Embodiment 1

[0029] Weigh 1g of montmorillonite into a 250ml three-necked flask, add 100ml of deionized water, adjust the pH to 4.0, and then add 0.1g of cationization reagent glycidyltrimethylammonium chloride to the montmorillonite suspension solution, the reaction was stirred at 20°C for 1 h, and then the filtered product was vacuum-dried at 50°C to constant weight. The vacuum-dried product was added to an organic solvent of a silane coupling agent, the silane coupling agent being 0.1 g of 3-aminopropyltrihexyloxysilane, and the organic solvent being 50 ml of methanol. React at a temperature of 80°C for 12 hours, filter the product and wash three times with methanol and acetone, and dry the washed product in vacuum at 50°C for 10 hours to obtain glycidyltrimethylammonium chloride cationized and Silane coupling agent alkylated montmorillonite.

Abstract

The invention discloses a porous inorganic material with insecticidal and mothproof functions and a preparation method thereof. The porous inorganic material with insecticidal and mothproof functions takes porous inorganic material as a carrier, the outer surface of the carrier is grafted with cationization reagent, the inner surface of the duct of the porous inorganic material is grafted with silane coupling agent, and micromolecule mothproof drug is loaded in a pore. The preparation method for the porous inorganic material with insecticidal and mothproof functions comprises the following steps: carrying out covalent modification on the porous inorganic material; grafting a functional group with a cation electric charge on the surface of the porous inorganic material; and loading the micromolecule insecticide into the pore of the porous inorganic material. The porous inorganic material with insecticidal and mothproof functions, which is prepared by using the preparation method disclosed by the invention, has the advantages of excellent insecticidal and mothproof functions, low cost, simple preparation technology and good commercial application prospect and can be used for fields,such as buildings, papermaking, coating, hygiene products and the like.

Description

technical field [0001] The invention relates to a porous inorganic material and a preparation method thereof, in particular to a porous inorganic material with insecticidal and insect-proof functions and a preparation method thereof. Background technique [0002] Insecticides, as widely used chemicals, have been widely valued due to their own toxicity and their impact on the ecological environment. It takes a lot of research funds and research time to develop a low-toxicity and high-efficiency new insect repellent, and through the improvement of dosage form processing technology, not only can improve the efficacy, save dosage, but also reduce residue and pollution, reduce toxicity, and insect repellent It is an important method to make medicine into controlled (sustained) release agent. [0003] At present, the research on drug controlled and sustained release mainly focuses on the study of human medicine, but there are few studies on the sustained release of insecticidal a...
