◆The composition of the lock-type SPC stone plastic floor:
Floor composition: PVC resin powder, stone powder, plasticizer, stabilizer, carbon black, the main components are polyvinyl chloride and stone powder.
From bottom to surface, it is composed of PVC base color film decorative paper and wear layer and UV coating.
The lock type SPC stone plastic floor is a new environmentally-friendly floor developed based on high technology. It has zero formaldehyde, mildew proof, moisture proof, fireproof, insect proof and simple installation. SPC floor is extruded from the extruder with T-die to extrude the PVC substrate, and the three-roll or four-roll calender is used to respectively wear the PVC wear-resistant layer, PVC color film and PVC substrate, and heat-fit and emboss the product once. The process is simple, the fit is done by heat, and no glue is needed.
The lock-type SPC stone-plastic floor material uses an environmentally friendly formula and does not contain harmful substances such as heavy metals, phthalates, methanol, etc., and complies with EN14372, EN649-2011, IEC62321, and GB4085-83 standards. It is very popular in developed countries in Europe and America and in the Asia Pacific market.
With its excellent stability and durability, the stone-plastic floor not only solves the problem of moisture deformation and mildew of the solid wood floor, but also solves the formaldehyde problem of other decoration materials. It has a wide range of color patterns to choose from, suitable for indoor home improvement, hotels, hospitals, shopping malls and other public places.
Process for producing lock-type SPC stone-plastic floor:
Mixing----Automatic metering according to the ratio of raw materials→High-speed mixer hot mixing (hot mixing temperature: 125°C, the function is to mix all kinds of materials evenly, remove the moisture in the material)→ Enter cold mixing (cool the material to prevent agglomeration and discoloration, Cold mixing temperature: 55 ° C) → mixing the material by cooling;
Extrusion----Adding to the twin-screw extruder, heating and extruding → entering the sheet die extrusion molding, the formed sheet is subjected to four-roll calender, the substrate is thickened → the color film is applied → the wear layer is applied → the cooling → cutting;
UV tempering----Surface UV→tempering (tempering hot water temperature: 80~120°C; cold water temperature: 10°C)
Slitting and slotting----Slitting → Slotting, Trimming, Chamfering → Inspection → Packaging
