Abstract
A heating adhesive tape contains such components as LDPE, acetylene black, graphite, cross-linking agent "DCP", antioxidizing agent "1010", anti-ageing agent "DLTP", diffusant M-9, combustion inhibitor and protecting film, and features that copper wire net is used as electrode, which has been thermally treated. Its advantages are no change in contact resistance, uniform temp and high safety.
Description
The present invention relates to a kind of heat generating adhesive tape.
At present can see heat generating adhesive tape on the domestic and international market, but the electrode of its Chemical Composition and use is not quite similar, the composition of external product comprises: LDPE (low-density high-pressure polyethylene), carbon black, graphite, Copper Foil, card-protecting film (PET+LDPE); The composition of home products comprises: LDPE (100 parts), carbon black (20-50 part), graphite (10-30 part), DCP linking agent (2-6 part), antioxidant 1010 (0-5 part), antioxidant D LTP (0-5 part), card-protecting film (PET+LDPE) are two-layer up and down.With LDPE is matrix, adds electro-conductive material carbon black and graphite, but mixes inhomogeneously, causes the heating element one section awfully hot, and a certain section not hot, non-uniform temperature.The electrode materials that adopts is a Copper Foil, and Copper Foil and black matrix do not stick together, and surface contacted resistance is increased, and after use for some time, Copper Foil and black matrix leave, because of contact resistance is big, and local superheating, presence of fire easily, once Copper Foil has broken, consequence is even more serious.
The object of the present invention is to provide a kind of contact resistance can not become greatly, everywhere the uniform heat generating adhesive tape of temperature.
The present invention is achieved in that product composition of the present invention comprises: LDPE gets 100 parts, and acetylene black is got 20-70 part, and graphite is got 20-70 part, crosslink agent DCP is got 0.1-2 part, antioxidant 1010 is got 0.1-0.5 part, and antioxidant D LTP gets 0.1-0.5 part, and dispersing agent M-9 is got 2-5 part, fire retardant has three kinds: clorafin is got 15-30 part, stibium trioxide is got 15-20 part, and tetramethylolmethane is got 0.2-2 part, and electrode adopts copper mesh and copper wire, get two or many, card-protecting film is got two-layer up and down.
The present invention adopts copper mesh and copper wire to make electrode, and it can be deep in the black matrix, how to use also and does not separate, and has solved the big problem of contact electricity resistive; Add strong matrix LDPE of dispersing agent M-9 and conducting material carbon black, graphite etc. in the composition and mix equably, make resistance value everywhere identical, promptly each position temperature is even; Add fire retardant,, also can not blaze up even electrode has broken, safe and reliable.
Describe the present invention below in detail:
The present invention includes following composition:
100 parts of LDPE (low-density high-pressure polyethylene)
Acetylene black 20-70 part
Graphite 20-70 part
Crosslink agent DCP (dicumyl peroxide) 0.1-2 part
Antioxidant 1010 (tetramethylolmethane) 0.1-0.5 part
Antioxidant D LTP (sulfuration dipropionic acid two bays) 0.1-0.5 part
Dispersing agent M-9 (ultrafiltration xylogen sodium sulfonate) 2-5 part
Fire retardant:
Clorafin 15-30 part
Stibium trioxide (antimonous oxide) 15-20 part
Tetramethylolmethane 0.2-2 part
Card-protecting film (PET+LDPE) is two-layer up and down
Electrode: two or many on copper mesh and copper wire
Production technique is as follows:
Batch mixing: in mixing machine, carry out;
Granulation: carry out in the SJ-65 machine, the membrana oralis temperature is 200 ℃, and the electric motor revolution is 600-1200 rev/min;
Pelletizing: in dicing machine, carry out;
Compressing tablet: carry out in the YY-65 machine, the membrana oralis temperature is 200 ℃, and the temperature of stack is 60 ℃ of 80 ℃ of lower rolls of top roll;
Compound: carry out in the FH-240 machine, the up-down rollers temperature is 135-150 ℃, and the temperature of rubber roll is 60 ℃, and the humidity of compound chamber is not more than 50%, and room temperature is 20 ℃, and recombination velocity is the 1-3M/ branch;
Thermal treatment: carry out in heat treatment box, treatment temp is 90 ℃, and the treatment time is 9-15 hour.
