Problems solved by technology

The above-mentioned deodorants contain not only some substances such as activated carbon or floor fungicides, but also some inferior chemical synthetic substances. Although they can eliminate pollutants such as formaldehyde to a certain extent, they may also recreate other pollutants, resulting in secondary pollution.

Embodiment Construction

[0011] The present invention is described in detail below in conjunction with embodiment.

[0012] A kind of preparation method of activated carbon air freshener, its raw material is composed by weight ratio: soot carbon black: raw dolomite lime powder = 1: 1, wherein, soot carbon black is the soot charcoal recovered in the lime kiln burning process of bituminous coal Black, the fineness of raw dolomite lime powder is below 40 mesh; according to the above-mentioned raw material ratio, after fully stirring and mixing the soot carbon black and raw dolomite lime powder, add water accounting for 28% of the total weight of the raw materials and mix evenly, and generate heat through self-reaction Finally, the black powdery mixture is obtained as the finished product. In order to solve the pollution of transportation and packaging, the powdery mixture can also be humidified and turned into granules by rolling on a mechanical turntable, and dried (extrusion is avoided) to become granu...

Abstract

The invention relates to a preparation method of an air freshener, in particular to a preparation method of an air freshener of activated carbon. The air freshener comprises the following components by weight proportion: dust carbon black: raw calcined dolomite powder=1:1, wherein the dust carbon black is recovered in the process of using bituminous coal in a lime kiln to bake lime and the fineness of the raw calcined dolomite powder is below 40 meshes; according to the proportion of the materials, the dust carbon black and the raw calcined dolomite powder are mixed fully, water with proper amount is added, the obtained mixture is mixed evenly, and heats by self reaction so as to obtain black powder mixture, namely, the finished product. The dust carbon black has small particle size of activated carbon, light weight, large specific surface area and strong absorption power, can have good and fast purifying effect to the air, and has low recovery cost, thus providing a material source which can prepare the activated carbon without wood, coal carbonization and activation.

Description

Technical field: [0001] The invention relates to a preparation method of an air freshener, in particular to a preparation method of an activated carbon air freshener. Background technique: [0002] Known air fresheners are also called deodorants and mainly contain three classes: chemical sprays, solid adsorptions and smears. Chemical sprays are mainly used after decoration; solid adsorbents can adsorb indoor harmful gases; smears are aimed at the inner wall panels of furniture or the surface of indoor walls. The above-mentioned deodorants contain not only some substances such as activated carbon or floor fungicides, but also some inferior chemical synthetic substances. Although they can eliminate pollutants such as formaldehyde to a certain extent, they may also recreate other pollutants, resulting in secondary pollution. . Some inferior chemical smears form a simple closed coating film on the surface of the furniture. When the coating film ages and the weather is hot and ...
