Abstract: The present application provides a sound adsorbing material, including a microporous material and an adsorbate gas adsorbed in the microporous material. The microporous material includes a zeolite molecular sieve, and the zeolite molecular sieve has a framework and extra-framework cations. An adsorption capacity of the adsorbolite molecular sieve to the adsorbate gas is greater than an adsorption capacity of the adsorbolite molecular sieve to air. The present disclosure further provides a speaker box adopting the sound adsorbing material. Compared with the related art, the sound adsorbing material provided by the present disclosure has good application effects, and the speaker box using the sound adsorbing material has a better low frequency acoustic performance.

Abstract: A prepreg is a blend of a fiber reinforcement, a matrix resin and a filler. Based on 100 parts by mass of the prepreg, the fiber reinforcement is 20-60 parts by mass, the matrix resin is 20-65 parts by mass, and the filler is 10-40 parts by mass. The filler is a flame-retardant organic microsphere or a blend of the flame-retardant organic microsphere and an inorganic filler, and the particle size of the filler is preferably 0.1 microns to 15 microns. A copper-clad laminate and a printed circuit board are also disclosed. In various embodiments, the stability of material properties of the prepreg can be improved, the prepreg manufacturing process is simplified, the prepreg production efficiency is improved. Due to the high production efficiency of the prepreg, the manufacturing cost of the prepreg, the copper-clad laminate and the printed circuit board can be reduced.
