Embodiment 1

[0038] The mite and antibacterial agent is made by the following steps:

[0039] Step 1. Add 0.05mol spirodiclofen, 45.7mL isopropanol, 35mL water and 0.1g sodium hydroxide into a three-necked flask, raise the temperature to 55°C, stir and react for 1h, after the reaction is completed, filter, and extract the filtrate with ethyl acetate , removing ethyl acetate by distillation under reduced pressure to obtain intermediate 1;

[0040] Step 2. Add 0.04mol intermediate 1, 45.7mL dimethyl sulfoxide and 15mL cystine solution into the reaction kettle, add concentrated sulfuric acid dropwise at a speed of 100r / min, control the reaction temperature at 80°C, and stir for 2h , the reaction is finished, the reaction product is washed with deionized water, extracted with ethyl acetate, and the ethyl acetate is removed by distillation under reduced pressure to obtain intermediate 2, wherein the cystine solution is composed of cystine and 10% mass fraction of acetic acid solution according ...

Embodiment 2

[0047] The mite and antibacterial agent is made by the following steps:

[0048] Step 1. Add 0.05mol spirodiclofen, 48.2mL isopropanol, 36mL water and 0.2g sodium hydroxide into a three-necked flask, raise the temperature to 58°C, stir and react for 1.5h, after the reaction, filter, and the filtrate is washed with ethyl acetate Extraction, removal of ethyl acetate by distillation under reduced pressure, to obtain intermediate 1;

[0049] Step 2. Add 0.04mol intermediate 1, 46.7mL dimethyl sulfoxide and 18mL cystine solution into the reaction kettle, add concentrated sulfuric acid dropwise at a speed of 150r / min, control the reaction temperature at 86°C, and stir for 2.5 h, the reaction is finished, the reaction product is washed with deionized water, extracted with ethyl acetate, and the ethyl acetate is removed by distillation under reduced pressure to obtain intermediate 2, wherein the cystine solution is composed of cystine and 10% mass fraction of acetic acid solution acco...

Embodiment 3

[0056] The mite and antibacterial agent is made by the following steps:

[0057] Step 1. Add 0.05mol of spirodiclofen, 51.2mL of isopropanol, 38mL of water and 0.3g of sodium hydroxide into a three-necked flask, raise the temperature to 60°C, stir and react for 2 hours, after the reaction, filter, and extract the filtrate with ethyl acetate , removing ethyl acetate by distillation under reduced pressure to obtain intermediate 1;

[0058] Step 2. Add 0.04mol intermediate 1, 48.5mL dimethyl sulfoxide and 20mL cystine solution into the reaction kettle, add concentrated sulfuric acid dropwise at a speed of 200r / min, control the reaction temperature at 90°C, and stir for 3h , the reaction is finished, the reaction product is washed with deionized water, extracted with ethyl acetate, and the ethyl acetate is removed by distillation under reduced pressure to obtain intermediate 2, wherein the cystine solution is composed of cystine and 10% mass fraction of acetic acid solution accord...

Abstract

The invention relates to a bacteriostatic laundry fragrance-retaining bead, and belongs to the technical field of daily chemical detergents, wherein the bacteriostatic laundry fragrance-retaining bead comprises the following raw materials in parts by weight: 78.5-92.4 parts of polyethylene glycol, 0.7-1.2 parts of an acarus-killing antibacterial agent, 0.5-2 parts of toner, 1.5-2.8 parts of carbamide, 2-5 parts of alcohol, 4-10 parts of liquid essence, 4-10 parts of microcapsule essence, 2-5 parts of a nonionic surfactant, and 0.5-0.8 part of a washing assistant. The invention also discloses a preparation method of the fragrance-retaining bead, the liquid essence and the microcapsule essence endow the fragrance-retaining bead with fragrance-retaining performance, the washing assistant enhances the decontamination and cleaning performance of the fragrance-retaining bead, and the acarus-killing antibacterial agent molecule contains a spirodiclofen structure, a quaternary ammonium salt structure, a nitrogen-chloramine structure, an S-S bond of cystine, a -Si-O- chain, a hydrophobic benzene ring and a carbocyclic ring. The fragrance-retaining bead has the advantages that the fragrance-retaining bead has acarus-killing antibacterial effects and high wettability, can be tightly combined with clothes, and can play a lasting acarus-killing antibacterial effect.

Description

technical field [0001] The invention belongs to the technical field of daily chemical detergents, and in particular relates to antibacterial laundry fragrance beads and a preparation method thereof. Background technique [0002] Fragrance beads are clothes cleaning products. When washing clothes, add an appropriate amount of fragrance beads, and the fragrance will stay on the clothes for a long time after washing. The principle is that through friction, the smart microcapsules are exploded, releasing a pleasant fragrance, which lasts on clothes and resists odors such as hot pots and barbecues. [0003] Chinese patent CN110106030A discloses a fragrance-retaining bead, which comprises the following components: polyethylene glycol, silicon dioxide, essence, essence microcapsules, and dyes. Through the mutual cooperation of the components of the fragrance beads, it is conducive to the slow release of the essence and essence capsules during the washing process, which is conduciv...
