Problems solved by technology

The existing technology for preparing new paper-based incense bases (patent numbers: 200610098567.2, 200710156089.0) is used for pilot production, but due to insufficient use of flame retardants and combustion enhancers, there is a large amount of smoke and dust when the incense bases are burned (refer to GB 24330 - 2009 relevant method test, the result is about 40mg / g, which belongs to the problems of smoke and mosquito coils), short ignition time, low drug volatilization rate, etc.

Embodiment 1

[0045] 46% waste paper pulp (containing 6.8% water by weight of waste paper pulp) is placed in a hydraulic pulper for disintegration, and then beaten by a disc refiner. The degree of beating is 40 ° SR, and 30 % carbon powder and 24% Al 2o 3 , after mixing evenly, use papermaking molding technology to make incense blanks. When the incense base is burned, the amount of smoke and dust is 22.5mg / g, and the burning time is 3min / cm.

Embodiment 2

[0047] 46% wood pulp (containing the moisture of 6.1% by weight of wood pulp) is placed in the hydraulic pulper to decompose, and then be beaten by a disc refiner. The degree of beating is 30 ° SR, and 30 % carbon powder and 24% Al 2 o 3 , after mixing evenly, use papermaking molding technology to make incense blanks. When the incense base is burned, the amount of smoke and dust is 19.5mg / g, and the burning time is 3.3min / cm.

Embodiment 3

[0049] 46% non-wood pulp (containing 7.6% moisture by weight of non-wood pulp) is placed in a hydraulic pulper to be dispelled, and then beaten by a disc refiner with a degree of beating of 50 ° SR. Add 30% carbon powder and 24% Al 2 o 3 , after mixing evenly, use papermaking molding technology to make incense blanks. When the incense body is burned, the amount of smoke and dust is 18mg / g, and the burning time is 3.5min / cm.

Abstract

The invention provides light mosquito-repellent incense blank with little smoke, comprising the following components by weight percent: 35-60% of paper pulp, 10-30% of carbon powder, 0-15% of calcium carbonate, 19-33% of silicoaluminate, 0-5% of sodium borate and 0-5% of potassium nitrate. The invention also provides a method for preparing the light mosquito-repellent incense blank. The light paper mosquito-repellent incense blank with little smoke is low in smoke amount, long in burning time, stable in burning, and unlikely to extinguish when being burned, also has the advantages of low breakage rate, light weight, convenient transportation and low cost, and can effectively replace the traditional black mosquito-repellent incense with little smoke.

Description

technical field [0001] The invention belongs to the field of daily chemical industry, and in particular relates to a mosquito-repellent incense blank and a preparation method thereof. Background technique [0002] Since the beginning of the 20th century, mosquito coils have experienced development stages such as smoked mosquito coils, small smoke mosquito coils, and smokeless mosquito coils, and have always occupied a leading position in my country's household hygiene and insecticide market. Traditional mosquito coils are made of carbon powder (charcoal powder or bamboo charcoal powder), wood powder (fir powder, wood powder, etc.) It is formed by spraying after stirring and blending, extruding, stamping and drying. [0003] At present, the mosquito-repellent incense of domestic household sanitation insecticide product mainly is made up of micro-smoke mosquito-repellent incense (accounting for 90%), smokeless mosquito-repellent incense. Among them, the micro-smoke mosquito-...
