Abstract

The invention relates to shading and damping foam which comprises a PET (polyethylene glycol terephthalate) protection film layer, a shading rubber belt layer and a polypropylene shading and damping foam layer, wherein the shading rubber belt layer and the polypropylene shading and damping foam layer are fixed on the same side of the PET protection film layer, the shading rubber belt layer comprises a black and white base material layer and a clear binder layer, the black and white base material layer is fixed on the PET protection film layer through the clear binder layer, the polypropylene shading and damping foam layer comprises a polypropylene shading and damping foam layer and an acrylic acid binder layer, the polypropylene shading and damping foam layer is fixed on the PET protection film layer through the acrylic acid binder layer. The shading and damping foam provided by the invention has advantages of good heat retaining property, thermal insulation, buffering and damping, sound absorption, sealing and the like, and can be used at a temperature of -40-105 DEG C. The shading and damping foam has ultrahigh adhesive property, good adhesive property and good durability under high-temperature and low-temperature environments, and long service life.

Description

technical field [0001] The invention relates to the technical field of electronic products, in particular to a light-shielding and shock-absorbing foam used in notebook computers. Background technique [0002] With the rapid development of the electronic industry, notebook computers are widely used in various fields. Due to the more and more functions, the internal structure of the product tends to be complicated, and the electronic components are becoming more and more numerous. At the same time, because people have higher and higher requirements on the appearance of such electronic products, for example, the Logos on many notebook computers now have increased lighting design, so as to increase the aesthetics of the notebook computer. [0003] The Logo design on the above-mentioned notebook computer has new requirements for the foam around the Logo. Specifically, the foam around the logo is required to have excellent light-shielding properties, heat insulation, cushioning ...
