A water-based polyurethane matting resin grinding device

Abstract

The invention provides a water-based polyurethane matting resin grinding device, comprising a base, a vibrating assembly is arranged on the base, a collecting box is installed on the vibrating assembly; a grinding part is arranged above the collecting box; the grinding part includes a sealing plate, Grinding head and grinding groove; the top surface of the grinding head is connected with a connecting shaft, and the top of the connecting shaft passes through the sealing plate and is located above the sealing plate; the grinding groove is an arc-shaped groove made of a mesh plate; the grinding end of the grinding head The surface shape matches the inner side of the grinding tank; the opening end of the grinding tank is connected to the inner side of the collection box; a flexible curtain is installed under the sealing plate, and the inner side of the flexible curtain is attached to the outer side of the collection box. Using the grinding device to grind resin can effectively reduce the phenomenon of excessive grinding or insufficient grinding of raw materials, improve the qualified rate of raw materials after grinding, and increase the utilization rate of raw materials; in addition, during use, it can avoid dust pollution to the environment and reduce Raw material loss.

Description

Technical field [0001] The present invention relates to the technical field of resin grinding equipment, specifically to a waterborne polyurethane matting resin grinding device. Background [0002] Grinding equipment is a kind of general equipment for grinding materials to make their particle size meet production needs or use needs, and is widely used in chemicals, materials and other fields. Waterborne polyurethane matting resin is a common resin material in the chemical industry, after use, it can form a low-gloss coating on the surface of the substrate, improve the appearance quality of the coating, and then improve the grade of the product. The particle size of the waterborne polyurethane matting resin has a great influence on the uniformity and matting of the coating, so it is usually necessary to grind the resin before use, and improve the uniformity and matting of the coating by improving the uniformity of the resin particles. [0003] At present, when using grinding equip...

AI Technical Summary

Problems solved by technology

[0003] At present, when using grinding equipment to grind water-based polyurethane matting resin, it is usually ground first, and then the ground resin is sieved, and then sieved multiple times to obtain a product that meets the demand. This resin treatment method mainly has the following problems: 1. It is because the equipment cannot control the degree of grinding of raw materials during the grinding process, and it is prone to insufficient grinding (more large particles in the product) or excessive grinding. The occurrence of these two phenomena seriously affects the grinding efficiency and the pass rate of the resin after grinding. ; Second, solid raw materials will inevitably generate dust during the grinding process, and a large amount of dust overflow will not only affect the working environment, but also cause inevitable losses to raw materials
