Technical field
The present invention relates to a kind of coating, relate in particular to a kind of fire safe type silica flour mending paste, specifically be applicable to the repairing of the surfaces externally and internally of foundry sand type.
Background technology
Fast development along with foundry industry, requirement to the casting workpiece surface quality is more and more higher, requirement to the sand mold surface coating also strengthens thereupon, generally all necessarily require quality homogeneous, good, the water-fast hear resistance of caking property strong, and stable in properties under normal temperature and high pressure, be easy to brushing, when casting, can reach defectives such as preventing scab, burning into sand, thereby obtain the foundry goods of any surface finish.
The Chinese patent publication number is CN1082466A, it is refractory powder with graphite powder, zirconium English powder, high-alumina fly, titanium slag powder etc. that the patent of invention that open day is on February 23rd, 1994 discloses a kind of, bentonite, Ludox, calgon, CMC, kaolin are suspending agent and binding agent, and the water based paint that is mixed with of di-iron trioxide, chaff alcohol and water, its rheological characteristic, suspension, gas-forming property, anti-cracking behavior, high-temperature stability are all good after testing.Though should invent in casting is used, coating has higher-strength, hand is touched, ash is not all fallen in air-blowing, its inside and outside sur-face peeling is effective behind the casting falling sand, but its composition is too complicated, formulation operations is loaded down with trivial details, and cohesive is weak, fire resistance is not strong, is not suitable for the surfaces externally and internally of foundry sand type is repaired.
Summary of the invention
The objective of the invention is to overcome defective and the problem that composition is too complicated, formulation operations is loaded down with trivial details, cohesive is weak, fire resistance is not strong that exist in the prior art, the fire safe type silica flour mending paste that a kind of composition is simple, formulation operations is simple and easy, cohesive is strong, fire resistance is stronger is provided.
For realizing above purpose, technical solution of the present invention is: a kind of fire safe type silica flour mending paste, and its constituent and weight portion ratio thereof are: silica flour 70-80, diatomite 5-15, sodium carboxymethylcellulose 2-6, polyvinyl alcohol mixture 2-4, refractory particle 20-40, all the other are water.
