Abstract
The invention discloses high-concentration alcohol-based paint used in cast steel. The paint comprises 66-75% of refractory aggregates, 0.5-1.5% of a binder, 1.0-2.5% of a suspending agent, and 21-30% of isopropanol, wherein the refractory aggregates comprise 50-70% of white corundum, 20-40% of brown corundum, and 10-30% of mullite. The particle size distribution of the refractory aggregates is that: particles with diameters lower than 38mum accounts for 10-20%, particles with diameters of 38-53mum accounts for 40-60%, particles with diameters of 53-75mum accounts for 30-50%, and particles with diameters higher than 75mum accounts for 0-10%. According to the invention, the refractory aggregates with lower cost are intelligently selected for replacing a zircon powder aggregate, and characteristics of high refractory degree and surface fusion property are obtained as well. Also, the paint has large softening temperature zone. Through reasonable particle size selection and specific binder optimization, aggregate content is higher than 75%, such that excellent performance is obtained.
Description
Technical field
The present invention relates to a kind of foundry facing, relate in particular to a kind of casting alcohol radical alcohol-base paint.
Background technology
Patent retrieval in prior art is found, general take aluminous refractory as the cast paint of aggregate be all to select one or more different refractory materials is composite to form, and, for the distribution of particles of every kind of aggregate, often select a kind of granularity specification, and regulation is not very concrete.
And with the aggregate in alcohol-base paint, mostly select zirconium English powder at traditional high-quality cast steel, when acquisition was high-quality, a large amount of zirconium English powder also brought high material cost expenditure.
Summary of the invention
Technical problem to be solved by this invention is the high density high-quality casting alcohol-base paint that will provide a kind of price lower.
For solving the problems of the technologies described above, technical scheme of the present invention is as follows:
A kind of cast steel high density alcohol-base paint is characterized in that: comprise refractory aggregate 66～75%, binding agent 0.5～1.5%, suspending agent 1.0～2.5%, isopropyl alcohol 21～30%;
Wherein, described refractory aggregate comprises white fused alumina 50～70%, brown corundum 20-40% and mullite 10～30%; And the size distribution of described each refractory aggregate is by the 10-20% that accounts for below diameter 38 μ m, between diameter 38-53 μ m, account for 40-60%, between diameter 53-75 μ m, account for 30-50%, diameter 75 μ m are above accounts for 0-10%;
Described binding agent is comprised of newtrex and maleic rosin, and its weight ratio is 1:2;
Described suspending agent is organobentonite,
Above each ratio of component is classified percentage by weight as.
The refractory aggregate of high density alcohol-base paint of the present invention mainly is comprised of the corundum material of High-Alumina, and these materials are good from high, the sharp property of purity, acid-alkali-corrosive-resisting, high temperature resistant, hot performance are stable.White fused alumina is to take fine aluminum oxidation powder to be raw material, through electric smelting, refines crystallization and forms, and white fused alumina hardness is a little more than brown corundum, and toughness is slightly low.The palm fibre corundum is to take bauxite, anthracite, iron filings to be primary raw material, through pyrolytic semlting, forms in electric arc furnaces, is sepia, good toughness.During actual the use, utilize respectively the high refractoriness of white fused alumina and the toughness of brown corundum, make dope layer both guarantee refractoriness, bright and clean surface is arranged again.Mullite is as a kind of conditioning agent of refractoriness, and mullite is a series of mineral general designations that are comprised of aluminosilicate.The mineral that aluminosilicate at high temperature generates.Crystal is elongated needle-like and is radiation bunch shape.Mullite at high temperature can decomposite corundum and liquid phase, can adjust addition according to different foundry goods demand, guarantees that melt surface only occurs dope layer in the whole cast of foundry goods and process of setting.Like this, we just can replace zirconium English powder aggregate with the lower refractory aggregate of cost, utilize us through lot of experiments, summary, research, to obtain the mixing refractory aggregate of comprehensive proportioning and performance complement, obtain equally high refractoriness, possess the characteristic of melt surface, and have larger softening temperature interval.
For cast paint, the different grain size of aggregate distributes and directly reflects the difference of its specific area.Solvent in formulation for coating material, binding agent and suspending agent etc. are all to determine according to the character of aggregate, and the additional proportion of these additives has direct relation with the specific area of aggregate.If do not consider the size distribution of aggregate comprehensively, in traditional handicraft, the weight ratio of general refractory aggregate can only account for the 60%-70% of whole coating, the score that strengthens aggregate if continue will directly make coating property descend, the present invention, by rational granularity type selecting, specific binding agent optimization, makes aggregate content to reach more than 75%.
By the refinement size distribution with effectively guarantee the specific area of refractory aggregate, thereby guarantee the stability of coating quality.Stable aggregate specific area can be guaranteed the addition of binding agent in coating, guarantees coating surface strength in use.The granularity that refractory material is different, at high temperature can produce different melt temperatures, can utilize varigrained being uniformly distributed, make refractory material melt gradually in different temperature ranges, thereby can control the temperature range of dope layer softening and melting at high temperature.Make high density alcohol-base paint of the present invention obtain good combination property.
The accompanying drawing explanation
Fig. 1 shows the production technology of cast steel of the present invention with the high density alcohol-base paint.
