A kind of folium artemisiae argyi fiber haveing excellent performance is obtained after handling under base silane short time specific temperature, can be improved the stretching of latex foam
Intensity, bacteriostasis property and permeability, and solve the problems, such as that existing latex foam is fragile.It may be due to Folium Artemisiae Argyi powder mesh number
The fiber of too small preparation is too long to easily lead to the rough influence latex cross-linking effect of sponge surface, and the fiber of the too big preparation of mesh number is easy group
Poly-, fiber is too short can not to play good humidification, and the fiber and rubber and calcium carbonate of mesh number Folium Artemisiae Argyi powder preparation
Effect is preferably, good to the abscess supporting role of formation, in addition containing chemical components such as volatile oil, flavonoids, triterpenes in folium artemisiae argyi
There is inhibiting effect to various pathogens, fungi and virus, is beneficial to the tensile property, bacteriostasis property and gas permeability of latex foam
Energy；Fiber is made of main components such as cellulose, pectin, organic matter, wood powders, and degumming tech also will affect the knot of tissue of fiber
Structure and function, traditional handicraft is due to using high-temperature process during the preparation process, and usually time is long, and the fibrous mechanical property of preparation is not
It is good, the natural structure of fiber is compromised, and easily lead to the loss of effective bacteriostatic ingredients, it is big because surface exists using rear folium artemisiae argyi fiber
Amount disperses poor compatibility through base, easy reunion and the nonpolar system of latex, and deteriorates bubble structure；Inventor has found to use
Sulfuric acid, gamma-ray irradiation, three step combination processing of sodium hydroxide, through the persulfuric acid preliminary degumming of low-temperature treatment energy in short-term, gamma-rays spoke
According to after processing colloid macromolecular in fiber can decompose, be conducive to the degumming effect for improving subsequent sodium hydroxide, when reducing degumming
Between, the damage to fiber is reduced, the content of hydroxyl and the loss of effective bacteriostatic ingredients in fiber are reduced；Further inventor's discovery
Using the processing for carrying out low temperature in short-term to fiber containing hydrosulphonyl silane, the generation silanol that silane hydrolyzate is formed is anti-with hydroxyl in cellulose
It answers, reduces hydroxy radical content, and silane improves the hydrophobicity of fiber, the sulfydryl energy and latex contained in fiber surface cladding
Cross-linking reaction improves the structural stability of dispersion compatibility and latex of the fiber in latex system, so that the abscess in system
It is uniform in size, while the oxidation illumination loss that can be avoided antipathogenic composition in fiber extends fungistatic effect.
Discovery is when using 11- mercapto-undecanoic oxygroup trimethyl silane, 2- mercaptoethyl triethoxy during the preparation process
When silane handles folium artemisiae argyi fiber together, the permeability for improving latex foam, tensile property can not only be improved, also there is certain journey
The improvement fungistatic effect of degree.Its may be due to, in system the alkyl chain of 11- mercapto-undecanoic oxygroup trimethyl silane compared with
It is long, the hydrophobicity of folium artemisiae argyi fiber can be preferably improved, improves that dispersion in system is compatible and foaming effect, but there is aperture
Gap is larger, and interconnected or generation is easy to cause between abscess to collapse instead, and 2- mercaptoethyl triethoxysilane is being added
Afterwards, it containing shorter alkyl chain and specific triethoxysilane, cooperates with and can make with 11- mercapto-undecanoic oxygroup trimethyl silane
Latex foam forms that preferable aperture is mesh-structured, improves the permeability of latex foam, and then improve tensile property, is conducive to
Inhibiting anaerobic bacteria that can preferably play antibacterial effect antipathogenic composition slow release and good permeability oxygen content more.It is preparing
It is had been surprisingly found that in the process when the mass ratio of 11- mercapto-undecanoic oxygroup trimethyl silane, 2- mercaptoethyl triethoxysilane is
(2-3): when 1, gained latex is had excellent performance, may be insufficient due to the very few effect of 2- mercaptoethyl triethoxysilane content, and
2- mercaptoethyl triethoxysilane content reacts that the cross-linked network to be formed is comparatively dense, and abscess is not easy to be formed when higher.
Calcium carbonate can preferably be dispersed in latex system by modified, enhance the mechanical property of latex system, but make
At latex foam rigidity too obdurability it is poor, a certain amount of folium artemisiae argyi fiber is being added, while enhancing and is having preferable
Toughening effect；And it is calcium carbonate modified after on surface introduce chain alkyl, the folium artemisiae argyi fiber phase interaction with the application preparation
Effect, silicon in the palmitamide propyl betaine alkyl chain and folium artemisiae argyi fiber on surface are steeped with preferable cause can be played in system
The alkyl chain of alkane can also cooperate with the foaming effect of increase system, and folium artemisiae argyi fiber plays a supporting role to abscess, assign abscess one
Fixed rigidity is improved to some extent to sponge mechanical property, resilience and gas permeability etc., and the latex foam of preparation has excellent
Different comprehensive performance.
