Abstract

The invention provides a waterborne flame-retardant antirust paint and a preparation method thereof and belongs to the field of paint preparation technology. The paint is prepared from the following raw materials (by weight): 30-40 parts of acrylate modified alkyd resin, 20-25 parts of rosin phenolic resin, 5-8 parts of epoxy resin, 11-15 parts of a styrene-acrylic emulsion, 20-30 parts of water, 18-25 parts of a fire retardant, 0.2-0.4 part of anionic sodium alkyl succinate, 0.2-0.4 part of a silanol wetting agent, 1-3 parts of sodium bentonite, 1-1.5 parts of an antirust agent, 2-3 parts of a curing agent, 0.6-0.75 part of a pH regulator, 0.2-0.6 part of an antifoaming agent, 0.2-0.3 part of a leveling agent, and 3-4 parts of a cosolvent. The flame retardant is a magnesium-aluminum hydrotalcite hyper-branched fire retardant. The paint of the invention has good antirust and waterproof properties, and has strong adhesion and high hardness. After the magnesium-aluminum hydrotalcite hyper-branched fire retardant is added into the paint, fire resistance of the paint can be improved.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of paint preparation, in particular to a water-based flame-retardant antirust paint and a preparation method thereof. [0003] 【Background technique】 [0004] With the development of society and the enhancement of people's awareness of environmental protection, water-based paint is used by more and more people. Water-based paint is a paint that uses water as a diluent and does not contain organic solvents. It does not contain benzene, toluene, xylene, and formaldehyde. , free TDI toxic heavy metals, non-toxic, non-irritating odor, harmless to the human body, does not pollute the environment, the paint film is full, crystal clear, good flexibility and has water resistance, wear resistance, aging resistance, yellowing resistance, fast drying, easy to use Features. But existing water-based paints have poor fire-resistance and anti-rust properties and poor water resistance. Therefore, it is necessary to...
