Problems solved by technology

However, because the paint is painted on site, the thickness of the coating is limited, and each layer needs to be completely dry before the next painting can be carried out. In this way, it often takes a long time to achieve the required thickness.

[0019] The spraying method according to the invention comprises firstly preparing the first component A and the second component B of the paint. The first component A includes superfine suspension microemulsion type modified emulsified asphalt. Asphalt materials are insoluble in water and do not mix with water, but through high-speed agitation or shearing, the asphalt is broken into tiny particles and dispersed in an aqueous solution of surface active substances with emulsifiers to obtain a uniformly dispersed colloid. The basic function of emulsifiers is to reduce surface tension. It is characterized by a water-soluble (hydrophilic) polar group and an oil-soluble (hydrophobic) non-polar group in the molecule. In the asphalt-water system, the emulsifier molecules move between the asphalt and the water interface, and the hydrophobic groups of the molecules are adsorbed on the surface of the asphalt and charged, while the hydrophilic groups enter the water phase. This links th...

[0025] figure 2 It is a structural schematic diagram of the spraying equipment according to the second embodiment of the present invention. The spraying equipment includes an engine 1 , a transmission 2 , a first pump 3 , a second pump 4 , a first container 5 , a second container 6 , a first spray gun 7 and a second spray gun 8 . The engine 1 can be a gasoline engine, a diesel engine or an electric motor to generate power to drive the first pump 3 and the second pump 4 . The transmission device 2 transmits the power of the engine 1 to the first pump 3 and the second pump 4 respectively. The transmission device 2 can adopt various transmission modes. For example, the transmission device 2 can be composed of a power output device on the engine 1 such as a driving wheel, a power input device of the first pump 3 and the second pump 4 such as a driven wheel, and two belts connecting the driving wheel and the two driven wheels respectively . The transmission device 2 can also a...

[0031] Figure 4 It is a structural schematic diagram of the spraying equipment according to the third embodiment of the present invention. The difference between the spraying equipment of the third embodiment and the second embodiment is that, in addition to being connected with the first spray gun 7 and the second spray gun 8, the first pump 3 and the second pump 4 are also connected with the third spray gun 19 and the fourth spray gun. Spray guns 20 are connected. That is, the first pump 3 and the second pump 4 are respectively connected with two spray guns. Similar to the first spray gun 7 and the second spray gun 8, the third spray gun 19 and the fourth spray gun 20 can also be fixed on a base with a predetermined angle formed therebetween. Since the number of spray guns of the spraying equipment according to the third embodiment of the present invention is increased, the efficiency of the spraying equipment is increased. According to specific conditions, the spraying ...

Abstract

The invention discloses a spraying method and spraying equipment for a two-component coating. The spraying method comprises the following steps: a first component and a second component of the coating are prepared, wherein the first component comprises modified emulsified asphalt, and the second component comprises a water solution of calcium chloride; the first component and the second componentare respectively placed into a first container and a second container; an engine is started, a first pump and a second pump are simultaneously driven by a rotation device; the first component inside the first container is absorbed into a first pipeline by the first pump and delivered to a first spray gun through a third pipeline; and the second component inside the second container is absorbed into a second pipeline by the second pump and delivered to a second spray gun through a fourth pipeline. When the two-component coating is sprayed, a gunlock of the first spray gun and a gunlock of the second spray gun are simultaneously pulled so that the first component and the second component are respectively sprayed out of the first spray gun and the second spray gun and then converged and instantly reacted and fallen on a substance to be sprayed to form a film layer. The method combines the advantages of coiled (sheet) materials and coatings.

Description

technical field [0001] The invention relates to a spraying method and spraying equipment of a two-component paint, in particular to a spraying method of a two-component paint and the spraying equipment with a double-pipe spray gun used therein. Background technique [0002] In the field of protective materials such as waterproofing and anticorrosion, the traditional and current products on the market can be divided into two categories: roll (sheet) materials and coatings. The main advantage of roll (sheet) material is that the product is prefabricated in the factory and can be reinforced or thickened according to requirements to meet specific requirements. But precisely because these products are prefabricated in factories, they lack flexibility in on-site construction, especially when dealing with special-shaped objects. Although the industry has researched and developed many physical and chemical reinforcement methods, reinforcement processes and auxiliary materials, the ...
