Description
Technical field
The present invention relates to electro-acoustic product technical fields, and in particular to a kind of production method of subwoofer drum paper.
Background technique
Tire and structure bar in the noise of pavement friction generation, the noise of engine, sound of the wind and automobile in running car
Part often makes bass effect weakened, and when especially speed is fast, due to the influence of noise, bass is heard seldom.Therefore it installs
It is particularly important to promote bass zone for high-performance subwoofer appropriate.
Drum paper is the main sound-generating element in loudspeaker, and the sound quality quality and drum paper of loudspeaker have much relations, and drum paper is generally main
It to be mostly compound bulging paper by trunk and Bian Zucheng, common drum paper, i.e., trunk and side are different materials, and compound adhesion is at one
Complete drum paper.The common material of trunk is sheet, also there is PP material, aluminum body, copper body etc..The common materials on side have foam,
Cloth, rubber, ESMA, TPU etc..
Currently, the material of drum paper is mainly paper pulp plus other materials, the different material of multifrequency nature enters in recent years, has
Polypropylene, Carbon fibe, Titanium etc. or even diamond.But mainstream or paper pulp, it is on the one hand due to paper pulp low cost
Honest and clean, another aspect paper pulp may be readily formed as complex-curved required by Loudspeaker diaphragm.In existing bulging paper production method, there is gas leakage
Rate is high, distortion rate is high and sound horn, the disadvantages of bass acoustical quality is bad.
Summary of the invention
In view of the above-mentioned problems, the object of the present invention is to provide a kind of production method of subwoofer drum paper, what this method obtained
Drum paper fluffy degree, damping and amortization, the Lightness physical properties such as temper toughness with gentleness are promoted well, to obtain good sound
Effect, sound it is more soft with it is gentle and refined, obtain sound loosen, natural, tireless.
To achieve the goals above, the technical solution adopted by the present invention are as follows:
A kind of production method of subwoofer drum paper, comprising the following steps:
(1) it is beaten: the water for accounting for beater volume 65-75% being added into beater pond；By sulphite wood pulp or sulfuric acid
Salt wood pulp, which is put into the stock tank of beater, to dissociate；Under after 15-25 minutes free lower weight knife 2-2.5 hours after light knife 25-35 minutes；
Paper pulp beating degree is surveyed after to beating 2-2.5 hours, is griffed after reaching required beating degree, is obtained slurry, then be added into slurry
Additive；
The paper pulp raw material of the beating is true qualities kp softwood pulp, bleached sulphate softwood pulp or cotton pulp raw material；
(2) copy paper: after additive sufficiently dissociates, the impurity in slurry being removed, and is sent to paper machine copy paper, is obtained taper paper
?；
(3) neck reinforce: after rushing mesoporous to the taper paper of acquisition, mesoporous neck use engine sizing, to neck into
Row reinforcement processing；
(4) it sprays varnish: spray varnish or full leaching varnish working process is carried out to the taper paper surface that step (3) obtain；
(5) glue spraying or whirl coating: obtaining taper paper to step (4) first and carry out the processing of surface overlap, after overlap processing
Cone paper surface spray or get rid of black light glue or dumb light glue, put and dried into baking oven；
(6) it cuts out material: choosing cloth, cutting die is put on institute's fabric dividing material after cloth is drawn neatly on fabric cutter by code, put
Put cutting die well, the stroke above adjustment cutting and cutting die cuts out material；
(7) it forms: the selvedge obtained after material will be cut out and bubble side is placed into the molding machine with upper/lower die and formed, it is described
Upper mold temperature is 185 ± 10 DEG C in selvedge shaping, lower die temperature is 185 ± 10 DEG C, and molding time is 7 ± 3 seconds, pressure 0.3
±0.05MPa；Upper mold temperature is 210 ± 5 DEG C in the bubble edge forming, lower die temperature is 220 ± 5 DEG C, and molding time is 18 ± 4
Second, pressure is 0.3 ± 0.05MPa；By optimizing molding temperature, time and pressure and other parameters, make selvedge and bubble side not only at
Type is good, and selvedge after molding, bubble side and the stickiness of taper paper are good, and shaping efficiency height；
(8) in gluing: being carried out at gluing on gluing machine when to selvedge, bubble and at the binding face of taper paper using glue
Reason；
(9) it is bonded: after the glue at the binding face of selvedge, bubble side and taper paper dries, by selvedge, bubble side and taper
Paper is put to being bonded on make-up machine；
(10) suture and reinforcement: after suture selvedge, bubble side and the suture of taper paper, recycle reinforcement glue to suture
Product afterwards carries out reinforcement.Suture processing is carried out before reinforcement first, keeps the cementability for rousing paper more excellent, to improve the audio of drum paper.
Further, the production method of subwoofer drum paper further include test to fitting with the product after reinforcement and
Packaging, it is described to verify as examining whether the product after reinforcement has the phenomenon that gummosis, bubble, leakage are mended.
Further, step (1) described additive includes that dyestuff, salt, acrylic latex waterproofing agent and trimethyl phosphate are hard
Agent.
Further, the order of addition and application method of step (1) described additive are as follows: will first account for slurry weight 7-10%'s
Dyestuff uniformly pours into slurry, dissociates 5-8 minutes；The salt for accounting for slurry weight 2-3% is poured into fixation in slurry, is dissociated 5-8 points
Clock；The acrylic latex waterproofing agent for accounting for slurry weight 10-13% is added in slurry and is dissociated 10-15 minutes；Slurry weight 10- will be accounted for
13% trimethyl phosphate curing agent, which is added in slurry, to dissociate 10 minutes；Finally the aluminum sulfate for accounting for slurry weight 10-13% is added
Dissociate 10-15 minutes in slurry.
Further, step (4) neck is reinforced being impregnation or gluing, and the impregnation is that taper paper is punched mesoporous
By the positive and negative immersion glue of neck after journey outer diameter, the gluing is that taper paper is steadily put into the turning on basin of glue spreader, uses hairbrush
Or writing brush is stained with glue and is evenly coated in product neck, it is that acrylic latex toluene is mixed by 1:3 that the neck, which reinforces glue used,
Glue made of conjunction or Bao Lilong foam and toluene are by glue made of 1:10.
Further, step (5) the black light glue is that acrylic latex and water are mixed in the ratio of 8.5:1.5
Glue, dumb light glue are the glue that acrylic latex and water are mixed by 8:2.
Further, glue described in step (9) is the glue that acrylic latex and toluene are mixed by 9:1.
Further, binding temperature described in step (9) be 130 ± 10 DEG C, the time be 8 ± 1 seconds, pressure be 0.294 ±
0.098MPa。
Further, reinforcement glue described in step (10) is 4278 black glue and the stupid ratio in 1:9 of first mixes and
At glue.
In conclusion by adopting the above-described technical solution, the invention has the benefit that
(1) production method of the invention improves the bass sound quality of subwoofer drum paper, and largely reduces distortion
Rate, obtained drum paper fluffy degree, damping and amortization is Lightness, and the physical properties such as temper toughness with gentleness are promoted well, to make to utilize
The loudspeaker of the drum paper obtains good audio, sound it is more soft with it is gentle and refined, obtain it is loosening, natural, be not easy it is tired
The sound of labor.
(2) glue caking property used in the manufacturing process of present invention drum paper is high, makes prepared bulging paper leakproofness
Well, and selvedge, the appearance for steeping side, hardness, thickness are moderate, and there are also damping well, draftability is strong, can play back out very on bubble side
True bass.
