Abstract

The invention discloses a water-based environment-friendly modified kieselguhr oil paint and a preparation method thereof. The oil paint comprises the following raw materials in parts by weight: acrylate emulsion, waterborne polyurethane synthetic resin, dipropylene glycol butyl ether, deionized water, fatty acid polyglycol ester, a thickening agent, a de-foaming agent, dioctyl sodium sulfosuccinate, zinc oxide, a flatting agent, titanium dioxide pulp, modified kieselguhr and a water-based silane coupling agent. The inorganic flocculant is adopted for modifying the kieselguhr, so that the cohesion and anchoring strength of the water-based environment-friendly modified kieselguhr oil paint compounded according to the invention are enhanced. The absorbed harmful aromatic hydrocarbon substances are not released even if the external environment is changed, so that the permanent absorption effect can be achieved.

Description

technical field [0001] The invention mainly relates to an environmental protection paint and a preparation method thereof, in particular to a modified diatomite water-based environmental protection paint and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, more and more people pay attention to the quality of house decoration. As a functional and environmentally friendly water-based paint, oil-based paint has the advantages of obvious decorative effect, colorful paint film, and easy cleaning. It is widely used in furniture, fabric furniture, kitchen furniture, etc. However, oil-based paint has become the "number one killer" that endangers human life and health. Oil-based paint contains a large amount of toxic and harmful substances such as benzene, toluene, xylene, formaldehyde, free TDI, heavy metals, etc., and is accompanied by an unpleasant irritating smell. After these toxic gases volatilize, they are extremel...
