Description
Technical field
The present invention relates to modified master of drip irrigation zone special use and preparation method thereof.
Background technology
The water saving dropper technology that northwest arid area is extensively promoted the use of is the important measures that guarantee agriculture production and environmental greening, is the indispensable water-saving irrigation techniques such as plant cotton, corn, vegetables and greening and afforestation afforestation.At present, the drought and water shortage areas, ground such as northwest, Xinjiang are large-scale promotion application, significant for agricultural produce, deserted mountain and desert afforestation, improvement arid severe environment.
But drip irrigation zone is to use polyvinyl resin as raw material production, in the situation that the petroleum-based energy crisis increases the weight of day by day, the resin price that the oil of take is raw material is high, hits new peak repeatly, causes the drip irrigation zone raw materials cost significantly to rise.
In order to reduce the drip irrigation zone raw materials cost, adding calcium carbonate modified filling master batch in drip irrigation zone is important method, but, because common filling master batch is all to add resin and additive modification granulation production with 400 orders-1250 purpose calcium powder, can add in general plastics, but can not add in drip irrigation zone, this is because can the serious quality product that reduces drip irrigation zone, does not reach the quality technology standard of drip irrigation zone and can't use.
According to the technological standard of drip irrigation zone state-run assets standard GB/T19812.3-2008 " plastic water saving is irrigated equipment, internally-inlaid drip irrigation pipe belt ", product all will carry out hydrostatic performance, the test of anti-drawing property.And add common filling master batch, can't be up to state standards, not only its mechanical property degradation but also ageing resistance also significantly lower, and the season cracking that can accelerate drip irrigation pipe belt causes damage, northwest drought water-deficient area particularly, physical features is higher, uviolizing is strong, has more accelerated the ager process of drip irrigation pipe belt and damages in advance.More than reaching half a year for the life cycles of the farm crop such as cotton, corn, vegetables, and reach especially several years for the drip irrigation zone of greening and afforestation.Drip irrigation pipe belt will stand the erosion of scorching summer and freezing winter and wind and frost sleet, has more accelerated the process of its aged deterioration, therefore require drip irrigation pipe belt to have stronger ageing resistance.
So common filling master batch can not add in drip irrigation pipe belt, can have a strong impact on and reduce its quality product and work-ing life.
