Abstract

The invention discloses a spirally wound PVC hose with an inner composite reinforcing layer for sanitary ware and a preparation method thereof. The raw material formula of the spirally wound PVC hose includes a hard material component, a soft material component and an inner composite layer material component. Mix the hard material component, soft material component and inner composite layer material component respectively, place them in a high-speed mixer for heating and mixing, then place them in a cooling mixer for cooling, and put them into three Heat and melt extrusion in a plastic extruder, respectively extrude the soft cladding layer material, hard core layer material and inner wall composite coating layer soft material, and the extruded materials of the three extruders are co-extruded into a composite mold , Extrude the material strip, and finally use the spiral winding compound method to produce the spiral wound PVC hose with the inner composite reinforcing layer for sanitary ware. The product of the invention has good heat resistance, wear resistance, flexibility, aging resistance, high strength, flatness and hygienic performance, and greatly improves the safety and hygienic performance of the hose product.

Description

1. Technical field: [0001] 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. 2. Background technology: [0002] Polyvinyl chloride resin (PVC) is used to manufacture a variety of soft and hard plastic pipes and accessories, which are widely used in the lives of residents such as industry, agriculture, chemical industry, urban construction, sanitary ware, massage bathing, leisure bathing, and beach bathing.
