Abstract
Flash preventing paste comprises fiber paper, high-temperature resistant glue and boron nitride coating. The fiber paper is mullite polycrystalline fiber paper (1) with the thickness of less than one millimeter. The inorganic high temperature resistant glue (2) is arranged on the mullite polycrystalline fiber paper (1). The boron nitride coating used for casting is arranged on the mullite polycrystalline fiber paper (1) and the inorganic high temperature resistant glue (2). The flash preventing paste has the advantages that the inorganic high temperature resistant glue is used as an adhesion metal die to fill up padding of damaged cavity joint corner angles, polycrystalline fiber paper is used as an insulating layer of high temperature resistant glue padding and the metal die to meet the requirements of instant hot repair, and the boron nitride coating is used as enhancers and release agents of the polycrystalline fiber paper so as to achieve the purposes of reinforcing the strength of the polycrystalline fiber paper, prolonging the service life of the flash preventing paste, and enabling a product to be free of flash.
Description
Technical field
The present invention relates to aluminium alloy casting field, specifically a kind of anti-overlap emplastrum.
Background technology
With the die cast alloy product time, need to carry out the sandblast spray paint to mould, but sandblast will damage the corner angle of die cavity joint close face, make product produce overlap, as repaired with cold welding, engineering duration not only, higher to specification requirement, also can affect production, therefore can only increase the workman carries out artificial deflashing, develop, increase manipulator deflashing equipment, wasted a large amount of manpowers and financial resources.
Summary of the invention
For above problem, the invention provides a kind of anti-overlap emplastrum, meet the demand of now producing instant hot repair, save production cost.
According to this programme, a kind of anti-overlap emplastrum, comprise fibrous paper, high-temperature plastic, boron nitride coating.
Described fibrous paper is the mullite polycrystalline fibre paper 1 that thickness is less than a millimeter.
Be provided with inorganic high-temperature resistant glue 2 on described polycrystalline fibre paper 1.
Be provided with the casting boron nitride coating on described polycrystalline fibre paper 1 and inorganic high-temperature resistant glue 2.
Technique effect of the present invention is: adopt inorganic high-temperature resistant glue to fill up the filler that damages die cavity joint close corner angle as the bonding metal mould, adopt the separation layer of polycrystalline fibre paper as high-temperature plastic filler and metal pattern, meet the requirement of instant hot repair; Adopt hardening agent and the releasing agent of boron nitride coating as polycrystalline fibre paper, meet strengthening polycrystalline fibre paper intensity, extend the service life of anti-overlap emplastrum, reach the purpose of product non-trimming.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the schematic diagram that the present invention repairs for metal die.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment in of the present invention is further described.
In Fig. 1, Fig. 2, comprise metal pattern 0, polycrystalline fibre paper 1, inorganic high-temperature resistant glue 2, damage die cavity joint close corner angle 3.
It shown in Fig. 1, is a kind of anti-overlap emplastrum.Comprise fibrous paper, high-temperature plastic, boron nitride coating.
Described fibrous paper is the mullite polycrystalline fibre paper 1 that thickness is less than a millimeter, is the basic unit of anti-overlap emplastrum.
Described high-temp glue is inorganic high-temperature resistant glue 2, is arranged on polycrystalline fibre paper 1.
Described boron nitride coating, brush on shaping rear defence overlap emplastrum, for the protection of anti-overlap emplastrum, is convenient to product stripping.
During use having damaged die cavity joint close corner angle 3 surperficial hackings in the counterdie of metal pattern 0, having cleaned to dustless, the mould temperature is when 60 spend, after pasting with the anti-overlap emplastrum of same area, depress patrix, be warming up to 80 degree insulation 1.5 hours, 150 degree insulation 1.5 hours, after solidifying, rise patrix, the equating inner cavity surface, brush boron nitride coating on the anti-overlap emplastrum after shaping, just can, for casting, cast out the product of non-trimming after dry.
Claims (2)
1. an anti-overlap emplastrum, is characterized in that: comprise fibrous paper, high-temperature plastic, boron nitride coating;
Described fibrous paper is the mullite polycrystalline fibre paper (1) that thickness is less than a millimeter;
Be provided with inorganic high-temperature resistant glue (2) on described polycrystalline fibre paper (1).
2. according to a kind of anti-overlap emplastrum claimed in claim 1, it is characterized in that: be provided with the casting boron nitride coating on described polycrystalline fibre paper (1) and inorganic high-temperature resistant glue (2).
