Abstract

The invention discloses a high-thermal-stability SPC floor and a manufacturing method thereof. The high-thermal-stability SPC floor comprises a wear-resistant layer, a color film decoration layer and an SPC base material layer which are sequentially arranged from top to bottom. The SPC base material layer is prepared from the following components in parts by weight: 50 to 72 parts of polyvinyl chloride resin powder, 184 to 225 parts of modified heavy calcium carbonate, 10 to 18 parts of regenerated rubber, 15 to 20 parts of plasticizer, 1.2 to 3 parts of stabilizer and 1 to 3 parts of dispersing agent; the modified heavy calcium carbonate is obtained by using heavy calcium carbonate as a base material and modifying by using a copolymer. According to the high-thermal-stability SPC floor and the manufacturing method thereof, the regenerated rubber is added into the SPC base material layer, and the heavy calcium carbonate is modified, so that the finally obtained base material is good in integration, good in thermal stability and not prone to deformation, and the durable usability of the SPC floor can be greatly improved.

Description

technical field [0001] The invention relates to the field of SPC flooring, in particular to a high thermal stability SPC flooring and a manufacturing method thereof. Background technique [0002] The SPC floor is mainly a composite bottom plate formed by combining polyvinyl chloride resin, high-fill calcium powder and various additives. It is a new type of material invented in response to national emission reduction, hard SPC indoor flooring. The SPC floor uses calcium powder as the main raw material. After plasticizing and extruding the sheet, four-roll calendering heat-applied color film decorative layer and wear-resistant layer, it does not contain heavy metal formaldehyde and harmful substances. It is environmentally friendly, cheap, waterproof, moisture-proof, non-slip, Insect-proof, flame-retardant, no cracking, no deformation, no pollution, easy to clean, etc. [0003] At present, the SPC floor structure on the market is composed of wear-resistant layer, color film ...
