Embodiment 1

[0021] Disperse the modified porous diatomite in the high-temperature-resistant binder. After fully dispersing, apply the dispersion system on the nickel shell mold and heat to dry and solidify the high-temperature-resistant binder to obtain a heat insulation system. . Among them, the particle size of the modified porous diatomite is 100 mesh, and the porosity is 40%. The mass ratio of the modified porous diatomite to the high temperature resistant binder is 1:0.1. When painting, pay attention to using a brush with fine bristles to ensure that the surface of the heat insulation system is smooth and flat. The resulting thermal insulation system has a thickness of 2 mm. The temperature difference between the heat insulation system and the surrounding nickel shell mold remains at 29 degrees Celsius after repeated heating, and the Mohs hardness is greater than 6H, and the wear resistance meets the continuous production of 100 molds without any change in the surface of the heat i...

Embodiment 3

[0025] Disperse the porous magnesium saponite in the high-temperature-resistant binder. After fully dispersing, the dispersion system is coated on the nickel shell mold, heated, and the high-temperature-resistant binder is dried and solidified to form, and the heat insulation system can be obtained. When painting, pay attention to using a brush with fine bristles to ensure that the surface of the heat insulation system is smooth and flat. Among them, the particle size of the porous magnesium saponite is 80 mesh, and the porosity is 50%. The mass ratio of porous magnesium saponite to high temperature resistant binder is: 1:0.3. The resulting thermal insulation system has a thickness of 3 mm. The temperature difference between the heat insulation system and the surrounding nickel shell mold is maintained at 27 degrees Celsius after repeated heating, and the Mohs hardness is greater than 6H, and the wear resistance meets the continuous production of 100 molds without any change ...

Abstract

The invention provides a method for constructing heat insulating system. The method comprises the following steps: S1, providing a porous filler; S2, providing a high temperature resistant binder; S3, dispersing the porous filler in the high temperature resistant binder to form a dispersed system; S4, applying the dispersed system onto a mould; S5, heating the mould and solidifying the high temperature resistant binder to form the heat insulating system, wherein the particle size of the porous filler is not greater than 100 meshes, and the porosity is not less than 40 percent. The invention also provides the heat insulating system which is constructed by using the method. The heat insulating system is constructed on the surface of local area of the mould on which film formation is not needed, the idea of combining the porous structure with the high temperature resistant material is adopted to successfully construct the heat insulating system in the local area of the mould rationally and effectively, so that residual epidermis is not needed to be excavated and discarded after formation, raw materials are largely saved and production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of the automobile industry, and more particularly relates to a method for constructing a heat insulation system and the heat insulation system. Background technique [0002] In recent years, my country's automobile industry has developed rapidly. With the increase in demand and the improvement of user requirements, the production technology of automobile-related products is also constantly improving. Taking the slush molding process as an example, the products produced by this process have the characteristics of good hand feeling, good visual effect and less product process restrictions, and are widely used in the production of mid-to-high-end automotive interior parts. The raw materials required for the slush molding process are mainly PVC powder and TPU powder, among which PVC occupies a dominant position in the current slush molding products due to its low cost and good manufacturability. PVC powder for ...
