Abstract

The invention discloses a wear-resistant and ageing-resistant PVC (polyvinyl chloride) reinforced hose pipe. The reinforced hose pipe comprises an inner pipe and an outer pipe, wherein the inner pipe and the outer pipe consist of the following raw materials in parts by weight: 100 parts of PVC, 2-3 parts of heat stabilizer, 25-30 parts of environment-friendly plasticizer, 5-8 parts of anti-freezing agent, 5-10 parts of anti-impact modifier, 2-3 parts of ultraviolet screening agent, 2-3 parts of pigment fillers, 4-6 parts of wear-resistant modifier and 1-3 parts of antioxidant. A preparation method of the reinforced hose pipe comprises the following steps of: 1) evenly mixing all the raw materials; 2) mixing-granulating; 3) extruding a PVC inner pipe body from a first extruder, cooling for shaping the inner pipe body, and drawing the inner pipe body; 4) winding the surface of the inner pipe body with polyester fibers, and then heating and drying the inner pipe body; and 5) extruding an outer pipe body from a second extruder, cooling for shaping the outer pipe body, and drawing the outer pipe body. The reinforced hose pipe prepared by the method has excellent mechanical performance and excellent antioxidant capability.

Description

technical field [0001] The invention relates to a wear-resistant and aging-resistant PVC reinforced hose and a preparation method thereof. Background technique [0002] The structure of PVC reinforced hose is generally: inner layer, fiber reinforced interlayer, and outer layer. The characteristics of this reinforced hose are: good pressure resistance, strong tensile strength, good corrosion resistance, small quality, and low price. The cost performance is generally better than that of pure PVC hoses, fire hoses, etc. It is widely used in fields such as farmland irrigation and the transportation of fluid media in the food industry. However, the research work on the formulation design of inner and outer pipes has not been satisfactory for a long time. , the performance in its mechanical properties or other aspects is not very good. Contents of the invention [0003] The object of the present invention is to provide a wear-resistant and aging-resistant PVC reinforced hose an...
