Abstract
The invention discloses a PVC sheet of an artificial marble or an artificial wood-grain board as well as a manufacturing method of the PVC sheet and processing equipment, which are used for improving reality degree of the PVC sheet of the artificial marble or the artificial wood-grain board. The PVC sheet comprises a PVC base material, wherein a plurality of texture regions are distributed on the PVC base material from inside to outside. Through the texture regions, the inner part and the end surface of the PVC base material have grains consistent with those of the surface, and therefore, the effects of the artificial marble or the artificial wood-grain board can be completely simulated; and when the sheet is cracked or the end surface of the sheet is exposed, appearance which is similar to that of the diamond or the wood-grain board can be still kept, and therefore post-treatment or maintenance is relatively convenient.
Description
Technical field
The present invention relates to finishing, decorative materials technology are and in particular to arrive the PVC of a kind of parian or imitation wood card
Sheet material and preparation method thereof and process equipment.
Background technology
Natural marble or grain board all belong to high-quality house decorative material, and its texture is unfolded attractive in appearance, natural and tripping, has
Ornamental well, its relative cost is also higher.The PVC sheet of parian or imitation wood card is with PVC and calcium powder as base
Material, extrusion molding after mixing, then surface imprints marble grain by techniques such as thermal transfers or grain pattern forms, and replaces sky
So marble, grain board are widely used in various inner wall of building decorations, can reach the effect mixed the spurious with the genuine, and its cost is far below
Natural marble or grain board.
But the PVC sheet of existing parian or imitation wood card is all surface transfer, such as water transfer, thermal transfer etc.,
Only have sheet surface textured, the end face of sheet material and inside are all pure color.When PVC sheet rupture or end face expose, energy one
Eye is seen to be PVC sheet, rather than natural marble or grain board, and this can affect the overall perception of inner wall decoration.
Content of the invention
In order to improve the degree true to nature of the PVC sheet of parian or imitation wood card, the invention provides one kind is in sheet material

Specific embodiment
The invention will be further described with embodiment below in conjunction with the accompanying drawings.
In embodiment, as shown in figure 1, the PVC sheet of a kind of parian or imitation wood card, including PVC base 1, described
PVC base 1 is distributed with some texture area 2 from the inside to the outside.The texture area 2 of the present embodiment makes the inside of PVC base 1, end face tool
There is the lines consistent with surface, almost can imitate the effect of marble or grain board completely, when sheet fractures or end face expose
The outward appearance approximate with marble or grain board, post processing or maintenance all relatively convenients still can be kept.
In embodiment, as shown in figure 1, every described texture area 2 includes at least two striated bands, adjacent described striated band it
Between color gradient.The texture area 2 of this kind of form is more like with natural marble, grain board, and vision perception is preferably also.
In embodiment, as shown in Figure 2, Figure 3, Figure 4, the preparation method of the PVC sheet of a kind of parian or imitation wood card,
By PVC raw material extrusion moulding, extrusion moulding includes heating, melting, homogenization process to described PVC base 1 successively, in described homogenizing mistake
Journey adds the pigment for forming texture area 2 in PVC raw material.During extrusion moulding, heating process is used for PVC raw material
Preheated, be compacted and conveyed；Melting process makes PVC raw material be compacted further and plastify, and makes the air being enclosed in PVC raw material
It is pressed back into discharging at charge door, and improve the heat-conductive characteristic of plastics；Homogenization process plastifies and homogenization further, makes PVC former
Materials quantitative, level pressure, constant temperature ground are from head extrusion.The arrangement adding pigment is arranged in homogenization process, can reach certain
Mixed effect, is avoided that pigment transition mixes again, makes texture area 2 excessively light excessively shallow.In addition, also can by change pigment color,
Addition is realizing parian or the imitation wood card of different texture.
In embodiment, as shown in Figure 2, Figure 3, Figure 4, a kind of PVC piece for realizing above-mentioned parian or imitation wood card
The process equipment of the preparation method of material, including the main extruder 3 for PVC base 1 extrusion moulding, at least two are used for adding face
The auxiliary extruder of one-level 4 of material, the corresponding heating of described main extruder 3, melting, homogenization process are respectively equipped with bringing-up section, melt zone, all
Change section, the discharging opening of the auxiliary extruder 4 of described one-level is communicated on the diverse location of described main extruder 3 homogenizing zone.The present embodiment
Pigment by the auxiliary extruder of one-level 4 complete add, for ensure pigment add stability, and then ensure parian or
Imitation wood card outward appearance and the concordance of inner vein；The auxiliary extruder of one-level 4 being arranged on diverse location, reflects different stricture of vaginas
The depth difference of reason area 2 color.In order that parian or imitation wood card are more true to nature, as a rule, need to be equipped with 3 ~ 4 even
More auxiliary extruders of one-level 4.
In embodiment, as shown in Figure 2, Figure 3, Figure 4, also include two grades of auxiliary extruders 5, the auxiliary extruder 4 of described one-level with
Sample is provided with bringing-up section, melt zone, homogenizing zone, and described two grades of auxiliary extruder 5 discharging openings are communicated to the equal of the auxiliary extruder of described one-level 4
Change in section.Two grades of auxiliary extruders 5 of the present embodiment are used for making different striated bands on same texture area 2, and striated band
Between color gradient transition, to reach more life-like technique effect.
In embodiment, as shown in Figure 2, Figure 3, Figure 4, described main extruder 3 is double screw extruder, the auxiliary extrusion of described one-level
4, two grades of auxiliary extruders 5 of machine are single screw extrusion machine, and it is equal that its screw rod is equipped with screw rod bringing-up section L1, screw rod melt zone L2, screw rod
Change section L3；Described main extruder 3, the screw rod of 4, two grades of auxiliary extruders 5 of the auxiliary extruder of one-level are provided with servomotor or stepping electricity
Machine, the rotating speed of described all servomotors or motor is controlled by same main frame 6.The present embodiment main frame 6 is PLC or PC master
Machine, controls servomotor or motor, each auxiliary extruder 4 of one-level or two grades of auxiliary extruders 5 to realize not according to pre-booking process
With rotating speed so that the shade of texture area 2 replaces；Change different programs, just can manufacture different products.Additionally, giving birth to
Easy to adjust during product, the work of configuration different colours pigment especially in process parameter test, formulation process, can be save
Make, save a large amount of manpower and materials, and precise control can be accomplished, operation is repeatable high.
In embodiment, the discharging opening of the auxiliary extruder 4 of described one-level is arranged on the position away from main extruder 3 die orifice 20 ~ 60cm.
The discharging opening of the auxiliary extruder of one-level 4 of the present embodiment can be close proximity to the die orifice of main extruder 3, to prevent pigment by main extruder
3 mixing；And keep the distance of 20 ~ 60cm to can guarantee that certain stirring immixture to ensure texture area 2 in PVC base 1
It is evenly distributed from the inside to the outside.
Obviously, the above embodiment of the present invention is intended to be merely illustrative of the present example, and not to the present invention
Embodiment restriction.For those of ordinary skill in the field, can also make on the basis of the above description
The change of other multi-forms or variation.There is no need to poor example is given to all of embodiment.And these belong to this
The obvious change that the connotation of invention is amplified out or variation still fall within protection scope of the present invention.
