Abstract
The invention relates to a cenosphere filling metal coating and the manufacturing method thereof, comprising the procedures as follow: taking cenospheres with a diameter between 0.01 um and 20 um as filling material; treating the surface of these cenospheres; filling the base with these surface treated pcenospheres into the base proportionally and sufficiently mixing the base and the surface treated pcenospheres to achieve the finish product of cenosphere filling coating. The coating has great adhesive power, and well high temperature resistance and heat insulating performance and corrosion resistance, and reduces the cost of the production.
Description
Technical field
The present invention relates to a kind of foundry facing and manufacturing process thereof, particularly a kind of hollow micro-bead added metal type coating material and manufacture method thereof.
Background technology
Metal mold belongs to the Special Processes of Metal Castings technology in the casting field, is widely used in the production of casting aluminum alloy parts.This technological requirement has coating to be separated by between metal mold type wall and cast(ing) surface, to play the protective money genotype, regulate casting solidification speed, to be convenient to effect such as the foundry goods demoulding.Commercial coating series, the Dycote coating series developed of Foseco company for example be widely used in during the permanent mold casting of aluminum casting and low pressure casting produce in states such as English, U.S., methods already, but its prescription is not seen open report.In China, also developed the coating series of some function admirables, applied for several patents in this respect as the Central China University of Science and Technology.General its heat-insulating property of common chill coating is bad, and in order to improve its heat-insulating property, regular meeting adds a certain proportion of inserts in the base-material of coating, is to adopt insulation materials such as flake asbestos, diatomite at present mostly.But these existing insulation material effects and not obvious in actual applications.
Summary of the invention
The purpose of this invention is to provide a kind of hollow micro-bead added metal type coating material and manufacturing process thereof, adopt the chill coating of this explained hereafter promptly to have good suspension, screening characteristics, durability, have good heat-insulating property again.
The present invention is achieved like this, and at first gets cenosphere and sieves, and selects the cenosphere of granularity between 0.01～20 micron; Adopt the microwave ablution that cenosphere is carried out surface treatment then, after the processing cenosphere raw material is put into roaster and carried out roasting 1～2 hour; At last the cenosphere after the surface treatment is filled in the base-material of chill coating by predetermined ratio, fully mixes, obtain the finished product hollow microbead filling paint.
The composition of the resulting finished product hollow micro-bead added metal type coating material of the present invention comprises base-material and cenosphere, the ratio of wherein said cenosphere is between 5～40%, granularity is between 0.01～20 micron, and finished product coating can be powdery paints, solvent based coating or water paint.
The resulting metal type heat-insulation coating of the present invention has following characteristics: suspension, screening characteristics and shock resistance are good, resistance to elevated temperatures and heat-insulating property strengthen and reduced cost etc. greatly, are a kind of coating products that can be widely used in permanent mold casting.
The specific embodiment
The present invention is achieved like this, and at first gets cenosphere and sieves, and selects the cenosphere of granularity between 0.01～20 micron; Adopt the microwave ablution that cenosphere is carried out surface treatment then, after the processing cenosphere raw material is put into roaster and carried out roasting 1～2 hour; At last the cenosphere after the surface treatment is filled in the base-material of chill coating by predetermined ratio, fully mixes, obtain the finished product hollow microbead filling paint.
The composition of the resulting finished product hollow micro-bead added metal type coating material of the present invention comprises base-material and cenosphere, the ratio of wherein said cenosphere is between 5～40%, granularity is between 0.01～20 micron, and finished product coating can be powdery paints, solvent based coating or water paint.
The present invention adopts novel insulation material---and cenosphere joins in the common metal type coating as inserts, is made into new type of metal type thermal insulation coatings.Cenosphere (Cenosphere/Microsphere) is the nonmetal multifunctional material of a kind of lightweight, and main component is SiO
2And Al
2O
3, diameter is between 0.01～400 micron, and outward appearance is greyish white or grey, and is loose, and sphere, has hard shell at good fluidity, hollow, and wall thickness is 8～10% of its diameter.Cenosphere has characteristics such as light weight, heat-insulating property are good because the characteristic of hollow is compared with common glass microballoon, is a kind of very desirable heat-insulating material.Because its volume is less, quite or approximately greater than the fineness of paint filler, thereby can introduce the formulation for coating material system in the filler mode, make filming that coating forms have the characteristic of insulation material.Yet in present coating development, cenosphere also rarely has the people to study in the metal-type casting coating field, and research in this respect at present yet there are no report.Attempt in the present invention cenosphere is added in the chill coating, make a kind of novel thermal insulation coatings, and study of the influence of its different addition the coating heat-insulating property.
Claims (4)
