Abstract

The invention discloses a preparation method of an intelligent early-warning and temperature-resistant material. The preparation method comprises the following steps: 1, mixing silicon resin and a solvent according to the mass ratio being (10-30):(50-70); 2, adding a dispersing agent into the mixture in the step 1 and stirring, and adding temperature-changing powder and stirring uniformly to obtain coating slurry, wherein the mass ratio of the dispersing agent to the silicon resin is (90-95):(2-5), and the mass ratio of the temperature-changing powder to the silicon resin is (90-95):(1-1.5); 3, coating a silicate fiber layer with the coating slurry in the step 2, wherein the coating thickness is 2 to 20 silk, and the gluing quantity is 30 to 220 g/m<2>; and 4, performing curing treatment on the coated silicate fiber layer to obtain the intelligent early-warning and temperature-resistant material. The preparation method of the intelligent early-warning and temperature-resistant material has the following advantages of actively performing early warning, reducing skin allergy probability, improving wearing comfort, having high material internal combining firmness and facilitating postprocessing cutting to make any models.

Description

technical field [0001] The invention relates to the technical field of functional textiles, in particular to a preparation method of an early warning temperature-resistant material and an early warning temperature-resistant material based on the method. Background technique [0002] Heat-resistant materials in the prior art, such as glass fiber-coated PTFE resin high-temperature cloth, glass fiber-coated resin temperature-resistant cloth, aramid fabric, carbon fiber finishing fabric, polyimide fabric, glass limit fabric, etc., are mostly passive. Heat-resistant protective material. That is, effective heat insulation, flame retardancy, and protection are carried out within the allowable temperature range of the material. However, when the external temperature changes or exceeds the limit temperature of the material, since the material itself cannot provide an active warning function, the material will be burned, lose its protective function, and cause burns and other situati...
