Abstract

The invention discloses paper pulp, and belongs to the technical field of electro-acoustic products. The paper pulp is mainly prepared by mixing and stirring the following raw materials in parts by weight: 45-65 parts of wood pulp, 15-30 parts of sisal hemp, 10-20 parts of cotton pulp, 10-20 parts of bombax malabaricum flowers, 0.3-1 part of bulletproof fibers, 0.1-0.8 part of wool, 0.05-0.5 part of glass fibers, 2-8 parts of dye, 1-5 parts of table salt, 3-8 parts of a water-proofing agent, 3-8 parts of a hardener, 3-8 parts of a flexibilizer, 3-8 parts of an adjusting agent, 0.1-1 part of sodium polystyrene sulfonate, 0.1-1 part of poly dimethyl diallyl ammonium chloride and 0.1-0.5 part of potassium polymetaphosphate. The cohesive force, the tenacity and the intensity of the paper pulp are favorable, cone paper made from the paper pulp not only has soft sound quality, but also has favorable mechanical properties, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of electroacoustic products, in particular to pulp. Background technique [0002] The main component of fiber in pulp is cellulose, and there are also substances such as hemicellulose, lignin, resin, pigment, pectin and ash to varying degrees. Among them, cellulose and hemicellulose are the basic components needed for pulp. [0003] At present, the material of speaker drum paper is mainly pulp plus other materials. In recent years, a variety of materials with different characteristics have entered, such as polypropylene, carbon fiber, metal titanium, etc., and even diamond. But the mainstream is still paper pulp. On the one hand, it is because of the low cost of pulp, and on the other hand, pulp is easy to make the complex curved surface required by the horn diaphragm. The shape of the drum paper can only determine 70% of the curve, and the formula of the drum paper slurry plays a decisive role in the soun...
