(3) by 1,8- diacetyls -3- carboxyls anthraquinone and anhydrous dimethyl formamide with solid-to-liquid ratio 1：(8-10)(g/mL) Mixing adds in the Glucosamine hydrochlorate of 1-1.2 times of 1,8- diacetyl -3- carboxyl anthraquinones quality and 1,8- diacetyl -3- The dicyclohexylcarbodiimide of 0.5-0.6 times of carboxyl anthraquinone quality is stirred to react in 23-25 DEG C with 200-300 revs/min When 20-24 is small；After reaction, reaction solution is collected into filtrate using 80-100 mesh filter-cloth filterings；Anhydrous two are added in into filtrate The glacial acetic acid of 0.05-0.06 times of methylformamide volume mixes and stands 30-40 minutes after 0-2 DEG C, using 80-100 mesh filter clothes Filtrate is collected in filtering；The water of 0.5-0.8 times of filtrate volume is added in into filtrate, when 20-25 DEG C of standing 5-10 is small, using 80- 100 mesh filter-cloth filterings collect filter cake；Filter cake is chromatographed using silicagel column, mobile phase is by ethyl acetate and hexamethylene with body Product is than (0.7-0.8)：1 mixes, and collects eluent；By eluent in 50-60 DEG C, the condition of vacuum degree 0.07-0.09MPa When lower dry 6-10 is small, the Aloe emodin derivative II is obtained.
Inventor has found in practice process, is grafted the anti-microbial property of the polypropylene non-woven fabric of Aloe emodin derivative II Better than grafting aloe-emodin or the polypropylene non-woven fabric of Aloe emodin derivative I.This may be due to aloe-emodin Hydroxyl on derivative II on Han You Onion Huan , Onion rings has certain contribution function for antibacterial effect.
Among the prior art, usually the mechanical property of coating and wear-resisting property etc. are improved by adding inorganic particulate.But Be inorganic particulate additive amount it is more, be more unfavorable for the adhesiving effect of coating.This invention address that it provides a kind of with good viscous The coating of attached effect and very good mechanical properties.
In the present invention, it is in the process of nonwoven surface prepares coating：
(1) formulation for coating material：Functional particles 17-20%, organic bond 20-30wt%, mass fraction are 5% six inclined phosphorus Acid sodium aqueous solution 1-2wt%, surplus are dimethylformamide；
(2) dimethylformamide of dimethylformamide total amount 60-70% is weighed, functional particles are added in, with 400-500 Rev/min rotating speed stir 20-30 minute, add in mass fraction be 5% sodium hexametaphosphate solution, continue with 400-500 Rev/min rotating speed stir 30-40 minutes, obtain mixed liquor I；
(3) organic bond with remaining dimethylformamide is mixed, 10- is stirred with 400-500 revs/min of rotating speed After twenty minutes, 30-40 minutes are stood in 20-25 DEG C, obtains mixed liquor II；
(4) mixed liquor I that step (2) obtains is added in the mixed liquor II that step (3) obtains, with 400-500 revs/min The rotating speed of clock stirs 20-30 minutes, obtains coating；
(5) by coating by way of padding coated in nonwoven surface, the solid-to-liquid ratio of non-woven fabrics and coating is 1：(20- 30) (g/mL) is dried 3-5 minutes in 90-100 DEG C；Non-woven fabrics is subjected to secondary coating, non-woven fabrics and painting by way of padding The solid-to-liquid ratio of material is 1：(20-30) (g/mL) is dried 3-5 minutes in 90-100 DEG C；By non-woven fabrics non-woven weight 50-200 Times deionized water washing, when dry 8-12 is small under conditions of 50-60 DEG C, vacuum degree 0.07-0.08MPa to get.
The polyethers that the functional particles are montmorillonite-dimethyl silicone polymer functional particles, silica-DOPA is amine-modified One kind or its composition in sulfone functional particles.Preferably, the functional particles are montmorillonite-dimethyl silicone polymer function grain The mixture of son and the amine-modified polyether sulfone functional particles of silica-DOPA, wherein montmorillonite-dimethyl silicone polymer function The mass ratio of particle and the amine-modified polyether sulfone functional particles of silica-DOPA is 1：(2-3).
The preparation process of the montmorillonite-dimethyl silicone polymer functional particles is：By absolute ethyl alcohol, deionized water, 3- Aminopropyltriethoxywerene werene is with weight ratio (15-20)：1：1 is uniformly mixed, and obtains mixed liquor；By mixeding liquid volume 0.01- 0.02 times of dimethyl silicone polymer is added in mixed liquor, is handled under conditions of 45-50 DEG C, ultrasonic power 300-400W 30-50 minutes, obtain sonification fluid；The illiteracy that 0.5-0.7 times of dimethyl silicone polymer weight is added in into sonification fluid takes off Soil, in the rotating speed of 45-50 DEG C, 210-300 revs/min be stirred to react 12-15 it is small when；After the completion of reaction, reaction solution is used into 80- 100 mesh filter-cloth filterings collect filter cake；After filter cake is washed with the deionized water of 50-100 times of filter cake weight, in 50-60 DEG C, it is true When drying 6-10 is small under conditions of reciprocal of duty cycle 0.07-0.09MPa, the montmorillonite-dimethyl silicone polymer functional particles are obtained.
For dopamine after polyether sulfone surface aggregate, the poly-dopamine of generation can freely be coated on the table of arbitrary solid matter Face, and non-covalent bond effect power is generated, enhance the combination power between dopamine and substance, while substantial amounts of reactivity is provided Position.Under the catalytic action of ammonium hydroxide, the silanol for being dehydrated generation can occur to take off tetraethyl orthosilicate with the hydroxyl on dopamine surface Water reacts, so as to achieve the purpose that growth in situ nano silicon dioxide.This not only contributes to adherency of the functional particles in base fabric, Being cross-linked with each other between particle is also beneficial to, enhances the interface cohesion effect between polymer.
The preparation process of the amine-modified polyether sulfone functional particles of the silica-DOPA is：Using trihydroxy methyl amino The PH of deionized water is adjusted to 8.5 by methane；By dopamine and the deionized water of pH is mixed up with solid-to-liquid ratio 1：(400-500)(g/ ML) it is uniformly mixed, adds in the polyether sulfone of 50-60 times of dopamine weight, 20-24 is stirred to react with 200-300 revs/min of rotating speed Hour；By reaction solution using 80-100 mesh filter-cloth filterings, filter cake is collected；By filter cake in 70-80 DEG C, vacuum degree 0.06-0.08MPa Under conditions of dry 8-10 it is small when, obtain the amine-modified polyether sulfone of DOPA；By the amine-modified polyether sulfone of DOPA and absolute ethyl alcohol with Solid-to-liquid ratio 1：(8-12) (g/mL) is uniformly mixed, and is ultrasonically treated 20-30 minutes under conditions of ultrasonic power 300-400W, by nothing The ammonium hydroxide that the concentration of 0.01-0.02 times of water-ethanol volume is 25-28% adds in, and is uniformly mixed and obtains mixed liquor A；By ammonium hydroxide volume 0.9-1 times of tetraethyl orthosilicate and the absolute ethyl alcohol of 20-30 times of ammonium hydroxide volume are uniformly mixed, and obtain mixed liquid B；By mixed liquor B is added in mixed liquor A, with 200-300 revs/min of rotating speed be stirred to react 20-25 it is small when；By reaction solution in 50-55 DEG C, it is true When drying 10-16 is small under conditions of reciprocal of duty cycle 0.06-0.08MPa, the amine-modified polyether sulfone function of the silica-DOPA is obtained Particle.
Protective garment of the present invention have the characteristics that ventilative, anti-asbestos penetrate, waterproof, antibacterial it is wear-resisting, be mainly used in doctor The environment such as institute, farm, Center for Disease Control, oil drilling, toilet workshop.
