Description
Technical field
The present invention relates to paint fields, and in particular to a kind of solid liquid phase two-component mixing method prepares aluminum alloy metal-type mold
The preparation of coating and spraying process.
Background technology
Water paint is widely used in the industries such as building, furniture, have many advantages, such as it is nontoxic, harmless, non-ignitable, be coating towards
The Typical Representative that green, environmentally friendly direction are developed.When traditional water paint is applied to furniture industry, performance is not ideal enough, payes attention to
The performances such as hardness, alcohol resistance, alkali resistance are had ignored while water resistance, it is ensured that water paint water resistance improves while excellent
The performances such as hardness, the alcohol resistance of water paint have larger meaning.
High-temperature resistant coating is the functional coating used in hot environment, is the typical case that coating develops towards functional direction
It represents.Currently, high-temperature resistant coating is based on organic high-temperature resistant coating.With high-temperature resistant coating application environment, performance requirement
Variation, refractory inorganic paint gradually develop, study the high-temperature resistant coating haveing excellent performance and be of great significance.
Lithium silicate aqueous solution is usually prepared by lithium salts and silicate solution reaction, has preferable mechanicalness, physicochemical stability
Deng can be used as paint binder, binder, surface conditioning agent etc..Lithium silicate aqueous solution is used for coating, and the film of formation is with resistance to
The features such as hot, water-fast, certainly dry, non-ignitable.
Invention content
The invention mainly solves the technical problem of providing a kind of solid liquid phase two-component mixing methods to prepare aluminum alloy metal-type
The preparation of die lubricant and spraying process have excellent high temperature resistance according to coating prepared by the technique.
A kind of solid liquid phase two-component mixing method prepares preparation and the spraying process of aluminum alloy metal-type die lubricant, feature
It is, solid liquid phase two-component mixing method prepares being formulated as follows for aluminum alloy metal-type die lubricant：
10-12 parts of ZnO powder screenings are uniform, by 4-5 parts of sodium silicate dissolvings in 50-60 DEG C of 90-100 part deionized waters
In, it is then slowly added into the zinc oxide by screening, is fully dissolved, is filtered after stirring evenly, obtain component A；
By 2-3 parts of kaolin of solid phase each component, 0.5-1 parts of magnesia, 1-2 parts of aluminium oxide, 0.5-1 parts of wollastonites, 0.5-1 parts of glass
The drying of glass powder, grinding, screening, obtain uniform powder, solid phase components are sufficiently stirred, and are uniformly mixed；
3-4 parts of waterglass of liquid phase, 1-2 parts of lithium silicate aqueous solutions, 0.5-1 parts of auxiliary agents are thoroughly mixed, by what is be uniformly mixed
Liquid phase is slowly dropped in solid phase, adds component A, and be stirred continuously, and the coating is made；
Spraying process is as follows：
The mold that blast finishes is preheating to 280-350 DEG C, selects a diameter of 1.3mm blackwash sprayers nozzle, selects wind pressure for 0.35-
0.4MPa, for gained coating even application on mold inner surface wall, spraying mold paint thickness is 0.15- in weighing 2 with spray gun
The mold sprayed is fitted into 350-420 DEG C of holding furnace by 0.3mm, toasts the pre- heat fixations of 1-2h；
A concentration of 14-16% of lithium silicate aqueous solution, a concentration of 18-20% of sodium silicate.
The reaction mechanism of the present invention is as follows：
Zinc oxide fusing point is high, the stable chemical performance under metal die casting temperature, and the coating containing zinc oxide has fire-retardant
Property good and good adhesiveness effect, and its fusing point is higher as coating, and when cast can reduce high temperature
Thermal losses of the liquid metals to metal mold, separates impingment corrosion of the liquid metals to cavity, avoids bonding；Lithium metasilicate it is excellent
Point is that cohesive force height, acid resistance, intensity are big, heat-resist etc.；It is with kaolin, magnesia, aluminium oxide, wollastonite, glass powder
Solid phase prepares aluminum alloy metal-type using waterglass, lithium silicate aqueous solution, auxiliary agent as liquid phase using solid liquid phase two-component mixing method
Die lubricant, high temperature resistance are excellent.
Specific implementation mode
In order to make the technical means, the creative features, the aims and the efficiencies achieved by the present invention be easy to understand, tie below
Specific embodiment is closed, the present invention is further explained.
