Problems solved by technology

[0004] At present, airgel is mostly used as heat insulation material, and oily coating is used as heat shielding material to prepare infrared stealth fabrics. On the one hand, oily coatings have poor compatibility with fabrics, and it is difficult to find suitable light and thin fabrics. Generally, it is necessary to use Multi-layer dipped cloth ensures the adhesion between the coating and the substrate. On the other hand, the airgel material sheds powder seriously, has poor environmental protection, and is heavy. The fabrics made of it are poor in practicability and mechanical properties

preparation example Construction

[0023] The preparation method of fabric provided by the invention comprises the following steps:

[0024] The thermal radiation shielding material is coated on the surface of the cloth and cured to obtain the coated cloth. In this step, the thermal radiation shielding material can be coated on the surface of the cloth by one or more combinations of brushing, spraying or dipping, wherein the coating is carried out on one side of a piece of cloth, and the Coating is performed on both sides of another piece of fabric, and then cured at 90° C. to 150° C. for 25 minutes to 45 minutes to obtain a coated fabric. In this step, the heat radiation shielding material is a water-based paint, and the heat radiation shielding material is a water-based low-infrared emissivity paint, wherein the emissivity of the paint is 0.2 to 0.6, and the cloth is one or more of polyester, polyester cotton, and nylon. Various combinations. In this step, the use of water-based low-infrared emissivity coat...

Embodiment 1

[0028] A water-based low-infrared emissivity paint with an infrared emissivity of 0.2 is applied to the nylon cloth by brushing, wherein one side of a piece of cloth is coated, and the other side of the cloth is coated on both sides, and then, Curing at 90°C for 45 minutes to obtain a coated fabric. The fabric coated on one side is used as the inner layer of the fabric, and the fabric coated on both sides is used as the outer layer of the fabric. The polyethylene material (XPE) is used as the middle layer, wherein the coated side of the single-side coated fabric is in direct contact with the chemically cross-linked polyethylene material (XPE), and finally composited by sewing to obtain a fabric.

Embodiment 2

[0030] A water-based low-infrared emissivity paint with an infrared emissivity of 0.6 is applied to the nylon cloth by brushing, wherein one side of a piece of cloth is coated, and the other side of the cloth is coated on both sides, and then, Curing at 150°C for 25 minutes to obtain a coated fabric. The fabric coated on one side is used as the inner layer of the fabric, and the fabric coated on both sides is used as the outer layer of the fabric. At the same time, two layers of 2mm-thick The chemically cross-linked polyethylene material (XPE) is used as the middle layer, wherein the coated side of the single-sided coated fabric is in direct contact with the chemically cross-linked polyethylene material (XPE), and finally compounded by sewing to make get the fabric.

Abstract

The invention provides fabric and a preparation method thereof. Cloth is coated with a heat shielding material, and a heat insulation material serving as an intermediate layer is clamped in the middleof the cloth coated with the heat shielding material, so as to prepare the fabric used for infrared stealth. In the fabric, a water-based low-infrared-emissivity coating is adopted, so that the compatibility of the coating and the cloth can be improved, and the adoption of a plurality of layers of impregnated fabric is avoided, therefore, the stronger adhesion between the coating and the cloth isensured, and the characteristics of being light and thin of the fabric are improved; additionally, water-based paint is adopted, so that the environmental protection property of the fabric can be improved, and the harm to the health of a user is reduced. The heat insulation material is adopted, so that the high gluing property with the fabric can be ensured, the fabric can be prevented from falling off, the mechanical property of the fabric can be enhanced, and the service life of the fabric is prolonged, and therefore, the practicability of the fabric is improved. The fabric prepared by theinvention can be applied to products such as battle-dress uniforms, tents, tarpaulin and the like for improving the camouflage abilities of the products.

Description

technical field [0001] The invention relates to the field of materials, in particular to a fabric and a preparation method thereof. Background technique [0002] With the development of science and technology, the detection methods used to detect targets are increasingly advanced. In order to prevent military targets and weapons from being discovered and destroyed by the enemy, the use of stealth materials to improve their survivability has become an important aspect of military technology development. The infrared detection system relies on the difference in thermal radiation caused by the temperature of the target and the background itself to detect and identify the target. [0003] Infrared stealth fabrics are mainly aimed at the detection of infrared thermal imaging cameras. Infrared thermal imaging cameras use the thermal radiation imaging of targets. They have good concealment, long night vision distance, strong anti-interference ability, and are suitable for use in va...
