Embodiment Construction
[0028] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0029] Such as Figure 4 Shown, the preparation process of the present invention is as follows:
[0030] (1) Each weaving triangle has a side length of 375mm and is composed of five meshes, each mesh size is 75mm, with a total of three layers of the same structure;
[0031] (2) according to the size that the first step obtains, carry out the weaving of net;
[0032] (3) if figure 2 , 3 As shown, the heat insulation pad is composed of four woven regular triangles, one corner of the first woven triangle is connected with one corner of the second woven triangle to form a node a, one side of the first woven triangle and one side of the second woven triangle and the node a is on the same straight line 1, and other parts of the two triangles are on the same side of straight line 1. The two corners of the third triangle are respectively connected with ...

The invention relates to a three-dimensional grid heat-insulation pad on the basis of weaving technologies and a method for preparing the three-dimensional grid heat-insulation pad, and is mainly applied to designing and manufacturing light heat-insulation pads. The three-dimensional grid heat-insulation pad and the method have the advantages that as discovered by theoretic and qualitative analysis on existing configuration, triangular siepinski fractural structures can be light on the premise that the strength, the rigidity and the stability are guaranteed, the contact areas of the air and heat sources can be enlarged, and good heat-insulation effects can be realized; three edges of each triangle are processed by the aid of the weaving technologies during practical analysis, accordingly,design ideas of further saving materials by integral devices can be implemented, the heat-insulation efficiency can be enhanced, and the flexibility of structures can be improved; the thickness of thethree-dimensional grid heat-insulation pad can be enlarged owing to multilayer overlaying designs, and the excellent heat-insulation effects can be realized even if the areas of the bottom surfaces of heat-insulation objects are larger than those of the triangles.
Description
technical field [0001] The invention relates to a three-dimensional mesh heat insulation pad based on a weaving method and a preparation method, which can be used in the design and manufacture of heat insulation pads for dining tables and aviation. Background technique [0002] Heat insulation pad is an object that separates heat-generating objects and supports, thereby acting as a mat for heat insulation and protection of supports such as dining tables. Air is a poor conductor of heat, and its heat insulation effect is much better than that of solid wood, plastic, etc. 0.25W / m·k) However, heat insulation pads in daily life either only pursue beauty while ignoring its practicability, or only pursue practicability while ignoring its beauty. And the configuration design of the existing heat insulation pad is unreasonable, such as figure 1 As shown, the material is wasted and the heat insulation effect is not good. Contents of the invention [0003] The technical problem o...
