Electric heating item is 5-10 group, and the length-width ratio of graphene Electric radiant Heating Film is (20-30): 1, preparation method are as follows: 1) prepare stone
Black alkene coating liquid: nano-graphene is added in Heveatex, is stirring evenly and then adding into dispersing agent 5040, is ground with colloid mill
Stand for standby use afterwards, wherein nano-graphene dosage is the 15%-30% of the graphene coating liquid weight；The dispersing agent
5040 dosages are the 1% of the graphene coating liquid weight；2) breath pattern method prepares reinforcing layer: coated side surface clean is done
Only it and dries, cellulose acetate is dissolved in the solution for being configured to 6-12g/L in carbon disulfide, by coated side edge fold 5mm
After be laid in ice face, solution is uniformly brushed coated side surface formed thickness be 0.5-1.5mm polymer solution film, control
Humidity processed is 70-100%, temperature is 26 DEG C -28 DEG C, forms the acetate fiber with through-hole structure after carbon disulfide volatilization
Film, as reinforcing layer；3) it sprays and vulcanizes: vulcanizing agent is added in graphene coating liquid obtained by step 1) and is stirred evenly,
Spray gun is packed into after deaeration, graphene coating liquid is rolled smooth go forward side by side on reinforcing layer, with 40-50 DEG C of hot-pressing roller by even application
Row presulfurization, roll-in 30-50MPa, roll-in time are 15-30min, then continue to vulcanize 4-6h in 70-90 DEG C of baking oven, are taken
Coated side edge is cut after out, graphene Electric radiant Heating Film is made；4) it forms: graphene Electric radiant Heating Film obtained by step 3) is cut into institute
Need shape.
The beneficial effects of the utility model are: add reinforcing layer in the utility model graphene Electric radiant Heating Film, make coated side and
It is completely embedded between coat, solves the problems, such as poor compatibility between coated side and coat, be not in after repeated deformation
The case where coat falls off or is broken, prolongs its service life, and the graphene of high specific weight can be added in coat, is solved
Graphene content it is low caused by poor dispersion, the non-uniform problem of spontaneous heating, and graphene Electric radiant Heating Film can a point third gear adjust, electric blanket
Comfort level it is higher, graphene Electric radiant Heating Film operating voltage is low, and heating efficiency is high, energy-saving safe.
