Problems solved by technology

[0005] (1) Polyester polyol needs to react under high temperature conditions, while the traditional reaction kettle has certain thermal conductivity, the heat in the kettle body is easy to flow to the outside, heat exchange with the outside world, the temperature uniformity in the kettle body is poor, and the stability of the reaction needs improvement
[0006] (2) When materials A and B are mixed and stirred in the stirring tank, due to the rapid crosslinking of materials A and B after mixing, the mixture has a high viscosity and is easy to adhere to the inner wall of the kettle body, resulting in uneven stirring and affecting The amount of output, and at the same time bring inconvenience to the subsequent cleaning
In addition, when some viscous materials are stirred by the rotation of the stirring paddle, a longer stirring time and a larger motor power are required, and the stirring efficiency needs to be improved.
[0007] (3) Polyurethane is used as an adhesive on shoe leather, especially sports shoe leather. After the shoe leather is worn for a long time, the dry layer on the surface of the shoe leather will crack or fall off from the wet layer, which will affect the use of shoe leather. Longevity, adhesive performance needs to be improved

Description

technical field [0001] The invention relates to the technical field of polyurethane, in particular to a production device and a production method of a two-component polyurethane adhesive. Background technique [0002] The full name of polyurethane is polyurethane, which is a general term for macromolecular compounds containing repeated carbamate groups on the main chain. The mechanical properties of polyurethane are highly adjustable. By controlling the ratio between crystalline hard segments and non-crystalline soft segments, polyurethanes can obtain different mechanical properties. Therefore, its products have excellent properties such as wear resistance, temperature resistance, sealing, sound insulation, good processing performance, and degradability. [0003] Polyurethane adhesive is an important part of the rapidly developing polyurethane resin. It has excellent performance and has been widely used in many aspects. It is one of the important varieties among the eight ...
