The invention discloses a stone
crystal floor and a manufacturing method thereof. A stone
crystal base plate and a stone
crystal decorative plate both are prepared from the following components: 50-80parts of
polyvinyl chloride resin, 0.5-10 parts of
chlorinated polyethylene, 100-150 parts of marble
powder, 0.5-8 parts of a
lubricant, 1-4 parts of a heat stabilizer, 0.5-2 parts of a plasticizingmodifier and 0.5-3 parts of an anti-aging agent. The stone crystal decorative plate is thermally laminated and composited to the stone
crystal base plate, and the outer surface of the stone crystal decorative plate is roll-coated with UV finish paint. The manufacturing method comprises the following steps of: manufacturing the stone
crystal base plate, manufacturing the stone crystal decorative plate, performing surface treatment of the stone crystal decorative plate,
cutting and slotting the stone crystal floor, packaging and warehousing. According to the mode, the composite floor made is prepared from the
polyvinyl chloride resin,
calcium carbonate and other main raw materials by
high polymer modifying and high temperature extruding, no glue and no
keel backing are needed in the
processing process, and the stone crystal floor is free of
aldehyde, environment-friendly, waterproof, fireproof, suitable for floor heating, and
pollution and acid and alkali-resistant, and has good
wear resistance.
