dry at 60°C for 20 hours to obtain a methyl kaolinite compound;

[0029] (2) Add the above...

Abstract

The invention discloses an anticorrosive natural rubber material. The anticorrosive natural rubber material is prepared from, by weight, 1-2 parts of sodium diacetate, 100-140 parts of natural rubber, 20-30 parts of kaolinite, 400-500 parts of dimethyl sulfoxide, 900-1000 parts of methanol, 70-80 parts of N-methyl imidazole, 100-120 parts of bromoethane, 4-6 parts of nano silicon dioxide, 2-3 parts of cocinic acid diethanolamide, 3-5 parts of borax, 1-1.6 parts of sulfur, 1-2 parts of methyl heptenone, 3-4 parts of calcium propionate, 7-9 parts of diethyl phthalate, 0.3-1 part of 2-mercapto benzimidazole and 1-2 parts of a stabilizer AW. The sodium diacetate, the calcium propionate and the like are added into the rubber material to serve as anticorrosive additives, the corrosion resistance performance of a finished product is effectively improved, and the service life of rubber is delayed.

Description

technical field [0001] The invention relates to the technical field of rubber, in particular to an anti-corrosion natural rubber material and a preparation method thereof. Background technique [0002] Kaolinite is one of the clay minerals of kaolin (kaolinite, dickite, nacre, halloysite, etc.) with l:l layered structure, composed of SiO4 tetrahedral layer and AlO2(OH)4 octahedral layer. 1:1 superimposed to form an asymmetric layered structure, thus establishing a large stack of dipoles, the interlayers are connected by (Al—O—H…O—Si) hydrogen bonds, and the interlayer distance is about 072nm. There is no isomorphic replacement in the crystal lattice, and the charge in the interlayer domain is basically balanced, so that cations cannot be adsorbed in its two-dimensional layer. In addition, due to the interaction of hydrogen bonding force and van der Waals force between layers, it has a considerable Cohesion, so the crystal layers are tightly connected and stable in performan...
