Technical Field

[0001] The utility model relates to the technical field of polyurethane elastomer materials, in particular to a water absorption detection device for MDI system polyurethane elastomer materials. Background Art

[0002] Polyurethane elastic material is a highly emerging organic molecular material. It is widely used in many fields of the national economy because of its excellent comprehensive properties such as high strength, high toughness, wear resistance and oil resistance. In recent years, MDI system polyurethane elastomer materials have begun to be used.

[0003] The prior art (patent number: CN215492960U) discloses a device for detecting the water absorption of polyurethane elastomer materials of an MDI system, comprising a support platform fixedly connected to the ground, a water tank with an upper end opening fixedly connected to the support platform, a detection mechanism for detecting the water absorption of polyurethane elastomer materials is arranged at both the left and right ends of the water tank, an L-shaped plate is fixedly connected to the ground on the right side of the support platform, and a conveying mechanism for conveying raw materials into the detection mechanism is arranged on the L-shaped plate. The beneficial effect of the utility model is that by setting up the detection mechanism and the conveying mechanism, the water absorption of the material can be quickly detected, the difference in mass before and after the material absorbs water can be obtained by the difference between the first electronic scale and the second electronic scale, and since the density of water is constant, the volume of the material absorbed water can be obtained, thereby realizing the detection of the water absorption performance of the material.

Therefore, we propose a new type of water absorption detection device for MDI system polyurethane elastomer materials. Utility Model Content
