Problems solved by technology

Water-based alkyd resin has good salt spray resistance and good fullness of the coating film, but the hardness of the coating film is not good and the drying is slow, while the water-based acrylate emulsion is relatively fast drying, good water resistance and high hardness. The preparation of acrylic acid modified alkyd antirust paint can effectively improve the problems of single alkyd antirust paint such as high drying, slow drying and poor initial water resistance.

Embodiment Construction

[0031] In order to better understand the present invention, the technical solution of the present invention will be described in detail below with specific examples, but the present invention is not limited thereto.

[0032] The preparation method of the water-based acrylic acid modified alkyd antirust paint of following embodiment, comprises the following steps successively:

[0033] (1) Add the formulated amount of water-based alkyd resin, water-based drier and pH regulator at 600rpm and stir at a high speed until the mixture is evenly mixed, then slowly add deionized water, and continue to disperse for 10-15 minutes to obtain a varnish;

[0034] (2) Add defoamer, wetting and dispersing agent, titanium dioxide, carbon black, mica, zinc phosphate, aluminum tripolyphosphate, barium sulfate in sequence, disperse at 600rpm for 10-20min at a high speed until evenly mixed, and then use a sand mill to grind until Fineness≤20μm;

[0035] (3) Use a 100-mesh filter cloth to filter th...

Abstract

The invention discloses waterborne acrylic modified alkyd antirust paint and a preparation method thereof. The antirust paint is prepared from waterborne alkyd resin, epoxy modified acrylic emulsion,acrylate emulsion, waterborne drier, deionized water, a pH conditioning agent, a wetting dispersant, a defoaming agent, titanium dioxide, carbon black, mica, zinc phosphate, aluminum triphosphate, barium sulfate, an anti-settling agent, an antirust agent, a base material wetting agent and a thickening agent. The waterborne acrylic modified alkyd antirust paint has the advantages of application toconstruction in outdoor complex environment, quickness in drying, quickness in hardness increasing and good initial water resistance.

Description

technical field [0001] The invention relates to the field of design chemical coatings, in particular to a water-based acrylic modified alkyd antirust paint and a preparation method thereof which can be used for construction in complex outdoor environments. Background technique [0002] Because of its good protective performance and high cost performance, alkyd antirust paint is widely used in industrial coatings, including production equipment, ships, containers, bridges, gas tanks, port machinery, chemical equipment, railway tank cars, electrical machinery, storage tanks , pipeline inner wall, various steel structures, etc. Traditional alkyd antirust paints are mainly oil-based paints with high VOC (volatile organic compound) content, which brings harm to construction personnel and the environment. In recent years, with the gradual improvement of environmental protection regulations and the maturity of technology, environmentally friendly water-based coatings have become i...
