Abstract
The invention discloses a preparation method of a mould release agent used for die casting, the mould release agent comprises the following raw materials by weight: 40-50 parts of graphite, 5-10 parts of powdered steatile, 1-2 parts of polyethylene wax, 2-4 parts of boric acid, 10-20 parts of industrial alcohol and 40-60 parts of deionized water; the method comprises the following steps: weighting the raw materials according to the weight fraction, purifying the graphite, crushing to graphite powder, then placing the crushed graphite powder and weighted raw materials in a clean container, uniformly stirring, and decomposing with high speed to prepare the mould release agent. While in use, the mould release agent can be used according to the casting condition, and is diluted with water and can be sprayed by using a spray gun. The mould release agent has the advantages of simple preparation, low production cost, good demoulding effect and no corrosion effect to casting; compactness and fineness on the surface of the die casting parts can be effectively increased, and the usage life of the mold can be prolonged.
Description
Technical field
The invention belongs to chemical technology field, be specifically related to the preparation method of a kind of die casting releasing agent.
Background technology
Releasing agent is the important auxiliary material in Die Casting, closely related with piece surface fineness and die life etc., directly affects diecast parts shaping surface situation.At present, it is higher that the releasing agent used for casting using on market exists price, and it is acid or alkaline that releasing agent is, and cast(ing) surface is had to certain corrosiveness, and foundry goods was deposited after a period of time, and surface occurs mildew or the defects such as slight corrosion phenomenon occur.
Summary of the invention
The above-mentioned technical problem existing in order to overcome prior art field, the object of the invention is to, and the preparation method of a kind of die casting releasing agent is provided, and improves diecast parts surface compact and fineness, nontoxic, corrosion-free, extends die life.
The preparation method of releasing agent for die casting provided by the invention, the preparation of described releasing agent, the weight portion of its material component and each component is: graphite 40-50 part, talcum powder 5-10 part, Tissuemat E 1-2 part, boric acid 2-4 part, industrial alcohol 10-20 part, deionized water 40-60 part; Weigh every kind of raw material by the each composition weight mark of releasing agent, first graphite purification is ground into graphite powder, then stone mill powder good fragmentation and institute load weighted other raw material are poured in clean container, stir, more at a high speed releasing agent is made in decomposition.
The using method of prepared releasing agent, pours releasing agent in container into, according to the foundry goods situation of institute's die casting, adds releasing agent weight 15-60 water dilution doubly, then uses spray gun spraying.
The preparation method of releasing agent for die casting provided by the invention, its beneficial effect is, releasing agent preparation is simple, production cost is low, and stripping result is good, to the corrosion-free effect of foundry goods, effectively improve diecast parts surface compact and fineness, extended the service life of mould.
The specific embodiment
Below in conjunction with an embodiment, die casting provided by the invention is described in detail by the preparation method of releasing agent.
Embodiment
The preparation method of releasing agent for the die casting of the present embodiment, the preparation of described releasing agent, the weight portion of its material component and each component is: graphite 40-50 part, talcum powder 5-10 part, Tissuemat E 1-2 part, boric acid 2-4 part, industrial alcohol 10-20 part, deionized water 40-60 part.
Weigh every kind of raw material by the each composition weight mark of releasing agent, first take 40 parts, graphite, purification is ground into graphite powder, takes afterwards 8 parts of talcum powder, 1 part of Tissuemat E, 2 parts of boric acid, 10 parts of industrial alcohol, 40 parts of deionized waters, pour in clean container with one of the graphite powder that fragmentation is good, stir, then decompose and make releasing agent at a high speed.
When use, the made releasing agent of getting ready is poured in container, according to the foundry goods situation of institute's die casting, added the water dilution of 30 times of releasing agent weight, then use spray gun evenly to spray.
Claims (1)
1. the preparation method of a die casting use releasing agent, it is characterized in that: the preparation of described releasing agent, the weight portion of its material component and each component is: graphite 40-50 part, talcum powder 5-10 part, Tissuemat E 1-2 part, boric acid 2-4 part, industrial alcohol 10-20 part, deionized water 40-60 part; Weigh every kind of raw material by the each composition weight mark of releasing agent, first graphite purification is ground into graphite powder, then stone mill powder good fragmentation and institute load weighted other raw material are poured in clean container, stir, more at a high speed releasing agent is made in decomposition.
