Production equipment and process of waterborne polyurethane foaming velvet-feeling silk-feeling synthetic leather

Abstract

The production equipment comprises a kettle body, a plurality of supporting legs are arranged on the wall body of the bottom of the kettle body, a feeding pipe is arranged on the wall body on one side of the top of the kettle body, and a pressure gauge is arranged on the wall body, located at the front end of the feeding pipe, of the top of the kettle body; a machine base is arranged on the wall body at the central position of the top of the kettle body, a first motor is arranged on the wall body at the top of the machine base, the first motor is electrically connected with an external controller, and a second motor is further arranged on the wall body above one side of the kettle body. The invention discloses production equipment and process of waterborne polyurethane foaming velvet-feeling silk-feeling synthetic leather, and relates to the technical field of synthetic leather equipment. Four screw rods can be driven to rotate synchronously through a second motor and an adjusting ring arranged on the outer wall of a kettle body; and through a cavity in the screw rod and a sealing gasket, the interior of the kettle body can be conveniently sprayed and cleaned through water flow.

Description

technical field [0001] The invention relates to the technical field of synthetic leather equipment, in particular to a production equipment and a process for water-based polyurethane foamed velvet-feeled synthetic leather. Background technique [0002] Synthetic leather is a term relative to "leather" (ie genuine leather), also known as artificial leather and synthetic leather. At present, the production process of oily and water-based synthetic leather is generally filmed and then post-treated, mainly because of the wear resistance of the product. The fastness is not enough, and the wear fastness of the surface can only be increased by filming, but the feel of synthetic leather will be affected after filming, and the cost will also be greatly increased. Therefore, the resistance of synthetic leather will be increased by adding polyurethane fluff powder or polyurethane elastic powder. Grinding and feel. [0003] In addition, polyurethane fluff powder or polyurethane elastic...

Problems solved by technology

[0002] Synthetic leather is a term relative to "leather" (that is, real leather), also known as artificial leather and synthetic leather. At present, the production process of oily and water-based synthetic leather is generally post-treatment after filming, mainly because of the wear resistance of the product. The fastness is not enough, and the only way to increase the wear fastness of the surface is through filming, but the synthetic leather will affect the feel after filming, and the cost will also increase significantly. Therefore, the durability of synthetic leather will be increased by adding polyurethane fluff powder or polyurethane elastic powder. Grindness and touch

[0003] Moreover, polyurethane fluff powder or polyurethane elastic powder is mixed through a reaction mixing container such as a reaction kettle, and after most of the reaction kettles are used, because the inside of the kettle body contains a stirring mechanism, and the cavity inside the kettle body is relatively airtight, no Conducive to the post-cleaning of the reactor
