Embodiment Construction

[0028] The used raw material kind of example 1,2,3 and proportioning ratio are as shown in table 3

[0029] Table 3 Coating Preparation (Total 500g)

[0030]

[0031] Note: dispersant 737 is COATEX PE737; defoamer 318 is SN-Defoamer318; defoamer 154 is SN-Defoamer154.

[0032] This example adopts the SDF-400 disperser with a blade diameter of 60mm. First, put the pigment and filler, half of the dispersant, and water into the material tank, and disperse for 30 minutes at 2000-2500r / min. At the same time, add AMP-95 to stabilize the pH value, and prepare a uniformly dispersed color paste. After the dispersion, adjust the speed of the disperser to 500r / min, slowly add the silica sol, and disperse at a low speed for 30 minutes. Afterwards, slowly add the uniformly mixed bisfluororesin and alcohol ester-12 into the dispersion tank, and at the same time add the remaining dispersant 737, defoamer, and emulsifier OP-10, and disperse for 100 minutes.

[0033]Thus, the dope was pr...

Abstract

The invention discloses a hydraulic inorganic non-bulking fireproof paint, which consists of beaded paint and hardener, wherein the beaded paint contains 15.0-35.0% silicasol, 5.0-20.0% bifluororesin, 0.2-1.0% condensed alcohol ester 12, 7.0-14.0% silicon micronized quartz powder, 8.0-15.0% nanometer titanium dioxide, 12.0-20.0% caoline, 0.1-1.0% adjuvant AMP-95, 0.2-1.5% disperser 737, 0.5-4.0% defoamer and emulsion through dispersing; the hardener is AQ210 (the content is 4-9% bifluororesin); the hardener and beaded paint are blended evenly in the electrostatic spraying equipment, which sprays wagon surface through sand.

Description

technical field [0001] The invention belongs to the field of paint compositions based on inorganic substances, especially the paint composition of alkali metal silicate with organic additives; meanwhile, it also belongs to the category of fireproof and antifouling paints. In addition, the invention relates to the technical field of coatings for electrostatic spraying. Background technique [0002] At present, domestic research on coatings is mainly focused on organic intumescent fire retardant coatings. For water-based inorganic non-intumescent fire retardant coatings, there are few domestic researches, and the literature report rate is almost zero. However, most of the decorative coatings used in rail cars are solvent-based, and the common problems are that they are not fireproof, easy to age, and have poor self-cleaning properties. Since the paint itself contains a lot of organic matter, when the temperature is high, it will burn and produce a lot of smoke and toxic gases...
