Abstract

The invention provides solvent-free polyurethane self-leveling terrace material, which comprises A, B and C components. A consists of 20 to 60 percent of vibrin, 0.1 to 1 percent of defoamer, 1 to 5 percent of color paste, 5 to 20 percent of powdered zeolite, and10 to 40 percent of kaolin or silica flour. B is liquid MDI with NCO equivalent of 127. The solvent-free polyurethane self-levelling terrace material has the advantages that dehydrated castor oil is used to prepare vibrin instead of polyether and polyester polyol; castor oil belongs to vegetable oil with wide sources, and is renewable; vegetable oil is low in cost as raw material for preparing coating, and is innoxious, friendly to the environment with high hardness.

Description

technical field [0001] The invention relates to a floor material, in particular to a solvent-free polyurethane self-leveling floor material and a preparation method thereof. Background technique [0002] Industrial flooring is a comprehensive subject covering building materials, chemicals and basic applications. The flooring industry has a history of 60 to 70 years, and its product technology and engineering technology are quite mature. The types of materials include: epoxy resin, as the earliest resin material used in flooring, its technology is the most mature and has the largest proportion. It is mainly solvent-free system, a small amount of water-based system, and very few solvent-based system materials. ; Acrylic (cross-linking) materials are unsaturated systems polymerized from methacrylic monomers. This type of material has excellent weather resistance and can be used in outdoor environments. At the same time, due to the rapid cross-linking reaction, the construction ...
