Abstract
Provided are evanescent mould coating and a preparation method thereof. The preparation method of the evanescent mould coating comprises the following steps of step one, mixing 40 parts of scaly graphite powder, 60 parts of earthy graphite powder, 5 parts of activated bentonite, 10 parts of high-temperature refractory clay and 23-35 parts of water, grinding the mixture for 4 hours to obtain paste; step two, mixing 30 parts of acetic acid resin and 4 parts of rosin with 50-100 parts of water to obtain solution; and step three, putting 138-150 parts of paste and 84-134 parts of solution into a coating blender to obtain prepared evanescent mould coating. The preparation method of the evanescent mould coating has the advantage that the evanescent mould coating is prepared by the paste containing 40 parts of the scaly graphite powder, 60 parts of the earthy graphite powder, 5 parts of the activated bentonite, 10 parts of the high-temperature refractory clay and 23-35 parts of the water andthe solution containing 30 parts of the acetic acid resin, 4 parts of the rosin and 50-100 parts of the water, so that the evanescent mould coating has good air permeability, good refractoriness and high cold and hot strength.
Description
Technical field
The present invention relates to a kind of lost foam paint and preparation method thereof, relate in particular to lost foam paint of a kind of die casting production field that disappears and preparation method thereof.
Background technology
When the die casting that disappears was produced, foam can produce a large amount of gas.If the gas permeability of coating is bad, will make the foundry goods of producing produce a large amount of pores, foundry goods is scrapped.If there is not good refractoriness, will makes foundry goods produce scab, thereby cause the metalworking difficulty even scrap.If there is not good cold strength, will make the coating on the disappearance mould take place to ftracture or peel off, thereby generation scab or coating interlayer make foundry goods scrap.
Nowadays, the lost foam paint of selling on the market, price is comparatively expensive and can't satisfy the production of large-scale disappearance die casting, and performances such as the gas permeability of lost foam paint, refractoriness and cold strength still fail to reach requirement.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of good permeability, refractoriness is good and cold strength is high lost foam paint and preparation method thereof.
A kind of lost foam paint, formed by the component of following portions by weight:
Flaky graphite powder 38-42 part;
Amorphous graphite powder 58-62 part;
Active bentonite 4-6 part;
High-temperature flame-proof mud 9-11 part;
Water 70-135 part;
Rosin 3-5 part;
White glue with vinyl 28-32 part.
Preferably, formed by the component of following portions by weight:
40 parts in flaky graphite powder;
60 parts in amorphous graphite powder;
5 parts of active bentonites;
10 parts in high-temperature flame-proof mud;
Water 70-135 part;
4 parts of rosin;
30 parts of white glue with vinyl.
A kind of preparation method of lost foam paint comprises following sequential steps:
(1) flaky graphite powder, amorphous graphite powder, active bentonite and high-temperature flame-proof mud are mixed, are made into paste after adding suitable quantity of water, place grinding mill to carry out 4 hours milling then after, take out sealed storage;
(2) with white glue with vinyl and rosin dilute with water, soaked 24 hours, stir white glue with vinyl and rosin be dissolved in the water, make solution;
(3) paste of step (1) gained and the solution of step (2) gained are put into mould wash mixer by following parts by weight, stirred 2 hours, make lost foam paint:
Paste 138-150 part;
Solution 84-134 part.
Preferably, the paste in the step (1) is for being that 40 parts flaky graphite powder, 60 parts amorphous graphite powder, 5 parts active bentonite, 10 parts high-temperature flame-proof mud and the water hybrid modulation of 23-35 part form with parts by weight.
Preferably, the solution in the step (2) is for being that 30 parts white glue with vinyl and 4 parts rosin and the water hybrid modulation of 50-100 part form with parts by weight.
Beneficial effect of the present invention is: the flaky graphite powder that with parts by weight is 40 parts, 60 parts amorphous graphite powder, 5 parts active bentonite, 10 parts high-temperature flame-proof mud becomes paste with the water hybrid modulation of 23-35 part, the white glue with vinyl that with parts by weight is 30 parts becomes solution with 4 parts rosin and the water hybrid modulation of 50-100 part, the paste of 138-150 part and the solution of 84-134 part are put into mould wash mixer, stirred 2 hours, make lost foam paint, the rosin that wherein adds 4 parts makes the gas permeability of lost foam paint better, the flaky graphite powder that adds 40 parts, 60 parts amorphous graphite powder, make the refractoriness of lost foam paint better, the white glue with vinyl that adds 30 parts makes the cold strength of lost foam paint better.
