Problems solved by technology

[0004] Most of the adhesives currently available in the market do not have the ability to resist high temperature, conduct electricity, and conduct heat, and are chemically unstable and cannot resist thermal shock. In such an environment, ordinary adhesives show their disadvantages, and cannot achieve the desired bonding effect, resulting in bonding failure and serious impact.

Embodiment 1

[0010] The technical solution adopted in this specific embodiment is: a graphite adhesive is composed of the following raw materials in parts by weight: 70 parts of graphite powder, 80 parts of neoprene rubber, 50 parts of acid anhydrides, 40 parts of stannous chloride, polysulfide 30 parts of rubber, 35 parts of triphenyl phosphate, 20 parts of toluene, and 5 parts of auxiliary materials. Its preparation process includes the following steps: 1. Melting neoprene rubber in a high-temperature melting furnace to transform it into liquid neoprene rubber. The temperature of the high-temperature melting furnace is 300-380° C. for 30-40 minutes; 2. Put an acid anhydride in the high-temperature melting furnace to solidify, so that the liquid neoprene rubber can be transferred into a chemical substance that does not melt and a strong adhesive layer. The temperature of the high-temperature melting furnace is reduced to 70-100°C for 20-25 minutes. Add stannous chloride at the same time a...

Embodiment 2

[0016] The difference between this embodiment and Example 1 is that it is made up of the raw materials of following parts by weight; 40 parts of triphenyl phosphate, 25 parts of toluene, 7 parts of auxiliary materials.

[0017] The composition of other raw materials and the preparation process are all the same as in Example 1.

Embodiment 3

[0019] The difference between this embodiment and Example 1 is that it is made up of the raw materials of following parts by weight; 45 parts of triphenyl phosphate, 35 parts of toluene, and 9 parts of auxiliary materials.

[0020] The composition of other raw materials and the preparation process are all the same as in Example 1.

[0021] After adopting the above technical solution, the beneficial effects of the present invention are: high temperature resistance, electric conduction, heat conduction ability, and chemical stability, thermal shock resistance, for some high temperature and need electric conduction, heat conduction and chemical stability, thermal shock resistance Under the environment of environment, graphite adhesive will show its advantages, achieve the desired bonding effect, make the bonding efficiency efficient and have corresponding special functions, and have a major impact.

Abstract

The invention provides a graphite binder and a preparation process thereof, and relates to the technical fields of binders and preparation of the binders. The graphite binder is composed of the following raw materials: graphite powder, chloroprene rubber, acid anhydrides, stannous chloride, polysulfide rubber, triphenyl phosphate, toluene, and an auxiliary agent; and the graphite binder can be prepared by taking the above raw materials according to a metering ratio and performing preparation according to the preparation process of the graphite binder. After the above technical scheme is adopted, the graphite binder provided by the invention has the beneficial effects of having high-temperature-resistant, electrical conductive and thermal conductive capability, chemical stability and thermal shock resistance; and in the environments needing high temperature, electrical conductivity, thermal conductivity, chemical stability and thermal shock resistance, the graphite binder shows the advantages, achieves a required bonding effect, realizes high bonding efficiency, and has corresponding special functions.

Description

technical field [0001] The invention relates to the technical field of adhesives and their preparation, in particular to a graphite adhesive and its preparation process. Background technique [0002] Graphite is an allotrope of elemental carbon. As early as the 1930s, graphite production and processing began in Jixi Liumao, Heilongjiang, China, and Nanshu, Shandong, graphite mines. Graphite and carbon products have excellent performance and are widely used, and the production capacity and benefits are showing a rapid growth trend. Judging from the development trend and competition pattern of the world's graphite and carbon products market, my country's graphite and carbon products industry will gradually concentrate in large groups in the future, and the concentration of graphite and carbon products industry will further increase. With the rapid development of China's metallurgy, chemical industry, machinery, medical equipment, nuclear energy, automobile, aerospace and othe...
