[0031] In an embodiment, the preparation method of novel mosquito-repellent incense comprises the following steps:

[0032] S1: After the sludge is dried at 106-110°C for 20-23h, under the protection of nitrogen or carbon dioxide, the temperature is raised to 500-600°C at a rate of 20-25°C / min, carbonized for 0.6-1h, and cooled to obtain Sludge carbon, after the sludge carbon is crushed through a 60-80 mesh sieve, sludge carbon powder is obtained;

[0033] S2: Take 120-200 parts of sludge carbon powder prepared in step S1, 5-8 parts of anthracite, 20-32 parts of binder, 4-6 parts of mica powder, and 380-500 parts of water, at a temperature of 60-70 °C, stirring at a speed of 200-300r / min for 1-2h to obtain a paste;

[0034] S3: Put the paste prepared in step S2 into a mold, compact and demould, and then dry at 45-55°C until the water content is ≤10%, to obtain a dry mosquito coil;

[0035] S4: Spray the mosquito-repellent incense medicine evenly on the surface of the dried m...

Embodiment 1

[0044] A preparation method for novel mosquito-repellent incense, comprising the following steps:

[0045] S1: After drying the sludge at 106°C for 23 hours, under the protection of nitrogen, raise the temperature to 500°C at a heating rate of 20°C / min, carbonize for 1 hour, obtain sludge carbon after cooling, and pulverize the sludge carbon Sludge carbon powder is obtained after passing through a 60-mesh sieve;

[0046] S2: Take 120 parts of sludge carbon powder, 5 parts of anthracite, 20 parts of binder, 4 parts of mica powder, and 380 parts of water prepared in step S1, and stir for 2 hours at a temperature of 60 °C and a speed of 200 r / min to prepare get a paste;

[0047] S3: Put the paste prepared in step S2 into a mold, compact and demould, and then dry at 45°C until the water content is 10%, to obtain a dry mosquito coil;

Embodiment 2

[0056] A preparation method for novel mosquito-repellent incense, comprising the following steps:

[0057] S1: After the sludge was dried at 110°C for 20 hours, under the protection of nitrogen or carbon dioxide, the temperature was raised to 600°C at a heating rate of 25°C / min, carbonized for 0.6h, and sludge carbon was obtained after cooling. Carbon pulverized through 80 mesh sieve to obtain sludge carbon powder;

[0058] S2: Take 200 parts of sludge carbon powder, 8 parts of anthracite, 32 parts of binder, 6 parts of mica powder, and 500 parts of water prepared in step S1, and stir for 1 hour at a temperature of 70 °C and a speed of 300 r / min to prepare get a paste;

[0059] S3: Put the paste prepared in step S2 into a mold, compact and demould, and then dry at 55°C until the moisture content is 8%, so as to obtain a dry mosquito coil;

[0060] S4: Spray the mosquito-repellent incense potion evenly on the surface of the dried mosquito-repellent coil prepared in step S3 an...

Abstract

The invention discloses novel mosquito-repellent incense and belongs to the technical field of preparation of the mosquito-repellent incense. The novel mosquito-repellent incense is prepared from the following raw materials in parts by weight: 120 to 200 parts of sludge carbon powder, 5 to 8 parts of anthracite coal, 20 to 32 parts of an adhesive, 4 to 6 parts of mica powder and 380 to 500 parts of water. According to the novel mosquito-repellent incense takes the sludge carbon as a combustion agent and inorganic matters in the sludge carbon as a fire retardant, so that a new way is provided for recycling utilization of the sludge carbon; meanwhile, a lot of forests are prevented from being cut down by a mosquito-repellent incense industry so that environment protection is facilitated; the novel mosquito-repellent incense disclosed by the invention is toxin-free and harmless and can meet the requirement on the product in the environment-friendly aspect; the novel mosquito-repellent incense does not cause asthma, neurotoxicity and cancers when the novel mosquito-repellent incense is absorbed by human bodies after combustion. The novel mosquito-repellent incense has a flat appearance and no cracks, the anti-fracture force reaches 426g to 459g and the ignition time reaches 8.85h to 9.24h; no smoke is generated in a combustion process and the novel mosquito-repellent incense is not broken and flamed out when passing through an iron-tooth disc.

Description

technical field [0001] The invention belongs to the technical field of mosquito-repellent incense preparation, and in particular relates to a preparation method of novel mosquito-repellent incense. Background technique [0002] Municipal sludge is the solid matter separated during the treatment of domestic sewage. These solid substances may already exist in sewage, such as suspended substances intercepted in various natural sedimentation tanks; they may also be transformed during sewage treatment, such as biological treatment and chemical treatment, from the original dissolved substances and colloids Biological flocs and suspended matter derived from material transformation. But generally speaking, the sludge of urban sewage treatment plants belongs to organic sludge, which is characterized by high organic matter content (60%-80%), fine particles (0.02-0.2mm), and low density (1.002-1.006g / cm 3 ), into a colloidal structure, accounting for about 0.3%-0.5% of the total trea...
