Synthetic example 3

[0031]Add 100 parts by mass of water glass and 100 parts by mass of water in a four-necked flask, add 80 ml of hydrochloric acid under rapid stirring, then add 6 parts by mass of dimethylvinylethoxysilane, 6 parts by mass Parts by mass of hexamethyldisiloxane and 90 parts by mass of ethanol were stirred and reacted at 50-60° C. for 30 minutes, and then 100 parts by mass of hexamethyldisiloxane was added and stirred for 1 hour. Stand to separate layers, remove the lower layer of dilute hydrochloric acid ethanol solution. Add 15 parts of concentrated hydrochloric acid to the resin solution in the upper layer under stirring, and stir and react at room temperature for 2 h. Then stand to separate the sulfuric acid, wash with water until neutral, and after drying with calcium chloride, distill the hexamethyldisiloxane to obtain a vinyl MQ silicone resin with an M / Q of 0.7 and a vinyl mass fraction of 3.5%.

Abstract

The invention discloses a preparation method of silicane functionalized graphene, antistatic organic silicon pressure sensitive adhesive and a preparation method thereof. The technical problems are solved that existing graphene is unevenly dispersed in the organic silicon pressure sensitive adhesive and the surface of the organic silicon pressure sensitive adhesive after coating and forming has high static electricity so that hidden safety dangers can be brought to coating and production, the graphene oxide after silane is modified is used for giving antistatic performance to the pressure sensitive adhesive under the condition that the curing performance, coating technology and weather-proof performance of the pressure sensitive adhesive cannot be influenced, and the adverse effect causedby static electricity can be eliminated in the coating technology and the using process of formed products.

Description

technical field [0001] The invention relates to the technical field of graphene, in particular to a preparation method of silanized graphene, an antistatic silicone pressure-sensitive adhesive and a preparation method thereof. Background technique [0002] Graphene is a new type of nanomaterial with excellent electrical, thermal and mechanical properties. It has great market potential as an additive for silicone pressure-sensitive adhesives. However, graphene is easy to agglomerate and has poor compatibility with silicone pressure-sensitive adhesives. , which makes it difficult to disperse evenly in the silica gel hypoallergenic adhesive, so that the excellent characteristics of graphene itself cannot be exerted. Therefore, surface modification of graphene to achieve good dispersion in silicone pressure-sensitive adhesives is the prerequisite for the preparation of high-performance silicone pressure-sensitive adhesives. [0003] At present, patents using modified graphene i...
