Problems solved by technology

[0002] Pressure vessels are often subject to changes in pressure due to changes in the volume of objects contained inside. When the pressure reaches a certain value or is at a high level for a long time, it is easy to cause the pressure vessel to crack. For example, the shell of the filter element body of the filter is prone to cracking in winter. Phenomenon, because when the ambient temperature is below zero, the freezing of water will cause volume expansion, squeeze the body shell with less shrinkage, and cause the shell of the filter element body to crack

Embodiment 1

[0027] At room temperature, 100g of thermoplastic elastomer is added to the mixer, and then a foaming agent with a mass fraction of 2% is added to the mixer to mix with the thermoplastic elastomer and stir evenly to form a micro-foamed thermoplastic elastomer material;

[0028] The uniformly stirred micro-foamed thermoplastic elastomer material is added to the printer for printing: the container body 1 is placed on the stage, and the stage can be rotated at a certain speed driven by the transmission component. The printing nozzle B extends into the container body 1 and cooperates with the rotation of the container body on the stage, and uses the mouth 31b of the extrusion head to print the micro-foamed thermoplastic elastomer material to the bottom wall 12 of the container body , so that the bottom wall micro-foamed elastomer layer is first formed on the bottom wall 12; then, the print nozzle B prints the side wall 11 of the pressure container, and the micro-foamed thermoplasti...

Embodiment 2

[0030] At room temperature, 100g of thermoplastic elastomer is added to the mixer, and then a foaming agent with a mass fraction of 3% is added to the mixer and mixed with the thermoplastic elastomer for uniform stirring to form a micro-foamed thermoplastic elastomer material;

[0031] The uniformly stirred micro-foamed thermoplastic elastomer material is added to the printer for printing: the container body 1 is placed on the stage, and the stage can be rotated at a certain speed driven by the transmission part. The printing nozzle B extends into the container body 1 and cooperates with the rotation of the container body on the stage, and uses the mouth 31b of the extrusion head to print the micro-foamed thermoplastic elastomer material to the bottom wall 12 of the container body , so that the bottom wall micro-foamed elastomer layer is first formed on the bottom wall 12; then, the print nozzle B prints the side wall 11 of the pressure container, and the micro-foamed thermopla...

Embodiment 3

[0033]At room temperature, 100g of thermoplastic elastomer is added to the mixer, and then a foaming agent with a mass fraction of 4% is added to the mixer and mixed with the thermoplastic elastomer for uniform stirring to form a micro-foamed thermoplastic elastomer material;

[0034] The uniformly stirred micro-foamed thermoplastic elastomer material is added to the printer for printing: the container body 1 is placed on the stage, and the stage can be rotated at a certain speed driven by the transmission part. The printing nozzle B extends into the container body 1 and cooperates with the rotation of the container body on the stage, and uses the mouth 31b of the extrusion head to print the micro-foamed thermoplastic elastomer material to the bottom wall 12 of the container body , so that the bottom wall micro-foamed elastomer layer is first formed on the bottom wall 12; then, the print nozzle B prints the side wall 11 of the pressure container, and the micro-foamed thermoplas...

Abstract

The invention discloses an anti-cracking pressure container and a preparation method thereof. The anti-cracking pressure container comprises a container body and a micro-foaming elastomer layer, the micro-foaming elastomer layer is directly attached to the inner wall of the container body; and the micro-foaming elastomer layer is a structure with a surface crust and bubbles filled inside. The micro-foaming elastomer layer is attached to the inner wall of the container body through 3D printing, and the micro-foaming elastomer layer can play a good buffering role when the pressure container is pressed, thereby offsetting volume expansion caused by water icing and ensuring normal use of products at low temperature. At the same time, the anti-cracking pressure container utilizes the 3D printing technology to attach the micro-foaming elastomer layer to the container body without developing of a mold, thus having higher efficiency and lower cost.

Description

technical field [0001] The present invention relates to a crack-resistant pressure vessel and a method for making the same. Background technique [0002] Pressure vessels are often subject to changes in pressure due to changes in the volume of objects contained inside. When the pressure reaches a certain value or is at a high level for a long time, it is easy to cause the pressure vessel to crack. For example, the shell of the filter element body of the filter is prone to cracking in winter. Phenomenon, because when the ambient temperature is below zero, the freezing of water will cause volume expansion, squeeze the body shell with less shrinkage, and cause the filter body shell to crack. Contents of the invention [0003] In order to solve the above technical problems, the object of the present invention is to provide a crack-resistant pressure vessel and a preparation method thereof. [0004] The present invention is achieved through the following technical solutions: a...
