Description
Technical field
The invention belongs to door and window fields, more particularly to a kind of production technology of door and window.
Background technology
In architectural decoration, people commonly use wooden door and fit up the room of oneself.But sound insulation, sealing property are not reached
Preferable effect, has a strong impact on the acoustic environment of people's private space.Particularly public place noise ratio is larger, with greater need for soundproof door
To equip with arms working space.
Existing Woodiness sound-proof door is most of to improve overall soundproof effect by increasing door body with the sealing of doorframe,
But door body often produces deformation in wet weather, now door body will weaken significantly with the sealing of doorframe, soundproof effect
Substantially reduce.
The content of the invention
It is an object of the invention to provide a kind of production technology of sound insulation tide gate, the production technology can prevent door body because of tide
Change and deform upon, and the soundproof effect of door body can be improved.
In order to achieve the above object, base case of the invention provides a kind of production technology of sound insulation tide gate, including such as
Lower step, is calculated with mass fraction：
A, making inner panel and outside plate：Timber is carried out into sawing according to preliminary dimension and shape and forms batten, then the chi according to needed for
It is very little to piece together a plurality of batten together, form inner panel and outside plate；
B, making puigging：Weigh 20 ~ 32 parts of carbon fiber, 48 ~ 52 parts of wood chip, 30 ~ 42 parts of acoustical cotton, by carbon fiber, wood chip and
Tabular is pressed into after acoustical cotton mixing；
C, making dehumidifying layer：Straw is crushed, weigh crushing after 42 ~ 48 parts of straw, then be able to will connect power supply heat transfer silk it is attached
And form netted on straw, be finally pressed into tabular；
D, making water accepting layer：A hollow thin plate is made, 50 ~ 54 parts of salt, 25 ~ 37 parts of flour is weighed, salt and flour are mixed
It is filled into thin plate after closing uniformly；
E, sizing：Puigging, dehumidifying layer and the water accepting layer that will be made are overlayed on inner panel successively, then outside plate is laid on into water suction
On layer, inner panel and outside plate are fixed by screw after extruding, form door body；
F, impregnation：It is 3min ~ 5min in 24% ~ 26% epoxy resin solution that door body described in step e impregnated in into concentration, so
Take out afterwards and door body is dried.
The beneficial effect of this base case is：
（1）Water accepting layer is filled into thin plate after being mixed using salt and flour, and salt and flour are respectively provided with water absorbing properties, work as humidity
Weather comes interim, and the steam that salt and flour will can enter in door body is concentrated and is absorbed to water accepting layer；
（2）Be attached to heat transfer silk on the straw of crushing by dehumidifying layer, after steam is absorbed by salt and flour, by heat transfer silk
Water vapour is formed after heating, water vapour from outside the end outflow door body of straw, so as to keep door body to dry, prevents door along straw
Body deforms；
（3）Puigging is made up of wood chip, cotton fiber fiber and acoustical cotton, and wood chip porosity is high, coordinates acoustical cotton, is greatly improved
To the absorptivity of sound, soundproof effect is good, and cotton fiber has certain supporting role, is prevented from wood chip and acoustical cotton stacking
It is blocking to cause wood chip and acoustical cotton in puigging to be uniformly distributed, influence soundproof effect；
（4）By water accepting layer, dehumidifying layer and puigging folder between the inner plate and the outer plate, it can be ensured that the rigidity of whole door body, play
The effect of sizing support；
（5）Make door body be immersed in epoxy resin solution to be dried after a period of time, epoxy resin can be made to be attached to door body table
Face, forms waterproofing membrane layer, and the steam that can be intercepted to a certain extent in air enters in door body, plays moisture-proof role.
Scheme two：Scheme is preferred based on this, the wood chip that the wood chip described in a is formed after being crushed using waste board material.
Using waste and old board making wood chip, the sound insulation moisture-proof function of door body is neither influenceed, timber resources has been saved again, reduced and be produced into
This.
Scheme three：Scheme is preferred based on this, and the thickness of inner panel and outside plate in a and e is 3.0mm ~ 8.0mm.It is thick
Spend for the inner panel and outer plate thickness of 3.0mm ~ 8.0mm are appropriate, the rigidity of door body can either be ensured, be unlikely to make whole door body again
Excessively thick and heavy or influence aesthetic property.
Scheme four：Scheme is preferred based on this, and drying in g is dried using dry kiln, and drying temperature is 75 DEG C ~
95 DEG C, furnace air flow velocity is 1.0m/s ~ 1.8m/s.Door body can be dried in batches with dry kiln, improve production effect
Rate.
Scheme five：This is preferred for scheme four, to the door body sprayed fire proofing coating formed in g, forms fireprotection layer.Fireprotection layer
The function of door body is increased, spreading for the intensity of a fire can be intercepted when fire occurs, be that the escape of people is raced against time.
Scheme six：This is preferred for scheme five, and the door body to being formed in g posts ornament materials, forms decorative layer.Decorative layer
The overall aesthetics of door body can be improved.
