Abstract

The invention discloses an attapulgite nanorod crystal bundle modified glass fiber core material and a preparation method thereof. The core material adopts glass fiber as a matrix, and the mass fraction of the glass fiber is 70-80%. 15%-25% of attapulgite nanorod crystal bundles prepared by adopting a pressure-regulating homogeneous dissociation process and 5% of a binder are doped in pores of the glass fiber. According to the glass fiber core material disclosed by the invention, through nano-modification of the attapulgite nanorod crystal bundles, the excellent heat insulation performance of the attapulgite nanorod crystal bundles is fully played while the sensitivity of a vacuum heat insulation plate to air pressure is reduced, the service temperature of the vacuum heat insulation plate is increased, and a choice with high cost performance is provided for the field of building energy conservation.

Example Embodiment

[0022] Example 1
[0023] Refer figure 1 It is a concave-resistant solenoid core material, and 1 is glass fiber, and 2 is a bump of a concave-resistant solar terminus, characterized in that there is a binder, a fiberglass aperture between the core fibers. The metallic beam of doped resurorated soil, including 80% glass fibers, 15% iris soil nano-cod cell and 5% silicon oxide according to the mass percentage. The specific process in the preparation is as follows:
[0024] (1) Take the resilicle soil and ethanol in the deionized water, which is filtered to obtain a concavo roll soil suspension;
[0025] (2) The suspension obtained in step (1), the inositol hexamphrocyanic acid is fully stirred in deionized water, and then placed in a high pressure homogenizer, followed by freeze drying, solid grinding, 200 mesh screen filtered, Get a refractural barnini bar bar powder;
[0026] (3) Powder of the uneven tank in step (2), inositol hexaphilic acid, high-alkali glass fiber and silicon oxide, and then stirred in an acidic aqueous solution, then feed into a tissue tank, and add water to obtain unevenness. Rod nice cod crystal modified glass fiber dispersion;
[0027] (4) Send the dispersion obtained in step (3) into the mesh front box, using the molding network to dewatering it, forming a concave lipstone nano-based crystal modified glass fiber core material blank
[0028] (5) Rolling the core material obtained in step (4) with a pressure swim, then dry the water by negative pressure, the oven is dried, and the tailor is obtained according to the use requirements, that is, the uneven bar nano Crystramid-modified glass fiber core material.
[0029] The embossed solenoid cell-modified glass fiber core produced by the embodiment was increased by 50 ° C, and the air pressure sensitivity was lowered from 100 Pa to 150Pa to provide high cost options for building energy saving.
