Embodiment 1

[0018] Example 1: Add 1.5kg of clean water and 100g of natural rubber latex into a 3L four-necked bottle, then add 0.5g of nonionic surfactant and 0.5g of cationic surfactant respectively, and fully stir. Take 0.5 g of graphene oxide and make it into 1 mg / mL aqueous solution, sonicate for 1 h, and add it into the reaction system. Finally, 1 g of peroxidation initiator was added. Under the irradiation of stirring and ultraviolet light (power 1500W), the temperature is controlled below 10° C., and the chlorination reaction is carried out by chlorine gas. When the amount of chlorine gas introduced reaches 30% of the required amount, the temperature rises and enters the second stage, and the temperature is controlled at 10-40°C. When the amount of chlorine gas introduced reaches 80% of the required amount, the temperature rises and enters the third stage. Before the maximum temperature does not exceed 130 ° C, the remaining chlorine gas is introduced. The total amount of chlorin...

Embodiment 2

[0019] Embodiment 2: similar to embodiment 1, take 100g of natural rubber latex as the benchmark amount, and the difference is to add 1.0g of graphene oxide. The other steps were the same as in Example 1 to obtain a graphene-modified chlorinated rubber composite material with a graphene mass fraction of 1%.

Embodiment 3

[0020] Embodiment 3: similar to embodiment 1, take 100g natural rubber latex as the benchmark amount, and difference is to add 1.5g graphene oxide. The other steps were the same as in Example 1 to obtain a graphene-modified chlorinated rubber composite material with a graphene mass fraction of 1.5%.

Abstract

The invention relates to a graphene modified chlorinated rubber composite material and a preparation method thereof. The graphene modified chlorinated rubber composite material comprises natural latex, non-ionic surface active agents, cationic surface active agents, peroxidation initiators and graphene oxide. Based on chlorinated rubber preparation by a water phase suspension method, the graphene oxide with fine water solubility is added into a system and synchronously restored into graphene by irradiation of ultraviolet light in the reaction process, and finally, the graphene modified chlorinated rubber composite material with fine dispersity is obtained. Problems caused by organic solvents are avoided as chlorinated rubber is prepared by the water phase suspension method. The graphene oxide serving as the oxidation state of the graphene contains a large number of oxygen-containing functional groups and has excellent water solubility. The graphene oxide is restored into the graphene along with synthesis of the chlorinated rubber by irradiation of the ultraviolet light, and finally, the graphene modified chlorinated rubber composite material with excellent performances is obtained.

Description

technical field [0001] The invention belongs to the field of new materials, in particular to a method for preparing a graphene-modified chlorinated rubber composite material. Background technique [0002] Chlorinated rubber is a natural rubber derivative formed by chlorination of natural rubber. It is odorless, non-toxic and non-irritating to the human body. Chlorinated rubber has the advantages of excellent film-forming properties, adhesion, abrasion resistance, corrosion resistance and flame retardancy, and is widely used in paints, coating pigments and other fields. At present, chlorinated rubber is mostly produced with carbon tetrachloride as a solvent, but due to the high cost of the solvent method, and some solvents such as carbon tetrachloride are harmful to the human body, and volatiles pollute the environment and residual solvents and other defects, and use access is strictly restricted. In recent years, there has been a new upsurge in the research of chlorinated ...
