Environment-friendly water-based paint and preparation method thereof

Abstract

The invention provides an environment-friendly water-based paint and a preparation method thereof. The environment-friendly water-based paint comprises the following components in parts by weight: deionized water, a film formation accessory ingredient, a wetting agent, a dispersing agent, a nanometer material, a filling material, natural plant water-based resin, natural plant water-based color paste and a scratch resistance agent or a slipping agent. The preparation method comprises the following steps of: A, preparing a water-based dispersoid; B, adding the water-based dispersoid obtained in the step A into a stirred emulsion, then adding the film formation accessory ingredient and uniformly stirring and dispersing; C, adding pigment; and D, supplying water, and blending to obtain the water-based paint when the Stormer viscosity is 65 to 90 KU at the temperature of 25 DEG C. The environment-friendly water-based paint is wide in application range, has high covering power, high adhesive force and high water resisting property, chemical resistance and abrasion resistance and is safe and environment-friendly; a static electricity phenomenon is avoided; and the volatilization amount of organic compounds and the heavy metal content can be reduced.

Description

technical field [0001] The invention relates to a water-based paint and a preparation method thereof, in particular to an environment-friendly water-based paint and a preparation method thereof. Background technique [0002] Traditional solvent paint (commonly known as paint) will cause harm to human health and the environment, especially when used indoors, toxic organic solvents such as benzene continue to volatilize for a long time, directly endangering human health and life safety. For example, volatile organic compounds (VOCs) can cause headaches, nausea, sore throat, asthma and other symptoms; free isocyanates (TDI) are inhaled and accumulated toxic compounds that can cause bronchitis, asthma, and even suffocation; benzene is a high Toxic carcinogens mainly affect the hematopoietic system and nervous system; lead makes paints have various bright colors, but the harm of lead to the human body cannot be underestimated. For people who have been exposed to trace amounts of...
