Abstract

The raw material of the inventive hose contains a soft material component and a hard material component. The soft material component contains (wt portion): Corvic 100, stabilizer 2-20, plasticizer 30-70, modifier 1-10 and lubricant 1-10 and the hard material component contains (wt portion): Corvic 100, stabilizer 2-15, modifier 2-10 and lubricant 1-10. After the soft and hard material components are heated, mixed and cooled separately in two high-speed mixers, they enter separately into two single-screw extruder and are then extruded the soft and hard materials separately. At last the spiral thread wound polyvinyl chloride hose is produced by the winding combination method.

Description

1. Technical field: [0001] The invention relates to a plastic hose and a production method thereof, in particular to a plastic-reinforced helically wound polyvinyl chloride hose and a production method thereof. 2. Background technology: [0002] Polyvinyl chloride (PVC) is used to manufacture various soft and hard pipes, and is widely used in industry, agriculture and the lives of the majority of residents. With the continuous development of the social economy, especially the continuous improvement of the living standards of the masses, people have higher and higher requirements for the quality standards of daily necessities. Spiral wound soft polyvinyl chloride, as a large class of polyvinyl chloride materials, has a large application field, and is widely used in the drainage of sanitary ware, and can also be used for drainage of air conditioners, washing machines, chemicals, buildings, etc. On the one hand, this type of PVC hose has become an indispensable product in the ...
