Embodiment 1

[0018] Scratch-resistant super wear-resistant PVC transparent sheet, the scratch-resistant super wear-resistant PVC transparent sheet includes polyurethane coating 1, hollow glass bead layer 2 and PVC calendered lower layer 3, wherein the hollow glass bead layer contains organic coating layer 21, glass layer 22. The hollow layer 23. The surface hardness of the invention can reach pencil hardness 9H, and has excellent mechanical properties, wear resistance, scratch resistance, aging resistance, good toughness, light weight, long service life, energy saving, sanitation and environmental protection, waterproof, mold proof and antifouling. It can be widely used in the fields of PVC plastic floor and desktop soft glass.

Embodiment 2

[0020] The manufacturing method of the anti-scratch and ultra-wear-resistant PVC transparent sheet of Example 1 is as follows: add PVC resin, transparent calcium-zinc composite stabilizer, and environmentally friendly non-toxic plasticizer in proportion to a high-low speed mixing unit and stir at a high speed to 80-100 ° C, then mix at a low speed. After stirring and cooling to 40-50°C, add planetary screw extruder to extrude and plasticize at a temperature of 160°C-180°C. The PVC calendering lower layer 3 is formed after the five-roller calendering, and the hollow glass microspheres coated with the ion beam organic coating are sprayed at high pressure on the upper surface of the PVC calendering lower layer 3, and the hollow glass microbead layer 2 is formed after rolling and cooling. Polyurethane coating is sprayed on layer 2, light-cured to form polyurethane coating 1, and after cooling and winding, the anti-scratch and super wear-resistant PVC transparent sheet of the presen...

Abstract

The invention provides a scraping-resisting super wear-resisting PVC (polyvinyl chloride) transparent sheet and a manufacturing method thereof, belongs to the technical field of PVC sheets, and is characterized in that the scraping-resisting super wear-resisting PVC transparent sheet is of a three-layer composite structure comprising a polyurethane coating, a hollow glass bead layer and a PVC calendaring lower layer from top to bottom, wherein the hollow glass bead layer is of a hollow three-layer spherical composite structure comprising an organic coating layer, a glass layer and a hollow layer from outside to inside. The surface hardness can reach pencil hardness 9H, and the scraping-resisting super wear-resisting PVC transparent sheet has the advantages of excellent mechanical property, wear resistance, scraping resistance, aging resistance, good toughness, light weight, long service life, energy saving, sanitation and environmental protection, waterproofness, mildew resistance and antifouling property, and can be widely applied to the fields of PVC plastic floor and desktop soft glass.

Description

technical field [0001] The invention belongs to the technical field of PVC sheets, and mainly relates to a scratch-resistant super wear-resistant PVC transparent sheet and a manufacturing method thereof. Background technique [0002] PVC transparent sheet is mainly used in PVC plastic floor, soft door curtain, desktop soft glass and other fields. As a wear-resistant layer for plastic floors, it fully guarantees the excellent wear-resistant performance of the floor material. The wear-resistant layer on the surface can be used for 3-5 years under normal conditions depending on the thickness. The thickness of the wear-resistant layer directly determines the PVC The service time of the plastic floor, the standard test results show that the 0.55mm thick wear-resistant layer floor can be used for more than 5 years under normal conditions, and the 0.7-0.8mm plastic floor can be used for more than 8-10 years. [0003] However, the scratch resistance of the existing plastic floor we...
