Embodiment
Clearer for technical problem, technical scheme and beneficial effect that the present invention will be solved, below in conjunction with embodiment, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
The embodiment of the invention provides a kind of glue, and it comprises ABS material or/and sound box waste material, acetone component, and ABS expects or/and the weight ratio of sound box waste material total amount and acetone is 1: 1.85 ± 25%.
Above-mentioned ABS material is the copolymer resin that is formed by vinyl cyanide, divinyl and three kinds of monomer copolymerizations of vinylbenzene, and this ABS material is called the ABS virgin material again; The sound box waste material is the Powdered or block waste material of pulverizing or smashing and obtain after sound box of scrapping or airduct are cleaned, dry, and this sound box waste material is called the ABS reclaimed materials again.
When above-mentioned glue involatile constituent was the mixture of ABS material and sound box waste material, the ABS material was preferably 1~10 with the weight ratio of sound box waste material: 10~1.
This glue involatile constituent is consistent with the composition of sound box, airduct, and the waste product that raw material can be taken from audio amplifier, airduct is as raw material, environmental protection; Economize on resources, reduced production cost, simultaneously; Make glue can be effectively and audio amplifier, airduct bonding, thereby improved the bonding strength of this glue; The solid colour of glue involatile constituent and sound box, airduct has been eliminated the vestige of audio amplifier obvious glue in the past, makes airduct and sound box reach the effect that merges fully, has strengthened the attractive in appearance of product; Solvent in the glue is volatile at normal temperatures, has shortened time of drying, has improved the production efficiency of enterprise.
The above-mentioned glue preparation method that the embodiment of the invention provides, it comprises the steps:
(1) add the ABS material by prescription or/and sound box waste material, acetone, and stir and form mixture, wherein, prescription is that the ABS material is or/and the weight ratio of sound box waste material total amount and acetone is 1: 1.85 ± 25%;
(2) the above-mentioned mixture of regular or irregular stirring is expected or/and the sound box waste material dissolves fully until ABS;
(3) pack and obtain described glue.
In the above-mentioned step (1) with ABS material or/and sound box waste material (the ABS virgin material is or/and the ABS reclaimed materials) mixes with acetone and stirs is that acceleration ABS expects or/and the dissolving of sound box waste material for ABS expects or/and the sound box waste material fully mixes with acetone.Sound box waste material in this step is powder or the blocky sound box waste material of pulverizing or smashing and obtain after sound box of scrapping or airduct are cleaned, dry.
Regular or irregular stirring is in order to reduce the ABS material or/and the strength of fluid around the sound box waste material in the above-mentioned step (2); Thereby make acetone solvent quicken to the ABS material or/and the surface of sound box waste material and intramolecule diffusion; Thereby further quicken the ABS material or/and the dissolving of sound box waste material; Preferred stirring is regularly regularly stirred preferred whenever at a distance from 4~5 hours stirring 10~30min.
Pack right and wrong in the above-mentioned step (3) and prevented the acetone volatilization of easy volatile, thereby made the gluing performance of glue forfeiture.
Need not heat step and glue stove of above-mentioned glue preparation method boils technology, when the configuration of this glue is got the raw materials ready, only need the ABS material or/and the sound box waste material dissolve in acetone, mixing gets final product, technology simply, good reproducibility, stable performance, with low cost.
A kind of audio amplifier air duct gluing method that the embodiment of the invention provides, it comprises the steps:
Airduct is put into the airduct groove of sound box, and corresponding on the position with the glue post of sound box;
Glue is clicked and entered sound box Jiao Zhuchu, and wherein, described glue comprises ABS material or/and sound box waste material, acetone component, and ABS expects or/and the sound box waste material total amount and third weight ratio by ketone are 1: 1.85 ± 25%;
Treat glue curing, thereby airduct is fixed on the sound box.
Airduct preparation method in the above-mentioned step (1) comprises the steps: that a. puts into audio amplifier airduct mould with the ABS material and pours into a mould injection moulding; B. with mold heated, mould is preferably continued heating 15~30 seconds down at 65~80 ℃, make the fusion of ABS material; C. cool off, typing, the demoulding obtain described airduct finished product.
The glue amount of clicking and entering is preferably 0.001~0.003kg/ glue post in the above-mentioned step (2).
In the above-mentioned step (3), only need at normal temperatures, treat that glue is clicked and entered sound box 1 glue post 4 places after, airduct 2 is fixed in until dried on the sound box 1, thereby makes airduct 2 firmly and accurately be adhesively fixed on the sound box 1.
A kind of audio amplifier that the embodiment of the invention provides; Comprise sound box 1 and airduct 2; Described casing 1 is provided with airduct groove 3; Also be provided with glue post 4 on the casing 1 near airduct groove 3, described airduct 2 is fin 21 with holes or slick U-shaped pipe for outer wall is fixed with, and airduct 2 is through in the airduct groove 3 of above-mentioned glue fixing on sound box 1.
As shown in Figure 1, the audio amplifier that the embodiment of the invention provides comprises casing 1 and the airduct groove 3 that is arranged in the casing 1, is provided with five glue posts 4 near the casing 1 of airduct groove 3.
As shown in Figure 2, airduct 2 is the U-shaped pipe, is fixed with a plurality of fins 21 at airduct 2 tube walls (comprising sidewall and base wall); For example, sidewall is provided with four fins 21, is provided with a fin 21 in airduct 2 base wall; These five fins 21 are arranged on same plane, behind glue on fin 21 and the glue post 4 junction points, because the involatile constituent of glue is identical with the composition of casing 1 and airduct 2; After treating that the glue solidifies, glue that solidifies and casing 1, airduct 2 bonding being integral.
As shown in Figure 3, there is not fin on airduct 2 sidewalls, be slick U-shaped pipe; Airduct 2 is put into airduct groove 3, clicking and entering glue to glue post 4 places again, and suitably increasing the consumption of glue; Make glue be spilled on the sidewall of airduct 2, thereby realize that airduct 2 is fixedly connected with casing 1.
Because above-mentioned audio amplifier air duct gluing method adopts above-mentioned glue; Make that audio amplifier air duct gluing method only needs airduct 2 is positioned in the airduct groove 3 that is provided with on the sound box 1; Glue is treated that the glue solidifies and is got final product on the point; Need not heat energy is that high temperature scalds the glue post, thereby simplifies audio amplifier air duct gluing method, has reduced the production cost of audio amplifier; Meanwhile; Because the glue involatile constituent is consistent with the composition of sound box 1, airduct 2; When the waste product of audio amplifier, airduct in recycling once more, need not to waste time and energy and remove glue earlier, and the waste product of recycling is free from foreign meter; Save production cost, improved the production efficiency and the product qualified rate of enterprise; The solid colour of glue involatile constituent and sound box 1, airduct 2 has been eliminated the vestige of audio amplifier obvious glue in the past, makes airduct 2 and sound box 1 reach the effect that merges fully, has strengthened the attractive in appearance of product.
