Abstract
The invention discloses a kind of environment-friendly type composite dry material bonding agent and its application method, described environment-friendly type composite dry material bonding agent includes the raw material of following percentage by weight：Powdered phenol-formaldehyde resin 40%, glucose 60%.The environment-friendly type composite dry material bonding agent of the present invention is due to the reasonable addition of glucose; the addition of phenolic resin is reduced from ratio; reduce the discharge of the compositions such as formaldehyde in baking process, cresols, xylenol; reduce the residual carbon content after solidification; both protect environment, reduce the discharge of pollutant; the remaining carbon after solidification is reduced again and has reached the purpose for improving Cleanliness of Molten Steel, simultaneously because the price of glucose is only the 1/3 of powdered phenol-formaldehyde resin, effective reduction is realized from cost.
Description
Technical field
The invention belongs to dry materials bonding agent technical field, and in particular to a kind of environment-friendly type composite dry material bonding agent and its
Application method.
Background technology
As China's continuous casting even pours horizontal continuous improvement, the working life of continuous casting production working lining is significantly prolonged
It is long, from original 5 hours develop into today more than 40 hours.Tundish dry material is after tundish insulating board, tundish
The new unshape refractory of bakie working lining after coating (spray paint), when its maximum feature is to construct not
Water, and construction is simple need to be added, service life length, high insulating effect, bag is easily turned over after.Currently used dry materials bonding agent
For phenolic resin, but during dry materials baking-curing, powdered phenol-formaldehyde resin decomposites part formaldehyde, cresols, xylenol etc.
Composition has a certain degree of pollution to environment so as to discharge excitant taste, meanwhile, the carbon residue after solidification easily causes to molten steel
Pollution, there is carburetting than relatively low steel grade to smelting carbon content, less adapt to the smelting of mild steel.
It is therefore desirable to develop a kind of environment-friendly type composite dry material bonding agent effectively to solve the above problems.
The content of the invention
It is an object of the invention to provide a kind of environment-friendly type composite dry material bonding agent and its application method.
Environment-friendly type composite dry material bonding agent of the present invention, include the raw material of following percentage by weight：Powdered phenolic
Resin 30~50%, glucose 50~70%.
Preferably, described composite dry material bonding agent includes the raw material of following percentage by weight：Powdered phenol-formaldehyde resin 35
~45%, glucose 55~65%.
It is further preferred that described composite dry material bonding agent includes the raw material of following percentage by weight：Powdered phenolic
Resin 40%, glucose 60%.
Preferably, the granularity of described powdered phenol-formaldehyde resin is 180~200 mesh.
Preferably, the granularity of described glucose is 180~200 mesh.
A kind of application method of environment-friendly type composite dry material bonding agent, described application method are first by the Portugal of formula rate
Grape sugar is well mixed with powdered phenol-formaldehyde resin, is then added according to 4~6% addition of dry materials weight into dry materials again
Secondary to be sufficiently mixed uniformly, being subsequently poured into mould can be stripped after vibration baking solidification.
Preferably, described addition is the 5% of dry materials weight.
Preferably, the temperature of described baking-curing is 180~220 DEG C.
Beneficial effects of the present invention：
1st, environment-friendly type composite dry material bonding agent of the invention reduces phenolic aldehyde tree due to the reasonable addition of glucose from ratio
The addition of fat, reduce the discharge of the compositions such as formaldehyde in baking process, cresols, xylenol, reduce the carbon residue after solidification and contain
Amount, environment both protected, reduced the discharge of pollutant, and reduced the remaining carbon after solidification again and reached raising Cleanliness of Molten Steel
Purpose, simultaneously because the price of glucose is only the 1/3 of powdered phenol-formaldehyde resin, effective reduction is realized from cost.
2nd, the environment-friendly type composite dry material bonding agent involved by patent of the present invention is mixed using glucose and powdered phenol-formaldehyde resin
Close, added after well mixed by appropriate addition into dry materials and with dry materials be sufficiently mixed uniformly.During construction simultaneously
It is not required to add water, dry materials are poured into mould can be stripped after vibration baking solidification, and low-temperature fast-curing, convenience is realized in baking
The demoulding.
