Abstract
The instrument resin casting of a kind of feature of environmental protection, it includes the raw material of following parts by weight: 100 parts of reclaimed sand material, modified furan resin 1 ~ 3 part, 0.2 ~ 1 part of firming agent, modified add auxiliary agent 10 ~ 20 parts；The described modified auxiliary agent that adds is one or more in Gypsum Fibrosum powder, Kaolin, meerschaum, pitchstone, lignosulfonate fiber.The instrument resin casting sand mold intensity of a kind of feature of environmental protection that the present invention prepares is high, dimensional discrepancy is little, collapsibility good, energy resource consumption is few, and the feature of environmental protection is excellent simultaneously, can be used for the production casting of various molding sand instrument foundry goods, and the surface quality of foundry goods and dimensional accuracy are high.
Description
Technical field
The present invention relates to a kind of moulding sand for casting technical field, be specifically related to the instrument casting resin of a kind of feature of environmental protection
Sand.
Background technology
Molding sand effect in Foundry Production is particularly important, and the casting wasted product caused because of the poor quality of molding sand accounts for casting
The 30～50% of the total rejection number of part.Foundry Production generally requirement to molding sand is: have higher intensity and heat stability, to hold
Acted on by various external force and high temperature；Good mobility, i.e. molding sand are mutually moved between sand grains under external force or action of gravity own
Dynamic ability；Certain plasticity, i.e. molding sand deform under external force, the shape that can keep being given after external force is removed
Ability；Preferably breathability, i.e. molding sand hole are through the ability of gas；High knockability, also known as collapsibility, i.e. at casting solidification
Whether rear molding sand is easily destroyed, if the performance easily removed from foundry goods.
Casting sand used is required higher by instrument and equipment, existing molding sand casting apparatus warp in foundry production
Various different casting flaw often can occur, such as crackle, pore, sand holes, shrinkage cavity etc., have impact on the usability of molding sand casting apparatus
Can, and the generation of these defects and the caking property between foundry goods and casting sand, detachment are relevant, existing casting sand uses
Poor-performing, easily produces bonding with foundry goods, causes foundry goods to be not easily stripped, and cast breathability, plasticity and mobility not
Good, thus cause cast(ing) surface coarse so that Mechanical processing of casting percent defective is higher.
Summary of the invention
Not enough for prior art, the invention provides the instrument resin casting that a kind of high-performance, the feature of environmental protection are good.
The present invention solves the technical scheme of above-mentioned technical problem employing: the instrument resin casting of a kind of feature of environmental protection,
Raw material including following parts by weight: 100 parts of reclaimed sand material, modified furan resin 1 ~ 3 part, 0.2 ~ 1 part of firming agent, modified interpolation
Auxiliary agent 10 ~ 20 parts；
Described modified add auxiliary agent be the one in Gypsum Fibrosum powder, Kaolin, meerschaum, pitchstone, lignosulfonate fiber or
Several.
Further, the instrument resin casting of described a kind of feature of environmental protection, including the raw material of following parts by weight: regeneration
100 parts of sand material, modified furan resin 2 parts, 0.5 part of firming agent, modified interpolation auxiliary agent 15 parts；The described modified auxiliary agent that adds is stone
Cream powder, Kaolin pitchstone and lignosulfonate fiber.
Further, the instrument resin casting of described a kind of feature of environmental protection, including the raw material of following parts by weight: regeneration
100 parts of sand material, modified furan resin 1 part, 0.2 part of firming agent, modified interpolation auxiliary agent 10 parts；The described modified auxiliary agent that adds is stone
Cream powder and pitchstone.
Further, the instrument resin casting of described a kind of feature of environmental protection, including the raw material of following parts by weight: regeneration
100 parts of sand material, modified furan resin 3 parts, 1 part of firming agent, modified interpolation auxiliary agent 20 parts；The described modified auxiliary agent that adds is Gypsum Fibrosum
Powder, Kaolin, meerschaum, pitchstone and lignosulfonate fiber.
Compared with prior art, what the present invention possessed has the beneficial effect that
The instrument resin casting sand mold intensity of a kind of feature of environmental protection that the present invention prepares is high, dimensional discrepancy is little, collapsibility good, energy
Source consumes few, uses the reclaimed sand material feature of environmental protection excellent, concurrently facilitates the cost reducing resin sand；The resin sand of the present invention can be used
Production in various molding sand instrument foundry goods casts, and the surface quality of foundry goods and dimensional accuracy are high.
