Description
Technical field
The present invention relates to field of mechanical technique, and in particular to sand casting technical field, more particularly to a kind of casting silicon
Hydrochlorate binding agent.
Background technology
Casting, is a kind of method that machinery manufacturing industry makes part blank, external mold (type) is first made of certain material and interior
Mould (core), external mold (type) and internal model (core) combination formed die cavity is identical with required target part shape, adjoining dimensions, then will select
The metal molten for determining material is poured into die cavity into liquid, treat molten metal cooled and solidified generate needed for product --- casting.According to
It is different according to the material for making die cavity, there are the casting techniques such as sand casting, model casting, permanent mold casting, lost foam casting, its
In, sand casting, because the cost of material is low and productivity ratio high, is a kind of main casting technique.In sand casting, casting is viscous
It is necessary to tie agent, and its effect is that sand grains is bonded into various required shapes --- sand mold or core.
Sand mold (core) can use that inorganic binder and organic binder bond are affected, and silicate binder is used as inorganic binder
One kind, from 1950s introduce casting industry (Czech doctor L.Petrzela in 1948 obtain BP
GB782205 since), rapid popularization has been obtained in China, moisture resistance is poor, collapsibility is poor however, this binding agent has, production
The low problem of efficiency, starts gradually to be substituted by organic binder bond, with furane resins, phenolic resin, polyurethane resin etc. the eighties
For the organic binder bond of representative, with the advantage such as production efficiency is high, combination property is good, it is widely used in sand casting within nearly 30 years
Industry.But using organic synthetic resin as the technique of binding agent, the meeting during mulling, moulding, coremaking, cast and sand removal etc.
Discharge various poisonous, pernicious gases (such as：Formaldehyde, phenol, furfuryl alcohol, benzene,toluene,xylene etc.), as main in Foundry Production
Want one of pollution sources.
The need for adapting to Green foundry and the strategy of sustainable development, inorganic binder have non-volatile VOC and it is poisonous,
The advantages of pernicious gas, the great attention of countries in the world founder author is caused again, particularly in efficient coremaking field, silicon
Hydrochlorate binding agent has obtained developing on a large scale very much.A kind of silicate binder is described in CN1106237, is heated using to mould, and
It is aided with the method quickening core solidification for blowing hot-air, a kind of practicable method is proposed to improving coremaking efficiency, however, passing through
The core moisture resistance that the technique makes is poor, and storage period is short, and core collapsibility is poor after cast, and cast cleaning is difficult, it is impossible in reality
Applied in production process.JPS52124414A discloses a kind of molding material, by silicate solutions and amorphous silicic acid powder group
Into, with normal silicate solution ratio, its core moisture resistance has certain raising, but under conditions of high humidity, complex thin-wall core
Still easily collapse, storage period is still too short.
The content of the invention
The technical problems to be solved by the invention be overcome prior art exist defect there is provided a kind of casting silicate
Binding agent.
In order to solve the above-mentioned technical problem, the present invention provides casting silicate binder, and it is by first component and second component
Constitute, first component is silicate solutions, second component is reinforcing agent, and the weight ratio of first component and second component is 10:2~7；It is described to increase
Strong agent is 30~90 by parts by weight：15~75 spodumene and sodium aluminate composition.Wherein, the weight ratio of first component and second component is excellent
Elect 10 as:4~5.
It is preferred that, the reinforcing agent is after mixing spodumene and sodium aluminate in proportion, at 350~950 DEG C, roasting 1~
Prepare within 5 hours.
It is preferred that, the spodumene amount containing lithium is 2~10%.
