Problems solved by technology

[0003] 1. Adhesive materials such as mineral wool, glass wool, and rock wool products are used. When these materials are used in facilities with special parts and strange shapes, it is difficult to meet the heat insulation requirements, cannot resist vibration, often falls off, and is not easy to install or maintain. Defects;
[0004] 2. Improper material selection, such as rock wool, glass wool, mineral wool, asbestos products and other insulation materials are easy to pulverize under high temperature conditions
There are many heat insulation materials that use phenolic resin as a binder, which is easy to decompose and volatilize at high temperature, pollute the environment, generate dust during installation and construction, and be harmful to the human body
[0005] 3. Fiber products generally have light bulk density, are not resistant to vibration, and have extremely poor tensile strength. If used on equipment and transportation facilities with large vibrations, they are easy to fall off and have a short life; moreover, a large number of external protective materials are required, such as aluminum plates, galvanized iron sheets, etc. , not easy to install and difficult to maintain
[0006] 4. At present, some insulation materials cannot be used for heat preservation and fire protection of food, medicine and scientific research equipment
[0007] The above several existing heat insulation products have different degrees of shortcomings, and it is difficult to apply to special equipment and special industries, especially special-shaped equipment and equipment with large vibration

Embodiment 1

[0028] The insulation temperature is between 600°C and 800°C.

[0029] The inner layer is made of aluminum silicate fiber, cotton fiber and stainless steel wire at 80% kg / m 3 , 15%kg / m 3 , 5%kg / m 3 The ratio is woven into a 3mm-5mm interlaced fabric as the inner layer. The performance of this inner layer is high temperature resistance, tensile strength, wear resistance and non-combustibility.

[0030] The middle layer is made of 10mm-20mm aluminum silicate cotton felt with a density of 128kg / m 3 .

[0031] The surface layer is made of surface-coated polytetrafluoroethylene inorganic fiber non-woven fabric and treated with high-temperature resin. The surface layer has the functions of waterproof, oil-proof and fire-proof.

[0032] The above-mentioned two or three layers or even multiple layers of materials can be made into a heat-insulating protective clothing by sewing them together.

Embodiment 2

[0034] The heat insulation temperature is 600°C-800°C.

[0035] The inner layer is made of aluminum silicate fiber, cotton fiber and stainless steel wire at 87% kg / m 3 , 8%kg / m 3 , 5%kg / m 3 The ratio is woven into a 3mm-5mm interlaced fabric as the inner layer. The performance of this inner layer is high temperature resistance, tensile strength, wear resistance and non-combustibility.

[0036] The middle layer is made of composite silicate aluminum-magnesium cotton felt, with a density of 70-100kg / m 3 .

[0037] The surface layer is coated with polytetrafluoroethylene special glass fiber fabric and treated with high-temperature resin. The surface layer has the functions of waterproof, oil-proof and fire-proof.

[0038] The upper material can be made into a heat-insulating protective clothing by bonding the upper material into one body.

Embodiment 3

[0040] The heat insulation temperature is 1000°C-1200°C.

[0041] The inner layer is made of zirconium-containing fiber fabric, which is resistant to high temperature, tensile, wear-resistant and non-combustible.

[0042] The middle layer has a thickness of 40mm-80mm and a density of 190kg / m 3 Zirconium fiber cotton felt.

[0043] The surface layer is made of special glass fiber fabric coated with polytetrafluoroethylene, with a thickness of 0.8mm.

[0044] The materials are sewed together with high-temperature-resistant threads to make heat-insulating protective clothing.
