Description

Antiseized sand coating of high osmosis of casting usefulness and preparation method thereof
Technical field
The present invention relates to a kind of coating and preparation method thereof, particularly a kind of antiseized sand coating of high osmosis of casting usefulness and preparation method thereof.
Background technology
Cast paint is of a great variety, can be divided into two classes substantially: water based paint and organic solvent coating.Wherein organic solvent coating is applying after light promptly curable, be used with various self-hardening sand technologies, can not need dry, production cycle can be shortened, simplify technology, energy savings reduces the drying plant investment, be to be cast a kind of quick drying paint that the boundary widely uses, be widely used in the production of steel, iron, coloured foundry goods.But large-scale, particularly make slow progress in the production application of heavy section steel castings, this is that casting solidification is slow because of heavy section steel castings pouring temperature height, and temperature retention time is long; And OOS coating permeability is relatively poor, and coating high-temp intensity, the hot cracking resistance that exposes to the sun are low, and gas forming amount is bigger, can't satisfy the abominable working condition of heavy section steel castings, so that foundry goods is prone to defectives such as large tracts of land scab, burning into sand, pore.
Chinese patent application (application number is 03128100.1) discloses a kind of alcohol radical and water base serial chromite sand powder penetration-prevention cast paint, it is characterized in that preparing the sand mold cast paint with chromite sand, its composition quality percentage is: granularity is coarser than 280 order chromite sands 10~100%, all kinds of auxiliary refractory powders of 280~325 orders can be 0~90% respectively, binding agent 1.0~3.0%, suspending agent 1.5~6.0%, thickener 0.15~0.5%, carrier can be water or ethanol, methyl alcohol or isopropyl alcohol etc.Facts have proved that coating that this patent application obtains is lower and elevated temperature strength coating is not enough to the penetration of sand mold, coating precipitates caking easily, and is not easy to store, more can't infiltrate casting mold, core space, prevents foundry goods scab; The less stable of coating under heavy section steel castings long term high temperature environment, coating is easy to crack, come off, and molten steel is broken through coating easily and is infiltered sand mold.
Chinese patent application (application number is 200910046096.4) discloses a kind of Zircon powder alcohol group dope that is used for heavy castings, and refractory aggregate adopts and contains ZrO 265% above zirconium English powder, paint adhesion agent adopt vinsol resin and novolac resin to match, and its part by weight that accounts for coating is respectively: vinsol resin 0.3~0.6%, novolac resin 0.5~0.8%; Though present patent application can form fine and close film with the influence of the moisture in the obstruct molding sand to dope layer on the sand mold surface, can make again bonding system on certain high-temperature gradient, keep its performance effectively and stable performance, resist the washing away of continuous high temperature of molten steel, thereby guarantee the cast(ing) surface certain quality; But as easy scaling loss under the vinsol of binding agent and the thermoplastic phenolic resins high temperature, the high temperature coating intensity difference, foundry goods is easy to generate burning into sand; The coating that obtains of this patent application does not add other auxiliary osmotic agent in addition, so its penetration is undesirable, can not fill up gap between sand grains and sand grains effectively, prevents penetration; Carrier all adopts isopropyl alcohol in addition, and cost is too high.
Summary of the invention
The objective of the invention is to overcome the above-mentioned deficiency of prior art and a kind of antiseized sand coating of high osmosis of casting usefulness is provided, its permeability is strong, and gas forming amount is little, and humidity resistance is good, and have good elevated temperature strength and stability, can prevent from effectively that molten steel from directly contacting with sand mold to cause the scab defective.
