Crusher for producing waterborne polyurethane resin raw material

Abstract

The invention discloses a crusher for producing a waterborne polyurethane resin raw material. The crusher comprises a horizontal stable bottom plate, wherein the top of the horizontal stable bottom plate is fixedly connected with a crushing working box; the right side of the top of the horizontal stable bottom plate is fixedly connected with a vertical rod; the left side of the surface of the vertical rod is fixedly connected with a horizontal top plate; the middle of the bottom of the horizontal top plate is fixedly connected with a rotary motor box; the top of the inner wall of the rotary motor box is fixedly connected with a rotary motor through a motor base; and a thread clamping rod penetrates through one side of the surface of the crushing working box. The invention relates to the technical field of crushers. According to the crusher for producing the waterborne polyurethane resin raw material, disclosed by the invention, when the crusher is used for carrying out primary crushing, materials can be stably crushed at the top and the stability of the primary crushing is improved; and a swinging rod and a swinging handle are arranged so that a worker can conveniently swing an adjusting plate when the materials are subjected to secondary crushing, and furthermore, the materials at the top of the adjusting plate are released.

Description

technical field [0001] The invention relates to the technical field of crushers, in particular to a crusher used for the production of water-based polyurethane resin raw materials. Background technique [0002] At the end of the last century, with the strengthening of people's awareness of environmental protection and environmental protection laws and regulations, the research and development of environmentally friendly water-based polyurethane has been paid more and more attention. The market of type polyurethane represents the development direction of coatings and adhesives. Surprisingly, among water-based resins, water-based polyurethane is still a representative of excellent resins, and it is one of the hotspots of modern water-based resin research. Hydrophilic chain extender is a water-based functional monomer used in the preparation of water-based polyurethane, which can introduce hydrophilic groups into the main chain of water-based polyurethane macromolecules. The ...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a crusher for the production of water-based polyurethane resin raw materials, which solves the problem that ordinary crushers for the production of water-based polyurethane resin raw materials can only be crushed by an electric crushing device during normal operation. Raw materials are crushed once, the crushing is often not thorough enough, and the product qualification rate is low
