Abstract

The invention provides an antirust paint of calcium fluophosphate alkyd. The composition has the following weight percentages: 38 weight percent to 58 weight percent of alkyd resin, 35 weight percent to 55 weight percent of rust-proof powder of calcium fluophosphate, 1 weight percent to 3 weight percent of dispersing agent, 1 weight percent to 10 weight percent of anti-settling agent, 1 weight percent to 2 weight percent of dried material and 1 weight percent to 8 weight percent of mixed solvent. The invention has the following advantages: the antirust powder of white composite silicon and titanium of excellent performance and reasonable price is used for replacing lead red and has no poisonous damage to people and the biological environment; other colors, fillers and auxiliary agents are skillfully used for getting the unique white color. At the same time, the paint has strong steel compatibility and strong corrosion-delaying performance of anode; the salt-resistant dipping time can reach above 600 hours (the national standard salt-resistant dipping time of alkyd and epoxy lead red is 24 hours to 96 hours); the neutrality-resistant and salt fog resistant time is more than 200 hours; the coating quantity in unit area is only 30 percent to 40 percent of the lead red.

Description

technical field [0001] The invention relates to the technical field of paint making, in particular to a calcium fluorophosphate alkyd antirust paint. Background technique [0002] Industry competition is becoming increasingly fierce, products are constantly updated, and environmental awareness is constantly improving. Although traditional products have their advantages, they need to gain their own benefits at the cost of damaging the environment. Such as Hongdan antirust paint, although the effect of antirust quality is relatively good in the current antirust paint, but due to the high lead content, it is easy to produce poisonous fog during construction and eradication of old Hongdan paint and welding, which is harmful to construction. Human injury is extremely serious and difficult to heal. The shoveled red lead paint or the red lead paint sprayed on the ground will seep into the ground or flow into the river to pollute the water quality, which is not good for human heal...
