Description

Technical Field

[0002] Nylon elastomer, also known as thermoplastic polyamide elastomer (TPAE), is a special polymer material, a type of block copolymer composed of a high-melting-point crystalline polyamide (nylon) hard segment and a non-crystalline polyether or polyester soft segment. Nylon elastomer processing requires the use of a supercritical foaming device, a device specifically designed to process nylon elastomer materials into foam structures using supercritical fluid foaming technology. The working principle of this device is based on the special physical properties of supercritical fluids. By precisely controlling the temperature, pressure, and fluid state, the nylon elastomer interacts with the supercritical fluid, thereby achieving the foaming process.

The overall device structure is simple, which is convenient for stirring and preventing adhesion and wall hanging, thereby efficiently promoting the full contact and mixing of polyurethane elastomer particles and supercritical fluid, and facilitating the filtering and purification of depressurized exhaust gas to avoid pollution of the processing environment. It has high stability and practicality and has certain promotion value.

[0004] The above patent has the following problems:

[0005] This patent has some shortcomings when used. For example, the supercritical foaming device cannot quantitatively add materials during use, resulting in the added materials not being able to maintain the appropriate ratio, affecting the quality of the processed product. In addition, although the supercritical foaming device facilitates stirring to prevent adhesion and wall adhesion, the spiral screw has a limited stirring range, and the stirring efficiency of materials far away from the spiral screw is low. In view of this, we propose a supercritical foaming device for nylon elastomers. Utility Model Content
