Abstract
The invention discloses a preparation method of an iron oxide red for artificial marbles. According to the invention, after the iron oxide red is added into an artificial marble, the artificial marble is bright in color and high in hardness.
Description
Technical field
The present invention relates to the red iron oxide field, is exactly the preparation method of a kind of artificial marble by red iron oxide.
Background technology
Red iron oxide (Iron Oxide Red) claims again that iron oxygen is red, colcother, rust are red, has natural and artificial two kinds.Natural title is western red, is basically pure ferric oxide, is red powder.Due to the difference of production method and operational condition, their crystalline structure and physical behavior have very large difference, and color and luster changes in orange light to blue light between purple light.Opacifying power and tinting strength are all very large.Density 5-5.25.Superior fast light, resistance to elevated temperatures are arranged, and anti-atmospheric influence, resistant foul smell body, anti-all bases.Only in the situation that heat in concentrated acid just and can dissolve gradually.
Summary of the invention
The object of the present invention is to provide the preparation method of a kind of artificial marble by red iron oxide
Above-mentioned purpose realizes by following scheme:
The preparation method of red iron oxide for a kind of artificial marble is characterized in that:
(1), by the potassium felspar sand fragmentation, abrasive dust, after crossing the 60-100 mesh sieve, calcining 1-2 hour under 700-800 ℃, take out again, cooling, soak 5-10 hour in the sodium hydroxide solution that is 7-12% in concentration again, take out, deionized water wash, dry, add again the vanadium boride that is equivalent to its weight 1.6-2.2%, the Resorcinol of 0.1-0.2%, the butyl acrylate of 0.4-0.6%, after mixing, high speed shear 10-20 minute under 2000-3000rpm, obtain the modification feldspar in powder standby;
(2) take 0.1-0.4 part dipropylene glycol, 0.4-0.6 part Tripolyglycerol monostearates, 0.1-0.2 part Arlacel-80,1-2 part zinc naphthenate, after mixing, add appropriate amount of deionized water, after stirring after 40-50 ℃, obtains mixed solution standby;
(3) after iron oxide blue and mixed solution are mixed, under 2000-3000rpm after high speed shear 10-20 minute, then add the modification feldspar in powder, continue at high speed shear 10-20 minute under 2500-3600rpm, take out and dry, obtain.
The preparation method of red iron oxide for described a kind of artificial marble, it is characterized in that: the described bake out temperature of step (3) is 60-70 ℃.
Beneficial effect of the present invention is: the present invention is added in artificial marble, lovely luster, and hardness is high.
Embodiment
The preparation method of red iron oxide for a kind of artificial marble,
(1), by the potassium felspar sand fragmentation, abrasive dust, after crossing 100 mesh sieves, calcine 2 hours under 800 ℃ again, take out, cooling, in the sodium hydroxide solution that is 8% in concentration again, soak 7 hours, take out, deionized water wash, dry, add again the vanadium boride that is equivalent to its weight 1.9%, 0.2% Resorcinol, 0.5% butyl acrylate, after mixing, under 3000rpm, high speed shear is 20 minutes, obtains the modification feldspar in powder standby;
(2) take 0.3 part of dipropylene glycol, 0.6 part of Tripolyglycerol monostearates, 0.2 part of Arlacel-80,2 parts of zinc naphthenates, after mixing, add appropriate amount of deionized water, after stirring after 50 ℃, obtains mixed solution standby;
(3) after iron oxide blue and mixed solution are mixed, high speed shear after 20 minutes under 3000rpm, then add the modification feldspar in powder, continue under 2700rpm high speed shear 20 minutes, dries under taking out 60-70 ℃, obtains.
The red iron oxide product performance analytical data that embodiment produces is as following table:
| Project | Index | Detected result |
| The water solubles (%) | ≤1.0 | ?0.68 |
| 105 ℃ of volatile matters (%) | ≤1.0 | 0.72 |
| Oil number (%) | 15-25 | 22.9 |
| Tinctorial strength (%) | 95-105 | 98.2 |
| Anti-200 ℃/30min (△ E) | ≤1.0 | 0.78 |
