Flameproof material for wearables, personal protective equipment, lithium-ion battery flame protection, and general flame protection
Flameproof material for wearables, personal protective equipment, lithium-ion battery flame protection, and general flame protection are disclosed. A particular embodiment includes a flameproof material comprising: a first material being a combination of Oxidized Polyacrylonitrile (PAN) fiber and Para-aromatic polyamide (P-aramid) fiber; a second material being a combination of Oxidized PAN fiber, fire-resistant rayon (FR-rayon), and P-aramid fiber; and a third material being a combination of silica aerogel and fibrous glass configured for bonding with the first or second materials, the second material being configured for bonding with the first or third materials.
1 . A flameproof material comprising:
a first material being a combination of Oxidized Polyacrylonitrile (PAN) fiber and Para-aromatic polyamide (P-aramid) fiber:
a second material being a combination of Oxidized PAN fiber, fire-resistant rayon (FR-rayon), and P-aramid fiber; and
a third material being a combination of silica aerogel and fibrous glass configured for bonding with the first or second materials, the second material being configured for bonding with the first or third materials,
the flameproof material having a laminate structure comprising, in order from a flame-facing side to a second side: (i) a first fabric layer comprising the first material; (ii) an intermediate third layer consisting essentially of a silica aerogel and a fibrous glass; and (iii) a second fabric layer comprising the second material; wherein the third layer is bonded to the first and second fabric layers.
2 . The flameproof material of claim 1 further including a fourth layer comprising a fourth material being a combination of Oxidized PAN fiber and P-aramid fiber in a composition different from the first material, the fourth material configured for bonding with the first, second, or third materials and disposed proximate the second fabric layer.
3 . The flameproof material of claim 2 further including a fifth material being a moisture-wicking fiber, the fifth material configured for bonding with the fourth or third materials.
4 . The flameproof material of claim 1 wherein the third material includes iron oxide and aluminum trihydrate and comprises at least 30% amorphous silica and at least 40% fibrous glass by weight.
5 . The flameproof material of claim 1 wherein the first material includes at least 50% Oxidized PAN fiber.
6 . The flameproof material of claim 1 wherein the first material includes at least 15% P-aramid fiber.
7 . The flameproof material of claim 1 wherein the second material includes at least 20% FR-rayon.
8 . The flameproof material of claim 1 wherein the third material includes at least 30% amorphous silica and at least 40% fibrous glass and has a thickness of between 5 mm and 10 mm.
9 . The flameproof material of claim 3 wherein the moisture-wicking fiber is cotton.
10 . The flameproof material of claim 1 wherein the second material is configured for bonding with the first material using an adhesive.
