Embodiment 1

[0016] Example 1: First, 500g of powdered activated carbon of 100 mesh, 150g of mesophase pitch of 100 mesh, and 50g of tetra-n-butyl titanate were mixed on a high-speed mixer for 15 minutes to prepare pre-mixed powder; then the pre-mixed powder was put into the ball mill Add 200ml of ethanol and grind and react for 15 hours; the ground mixture is aged and dried at room temperature for 50 hours and crushed to 60 mesh; the above powdery mixture is added to the mold, preformed by cold pressing at 5MPa, and then heated When it reaches 280°C, start pressurization and molding, the pressure is 50MPa, keep it at this pressure for 30 minutes, then stop heating and natural cooling; then the obtained block material is carbonized in a high temperature furnace, nitrogen is selected as the protective gas, and the carbonization heating rate is 1°C / min, the carbonization temperature is 900°C; when the temperature reaches 900°C, the vacuum reaches 2Pa, and the pressure is kept for 2 hours; then...

Embodiment 2

[0017] Example 2: First, 1000 g of powdered activated carbon with 200 mesh, 200 g of mesophase pitch with 100 mesh, and 100 g of tetra-n-butyl titanate were mixed on a high-speed mixer for 10 minutes to prepare pre-mixed powder; then the pre-mixed powder was put into the ball mill Add 300ml of ethanol and grind and react for 5 hours; the ground mixture is aged and dried at room temperature for 100 hours and crushed to 100 mesh; the above powdery mixture is added to the mold, preformed by cold pressing at 3MPa, and then heated When it reaches 300°C, start pressurization and molding, the pressure is 100MPa, keep it for 30 minutes at this pressure, then stop heating and cool naturally; place the obtained block material in a high-temperature furnace for carbonization, select nitrogen as the protective gas, and the carbonization heating rate is 0.5 ℃ / min, the carbonization temperature is 800℃; when the temperature reaches 800℃, vacuumize to 1Pa, keep the pressure for 1 hour; then dec...

Embodiment 3

[0018] Example 3: First, 2,000 g of 100 mesh powdered activated carbon, 400 g of 100 mesh mesophase pitch, and 200 g of tetra-n-butyl titanate were mixed on a high-speed mixer for 15 minutes to prepare pre-mixed powder; then the pre-mixed powder was put into the ball mill Add 600ml of ethanol and grind and react for 20 hours; the ground mixture is aged and dried at room temperature for 100 hours and crushed to 60 mesh; the above powdery mixture is added to the mold, preformed by cold pressing at 5MPa, and then heated When it reaches 300°C, start pressurization and molding, the pressure is 100MPa, keep it for 30 minutes at this pressure, then stop heating and cool naturally; place the obtained block material in a high-temperature furnace for carbonization, select nitrogen as the protective gas, and the carbonization heating rate is 0.5 ℃ / min, the carbonization temperature is 850℃; when the temperature reaches 850℃, vacuumize to 1Pa, keep the pressure for 1 hour; then decrease the...

Abstract

The invention discloses a preparation method of self-cleaning active carbon material which is used in the carbon carving process; and the following method is used for preparing the active carbon material: firstly, powder active carbon, a caking agent and an accelerator are mixed together and then shaped by pressing, and then carbonized under high temperature to obtain the active carbon material. With simple processing art and low cost, the invention can produce material with self-cleaning function, and can catalyse and decompose pollutants adsorbed in the pores of the active carbon into water, carbon dioxide and other decomposition products to separate from the surface of the active carbon; so that the active carbon has an infinite adsorption capacity and permanent use life without activation and regeneration; and the active carbon can continuously adsorb and decompose the indoor toxic air. All arts and crafts made of the active carbon not only can beautify the environment, but also can absorb and decompose the indoor toxic air in a long-term and effective way.

Description

Technical field [0001] The invention relates to a preparation method of a self-cleaning activated carbon material used in a carbon carving process. Specifically, an activated carbon block material loaded with nanometer titanium dioxide in the pores was prepared. Background technique [0002] In modern life, people are paying more and more attention to indoor air pollution. For example, when a cigarette is burned, the smoke released contains nicotine, carbon monoxide, aldehydes, amines and other harmful components, which endanger human health. The use of a large number of decoration materials makes our daily spaces contain various harmful and toxic gases, such as: formaldehyde, benzene, toluene, carbon monoxide, carbon dioxide, sulfur dioxide, hydrogen sulfide, nitrogen oxides, ammonia, methane, etc. These toxic gases have greatly endangered people's health, and can even cause many diseases and cause cancer. Relevant data show that 2.8 million people die from indoor environment...
