A kind of ultra-wide environmental protection decorative film material and preparation process thereof

Abstract

The invention relates to a super-wide environmental-friendly decorative film material and a preparation technology thereof. The super-wide environmental-friendly decorative film material is prepared from high degree-of-polymerization PVC (Polyvinyl Chloride) resin powder, a environmental-friendly plasticizer, a stabilizer, a fire retardant, an internal lubricant and a mildew preventive serving as main raw materials by adopting working procedures such as material sieving, material blending, high-speed mixing, smelting, crude refining, refining, extrusion and filtrating, rolling, embossing, cooling and shaping, trimming, reeling and the like. The super-wide environmental-friendly decorative film material solves the problem that a general plastic decorative film has strong peculiar smell when coming into use, does not contain harmful substances such as phthalate, lead and cadmium, and is environmental-friendly, suitable for use in rooms and harmless to human bodies.
