Abstract
The invention discloses antibacterial synthetic leather, which is prepared from an antibacterial agent into slurry by a rolling method. The antibacterial slurry consists of the following components in parts by weight: 100 parts of polyvinyl chloride (PVC) resin powder, 10 to 20 parts of thermoplastic polyurethane (TPU) resin, 6 to 12 parts of antibacterial agent, 40 to 60 parts of epoxy soybean oil, 2 to 10 parts of color cake, 4 to 8 parts of stabilizing agent and foaming agent and 10 to 40 parts of ultrafine filler. The synthetic leather is relatively high in mechanical property and has an antibacterial characteristic.
Description
Technical field
The invention belongs to synthetic leather and make the field, be specifically related to a kind of antibiotic synthetic leather and this antibiotic synthetic leather preparation method.
Background technology
Synthetic leather is the substitute of inventing the earliest for the cortex fabric, and it is to be compounded on the cloth with the auxiliary agent calendering that PVC adds plasticizer and other to make.Be mainly used in case and bag, decoration, sofa, this synthetic leather be along with environment for use can be infected with harmful bacterium, and can inherit breeding in the above and increase, and by the contact cross infection of human body, constantly propagates again, and health is worked the mischief.
Summary of the invention
The purpose of this invention is to provide a kind of synthetic leather that possesses antibacterial action.
Another object of the present invention provides a kind of preparation method of above-mentioned antibiotic synthetic leather.
Purpose of the present invention can reach by following measures:
A kind of antibiotic synthetic leather, this synthetic leather utilization add the antiseptic slurry and adopt rolling process to be prepared from, and described antibiotic slurry is made into by the component of following weight portion:
Wherein polyvinyl chloride resin is the SG-5PVC resin, i.e. S-5 type generated by polyvinyl chloride by calcium carbide; The polyvinyl chloride resin powder refers to the powder of S-5 type generated by polyvinyl chloride by calcium carbide resin, to a powder material without specific (special) requirements.
The TPU resin is TPU(Thermoplastic polyurethanes), and its a kind of plasticizer as polyvinyl chloride resin uses.
Wherein said antiseptic refers to and can within a certain period of time, make growth or the breeding of certain micro-organisms (bacterium, fungi, saccharomycete, algae and virus etc.) remain on chemical substance necessary below horizontal.Antiseptic is that a class has antibacterial and New-type adjuvant bactericidal property.With the anti-microbial property that has further improved antibiotic slurry after other components (such as plasticizer and ultra-fine filling material) synergy.It is the general antibacterial matrices of antibacterial mildew inhibitor HSA-FAM, SHT or antibacterial mildew inhibitor RHA-M-1 that antiseptic among the present invention preferably adopts silver.
Epoxidized soybean oil as main plasticizer, and can be avoided pollution to environment in this antibiotic synthetic leather.
The look cake is synthetic leather manufacturing look cake commonly used, according to the different colours requirement, selects.
Stabilizing agent, blowing agent are for commonly using the auxiliary agent of synthetic leather production usefulness, wherein stabilizing agent is preferably potassium zinc stabilizer, barium zinc stabilizer or PVC compound stabilizer, and blowing agent is preferably Celogen Az (being blowing agent AC) or contains the mixture of Celogen Az.
Ultra-fine filling material is 2000 orders above (namely crossing 2000 orders or higher order) calcium carbonate superfine powders.Through repeatedly research discovery, calcium carbonate superfine powder adds in the synthetic leather, because material character and small-size effect, make it have the effect of similar modifier, in certain amount ranges, cooperate the mechanical mechanics property that can obviously improve the PVC material with other components, but add to a certain amount of after, the mechanical properties decrease of material.The preferred group of ultra-fine filling material in prescription becomes 20～40 parts.
Above-mentioned rolling process is traditional rolling process, is about to each raw material of antimicrobial form PVC slurry in first banburying under 145～155 ℃ after 100～150 ℃ of lower high-speed stirred, obtains the antimicrobial form slurry; Base material is in 140～160 ℃ of lower upper PU (polyurethane) slurries, then be incorporated into again banburying under 155～165 ℃ with described antimicrobial form slurry, entering 4-roll calender after the banburying, to press down Yangjing in 160～190 ℃ whole, and the embossing of foaming under 160～180 ℃ is at last processed.
The preparation method of antimicrobial form synthetic leather of the present invention is specially: first each raw material (component) of antimicrobial form slurry is entered banbury after the homogenizer high speed stirs and carry out banburying, obtain the antimicrobial form slurry; Then PU slurry on the base material is combined in again banburying in the banbury with described antimicrobial form slurry, and it is smooth to enter 4-roll calender calendering after the banburying, enters at last the embossing of foaming of foamed printing machine and processes; Each raw material of wherein said antimicrobial form and weight portion proportioning thereof such as above-mentioned institute.
Wherein the temperature during high-speed stirred is 100～150 ℃; First banburying temperature is 145～155 ℃; Base material is in 140～160 ℃ of lower upper PU slurries; Temperature during banburying is 155～165 ℃ again; Rolling temperature is 160～190 ℃; Foaming embossing treatment temperature is 160～180 ℃.
The synthetic leather antibiotic property generally can obtain by increasing antibiotic consumption.But because the compatibility of general antibiotic plasticizer and PVC is very not good, take to add the TPU TPU(Thermoplastic polyurethanes) in this prescription, TPU and PVC good characteristic have been given full play to, both can be used as the PVC plasticizer had been used, eliminate the migration of plasticizer that the part polyvinyl chloride exists, volatilization and cause product, prevent from along with the migration of plasticizer antiseptic progressively being disappeared and ineffective; Add simultaneously ultra-fine filling material and can further strengthen Leather Properties.In the antibiotic slurry of the present invention under the synergy of each component, make the PVC material anti-microbial property antibiotic permanent effect.
