Abstract
A kind of expansible graphite alcohol-base foundry coating, following material by weight：Magnesia powder 30 40, titanium dioxide 23, acrylic resin 0.4 0.7, expansible graphite 30 45, aluminium hydroxide 13, hexadecyltrimethylammonium chloride 0.3 0.7, lychee leaf 10 13, linseed oil 13, phenolic resin 35, hexa 36, ethanol 45 67；Cost of the present invention is low, energy-conserving and environment-protective, and by optimized production process flow and formula, obtained coating has the advantages that high temperature resistant, intensity are high, gas permeability is good.
Description
Technical field
The present invention relates to cast paint field, and in particular to a kind of expansible graphite alcohol-base foundry coating.
Background technology
Cast paint refers to for coated in die cavity or core surface, to change its surface refractoriness, chemical stability, anti-
The casting auxiliary material of the performances such as metal erosion, anti-stick grittiness, the disperse system that it is made up of the different material of a variety of properties,
It, which is formed, mainly includes the composition such as refractory material, suspending agent, carrier, binding agent and special additive.Required when acting on casting
Coating have good processing performance, service behaviour, quality stability and apply reappearance, on the one hand can play it is heat-insulated,
Weigh temperature, exempts the purpose of the impingment corrosion of molten metal, cast product on the other hand can be prevented because Local cooling is too fast and
Caused by cracking, sand holes, white iron formation the defects of.Cast paint species is various, can substantially be divided into two classes：Water based paint and
Alcohol-base paint.Wherein alcohol-base paint was ignited both curable after application, was not required to dry, and can shorten the production cycle, simplified technique,
Drying plant investment is reduced, is to be cast a kind of widely used quick drying paint in boundary, is widely used to steel, iron, coloured casting
Production in.
The content of the invention
The technical solution adopted for the present invention to solve the technical problems is：A kind of expansible graphite alcohol-base foundry coating, its
It is characterized in, it is made from the following raw materials in parts by weight：Magnesia powder 30-40, titanium dioxide 2-3, acrylic resin 0.4-0.7, can
Expanded graphite 30-45, aluminium hydroxide 1-3, hexadecyltrimethylammonium chloride 0.3-0.7, lychee leaf 10-13, linseed oil 1-3,
Phenolic resin 3-5, hexa 3-6, ethanol 45-67.
The beneficial effects of the invention are as follows：Cost of the present invention is low, energy-conserving and environment-protective, by optimized production process flow and formula,
Obtained coating has the advantages that high temperature resistant, intensity are high, gas permeability is good.
Embodiment
Specific embodiment：A kind of expansible graphite alcohol-base foundry coating, it is characterized in that, it by following parts by weight raw material system
Into：Magnesia powder 30-40, titanium dioxide 2-3, acrylic resin 0.4-0.7, expansible graphite 30-45, aluminium hydroxide 1-3,16
Alkyl trimethyl ammonium chloride 0.3-0.7, lychee leaf 10-13, linseed oil 1-3, phenolic resin 3-5, hexa 3-6, second
Alcohol 45-67.
The beneficial effects of the invention are as follows：Cost of the present invention is low, energy-conserving and environment-protective, by optimized production process flow and formula,
Obtained coating has the advantages that high temperature resistant, intensity are high, gas permeability is good.
Obviously, above-described embodiment is only intended to clearly illustrate example, and is not the restriction to embodiment.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of change or
Change.There is no necessity and possibility to exhaust all the enbodiments.And the obvious change thus extended out or
Among changing still in the protection domain of the invention.
