Abstract
Disclosed is a manufacturing technology of a lost foam mold model coating. The manufacturing technology comprises the steps of three-time coating. When coating is conducted for the first time, hanging coating operation is conducted by the use of a coating material in a drying room for twelve hours, and the temperature of the drying room is 35 DEG C, wherein the coating material is made of white aluminum powder, quartz powder, white latex, cellulose and anhydrous sodium carbonate in a mixed mode. When coating is conducted for the second time, hanging coating operation is conducted by the use of a coating material in the drying room for twenty-four hours, and the temperature of the drying room is 55 DEG C, wherein the coating material is made of bauxite, quartz powder and an adhesive in a mixed mode, and water is added to the bauxite, the quartz powder and the adhesive. When coating is conducted for the third time, the used coating material is the same as the coating material used by coating for the second time, the temperature of the drying room is 50 DEG C, hanging coating operation is conducted for forty-eight hours, then slow drying is conducted to enable chlorine to be exhausted, and therefore bubbles are not prone to being generated when pouring is conducted. The manufacturing technology has the advantages that the bubbles are not prone to being generated when pouring is conducted, and the product can be high in glossiness and free of burnt-on sand due to three-time hanging coating operation of a lost foam mold.
Description
Technical field
The present invention relates to a kind of manufacture craft of lost foam pattern coating.
Background technology
At present, the mould that is applicable to of the founder of traditional evaporative pattern: casting pig--nonferrous alloy--common straightcarbon steel--spheroidal graphite cast-iron--mild steel and steel alloy; Adopt common process: foaming plastic bead, prefoam, pattern molding foams, and apperance combines, brushing paint, moulding, cast, and fall sand; There is many defects due to the reason of mold materials itself and the reason of technique itself in the mould produced like this, as: be easy to when pouring into a mould produce bubble.
The glossiness of product is bad and scab is many.
Summary of the invention
For solving the problem in background technology, the invention provides a kind of lost foam pattern coated coating and manufacture craft thereof, thus solution is easy to when pouring into a mould produce bubble; And the bad and technical problem that scab is many of the glossiness of product.
A manufacture craft for lost foam pattern coating, comprises the step of three coatings:
First time coating, use the coating be mixed by white aluminium powder, silica flour, white glue with vinyl, cellulose, natrium carbonicum calcinatum in drying room, to hang painting 12 hours, drying room temperature is 35 DEG C;
Second time coating, use by bauxite, silica flour, adhesive, the coating mixed that adds water hangs painting 24 hours in drying room, and drying room temperature is 55 DEG C;
Third time coating, the coating of use is identical with the last time, and drying room temperature is 50 DEG C, hangs painting 48 hours, then dries slowly, chlorine is discharged, and makes so not easily to produce bubble when pouring into a mould.
Preferably, when first time applies, the weight portion of each component is, white aluminium powder 70 parts, silica flour 40 parts, white glue with vinyl 2 parts, cellulose 0.5 part, natrium carbonicum calcinatum 0.01 part.
Preferably, during second and third coating, the weight portion of each component is, bauxite 20 parts, silica flour 30 parts, and 6 parts, adhesive, mixes with the water of 44 parts.
Further, 200 mesh sieves crossed by described silica flour.
Described method need be hung through 3 times and is coated with evaporative pattern.Hang through 3 times and be coated with, have and make product glossiness good, without the Advantageous Effects of scab.
The present invention not easily produces bubble when having cast and hangs through 3 times and is coated with evaporative pattern, makes product glossiness good, without scab.
Detailed description of the invention
Understand below technical scheme of the present invention to make those skilled in the art that the invention will be further described better:
Embodiment one:
A manufacture craft for lost foam pattern coating, step is as follows:
First time coating, use by white aluminium powder 70 parts, 200 order stone silica flours 40 parts, white glue with vinyl 2 parts, cellulose 0.5 part, natrium carbonicum calcinatum 0.01 part of coating be mixed hangs painting 12 hours in drying room, and drying room temperature is 35 DEG C;
Second time coating, use by bauxite 20 parts, 200 order silica flours 30 parts, 6 parts, adhesive, the coating that the water with 44 parts mixes hangs painting 24 hours in drying room, and drying room temperature is 55 DEG C;
Third time coating, the coating of use is identical with the last time, and drying room temperature is 50 DEG C, hangs painting 48 hours, then dries slowly, chlorine is discharged, and makes so not easily to produce bubble when pouring into a mould.
Described method need be hung through 3 times and is coated with evaporative pattern.Hang through 3 times and be coated with, have and make product glossiness good, without the Advantageous Effects of scab.
The present invention not easily produces bubble when having cast and hangs through 3 times and is coated with evaporative pattern, makes product glossiness good, without scab.
Mode above only by illustrating describes some one exemplary embodiment of the present invention, undoubtedly, for those of ordinary skill in the art, when without departing from the spirit and scope of the present invention, can revise described embodiment by various different mode.Therefore, foregoing description is illustrative in itself, should not be construed as the restriction to the claims in the present invention protection domain.
