Problems solved by technology

[0003] Brushing waterproof coating on the fabric is one of the common coating processes, but the waterproof coating formed by brushing the surface of the fabric through the existing coating process will deteriorate the waterproof performance of the damaged part after local damage occurs , and if the damaged part is not repaired in time, as time goes by, the area of ​​the damaged part will further expand, resulting in worse and worse waterproof effect of the fabric

Embodiment 1

[0045] see Figure 1-4 , a coating process for a self-spraying nanometer waterproof coating, comprising the following steps:

[0046] S1. Brushing the bottom waterproof layer: place the fabric flat, and paint a layer of waterproof paint on the surface of the fabric as the bottom waterproof layer;

[0047] S2. Embedding repair balls: Before the bottom waterproof layer is solidified, power on the electromagnetic board, so that multiple spray repair balls 001 are evenly arranged on the bottom of the electromagnetic board under the action of magnetic attraction, and press down on the electromagnetic board to spray materials The repair ball 001 is embedded in the bottom waterproof layer;

[0048] S3. Spraying nanoparticles: After the bottom waterproof layer is solidified and formed, change the direction of the current to reverse the polarity of the electromagnetic plate, and under the action of magnetic repulsion, make the spray repair ball 001 spray hydrophobic nanoparticles 204 ...

Abstract

The invention discloses a coating process of a self-eruption type nano waterproof coating, and belongs to the technical field of coating process. The coating process of the self-eruption type nano waterproof coating is creatively provided with an eruption repairing ball, in the coating process, under an action of magnetic repulsive force between an electromagnetic plate and a linkage magnet, an elastic ball bag can be extruded to spray out hydrophobic nanoparticles, and the hydrophobic nanoparticles are sprayed out; therefore, a layer of the hydrophobic nanoparticles is automatically laid between a surface waterproof layer and a bottom waterproof layer, waterproof performance of the waterproof layers can be remarkably improved, when the surface waterproof layer is locally damaged, the linkage magnet can drive a material pressing piston plate and a flexible rubber sheet to move upwards and extrude waterproof paint under driving of elastic force of the elastic ball bag, so that the waterproof coating flows out from the top end of a material guide pipe and flows to a damaged part of the waterproof layer along the surface of the top end of a sealing cover plate to fill and repair the damaged part, so that the damaged part can be repaired in time, the waterproof performance of the fabric is guaranteed, and the damaged part can be effectively prevented from being further expanded.

Description

technical field [0001] The invention relates to the technical field of coating technology, in particular to a coating technology of a self-spraying nanometer waterproof coating. Background technique [0002] Coating is a method of coating paste polymers, molten polymers or polymer melts on paper, cloth, and plastic films to prepare composite materials (films) for the purposes of anti-corrosion, insulation, and decoration. [0003] Brushing waterproof coating on the fabric is one of the common coating processes, but the waterproof coating formed by brushing the surface of the fabric through the existing coating process will deteriorate the waterproof performance of the damaged part after local damage occurs , and if the damaged part is not repaired in time, the area of ​​the damaged part will further expand as time goes by, resulting in worse and worse waterproof effect of the fabric. Therefore, we propose a coating process of a self-spraying nano-waterproof coating. Conte...
