Abstract

The invention discloses a graphene-based additive for PVC floor and a preparation method thereof. The graphene-based additive is composed of the following ingredients (by weight): 100 parts of composite graphene, 1-30 parts of chlorinated polyethylene having the particle size of 400-800 microns, and 0.5-5 parts of a titanate coupling agent, wherein the composite graphene is formed by coating graphene having the particle size of 5-20 microns with titanium dioxide particles of 5-100 nm thick. The method comprises the following steps: firstly mixing graphene, titanium dioxide hydrosol and water and stirring to obtain graphene coated with titanium dioxide hydrosol; vacuum-drying to obtain composite graphene; placing the composite graphene into a dispersing and modifying all-in-one machine, adding chlorinated polyethylene and stirring, then adding the titanate coupling agent and stirring to prepare the target product. By adding the graphene-based additive as an additive into a PVC floor material, the electrostatic problem of the PVC floor is basically solved, thermal conductivity is improved by 30% and above, strength and toughness are obviously improved, and the product is also endowed with the antibacterial characteristic. Thereby, the target product is extremely easy to widely and commercially apply to PVC floor materials.

Description

technical field [0001] The invention relates to an additive and a preparation method, in particular to a graphene-based additive for PVC flooring and a preparation method thereof. Background technique [0002] At present, in the decoration and decoration project of the ground, there are various types of floors used, such as solid wood flooring, solid wood composite flooring, laminate flooring and PVC flooring. [0003] PVC flooring is made of polyvinyl chloride and its copolymer resin as the main raw material, adding fillers, plasticizers, stabilizers, colorants and other auxiliary materials, on the sheet continuous substrate, through coating process or calendering, extrusion or extruding It is a new type of light-weight floor decoration material that is very popular in the world today. Compared with other flooring materials, PVC flooring has obvious advantages such as light weight, environmental protection, non-slip, waterproof, various colors, and high cost performance, b...
