Problems solved by technology

The fuel consumption cost of this method is relatively large, and the equipment investment is relatively large
[0015] The above cleaning treatment methods are all realized by transforming the exhaust device on the production line, installing energy recycling devices, and waste recycling devices. Therefore, these methods have large investment, high maintenance costs, and a large amount of raw materials used. Popularization and application More difficult and other disadvantages

Embodiment 1

[0038] First, mix and grind 1 part of azodicarbonamide, 0.6 part of benzenesulfonyl hydrazide and 0.6 part of sodium bicarbonate to more than 600 meshes to become special foaming additives, then mix 100 parts of polyvinyl chloride resin, 2 parts of dilauric acid Put di-n-butyltin, 70 parts of bis(2-ethylene)ethyl phthalate, 1 part of simethicone, 12 parts of calcium carbonate and ground foaming additives into a high-speed mixer and mix for 3 minutes. Unloading; then put the mixed material into the internal mixer, masticate for 2 minutes at 175°C, and then put it into a double-roller plastic mixer with a constant temperature of 160°C to form a molten sheet; put the molten sheet into Carry out calender molding on the calender, and combine the substrate of the gluing machine (auxiliary machine) to form a rubber cloth; foam the formed rubber cloth through a foaming furnace at 195°C for 1 minute; the foamed rubber cloth is surface modified, rolled and obtained the final product. T...

Embodiment 2

[0040] First, mix and grind 2 parts of azodicarbonamide, 3 parts of 4,4'-oxobisbenzenesulfonyl hydrazide, and 20 parts of calcium oxide to a size above 600 mesh to become a special foaming additive, and then mix 100 parts of polyvinyl chloride Resin, 3 parts of di-n-butyltin dilaurate, 70 parts of di(2-ethylene) ethyl phthalate, 10 parts of diisooctyl azelate, 2 parts of ethyl silicone oil, 15 parts of kaolin and ground hair Put the special foam additive into the high-speed mixer, mix for 3.5 minutes, and unload; then put the mixed material into the internal mixer, masticate at 160°C for 2.5 minutes, and then put it into a double-roller masticator with a constant temperature of 150°C Make it form a molten sheet material; calender the molten sheet material on a calender, and combine it with the substrate of the pasting machine (auxiliary machine) to form a rubber cloth; pass the formed rubber cloth through a foaming furnace at 185 ° C. Soak for 0.5 minutes; the foamed adhesive ...

Embodiment 3

[0042] First, mix and grind 2 parts of p-4,4'-oxobis(benzenesulfonylsemicarbazide), 3 parts of p-toluenesulfonyl hydrazide, 1 part of ammonium bicarbonate, 2 parts of zinc oxide, and 2 parts of stearyl alcohol to 600 mesh The above becomes a special foaming agent, and then 100 parts of polyvinyl chloride resin, 3 parts of di-n-octyltin maleate, 1 part of zinc stearate, 60 parts of bis(2-vinyl)ethyl phthalate, 20 parts Put 20 parts of diisooctyl azelate, 20 parts of calcium carbonate and ground special foaming additives into a high-speed mixer, mix for 4 minutes, and unload; then put the mixed materials into an internal mixer, and Plasticizing at 175°C for 3 minutes, and then put into a double-roller plastic mixer with a constant temperature of 170°C to form a molten sheet material; the molten sheet material is calendered on the calender, and combined with the basic paste machine (auxiliary machine) The sheet is formed into a tape; the formed tape is foamed in a foaming furnace...

Abstract

The invention discloses an energy-saving and emission-reduction method for a production line of PVC artificial leather, comprising the following steps: mixing and grinding high-temperature chemical foamer with low-temperature chemical foamer, or the high-temperature chemical foamer with a foaming accelerant, or the high-temperature chemical foamer, the low-temperature chemical foamer and the foaming accelerant; then mixing with PVC resin, a thermal stabilizing agent, a plasticizing agent and filling material and stirring; and then gelling, plasticating, pressing, rolling, jointing with base cloth to form adhesive tape; putting the formed adhesive tape into a foaming furnace; foaming for 0.5 to 1.5 minutes at the temperature of 185 DEG C to 195 DEG C and decorating the surface to obtain a product. Since the low-temperature foaming or / and direct foaming acceleration of the low-temperature chemical foamer or / and the foaming accelerant is used, the high-temperature chemical foamer begins to foam at lower temperature, thereby reducing the foaming temperature, achieving the purpose of reducing the energy consumption and the harmful gas, especially reducing the emission of the harmful gasand the heat energy produced by the high-temperature volatilization of the plasticizing agent.

Description

technical field [0001] The invention belongs to the technical field of energy saving and emission reduction in the production process of PVC artificial leather, and is a new method capable of reducing energy loss in the production process of PVC artificial leather, reducing the generation and discharge of plasticizer organic substances, controlling pollution, reducing production costs, and improving the quality of artificial leather products. method. Background technique [0002] Artificial leather products are widely used in our daily life, such as interior decoration, sofa fabrics, car interiors, clothing, footwear, bags, handbags, etc. Many are artificial leather products. PVC artificial leather is made of polyvinyl chloride, polychloride and other resins as coatings, and cloth as the base material, and most of them are foamed products. The cell quality of foamed products is an important aspect to measure the quality of foamed artificial leather. Artificial leather with...
