Abstract
The invention discloses a kind of lost foam casting coating, by weight, including following component：0.2 0.4 parts of 50 60 parts of silica flour, 12 parts of plant gum powder, 10 15 parts of kaolin, 68 parts of bentonite, 46 parts of methyl methacrylate, 12 parts of polychloroprene latex and catalyst.The lost foam casting coating of the structure, with the preferable advantage of adhesive force, being coated with property and levelability.
Description
Technical field
The present invention relates to a kind of lost foam casting coating.
Background technology
Lost foam casting is described as " 21 century casting technology " and " green casting technology ", in casting iron field extensive use
And popularization, casting quality is greatly improved so that client expects constantly enhancing to steel-casting quality, promotes cast steel enterprise outstanding
It is more and more that it is that medium-sized and small enterprises put into terms of Technology of EPC.Technology of EPC be by with casting dimension shape
The similar foamed plastic model of shape is bonded and is combined into model cluster, after brushing refractory coating and drying, is embedded in vibration in drystone sand
Moulding, pours into a mould liquid metals under certain condition, model is gasified and occupies modal position, and required casting is formed after solidification cooling
Method.Compared with traditional foundry engieering, due to making model using the foamed plastics for easily gasifying, without modulus and making
Core rod, without die joint, thus non-trimming burr, it is dirty that the technical process has abandoned traditional handicraft complex procedures, the course of work completely
The dye unfavorable factor that thing discharge capacity is big, labor strength is high, is accomplished that a kind of operation is simple, and efficiency high is near non-harmful
Clean manufacturing.Production line is simple and practical, small investment, is especially suitable for the technological transformation of old factory building, and infrastructure mainly falls in knockout
And the sand treatment Ministry of worker, therefore construction area and construction volume are less.Multiple operation system can be used, can be worked using the stage again
System, production line operation is simple, and management is easy.Strong applicability, without worrying eliminating for old product, as long as product casting newly developed
Width can be produced on line in certain scope.
The fireproof coating for using at present, its adhesive force, being coated with property and levelability are poor.
The content of the invention
In view of this, it is an object of the invention to provide a kind of lost foam casting coating, make it have adhesive force, being coated with property with
And the preferable advantage of levelability.
The present invention by following technological means solution above-mentioned technical problem, a kind of lost foam casting coating, by weight,
Including following component：Silica flour 50-60 parts, plant gum powder 1-2 parts, kaolin 10-15 parts, bentonite 6-8 parts, methacrylic acid
Methyl esters 4-6 parts, polychloroprene latex 1-2 parts and catalyst 0.2-0.4 parts.
Further, the catalyst is potassium peroxydisulfate-sodium hydrogensulfite, dibenzoyl peroxide-N, N- dimethylanilines
With one or more in hydrop diisopropylbenzene (DIPB)-TEPA, and the catalyst oxidant constituents with reduction
Agent constituent mass ratio is 1-2:1.
Further, the plant gum powder is any one of cornstarch, farina and tapioca.
Beneficial effects of the present invention：The invention discloses a kind of lost foam casting coating, by weight, including such as the following group
Point：Silica flour 50-60 parts, plant gum powder 1-2 parts, kaolin 10-15 parts, bentonite 6-8 parts, methyl methacrylate 4-6 parts,
Polychloroprene latex 1-2 parts and catalyst 0.2-0.4 parts.The lost foam casting coating of the structure, using methyl methacrylate with
Polychloroprene latex is reacted, and the introducing of soft monomer in polychloroprene latex, film-forming temperature is significantly reduced, initial bonding strength enhancing, meets various weathers
Use requirement；Generation redox reaction, with the preferable advantage of adhesive force, being coated with property and levelability.
