Abstract
The invention discloses a method for manufacturing an aluminum oxide substrate polishing material for an automobile painting surface. The method is characterized by comprising the following steps: a) calcining pseudoboehmite which contains less than or equal to 0.5% of impurities, such as Na ion and the like, and then keeping temperature, thereby obtaining aluminum oxide powder, and b) twice screening the obtained aluminum oxide powder, thereby obtaining fine aluminum oxide powder, wherein in the step a), the calcining temperature of the pseudoboehmite is 800-1200 DEG C, the time of keeping temperature is 2-5 hours, and the specific surface area of the obtained aluminum oxide powder is 1g/m<2>-40g/m<2>, and in the step b), the particle size of the fine aluminum oxide powder is 1-40 microns. The method for manufacturing the aluminum oxide substrate polishing material for the automobile painting surface provided by the invention has the advantages that the fine aluminum oxide powder polishing material prepared according to the method is small in granularity, is high in safety and meets the high polishing demands of products.
Description
Technical field
The present invention relates to a kind of automobile finish polishing raw material, especially relate to a kind of automobile finish polishing raw material making method of alumina host.
Background technology
Automobile all can carry out polished finish to lacquer painting when daily maintenance and maintenance, to reach certain smooth finish.So-called polishing is exactly to remove to grind the vestige of leaving over, and all contain certain friction materials in these polishing articles for use, and the friction materials particle size is different, and purposes is also different; The quality of quality of finish is very big to car lacquer appearance and the influence of corrosion resistant ability, even can influence the value of automobile itself, therefore, in polishing process to the requirement of polishing raw material also than higher.
Summary of the invention
It is fine and smooth that technical problem to be solved by this invention provides a kind of granularity, the automobile finish polishing raw material making method of safe a kind of alumina host.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions.
The automobile finish polishing raw material making method of this alumina host is characterized in that, may further comprise the steps:
A, foreign matter contents such as Na ion are less than or equal to 0.5% pseudo-boehmite calcine, insulation obtains alumina powder then;
B, prepared alumina powder is carried out twice screening, obtain aluminum oxide fine powder.
In order under specified temp and time, to make product, further, the calcining temperature of pseudo-boehmite is 800-1200 ℃ among the said step a, and soaking time is 2-5 hour, and prepared alumina powder surface ratio is 1g/m
2-40 g/m
2
In order to guarantee the exquisiteness property of aluminum oxide fine powder, more further, the aluminum oxide fine powder granularity is 1-40um among the said step b.
Compared with prior art, usefulness of the present invention is: the prepared aluminum oxide fine powder polishing of the making method raw material granularity of the automobile finish polishing raw material of this alumina host is thin, safe, can satisfy the demanding product of polishing.
Embodiment:
Describe the present invention through embodiment below:
A kind of automobile finish polishing raw material making method of alumina host is characterized in that, may further comprise the steps:
A, foreign matter contents such as Na ion are less than or equal to 0.5% pseudo-boehmite calcine, insulation obtains alumina powder then;
B, prepared alumina powder is carried out twice screening, obtain aluminum oxide fine powder.
The calcining temperature of pseudo-boehmite is 800-1200 ℃ among the said step a, and the too high meeting of temperature causes product hardness too high, can cause bigger scuffing to the polished object surface, and temperature is crossed to hang down and can be caused the hardness of product not enough, can't reach desirable polishing effect; In order to access alumina powder, burnt pseudo-boehmite need be incubated 2-5 hour, and then to obtain specific surface be 1g/m
2-40 g/m
2Alumina powder; Prepared alumina powder need pass through the postsearch screening classification, obtains the fine powder that granularity is 1-40um then.After handling through prescription, this raw material can be used for the polished finish of aspects such as automobile finish machinery.
It is emphasized that: above only is preferred embodiment of the present invention; Be not that the present invention is done any pro forma restriction; Every foundation technical spirit of the present invention all still belongs in the scope of technical scheme of the present invention any simple modification, equivalent variations and modification that above embodiment did.
