Abstract
The invention discloses a low energy consumption ecological leatheroid preparation method. The preparation method adopts an environmental-friendly plasticizer to replace a phthalate noxious plasticizer to prepare a PVC surface layer and a foam layer, utilizes a low temperature foaming agent with a foaming temperature ranging from 160 DEG C to 190 DEG C to replace the conventional azodicarbonamide (AC) high temperature foaming agent to foam on the foaming layer, and finally uses an environmental-friendly aqueous resin as a base cloth glue and a PVC surface treating agent, as a result, the low energy consumption ecological leatheroid preparation method is obtained. The discharging and residue of the noxious plasticizer and an organic solvent are avoided by using the environmental-friendly plasticizer, as a result, the ecological grade of the finished leatheroid is improved; the application of the low temperature foaming agent can remarkably lower the energy consumption caused by the leatheroid preparation, the production cost is saved, meanwhile, the foam holes are fine and uniform, destructive air holes are avoided, and the color is fleet and weak. By adopting the process, the prepared leatheroid has the characteristics that the cost is low and the content of the volatile organic substance is lower than 5 mg/kg, satisfies quality requirement of EU ecological leatheroid, and remarkably improves the international market competitiveness and the environmental protection grade of the leatheroid.
Description
Technical field
The invention belongs to synthetic leather and manufacture field, specifically refer to a kind of low energy consumption ecological artificial leather manufacture method.
Background technology
China is world Fang Ge production and consumption big country.2012, the total imitative relevant enterprise family more than 3000 (family more than 300 of the above enterprise of scale) that removes from office in the whole nation, 1575 of production lines, output reaches 7,800,000,000 square meters, accounts for 73% of Gross World Product.As the imitative leather of first generation product, polyvinyl chloride (PVC) artificial leather has that lovely luster, intensity are high, wear-resisting, folding, the good characteristic of resistance to acids and bases, and with low cost, easy to process, be now widely used in the fields such as case and bag, furniture, automotive trim, floor, wallpaper.There is statistics to show, from 1997 to 2012, China PVC artificial leather production scale continues to expand, import volume drops to 0.42 hundred million meter from 3.15 hundred million meters, export volume rises to 3.27 hundred million meters from 0.48 hundred million meter, success makes the transition as world PVC artificial leather big export country, and product is found a good sale in the areas such as European Union, North America, Southeast Asia, South Africa.
Yet, along with day by day strengthening and the strict control of countries in the world to pollution, energy consumption of people's ecological awareness, Chinese people fabricate-leather industry seriously lags behind in the adjustment of technology and product structure, the Green Trade Barrier that enterprise faces the areas such as European Union, America and Japan lacks consciousness and initiative, industrial economy increases that to take the situation that high pollution and high energy consumption be cost deep-rooted, cause the market competitiveness of " made in China " significantly to glide in recent years, traditional trump-cards in the export of of the sector are just suffering unprecedented severe challenge.In fact, mainly there is following three aspects: in the key technology bottleneck of the domestic PVC artificial leather ecological grades of impact at present: first, plasticizer is the necessary raw material that PVC artificial leather surface layer and foaming layer are manufactured, and current the most widely used plasticizer---phthalate is considered to exist toxicity and carcinogenic risk, especially responsive colony directly contacts and may induce an illness with human body; Between the second, PVC and base cloth, conventionally need bonded adhesives bonding to improve peel strength, and for improving finished leather surface color, effect or light degree, semi-finished product crust leather also must carry out table place.Tradition bonded adhesives and surface conditioning agent are solvent type resin, due to the solvent composition in slurry complicated (containing dimethyl formamide, toluene, butanone, ethyl acetate etc.), there is no at present effective recoverying and utilizing method and technology controls its discharge, and organic solvent residual in finished leather also widely denounces (dimethyl formamide, toluene equal solvent Yi Bei European Union classify high attention rate material as), become the key factor that affects PVC artificial leather ecological grades.The 3rd, for giving the characteristics such as finished leather is light, abundant, plentiful, soft, in the middle of the surface layer of PVC artificial leather and adhesive linkage, conventionally also increased a foaming layer.Celogen Az is the most frequently used blowing agent during current artificial leather is manufactured, and its decomposes temperature is up to 215-220 ℃, and the required energy consumption that foams is high, and after foaming, coating yellowing is serious, unsuitable to light color leather.
