Abstract
The resin sand of a kind of instrument casting, it includes the raw material of following parts by weight: 100 parts of matrix sand material, epoxy resin 1 ~ 3 part, 0.2 ~ 1 part of firming agent, chlorinated paraffin 0.5 ~ 2 part, alkali-free glass fibre 1 ~ 4 part, modifying agent 10 ~ 20 parts；Described matrix sand material is quartz sand and CBN abrasive material, and its mass parts ratio is 1 ~ 3:1；Described modifying agent is one or more in Gypsum Fibrosum powder, calcium bicarbonate, kaolin powder, Pulvis Talci, hydroxylapatite powder.The resin sand sand mold intensity of a kind of instrument casting 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 resin 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 resin casting technical field, be specifically related to the resin sand material of a kind of instrument casting
Material.
Background technology
Resin sand effect in Foundry Production is particularly important, and the casting wasted product caused because of the poor quality of resin sand is about
Account for the 30～50% of the total rejection number of foundry goods.Foundry Production generally requirement to resin sand is: have higher intensity and thermally-stabilised
Property, to bear the effect of various external force and high temperature；Good mobility, i.e. resin sand be sand grains under external force or action of gravity own
Between the ability that is mutually shifted；Certain plasticity, i.e. resin sand deform under external force, can keep being given after external force is removed
The ability of the shape given；Preferably breathability, i.e. resin sand hole are through the ability of gas；High knockability, also known as collapsibility,
I.e. after casting solidification, whether resin sand is easily destroyed, if the performance easily removed from foundry goods.
Casting resin sand used is required higher by instrument and equipment, and existing resin sand casting apparatus is at foundry production
In often there is various different casting flaw, such as crackle, pore, sand holes, shrinkage cavity etc., have impact on resin sand casting apparatus
Serviceability, and the generation of these defects and the caking property between foundry goods and casting resin sand, detachment are relevant, existing casting
Resin sand serviceability is poor, easily produces bonding with foundry goods, causes foundry goods to be not easily stripped, and cast breathability, plasticity
And mobility is bad, thus cause cast(ing) surface coarse so that Mechanical processing of casting percent defective is higher.
