Abstract

A heat protector mounted on a vehicle is provided. The heat protected includes a glass fiber that has a plate shape and includes aerogel immersed therein. Thin films are respectively bonded to both surfaces of the glass fiber, and the thin films have a larger area than the glass fiber and extend from edges of the glass fiber. The extended parts of the thin films are overlapped and folded to form a winding portion that seals the glass fiber.

Claims

1. A method for manufacturing a heat protector comprising:

cutting a glass fiber into a plate-shaped piece having a substantially uniform size;

coating aerogel on both surfaces of the glass fiber;

drying the glass fiber coated with the aerogel;

respectively stacking thin films having a larger area than the glass fiber on an upper surface and a lower surface of the glass fiber coated with the aerogel;

pressurizing the glass fiber and the thin films to adhere to each other; and

forming a winding portion by folding a plurality of parts of the thin films that protrude from the glass fiber.

2. The method for manufacturing a heat protector of claim 1, wherein the aerogel is prepared by mixing a highly heat-resistant binder containing a mixture of silicate and silicon with waterborne aerogel.

3. The method for manufacturing a heat protector of claim 2, wherein the waterborne aerogel is prepared by adding hydrophobic aerogel powder into an aqueous solution in which a super absorbent polymer (SAP) is mixed with water by stirring.

4. The method for manufacturing a heat protector of claim 3, further comprising:

stacking the glass fiber coated with the aerogel that contains the highly heat-resistant binder in multiple layers.
