Abstract
The invention discloses a kind of moltening mold castings low molecule wax material reinforcing formulation, it is made up of according to weight fraction the following raw material：47 49 parts, No. 62 47 49 parts of paraffin of No. 58 paraffin, 35 parts of hardening agent, the present invention adds a certain proportion of No. 62 paraffin by major ingredient of No. 58 paraffin, lift wax material intensity, softening point, reduce wax material shrinkage, reduce shell processed and fall formwork cracking caused by part and wax material contraction, addition polyvinyl paraffin wax lifts wax material intensity as hardening agent, the low molecule wax material intensity of the formula is promoted to 4.5Mpa by 2.5Mpa before, one times of strength enhancing, shell processed falls part and is down to 3% by 8%, solves shell processed and falls part, formwork problem of Cracking.
Description
Technical field
The present invention relates to low molecule wax material reinforcement technique field, specially a kind of moltening mold castings low molecule wax material reinforcing is matched somebody with somebody
Side.
Background technology
Currently for automobile casting manufacturing enterprise, due to a series of spies such as the complexity of casting structure, thin wall type, lightweight
Point, model casting production takes advantage.Casting production process forms part model by mould by low molecule wax material and carries out shell processed
Cast forms part.The subject matter that shell surface processed is faced is that low ambient temperature/high temperature wax material is expanded big, and formwork ftractures, falls part, causes
Shell high expensive processed, wax material reinforcement technique exploitation is imperative.
The content of the invention
To achieve the above object, the present invention provides following technical scheme：A kind of moltening mold castings low molecule wax material reinforcing is matched somebody with somebody
Side, is made up of according to weight fraction the following raw material：
47-49 parts, No. 62 47-49 parts of paraffin of No. 58 paraffin, 3-5 parts of hardening agent.
It is preferred that, it is made up of according to weight fraction the following raw material：
47 parts, No. 62 47 parts of paraffin of No. 58 paraffin, 3 parts of hardening agent.
It is preferred that, it is made up of according to weight fraction the following raw material：
48 parts, No. 62 48 parts of paraffin of No. 58 paraffin, 4 parts of hardening agent.
It is preferred that, it is made up of according to weight fraction the following raw material：
49 parts, No. 62 49 parts of paraffin of No. 58 paraffin, 5 parts of hardening agent.
It is preferred that, the hardening agent uses polyvinyl paraffin wax.
Compared with prior art, the beneficial effects of the invention are as follows：The present invention adds certain proportion by major ingredient of No. 58 paraffin
No. 62 paraffin, lift wax material intensity, softening point reduces wax material shrinkage, reduce that shell processed falls part and wax material shrinks caused mould
Shell ftractures, and addition polyvinyl paraffin wax lifts wax material intensity as hardening agent, and the low molecule wax material intensity of the formula is by before
2.5Mpa is promoted to 4.5Mpa, one times of strength enhancing.Shell processed falls part and is down to 3% by 8%, solves shell processed and falls part, formwork problem of Cracking.
Embodiment
Below in conjunction with the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described,
Obviously, described embodiment is only a part of embodiment of the invention, rather than whole embodiments.Based in the present invention
Embodiment, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made, all
Belong to the scope of protection of the invention.
Embodiment 1：

The hardening agent uses polyvinyl paraffin wax.
The classification of paraffin：It is different according to processing and refining degree, fully refined paraffin wax, semi-refined paraffin wax and scale wax 3 can be divided into
Kind, fusing point is pressed again per class wax, typically every 2 DEG C, is divided into different kinds, such as 52,54,56,58,62 etc. the trades mark.Scale wax contains
Oil mass is higher, mainly for the manufacture of match, fiberboard, sail cloth etc..
The present invention adds a certain proportion of No. 62 paraffin by major ingredient of No. 58 paraffin, lifts wax material intensity, softening point, reduction
Wax material shrinkage, reduces shell processed and falls formwork cracking caused by part and wax material contraction, addition polyvinyl paraffin wax is carried as hardening agent
Wax material intensity is risen, the low molecule wax material intensity of the formula is promoted to 4.5Mpa, one times of strength enhancing by 2.5Mpa before.Shell processed
Fall part and be down to 3% by 8%, solve shell processed and fall part, formwork problem of Cracking.
It is obvious to a person skilled in the art that the invention is not restricted to the details of above-mentioned one exemplary embodiment, Er Qie
In the case of without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms.Therefore, no matter
