Abstract
The invention discloses a kind of high thermal conductive resin sand, it is characterised in that be formulated according to following weight portion by following components：15 20 parts of furane resins；15 20 parts of phenolic resin；10 100 parts of fresh sand；6 20 parts of reclaimed sand；2 10 parts of steel ball；5 10 parts of curing agent.The present invention adds steel ball as formula medium in resin sand formula, and steel ball will bear the effect of heat conduction and load-bearing during sand processed, and after tested, after adding steel ball, integral formula thermal conductivity improves more than 30%, further lifting reverse mould production efficiency；Porous type iron shot is further added, by the air penetrability of further lifting resin sand, so as to improve the cooling velocity of the molten iron during reverse mould, improve production efficiency.
Description
Technical field
The present invention relates to resin sand field, more particularly to a kind of high thermal conductive resin sand and its production method.
Background technology
Furan resin-sand has casting quality good, the low advantage of percent defective, but it still suffers from many defects, in actual life
Need to set about in terms of its synthesis material and preparation technology etc. in product, improve its performance.Traditional resin sand will after preparation
Carry out doing mould, and add molten iron to cast；However, add molten iron process after, due to the resin sand mould heat absorption capacity of itself with
Limited strength, will cause molten iron to be difficult to the problems such as quickly cooling down, and such as relating to the resin sand mould of large-scale, because molten iron exists
Cooled and solidified will produce huge weight, so that resin sand mould endurance amount is larger, will seriously cause mould avalanche etc. to be asked
Topic.
The content of the invention
The technical problem to be solved in the present invention is：For above-mentioned the deficiencies in the prior art, there is provided a kind of high thermal conductive resin sand
And its production method.
The present invention solve its technical problem solution be：A kind of high thermal conductive resin sand, it is characterised in that by with the following group
Divide and be formulated according to following weight portion：
Furane resins 15-20 parts
Phenolic resin 15-20 parts
Fresh sand 10-100 parts
Reclaimed sand 6-20 parts
Steel ball 2-10 parts
Curing agent 5-10 parts.
A kind of method for producing above-mentioned high thermal conductive resin sand, it is characterised in that including following technique：
（1）Reclaimed sand is carried out into damaged treatment, fresh sand mixing is added, mixed sand is obtained；
（2）Mixed sand is inserted into vibro-crusher, dedusting is carried out using cyclone dust collectors and sack cleaner；
（3）Will it is broken after mixed sand be transferred to permanent-magnetic iron expeller and remove removing rust, carried out using selection by winnowing centrifugation regenerating device it is secondary
Dedusting；
（4）The bowl-type puddle mixer that is transferred to after by final dusting is carried out, and in puddle mixer add furane resins, phenolic resin,
Steel ball and curing agent, high thermal conductive resin sand is obtained after fully mixing.
As one of preferred technical scheme, it is characterised in that described iron shot is porous type iron shot.
The beneficial effects of the invention are as follows：The present invention adds steel ball as formula medium in resin sand formula, and steel ball is in system
The effect of heat conduction and load-bearing will be born during sand, after tested, after adding steel ball, integral formula thermal conductivity improves more than 30%, enters
One step lifts reverse mould production efficiency；Porous type iron shot is further added, the air penetrability of resin sand will be further lifted, from
And the cooling velocity of raising molten iron during reverse mould, improve production efficiency.
