Problems solved by technology

However, the water-based acrylic paints on the market are often hot, sticky and brittle. In the dry environment below 0°C for a long time in northern my country, it is easy to crack, and the paint needs to play a certain role in heat preservation. In the warm and humid southern my country In the environment, water vapor, rainwater, etc. are easy to penetrate into the wall and corrode the wall, which not only affects the aesthetics of the building, but also reduces the service life of the building

Abstract

The invention discloses a spraying instrument special for a waterproof heat-preservation outer wall coating. The spraying instrument comprises a cart and a taking and placing device, wherein one side, close to a first threaded rod, of the cart is connected with a first guide rod, and the taking and placing device is fixed on one side of a binding device. According to the spraying instrument special for the waterproof heat preservation outer wall coating, a spraying device is arranged, the coating in a three-way pipe enters a hose through a conveying pipe, then enters a spraying head at one end through the hose and is sprayed out through a mist spraying opening in one side of the spraying head, a third threaded rod is rotated, the third threaded rod drives the spraying head to move in the direction of a second guide rod, the spraying head moves to extrude sealing gaskets on the two sides, pressure borne by the sealing gaskets is transmitted to a stopping block, the stopping block is stressed to extrude a third spring to enter a groove, the number of spraying nozzles blocked by the sealing gaskets is smaller and smaller, the number of spraying nozzles capable of being sprayed is larger and larger, the spraying area is increased due to the increase of the number of the spraying nozzles, and the spraying area is convenient to control.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a spraying device specially used for waterproof and thermal insulation exterior wall coatings. Background technique [0002] Architectural exterior wall coatings are coatings that are applied to the entire exterior wall of a building. Its main function is to decorate and protect the exterior wall, making the building look flat and beautiful, and at the same time protecting the building. Exterior wall paint needs to be exposed to the outdoor environment. Compared with interior wall paint, it faces a harsher environment, especially in some humid areas in the south, where the waterproof function of exterior wall paint is more demanding. [0003] The spraying of architectural exterior wall paint is to use a spray gun or a disc atomizer to disperse into uniform and fine mist droplets by means of pressure or centrifugal force. The coating method applied to the surface of the objec...
