Description
Technical field
The utility model relates to drainpipe field, specially a kind of EVA drainpipe.
Background technique
Drainpipe mainly undertakes the task of the drainings such as rainwater, sewage, farmland discharging-irrigating.Drainpipe is divided into plastic drain-pipe, mixes
Solidifying soil pipe and concrete reinforced pipe etc..The main application of drainpipe has highway longitudinally, laterally to drain and permeable；Highway
The various shelves cob walls back side and gutter be vertical, horizontal drainage；The draining in tunnel, tube；Municipal works, water treatment plant, sewage plant, rubbish
The plumbing such as rubbish field；The draining of golf course, sports ground, the park greenery patches Deng Xiuxie；Hillside develops side slope water and soil conservation；It is whole
The subdrainage etc. of ground engineering.
EVA refers to ethylene-vinyl acetate copolymer.When the content of vinyl acetate in EVA is lower than 20%, at this moment
It can be used as plastics use.EVA (PA66) has good resistance to low temperature, and thermal decomposition temperature is lower, and about 230 DEG C or so, with
The increase of molecular weight, the softening point of EVA rise, processability and the decline of plastic lustrous surface, but intensity increases, impact flexibility
It is improved with environmental stress crack resistance, compared with PE in terms of the chemical-resistant resistance of EVA, oil resistivity, PVC is slightly worse, and with vinyl acetate
The increase of content changes more obvious.
The performance improvement of EVA ratio PE, mainly elasticity, flexibility, glossiness, gas permeability etc., in addition, its resistance to environment
Stress cracking resistance is improved, and to being increased by capacitive for filler, can be avoided using the method that more reinforcing filler is added
Or reduce the decline of EVA mechanical property ratio PE.There is preferable elasticity by drainpipe made of main material of EVA, and impact
