Description
Technical field
The present invention relates to a kind of composite floor board, more particularly to a kind of lightweight VCP floor and preparation method thereof.
Background technology
VCP floors in the market are mainly by groups such as wearing layer, color film, PVC base, VCP base materials, backing materials
Into global density is in 1.3-1.4g/cm3Between, processor is miscellaneous, and production VCP floors first have to produce PVC base, then with
Wearing layer, color film carry out hot Combined Processing, then carry out surface UV, punching molding, fit, cold pressing, cutting, operation of slotting, entirely
Time, manpower and the resource consumed by production process all compares many, and complex procedures cause the yield rate of production link to reduce；Due to
Current VCP floors belong to multilamellar and meet floor, therefore, also undesirable in terms of THICKNESS CONTROL, the accumulation between each level is public
Difference often exceeds critical field, and general deviation is between 0.15-0.25mm；Further, since current VCP floors top section
It is to be made up of for material of main part PVC, and upper strata layer of PVC, further through heat treatment destressing, the heat shrink rate on upper strata is than lower floor VCP
Little many of the shrinkage factor of base material, so floor is during use, heating warpage situation is than more serious.
The content of the invention
In order to solve the defect pointed out in prior art, the present invention provides a kind of lightweight VCP floor, and which has easily spelling
Connect, density is low, process is simple the advantages of.
The technical solution adopted for the present invention to solve the technical problems is：
A kind of lightweight VCP floor, the lightweight VCP floor are to be composited by color film, wearing layer, VCP base materials from top to bottom,
The main component of wearing layer is chlorinated polyethylene, and the raw material composition of wearing layer includes by percentage to the quality：Chlorinated polyethylene 64-
75%, environment-friendly plasticizer 15-20%, stabilizer 3-4%, precipitated calcium carbonate 7-12%；The raw material of VCP base materials is constituted with matter

The content of compound, wherein ground calcium carbonate is 55-75%.The optimum weight ratio of precipitated calcium carbonate and ground calcium carbonate is 3:7.
Preferably, the thickness of wearing layer is 0.1-0.6mm, the thickness of color film is 0.07mm, and the thickness of VCP base materials is 4-
5mm。
Preferably, the main component of the color film of printing is PVC, its raw material composition includes by percentage to the quality：PVC 97-
98%, Calcium Carbonate 1-2%, stabilizer 0.5-1%, processing aid 0.5-1%.
A kind of preparation method on described lightweight VCP floor, the method include layer of PVC processing, the processing of VCP base materials, laminating,
Cold pressing, surface UV processes and slot operation, mainly comprise the following steps：Wearing layer and the color film of printing make layer of PVC by heat is compound, and heat is multiple
The temperature of conjunction is 120-150 DEG C, minute time 10-20；Then by layer of PVC and VCP base material cold moudlings, temperature 23-25 DEG C, when
Between 12-36h.
Preferably, the method comprises the steps：
1st, the processing of layer of PVC：The wearing layer for preparing and the color film of printing are overlayed in the carrier of vulcanizing press, temperature
120-150 DEG C of degree setting, the demoulding after heat compound 10-20 minutes, the heat for completing wearing layer with the color film of printing are combined；
2nd, VCP base materials processing：Polrvinyl chloride, composite calcium carbonate, stabilizer, foaming agent are put in proportion mixed at a high speed
Close cylinder to be stirred, rotating speed 700-800 turns/min, and minute time 12-15, temperature is discarded to cooling when reaching 110-115 DEG C and stirs
Cylinder is mixed, 60 ± 5 DEG C are cooled to, and lubricant and processing aid is added through Screw Extrusion slice；
3rd, fit：After VCP base material completion of processing, constant temperature stands and carries out bonding process later in 24 hours, makes layer of PVC and VCP
Base material is fitted；
4th, cold pressing：Be immediately placed in after the completion of laminating cold press fit again it is strong to increase the laminating of layer of PVC and VCP base materials
Degree, cold pressing pressure 5-7MPa, temperature 23-25 DEG C, 12-36 hours of colding pressing；

6th, slot.
Preferably, heat is combined when making layer of PVC, the compound temperature of heat is 135-150 DEG C, minute time 16-18.
Compared with prior art, lightweight VCP floor of the invention has advantages below：
1st, lightweight VCP floor of the invention is mainly made up of wearing layer, color film, VCP base materials, and global density is in 0.95g/
cm3Left and right, greatly reduces mass area ratio, reduces also reducing cost of transportation while mass area ratio, is installing
The labor intensity of installation personnel is also reduced during floor；
2nd, when lightweight VCP floor is produced, PVC base need not be produced, wearing layer and color film can be carried out into heat directly multiple
Conjunction is processed, and hot recombination time is 10-15 minutes, is compared current VCP floors upper strata PVC heat recombination times and is reduced 60-75%,
The labor intensity of heat compound personnel is also mitigated while reducing energy consumption improve production efficiency, because the layer of PVC on VCP floors at present
The density of base material is 1.85g/cm3, the lightweight VCP floor of the present invention is without the need for PVC base；
3rd, directly need not carry out fitting after heat is compound, cold pressing treatment, UV process is carried out to surface again after colding pressing, then
Carry out cutting, slot, during this, save the operation of heat treatment destressing, and the operation of surface UV process is placed on and colds pressing it
Afterwards, the destruction when fitting, colding pressing to surface UV coating layer can be avoided, makes the glossiness and scratch resistance intensity of floor surface more preferable；
4th, as the composition structure on lightweight VCP floor is relatively simple, level is fewer, thus for gross thickness control ratio compared with
Ideal, maximum deviation are less than 0.07mm so that splicing floors are more smooth.
