Embodiment 1

[0050] Such as figure 1 and Figure 4 As shown, the method for suppressing the coating shrinkage of the water-based filler includes a sudden heat output, and the water-based filler comprising an amine curing agent, a water-based epoxy resin and a pigment is passed through the necking-shaped pipe 1 at a temperature of 85°; gradually cooled output, The water-based filler that has been output by sudden heating is passed through multiple necked pipes 1 in a staged cooling manner in the range of 50°-5°, that is, in the gradual cooling output, the temperature environment for the first time is 50°, and the final output of the filler is The ambient temperature is 5°, the decreasing temperature is 5° every time, and the ambient temperature of the filler passing through the pipe 1 is 50°, 45°, 40°, 35°, 30°, 25°, 20°, 15°, 10°, 5°; dense pressurization, continuously apply a pressure of 6MPa to the water-based filler in a closed environment through the pressurization equipment, and the ...

Embodiment 2

[0067] Such as figure 2 and image 3 As shown, the difference between the present embodiment and the first embodiment is that the pipe tool 1 is straight, and the extrusion efficiency of the water-based filler is high when the pipe tool 1 is straight.

[0068] The detailed structures, specific component sizes and principles not mentioned in this application document are all existing common knowledge or can be obtained by those skilled in the art through simple selection, and will not be repeated.

Abstract

The invention provides a method for inhibiting the coating shrinkage rate of a water-based filler, and a pipe tool, and belongs to the field of fillers. The method comprises the following steps: performing shock heating output: enabling the water-based filler to pass through a necking-down pipe tool at the temperature of 80-100 DEG C; carrying out gradual cooling outputting: enabling the water-based filler subjected to shock heating output to pass through a plurality of necking-down pipes in a range staged cooling manner; pressurizing and compacting: continuously applying pressure of 5 MPa orabove to the water-based filler in a closed environment through pressurizing equipment for 1 min or above; and carrying out pressure relief and rewarming: relieving the pressure of the pressurized water-based filler, and then rewarming to 20-30 DEG C. According to the method, colloid molecular clearances and characteristics are changed to a great extent, and the shrinkage rate of the water-based filler after the external pressure and temperature are changed is reduced. One end of the pipe tool is an input end, the other end of the pipe tool is an output end, the pipe tool is provided with a necking section, the port of the necking section is a port of the output end, and the pipe tool is further provided with an acting section. The pipe tool solves the problems of low efficiency, poor effect and the like of the existing method for processing the filler by adopting molecular intercalation and chain insertion reaction.

Description

technical field [0001] The invention belongs to the field of fillers, and relates to a method and a pipe for suppressing the coating shrinkage of water-based fillers. Background technique [0002] In the field of decoration, beautifying agent is a common material used to improve the overall aesthetics of tiles, and beautifying agent shrinkage and collapse are common problems. There are two main reasons. One is that the construction personnel are perfecting the grout Immediately after the seam is pressed, the beautifying agent is not pressed into the seam, and finally the beautifying agent shrinks and sinks due to the air in the seam, which is caused by the lack of technical quality of the construction personnel; the second is the current beautifying agent glue The plastid has a large molecular gap, and is prone to shrinkage due to changes in external temperature and pressure. [0003] For example, the application number is 2017100019923, the application date is 2017.1.3, an...
