[0036] In an embodiment, the preparation method of the novel smokeless mosquito-repellent incense comprises the following steps:

[0037] 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;

[0038] S2: Take 140-160 parts of sludge carbon powder prepared in step S1, 6-8 parts of anthracite, 24-30 parts of binder, 4-6 parts of mica powder, and 400-480 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;

[0039] 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;

[0040] S4: Spray the mosquito-repellent incense potion evenly on the surface of...

Embodiment 1

[0049] A preparation method of a novel smokeless mosquito-repellent incense, comprising the following steps:

[0050] 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;

[0051] S2: Take 140 parts of sludge carbon powder, 6 parts of anthracite, 24 parts of binder, 4 parts of mica powder, and 400 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;

[0052] 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;

[0053] S4: Spray the mosquito-repellent incense potion evenly on the surface of the dried mosquito-repellent coil prepared in step S3 a...

Embodiment 2

[0061] A preparation method of a novel smokeless mosquito-repellent incense, comprising the following steps:

[0062] 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;

[0063] S2: Take 160 parts of sludge carbon powder, 8 parts of anthracite, 30 parts of binder, 6 parts of mica powder, and 480 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;

[0064] 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;

[0065] S4: Spray the mosquito-repellent incense potion evenly on the surface of the dried mosquito-repellent coil prepared in...

Abstract

The invention discloses a preparation method of novel smokeless mosquito-repellent incense, belonging to the technical field of preparation of the mosquito-repellent incense. The novel smokeless mosquito-repellent incense is prepared by the steps of preparing sludge carbon powder, preparing paste, molding the paste, drying the molded paste, spraying chemicals onto a dry mosquito-repellent incense blank, and the like. According to the preparation method, sludge carbon is taken as an incendiary agent, and an inorganic substance in the sludge carbon is taken as a flame retardant, so that not only is a new way provided for the resource utilization of the sludge carbon, but mass disafforestation caused by the mosquito-repellent incense industry is also avoided, and the preparation method of the novel smokeless mosquito-repellent incense is beneficial to environmental protection. The novel smokeless mosquito-repellent incense is non-toxic and harmless and can meet the requirement of environmental protection for the product; after the novel smokeless mosquito-repellent incense is burnt and absorbed by the human body, asthma, nerve poisoning and cancers are not caused; the novel smokeless mosquito-repellent incense has a smooth appearance, is free from fracture and mildew spots, and has the breaking-resistant strength of 425-456g and the ignition point time of 8.61-9.01h; in the burning process, smoke is not generated; the novel smokeless mosquito-repellent incense avoids a phenomenon of broken-end flameout when being burnt to an iron-tooth disk.

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 a novel smokeless 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 th...
