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 relates to a kind of preparation method of resin coating colorful quartz sands.
Background technology
Color sand, as the important aggregate of true mineral varnish, resin terrace, bituminized shingle, colored road surface etc., is widely used in architectural decoration.
Along with true mineral varnish, resin terrace, bituminized shingle, colored road surface etc. are accepted by users day by day, the consumption of color sand expands rapidly.
Color sand is divided into natural colour sand and two kinds, artificial color sand.Natural colour sand, because of variegated many, the reason such as color stability is poor, color disunity and Mineral resources are nervous, more and more cannot meet user demand in the industry.Artificial color sand is with the favor of factor is more and more the subject to user such as its rich color, consistence be strong, bright-colored.
Preparation method, artificial color sand is mainly made by three kinds of methods.
The first is pigment dyestuff staining;
The second is adhesive cures method, and be coated on sand grains top layer with binding agent as resin, silicone based etc. mixes inorganic color, then at 200-300 DEG C of temperature, baking-curing is painted;
The third is high temperature glazing method, is to stick to sand grains top layer with mineral dye, then high temperature sintering is painted at 900-1200 DEG C, and mineral dye is mainly six kinds of basic pigments: iron oxide red, iron oxide yellow, iron oxide black, titanium white, cobalt green, cobalt blue.
The not ageing-resistant also not resistance to rain-out of pigment dyestuff in first method, the stability of color is not high; In second method, the quality of color sand depends on the quality of caking agent to a great extent, but the glue caking agent that the method uses is expensive, adds 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 allotment, and energy consumption is large, and complex procedures, not easily promotes.And adopt the color sand stable performance out of the color sand explained hereafter of resin coating excellent, but its color conditioning remains unchanged, stability that is more difficult and its color is difficult to control.And the color stabilities of industry to color sand such as true mineral varnish, epoxide terrace have high requirement.
Summary of the invention
For the deficiency that prior art exists, a kind of difficulty of mixing colours is the object of the present invention is to provide greatly to reduce and the preparation method of the resin coating colorful quartz sands of color stable.
For achieving the above object, the invention provides following technical scheme: a kind of preparation method of resin coating colorful quartz sands, take quartz sand as base-material, concrete making step comprises:
(1) making of pigmental resin: mix after being mixed by one or more basic pigments that to grind to form pigmental resin for subsequent use again with resin according to 1:3 ~ 5 ratio;
(2) again pigmental resin and quartz sand are passed through mix and blend, make pigmental resin uniform fold at quartz sand surface, obtain half-finished color sand;
(3) half-finished color sand is passed through 60 ~ 80 DEG C of hot-air seasonings;
(4) the color sand after drying is put into stoving oven at the temperature of 200-400 DEG C, to go through 0.5-1 hour again dry;
(5) enter after the color sand after again drying being taken out from stoving oven after being again cooled to normal temperature after water cold drum is cooled to 40-45 DEG C of taking-up and sieve and get product.
As preferably, described quartz sand is SiO
2≤ 98%, fineness is 40-80 object silica sand.
As preferably, described basic pigment comprises: iron oxide red, iron oxide yellow, iron oxide black, titanium white, cobalt green, cobalt blue, and described resin is acrylic resin.
As preferably, in described color sand, each component raw material weight proportion is:
Quartz sand 100 parts
Pigmental resin 2 ~ 6 parts.
The present invention has following advantage compared to existing technology: the present invention is by six selected large basic pigments, the first method of prefabricated pigmental resin, make basic pigment and resin completely compatible and color development is complete, fineness is even, such toning difficulty reduces, then key is half-finished color sand first through the hot-air seasoning of 60 ~ 80 DEG C, color sand after being about to oven dry through second-heating puts into stoving oven dries 0.5-1 hour again in 200-400 DEG C, pigmental resin now through the color sand surface of second-heating is attached on color sand completely, color sand like this reduces gradually because dry moisture content in the process of 0.5-1 hour at 200-400 DEG C, the colour component of pigmental resin is deposited in color sand surface, colour fastness is high, Color control is stablized, entering water cold drum after taking-up again, to be cooled to the 40-45 DEG C of thermal adaptability naturally cooling to the color of the color sand that normal temperature so just makes again strong, control look difficulty reduces greatly, product aberration is stablized, and the step making this resin coating colorful quartz sands is simple and clear, implement very convenient, operation easier reduces greatly.
