A kind of preparation method of chloroprene rubber asphalt waterproof coating

Abstract

The invention relates to a method for preparing neoprene asphalt waterproof coating, which uses asphalt cutting equipment, and the asphalt cutting equipment includes a cutting cylinder, a uniform feeding device and a pelletizing and discharging device, and the inner wall of the lower end of the cutting cylinder is provided with a There is a uniform feeding device, and a pelletizing and unloading device is arranged on the inner wall of the upper end of the cutting cylinder; the invention carries out feeding by uniformly and intermittently rotating the feeding cylinder, so that the asphalt blocks are evenly distributed on the upper inner wall of the unloading circular plate, solving the problem of greening When the block is loaded, it is often deposited at the feeding position, making the asphalt block piled up too high, causing the cutting knife to be difficult to feed, and affecting the cutting efficiency of the asphalt block; The cutting efficiency of asphalt blocks solves the problem that some asphalt blocks cannot be decomposed and unloaded because they slide to one side when they are cut.

Description

Technical field [0001] The present invention relates to the technical field of waterproof coating production, in particular to a neoprene asphalt waterproof coating preparation method. Background [0002] Neoprene asphalt waterproof coating is a new type of asphalt waterproof coating. Neoprene asphalt waterproof coating changes the traditional asphalt low temperature brittle cracking, high temperature flow characteristics, after modification, not only has the elasticity of neoprene rubber, strong adhesion, aging resistance, waterproof and anti-corrosion advantages, while the collection of asphalt waterproof performance, combined into high strength, fast film formation, waterproof strong, resistant to aging, elastic resistance to grass-roots deformation ability, cold work construction is convenient, do not pollute the environment of a high-quality waterproof coating. [0003] The production of neoprene asphalt waterproof coatings often need to be rubber and asphalt fine grinding p...

AI Technical Summary

Problems solved by technology

[0003] When producing neoprene asphalt waterproof coatings, it is often necessary to mix rubber and asphalt after fine grinding. The following problems often exist in the process of preliminary chopping of asphalt blocks: 1. When asphalt blocks are fed, they often deposit on the The location of the asphalt block makes the accumulation of asphalt block too high, which makes it difficult for the cutter to feed, which affects the cutting efficiency of the asphalt block; 2. When the asphalt block is decomposed, it often slides to one side when the cutter touches, causing some asphalt block The problem of being unable to be decomposed and unloaded
