Abstract
The invention relates to sealing paraffin for an ultravioletdetector process. The sealing paraffin is prepared from the following raw materials in parts by weight: 4-8 parts of paraffin, 2-5 parts of Chinese insectwax, 2-5 parts of Brazilian palm wax, 2-5 parts of beeswax, 3-6 parts of stearic acid, 2-5 parts of polyethylene, 2-3 parts of rosin, 2-3 parts of sulfurpowder, 1-5 parts of calciumpowder and 2-4 parts of polyacrylic acid. Compared with the other paraffin, the sealing paraffin has the advantages that the hardness is extremely high and breaks through that of original paraffin, the sealing paraffin is wear-resistant, is good in closeness and can be used for balancing aluminum oxide on a substrate of a ultravioletdetector and preventing deformation. The hardness of the original paraffin is broken through, so that the sealing paraffin has a very high application value in the technical field of paraffin.
Description
technical field [0001] The invention relates to a kind of sealing paraffin for ultravioletdetector technology [0002] The invention relates to an industrial production technology. [0003] The invention relates to the technical field of paraffin wax. Background technique [0004] The substrate material of the ultraviolet detector is aluminum oxide. In the manufacturing process of ultraviolet detectors, a high-hardness sealing paraffin is required to cover the surface of the dielectric layer to balance the deformation stress of aluminum oxide. The hardness of ordinary paraffin cannot meet the needs of UV detector technology. The high-hardness waxes currently on the market mainly include carnauba wax, insectwax, polyethylene wax, Fischer-Tropsch wax, etc., but their hardness still cannot meet the requirements. The sealing paraffin wax used in the ultraviolet detector technology of the invention has extremely high hardness, wear resistance and good sealing performance. ...
