Abstract
The invention relates to a material capable of eliminating evaporative pattern surface roughness and a preparation method thereof. The material capable of eliminating evaporative pattern surface roughness comprises stearic acid, paraffin wax, water and sodium hydroxide. The preparation method of the material capable of eliminating evaporative pattern surface roughness comprises the following steps that firstly, 25% of water is poured into a container; secondly, the paraffin wax and the sodium hydroxide are sequentially added into the water after the temperature of the water reaches 30 DEG C or so; thirdly, after the paraffin wax melts, 65% of stearic acid is slowly poured into the water and stirred continuously, fire is stopped and stirring is continued until liquid becomes grey white, and pasty fluid cools and then solidifies into paste; and fourthly, the paste is scooped out of the container and stored in a sealed mode, optimally, the paste is placed into a plastic bag, and the bag opening is sealed for standby application. By means of the technical scheme, the material and the preparation method have the following beneficial effects that the gas-forming amount and slagging amount of castings are reduced, and the rate of finished casting products is increased; the material can replace Germany blue gel, so cost is lowered; the mold manufacturing period is shortened, and the surface quality of the castings is improved.
Description
Technical field
The invention belongs to chemical material field, and in particular to one kind solves the shaggy material of evaporative pattern.
Background technology
Evaporative pattern work in-process, due to the impact of machined parameters, disappearance template material moisture and weather, in the course of processing
Easily produce granule to drop, casting quality is affected then；Sand papering surface used in mould assembling, polishing amount is big, and efficiency is low
And easily cause die size problem；White mould defect is repaired using German cold glue, increases the gas forming amount and slag making amount of foundry goods, caused
Casting wasted product rate rises above-mentioned three kinds of problems, directly affects mould usability and product quality.Make and do not have in use
Effect method solves surface quality problems.
The content of the invention
The present invention is in view of the shortcomings of the prior art, there is provided a kind of performance and processing performance is excellent can solve
The certainly shaggy material of evaporative pattern and preparation method, this invention can effectively solve the problem that using the material that straightforward procedure is prepared
Surface quality problems, improve mold surface finish, simplify the Mold Making time.
In order to solve above technical problem, the present invention provides technical scheme below：
One kind solves the shaggy material of evaporative pattern, including stearic acid, paraffin, water, Caustic soda, wherein the hundred of each component
Point content is：Stearic acid 65%, paraffin 5%, water 25%, Caustic soda 5%.
Meanwhile, the invention provides a kind of preparation method for solving the shaggy material of evaporative pattern, comprises the steps：
Step one, contains in a reservoir the water into 25%；
Step 2, puts into successively paraffin, Caustic soda when water temperature reaches 30 DEG C or so；
Step 3, it is paraffin melting after slow down the stearic acid for pouring 65% into slowly, do not stop to be stirred to liquid and cease fire simultaneously in during canescence
Continue to stir, after mastic cooling paste is frozen into.
Step 4, mastic is got out, and sealed storage is standby.
Further, a small amount of above-mentioned material for preparing is taken out when using, open assembly time is opened wide and is then forbidden making more than 3h
With；
Further, the gas forming amount meansigma methodss of the above-mentioned shaggy material of solution evaporative pattern for preparing are
Chewing gum enters in 20.89ml/g, far smaller than glue stick, white size, HA Germany.
Further, the sealed storage in the step 4 is that mastic is placed in plastic bag, seals bag mouth.
Technical solutions according to the invention compared with prior art, have the advantages that：Reduce getting angry for foundry goods
Amount and slag making amount, improve casting yield；German indigo plant glue can be replaced, cost is reduced；Shorten the Mold Making cycle simultaneously
Improve surface quality of continuous castings.
Specific embodiment
In order that those skilled in the art more fully understand technical scheme, with reference to specific embodiment to this
Invention is described in further detail.
One kind of the present invention solves the shaggy material of evaporative pattern, including stearic acid, paraffin, water, Caustic soda, its
The percentage composition of middle each component is：Stearic acid 65%, paraffin 5%, water 20%-25%, Caustic soda 5%.
The preparation method of the shaggy material of above-mentioned solution evaporative pattern, comprises the steps：
Step one, contains in a reservoir the water into 25%；
Step 2, puts into successively paraffin, Caustic soda when water temperature reaches 30 DEG C or so；
Step 3, it is paraffin melting after slow down the stearic acid for pouring 65% into slowly, do not stop to be stirred to liquid and cease fire simultaneously in during canescence
Continue to stir, use by being frozen into after paste after mastic cooling.
Step 4, mastic is got out, sealed storage, in being preferably positioned at plastic bag, seals bag mouth, standby.
Further, a small amount of above-mentioned material for preparing is taken out when using, open assembly time is opened wide and is then forbidden making more than 3h
With；
Further, the gas forming amount meansigma methodss of the above-mentioned shaggy material of solution evaporative pattern for preparing are
Chewing gum enters in 20.89ml/g, far smaller than glue stick, white size, HA Germany.
The gas forming amount data such as following table of mending paste and other conventional materials：
In specific application, specifically used method when adopting the material of the present invention to solve evaporative pattern rough surface for：
Using disappearance template material composition model, it is possible to use the gap existed between the applying material bonding disappearance template material, while disappearing
Losing template material has certain defect, causes the model after assembling to there is the pit pit for not meeting acceptance criteria, now can take suitable
Amount solves the shaggy applying material of evaporative pattern in pit pit etc., and place is pressed lightly on and struck off using putty knife or scraper plate
Reason, placing after 5-8h is completely dried carries out flow coat casting.
Using solving after the shaggy materials repairing of evaporative pattern, evaporative pattern flow coat post-baking temperature can be up to 60 DEG C with
On, and the evaporative pattern flow coat post-baking temperature after common mending paste is repaired typically at 50 DEG C once.Solve evaporative pattern rough surface
Material cohesion it is strong, it is difficult for drop-off by external force after being dried.
The shaggy material of solution evaporative pattern provided herein is described in detail above, it is used herein
Embodiment is set forth to the principle and embodiment of the application, and the explanation of above example is only intended to help and understands this
The method and its core concept of application；Simultaneously for one of ordinary skill in the art, according to the thought of the application, concrete
