Description
Technical field
The present invention relates to fire-proof smoke-proof sound insulating seal bar production technology, particularly relate to a kind of novel working method of fire-proof smoke-proof sound insulating seal bar.
Background technology
Along with the raising that the sealing development of industry and fire-proof doors and windows require, fire-proof smoke-proof sealed strip plays as increasing in fire proof seal, Smoke prevention, sound insulation, dust-proof, warming and energy-conservation effect in fire-proof doors and windows.And general sealed strip is extruded by materials such as PVC, modified PVC, Ethylene Propylene Terpolymer, elastic body sealing strip (TPV, TPE, TPR), silica gel and is formed.But above-mentioned materials can not play a role on fire-proof doors and windows, even when presence of fire, do not have the fireproofing function in isolation smog and expansion plugging space, can the intensity of a fire be increased on the contrary and discharge dense smoke and toxic gas, cause secondary disaster, be therefore restricted in fire-proof doors and windows uses.
The production process of existing fire proof sealing strip is complicated, require high to the size of component and cooperation, cause fire proof sealing strip manufacturing cost used at present high, quality is unstable, installs complicated, even the application of some occasions has limitation, tracing it to its cause is caused by traditional working method, and in general, sealed strip is by cushion compound or bubble circle, then manual assembly enters in the T-shaped of doorframe or U-type groove, only plays the effect of single-side sealing.
This case is by innovating the analysis of above technology and the experience of accumulation in producing again, novel coextrusion process is adopted to make base plate and the soft wing two parts of fire-proof smoke-proof sound insulating seal bar hard, with mould and two extrusion lines, disposablely complete combination, the work such as rubberizing, cutting, packaging, produce line and produce finished product from the beginning to the end; Need it is important to point out that, the key implementing this case technology is temperature, owing to needing by the Material cladding of two portions differing temps characteristic together, and the processing temperature of this two-part material itself is just different separately, especially the flexible PVC fire retardant material with NBR, should process about 120 DEG C time, and the base plate of hard needs to process when about 160 DEG C.
Thus, for above aspect, need effectively to innovate prior art.
Summary of the invention
For the defect of traditional diamond-making technique, the invention provides a kind of novel working method making the formula reasonably optimizing of two portion of material and a mould structure output bas line mechanization production fire-proof smoke-proof sound insulating seal bar of employing complexity.
For achieving the above object, the present invention is by the following technical solutions:
A novel working method for fire-proof smoke-proof sound insulating seal bar, is made up of following steps:
(1) first, the particle of preparation two part raw materials, i.e. hard floor and soft wing material: hard floor wherein adopts PVC powder to be that 100phr, DOP softening agent is less than or equal to that 4 phr, CPE toughner are 8 phr, calcium powder CaCO3 is less than or equal to 20 phr, mix successively with high speed mixer, when reaching 115 DEG C, put compound to the mixing of low speed cooling mixing machine, release when being cooled to 50 DEG C, form compound I;
The soft wing wherein adopts PVC powder to be that 100phr, DOP softening agent is more than or equal to that 90phr, NBR are 12phr, calcium powder CaCO3 is less than or equal to 10 phr, and fire retardant is 4phr; Mix successively with high speed mixer, when reaching 120 DEG C, putting compound to the mixing of low speed cooling mixing machine, releasing when being cooled to 50 DEG C, form compound II;
(2) adopt conical double-screw granulating equipment, will through step (1) each compound cooled, respectively 120-150 DEG C, be processed into particle under 5-20Mpa condition, hard floor wherein needs the hardness reaching shore 65-70D, and the soft wing wherein needs the hardness reaching shore 55-65A;
(3) then, prepare two Single screw extrusion equipment, add the particle of two parts respectively, connecting mold;
(4) arrange the temperature of two extrusion equipments, speed, the extrusion equipment for hard floor is set to 120 ~ 155 DEG C, and the extrusion equipment for the soft wing is set to 125 ~ 135 DEG C, and process velocity is 3-5M/min, and two partial particulate make finished product through mould;
Step (4) after, can be passed through vacuumize sizing, water cooling, air-dry dry, draw, stick double sticky tape after, blocked by auto counter cutting facility, vanning, packing;
Two Single screw extrusion equipment, wherein one can be set to main frame, another two as side feeder apparatus.
The beneficial effect of the novel working method of fire-proof smoke-proof sound insulating seal bar of the present invention is:
(1) coordinated by the reasonably optimizing of hard floor, this bi-material of soft wing formula, the soft wing and base plate adhesion can be guaranteed firmly, and make the size of product and outward appearance reach the flatness requirement of drawing;
(2) high, the cost of labor of efficiency reduces, good product quality and stable, and traditional method is complex steps then, and product also exists fitted position matching problem, and difficult quality is stablized;
(3) because traditional method can only make product produce the sealing in a face in the malleation side of door and window or side, therefore, the effect every cigarette and sound insulation is poor, and this programme is just having, sealing while face, two, side, therefore greatly improves every cigarette deadening;
(4), in addition, due to the use of novel working method, the new contour structures (wing as soft in both sides, the monolateral soft wing etc.) that Conventional processing methods cannot be implemented can be produced, and traditional method only can make the film in mid-way.
