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.

Example Embodiment

[0025] Embodiment 1: Select 35% of sepiolite (Mg4Si6O15(OH)2 6H2O), 30% of expanded perlite (a mixture of SiO2, CaO, Al2O3, Na2O, Fe2O3, K2O, etc.), fumed silica (SiO2 ) 25%, inorganic powder hygroscopic agent 10%, appropriate amount of chemical stabilizer, 10% of the total material weight of water-soluble refractory adhesive is stirred and mixed, and the material in the formula, expanded perlite, plays a very good role in The basic filling and supporting function, the fumed silica monomer is fine, and has a good compacting effect. In addition, the curing of the water-soluble adhesive and the effect of the mold pressure strengthen the structural force of the core material. Interaction between sepiolite and hygroscopic agent quickly absorbs water, hardens and sets shape, and has excellent plasticity.
[0026] Embodiment two: select sepiolite (chemical composition is Mg4Si6O15(OH)2.6H2O belongs to the layered structure silicate mineral of orthorhombic (orthorhombic) crystal system) 35%, expanded perlite (SiO2, CaO, Al2O3 , Na2O, Fe2O3, K2O, etc.) 30%, inorganic foam cement (dry mortar method) 25%, inorganic powder hygroscopic agent 12%, chemical stabilizer amount, water-soluble refractory adhesive 10% of the total material weight for stirring Mixed, the formula material expanded perlite plays a good role in basic filling due to its large volume and light weight. Inorganic foam cement, diatom mud expansion, and vermiculite monomer are fine and have a good compacting effect. In addition, the water-soluble adhesive The effect of curing and mold pressure strengthens the structural strength of the core material, and then through the cross-action of high heat source drying and hygroscopic agent, sepiolite and hygroscopic agent quickly absorb water, harden and shape, and quickly obtain a green body that can be manufactured in an intelligent industry.
[0027] The ratio and size of the materials mentioned above can be properly adjusted according to the needs of different product thermal barrier values.
[0028] The core material used in the present invention includes any other inorganic substance powder, fiber body or organic substance powder or fiber body that does not release oxygen molecules (o2) and water molecules (H2O) after treatment.
[0029] The above two embodiments should be instant batching, mixing, injection, molding and high heat source setting, and can also be natural drying setting.
