Description

Technical Field

[0001] The utility model belongs to the technical field of waterproof coating spraying, in particular to a spraying machine for quick-setting waterproof coating. Background Art

[0002] Quick-setting waterproof coating is a kind of coating that adopts special process to prepare ultra-fine, suspended, micro-emulsified modified anionic emulsified asphalt and synthetic high molecular polymer (component A), and then mixes and reacts with special curing agent (component B) to produce a kind of excellent waterproof, anti-seepage, anti-corrosion and protective coating. In short, the main components of spray-on quick-setting rubber asphalt waterproof material are composed of more than two kinds of high-performance modified emulsified rubber asphalt and chemical coagulation catalyst. It is a two-component system with rapid initial coagulation characteristics. During the spraying process of the coating, the corresponding sprayer needs to be used for spraying, but it still has the following disadvantages in actual use:

[0003] 1. During the spraying process of the quick-setting waterproof coating sprayer, the corresponding equipment is directly output. During the output process, the output ratio is directly controlled by the valve. During the control, the accuracy of the valve control is not high enough, which may easily cause the proportion control to be incorrect when the components are output, affecting the waterproof effect after spraying;

[0004] 2. During the spraying process of the quick-setting waterproof coating sprayer, the coating needs to be mixed and then output through the nozzle. When the valves are closed after the spraying is completed, a small amount of waterproof coating will still remain in the nozzle. After solidification, it will cause the nozzle to be blocked. It needs to be cleaned in time after spraying. It needs to be disassembled for cleaning, which is inconvenient to use. Utility Model Content
