Description
Technical field
The present invention relates to a kind of production technology of plastic floor, specifically relate to a kind of hot pressing combination process of PVC multi-layer composite floor.
Background technology
PVC multi-layer composite floor enters Chinese market at the beginning of 21 century, at southeastern coast and flourishing city ever more popular.PVC multi-layer composite floor is floor the most frequently used, the most universal in semi-rigid floor.Due to the superior performance of PVC multi-layer composite floor, attractive in appearance mat formation effect and outstanding Environmental Role, generally instead of ceramic tile and wood floors in developed country, become the first-selection of surface decoration materials.
Usually, need in PVC multi-layer composite floor production process die-filling through the folded material of sheet material, manually push away mould and enter flat-bed press, heating pressurize, production process such as cooling pressurize, depanning discharging etc.Separate unit press is adopted to carry out heating pressurize and cooling pressurize molding production process during current production PVC multi-layer composite floor, namely floor high pressure (being generally greater than 0.8MPa) is steam heated to technological requirement temperature on same press to carry out heat-insulation pressure keeping and to drain after 45 minutes steam, then passes into cooling water pressurize and be cooled to room temperature (cooling procedure generally needs 25 minutes).There are the following problems for this process:
(1) energy resource consumption is large, and being heated to more than 115 DEG C, to be cooled to room temperature be again a production cycle, obviously there is energy waste;
(2) production cycle is long, and a hot-forming cycle at least needs 70 minutes;
(3) adopt high pressure steam heating insulation, during insulation, constant temperature effect is poor, there will be instantaneous temperature peak value (term: punching temperature) and makes the variable color of color printing fabric, make product rejection, therefore have a strong impact on product percent of pass between soak;
(4) equipment failure rate is high, thus increases maintenance of equipment expense;
(5) at the die-filling folded material of workman with push away in mold process and often make template be shifted, product quality is had a strong impact on.And the labour intensity of press setter is large, efficiency is low.Therefore the development bottleneck of PVC sheet composite floor board manufacturing enterprise is become.
CN104057567A proposes a kind of PVC board production technology, heating pressurization and cooling pressing technology is separated, and avoiding the very long stand-by period from being heated to cool, decreasing the energy waste caused because heating cooling repeatedly simultaneously.But its hot press technological temperature is set as 140 ~ 160 DEG C, and the operating pressure of hot press and cold press is all set between 18 ~ 20MPa.Temperature high pressure is high, both causes high energy consumption, makes again technical process restive, unstable product quality, and production cost improves.
Summary of the invention
The object of the invention is to avoid above-mentioned the deficiencies in the prior art, propose a kind of hot pressing combination process of PVC multi-layer composite floor, this combination process is rationally controlled, constant product quality, quality high-quality, energy consumption significantly reduces, production efficiency is high, and production cost is low.
The technical scheme that technical solution problem of the present invention is taked is, a kind of PVC multi-layer composite floor hot pressing combination process, comprises and mats formation, carries, hot pressing, pushes, colds pressing and mould unloading step, particularly:
(1) mat formation: at station of mating formation, the PVC sheet of template and difference in functionality is overlayed in the carrier of band positioning function;
(2) carry: be delivered in hot press by completing the carrier of mating formation;
(3) hot pressing: hot press adopts conduction oil loop heating system heated constant temperature hot pressing to each PVC sheet interlayer to be mutually bonded and is integrated;
(4) push: by automatic hydraulic module driving machine, carrier is shifted onto in the cold press of same level position;
(5) cold pressing: cold press is colded pressing and shaped to room temperature by water quench;
(6) mould unloading: carrier is pulled out cold press by automatically responding to drawing die forming machine, conveying is back to station of mating formation, and mould unloading also enters next round and mats formation.
As preferably, in described heat-press step, the hot pressing of described hot press adopts continuous print two sections pressurization.
As preferably, in described cold pressing step, colding pressing of described cold press adopts continuous print three sections pressurization.
As further preferred, described hot press processing parameter setting is hot pressing temperature 115 ~ 139.8 DEG C, and first paragraph pressure is 2 ~ 3MPa, and the time is 10 ~ 15 minutes, and second segment pressure is 3 ~ 7MPa, and the time is 20 ~ 30 minutes.
As further preferred, described cold press processing parameter setting is first paragraph pressure is 5 ~ 7MPa, and the time is 3 minutes, obstructed cooling water; Second segment pressure is 7 ~ 10MPa, and the time is 5 ~ 10 minutes, and second segment starts logical cooling water and maintain inlet channel pressure to be no less than 0.3MPa; 3rd section of pressure is 10 ~ 17MPa, and the time is 7 ~ 10 minutes, continues logical cooling water and to maintain inlet channel pressure constant.
The present invention adopts the carrier of band positioner, the PVC sheet of difference in functionality and template are overlayed in the carrier of band positioner, then carrier is delivered to hot press, the bed of material aligns with the coincidence of template and carrier aligns with platen-press heating plate, solve at the die-filling folded material of workman and push away in mold process the problem occurring that template is shifted, thus greatly reducing the product quality problem because registration brings not.In the present invention, hot pressing is carried out respectively with colding pressing in two press, avoids same press and repeatedly heats the energy waste cooling and cause, shorten the pressing process time; Especially the hot pressing of hot press adopts continuous print two sections pressurization, colding pressing of cold press adopts continuous print three sections pressurization, and in the setting of technological parameter, hot pressing temperature is low, be only 115 ~ 139.8 DEG C, during hot pressing each section pressure and when colding pressing the pressure of each section all greatly reduce, recombination process energy consumption is reduced greatly; Hot press have employed conduction oil loop heating system heating and thermal insulation, avoids the instantaneous temperature peak value that Steam Heating produces in constant temperature.Therefore, present invention process process stabilization is controlled, and product percent of pass greatly improves, and close to 99.9%, excellent product quality is stablized.Apparent realizing the advantage in high-quality, efficient and low consumption etc. for existing production technology.
