Abstract

The invention discloses an aerogel heat insulation sleeve for a battery. The aerogel heat insulation sleeve for the battery comprises a cylindrical sleeve body with one end sealed, wherein grooves are formed in the sleeve body in an axis direction, and the number of the grooves is 1-4, and the grooves are evenly distributed in the circumferential direction. The preparation method comprises the following steps: (1) continuously pumping uniform superfine fiber slurry into a hollow special-shaped mold, allowing fibers to be stacked in the mold and to be automatically woven and formed, and then carrying out drying and demolding to obtain a superfine fiber sleeve; (2) preparing a silicon dioxide micelle particle solution; (3) adding the silicon dioxide micellar particle solution into the superfine fiber sleeve, and then conducting treatment by using a mechanical wave dispersion method to obtain a heat insulation sleeve gel preform; (4) putting the heat insulation sleeve gel preform into an alcoholic solution of a water repellent for modification; and (5) prefabricating the modified heat insulation sleeve gel, and conducting drying and demolding to obtain the aerogel heat insulation sleeve for the battery. The sleeve is uniformly formed, and the defects of non-uniform gum dipping, bending, cavities and the like are effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of battery protection, and in particular relates to an airgel heat-insulating sleeve for batteries and a preparation method thereof. Background technique [0002] Heat insulation materials are divided into two categories: porous materials and heat reflective materials. The former uses the pores contained in the material itself to insulate heat, because the thermal conductivity of the air or inert gas in the pores is very low, such as foam materials, fiber materials, etc.; the latter material has a high reflection coefficient and can reflect heat. Such as gold, silver, nickel, aluminum foil or metal-plated polyester, polyimide film, etc. The aerospace industry has strict requirements on the weight and volume of the insulation materials used, and often requires them to have sound insulation, vibration reduction, and corrosion resistance. Due to the excellent characteristics of light weight, softness, impact ...
