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, be specifically related to the shaggy material of a kind of solution evaporative pattern.
Background technology
Evaporative pattern work in-process, due to the impact of machined parameters, evaporative pattern sheet material moisture and weather, very easily produces particle and drops, then affect casting quality in process; Use sand papering surface in mould assembling, polishing amount is large, and efficiency is low and easily cause die size problem; Use German cold glue to repair white mould defect, increase gas forming amount and the slag making amount of foundry goods, cause the above-mentioned three kinds of problems of casting wasted product rate rising, directly affect mould usability and product quality.Make and all do not have effective way to solve surface quality problems in use.
Summary of the invention
The present invention is directed to the deficiency that prior art exists, what provide a kind of serviceability and processing performance excellence can solve the shaggy material of evaporative pattern and preparation method, the material that this invention adopts straightforward procedure to prepare effectively can solve surface quality problems, improve mold surface finish, simplify the Mold Making time.
In order to solve above technical problem, the invention provides following technical scheme:
The shaggy material of a kind of solution evaporative pattern, comprise stearic acid, paraffin, water, caustic soda, wherein the percentage composition of each component is: stearic acid 65%, paraffin 5%, water 25%, caustic soda 5%.
Meanwhile, the invention provides a kind of preparation method solving the shaggy material of evaporative pattern, comprise the steps:
Step one, contains the water into 25% in a reservoir;
Step 2, drops into paraffin, caustic soda successively when water temperature reaches about 30 DEG C;
Step 3, slows down the stearic acid pouring 65% slowly into after paraffin melting, do not stop to be stirred to and to cease fire when liquid is canescence and to continue to stir, and lotion cooling after coagulation becomes paste.
Step 4, gets out lotion, and sealed storage is for subsequent use.
Further, take out the above-mentioned material prepared on a small quantity during use, unlimited open assembly time then prohibits the use more than 3h;
Further, the gas forming amount mean value of the above-mentioned shaggy material of solution evaporative pattern prepared is 20.89ml/g, is far smaller than glue rod, white size, HA Germany import glue.
Further, the sealed storage in described step 4, for be placed in polybag by lotion, seals sack.
Technical solutions according to the invention compared with prior art, have following beneficial effect: the gas forming amount and the slag making amount that reduce foundry goods, improve casting yield; German blue glue can be replaced, reduce cost; Shorten the Mold Making cycle and improve surface quality of continuous castings.
Detailed description of the invention
In order to make those skilled in the art understand technical scheme of the present invention better, below in conjunction with specific embodiment, the present invention is described in further detail.
One of the present invention solves the shaggy material of evaporative pattern, and comprise stearic acid, paraffin, water, caustic soda, wherein the percentage composition of 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 the water into 25% in a reservoir;
Step 2, drops into paraffin, caustic soda successively when water temperature reaches about 30 DEG C;
Step 3, slows down the stearic acid pouring 65% slowly into after paraffin melting, do not stop to be stirred to and to cease fire when liquid is canescence and to continue to stir, and can use after lotion cooling after coagulation becomes paste.
Step 4, gets out lotion, sealed storage, is preferably placed in polybag, sealing sack, for subsequent use.
Further, take out the above-mentioned material prepared on a small quantity during use, unlimited open assembly time then prohibits the use more than 3h;
Further, the gas forming amount mean value of the above-mentioned shaggy material of solution evaporative pattern prepared is 20.89ml/g, is far smaller than glue rod, white size, HA Germany import glue.
The gas forming amount data of mending paste and other conventional materials are as following table:
In concrete application, adopt material of the present invention solve evaporative pattern rough surface time concrete using method be: utilize evaporative pattern sheet material composition model, the gap existed between the bonding evaporative pattern sheet material of this applying material can be used, evaporative pattern sheet material has certain defect simultaneously, the model after assembling is caused to there is the pit pit not meeting acceptance criteria, now can get the appropriate shaggy applying material of evaporative pattern that solves at places such as pit pits, use putty knife or scraper plate to press gently and strike off to process, after placing 5-8h bone dry, carry out flow coat casting.
Adopt after solving evaporative pattern shaggy materials repairing, evaporative pattern flow coat post-baking temperature can up to more than 60 DEG C, and common mending paste repair after evaporative pattern flow coat post-baking temperature generally at 50 DEG C once.Solve the shaggy material cohesion of evaporative pattern strong, by external force difficult drop-off after dry.
Above the shaggy material of solution evaporative pattern that the application provides is described in detail, apply embodiment herein to set forth the principle of the application and embodiment, the explanation of above embodiment is just for helping method and the core concept thereof of understanding the application; Meanwhile, for one of ordinary skill in the art, according to the thought of the application, all will change in specific embodiments and applications, in sum, this description should not be construed as the restriction to the application.
