Core material in vacuum insulation chamber/bag and manufacturing process thereof

Abstract

The invention provides a core material in a vacuum insulation chamber / bag and a manufacturing process thereof, which belongs to the fields of vacuum insulation and isolation energy conservation. A fillable blank of the core material is prepared from main materials consisting of an inorganic meerschaum substance, an inorganic perlite substance, inorganic silica, inorganic expanded vermiculite, foamed cement and the like, a thermosetting fireproof adhesive (such as an adhesive with hydrolysis properties), a hygroscopic agent (such as inorganic powder) and a degasifer (e.g., an evapotranspiration type degasifer with zirconium as a main body and a non-evapotranspiration or compound type degasifer with barium, strontium, magnesium and calcium as main materials) through instant batching, mixing, casting, compression molding and high-energy heat-source shaping. According to the invention, the procedures of predrying and wrapping in conventional manufacturing processes for vacuum insulation boards are omitted, and the manufactured core material has the advantages of strong structural capacity, a lasting and stable vacuum degree, capacity of satisfying high requirements on energy conservation, small dimensional tolerance, simple operation, low cost, abundant resources, a wide scope of selected raw materials, light weight and a high grade of combustion performance.

Description

technical field [0001] The invention relates to the field of high heat barrier and energy saving, specifically a formula and a manufacturing method of a skeleton material in a vacuum cavity / bag of a vacuum heat insulation decorative panel. Background technique [0002] It can be seen from the domestic and foreign market use and sales and related documents that the core materials in the vacuum chamber of the vacuum insulation panel include sio2 airgel, glass fiber cotton, silica sio2 (powder, powder, ash, etc.), perlite, Inorganic materials such as rock wool, diatomaceous earth, volcanic ash, aluminum silicate fiber, natural clay, slag, wollastonite, bentonite, foam cement, expanded vermiculite, pumice, plant fiber, synthetic resin fiber, foam After pre-drying and molding, wrapping and shaping, and then putting them into a vacuum cavity / bag with barrier properties for vacuum sealing treatment, the core material of the high barrier cavity / bag disclosed before the date of appli...

[0002] It can be seen from the domestic and foreign market use and sales and related documents that the core materials in the vacuum chamber of the vacuum insulation panel include sio2 airgel, glass fiber cotton, silica sio2 (powder, powder, ash, etc.), perlite, Inorganic materials such as rock wool, diatomaceous earth, volcanic ash, aluminum silicate fiber, natural clay, slag, wollastonite, bentonite, foam cement, expanded vermiculite, pumice, plant fiber, synthetic resin fiber, foam After pre-drying and molding, wrapping and shaping, and then putting them into a vacuum cavity / bag with barrier properties for vacuum sealing treatment, the core material of the high barrier cavity / bag disclosed before the date of application is easy to seal after a long time. Relaxation, the thermal resistance gradually becomes lower, and the energy-saving effect is greatly reduced after a certain period of time. If the core material is not wrapped in the production process, its overall structural strength is poor, and it cannot be directly filled into the vacuum chamber / bag, and it cannot meet the requirements of intelligent production. To some extent, it also limits the scope of material selection
