Abstract

The invention relates to a method for forming a waterproof coating in a negative pressure environment, and belongs to the technical field of spraying equipment. The method comprises the following steps: step 1, stirring the coating, namely, stirring the coating in a storing tank; and step 2, coating under negative pressure, namely, starting a vacuum pump to create the negative pressure environment for a negative pressure space, and coating the coating on a test part through a spraying mechanism. According to the technical scheme, the method has the advantages that the coating is stored in the storing tank and is stirred all the time so as to ensure uniform mixing; the vacuum pump can provide the negative pressure state to the negative pressure space, so that the escape speed of bubbles in a coating layer on the surface of the test part is increased, and as a result, the deflect of bubbles in the coating can be reduced. The method is beneficial in technological effect and obvious in practical value.

Description

technical field [0001] The invention relates to a molding method of a waterproof coating in a negative pressure environment, and belongs to the technical field of spraying equipment. Background technique [0002] Spraying is a coating method that is dispersed into uniform and fine droplets by means of pressure or centrifugal force through a spray gun or disc atomizer and applied to the surface of the object to be coated. It can be divided into air spraying, airless spraying, electrostatic spraying and various derivatives of the above-mentioned basic spraying forms, such as high-flow and low-pressure atomizing spraying, thermal spraying, automatic spraying, multi-group spraying, etc. In the prior art, in order to improve the uniformity of coating thickness, mechanical spraying is generally used. However, whether it is mechanical spraying or manual spraying, defects such as bubbles are prone to occur. For example, when the waterproof coating is sprayed on the molded specimen...
