example 1

[0015] Mix 5 g of methyl methacrylate, 5 g of n-butyl methyl acrylate, 1 g of camphor essential oil, 0.1 g of hexadecane, and 0.1 g of azobisisobutyronitrile, and gradually drop them into 88.8 g of olefin-containing In an aqueous solution of 1 g of sodium propoxy hydroxypropyl sulfonate, emulsify at high speed, and place it under an ultrasonic cell pulverizer for 10 minutes to obtain an O / W fine emulsion. Transfer the O / W mini-emulsion to a four-necked flask equipped with a condensing reflux and stirring device. After passing nitrogen for 30 minutes, at a stirring speed of 600 rpm, raise the temperature to 60°C and react for 3.5 hours. filter membrane to prepare camphor essential oil / latex particles. Performance test found: O / W miniemulsion particle size d 1 =127.1nm, camphor essential oil / latex particle size d 2 =134nm, after being applied to the fabric, the retention rate of camphor essential oil at room temperature for 7 days is 95.33%.

example 2

[0017] Mix 20g of styrene, 30g of n-butyl methyl methacrylate, 5g of camphor essential oil, 2g of cetyl alcohol, and 2.5g of benzoyl peroxide, and gradually drop to 40.5g of methacrylate containing methacrylate under the action of mechanical stirring. In an aqueous solution of 5 g of bis-quaternary ammonium salt and 10 g of methacrylate-based quaternary ammonium salt, after high-speed emulsification, it was placed in a sand mill for 120 minutes to obtain an O / W fine emulsion. Transfer the O / W miniemulsion to a four-necked flask equipped with a condensing reflux and stirring device. After 5 minutes of nitrogen gas flow, the temperature was raised to 80°C at a stirring speed of 250 rpm, and the reaction was carried out for 5 hours. filter membrane to prepare camphor essential oil / latex particles. Performance test found: O / W miniemulsion particle size d 1 =144.9nm, camphor essential oil / latex particle size d 2 =119.6nm, after being applied to the fabric, the retention rate of c...

example 3

[0019] Mix 20g of isoprene, 1g of camphor essential oil, 0.4g of dodecyl mercaptan, and 0.5g of tert-butyl peroxybenzoate, and gradually drop into 78.1g of After high-speed emulsification in an aqueous solution of 1 g of sodium, place it in a sand mill for 60 minutes to obtain an O / W fine emulsion. Transfer the O / W miniemulsion to a four-neck flask equipped with a condensing reflux and stirring device. After passing nitrogen for 15 minutes, at a stirring speed of 400 rpm, raise the temperature to 80°C and react for 2.5 hours. filter membrane to prepare camphor essential oil / latex particles. Performance test found: O / W miniemulsion particle size d 1 =164.5nm nm, camphor essential oil / latex particle size d 2 =240.7nm, after being applied to the fabric, the retention rate of camphor essential oil at room temperature for 7 days is 96.28%.

Abstract

The invention provides a preparation method of a functional finishing agent cinnamomum camphora essential oil / emulsion particle for a textile, and belongs to the field of fine chemicals and material science. The preparation method comprises the following steps of mixing a monomer, cinnamomum camphora essential oil, an emulgator, a coemulsifier and an initiator in a certain proportion; performing fine emulsification; and then heating and polymerizing to prepare the cinnamomum camphora essential oil / emulsion particle with high stability and having particle of 50 to 300nm. According to the preparation method, the surface of the cinnamomum camphora essential oil is covered with the emulsion particle, so that the defect that the cinnamomum camphora essential oil is volatile can be overcome, and the cinnamomum camphora essential oil can be released slowly after taking. By adopting the preparation method, natural resources can be recycled, and the duration of action of the cinnamomum camphora essential oil on the surface of the textile can be prolonged. The preparation method has the characteristics of environment friendliness, low irritation, etc.

Description

technical field [0001] The invention belongs to the technical fields of fine chemical industry and material science, and in particular relates to a preparation method of camphor essential oil / latex particles, a functional finishing agent for textiles. technical background [0002] Camphor essential oil is a biologically active oily substance isolated and extracted from camphor roots, wood, branches and leaves. Anthelmintic, laxative, skin warming, motivating, sweating, anthelmintic, wound healing, etc. At present, camphor essential oil has been widely used in all walks of life. In terms of medicine, camphor essential oil has medical and health care effects on skin, nervous system and mental health on the one hand, and on the other hand has the effect of treating colds and reducing inflammation. Pain relief and antipruritic effects; in the food industry, certain substances in camphor essential oil can be used as natural food additives, such as natural pigments, spices, swee...
