The invention also discloses a kind of preparation methods of antibacterial tatami, comprise the following steps：
The first step prepares antiseptic, by 70-85 parts of zeolite with carrying silver, 1-2 parts of silver-loaded zirconium phosphates, 5-8 parts of isothiazolinone, 2-5 parts Guazatine acetate, 1-5 part titanate coupling agent, 1-5 parts of polyurethane based resins, 2-3 parts of pyrithiones are uniformly mixed, and in Agitating and heating 2h in 300-400 DEG C, grind into powder is up to antiseptic after cooling；
Second step prepares weft, first by normal activated carbon in nitrogen protection, 1200-2000 DEG C of roasting 10-24 h, to carry out For graphitization processing so as to obtain modified activated carbon, the graphitization component content wherein in modified activated carbon accounts for the 20- of its gross mass 40%, then by 80-90 parts of polylactic acid, 20-30 parts of Vinyon Ns, 10-20 parts of polypropylene fibre, 1-5 parts of antiseptics, 3-5 parts of coupling agents, 2-5 Part silicon fluoride and 1-2 parts of modified activated carbons are uniformly mixed, and are obtained at 200-220 DEG C after double-screw extruding pelletizing, wire drawing Weft；
3rd step prepares warp, first by ball milling after 70 parts of opal, 20 parts of rare earth, the mixing of 10 parts of diatomite disperse 1 it is small when obtain Then 40-85 parts of viscose glue sections, 20-30 parts of spandexs, 5-10 parts of dispersants and 1-5 parts of modifying agent are uniformly mixed by modifying agent, At 250-300 DEG C warp is obtained after double-screw extruding pelletizing, wire drawing；
4th step prepares latex mattress, first by 50-60 parts of styrene-butadiene block copolymer elastomers, 20-30 parts of acrylonitrile- Butadiene-styrene copolymer elastomer, 5-10 parts of ethylene-octene copolymer elastomers, 2-5 parts of ethylene propylene diene rubbers, 1-5 parts Accelerating agent, 5-10 a part filler are uniformly mixed, in 200 DEG C of heating reaction 30min, up to high resiliency agent after cooling, then by 40-50 parts Natural emulsion, 30-50 part artificial latex, 1-8 parts of polyurethane, 3-5 parts of antioxidants, 1-3 parts of foaming agents, 1-5 parts of high resiliency agent It is mixed evenly and latex material is made, wherein the rotating speed of mixer is 1200 turns/min, mixing time 20min, Ran Houjing Cross foaming, injection, boiling, cooling obtain latex mattress；
5th step, prepares anti-skid cloth, by 30-40 parts of nitrile rubbers, 20-30 parts of poly- butadiene-styrene rubber, 10-15 parts of butadiene rubbers, 10- 15 parts of carbon blacks, 5-8 parts of zinc oxide, 1-3 parts of stearic acid are poured into inside mixer and are kneaded, time 15min, temperature 120- 140 DEG C, into material, 1-5 parts of vulcanizing agents of addition are kneaded again after cooling of then coming out of the stove, time 5min, after 50-70 DEG C of temperature Skid resistant course is obtained, above-mentioned skid resistant course is then coated in the bottom surface of anti-skid cloth；
6th step prepares antibacterial tatami, above-mentioned warp and weft is woven to obtain tissue layer on braider, are then wrapped The top of above-mentioned latex mattress is overlayed on, and anti-skid cloth is coated in the lower section of latex mattress, you can obtains antibacterial tatami.
The weft is to mix polylactic acid, Vinyon N, polypropylene fibre, can take the advantages of respective, so as to improve latitude The intensity of line, wear-resistant and antibiotic property.Wherein acid fiber by polylactic passes through the chemical polymerization of lactic acid Cyclodimerization object or lactic acid Direct polymerization can obtain the polylactic acid of high molecular weight.Using the product that polylactic acid is obtained as raw material, there is good bio-compatible Property and Bioabsorbable and biocidal property, antibiotic property.Vinyon N is acrylonitrile monemer and the vinyl chemical combination containing antiseptic elements Object is copolymerized, and has similar fleecy feel and high antibiotic property, and with acidproof and chemically-resistant medicament.Polypropylene fibre intensity Height, relative density is light, there is preferable chemical resistance.
Zeolite with carrying silver and silver-loaded zirconium phosphate in the antiseptic, are respectively provided with preferable inorganic antiseptic, isothiazolinone It is efficient organic antibacterial agent with guazatine acetate, pyrithione, titanate coupling agent can be by above-mentioned inorganic antiseptic It is bound up with organic antibacterial agent, and the promotion of antibacterial effect is improved by polyurethane based resin, above-mentioned inorganic antiseptic Between organic antibacterial agent there is synergistic effect, further function as the effect of antibacterial.
For the coupling agent for being coupled polylactic acid, Vinyon N, polypropylene fibre, the stretching that the silicon fluoride is then used for improving weft is strong Degree.The modified activated carbon refers to the graphited activated carbon in part, and graphitization component content accounts for the 20-40% of its gross mass, described Graphited activated carbon can be used as carrier, using the electron transfer characteristic of graphite-structure, improve the active ingredient in antiseptic It is played, strengthens antibacterial effect.
The warp is mixed to prepare by viscose glue section and spandex, and wherein viscose rayon has good hygroscopicity, has light Slide the characteristics such as nice and cool, ventilative, antistatic, dyeing is gorgeous.Spandex fibre has high resiliency, high restorative, have it is preferable it is acidproof, The properties such as alkaline-resisting, fast light.Dispersant and modifying agent are added, for improving the characteristic of warp, is particularly diatom in the modifying agent Soil be used as carrier so that opal and rare earth can be adsorbed in diatomaceous surface volume, and opal and rare earth then as bear from Sub- powder is used to discharge anion.It, can be with the water such as the sweat of skin surface when the direct skin contact of negative ion powder and human body Divide reaction, so as to accelerate the release of anion.Negative ion powder can penetrate blood-brain barrier and enter cerebrospinal fluid, adjust cerebral cortex work( Can, excited and depression is made to tend to balance.By reconciling the level of human body endorphin pituitary and interferon, calm, town is played Pain acts on.
Using natural emulsion and artificial latex as primary raw material in the latex mattress so that the latex mattress has higher bullet Property, polyurethane is added, then convenient for shaping, while adds antioxidant, extends its service life.
High resiliency agent in the latex mattress, with styrene-butadiene block copolymer elastomer, acrylonitrile-butadiene- Elastomer based on styrenic copolymer elastomers, ethylene-octene copolymer elastomer, coordinates with ethylene propylene diene rubber and promotion Agent provides elasticity, so that a variety of elastomers can play a role jointly, it is final to improve whole elasticity.
Nitrile rubber, poly- butadiene-styrene rubber, butadiene rubber in the skid resistant course have stronger anti-skidding effect, can prevent Tatami shifts, and in addition carbon black, zinc oxide are as additive, and for improving the thermoplasticity of skid resistant course, stearic acid is anti-for enhancing Sliding effect.
