Title:
SELF-CLEANING IMPERMEABLE WATERPROOF SHEET, PREPARATION METHOD THEREFOR, AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/087803
Kind Code:
A1
Abstract:
The present invention relates to a self-cleaning impermeable waterproof sheet, a preparation method therefor and an application thereof. The waterproof sheet is prepared by mixing and extruding all raw materials of the sheet. The raw materials of the sheet comprise a polypropylene resin and a polymer elastomer, a cyclo-olefin copolymer and a polymer antistatic agent, wherein the cyclo-olefin copolymer and the polymer antistatic agent account for 5% to 30% of the total mass of the raw materials of the sheet, and the mass ratio between the cyclo-olefin copolymer and the polymer antistatic agent is 0.1 to 10:1. According to the present invention, the polymer antistatic agent and the cyclo-olefin copolymer are added to the sheet that uses the polypropylene resin and the polymer elastomer as main raw materials, such that the surface resistance is reduced, the surface of the sheet achieves long-acting stain-resistant and self-cleaning effects, the waterproofness and impermeability of the material can be effectively improved, and good mechanical properties of the material can be maintained. Meanwhile, the polymer antistatic agent and the cyclo-olefin copolymer can also achieve a synergistic effect, such that the surface of the sheet is more rigid, and the self-cleaning effect of the surface is improved.
