The present invention has simple technological process, abundant material, high efficiency and other advantages, and the color decorating quartzite product has bright and fast color.
Description
Technical field the present invention relates to a kind of finishing material development field, especially a kind of manufacture method of polychromy quartz sand.
The standard of living that the appearance of technical background buildings is decorated beautifying city, the economic strength that embodies each area and even whole country and people plays crucial effect.Reach the important subject that certain color effect is a building research always by various materials.And traditional building and ornament materials are crossed reasons such as difference because of weather resistance, impermeability and decorative effect, are progressively eliminated and replace.Therefore development of new building and ornament materials energetically in recent years.
Colorful quartz sands is the decoration aggregate that grows up in the world over past ten years, with natural color stone sand facies ratio, has bright in lusterly, and easy-weathering not, particle diameter and color such as can select arbitrarily at advantage, can be used as the painted aggregate and the powder drawing pigment of sand wall coating.
In Japan, Japanese kokai publication sho 53-8628 " sand is painted and used coloring powder " is to add starch, casein in the mineral dusts such as marble and silica flour.CMC, synthetic resin emulsions such as water-soluble fluidity macromolecular solution of natural synthetic such as PVA or vinyl acetate are tamanori, with mineral dye or pigment dyestuff aqueous dispersions combination dryings such as nonionic or teepol and phthalein, colcother, iron aniline yellows, make colored sand.
The manufacture method of the colored sand of the clear 59-24109 of Japan's special permission is: black basalt and phosphoric acid series tamanori are mixed, then mineral dye is mixed the colored sand that is stirred in 400 ℃ of left and right sides sintering and gets with it.
The colored sand of China's development claims color-enamel sand again.It mainly adopts the upper color technology of pottery oil, take quartz sand as raw material, adds color painting and water mixing on an amount of oil, forms at 1200 ℃ of-1350 ℃ of high temperature range sintering then.Afterwards, on the basis of this high temperature sintering, added trace quantity mineral agent (being solvent), reduced firing temperature, at 700 ℃ of-950 ℃ of left and right sides sintering and prestige.
In recent years, along with the use of soap-free emulsion, novel covering material and the improvement of other technology, the whiting of natural real stone paint, anti-stain characteristic and weathering resistance have obtained large increase.But natural real stone paint is owing to be subjected to the restriction of natural colour, and color change is not enough abundant, is difficult to satisfy customer requirements, has limited to a certain extent the use of true mineral varnish and has promoted.
China has abundant quartz sand resources, and colorful quartz sands has comparatively vast market in finishing material market.But, the most of producer that produces colorful quartz sands of China mainly concentrates in the Japan and Korea S enterprise, though China also has many families to make the producer of colorful quartz sands, but because of technology backward than Japan and Korea S enterprise, income and bad is sold Japan and Korea S enterprise so some city just is common quartz sand with starting material with lower price in finishing material market, sells us with higher price again after finished product is made by Japan and Korea S enterprise, therefrom seek exorbitant profit, cause the serious waste of China's fund.Therefore, the objective of the invention is to be used to solve above-mentioned practical problems in a kind of simple method for preparing colorful quartz sands of research.
Summary of the invention the purpose of this invention is to provide a kind of manufacture method of polychromy quartz sand, is used to solve problems such as existing development colorful quartz sands method complexity, technology are loaded down with trivial details.
For achieving the above object, the manufacture method of a kind of polychromy quartz sand of the present invention, comprise select materials, mix, stirring, the step such as painted, quartz sand and aluminum phosphate (P

Wherein, phosphorus pentoxide very easily absorbs moisture, and with the water intense reaction, every mole of phosphorus pentoxide is emitted 68 kilocalories of heats; And by adding the different pentavalent phosphorus oxyacid of how much generating of Heshui, such as metaphosphoric acid, pyrophosphoric acid, orthophosphoric acid etc., so claim again phosphoric anhydride.Emit a large amount of heats by means of Vanadium Pentoxide in FLAKES and water reaction just, silicon dioxide structure in the quartz sand is changed, atoms metal in the mineral dye is embedded in the lattice of silicon-dioxide, and then produces new crystalline network and make it colour-fast with stable inorganic pigment.
From the space structure of silicon-dioxide as can be seen, the valence orbit of silicon-dioxide is sp
2, and on oxygen, having lone-pair electron to exist, these lone-pair electron can combine with the unoccupied orbital of atoms metal in the mineral dye structure.Therefore when the preparation colour building decoration material, the selection inorganic pigment is colouring agent.
In addition, the aluminum phosphate (AlPO that is generated by phosphorus pentoxide and alundum (Al2O3)
4) itself metal ion is had suction-operated, make like this pigment again further firmly on quartz sand.
Advantage of the present invention is: technology is simple, raw material is sufficient, finished product is difficult for fading, bright in color, durable in use, can effectively save working routine, increases work efficiency, and also has skidproof effect, and has good market outlook.
The manufacture method of a kind of polychromy quartz sand of specific embodiment the present invention, comprise select materials, mix, stirring, the step such as painted, quartz sand and aluminum phosphate (P
