Relative to the existing method for preparing latex film, the principle of the present invention and gain effect are as follows:
(1) the invention belongs to which meyer sedge fiber and tourmaline powder are applied in Heveatex for the first time, in meyer sedge fiber
The natural products luteolin and its derivative contained has extremely strong inhibiting effect to fungi and bacterium, by meyer sedge fiber to day
The anti-microbial property of prepared compounded latex can be effectively improved in right latex;Using stearic acid modified dose to crude tourmaline powder
Being added in Heveatex after being modified can be such that crude tourmaline powder preferably dissolves in Heveatex and sustained release
Anion and far infrared, the anion that it is discharged also have the function of antibacterial bacteriostatic, in addition, the far infrared that it is discharged
The energy field collectively formed with anion can provide energy to human body, and human body cell is made to be converted into motion state by dormant state,
Promote human metabolism, vivotoxin, balanced human's pH value, to play the role of health care and treatment is discharged.Therefore, will
Meyer sedge fiber and tourmaline powder liquid are applied to antibacterial vulcanized latex prepared by energy in Heveatex and not only remain natural gum
The excellent comprehensive performance of cream also has good anti-microbial property and healthcare function, can be widely applied to various latex products
In production.
(2) primary raw material selected by preparation method of the invention is natural products, environmentally protective, simple and easy to get.
(3) preparation method of the invention also has simple and easy, mild condition and easily controllable etc..
Specific embodiment
Further below in conjunction with the embodiments with the present invention will be described in detail.It will similarly be understood that following embodiment is served only for this
Invention is further described, and should not be understood as limiting the scope of the invention, specific quality, reaction time in example

Tourmaline powder/meyer sedge fiber-antibacterial latex film preparation method, specifically comprises the following steps:
(1) preparation of modified Nano tourmaline powder
60g nano-tourmaline powder (average-size 40nm-60nm) is added to stirring in 140ml water and is configured to quality point
In 60 DEG C of stirring 25min stearic acid (i.e. 1.5g) is added by the 2.5% of tourmaline powder mass fraction, institute in the slurry of number 30%
Mixture continue stir 30min be modified, obtained solid, which is dried, after filtering can be prepared by modified Nano tourmaline
Powder;
(2) 1000g natural gum (weight weight by dry rubber) is added to the modified Nano tourmaline powder prepared in 40g step 1)
In, after 40 DEG C of uniform stirrings, 7g vulcanizing ingredient is added (by 50% sulphur dispersion of 2g, the dispersion of 40% zinc oxide of 2g
Body, 50% sodium silicofluoride dispersion of 0.5g, 50% promotor ZDC dispersion of 1g, 40% altax dispersion group of 1.5g
At), gained mixture is heated to 75 DEG C and continues agitating and heating 20min, 20g meyer sedge fiber, gained mixing is then added
Object continues heating stirring 20min, is cooled to room temperature and tourmaline powder/meyer sedge fiber-Heveatex multiple emulsion can be obtained.
(3) tourmaline powder prepared/meyer sedge fiber Heveatex multiple emulsion is poured on the glass plate with frame
It is dried and forms a film and parched completely to film, film formation time is 72-96 hours, and then resulting film is put into vacuum oven
It is dry, carry out after cure experiment, after cure temperature is 65 DEG C, and the after cure time is 2 hours, can be prepared by the tourmaline powder/
Meyer sedge fiber-antibacterial latex film.
Antibiotic rate is tested according to Quine's method to synthesized latex film;The result shows that: tourmaline powder/crow prepared by the present invention
It draws grass fiber-antibacterial latex film compared with pure natural latex film, there is following significant effect:
For Escherichia coli, the antibiotic rate of staphylococcus aureus and hay bacillus is increased to by 0%, 0% and 0% respectively
70.3%, 78.5% and 69.5%.
Comparative example 1
Reference implementation example 1 prepares tourmaline powder/meyer sedge fiber-antibacterial latex film preparation method, by meyer sedge fiber
Changing seaweed extracted liquor into, remaining condition is identical, modified Nano tourmaline powder/seaweed extracted liquor-Heveatex compound cutan is made,
The performance test conditions of gained compound cutan examine that test result is as follows with embodiment 1:
For Escherichia coli, the antibiotic rate of staphylococcus aureus and hay bacillus is increased to by 0%, 0% and 0% respectively
21.4%, 32.5% and 27.4%.
Compared with Example 1, being added, there is the seaweed extracted liquor of anti-microbial property to be far to the promotion of Heveatex performance
The effect being modified using meyer sedge fiber to Heveatex is good, especially in terms of anti-microbial property.Therefore, according to the present invention
Preparation method synthesized by tourmaline powder/meyer sedge fiber-antibacterial latex film have excellent antibiotic property also have it is good
Health-care effect can be widely used in latex product.
