Description
Technical field
The present invention relates to electro-acoustic product technical field, and in particular to the manufacture method that a kind of subwoofer rouses paper.
Background technology
Tire is produced with pavement friction in running car noise, the noise of electromotor, sound of the wind and automobile inner structure bar
Part, often makes bass effect weakened, and when especially speed is fast, due to the impact of noise, it is little that bass is heard.Therefore install
Appropriate high-performance subwoofer, lifts bass zone particularly important.
Drum paper is the main sound-generating element in loudspeaker, and tonequality quality and the drum paper of loudspeaker have much relations, and drum paper is typically led
To be made up of trunk and side, it is different materials that common bulging paper is mostly compound drum paper, i.e. trunk with side, is combined adhesion into one
Complete bulging paper.The common material of trunk is sheet, also there is PP materials, aluminum body, copper body etc..The common materials on side have foam,
Cloth, rubber, ESMA, TPU etc..
At present, the material of drum paper is mainly paper pulp plus other materials, and in recent years the different material entrance of multifrequency nature, has
Polypropylene, Carbon fibe, Titanium etc., or even diamond.But main flow or paper pulp, are 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 manufacture method, with gas leakage
Rate is high, distortion rate is high and sound horn, the shortcomings of bass acoustical quality is not good.
The content of the invention
For the problems referred to above, it is an object of the invention to provide the manufacture method that a kind of subwoofer rouses paper, what the method was obtained
The physical properties such as drum paper loft, damping and amortization, Lightness coordination of potent and mild therapies are lifted well, so as to obtain good sound
Effect, sound it is more soft with it is gentle and refined, obtain sound loosen, natural, tireless.
To achieve these goals, the technical solution used in the present invention is：
The manufacture method that a kind of subwoofer rouses paper, comprises the following steps：
(1) it is beaten：The water for accounting for beater volume 65-75% is added toward beater pond；By sulphite wood pulp or sulphuric acid
Salt wood pulp is put in the stock tank of beater and dissociates；Lower weight knife 2-2.5 hours after light knife 25-35 minutes under after free 15-25 minutes；
Paper pulp beating degree is surveyed to beating 2-2.5 hour, is reached and is griffed after the required beating number of degrees, obtain slurry, then added in 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 fully dissociates, by the Impurity removal in slurry, paper machine copy paper is delivered to, obtain taper paper
；
(3) cervical region is strengthened：Taper paper to obtaining is rushed after mesopore, and in mesopore cervical region engine sizing is adopted, and cervical region is entered
Row reinforcement is processed；
(4) varnish is sprayed：The taper paper surface that step (3) is obtained is carried out to spray varnish or full leaching varnish processed；
(5) glue spraying or whirl coating：Obtaining taper paper to step (4) first carries out surface overlap process, after overlap process
Cone paper surface spray or get rid of black light glue or dumb light glue, put into baking oven drying；
(6) material is cut out：Cloth is chosen, 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, adjust cutting and the stroke above cutting die, cut out material；
(7) molding：The selvedge obtained after material will be cut out and place the molding into the forming machine with upper/lower die with side is steeped, it is described
It is 185 ± 10 DEG C that mould temperature is gone up in selvedge shaping for 185 ± 10 DEG C, lower mould temperature, and molding time is 7 ± 3 seconds, and pressure is 0.3
±0.05MPa；It is 220 ± 5 DEG C that mould temperature is gone up in the bubble edge forming for 210 ± 5 DEG C, lower mould temperature, and molding time is 18 ± 4
Second, pressure is 0.3 ± 0.05MPa；By optimizing the temperature of molding, time and pressure and other parameters, make selvedge and bubble side not only into
Type is good, and the stickiness of selvedge, bubble side and taper paper after molding is good, and shaping efficiency is high；
(8) side gluing：Carried out at gluing on gluing machine using glue at binding face to selvedge, bubble side and taper paper
Reason；
(9) fit：After the glue at the binding face of selvedge, bubble side and taper paper dries, by selvedge, bubble side and taper
Paper is put and is fitted to make-up machine；
(10) suture and reinforcement：After suture selvedge, bubble side and the suture of taper paper, reinforcement glue is recycled to suture
Product afterwards carries out reinforcement.Carry out suture process before reinforcement first, make the cementability for rousing paper more excellent, to improve the audio of bulging paper.
Further, the manufacture method of subwoofer drum paper also include testing the product after laminating and reinforcement and
Packaging, the phenomenon for verifying as checking the product after reinforcement whether to have gummosis, bubble, leakage to mend.
Further, step (1) additive includes that dyestuff, salt, acrylic latex waterproofing agent and trimethyl phosphate are hard
Agent.
Further, the order of addition and using method of step (1) additive is：To first account for slurry weight 7-10%'s
Dyestuff is uniformly poured in slurry, is dissociated 5-8 minutes；Pour the Sal for accounting for slurry weight 2-3% in slurry fixation, dissociate 5-8 point
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 sclerosing agent is added in slurry and dissociated 10 minutes；Finally the aluminum sulfate for accounting for slurry weight 10-13% is added
Dissociate 10-15 minutes in slurry.
Further, step (4) cervical region strengthens being impregnation or gluing that the impregnation is that taper paper is punched into mesopore
By the positive and negative immersion glue of cervical region after journey external diameter, the gluing be by taper paper be steadily put into glue spreader turn on basin, use hairbrush
Or brush pen is stained with glue and is evenly coated in product cervical region, it is that acrylic latex toluene presses 1 that the cervical region strengthens glue used：3 mix
The glue for closing, or Bao Lilong foams and toluene are by 1：10 glue.
Further, step (5) the black light glue is that acrylic latex presses 8.5 with water：What 1.5 ratio was mixed
Glue, dumb light glue is that acrylic latex presses 8 with water：2 glue for mixing.
Further, the glue described in step (9) is that acrylic latex presses 9 with toluene:1 glue for mixing.
Further, the binding temperature described in step (9) be 130 ± 10 DEG C, the time be 8 ± 1 seconds, pressure be 0.294 ±
0.098MPa。
Further, the reinforcement glue described in step (10) is that 4278 black glue press 1 with first is stupid：9 ratio mixing and
Into glue.
In sum, as a result of above-mentioned technical proposal, beneficial effects of the present invention are：
(1) manufacture method of the invention improves subwoofer and rouses the bass tonequality of paper, and largely reduces distortion
Rate, the bulging paper loft for obtaining, damping and amortization is Lightness, and the physical property such as coordination of potent and mild therapies is lifted well, so that utilizing
The speaker of the drum paper obtains good audio, sound it is more soft with it is gentle and refined, obtain it is loosening, natural, be difficult it is tired
The sound of labor.
(2) glue bonding used in the manufacturing process of present invention drum paper is high, makes the bulging paper sealing that making is obtained
Well, and selvedge, the bubble outward appearance on side, soft durometer, thickness are moderate, there be damping well on bubble side, and draftability is strong, can play back out very
Real bass.
