Calcium zinc stabilizer formula system is applied in resin expanded product in the present invention, uses hollow low foaming knot Skin production technology, it is high to stabilizer heat stabilizing system, lubricating system requirement, fully studied to all calcium zinc raw material mechanisms of action On the basis of grasp, formula system framework is redesigned.In heat stabilizing system design, using beta-diketon zinc and ST-220/ Used as core stable agent, be aided with phosphite ester and zinc acetylacetonate carries out stable regulation to F210, uses calcium stearate and stearic acid Zinc improves formula plasticizing capacity, and Related product is formulated consumption and calculates by accurate Theory and practical proof, after emphasis solves transfer Second time of foaming, mould zinc burn problem and meet the satisfaction requirement of product associated materials performance.In lubricating system design, using G60 Inner , used as core lubricant, being aided with OPE carries out inside and outside sliding collaboration, and the system must agree with for lubrication prescription and the outer lubrication prescription of PE waxes Resin expanded door long-term production stability, in the case where release property is ensured, reduces and separates out, and improves product stability and production week Phase.Calcium stearate and zinc stearate adjust plasticizing effect in passing through formula in foaming process, make do not influenceing the feelings of gas release Improve melt strength under condition, it is to avoid occur foaming doors surface crater, by adjust AC foam dosage and sodium bicarbonate content, regulation produce Product rice proportion and expansion ratio, it is ensured that product meets use requirement.
It is whole due to the difference of calcium zinc formula system and traditional lead salt system in terms of technology controlling and process in preparation technology Change production technology has specific technique matched from batch mixing-extrusion-later stage transfer film transfer, by technical research team Grope tackling key problem, analyzed in the main points of processes control such as each operation operation mechanism and temperature by formula each component, formulated a set of It is adapted to the technology controlling and process route of the product.According to the proterties of different material, physical characteristic, preformed in formula in terms of mixing procedure Change the key parameters such as requirement etc., the mixed mixing time of adjustment heat, improve preplasticizing effect.The morphogenetic change of material during heat is mixed Change：(1) apparent density for being compacted usual polyvinyl chloride resin is only 0.45~0.55g/ml.Due to phase mutual friction in high-speed mixer The frictional heat of generation, makes temperature of charge constantly rise, and PVC granule and other components are constantly interpenetrated, and PVC particle surfaces are gradually The various auxiliary agents such as Vapor recovery unit agent and molten lubricant etc., making the apparent density of compound can increase to 0.58~0.65g/ ml.(2) in high-speed mixer, each component can not only reach good mechanical mixture to homogenizing, also can obtain good between each component Stable dispersion.As temperature is constantly raised, PVC particles can constantly Vapor recovery unit agent, lubricant etc., gradually wrapped by each component Cover, when temperature rises to 110~118 DEG C, the dry mixed powder of uniform stabilization can be formed.(3) hydrofuge：When temperature of charge rises to 100 DEG C During left and right, the moisture that is included in resin and adjuvant component and other volatile substances are easy to remove, it is to avoid in extrusion type Bubble and defect are produced during material.(4) pregelatinized：The gelation of PVC refers to that resin progressively melts modeling in process Change, then recrystallization forms the process of network morphology structure, during high speed hot mixing, it is seen that the existing particle of polyvinyl chloride resin Refinement, the metamorphosis of uniform particle sizes, show again density increase, partial gelation the characteristics of.Therefore PVC material high-speed heat is mixed Conjunction process, is also the process of polyvinyl chloride resin homogenization, densification and partial gelation, though material gelation is not the main mesh of batch mixing , but in mixed process, there is gelation in existing part PVC particles.There are the small particles of large surface area, be vulnerable to larger Friction, reaches gelation state, shows similar transparence, and little particle is gradually melted at relatively high temperatures, is flocked together, Become larger particle, the PVC of surface gelling can be very good to absorb various auxiliary agents, finally give our common homogeneity With the preferable dry blend of mainstream property.(5) influence of the mixing temperature to mixture performance：The mixing temperature of material is influence dry blend One of most important factor of performance, mixture temperature be less than 80 DEG C when, material it is closely knit closely knit mainly by mechanical force, make each group subpackage It is trapped among PVC particle peripheries.When temperature is to higher than polyvinyl chloride resin glass transition temperature Tg (about 80 DEG C), PVC granule starts to soften, and inhales Other components are received, it is gradually closely knit, when temperature rises to 110~120 DEG C, less particle gradually gel in PVC particles, we pass through Feedstock property design studies, at 115-118 DEG C, the ecological transfer door formula compounding effect of calcium zinc is optimal, dry blend for temperature Pregelatinized degree highest.(6) incorporation time influence：Compacting, homogenizing, partial gelation mistake that material experiences in mixed process Journey, is required to certain hour completion.The extension of mixing time contributes to stabilizer and other additives to be more uniformly diffused into In resin, further to improve material stability and uniformity coefficient.Rule of thumb, incorporation time is extremely in high-speed mixer for material Less between 300~420 seconds, uniform quality, the dry blend of dry good fluidity can be just obtained.(7) feeding quantity in high-speed mixer Influence：The feeding quantity selected in high-speed mixer, should be able to be conducive to production efficiency on the premise of mixed material quality is ensured Improve.Too small per batch materials inventory, such as volume of material is only less than the 50% of high-speed mixer, and material seethes poor, generation Frictional heat it is low, temperature rise is slow, and time-consuming, reaches default mixing temperature and about want more than 15min, while also the mixing of influence material is It is even.Conversely, inventory is excessive, motor load is too high, and the speed of mainshaft declines, and equally influence material seethes situation and batch mixing matter Amount, programming rate is also no longer significantly improved.Usual feeding quantity is in mixer volume 60%~80%, and mixed effect is preferable.This Batch mixing amount accounts for the 65%-68% of pot volume in application, and preferably, sheet material production is steady for the pregelatinized effect of calcium zinc formula compound It is fixed.(8) the mixed flow deflector of heat will directly affect material and be seethed in pot in semiellipse cambered surface, therefore flow deflector angle in batch mixing pot Effect, so as to influence matter homogenizing and pregelatinized effect, by design studies, excessively middle flow deflector side of device itself should be apart from pot Wall 1-23-5cm is a width of preferably, and now material seethes best results in pot.
By reducing first three area's temperature (temperature control is at 150 ± 10 DEG C) in terms of expressing technique, discharging speed is controlled (0.6 ± 0.2m/min) finds out the modes such as rational production capacity interval, the problems such as preventing zinc and burn, and reduces to a certain extent The generation of precipitate, improves production stability.Extrude control technology in the present invention to be mainly reflected in temperature control, on the one hand To suppress foaming too early in early stage, while cylinder area temperature will match with calcium zinc formula feature, while by investigation and comparison, calcium zinc Using the positive setting of temperature, than using, temperature parabola is set ecological door extrusion foaming technique and reverse setting of temperature discharges uniformly Degree, surface skining effect is even more ideal.
Transfer temperature is especially paid close attention in terms of transfer printing process, in the situation of the fully change in size that research second time of foaming causes Under, rational transfer temperature control interval is set, to transfer speed (sheet material is controlled in 3-5m/min), (control of platen pressure scale System is in 39.2mm), the link such as preheating temperature (185 ± 5 DEG C) is strictly controlled.
Compared with prior art, the present invention provide use calcium zinc stabilizer resin expanded transfer door, calcium zinc-base material with Transfer printing process all meets environment-friendly materials requirement, and base material is free of heavy metal, and transfer materials are free of formaldehyde；Anti-corrosion, protection against the tide, Anti-moth-eating, It is indeformable, due to main material polyvinyl chloride self performance used, influenceed smaller by soda acid；Water absorption rate is only 0.5%；It is effectively anti- Only damage by worms.It is highly suitable for the environment of southern humidity.Processing install convenient, sheet material inside use hollow structure and core layer foaming skill Art, makes the density of foamed products close to timber.The xyloid processing request of class, the installation than wooden door is more quick, is not required to nail Nail, smear putty, brush paint etc. traditional work mode, factory normalization production, Digit Control Machine Tool milling hinge, lockhole, decorated dormer Hole, dimensional standard is accurate, it is ensured that overall tight during in-site installation.Using bulk-breaking modular construction, it is readily transported, in-site installation side Just, it is to avoid numerous and diverse at the scene manual processing and making process, the road of batch production pipelining is walked, improves the making of door Installation effectiveness.Manufacturing process variation, without professional, machining tool highly versatile used.
