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 heat protector mounted on a vehicle comprising;

a glass fiber having a plate shape and coated with aerogel; and

a plurality of thin films respectively bonded to both surfaces of the glass fiber,

wherein the thin films have a larger area than the glass fiber and extend from edges of the glass fiber, and

wherein the extended parts of the thin films are overlapped and folded to form a winding portion that seals the glass fiber.

2. The heat protector of claim 1, wherein the glass fiber is stacked in multiple layers.

3. The heat protector of claim 2, wherein the thin films are formed of aluminum to have a thickness of about 30 μ

m to 100 μ

m.

4. A method for mounting the heat protector of claim 3, the method comprising:

mounting a ring-shaped clamp on the exhaust pipe to mount the heat protector to cover an exterior of the exhaust pipe and protrude from a surface of the exhaust pipe; and

mounting the heat protector at the clamp to form a gap in a range of about 5 to 10 mm between the clamp and the exhaust pipe,

wherein the heat protector includes a flange at both ends in a longitudinal direction and is installed to cover a part of the exhaust pipe, and when the flange is mounted on a protrusion portion formed outwardly from the clamp, a fixing bolt binds the flange and the protrusion portion.

5. A method for mounting the heat protector of claim 3, the method comprising:

mounting the heat protector to cover an exterior of a cylindrical muffler;

bonding a fixing bracket to the muffler; and

inserting the heat protector into the muffler,

wherein the heat protector has a size that forms a gap in orange of about 5 to 10 mm between the heat protector and the muffler and has an opening part to which the muffler is introduced, and when the muffler is mounted on the heat protector, a fixing bolt is coupled to the fixing bracket extraneous to the heat protector to restrict movements of the heat protector.

6. 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.

7. The method for manufacturing a heat protector of claim 6, wherein the aerogel is prepared by mixing a highly heat-resistant binder containing a mixture of silicate and silicon is mixed with waterborne aerogel.

8. The method for manufacturing a heat protector of claim 7, wherein the waterborne aerogel s prepared by adding hydrophobic aerogel powder into an aqueous solution in which a super absorbent polymer (SAP) is mixed with water by stirring.

9. The method for manufacturing a heat protector of claim 8, further comprising:

stacking the aerogel that contains an adhesive and the multiple glass fibers coated with the aerogel.
