Abstract
A furan resin self curing sand comprises a primary sand, an adhesive, a curing agent and a lubricating agent, wherein the dosage of the curing agent is 40- 60% of that of the adhesive; the dosage of the adhesive is 3 to 5 percent of that of the primary sand; the dosage of the lubricating agent is 2 to 4 percent of that the primary sand; and the curing agent is a mixture of high acid and low acid. The high acid comprises the following components in part by weight: 40 to 60 parts of sulphuric acid, 30 to 40 parts of phosphoric acid and remainder part of water; the low acid comprises the following components in part by weight: 10 to 20 parts of sulphuric acid, 20 to 30 parts of phosphoric acid and remainder part of water. The furan resin self curing sand provided by the invention has the advantages of higher intensity, good tenacity, cheap price and lower production cost.
Description
Technical field
The present invention relates to a kind of self-hardening sand, relate in particular to a kind of furan resin self curing sand, specifically be applicable to the furan resin self curing sand that the alloy sand mold casting is adopted.
Background technology
Resin self-setting sand is generally formed by mixed preparing such as silica sand, resin and curing agents.Resin commonly used has furane resins, resol and urethane resin.The sand mold intensity height made from this molding sand, size is accurate, collapsibility good, energy resource consumption is few, can be used for the production of cast steel, cast iron and cast nonferrous alloy foundry goods, the surface quality of foundry goods and dimensional accuracy height.Resin self-setting sand is a kind of rising moulding sand.
The Chinese patent Granted publication number is CN1216703C, Granted publication day is that the patent of invention on August 31st, 2005 discloses a kind of self-hardening sand that belongs to casting industry, it is a kind of environment-friendly type self-hardening sand, pollution-free, collapsibility is good, tolerance is high, gas-forming property is little, and the foundry goods physical dimension is accurate, and, with low cost, method of operating is easy, can be widely used in whole casting industries such as automobile spare, radiator, bent axle, lathe, lathe.Though the self-hardening sand of this Invention Announce is pollution-free, collapsibility good, tolerance is high, its toughness is relatively poor, fragility is bigger, in use breaks easily.
Summary of the invention
The objective of the invention is to overcome the toughness that exists in the prior art is relatively poor, fragility is bigger defective and problem, provide that a kind of toughness is big, the less furan resin self curing sand of fragility.
For realizing above purpose, technical solution of the present invention is: a kind of furan resin self curing sand, comprise roughing sand, binding agent, curing agent and lubricant, wherein, the consumption of curing agent is the 40-60% of binding agent consumption, the consumption of binding agent is the 3-5% of roughing sand consumption, and the consumption of lubricant is the 2-4% of roughing sand consumption, and curing agent is a kind of peracid and low sour mixture.
The consumption of described curing agent is 50% of a binding agent consumption, and the consumption of binding agent is 4% of a roughing sand consumption, and the consumption of lubricant is 3% of a roughing sand consumption, and curing agent is a kind of peracid and low sour mixture.
The constituent of described curing agent and weight portion ratio thereof are: peracid 40-60, low sour 60-40.
The constituent of described peracid and weight portion ratio thereof are: sulfuric acid 40-60, and phosphoric acid 30-40, all the other are water.
The constituent of described low acid and weight portion ratio thereof are: sulfuric acid 10-20, and phosphoric acid 20-30, all the other are water.
Compared with prior art, beneficial effect of the present invention is:
1, because a kind of furan resin self curing sand of the present invention comprises roughing sand, binding agent, curing agent and lubricant, wherein, the consumption of curing agent is the 40-60% of binding agent consumption, the consumption of binding agent is the 3-5% of roughing sand consumption, the consumption of lubricant is the 2-4% of roughing sand consumption, and curing agent is a kind of peracid and low sour mixture, because the curing agent that uses in this design is a kind of peracid and low sour mixture, can effectively reduce the sulfur content in the self-hardening sand, improve the toughness of the core of self-hardening sand manufacturing.Therefore sulfur content of the present invention is lower, toughness is bigger.
2, constituent and the weight portion ratio thereof owing to curing agent in a kind of furan resin self curing sand of the present invention is: peracid 40-60, low sour 60-40, the constituent and the weight portion ratio thereof of preferred peracid are: sulfuric acid 40-60, phosphoric acid 30-40, all the other are water, the constituent and the weight portion ratio thereof of low acid are: sulfuric acid 10-20, and phosphoric acid 20-30, all the other are water, this kind design not only can improve strength and toughness of the present invention, and raw material are easy to get, and are cheap, help reducing production costs.Therefore not only intensity is big, toughness is better in the present invention, and production cost is lower.
