Abstract
The invention relates to a waterproof cone used for a loudspeaker and a manufacturing method thereof. The waterproof cone is technically characterized in that the waterproof cone is formed by compounding waterproof composite edges with a waterproof paper cone, and the waterproof composite edge is made of a proper material. The waterproof paper cone adopts the following manufacturing processing steps: firstly, raw materials and agents are prepared proportionally; and secondly, the waterproof paper cone is formed through the steps of pulping, filtering, gluing, pulp dredging and hot pressing, rubberizing and die cutting, and hot pressing and compounding. The waterproof cone has good waterproof performance after being subjected to a waterproof process, can not only be applied to the dry environment, but also to the wet environment, and overcomes the fatal weakness of the poor waterproof performance of the original waterproof cone.
Description
One, technical field:
The invention belongs to the water-proof cone for loudspeaker technical field, a kind of specifically water-proof cone for loudspeaker.
Two, background technology:
At present, general, universal, cheap loud speaker is all based on cone.Because cone loudspeaker has advantages such as tone color nature, some high-grade loud speaker also has use.It is poor that but the deadly defect of cone is a water resistance, at wet environment or when having water logging to arrive diffuser, cone performance, tonequality changed, even the sound basin produced destroy the destruction that finally causes a whole set of loud speaker.
Three, summary of the invention:
At the defective of above-mentioned diffuser water resistance difference, it is good to the invention provides a kind of water resistance, and cone reaches water proofing property impervious water-proof cone for loudspeaker and manufacture method thereof more than 96 hours.
Technical scheme of the present invention is: water-proof cone is composited by waterproof compound boundary and waterproof paper awl, and the waterproof compound boundary has water proof rubber limit, waterproof selvedge, waterproof foam limit etc., and the raw material on rubber limit adopts elastomeric materials such as NBR and SBR; Selvedge adopts extraordinary homemade A glue as the frictioning closed material; The foam limit is hot-forming after adopting Q2 or extraordinary impregnating agent to handle.
The raw material of paper awl and dosing and manufacturing technology steps are:
1. raw material and dosing: raw material: single paper pulp or multiple paper pulp is the mixed pulp of ratio on request; Dosing: dye dosage be the absolute dried paper pulp amount 7%～12%, addition of aluminum sulfate be the absolute dried paper pulp amount 6%～10%, amphiprotic polyacrylamide BR-2300 consumption be the absolute dried paper pulp amount 1%～5%, polyamide epoxy polyamine chloropropane SW-010 consumption be the absolute dried paper pulp amount 1%～4%, resin PC-8000 consumption is 1%～3% of absolute dried paper pulp amount.
2. manufacturing technology steps:
(1) making beating: in beater, put into clear water, power-on, the paper pulp that pre-preg is handled tears up progressively puts into beater, makes beating consistency be controlled at 2.5%～3.0%.
(2) filter: the paper pulp of having discongested is put into the filter pulp bucket, and water flushing beater makes paper pulp all flow into the filter pulp bucket, the moisture content in the elimination paper pulp;
(3) applying glue: the paper pulp of elimination moisture is transferred in the mixer, added water, concentration is controlled at about 2.5%～3.0%; power-on adds dye solution, stirs 20min; add aluminum sulfate solution; stir 20min, add amphiprotic polyacrylamide BR-2300, continue to stir 10min; add polyamide epoxy polyamine chloropropane SW-010; stir 10min, add resin PC-8000, shut down after stirring 10min again.When adding in the paper pulp, rosin to note controlling well pH value scope at 4.0-4.5.
(4) drag for slurry, hot-forming: ready slurry is mixed, send into the pulp grinder that drags for that mould is housed and drag for slurry, take out satisfactory cone blank from mould, put into the cone hot pressing die, take out hot-forming back.
(5) gluing, die-cut: with the position of cone cone top part appointment, the spray liniment of the glue of dipping regulation or spraying regulation is die-cut into the paper awl after the drying.
(6) hot pressing is compound: with paper awl and waterproof compound boundary gluing, hot pressing composite molding then.
3. advantage of the present invention: after paper awl of the present invention was handled through waterproof technology, water resistance was good, not only was adapted at the dry environment use but also was suitable for use under the wet environment, had overcome the deadly defect of cone water resistance difference in the past; The chemical raw material that paper awl and compound boundary water-proofing treatment are used all is an environment-protecting asepsis, and unharmful, toxic gas reach the requirement of environment-friendly waterproof.
Four, description of drawings:
Fig. 1, water-proof cone structural representation.
Among the figure 1, the waterproof compound boundary; 2, waterproof paper awl.
Five, embodiment:
Below technology of the present invention and operating process are described further:
(1) at first be the water-proofing treatment of compound boundary: as use Cushions, adopt elastomeric materials such as NBR and SBR; As use selvedge, adopt A glue as the frictioning closed material; As use the foam limit, and adopt Q2 impregnating agent processing back hot-forming, can both reach waterproof requirement.
(2) making beating: in beater, put into clear water, power-on, the paper pulp that pre-preg is handled tears up progressively puts into beater, makes beating consistency be controlled at 2.5%～3.0%, requires making beating in accordance with regulations.
(3) filter: the paper pulp of having discongested is put into the filter pulp bucket, and water flushing beater makes paper pulp all flow into the filter pulp bucket, the moisture content in the elimination paper pulp.
(4) applying glue: the paper pulp of elimination moisture is transferred in the mixer; add water; concentration is controlled at about 3.0%, and power-on adds dye solution; consumption is 10% of an absolute dried paper pulp amount; stir 20min, add aluminum sulfate solution, consumption is 8% of an absolute dried paper pulp amount; stir 20min; add amphiprotic polyacrylamide BR-2300, consumption is 2% of an absolute dried paper pulp amount, continues to stir 10min; add polyamide epoxy polyamine chloropropane SW-010; consumption is 2% of an absolute dried paper pulp amount, stirs 10min, adds resin PC-8000; consumption is 2% of an absolute dried paper pulp amount, shuts down after stirring 10min again.When adding in the paper pulp, rosin to note controlling well pH value scope at 4.0-4.5.
(5) drag for slurry, hot-forming: ready slurry is mixed, send into the pulp grinder that drags for that installs mould and drag for slurry, take out satisfactory cone blank from mould, put into paper awl hot pressing die, take out hot-forming back.
(6) gluing, die-cut: with the position of cone cone top part appointment, the spray liniment of the glue of dipping regulation or spraying regulation is die-cut into the paper awl after the drying.
