Description

A kind of antibacterial, anti-mite, except aldehyde bamboo mat manufacturing method
(1) technical field
The present invention relates to a kind of manufacturing methods antibacterial, anti-mite, except aldehyde bamboo mat.
(2) background technique
Bamboo mat is China's temperature, essential product on tropical summer bed.The surface layer of bamboo mat is establishment bamboo silk curtain, is rich in nutrition Substance, such as starch (2%~6%), protein (1.5%~6%), carbohydrate 2% and fat and wax (2%~4%), suitable Under the conditions of suitable temperature and humidity, it is easy to mildew occur and damage by worms.In addition, bamboo mat is inconvenient to wash, as bedding, if Lack sunning (need to be exposed to the sun) environment or habit, the gap of bamboo mat and concave-convex surface position are easy to breed mite in use Worm can lead to the hidden danger such as skin allergy, be detrimental to health.
Currently, the most common bamboo mat is increased by bamboo curtain splint, gauze and back side reinforcement material up of three-layer, gauze and the back side on the market Strong material is carried out glued by adhesive and bamboo curtain splint.The bamboo mat of enterprise's production at present uses urea-formaldehyde resin adhesive, glued to increase Intensity, formaldehyde applied amount is more, causes bamboo mat burst size of methanal (content) exceeded.The burst size of methanal World Health Organization (WHO) International cancer research institution (IARC) be determined as carcinogenic substance.With human body intimate contact in bamboo mat use process, formaldehyde will Directly it is detrimental to health.Mainly take the development of modification to Lauxite, Novel adhesive at present, and to press-paste technique and Subsequent processing etc. improves, but has also been proposed new problem simultaneously, i.e., when burst size of methanal is reduced, back side reinforcing material Gluing between bamboo curtain splint is undesirable, is easy to happen degumming layering.In addition, the back side reinforcement material of bamboo mat, i.e., so-called " rattan Grass " be really regenerated celulose fibre, have in process addition the possibility containing aldehyde adhesive, be bamboo mat formaldehyde another come Source.
(3) summary of the invention
The present invention provides a kind of system antibacterial, anti-mite, except aldehyde bamboo mat for technical problem existing for existing bamboo mat product Method is made, using the water extract of the natural biomass materials such as bamboo leaf, peanut shell, pomelo peel and orange peel as reducing agent and protection Agent carries out reduction reaction to silver nitrate weak solution, forms Silver Nanoparticles homogeneous solution, passes through bamboo silk dipping or bamboo mat surface layer The techniques such as brushing load on bamboo mat, play antibacterial, anti-mite effect.At the bamboo mat back side, activity is wrapped up in the inside of cellulose fibre Charcoal captures the formaldehyde of the release in bamboo mat glue-line and auxiliary material in time.
The technical solution adopted by the present invention is that:
A kind of antibacterial, anti-mite, except aldehyde bamboo mat manufacturing method, which comprises
(1) fresh plant material is selected, cleans up, dry, 10~30min of boiling in boiling water is added or adds distilled water Juicing, filtering, takes filtrate constant volume, obtains natural extracting solution A, and (i.e. 10~50g plant is former for plant material raw drug content in extracting solution Material, final to obtain 1L extracting solution) it is 10~50g/L；The plant material be it is one of following, but not limited to this: bamboo leaf, peanut Shell, pomelo peel and orange peel；
(2) the addition extracting solution A in the silver nitrate solution B of 0.02~2mol/L of concentration, adjusting pH value to 7~12, then plus Enter suitable distilled water, stir evenly, obtains nano silver reaction liquid C, the silver ion final concentration of 0.8 in nano silver reaction liquid C ~1.5mmol/L, the extracting solution A volume of addition account for the 0.4%~20% of nano silver reaction liquid C volume；It is anti-under normal temperature conditions It answers 8~for 24 hours or is heated to 70~100 DEG C of 15~60min of reaction, obtain dark Nano silver solution D；
(3) at normal temperatures and pressures, will prepare the raw material bamboo silk of bamboo mat in Nano silver solution D after 2~6h of thorough impregnation again Finished product bamboo mat is made, or sprays or brush Nano silver solution D on finished product bamboo mat surface, dries under room temperature or cryogenic conditions to aqueous Rate is 7~11% (w/w)；
(4) bamboo mat back side cellulose fiber surface first applies one layer of tung oil, then evenly dispersed active carbon powder, then wraps up again Cotton thread or folding, finally carry out compress, cutting edge, bound edge, obtain it is described it is antibacterial, anti-mite, remove aldehyde bamboo mat finished product.
Silver is one kind most widely used in inorganic bacteriostatic agent, can reach elimination by haptoreaction and light-catalyzed reaction The effect of bacterium, has hundreds of bacteriums and acarid class lethal, and especially in the environment of warm moist, silver ion has Very high activity is 120 times of general nano material bactericidal potency.Had using nano silver antibacterial agent made from plant extraction liquid There are strong and broad-spectrum antibacterial, hypotoxicity, fast light hot, long-term effect, easily disperse, and the characteristics of bacterium will not develop drug resistance.
Bamboo mat back side reinforcing material generally uses regenerated celulose fibre package cotton thread in a strip shape or directly folds in a strip shape Woven again to form, the present invention first applies one layer of tung oil, then evenly dispersed active carbon powder on regenerated cellulose surface, then wraps again Wrap up in folding.Active carbon can be breathed freely in inside, the formaldehyde of the glue-line release between regenerated celulose fibre and its bamboo curtain splint It is captured, has preferable effect to removal Form aldehyde release.
The plant material is preferably bamboo leaf.
Concentration of silver ions is 0.8~1.2mmol/L in the nano silver reaction liquid C, and the partial size of the nano silver of synthesis is 10 ~30nm.
Preferably, step (4) uses nanoscale aperture active carbon powder, and dosage is 20~50g/m2Bamboo mat is (with bamboo mat face Integrating).
The beneficial effects are mainly reflected as follows: by bamboo mat made from the method for the present invention have strong and broad-spectrum antibacterial, Hypotoxicity, fast light hot, long-term effect, easily disperse, and the characteristics of bacterium will not develop drug resistance.The present invention is in bamboo mat back side fibre Active carbon is wrapped up in the inside of cellulose fiber, captures in time to the formaldehyde of the release in bamboo mat glue-line and auxiliary material, so that finished product formaldehyde Burst size reaches standard requirements, and raw material sources are wide, cheap and easy to get, environmentally protective, reaction condition is mild, before having important application Scape.
