Abstract

The invention discloses a graphene-based / montmorillonite-modified polyurethane floor material and a preparation method thereof. The graphene-based / montmorillonite-modified polyurethane floor material is prepared from the following components in parts by weight: 27-47 parts of polyurethane, 7-14 parts of isocyanate, 3-6 parts of a defoaming agent, 1-4 parts of a wetting dispersant, 1-6 parts of a water absorbent, 1-4 parts of a catalyst, 6-18 parts of graphene, 8-17 parts of montmorillonite, 3-11 parts of ferric chloride, 3-12 parts of sodium carbonate, 3-17 parts of hydrochloric acid and 8-19 parts of borax. Compared with the prior art, the graphene-based / montmorillonite-modified polyurethane floor material disclosed by the invention has the advantages that no free isocyanate is produced in the product, no organic volatile substances are introduced, and the mechanical and chemical properties are good.

Description

technical field [0001] The invention belongs to the field of material chemistry and relates to a flooring material, in particular to a graphene / montmorillonite-based polyurethane flooring material and a preparation method thereof. Background technique [0002] At present, the widely used ground materials mainly include the following types: epoxy resin floor materials, cement floors, ceramic floor tiles, plastic floors, floors, etc. These materials have their own characteristics and advantages, but also have obvious disadvantages. Epoxy floor materials have high hardness, high compressive strength, and good wear resistance, but are brittle and easy to crack; cement floors have high mechanical strength and low price, but are easy to seep water and oil, are difficult to clean, and have poor corrosion resistance; Floor tiles have high hardness and good decoration, but they have poor load-bearing capacity, are not resistant to impact and rolling, and are easy to accumulate dust ...
