Embodiment 1

[0024] An environmentally friendly mosquito-repellent incense adhesive, the preparation steps are as follows:

[0025] S1: tapioca starch slurry A with a concentration of 15Be';

[0026] S2: Add ethyl acetate and acrylamide with a concentration of 0.5% to the cassava starch slurry A in step S1, and then carry out cross-linking and grafting reaction at a temperature of 28°C and a stirring speed of 50r / min for 1h to prepare slurry B ;

[0027] S3: transporting the slurry B in step S2 to a drum dryer for pregelatinization and drying at a temperature of 150° C. to obtain a material C with a water content of 8%;

[0028] S4: The material C in step S3 is pulverized, passed through a 60-mesh sieve, and sent to a cyclone separator for collection by wind to obtain an environmentally friendly mosquito-repellent incense adhesive.

Embodiment 2

[0030] An environmentally friendly mosquito-repellent incense adhesive, the preparation steps are as follows:

[0031] S1: Tapioca starch slurry A with a concentration of 20Be';

[0032] S2: Add ethyl acetate and acrylamide with a concentration of 0.8% to the tapioca starch slurry A in step S1, and then carry out cross-linking and grafting reaction at a temperature of 35°C and a stirring speed of 80r / min for 0.5h to prepare a slurry B;

[0033] S3: transporting the slurry B in step S2 to a drum dryer for pregelatinization and drying at a temperature of 160° C. to obtain a material C with a water content of 6%;

[0034] S4: The material C in step S3 is pulverized, passed through a 60-mesh sieve, and sent to a cyclone separator for collection by wind to obtain an environmentally friendly mosquito-repellent incense adhesive.

Embodiment 3

[0036] An environmentally friendly mosquito-repellent incense adhesive, the preparation steps are as follows:

[0037] S1: Tapioca starch slurry A with a concentration of 18Be';

[0038] S2: Add ethyl acetate and acrylamide with a concentration of 0.8% to the tapioca starch slurry A in step S1, and then carry out cross-linking and grafting reaction at a temperature of 30°C and a stirring speed of 70r / min for 0.75h to prepare a slurry B;

[0039] S3: Transport the slurry B in step S2 to a drum dryer for pregelatinization and drying at a temperature of 155° C. to obtain a material C with a water content of 7%;

[0040] S4: The material C in step S3 is pulverized, passed through a 60-mesh sieve, and sent to a cyclone separator for collection by wind to obtain an environmentally friendly mosquito-repellent incense adhesive.

Abstract

The invention discloses an environment-friendly mosquito-repellent incense adhesive and belongs to the technical field of mosquito-repellent incense additive preparation.Cassava starch is used as the raw material, crosslinking graft reaction with ethyl acetate and acrylamide is conducted, then pregelatinization reaction is conducted, and finally drying, smashing and screening are conducted to obtain the adhesive.The prepared environment-friendly mosquito-repellent incense adhesive is high in dissolving property, viscosity and binding force, and the use amount of mosquito-repellent incense produced from the environment-friendly mosquito-repellent incense adhesive is small.The prepared environment-friendly mosquito-repellent incense adhesive is free of toxicity or harm, can meet the requirement for environment friendliness, and can not cause negative effects such as asthma, neurotoxia and cancer after being burnt and absorbed by people.

Description

【Technical field】 [0001] The invention belongs to the technical field of preparation of mosquito-repellent incense additives, and in particular relates to an environmental-friendly mosquito-repellent incense adhesive. 【Background technique】 [0002] Existing mosquito-repellent incense adhesive mainly adopts synthetic adhesive such as carboxymethyl cellulose, polyacrylamide etc. A large number of synthetic adhesives are used in mosquito coils, which brings a lot of environmental protection and health problems. These chemical substances may cause asthma, neurotoxicity, long-term inhalation and even cancer if absorbed by the human body after burning. Therefore, how to develop an environmentally friendly mosquito-repellent incense adhesive has become a new research direction. 【Content of invention】 [0003] The invention provides an environmentally friendly mosquito-repellent incense adhesive to solve the problems of environmental protection and health caused by the large amo...
