Description

A kind of low energy consumption ecological artificial leather manufacturing method

technical field

The invention belongs to the field of synthetic leather manufacturing, and specifically refers to a low-energy-consumption ecological artificial leather manufacturing method.

Background technique

my country is the largest producer and consumer of imitation leather in the world. In 2012, there were more than 3,000 imitation leather-related enterprises (more than 300 enterprises above designated size), 1,575 production lines, and an output of 7.8 billion square meters, accounting for 73% of the world's total output. As the first generation of imitation leather products, polyvinyl chloride (PVC) artificial leather has the characteristics of bright color, high strength, wear resistance, folding resistance, acid and alkali resistance, low cost and convenient processing. It has been widely used in bags , furniture, automotive interiors, floors, wallpapers and other fields. According to statistics, from 1997 to 2012, the production scale of PVC artificial leather in my country continued to expand, and the import volume dropped from 315 million meters to 42 million meters, while the export volume increased from 48 million meters to 327 million meters, successfully transforming into a world It is a major exporter of PVC artificial leather, and its products are exported to the European Union, North America, Southeast Asia, South Africa and other regions.

However, with the increasing awareness of people's ecology and the strict control of pollution and energy consumption in various countries in the world, my country's artificial leather industry lags behind in the adjustment of technology and product structure. The industry's economic growth is deeply rooted at the cost of high pollution and high energy consumption, which has caused the market competitiveness of "Made in China" to decline sharply in recent years, and the industry's traditional export advantages are facing unprecedented severe challenges. In fact, the key technical bottlenecks currently affecting the ecological level of PVC artificial leather in China mainly exist in the following three aspects: First, plasticizers are necessary raw materials for the manufacture of PVC artificial leather surface layers and foam layers, and currently the most widely used plasticizers— — Phthalates are considered to have toxicity and carcinogenic risks, and direct contact with the human body, especially sensitive groups, may induce diseases; second, adhesives are usually required to be bonded between PVC and the base fabric to improve the peel strength, while for To improve the surface color, effect or brightness of finished leather, semi-finished crust leather must also be surface treated. Traditional adhesives and surface treatment agents are solvent-based resins. Due to the complex composition of solvents in the slurry (including dimethylformamide, toluene, methyl ethyl ketone, ethyl acetate, etc.), there is currently no effective recycling method and Technology controls its emission, and the organic solvent residues in the finished leather are also widely criticized (solvents such as dimethylformamide and toluene have been listed as substances of high concern by the European Union), which have become an important factor affecting the ecological grade of PVC artificial leather. Third, in order to endow the finished leather with characteristics such as lightness, thickness, plumpness, and soft touch, a foaming layer is usually added between the surface layer and the adhesive layer of PVC artificial leather. Azodicarbonamide is currently the most commonly used foaming agent in the manufacture of artificial leather. Its thermal decomposition temperature is as high as 215-220°C. It requires high energy consumption for foaming, and the coating will turn yellow after foaming. It is not suitable for light-colored leather. .
