Abstract

The invention discloses slurry for loudspeaker cone paper, and belongs to the technical field of electroacoustic products. The slurry is mainly formed by the mixing and stirring of the following raw materials by weight: 45-65 parts of wood pulp, 15-30 parts of sisal hemp, 10-20 parts of cotton pulp, 10-20 parts of kapok, 0.3-1 parts of bulletproof fiber, 0.1-0.8 parts of wool, 0.05-0.5 parts of glass fiber, 2-8 parts of dye, 1-5 parts of salt, 3-8 parts of waterproof agent, 3-8 parts of hardening agent, 3-8 parts of flexibilizer, 3-8 parts of conditioning agent, 0.5-5 parts of potassium polymetaphosphate, 0.5-5 parts of polyoxyethylene, 0.5-5 parts of urea resin, 0.2-3 parts of chitinous substances, 0.2-3 parts of pineapple fiber. The slurry is good in decontamination and antiwrinkling capabilities, and is good in force of flocculation, toughness and strength, thereby enabling cone paper made of the slurry to be good in sound effect, greatly improving the antiwrinkling capability and mechanical performance, and prolonging the service life.

Description

technical field [0001] The invention relates to the technical field of electroacoustic products, in particular to a slurry for speaker drum paper. Background technique [0002] At present, the material of drum paper is mainly the slurry used for speaker drum paper plus other materials. In recent years, various materials with different characteristics have entered, such as polypropylene, carbon fiber, metal titanium, etc., and even diamond. But the mainstream is still the slurry for speaker drum paper. On the one hand, the slurry for speaker drum paper is cheap, and on the other hand, the slurry for speaker drum paper is easy to make the complex curved surface required by the speaker diaphragm. The shape of the drum paper can only determine 70% of the curve, and what plays a decisive role in the sound of the speaker is the formula of the slurry used for the drum speaker drum paper. Existing slurry formulas for producing loudspeaker drum paper are usually composed of wood fib...
