Description
Technical field
The present invention relates to a kind of manufacture method of the runner plate that insulate, be specifically related to the manufacture method of insulation of a kind of high life based on plasma spraying runner plate.
Background technology
When the main body base material on manufacturing line road plate (PCB), need to use electric press that materials different for multilayer is carried out pressing, the principle of work of this electric press is by the processed tacky resin material of Copper Foil (or aluminium foil) conduction heating, and by applying certain pressure, multilayer material is pressure bonded to not a half hour, thus obtained board substrate, and in use electric press bonding processes, for cost consideration, single stitching operation often needs the multi-disc of pressing simultaneously board substrate, and in order to make multi-disc board substrate when pressing, be not affected each other, need them superimposed, and insert a kind of special insulcrete between which, it has insulation, heat transfer, the effect supporting and be separated, this special insulcrete with superelevation planeness is called runner plate.
Runner plate and the maximum difference of common insulcrete are exactly the coating that there is a kind of densification on its surface, the performance of this coating on runner plate has great impact, in process for pressing, very high to the performance requriements of runner plate, electric press is when operating, both heat of high temperature (being greater than 300 DEG C) had been produced, there is again very strong pressure (being greater than 50MPa), this just needs runner plate to possess outstanding resistance to hot press performance, namely runner plate needs to have very high limit tolerable temperature and limit tolerance pressure, and, more weight is, the top coat of runner plate still must can keep flat smooth very after repeatedly hot pressing, surface is depression not, there is not breathing, and in existing technique, also cannot realize this requirement at present, after the runner plate of prior art generally about can use about 100 times at normal temperatures, its surface just starts to occur depression, runner plate is caused to lose efficacy, and at high temperature also only can use and just lost efficacy for about 50 times.And in the major cause that prior art cannot meet this requirement be preparation technology's also prematurity of this coating, more particularly, be coating formula and coating construction technology also perfect connected applications.
Summary of the invention
For the deficiencies in the prior art part, the object of the present invention is to provide the manufacture method of insulation of a kind of high life based on plasma spraying runner plate, the runner plate produced by this manufacture method can realize the use ensureing high frequency time when the hot pressing of High Temperature High Pressure power, not breathing, surfacing is wear-resisting, does not cave in.
Plasma spray coating process belongs to prior art, it adopts the plasma arc of direct-current drive to make thermal source, by heating materials such as pottery, alloy, metals to melting or semi-melting state, and drive the powder spray of melting to workpiece surface to be sprayed with rare gas element high pressure spraying thus form the upper layer of adhere firmly.
Technical scheme of the present invention is summarized as follows:
Based on a manufacture method for the high life insulation runner plate of plasma spraying, comprise the following steps:
1) by substrate to be sprayed through pickling, degreasing post-drying;
2) substrate is carried out corona treatment;
3) coat powder is sprayed into substrate surface through plasma spraying method;
Wherein, described coat powder comprises the material of following weight part:
Titanium oxide 100 weight part;
Barium oxide 30 ~ 32 weight part;
Boron oxide 10 ~ 12 weight part.
Preferably, the manufacture method of the described insulation of the high life based on plasma spraying runner plate, wherein, described substrate is aluminium sheet or stainless steel plate.
Preferably, the manufacture method of the described insulation of the high life based on plasma spraying runner plate, wherein, described coat powder also comprises the lanthanum trioxide of 6 ~ 8 weight parts.
Preferably, the manufacture method of the described insulation of the high life based on plasma spraying runner plate, wherein, described coat powder also comprises the nickel oxide of 3 ~ 5 weight parts.
Preferably, the manufacture method of the described insulation of the high life based on plasma spraying runner plate, wherein, described coat powder also comprises the magnesium oxide of 3 ~ 5 weight parts.
The invention has the beneficial effects as follows: this case is the formula of coat powder according to plasma spray coating process brand-new design, this formula can be applicable to plasma spray coating process well, the sprayed coating of one deck densification is formed at substrate surface, this coating can make insulation runner plate can realize being ensured the use of high frequency time during hot pressing in High Temperature High Pressure power, not breathing, surfacing is wear-resisting, does not cave in.
Embodiment
Below in conjunction with embodiment, the present invention is described in further detail, can implement according to this with reference to specification sheets word to make those skilled in the art.
This case proposes the manufacture method of the insulation of the high life based on the plasma spraying runner plate of an embodiment, comprises the following steps:
1) by substrate to be sprayed through pickling, degreasing post-drying;
2) substrate is carried out corona treatment;
3) coat powder is sprayed into substrate surface through plasma spraying method;
Wherein, coat powder comprises the material of following weight part:
Titanium oxide 100 weight part;
Barium oxide 30 ~ 32 weight part;
