Description
Technical field
The present invention relates to Foundry Production technical fields, and in particular to a kind of high-strength cast iron binder.
Background technique
Construction environment-friendly type society has become public common recognition, and the industry that environment is polluted in industrial production all suffers from technology
Reform, the binder that foundry enterprise generally uses both at home and abroad at present is organic resin binder, and binder used all contains organic
Compound, in operation, these substances will evaporate worker from resin sand, in coremaking and casting process, toxic,
Pernicious gas is largely discharged, and pollutes working space, endangers the health of worker.In addition, its high cost and its
The features such as limitation in terms of casting quality, seriously constrain the further development of organic resin binder.
Waterglass is the inorganic binder of quartz sand and soda ash synthesis, is one of the most abundant substance of resource on the earth,
It is the smallest casting binder of current environmental pollution.Waterglass is although inexpensive and intensity is high, but collapsibility is poor, and reuse is difficult,
Resistance to water soak is poor, influences production efficiency and casting quality, constrains it in the application of casting iron field.Performance of the binder to casting
It is always casting for this purpose, how to coordinate to solve the various aspects of performance such as intensity, cost and the craftsmanship of binder with great influence
Make manufacturer and technical staff's major issue of interest.
Summary of the invention
For above-mentioned technical problem, the present invention provides a kind of high-strength cast iron binder, mutual by composite modifier
Effect, it is synergistic, improve the normal temperature strength of waterglass, and improve to a certain extent binder anti-moisture absorption property and
Collapsibility.
To achieve the goals above, The technical solution adopted by the invention is as follows:
A kind of high-strength cast iron binder, is prepared by the raw material of following parts by weight: 35-40 parts of clay, waterglass
40-46 parts, 5-10 parts of talcum powder, 6-8 parts of aluminium triphosphate, 2-3 parts of glycerol, 0.3-0.6 parts of coupling agent.
Preferably, above-mentioned high-strength cast iron binder, is prepared by the raw material of following parts by weight: 36-38 parts of clay,
42-44 parts of waterglass, 7-9 parts of talcum powder, 6-7 parts of aluminium triphosphate, 2-2.5 parts of glycerol, 0.4-0.6 parts of coupling agent.
Preferably, above-mentioned high-strength cast iron binder, is prepared by the raw material of following parts by weight: 37 parts of clay, water
43 parts of glass, 8 parts of talcum powder, 6.5 parts of aluminium triphosphate, 2.5 parts of glycerol, 0.5 part of coupling agent.
Preferably, the partial size of the talcum powder is 200 mesh.
Preferably, the coupling agent is silane coupling agent.
Preferably, the silane coupling agent is N- (β-aminoethyl)-γ-aminopropyltriethoxy dimethoxysilane.
Beneficial effects of the present invention are shown:
Binder of the present invention is suitable for various weather conditions, its solidification effect of cool, damp weather becomes apparent from, and solidification is anti-
Should be mild, water lock is good, places for a long time not stratified, and intensity is higher than traditional binder, and adhesive property is significant；Nothing in production process
Waste water,waste gas and industrial residue generates, science and technology environmental protection.
The present invention passes through scientific selection, repetition test, it is determined that optimal formula, aluminium triphosphate and talcum powder, clay
It interacts Deng as composite modifier, it is synergistic, the normal temperature strength of waterglass both can be improved, it is low to improve used sodium silicate sand
Collapsibility under temperature, and have and assign waterglass hydrophobic characteristic while waterglass excellent compatibility, that is, improve water glass
The resistance to water soak of glass to make binder provided by the invention intensity with higher, and improves bonding to a certain extent
The anti-moisture absorption property of agent, collapsibility；The binder will not discharge toxic and harmful gas, and to environment and human body, all there is no danger
Evil, belongs to the binder of environmentally friendly class.
Aluminium triphosphate can form [PO with talcum powder, clay as modifying agent glass soluble easily in water4]、[SiO4] compound
Waterglass adhesion strength can be improved in glass volume grid, in addition, in aluminium triphosphate modified water glass melt cooling process, by
It is differed in destruction of the crystal to adhesive film of precipitation, the effect of isolating, and phosphate glass with the contractility of silicate glass
Greatly, cause adhesive film to crack, thus make glass (sand) high temperature collapsibility be improved significantly；Silane coupling agent can improve water glass
The interface interaction of glass and casting can also make the water-resistant capacity of sodium silicate binder increase to improve adhesion strength, make
It is not easily to fall off for chemical coupling effect can be generated while curing agent with casting face；Modifying agent aluminium triphosphate, talcum powder pottery
In soil, contain Mg2+、Al3+Equal cations, on the one hand, ionic radius is smaller, and chemical valence is relatively high, to neighbouring-O-H key
Strong influence is generated, to weaken-O-H key and H2O molecular action, so that resistance to water soak is improved, it is on the other hand, right
Mg2+For, it is added in binder as a reactive component, with phosphate reaction, polymerization MgHPO can be formed4·xH2O, it
It is a kind of space network, is non-water-soluble products, the cement of formation is influenced smaller by humidity, and hydrone is not easy to invade it
In.
