Description
Technical field
The invention belongs to polymeric material field, relate to a kind of floor carpet antibacterial pad of fire-retardant insect protected, the present invention also relates to
And the preparation method of this antibacterial pad of fire-retardant insect protected.
Background technology
In recent years, along with the raising of people's living standard, people are to fitting up the requirement of product and decorative product the most increasingly
Height, such as floor and carpet, to providing floor and the product demand of carpet substrate protection and requiring more and more higher, meanwhile, people
Environmental protection and health there is the highest more urgent demand.
In house decoration, people select solid wooden floor board mostly, have become the most hidden, area is maximum, least below floor
The indoor environmental pollution source easily administered, forms a health being difficult to take into account, ignored by people dead between ground, ground cushion and floor
Angle, condenses biology, the microorganisms such as pathogenic bacteria, worm, demodicid mite, ant, directly threatens the healthy of people.Existing processing method is
Traditional pesticide is spread in face under floor, although this method control of insect pests is useful, but parasite killing itself has toxic and side effects,
Even by the detection of agricultural sector and obtain production permit, also it is only limited to agricultural and forestry production and other specific uses and does not permits
Permitted to be applied to family and played habitat environment use.Another corner or spot as yet untouched by a clean-up campaign is exactly in home decoration, and people like laying on the ground
Carpet, carpet, owing to not moving for a long time, easily grows pathogenic bacteria, worm, demodicid mite, ant etc. as below floor below carpet.
Floor and carpet are as the main material of Household fit-up and decoration, and the raising of its security performance is always people and generally closes
The problem of note, but floor and carpet also exist inflammable potential safety hazard, threaten the life security of people, it is possible to people can be given

The floor carpet of the present invention antibacterial pad of fire-retardant insect protected uses Chinese medicine antibacterial additive and natamycin Chinese medicine and western medicine to enter
Row is compounding, and natamycin acts on cell wall or cell membrane system, both can the most effectively suppress various mycete, saccharomycetic life
Long, the generation of mycotoxin, Traditional Chinese Medicine Anti microbial inoculum can be suppressed again to may act on extracellular microbial outer structural layer, affect the fortune of microorganism
Dynamic, cross-film matter transportation or biochemical reaction etc., thus reach fungistatic effect, two class antibacterial agent combination use, antibacterial, sterilize, drive
Worm, anticorrosion combine, and can act on antibacterial, mycete, reach the effect of higher bactericidal mildew-resistant, and have in terms of two
There is good anthelminthic effect.
The present invention also provides for a kind of floor carpet preparation method with the antibacterial pad of fire-retardant insect protected, comprises the following steps:
(1) by after Maifanitum mixing coarse pulverization, under high temperature, heat 1h, be then put in quenching in cold water, then carry out ultra micro
Pulverize, cross 325 mesh sieves, obtain Maifanitum superfine powder；
(2) Maifanitum superfine powder prepared by step (1) is added the aqueous acetone solution of 10 times of its weight, stirring, then
Add silane coupler and monoglyceride, in 60 DEG C of water-baths after constant temperature stirring 4h, stand 12h, filtration washing, after drying, must change
Property Maifanitum superfine powder；
(3) modified Maifanitum superfine powder prepared by natamycin, Chinese medicine additive and citric acid and step (1) is placed in stirs
Mix in machine, after mix homogeneously, add beta-schardinger dextrin-and chitosan, discharging after cladding dispersion 30min, obtain cladding antibacterial；
(4) Low Density Polyethylene and high density polyethylene (HDPE) are put in mixing plant, be heated to 150 ± 5 DEG C, and stir
Mix to the most melted, add decabromodiphenyl oxide, polyvinyl resin, Tissuemat E, Masterbatch, continue heated and stirred uniform, obtain molten
Body A；
(5) the melt A that step (4) prepares is proceeded in twin (double) screw extruder, be then sequentially added into zinc stearate, three oxidations
Two antimony, monoglyceride and step (3) prepare cladding antibacterial carry out melting mixing 1h after, by foaming agent in the middle part of extruder with height
The mode that pressure injection enters is injected in extruder, proceeds melting mixing, to plastifying mix homogeneously；
(6) by the mixed material extrusion molding of step (5) plasticizing mix homogeneously, after cooling down, draw, flatten, being wound around,
Obtain the described floor carpet antibacterial pad of fire-retardant insect protected.
Further, in the aqueous acetone solution described in step (2), the mol ratio of acetone and deionized water is 1:(1-3).
Further, the preparation method of the Chinese medicine additive described in step (3) is: weigh Herba et Flos Pyrethri Cinerariifolii, Pericarpium Granati, hardship
Chinaberry skin, Pericarpium Zanthoxyli, Rhizoma Acori Graminei, Radix Arnebiae (Radix Lithospermi), Camphora, gross weight is designated as 1 part, adds 6 parts of purified water, soaks 1h at 50 ± 5 DEG C, the least

Dynamic, cross-film matter transportation or biochemical reaction etc., thus reach fungistatic effect, two class antibacterial agent combination use, antibacterial, sterilize, drive
Worm, anticorrosion combine, and can act on antibacterial, mycete, reach the effect of higher bactericidal mildew-resistant, and have in terms of two
There is good anthelminthic effect.
2) in the preparation method of the present invention, after Maifanitum coarse pulverization, heat under high temperature, be then put in quenching in cold water
Carrying out micronizing again, make the Maifanitum can be with easier crushed, and grinding particle size be little and uniform, ore utilization rate
High；Then Maifanitum silane coupler and the monoglyceride of pulverizing are carried out surface modification, increase the active site on Maifanitum surface,
Then, after natamycin, Chinese medicine additive and citric acid being mixed homogeneously with modified Maifanitum superfine powder, beta-schardinger dextrin-is added
Being coated with chitosan, the cladding antibacterial obtained can realize the slow release of antibacterial, has the effect of long-acting bactericidal,
And can improve stability and the bioavailability of Traditional Chinese Medicine Anti microbial inoculum, chitosan and through the modified wheat meal with more active site
Stone can also preferably adsorb antibacterial to product surface, is more beneficial for bactericidal.
3) in the preparation method of the present invention, carry out batch mixing by twin screw extrusion process, improve cladding antibacterial at this
Dispersing uniformity in product, and with the addition of the compositions such as decabromodiphenyl oxide, polyvinyl resin, zinc stearate, antimony oxide, carry
While high Product processing performance and melt fluidity, also impart the fire resistance that product of the present invention is good, make this product
There is good anti-flammability.
4) product of the present invention is green product without environmental pollution, has high flame retardant, and insect protected bacteriostasis property is good, can not only long time
Between suppress growing of pathogenic bacteria, worm, demodicid mite, ant etc., sterilization, mildew-resistant, anthelmintic, can effectively protect floor carpet, strengthen its use longevity
