preparation example Construction

[0038] The invention proposes a method for preparing fireproof cloth, preparing hollow glass microspheres loaded with black titanium dioxide and hafnium oxide; Fiber; then use fireproof fiber to weave into fireproof cloth. The weaving method of using fireproof fibers to weave fireproof cloth can be pure spinning or blending.

[0039] Specifically, the preparation of hollow glass microspheres loaded with black titanium dioxide and hafnium oxide includes the following steps:

[0040] Step S1, preparing hollow glass microspheres loaded with black titanium dioxide;

[0041] Step S2, using direct chemical deposition to deposit hafnium oxide on the hollow glass microspheres loaded with black titanium dioxide, thereby forming hollow glass microspheres loaded with black titanium dioxide and hafnium oxide.

[0042] Here, the hollow glass microspheres are not only used as the carrier of black titanium dioxide and hafnium oxide, but also used to provide higher emissivity; while the haf...

no. 1 example

[0072] Mix 0.2 mol / L tetrabutyl titanate ethanol solution with hollow glass microspheres with a density of 0.5 g / mL to form a suspension; the mass fraction of the hollow glass microspheres in the suspension is 1 wt%. Then, the dispersant of model SIM6492.72, accounting for 0.1 wt% of the mass fraction of the suspension, was slowly added dropwise into the suspension; the time for adding the dispersant was controlled to 0.5h through the dropping funnel.

[0073] Add the suspension after dropping the dispersant into the hydrothermal kettle, place the hydrothermal kettle in an oven for stage heating to obtain the first solid substance; wherein, the stage heating program is heating at 150°C for 2 hours, and heating at 180°C Heating for 5h and heating at 220°C for 3h. After the staged heating reaction is completed, the first solid matter is filtered and dried overnight in an oven at 100° C. to obtain hollow glass microspheres loaded with ordinary titanium dioxide.

[0080] Mix 0.3 mol / L titanium tetrahydrofuran isopropoxide solution with hollow glass microspheres with a density of 1.0 g / mL to form a suspension; the mass fraction of the hollow glass microspheres in the suspension is 2 wt%. Then, the dispersant of model SIB1824.82, accounting for 0.3 wt% of the mass fraction of the suspension, was slowly added dropwise into the suspension; the time for adding the dispersant was controlled to 0.8h through the dropping funnel.

[0081] Add the suspension after dropping the dispersant into the hydrothermal kettle, place the hydrothermal kettle in an oven for stage heating to obtain the first solid substance; wherein, the stage heating program is heating at 150°C for 3 hours, heating at 180°C Heating for 6h and heating at 220°C for 4h. After the staged heating reaction is completed, the first solid matter is filtered and dried overnight in an oven at 100° C. to obtain hollow glass microspheres loaded with ordinary titanium dioxide.

Abstract

A fireproof cloth and a preparation method thereof; the preparation method of the fireproof cloth comprises the following steps: preparing hollow glass microspheres loaded with black titanium dioxide and hafnium oxide; and then finishing the hollow glass microspheres loaded with black titanium dioxide and hafnium oxide On the fiber, so as to make fireproof fiber; then use fireproof fiber to weave into fireproof cloth. The fireproof cloth and the preparation method thereof of the present invention are novel in design and strong in practicability.

Description

technical field [0001] The invention relates to the field of fabrics, in particular to a fireproof cloth and a preparation method thereof; specifically, the present invention provides a fireproof cloth with passive radiation refrigeration, sterilization and deodorization, and heat insulation; the fireproof cloth is made of black titanium dioxide loaded , hafnium oxide and hollow glass microsphere fibers, which can effectively prevent ignition, high temperature resistance, corrosion resistance and deodorization, and can be used for emergency rescue and disaster relief in places with large flames. Background technique [0002] With the development of science and technology, people have higher and higher requirements for the quality of life; because cloth is widely used in clothing, fire protection, decoration and other industries, people also put forward higher requirements for the functionality of cloth. . Fireproof cloth is a kind of functional fabric, which can be used in ...
