Abstract

The water-base dissolving mould casting special-purpose coating is formed from 700-850 portions of alumina, 150-300 portions of diatomaceous earth, 20-30 portions of bentonite, 0.5-2.,0 portions of industrial sodium carbonate, 5-15 portions of cellulose sodium, 30-40 portions of white emulsion, 10-20 portions of aluminium sulfate, 20-30 portions of iron oxide, 20-30 portions of starch, 0.1-0.2 portion of washing powder and 700-800 portions of water. Said coating possesses good imbibition property, good transmutation and flowability, uniform coating layer, high strength and other advantages.

Description

Water-base paint specially for disappearing cast mold
(1) technical field
The present invention relates to a kind of water-base paint specially for disappearing cast mold, belong to chemical products.
(2) background technology
Lost foam casting is to adopt plastic foam bead analogue formation, pour into a mould under negative pressure state, molten iron replacement model position and the casting technique of cooling forming are because bubbles model is yielding in modeling process, insufficient strength, usually be coated with a coating and improve intensity, rigidity at the model outer surface, the Asia makes model combustion product and gas see through dope layer under suction function, is discharged in the molding sand, the coating gas permeability of using is bad at present, rigidity is bad, and brushability is also bad, so product quality can not guarantee.
(3) summary of the invention
Purpose of the present invention is the shortcoming and deficiency in order to overcome above-mentioned prior art just, and a kind of serviceability and the good paint specially for disappearing cast mold of processing performance are provided, thereby guarantees the high-quality of cast article.
The objective of the invention is to realize by following technical proposal:
Water-base paint specially for disappearing cast mold is characterized in that it is made by the following weight proportion raw material:
Alumine 700-850 part, diatomite 150-300 part, boron-moisten soil 20-30 part,
Industrial sodium carbonate 0.5-2.0 part, sodium cellulosate 5-15 part, white glue with vinyl 30-40 part,
Aluminum sulfate 10-20 part, iron oxide 20-30 part, starch 20-30 part, washing powder 0.1-0.2 part,
Water 700-800 part.
The granularity of described alumine is the 150-270 order, and diatomite is the 180-230 order.
Raw material of the present invention, wherein alumine and diatomite are refractory aggregates, boron-moisten soil and sodium cellulosate are suspending agent and binding agent, industrial sodium carbonate is the activator of boron-moisten soil, white glue with vinyl and starch are binding agent, and aluminum sulfate can improve the elevated temperature strength of coating, the adsorbable carbon of iron oxide, washing powder is the wellability that blowing agent can improve coating, also can add an amount of anticorrisive agent and prevent that coating is rotten.
Above-mentioned raw materials and the water grinding stirring system of mixing are formed.
Owing to take technique scheme, make the technology of the present invention compared with the prior art have following advantage and effect:
A) this coating has wellability preferably, so brushability is good;
B) have preferably and can become characteristic, trickling property is good, and coating is even;
C) good permeability, good rigidly, the intensity height, good hygroscopicity, shelling property is good;
D) effect of adsorbing carbon is arranged;
E) raw material is easy to get, and cost is low;
F) fire resistance is good;
G) wearability is good.
