Abstract
The invention discloses a kind of preparation method of cast paint, is related to casting technology field, includes the raw material of following parts by weight：50~60 parts of zirconium English powder, 20~25 parts of forsterite powder, 8~12 parts of bauxite, 6~10 parts of activated bentonite, 0.8~1.2 part of this quality sulfoacid calcium, 2~3 parts of Ludox, 0.1~0.2 part of sodium sulphate, 2~3 parts of white glue with vinyl；Comprise the following steps that：A, raw material is weighed；B, zirconium English powder, forsterite powder, bauxite are put into mixed machine, it is mixed to obtain mixed resin；C, activated bentonite, this quality sulfoacid calcium, Ludox, sodium sulphate, white glue with vinyl are added into mixed resin, adds water mixed；D, step C resulting materials are poured into agitator, adds water to adjust Baume degrees after stirring.Compared with prior art, the cast paint adhesive force that prepared by the present invention is strong, has good gas permeability and higher surface strength, is produced for lost foam casting, cast(ing) surface is bright and clean, quality of finished product good.
Description
Technical field
The present invention relates to casting technology field, the preparation side of especially a kind of cast paint for lost foam casting production
Method.
Background technology
Cast paint refers to for coated in die cavity and core surface, to improve its surface refractoriness, chemical stability, anti-
The casting auxiliary material of the performances such as metal erosion, anti-stick grittiness.With technological progress and production development, casting quality is wanted
Also more and more higher, the especially visual quality of casting is asked increasingly to be paid close attention to by casting circle and casting using enterprise.Cast paint
Due in close relations with casting quality, particularly surface quality of continuous castings, application is also more and more extensive.Presently used cast paint
Adhesive force and gas permeability is poor, surface strength is low, easily causes the defects of casting produces viscous sand, sand holes, stomata, slag inclusion.
The content of the invention
Problem to be solved by this invention is to provide a kind of preparation method of cast paint, can solve existing method preparation
Cast paint adhesive force and poor air permeability, the problem of surface strength is low.
In order to solve the above problems, the technical solution adopted by the present invention is：The preparation method of this cast paint, including under
The raw material of row parts by weight：50~60 parts of zirconium English powder, 20~25 parts of forsterite powder, 8~12 parts of bauxite, activated bentonite 6~
10 parts, 0.8~1.2 part of this quality sulfoacid calcium, 2~3 parts of Ludox, 0.1~0.2 part of sodium sulphate, 2~3 parts of white glue with vinyl；
Comprise the following steps that：
A, raw material is weighed by the parts by weight of above-mentioned each raw material, it is standby；
B, zirconium English powder, forsterite powder, bauxite are put into mixed machine, mixed 10~20 minutes, obtain mixed resin；
C, activated bentonite, this quality sulfoacid calcium, Ludox, sodium sulphate, white glue with vinyl, Ran Houjia are added into gained mixed resin
Enter the water of gross weight 30~40%, mixed 50~60 minutes；
D, step C resulting materials are poured into agitator, it is 65~70 to add water to adjust Baume degrees after stirring 2~3 hours, produces this
Cast paint.
In the preparation method technical scheme of above-mentioned cast paint, more specifically technical scheme can also be：The agitator
Rotating speed be 1450~1800 revs/min.
By adopting the above-described technical solution, the present invention has the advantages that compared with prior art：
Cast paint adhesive force prepared by the present invention is strong, has good gas permeability and higher surface strength, for evaporative pattern
Foundry Production, casting is avoided to produce the defects of gluing sand, sand holes, stomata, slag inclusion, cast(ing) surface is bright and clean, quality of finished product good.
