SPC:stoneplasticomposite, European and American countries call it RVP (rigidvinylplank) and rigid plastic floor.
The button-type SPC stone-plastic floor is in the stage of active promotion and rapid development in the domestic and foreign markets.
SPC floor size mainly includes: 1210*150, 1210*181, 203*1219, 178*1219, 152*1219 (unit mm)
Plastic floor construction.
PVC floor ingredients: PVC resin powder, stone powder, plasticizer, stabilizer, carbon black, the main components are PVC, stone powder.
The plastic floor is composed of PVC-based color film decorative paper, wear-resistant layer and UV coating from the bottom to the surface.
Stone plastic floor SPC:
Stone plastic floor SPC is a new type of environmentally friendly floor based on high-tech development. It has the characteristics of zero formaldehyde, mildew proof, moisture proof, fireproof, insect proof, and simple installation. SPC floor is a PVC base material composed of extruder and t-die. The PVC wear-resistant layer, PVC color film and PVC material are heated and embossed at one time with a three-roll or four-roll calender, respectively. The process is simple and can be bonded without glue. The invention adopts an environment-friendly formula, does not contain harmful substances such as heavy metals, phthalates, methanol, etc., and complies with EN14372, EN649-2011, IEC62321, GB4085-83 standards. It is very popular in developed countries in Europe and America and the Asia-Pacific market. With its excellent stability and durability, the stone plastic floor not only solves the problem of damp, deformation and decay of solid wood floors, but also solves the formaldehyde problem of other decorative materials. There are many colors and patterns to choose from, which are suitable for indoor furniture, hotels, hospitals, department stores and other public places.
SPC floor shrinkage rate: ≤1‰ (after tempering), ≤2.5‰ (before tempering), (shrinkage rate test standard: 80℃, 6 hours)
SPC floor density: 1.9~2 tons/cubic meter;
Advantages of SPC floor: The physical index of SPC floor is stable and reliable, and the chemical index conforms to international national standards;
Disadvantages of SPC floor: SPC floor has high density, heavy weight and high transportation cost
Compared with LVT and WPC floor, the processing and manufacturing technology of SPC floor is simple.
The advantages of SPC environmental protection floor:
SPC floor is a new type of environmentally friendly composite product with the following advantages:
(1) Waterproof and moisture-proof. It fundamentally solves the problem that wood products are easily rotten and swelled and deformed after absorbing water in humid and multi-water environments, and can be used in environments where traditional wood products cannot be used;
(2) Insect and termite prevention, effectively prevent insect harassment and prolong service life;
(3) Colorful, many colors to choose from. Not only does it have a natural wood texture and wood texture, but you can also customize the color you want according to your personality.
(4) Strong plasticity, which can easily realize personalized modeling and fully reflect individual style;
(5) Environmental protection, non-polluting, non-polluting and recyclable. The product does not contain benzene and formaldehyde, and is an environmentally friendly product. It can be recycled and reused, which greatly saves the amount of wood. It is suitable for the national policy of sustainable development and benefits the society;
(6) High fire performance. Can be effectively flame retardant, the fire rating reaches B1 level, the fire is extinguished, and no toxic gas is produced
(7) Good workability, can be ordered, can be planed, can be sawdust, can be drilled, and the surface can be painted
(8) The installation is simple, the construction is convenient, no complicated construction technology is required, and the installation time and cost are saved
(9) No cracking, no swelling, no deformation, no maintenance, easy to clean, saving later maintenance costs;
(10) The sound absorption effect is good, the energy saving is good, and the indoor energy saving is more than 30%;
(11) Compared with LVT\WPC floor, SPC floor has low investment cost, quick effect, less labor, less labor intensity and clean environment.
SPC floor production technology:
Procedure: 1.
Automatic metering according to the proportion of raw materials → high-speed mixer hot mixing (hot mixing temperature: 125 ℃, function.
Mix all kinds of materials evenly, remove the moisture in the material) → enter the cold mixing (cool the material)
To prevent discoloration of agglomeration, cold mixing temperature: 55 ℃. → Cool and mix the material uniformly;
Step 2: Extrusion.
Add twin-screw extruder, heat and extrude → enter the sheet die for extrusion and forming, and form the sheet.
The material passes through a four-roll calender, and the thickness of the substrate is fixed → color film paste → wear-resistant layer paste → cooling → cutting;
The third step: UV tempering.
Surface UV → tempering (tempering hot water temperature: 80~120℃; cold water temperature: 10℃)
Process 4: grooving + packaging.
Cutting→grooving, trimming, chamfering→checking→packaging.
