The purpose of the present invention can be realized by following technical proposal: a kind of without the process of preparing of light PVC film in shadow,
Comprise the following steps:
(1), dispensing: carry out weighing dispensing by metering ratio by each raw material；
The formula of described raw material is by weight:
(2), mix and blend: the material input homogenizer that will configure in step (1), elder generation's stirring at low speed after 60 seconds again
Change into high-speed stirred appropriate time, carry out stirring at low speed the most again, make material form homogeneous dispergated mixed powder；This mixes
The measured temperature closing powder body is 100 DEG C to 110 DEG C；
(3), refining moulds: homogeneous dispergated mixed powder enters banbury automatically by pipeline, under weight pressure and turn
Son refines to mould further under shearing and plastifies into bulk body, until not having granular fecula during discharge in bulk body；
(4), mill: bulk body is delivered to first and rolls turbine, first roll in turbine relative to operating running roller material is entered one
Step mill fluxing becomes homogeneous phase, and then material is sent into extruding filter by belt conveyor, is sheared plasticizing further by screw rod, and
Filtered out the foreign body in material by the die head being mounted with secondary filter net, the most again material is expressed into second and rolls turbine, the
Two roll the running roller of two relative operatings in turbine by material cutting and obtains the most homogenous plasticized；
(5), masking: the material plastified is by tape transport to the calender being made up of four pressure rollers, and material is by four
The roll-in successively of individual pressure roller, tentatively draws required film material by the spacing and stretching speed ratio controlling each roller, and caudacoria material is through drawing
Wheel stretching further and plasticizing, then after decorative pattern iron tyre with rubber wheel embossing, shape for the first time；Then film material entrance temperature refining wheel is released
Putting internal stress, the most cooled wheel gradually cools down, and is then passed through both sides all to cutting edge, becomes finally by automatic rolling device
Volume.
Above-mentioned without shadow in light PVC film process of preparing in, in the raw material of step (1), described age resister
For epoxy fat, described PVC resin powder is the K value powder in 70 to 75 types.
Above-mentioned without shadow in light PVC film process of preparing in, in the raw material of step (1), described environmental protection plasticising
Agent is phthalic acid dioctyl decyl ester.
Above-mentioned without shadow in light PVC film process of preparing in, in the raw material of step (1), described calcium carbonate adds
The mesh number added is 6000 mesh.Utilize calcium carbonate can change the viscosity in film processing and in finished product folding.
Above-mentioned without shadow in light PVC film process of preparing in, in step (4), described first rolls the work of turbine
Being 180 DEG C ± 5 DEG C as temperature, the operating temperature of described extruding filter is 185 ± 5 DEG C, and described second rolls the work temperature of turbine
Degree is 170 ± 5 DEG C.

Above-mentioned without shadow in light PVC film process of preparing in, in step (5), in described calender, a roller
Operating temperature be 185 ± 5 DEG C, the operating temperature of No. two rollers is 182 ± 5 DEG C, and the operating temperature of No. three rollers is 175 ± 5 DEG C, four
The operating temperature of number roller is 150 ± 5 DEG C；Described rubber wheel, temperature refining wheel and cooling wheel are water cooling temperature.
Compared with prior art, in this nothing shadow, its main excellent results of the process of preparing of light PVC film is:
1, product has done compositional refinements on the basis of original conventional products and production technology adjusts, and eliminates PVC film normal
The flaw phenomenons such as the scenery with hills and waters stricture of vagina of appearance, the black stricture of vagina of wrinkle.
2, make the light transmission of product strengthen by the adjustment of dispensing proportioning, and illumination flexibility is the most dazzling.
Use high density filter screen instead when 3, producing, prevent black, yellow some distributive law of product, it is to avoid the product of cold speckle impurity etc.
Raw, simultaneously by increasing production temperature, strengthen plasticizing, slow down, reduce the generation of shrinkage factor and drag line, make product the most beautiful
Seeing, internally beating lamp decoration improves serviceability and effect.
4, it is significantly stronger than conventional interior light product, so deeply being favored by user, along with lamp because of performance and the effect of product
The development in decorations market and upgrading, the lamp decoration product of high-quality will be becoming increasingly popular, provide opportunity for new product.
