Abstract
The invention discloses a preparation method of resin coated color quartz sand. The key point of the technical scheme of the invention is as follows: the preparation method is implemented by taking quartz sand as a base material through the concrete preparation steps of the preparation of pigmental resin: mixing one or more base pigments, uniformly mixing the obtained mixture with resin in a proportion of 1:3-5, and grinding the obtained mixture into the pigmental resin for standby application; mixing and stirring the pigmental resin and the quartz sand, so that the pigmental resin is uniformly covered on the surface of the quartz sand, thereby obtaining a semi-finished product of colored sand; drying the semi-finished product of colored sand by using hot air at a temperature of 60-80 DEG C; putting the dried colored sand into a drying furnace to dry again for 0.5-1 hour at a temperature of 200-400 DEG C; and taking the re-dried colored sand from the drying furnace, putting the colored sand into a water-cooled roller to cool to 40-45 DEG C, taking out, cooling the obtained product to room temperature, and sieving the obtained product, so that a finished product is obtained. The color control difficulty of products set according to the preparation method of resin coated color quartz sand disclosed by the invention is greatly reduced, and the chromatic aberration is stable.
Description
Technical field
The present invention relates to a kind of manufacture craft of colorful quartz sands, in particular, it is colored that it is related to a kind of resin coating
The preparation method of quartz sand.
Background technology
Color sand, as the important aggregate of true mineral varnish, resin terrace, bituminized shingle, colored road surface etc., is widely used in building
Decoration industry.
Increasingly accepted by users with true mineral varnish, resin terrace, bituminized shingle, colored road surface etc., the consumption of color sand is just
Expand rapid.
Color sand is divided into natural colour sand and artificial color two kinds of sand.Natural colour sand because variegated many, color stability is poor, color is not united
The reason such as one and mineral resources anxiety, increasingly cannot meet use demand in the industry.Manually color sand is with its rich color, consistent
Property is strong, bright-colored etc., and factor is increasingly favored by user.
From preparation method, manually color sand is mainly made with three kinds of methods.
The first is organic pigment decoration method；
Second is binding agent solidification method, is coated on sand grains with the binding agent such as mixing such as resin, silicone inorganic color
Top layer, then baking-curing coloring at a temperature of 200-300 DEG C；
The third is high temperature glazing method, is to stick to sand grains top layer with inorganic pigment, then high temperature burns at 900-1200 DEG C
It is knotted color, inorganic pigment is mainly six kinds of basic pigments: iron oxide red, iron oxide yellow, iron oxide black, titanium white, cobalt green, cobalt blue.
In first method organic pigment not ageing-resistant also intolerant to rain-out, the stability of color is not high；Second side
In method, the quality of color sand is heavily dependent on the quality of bonding agent, but the glue bonding agent that the method is used is expensive,
Increased the preparation cost of color sand；Although the made color sand of the third method is fast in colour, particle is little, and its color is difficult to adjust
Join, energy consumption is big, complex procedures, be difficult to promote.And adopt resin coating coloured silk sand technique productions color sand stable performance out excellent,
But its color conditioning remains unchanged, relatively difficult and its color stability is difficult to control to.And the industry pair such as true mineral varnish, epoxide terrace
The color stability of color sand has high requirement.
Content of the invention
In view of the shortcomings of the prior art, it is an object of the invention to provide a kind of toning difficulty substantially reduces and color
The preparation method of stable resin coating colorful quartz sands.
For achieving the above object, the technical scheme is that a kind of preparation of resin coating colorful quartz sands
Method, with quartz sand as base-material, specific make step includes:
(1) making of pigmental resin: mix according to 1:3 ~ 5 ratio with resin again after one or more basic pigments are mixed
Uniformly grind to form pigmental resin standby；
(2) again pigmental resin and quartz sand are passed through mix and blend so that pigmental resin uniform fold is in quartz sand surface,
Obtain the color sand of semi-finished product；
(3) the color sand of semi-finished product is passed through 60 ~ 80 DEG C of hot-air seasonings；
(4) the color sand after drying is put in drying oven and carry out again after 0.5-1 hour at a temperature of 200-400 DEG C
Dry；
(5) after after taking out the color sand after drying again from drying oven, entrance water cold drum is cooled to 40-45 DEG C of taking-up
After being cooled to normal temperature again, screening gets product；
Wherein: described basic pigment includes: iron oxide red, iron oxide yellow, iron oxide black, titanium white, cobalt green, cobalt blue, described resin is acrylic acid
Resin；In described coloured silk sand, each component raw material weight proportioning of soup processed is:
100 parts of quartz sand
2 ~ 6 parts of pigmental resin.
As preferred, described quartz sand is sio298%, fineness is the silica sand of 40-80 mesh.
The present invention has an advantage that the present invention passes through the big basic pigment of selected six compared to existing technology, first prefabricated face
The method of material resin so that basic pigment and resin be fully compatible and color development is complete, fineness uniformly, so toning difficulty reduction,
Then it is critical only that the hot-air seasoning that the color sand of semi-finished product is first passed through 60 ~ 80 DEG C, after will drying through reheating
Color sand is put in drying oven and is dried 0.5-1 hour again in 200-400 DEG C, now through the pigment on the color sand surface of reheating
Resin is adhering completely on color sand, such coloured silk sand because 200-400 DEG C dry 0.5-1 hour during moisture by
Gradually reduce, the colour component of pigmental resin is deposited in color sand surface, and color fastness is high, and Color control is stable, enters back into water after taking-up
Chill roles are cooled to that the 40-45 DEG C of thermal adaptability naturally cooling to the color of color sand that normal temperature thus makes again is strong, and control color is difficult
Degree substantially reduces, and product aberration is stable；And the step making this resin coating colorful quartz sands is simple and clear, implement non-
Often facilitate, operation easier substantially reduces.
