Abstract
The present invention is granular iron oxide red pigment of grain size of 5-100 mesh and its preparation process. The preparation process includes the following steps: compounding water solution of additive in the concentration of 0.3-10 % and heating to 30-100 deg.c; spraying the water solution to iron oxide red in a pelletizing machine to form the granular pigment gradually with the weight ratio of iron oxide red to the water solution being 100 to 15-40; and vibration sieving and stoving to obtain the product. The additive is the combination of two or more of CMCNa, PVA, sodium silicate, glutin, sodium lignosulfonate and ferrous sulfate. The granular iron oxide red pigment has the same performance and use effect as the powdered iron oxide red pigment and is favorable to prevent dust pollution, and may be used to replace powdered iron oxide red pigment.
Description
Technical field
The present invention relates to a kind of pigment and manufacture method thereof, particularly a kind of particulate iron oxide red and manufacture method thereof.
Technical background
Ferric oxide red colorant is powdery at present, because dust granules is little, often the crowd of contact very easily suffers from occupational illness, especially pneumoconiosis.Pneumoconiosis means that in activity in production the lung tissue fiber that sucks dust and take place turns to main disease, and it has sickness rate height, characteristics that mortality ratio is high.China is the maximum country of pneumoconiosis number of the infected in the world.Ministry of Health's statistical information in 2002 shows that the sick kind number of this typical occupational illness of pneumoconiosis has reached 430,000 people in China, is equivalent to the summation of other countries' number of the infected.Because various places dust work workman's examination rate is low to moderate below 30%, have in addition examination rate have only tens percent, therefore, the reported cases number is far below actual incidence.What dust hazard was the most serious is to cause the lung tissue fibrosis, often contacts industrial dust, also will cause the illness of skin, ear and eye.The prolonged and repeated effect of metal and abrasive dust can cause corneal injury, causes the cornea sensory deprivation and the corneal opacity.
Press the size and the optical characteristics of powder dust particle, it can be divided into visible dust, microscope dust and ultramicroscope dust.As seen dust is meant that particle diameter is greater than 10 μ m, macroscopic dust.The microscope dust is meant that particle diameter is 10-0.25 μ m, with the microscopic dust of optics.The ultramicroscope dust is meant that particle diameter is less than 0.25 μ m visible powder dust under Electronic Speculum.Particle diameter is the acceleration sedimentation, indiffusion greater than the particle of 10 μ m in still air; Particle diameter meets stokes (STOKES) rule at the dust of 10-0.25 μ m in still air, be the constant speed landing, is difficult for diffusion; Particle diameter lands very easy diffusion hardly less than the dust of 0.25 μ m in still air.The dust about 2 μ m is found in experimentation on animals, and is bigger to human body harm.
Pigment powder adds the shortcoming that the material metering is difficult in addition except dust pollution is serious, be difficult to be applicable on the automatic industrial manufacturing line and use.In the application of this external Powdered ferric oxide red colorant, drop into difficult dispersion the in water and other solvent, in materials such as coating, cement, pitch, easy caking, behind the plastic granulating, color easily changes, particle is frangible.
Summary of the invention
The objective of the invention is to provide a kind of and reduce environmental pollution, add material metering easily, be fit to the particulate iron oxide red and the manufacture method thereof of suitability for industrialized production for the deficiency that solves above-mentioned technology.
In order to achieve the above object, particulate iron oxide red of the present invention, be outside red iron oxide, to be provided with coating layer to constitute particulate state, particle diameter is at 3.96 millimeters to 0.15 millimeter, and the composition of described coating layer additive is the combination of two or more component arbitrarily in Xylo-Mucine, polyvinyl alcohol, water glass, gelatin, sodium lignosulfonate, the ferrous sulfate.The optimum range of particle diameter is at 1.65 millimeters to 0.35 millimeter.
Particulate iron oxide red manufacture method of the present invention may further comprise the steps: A, selected additive is made into the aqueous solution of 0.3-10%, is heated to 30-100 ℃; B, get Powdered red iron oxide, add in the tablets press, spray on the powder with the additive aqueous solution for preparing, form particle gradually, preferably the particle of regular shape for example can be the globular particle, also can be columniform particle; C, again by vibratory screening apparatus screening, the particulate iron oxide that obtains required particle diameter is red, material is dried to get product at last.Tablets press among the step B also can be selected disk balling machine for use, and what obtain is coccoid particle.
In granulation process, the proportion optimization of the Powdered red iron oxide and the additive aqueous solution is the additive aqueous solution of 0.3-10% with 15-40kg concentration in the Powdered red iron oxide of 100kg.Selected additive can be following chemical substance: optional two or more component makes up in Xylo-Mucine, polyvinyl alcohol, water glass, gelatin, sodium lignosulfonate, the ferrous sulfate.Proportioning between the various components can be any proportioning.Can select liquid spraying can for use during spray, applying pressure 0-0.5Mpa uses pressurized with compressed air.Vibratory screening apparatus can select for use the aperture at 1.65 millimeters to 0.35 millimeter.
Particulate iron oxide red manufacture method of the present invention is compared with common agglomeration technique, though common agglomeration technique can obtain granular iron oxide red pigment, but change the performance of product easily, influence result of use simultaneously, particularly drop into difficult dispersion the in water or other solution, the solvent.Resulting granules shape ferric oxide red colorant of the present invention, during use, under the prerequisite that has guaranteed the original performance of product, there is good particle to dissolve performance and dispersing of pigments, also improved simultaneously the tint retention energy of application product, particularly solved when pigment is used a difficult problem that is difficult for dispersion, easily lumps in materials such as coating, cement, pitch.Relatively aberration is very little for product form and aspect and standard, Da＜+0.7, Db＜+0.7, DL-0.4--0.7, tinctorial yield 98 one 102%.Percentage of damage in transportation＜5%, even and pulverize and also to be difficult for airborne dust, solved ferric oxide red colorant problem of environment pollution caused in use again.Good product mobility has solved a difficult problem that is difficult to automatic gauge in the modern industry production, and it is accurate, convenient to feed intake.
Resulting granules shape ferric oxide red colorant of the present invention, owing to select the additive and the processing condition of particular combinations, particle diameter is more than 0.147 millimeter, particle diameter is bigger, is the acceleration sedimentation in still air, indiffusion, can reduce dust pollution effectively, not have dust basically.Because resulting granules shape ferric oxide red colorant of the present invention is in the performance that does not change product, do not influence simultaneously on the basis of result of use and stopped dust, this has just solved the substitution problem of Powdered iron oxide red pigment, thereby has checked the spreading trend of occupational illness in the exposed population group.It has very major and immediate significance to the occupational illness problem that solution pigment dust pollution causes.
