摘要
(CN105131230B) 本​发明​公开​了​种​除臭​型​长效​缓释​植物​精油​聚氨酯​软​质​泡沫​的​制备​方法,首先​将​埃洛​石​纳米​管​活化,然后​在​活化​后的​埃洛​石​纳米​管​表面​通过​环​糊精​和​异​氰酸​酯​的​聚合反应​形成​网状结构,再通过​浸渍​将​精油​装载​入​纳米​管内。然后​将​固体​植物​精油​添加​到​聚氨酯​泡沫​的​聚合反应​过程中,利用​固体​植物​精油​表面的​环​糊精​分子​上​的​活性​基团​可以​参与​聚氨酯​泡沫​的​聚合反应,从而​使得​固体​植物​精油​和​聚氨酯​软​质​泡沫​之间​紧密​相连,不容易​脱落。

主权利要求
(CN105131230B) 1. Long-acting sustained-release plant essential oil deodorant type flexible polyurethane foam is a method of preparing, characterized in: preparing method comprises the following steps: Will (1) be at a temperature of nanotubes halioysite 25-80 Ć, immersed in dilute hydrochloric acid 5-20% of mass fraction of from 30-60 minutes, in order filtering, washing, drying, is activated halioysite nanotubes; In (2) an inert gas atmosphere, in accordance with the cyclodextrin to solvent weight ratio is 1:5-1:10 the cyclodextrin dissolved in a solvent, to obtain cyclodextrin solution, the solvent is dimethyl sulfoxide or N, N-dimethylformamide; recharged to the cyclodextrin solution was added to give the (1) activation of halloysite nanotube, a nanotube and a weight ratio of 1:3 activation halioysite cyclodextrin-1:10, a resulting solution was mixed well; a isocyanate was added to the solution again, 1:1 weight ratio of cyclodextrin with an isocyanate-1:5, mixed to homogeneity resulting solution b; b heat the solution to a temperature of 40-100 Ć to a polymerization reaction, the reaction was completed was washed, dried, milled to give halioysite-cyclodextrin polymer composite material; The (3) step (2) resulting halioysite-cyclodextrin polymer composite material is added to the native plant essential oils, in accordance with halioysite-cyclodextrin polymer composite material and natural plant essential oil weight ratio 1:2-1:5, vacuum impregnation 5-24 hours, and then washed, dried to a solid plant essential oil; To give the (3) solid plant essential oil is added to the (4) kettle butter PPG, with a high speed mixer and mixing for 20-70 minutes, until the solid plant essential oil and butter PPG mix well; wherein each batch in parts by weight ratio of: Solid plant essential oil 8-12 parts; Butter PPG 15-40 parts; Continue (5) the reaction kettle were added sequentially to the butter PPG 1.0-3.5 parts by weight of water, 2.0-5.5 parts by weight of a cell opener, 1.0-2.0 parts by weight of liquid ammonia, 35-80 parts by weight of silicone oil and 0.25-0.5 parts by weight of catalyst, with a high speed mixer and mixing for 15-60 hs; in the vessel was continuously added 50-100 parts by weight of MDI, with a high speed mixer and mixing for 15-60 hs, and then directly into a polyurethane reaction tank; After 2 hours of aging at (6) room temperature environment placed naturally, polyurethane flexible foam obtained plant essential oil. 6. Claim 1 obtained by the method using the deodorant type prolonged-release plant essential oil polyurethane flexible foam.
