Abstract
The present invention be adopt by natural rhombohedral iron ore stone through Mechanical Crushing and ore grinding make natural iron oxide red, replace the raw material of expensive red iron oxide as priming paint, opened up the purposes field of rhombohedral iron ore stone, this natural iron oxide red cheap and easy to get, replace red iron oxide to be up to state standards.
Description
The present invention utilizes natural rhombohedral iron ore production natural iron oxide red to replace the red iron oxide in the priming paint.
Natural rhombohedral iron ore stone conventional use is to be used for smelting iron and steel industry, mainly refines the raw material of the pig iron as blast furnace.
Red iron oxide is to produce the requisite raw material of priming paint, but its complex manufacturing, quality product is wayward, is difficult to realize producing in enormous quantities, and the nitric acid that the production red iron oxide is used, soda ash not only costs an arm and a leg, and is China's raw material in short supply; In the red iron oxide production process, also produce a certain amount of waste liquid, cause environmental pollution.The product cost of red iron oxide is higher.
It is natural iron oxide red to the objective of the invention is to utilize natural rhombohedral iron ore stone to produce, and opens up rhombohedral iron ore stone new application, with natural iron oxide red replacement red iron oxide cheap and easy to get.
The object of the present invention is achieved like this, and it is broken and time in grinding production is natural iron oxide red that natural rhombohedral iron ore stone is carried out conventional mechanical, in order to the red iron oxide in the replacement priming paint.
The present invention has widened the purposes scope of rhombohedral iron ore stone, rhombohedral iron ore stone is fully used, make it to be applied to smelting iron and steel industry, can also produce with the method for Mechanical Crushing and ore grinding and meet the natural iron oxide red of national standard, be applied to coating industry to replace red iron oxide.Natural rhombohedral iron ore raw material is cheap and sufficient, produces natural iron oxide red technology to be simple and easy to grasp, and quality product is very easily controlled.The natural iron oxide red product cost of producing only is 43% of red iron oxide.Chemical examination by analysis, natural iron oxide red every technical indicator to red iron oxide is similar substantially, meets red iron oxide GBH103 standard.
This natural iron oxide red being applied to proved through application test in the red iron oxide alkyd primer, natural iron oxide redly can replace red iron oxide fully, reached national standard.This priming paint opacifying power is good, no sag, and promptly levelling property is better, and colo(u)rant dispersion power is good, and solvability is good, and wherein performance such as hardness, wear-resisting, shading, salt water resistance also is better than red iron oxide.Owing to use the natural iron oxide red cost that also reduces priming paint.
The present invention is provided by following examples.
The mineral composition of natural rhombohedral iron ore and chemical ingredients be, ore grade reaches more than 53%, and ferric oxide and silicon-dioxide sum are greater than 96%, and iron protoxide, calcium oxide, magnesium oxide, sulphur equal size are no more than 0.2%.With thick broken the reaching under the granularity 150mm of ore, picking again reaches more than 53% grade, through thin broken reaching below the granularity 10mm, grinding again.Last selection by winnowing reaches and is natural iron oxide red product more than 320 orders.
Be applied in the red iron oxide alkyd primer natural iron oxide red, it is as follows to fill a prescription:
Synolac 440Kg, barium sulfate 110kg, natural iron oxide red 280kg, talcum powder 90kg, solvent 100kg, mixed dry material 14kg.
Claims (1)
- A kind of iron oxide red that is used for priming paint, it is characterized in that the present invention adopts be by natural rhombohedral iron ore stone through Mechanical Crushing and milling method make natural iron oxide red, to replace the red iron oxide in the former priming paint.
