Preparation process of three-dimensional simulation wood grain powder coating

Abstract

The invention relates to the technical field of three-dimensional simulation wood grain powder coatings, and discloses a preparation process of a three-dimensional simulation wood grain powder coating. The preparation process is completed by using spraying equipment for preparing the three-dimensional simulation wood grain powder coating. The spraying equipment for preparing the three-dimensional simulation wood grain powder coating comprises a shell, a transmission mechanism, a communicating mechanism, a pushing and brushing mechanism, a limiting mechanism, a triggering mechanism and a deformation mechanism, wherein the inner wall of the shell is movably connected with the transmission mechanism, and the inner side of the shell is fixedly connected with the communicating mechanism. According to the preparation process of the three-dimensional simulation wood grain powder coating, the communicating mechanism is driven by the transmission mechanism to move, so that a circuit is switched on, the three-dimensional simulation wood grain powder coating is prevented from being attached to the inner wall of a nozzle, the situation that after the spraying equipment is used, the three-dimensional simulation wood grain powder coating drips from the nozzle is prevented, mottles of dripping on a wood board are avoided, the outdoor decoration performance of the wood grain powder coating is improved, the three-dimensional layering sense of spraying of the three-dimensional simulation wood grain powder coating is improved, and the defect rate of products is reduced.

Description

Technical field [0001] The present invention relates to the field of three-dimensional stereoscopic grain powder coating, in particular a three-dimensional stereoscopic graft powder coating process. Background [0002] The three-dimensional stereoscopic wood graphic powder coating is made of a saturated polyester resin and an epoxy mixture, and a wooded wood product is sprayed with a wood grain, which has a beautifully elegant imitation wooden texture. Some spraying devices are turned on and closed by controlling the sprayed valves, thereby controlling the spraying of woodwood, causing a phenomenon in which the spraying equipment is used after use. [0003] Existing spraying equipment, due to the intermittent use of the spraying equipment, the process of intermittent switches caused by the spraying equipment, which causes the inner wall of the spout to adhere with a three-dimensional stereo wood grain powder, resulting in a spraying equipment, after use, The spout will appear dro...

Problems solved by technology

[0002] The three-dimensional simulated wood grain powder coating is made of saturated polyester resin and epoxy mixture as the base material. The wood products sprayed with wood grain powder have beautiful and elegant imitation wood texture. As far as the process of wood grain powder spraying is concerned, it is now Some spraying equipment control the opening and closing of the spraying valve, and then control the spraying of wood grain powder, which will cause dripping of the spraying equipment after use.

[0003] During the use of the existing spraying equipment, due to the intermittent use of the spraying equipment, the valve of the spraying equipment is intermittently switched on and off, which will cause a three-dimensional simulated wood grain powder coating to be attached to the inner wall of the nozzle, resulting in the spraying equipment being used. There will be dripping of three-dimensional simulation wood grain powder paint at the nozzle, which will cause dripping mottled on the wooden board, which will reduce the outdoor decoration of wood grain powder soil coating, resulting in poor three-dimensional layering of three-dimensional simulation wood grain powder paint spraying , improving the defect rate of the product
