In the preferred embodiment of the present invention, the method 1 for preparing an activated carbon substrate with multiple functions comprises the following steps S1 to S5:
preparation of S1 raw material: dissolving a water-insoluble binding agent, wherein the water-insoluble binding agent is dissolved in water before being ripened, and is not dissolved in water after being ripened, so that the water-insoluble binding agent cannot be dissolved at normal temperature, namely, the step of preparing raw materials before the water-insoluble binding agent is ripened), and adding a large amount of water for blending to form a binding solution after dissolving; the bonding of the activated carbon to the substrate requires bonding by a binder, and the present invention uses a water-insoluble binder; before mixing the water-insoluble binding agent and the activated carbon, dissolving the water-insoluble binding agent and mixing the water-insoluble binding agent and the water to form a pasty binding solution; the water-insoluble binding agent is the best water-insoluble binding agent which does not contain formaldehyde and meets the requirements of environment protection and ecological protection, and the water-insoluble binding agent which achieves the highest environmental protection standard and has zero formaldehyde content is the best environment-friendly water-insoluble binding agent.
S2 adding activated carbon: adding activated carbon into the combined solution, stirring and mixing to ensure that the activated carbon can be attached to the combined solution to form activated carbon solution doped with activated carbon powder B; since activated carbon has a property and function of highly strongly adsorbing surrounding substances, the activated carbon must strongly adsorb the binding solution and be coated therein during mixing and stirring.

S4 high-temperature heating and ripening: the temperature and time can be mainly used for leading the moisture of the activated carbon solution in the base material to reach the temperature (heated to 90-130 ℃) capable of forming water vapor due to the temperature rise, when the moisture is evaporated to form the water vapor upwards, the moisture can flush out a plurality of gas channels 312 in the base material, and the gas channels 312 are used as vent holes 311 prepared in the base material.
S5 rapid cooling and shaping: the substrate with the gas channel 312 is rapidly cooled, the gas channel 312 is cooled and shaped and retained to form the vent hole 311 of the substrate, and since the particle size of the activated carbon is larger than that of water molecules, the aperture of the vent hole 311 is naturally smaller than that of the activated carbon, so that the activated carbon does not flow out from the vent hole 311 even if the substrate is washed by water, thereby obtaining the activated carbon substrate 3 with high ventilation and vent hole 311, repeated washing without flowing out the activated carbon, excellent stability, and high deodorization and toxicity filtration absorption rate (the gas channel 312 can refer to fig. 5, fig. 5 is a partial enlarged schematic view of the gas channel cross section of the activated carbon substrate with multiple functions in one embodiment of the invention).

The invention discloses an active carbon substrate integrating multiple functions and a preparation method thereof, which have the following advantages:
1. the activated carbon is combined with the substrate by using a solution prepared by a water-insoluble binding agent, so that the activated carbon substrate produced by the preparation method can be ensured to have longer adhesion with the substrate because the water-insoluble binding agent is insoluble in water at normal temperature during washing, and the activated carbon cannot be dissolved by water to cause the loss of water along with the activated carbon; and the ventilation holes are formed by utilizing gas channels of water vapor, and the particle size of the activated carbon is larger than the pore size of the ventilation holes formed by the water vapor, so that the activated carbon has no chance of loss in washing.
2. The water-insoluble binding agent used in the preparation method can be a formaldehyde-free component serving as an optimal environment-friendly raw material, the preparation method is a physical reaction and a non-chemical reaction, and not only is the reaction time relatively short, but also hydrochloric acid or formalin is not needed to be used as an activator or a catalyst, so that the binding solution can be ensured not to be excessively viscous when the preparation method is carried out, more perfect mass production can be realized, the environmental pollution caused by chemical agents can be ensured, and an additional deacidification step is not needed to remove chemical solvents needed by the chemical reaction.
3. The active carbon substrate of the invention has the functions of deodorization, poison filtration, high adsorption, high water absorption and high sweat absorption of the active carbon, and can achieve the effect of high ventilation through the ventilation holes of the substrate layer inside.
