Description
Technical field
The invention belongs to foam preparation technical field, in particular to a kind of barrier antidetonation based on PET modified composite material
Foam tape.
Background technique
Buffering foam be using foam material be substrate by compound separated type material be prepared with damping, sound-absorbing, close
Envelope effect material, be widely used in electric equipment products, component of machine, all kinds of small household appliances, Cellphone Accessories, industrial instrument,
Computer and perimeter equipment, automobile parts, audio-visual equipment, toy, cosmetics, process gift, Medical Instruments, electric tool, office
The insulation of stationery, shelf display, home decoration, acrylic glass, ceramic etc., stickup, sealing, anti-skidding and buffering are shockproof.
In terms of electronic product bumper and absorbing shock, the especially damping of electronic display bottom needs high foamability, Gao Rou
Softness and the fabulous ultra-thin cushioning materials of resiliency eliminate the Newton's ring generated between touch module by segment difference.
Present, the main problems are as follows:
1, traditional PE, PU and melamine foam have good resiliency and sound absorption qualities, but due to processing technology
Limitation, high foamability cannot be obtained and ultra-thin buffering foam material layer, traditional processing technology can only obtain 1mm or more
Buffering foam material layer；
2, since industrial instantly is mainly cool, damp, and many application environments of foam also usually and are paid no attention to
Think, easily growth bacterium, so that foam is corroded, and there is no moisture-proof effects for the paper tube spread on the market, this makes foam
Application range it is reduced；
3, since foam is plastic products, dust easily in absorption air, and on the market common foam do not have it is dust-proof
The effect of；
4, since foam application range is wider, loss is also larger, and used foam is usually simply discarded, and not only causes environment
Problem, and make the utilization of resources insufficient, it results in waste of resources.
