Abstract

The invention relates to a konjac glucomannan mite killing patch and a preparation method thereof. The preparation method comprises following steps: preparing a konjac glucomannan adhesive solution; filtering; preparing a konjac glucomannan / chitosan nano fibrous membrane; and preparing the mite killing patch. The konjac glucomannan / chitosan nano fibrous membrane is taken as the carrier of the konjac glucomannan mite killing patch; a mite attractant and other auxiliary agents are added; and mites in bedclothes and sofas can be effectively eliminated. The mite killing patch has an excellent adhesive performance, kills mites in a physical mode, and is harmless for human body. Konjac glucomannan is used as the main material of the mite killing patch; compared with a plastic plate, konjac glucomannan has a better drug carrying performance and stronger mite killing performance, and the mite killing patch can keep the cleanness and hygiene of bedclothes for a long term. The konjac glucomannanmite killing patch can be completely and biologically decomposed, is environmentally friendly and low-carbon, moreover, the raw materials are easily available, the price is cheap, and the productiontechnology is simple.

Description

technical field [0001] The invention relates to an insect-removing sheet and a preparation method thereof, in particular to a konjac glucomannan anti-mite sheet and a preparation method thereof. Background technique [0002] Mites belong to a class of tiny animals of Arthropoda Arachnida, with mouthparts at the front end and diverse feeding habits. At present, there are more than 50,000 species of mites found in the world, second only to insects. Mites are very closely related to human health, such as leather mites, chiggers, scabies, dust mites, and cat mites, which can bite people and suck blood, infect the skin, and cause "rosacea" or demodicosis, allergies, and urinary tract mites , pulmonary acariasis, intestinal acariasis and scabies, which seriously endanger human health. The invasion of mites into the skin can cause local foreign body reactions, leading to local inflammatory lesions, such as hair fat organ blockage, stimulation of horny layer hyperplasia, hair foll...
