Abstract
The invention discloses high-strength graphite paste painting, which comprises the following components in part by weight: 60 to 80 parts of graphite powder, 10 to 30 parts of quartz sand, 5 to 15 parts of stainless steel fiber, 1 to 5 parts of sodium carboxymethylcellulose mixture and the balance of water and also comprises strengthening paste in an amount of 5 to 15 percent based on the mass of the high-strength graphite paste painting, wherein the strengthening paste comprises the following components in part by weight: 20 to 40 parts of ferric oxide powder, 10 to 20 parts of acrylic resin, 10 to 20 parts of acetic acid and 40 to 60 parts of magnesium powder; and the sodium carboxymethylcellulose mixture comprises the following components in part by weight: 10 to 20 parts of sodium carboxymethylcellulose, 5 to 15 parts of polyethylene and the balance of water. The high-strength graphite paste painting has the advantages of simple component, simple and easy preparation operation, relatively high strength, easy uniform blending, relatively high adhesion and high roughness.
Description
Technical field
The present invention relates to a kind of coating, relate in particular to a kind of high strength type oildag coating, specifically be applicable to the smearing of surfaces externally and internally of the foundry sand type of big foundry goods.
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, the patent of invention that open day is on February 23rd, 1994 discloses and planted with graphite powder, zirconium English powder, high-alumina fly, titanium slag powder etc. is refractory powder, 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 certain intensity, and hand is touched, ash is not all fallen in air-blowing, and 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 is difficult for mixing, cohesive a little less than, in addition, intensity is relatively poor, is not suitable for the casting of heavy castings, otherwise easily breaks.
Summary of the invention
The objective of the invention is to overcome that the composition that exists in the prior art is too complicated, formulation operations is loaded down with trivial details, be difficult for mixing, cohesive is weak, relatively poor defective and the problem of intensity, provide that a kind of composition is simple, formulation operations is simple and easy, easily mix, cohesive is strong, intensity high strength type oildag coating preferably.
For realizing above purpose, technical solution of the present invention is: a kind of high strength type oildag coating, and its constituent and weight portion ratio thereof are: graphite powder 60-80, quartz sand 10-30, stainless steel fibre 5-15, sodium carboxymethylcellulose mixture 1-5, all the other are water.
The constituent and the weight portion ratio thereof of described high strength type oildag coating are: graphite powder 70, and quartz sand 20, stainless steel fibre 10, sodium carboxymethylcellulose mixture 3, all the other are water.
Also comprise a kind of reinforcement cream in the described high strength type oildag coating, the mass percent that this reinforcement cream accounts for high strength type oildag coating is 5-15%.
The constituent of described reinforcement cream and weight portion ratio thereof are: brown iron oxide 20-40, acrylic resin 10-20, acetic acid 10-20, magnesia powder 40-60.
The constituent of described reinforcement cream and weight portion ratio thereof are: brown iron oxide 30, acrylic resin 15, acetic acid 15, magnesia powder 50.
The constituent of described sodium carboxymethylcellulose mixture and weight portion ratio thereof are: sodium carboxymethylcellulose 10-20, and polyethylene 5-15, all the other are water.
Compared with prior art, beneficial effect of the present invention is:
1, owing to constituent and weight portion ratio thereof in a kind of high strength type oildag of the present invention coating are: graphite powder 60-80, quartz sand 10-30, stainless steel fibre 5-15, sodium carboxymethylcellulose mixture 1-5, all the other are water, main raw material(s) has only four kinds, kind is less, is easy to preparation.Therefore composition of the present invention is simple, formulation operations is simple and easy.
2, owing to comprised quartz sand and stainless steel fibre in a kind of high strength type oildag of the present invention coating, both can both improve intensity of the present invention greatly for this, especially stainless steel fibre, can also improve toughness of the present invention, and, the present invention also comprises reinforcement cream, its constituent and weight portion ratio thereof are: brown iron oxide 20-40, acrylic resin 10-20, acetic acid 10-20, magnesia powder 40-60, this reinforcement cream not only self has certain intensity, bigger effect is that the various materials among the present invention are carried out high strength to be mixed, and makes the density of mixed coating bigger, has higher strength and toughness, in addition, the sodium carboxymethylcellulose of more content helps strengthening the mixing of cream in the sodium carboxymethylcellulose mixture, thereby helps even mixing of the present invention, and then gives full play to the characteristics of high strength and high tenacity.So the present invention not only easily mixes, cohesive is stronger, and intensity is big, toughness is better.
