Embodiment 1

[0027] This embodiment relates to a kind of industrial binder, and its formula composition is shown in Table 1, and preparation method comprises the following steps:

[0028] Use rosin, industrial paraffin, and epoxy resin E51, weigh and configure according to the ratio of 3:2:0.1, put them all in an iron pot, heat for 30 minutes to 180°C to fully melt the three substances into a liquid state, at this time Stir evenly while heating. After stirring for 10 minutes, the three substances are fully dissolved. Take it down, place it in a cool place to cool for 45 minutes, put it in a paper cup, and cool it for 24 hours to become solid. When using, put the product and the bonding base (the product is Al 2 o 3 Ceramic material, base plate is Al 2 o 3 Ceramic materials) are placed on the heating plate at the same time, the temperature is set at 150°C, and heated for 20 minutes, because the adhesive will melt when heated, and then apply this adhesive evenly on the bonding base plate,...

Embodiment 2

[0031] This embodiment relates to a kind of industrial binder, and its formula composition is shown in Table 1, and preparation method comprises the following steps:

[0032] Use rosin, industrial paraffin, epoxy resin E51, weigh and configure according to the ratio of 2.5:1.5:0.1, put them all in an iron pot, heat for 30 minutes to 180°C to fully dissolve the three substances into a liquid state, at this time Stir evenly while heating. After stirring for 10 minutes, the three substances are fully dissolved. Take it down, place it in a cool place to cool for 45 minutes, put it in a paper cup, and cool it for 24 hours to become solid. When using, put the product and the bonding base (the product is Al 2 o 3 Ceramic material, base plate is Al 2 o 3 Ceramic materials) are placed on the heating plate at the same time, the temperature is set at 150°C, and heated for 20 minutes, because the adhesive will melt when heated, and then apply this adhesive evenly on the bonding base pl...

Abstract

The invention discloses an industrial binder for an aluminum oxide ceramic material. The adhesive is composed of rosin, industrial paraffin and epoxy resin. The mass ratio of the rosin to the industrial paraffin to the epoxy resin is (2.5-3): (1.5-2): 0.1. The industrial adhesive disclosed by the invention is convenient to bond and uniform to smear, so that a bonded product is good in flatness and can reach the processing precision; the operation is simple and convenient, no harm is caused to the body health of operators, and the working efficiency is greatly improved; the industrial binder is high in bonding strength, the bonding force can reach 80 + / -5 at 25 DEG C kgf / cm < 2 >, and the strength during processing can be achieved; the problem that products are loosened in the machining process can be solved, the qualified rate of the products is increased, scrapping is reduced, and the product quality is improved by 20%; and moreover, the degumming cost is low, the degumming method is safer than a traditional degumming method, the metal cleaning agent cannot damage a machined part during degumming, waste liquid treatment is simple, and the influence on the environment is low.

Description

technical field [0001] The invention belongs to the technical field of materials, relates to the bonding technology in the precision machining process, and in particular relates to an industrial bonding agent for alumina ceramic materials. Background technique [0002] High-purity alumina ceramic materials require a binder that is easy to bond and easy to degumming during bonding. At present, in the bonding process in the precision machining process, the original bonding method is to use 502 glue or AB glue for bonding. These two kinds of glue bonding have a disadvantage. The degumming of 502 glue is very troublesome (it is very brittle after curing. , not resistant to shock and vibration, and its reliability is not high), it needs to be soaked in acetone for a long time to degumming, and the residual glue on the surface of the product is difficult to clean, and large-area bonding cannot be removed even after soaking in acetone. AB glue is also difficult to degumming, clean...
