Abstract

The invention discloses a spirally wound PVC hose with an inner composite enhancement layer and for sanitary ware, and a preparation method thereof. A raw material formula of the PVC hose comprises ahard material component, a soft material component and an inner composite layer material component. The preparation method comprises the following steps: respectively mixing the hard material component, the soft material component and the inner composite layer material component; after mixing, respectively heating and mixing the above three components in a high-speed mixer; then respectively putting the three components into a cooling mixer for cooling; after cooling and discharging, respectively putting the three components into three plastic extruders for heating, melting and extruding so asto respectively extrude a soft coating layer material, a hard core layer material and a soft inner-wall composite coating layer material; co-extruding the materials, which have been extruded by the three extruders, into a composite die, and extruding material strips; and finally producing the spirally wound PVC hose with the inner composite enhancement layer and for the sanitary ware by adoptinga spiral winding compounding method. The PVC hose of the invention has good heat resistance, abrasion resistance, flexibility and aging resistance and high strength, flatness and sanitation performance, and are greatly improved in safety and sanitation performance.

Description

[0001] 1. Technical field: [0002] The invention relates to a polyvinyl chloride hose for sanitary ware and a preparation method thereof, in particular to a helically wound PVC hose with an inner composite reinforcing layer for sanitary ware and a preparation method thereof. [0003] 2.
