Abstract

The invention belongs to the field of chemical engineering paint and particularly relates to graphene formaldehyde-resisting paint and a preparing method thereof. The graphene formaldehyde-resisting paint is prepared from water, cellulose, a wetting agent, an anti-freezing agent, a thickening agent, a defoaming agent, titanium dioxide pulp, padding pulp, a multifunctional amine assistant, emulsion, a coalescing agent, a sterilizing agent, a flatting agent and a formaldehyde resisting agent, wherein the formaldehyde resisting agent is a mixture of graphene and nanometer titania. According to the graphene formaldehyde-resisting paint and the preparing method thereof, a traditional formulation is improved, graphene serves as a photocatalytic carrier by means of the light transmittance of graphene, and thus the efficiency of a photocatalytic reaction is greatly improved. Meanwhile, graphene is added to nanoscale titania, the absorption rate of visible light is increased, and the electron conduction efficiency is improved. In addition, due to the addition of graphene, the wear-resisting property of the water-based emulsion paint is improved.

Description

Technical field [0001] The invention belongs to the field of chemical coatings, and particularly relates to a graphene anti-formaldehyde coating and a preparation method thereof. Background technique [0002] Formaldehyde, also known as formic aldehyde, is the simplest aldehyde. It is usually a combustible, colorless and irritating gas. Formaldehyde is an important organic raw material, mainly used in the plastic industry, synthetic fibers, leather industry, medicine, dyes, etc. [0003] However, formaldehyde is also toxic. Long-term exposure to low-dose formaldehyde can cause chronic respiratory diseases, causing nasopharyngeal cancer, colon cancer, brain tumors, menstrual disorders, and gene mutations in the nucleus. Among all contacts, children and pregnant women are particularly sensitive to formaldehyde, and the harm is even greater. [0004] Due to the improvement of living standards, more and more people like to decorate their houses. However, when decorating houses, they co...
