Embodiment Construction

[0029] The principles and features of the present invention are described below, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0030] The specific implementation steps are as follows:

[0031] 1) drop into water-based acrylic acid modified polyester resin, water-based acrylic acid fatty acid modified epoxy resin, water-based acrylic acid modified alkyd resin;

[0032] 2) Rotate at 300-1200r / min, put in pH neutralizer and deionized water;

[0033] 3) The rotation speed is 300-1200r / min, and the dispersing wetting agent and defoamer are put into it;

[0034] 4) The speed is 300-1200r / min, and the pigments and fillers are put in one by one;

[0035] 5) 300-1200r / min, disperse for 10-15 minutes;

[0036] 6) Grinding the slurry, using a horizontal sand mill to grind 2-4 times, subject to a fineness of 30 μm, and controlling the temperature of the slurry below 60°C;

[0037] 7) The rotat...

Abstract

The invention relates to a water-based paint used for metal drilling head surface protection, and a preparation method thereof. The water-based paint used for metal drilling head surface protection comprises, by weight, 0 to 40 parts of water-based acrylic acid saturated polyester resin, 0 to 70 parts of water-based acrylic acid aliphatic acid modified epoxy resin, 0 to 30 parts of water-based acrylic acid modified alkyd resin, 3 to 20 parts of an amino resin, 0.1 to 2 parts of a pH neutralizer, 0 to 2 parts of an acidic catalyst, 20 to 60 parts of deionized water, 0.1 to 2 parts of a wettingdispersing agent,, 0.01 to 0.2 part of an anti-foaming agent, 0 to 2 parts of a clunging promoter, 0 to 30 parts of a pigment filling material, 0.1 to 1 part of a leveling wetting agent, and 0.2 to 2parts of a water-based rheological auxiliary agent. The water-based paint used for metal drilling head surface protection possesses excellent stability, high solid content, low viscosity, and low VOCcontent, excellent protection performance, anti-rusting performance, and corrosion resistance on steel materials, and ideal hardness, impact resistance, toughness, and clunging force.

Description

technical field [0001] The invention relates to a water-based coating used for metal drill surface protection and a preparation method thereof, belonging to the field of water-based coatings. Background technique [0002] At present, solvent-based coatings are mainly used in the market, that is, paints to protect the surface of metal drill bits in electric tools. The carrier of this type of product is a volatile organic solvent, which will volatilize into the atmosphere during the film forming process and cause pollution to the environment and human health. harm. [0003] As the film-forming substance of water-based paint, water-based resin, the solid content, viscosity and VOC content of its aqueous dispersion play a decisive role in the performance of the paint film and the impact on the environment. Therefore, water-based paint is more and more popular as a low-VOC content paint. Applications. However, due to the low solid content of water-based paints, it is difficult ...
