Abstract
The said binder is prepared with water, pine tar, starch, yellow sugar, manganese sulfate, calcium carbonate, PVA, borate solonchak, tung oil and sodium silicate in a certain proportion. It is non-toxic, corrosionless and pollutionless and its use makes it possible to remove sand in casting completely and to reuse sand. Its practicability enables it to be used widely in casting.
Description
The invention belongs to binding agent.
Existing binding agent is widely used in fields such as production, and there is following weak point in some binding agent wherein: the one, little poison is arranged, and user's trick has corrosion phenomenon; The 2nd, the sand removing difficulty that invests after the cast on the foundry goods is big; The 3rd, old sand is difficult to multiplexing; The 4th, increase the labour, the increase expense.
The sand cast adhesive that a kind of nontoxic, the non-corrosiveness that the objective of the invention is to avoid above-mentioned weak point of the prior art and provide, easily sand removal, old sand can continue to use.
Purpose of the present invention can realize by following measure: adopt following composition weight (%): water 60-65, and pine tar 5-8, starch 2-4, brown sugar 2-3, manganese sulfate 2-3, calcium carbonate 2-3, polyvinyl alcohol 2-4, boron coagulate native 3-5, tung oil 2-3, sodium metasilicate 12-20.
Earlier with behind starch, the borax dilute with water pulp, above-mentioned water (deduction thinned water) is heated to 35-40 ℃, add above-mentioned material (except that sodium metasilicate) successively, be heated to 100 ℃ after being stirred to abundant mixing, add sodium metasilicate when waiting again to be chilled to 30-40 ℃ after 5-10 minute, be product after stirring, encapsulate after cooling.
The present invention has following advantage compared to existing technology: the one, and this product is nontoxic, non-corrosiveness, production process non-environmental-pollution; The 2nd, the sand on casting finished products, water dash to irritate moistening after, rap come off clean; The 3rd, old sand can continue to use; The 4th, save the labour, reduce expenses.
The present invention is described in further detail below in conjunction with (embodiment):
1. take off row composition weight (%): water 62, pine tar 6, starch 3, brown sugar 2, manganese sulfate 3, calcium carbonate 2, polyvinyl alcohol 3, boron coagulates soil 4, tung oil 2, sodium metasilicate 13.
2. above-mentioned starch, boron being coagulated native dilute with water is pulpous state.
3. above-mentioned water (deduction thinned water) is heated to 40 ℃, add successively and be heated to 100 ℃ after above-mentioned material (except that sodium metasilicate) is stirred to abundant mixing, 8 minutes time, add sodium metasilicate when waiting again to be chilled to 35 ℃, be product after stirring.
4. treat the said goods cooling back encapsulation.
Claims (2)
1. sand cast adhesive is characterized in that the composition weight (%) of modulating is: water 60-65, and pine tar 5-8, starch 2-4, brown sugar 2-3, manganese sulfate 2-3, calcium carbonate 2-3, polyvinyl alcohol 2-4, boron coagulate native 3-5, tung oil 2-3, sodium metasilicate 12-20.
2. sand cast adhesive according to claim 1 is characterized in that the method for modulating is:
(1) by weight (%) takes by weighing water 60-65, pine tar 5-8, and starch 2-4, brown sugar 2-3, manganese sulfate 2-3, calcium carbonate 2-3, polyvinyl alcohol 2-4, boron coagulate native 3-5, tung oil 2-3, sodium metasilicate 12-20.
(2) above-mentioned starch, boron are coagulated native dilute with water pulp;
(3) above-mentioned water (deduction thinned water) is heated to 35-40 ℃, add successively and be heated to 100 ℃ after above-mentioned material (except that sodium metasilicate) is stirred to abundant mixing, time 5-10 minute, add sodium metasilicate when waiting again to be chilled to 30-40 ℃, be product after stirring.
(4) treat the said goods cooling back encapsulation.
