Embodiment 1

[0034] The molecular structure of phenolic resin prepolymer is:

[0035]

[0036] The phenolic resin prepolymer is obtained by the following addition reaction of formaldehyde and phenol under the condition of alkali catalysis:

[0037]

[0038] During this reaction, a mixture of monohydric phenolic alcohols and polyhydric phenolic alcohols is produced.

[0039] Then, the molecular chain growth reaction is carried out, and the reaction process is carried out between the hydroxymethyl group and the adjacent para-hydrogen of other phenols:

[0040]

[0041] Thereby obtaining a phenolic novolac prepolymer.

[0042] Potassium silicate 0.5kg, aluminum oxide 0.5kg, attapulgite 0.8kg join the phenolic resin prepolymer of 6kg liquid (can be liquid oligomer, or high-concentration alcohol solution, the phenolic resin prepolymer mentioned in the context of the present invention The weight of the polymer is calculated with the weight of the pure phenolic resin prepolymer, and th...

Embodiment 2

[0046] Potassium silicate 0.8kg, alumina 0.5kg, attapulgite 0.5kg add 10kg liquid phenolic resin prepolymer; 40kg aromatic polyamide (aramid fiber 1414) fiber, 25kg graphite fiber are added to the above phenolic resin prepolymer , extruded to form fibers, and thermally cured phenolic resin prepolymers to form hybrid fibers.

[0047] The mixed fiber formed above is blended with 10kg of asbestos fiber to form a textile, and the textile is soaked in water for 50 minutes to form the first layer of fabric.

[0048]The polytetrafluoroethylene fiber layer, bamboo fiber fabric, ramie fiber fabric or bamboo fiber and ramie fiber blended fabric layer, and nylon fiber and cotton fiber fabric are sequentially superimposed on the first layer of fabric to form a high temperature resistant protective clothing fabric.

Embodiment 3

[0050] Add 1kg of potassium silicate, 0.8kg of alumina, and 1kg of attapulgite to 8kg of liquid phenolic resin prepolymer, add 45kg of aromatic polyamide (such as aramid 1313), and 25kg of graphite fiber to the above phenolic resin prepolymer , to obtain a mixture.

[0051] 13kg of asbestos fiber is used as the core wire, and the mixture is co-extruded with the core wire by co-extrusion process, and the mixture is coated on the surface of the core wire, and the phenolic resin prepolymer is thermally cured, and the fiber of the skin-core structure is formed after cooling. It is then spun to form the first layer of fabric. Soak the first layer of fabric in water for 60 minutes and dry.

[0052] The polytetrafluoroethylene fiber layer, bamboo fiber fabric, ramie fiber fabric or bamboo fiber and ramie fiber blended fabric layer, and nylon fiber and cotton fiber fabric are sequentially superimposed on the first layer of fabric to form a high temperature resistant protective clothi...

Abstract

The invention provides high-temperature resistant protective clothing and a fabric thereof. The fabric comprises a first layer, a second layer, a third layer and a fourth layer which are sequentiallysuperposed, wherein the fourth layer is a nylon fiber and cotton fiber textile fabric; the third layer is a bamboo fiber fabric, a ramie fiber fabric or a bamboo fiber and ramie fiber blended fabric;the second layer is a polytetrafluoroethylene fiber layer; the first layer is aromatic polyamide, phenolic resin, graphite fiber and asbestos fiber textile; and the blended fabric of the first layer is added with alkali metal silicate, alumina and attapulgite. The high-temperature resistant protective clothing and the fabric thereof can obtain relatively consistent thermal deformation performance,and ensure good wearing comfort and service life of products under the high-temperature condition.

Description

technical field [0001] The invention relates to a protective clothing, in particular to a high temperature resistant protective clothing and fabrics for making the high temperature resistant protective clothing. Background technique [0002] High temperature resistant protective clothing is a variety of protective clothing for the safety protection of personnel working under high temperature or ultra-high temperature conditions, so as to avoid the heat source from harming the human body. It is required to have flame retardancy, liquid repellency, and no droplet generation during combustion , When exposed to heat, it can maintain the integrity and wearing comfort of clothing and other characteristics. High temperature resistant protective clothing is widely used in petroleum, chemical industry, metallurgy, shipbuilding, fire fighting, national defense and places with open flames, sparks, molten metal and flammable substances. [0003] American firefighting clothing is usuall...
