Embodiment 1

[0024] A kind of slurry that trumpet drum paper is used, by the raw material of following weight portion: 50 parts of wood pulp fibers, 20 parts of cotton fibers, 15 parts of natural silk, 5 parts of wool fibers, 0.5 parts of bulletproof fibers, 0.5 parts of nanocellulose , 1 part of special fiber, 0.4 part of glass fiber, 4 parts of phenolic resin, 1.5 parts of hydroxyethyl cellulose, 3 parts of flow aid and filter aid, 4 parts of dye direct black G, 3 parts of sizing agent, 0.6 part of dispersing The agent is polyethylene oxide (PEO), and nanocellulose is made of bacterial cellulose and aramid fiber in a mass ratio of 1:2. First, the wood pulp fiber, cotton fiber, natural silk, wool fiber, bulletproof fiber, nano cellulose, special fiber, glass fiber, phenolic resin and hydroxyethyl cellulose are dispersed to make a mixed fiber slurry, and then fluid aid is added. Filter (guar gum), dyestuff direct sun black G, sizing agent (alkyl ketene dimer) and dispersant polyethylene ox...

Abstract

The invention discloses slurry for drum paper of a horn. The slurry is prepared from the following components: wood pulp cellulose, cotton fibers, natural silk, wool fibers, bulletproof fibers, nano cellulose, special fibers, glass fibers, coal ash, phenolic resin, hydroxyethyl cellulose, a flow aid and filter aid, a dye, a sizing agent and a dispersant polyoxyethylene (PEO). The slurry is specifically prepared by the following steps: first, defibering and dispersing the wood pulp cellulose, cotton fibers, nano cellulose and the like to prepare mixed fiber slurry; then adding the chemical reagents; making paper through a paper machine; and then preparing the drum paper for the horn containing nano cellulose by means of follow-up and conventional preparation methods of the drum paper. The drum paper prepared by mixing the three fibers has excellent rigidity, soft performance and relatively high Young modulus, so that the clearness of high audio in the drum paper is improved greatly andthe service life of the drum paper is prolonged greatly.

Description

technical field [0001] The invention relates to the field of pulp and papermaking, in particular to a slurry for trumpet drum paper. Background technique [0002] At present, the materials used for trumpet drum paper on the market are generally paper cones, bulletproof cloth cones, aluminum, magnesium metal cones, polypropylene cones, wool fiber cones, ceramic cones, etc. The paper cone has the advantages of combining rigidity and flexibility, high internal damping, and easy to mix with other materials. The timbre performance is mainly the pulp used for trumpet drum paper plus other fiber materials or other functional materials, but the pulp used for mainstream trumpet drum paper is still pulp. The main reason is that the paper cone has the advantages of combining rigidity and flexibility, high internal damping, easy to mix with other materials, and low cost of slurry. The type of slurry contained in the speaker paper generally determines the sound quality of the speaker. ...
