Abstract
The invention relates to instrument casting resin sand enhanced by alkali free glass fibers. The instrument casting resin sand is prepared from the following raw materials in parts by weight: 100 parts of a basal body sand material, 1-3 parts of thermoplastic phenolic resin, 0.2-1 part of a curing agent, 0.05-0.1 part of a coupling agent, 1-4 parts of alkali free glass fibers, and 10-20 parts of a modifying addition agent, wherein the basal body sand material is quartz sand and bauxite sand in the mass ratio of the quartz sand to the bauxite sand being (1-3) to1; and the modifying addition agent is one or several kinds of gypsum powder, kaolin, sepiolite, pitchstone, and hydroxyapatite powder. The produced instrument casting resin sand enhanced by the alkali free glass fibers is high in sand mold intensity, small in dimension deviation, good in collapsibility, and low in energy consumption; and besides, the instrument casting resin sand is favorable in environmentally-friendly performance, and can be used for production and casting of various resin sand instrument casts. The surface quality and the dimension precision of the casts are high.
Description
Technical field
The present invention relates to a kind of resin casting technical field, be specifically related to the instrument that a kind of alkali-free glass fibre strengthens
Casting resin sand.
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.
