Description
Technical field
The present invention relates to a kind of face layer anti-cracking agents and preparation method thereof.
Background technology
Face layer anti-cracking agent is the compatibility chemicals for adding the normal temperature strength in investment precoat for improving shell, is belonged to
Environmentally friendly formulation product is mainly used for process for making shell in precision-investment casting industry.By the external factor such as humidity and material
Expect the factors such as the coefficient of expansion, the casting of precision-investment casting is usually cracking, scaling and the problems such as surface cracking.Temperature compared with
When low, the humidity in air is relatively low, is deep hole part, the larger workpiece of specific surface area or larger heavier casting for precision castings,
In the drying process of process for making shell, because drying time is long, shell is susceptible to cracking.In the north, humid control is bad to be caused
Shell cracking degree can reach 60%-70%.Precision-investment casting investment precoat main component is zircon sand powder, white alundum powder, palm fibre
Schmigel, silica flour, mullite powder etc., are mainly derived from ore, wherein containing certain impurity, because of the place of production of ore, processing work
Skill is different, and impurity content difference is larger, and different material coefficient of expansion when heated is different, to make shell in steam dewaxing
Face layer is cracked, so as to cause surface quality of continuous castings problem.
Currently, the face layer anti-cracking agent effect type of commercial type is seldom, it is such as poly- substantially to add single polymer
Ethylene glycol etc. increases the normal temperature strength of shell.Polymer belongs to polymer substance, and dissolving is more difficult, and has certain viscosity,
It is added in investment precoat, leads to the poor fluidity of investment precoat, influence mucilage；Meanwhile because investment precoat viscosity becomes larger, stablize
Property be deteriorated, coating it is apt to deteriorate.Therefore it is smaller in actual production process application.In addition, shell goes out in drying process in order to prevent
Existing cracking, water or installation humidifier often spread on the ground in precision-investment casting factory, with the humidity for keeping drying plant certain.This
Method has certain effect to surface cracking, but drying time is longer, and production efficiency reduces, and electricity consumption is big, causes to produce
Cost increases.
