Description
Technical field
The invention belongs to synthetic leather and make the field, be specifically related to a kind of anti-aging synthetic leather and this anti-aging 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.Present domestic PVC decorates in the synthetic leather production process, usually adopt plasticizer, polyvinyl chloride resin powder, coarse whiting, stabilizing agent, blowing agent, etc. main raw material form.This synthetic leather in process of production particularly surface treatment process and organic solvent easily produce static, cause fire, and easily aging, affect the use of synthetic leather.
Summary of the invention
The purpose of this invention is to provide a kind of synthetic leather that uses under the situation that possesses.
Another object of the present invention provides a kind of preparation method of above-mentioned anti-aging synthetic leather.
Purpose of the present invention can reach by following measures:
A kind of anti-aging synthetic leather, this synthetic leather utilization add the age resister slurry and adopt rolling process to be prepared from, and described anti-aging 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.
Age resister of the present invention adopts 2-hydroxyl-4 oxy-octyl benzophenone, hindered amine as light stabilizer 770, hindered amine as light stabilizer 622 or hindered amine as light stabilizer GW-540.
Epoxidized soybean oil as main plasticizer, and can be avoided pollution to environment in this anti-aging 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, cooperates the electric conductivity that can obviously improve the PVC material with other components, but owing to there not being low vitrification point, effect there is not modifier obvious, and add to a certain amount of after, the antistatic of material can rise.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 anti-aging type PVC slurry in first banburying under 145～155 ℃ after 100～150 ℃ of lower high-speed stirred, obtains anti-aging type slurry; Base material is in 140～160 ℃ of lower upper PU (polyurethane) slurries, then be incorporated into again banburying under 155～165 ℃ with described anti-aging type 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 anti-aging type synthetic leather of the present invention is specially: first each raw material (component) of anti-aging type slurry is entered banbury after the homogenizer high speed stirs and carry out banburying, obtain anti-aging type slurry; Then PU slurry on the base material is combined in again banburying in the banbury with described anti-aging type slurry, enters 4-roll calender calendering after the banburying smooth, enters at last the embossing of foaming of foamed printing machine and processes; Each raw material of wherein said anti-aging type 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 ℃.
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 the product mummification, easily produce static, easily aging effect, while further adds age resister, and the UV resistant irradiation of leather was reached more than 3000 hours; Add simultaneously ultra-fine filling material and can further strengthen Leather Properties.
