Embodiment Construction

[0027] Pipe preparation

[0028] (1) Put each raw material into a high-speed mixer according to the proportion shown in Table 1, knead until the temperature reaches 105°C and discharge, put it into a low-speed cooling mixer and cool to normal temperature to obtain a mixed powder;

[0029] (2) Put the mixed powder into the hopper of the extruder, the hopper is equipped with a forced feeding device to prevent the powder from bridging, and the hopper seat strengthens the water cooling device to prevent the powder from being heated and stuck;

[0030] (3) The extruded pipe adopts Φ90 extruder, the length-to-diameter ratio of the screw is 1:28, the screw type is BM type (separate type), and the temperature control is (five-zone heating of the fuselage): 140°C for the first zone and 150°C for the second zone , 155℃ in the third zone, 160℃ in the fourth zone, 165℃ in the fifth zone, 150℃ in the flange, and 168℃ in the machine head; the powder is extruded through the machine head;

Abstract

The invention discloses a polyvinyl chloride (PVC) hose pipe which is prepared from the following raw materials in parts by weight: 100 parts of PVC resin, 40-60 parts of plasticizer, 0.5-2 parts of diphenyl-isooctyl nitrite, 3-5 parts of hexametapol, 0.5-5 parts of thermal stabilizer and 0.1-1 part of lubricating agent. The special antioxidant and ultraviolet absorber are not added into the PVC hose pipe, so that the manufacturing cost is reduced; in addition, hexametapol is added into the PVC hose pipe, so that all components of the raw materials can be fully dissolved, and the whole performance of a tubular product can be improved; and furthermore, hexametapol can be used for complexing ferric ions and hydrogen chloride, so that the anti-aging performance of the hose pipe can be effectively improved.

Description

technical field [0001] The invention relates to a plastic pipe, in particular to a PVC hose. Background technique [0002] The main component of PVC is polyvinyl chloride, which is light yellow, translucent and shiny. Transparency is better than polyethylene and polypropylene, and worse than polystyrene. Depending on the amount of additives, it can be divided into soft and hard PVC. Soft products are soft and tough, and feel sticky. The hardness of hard products is higher than that of low-density polyethylene. And lower than polypropylene, there will be whitening at the inflection. [0003] PVC hose is cheap and good, and is currently recognized as a better outdoor water pipe, but the existing PVC hose also has shortcomings: PVC hose is exposed to wind and sun for a long time outdoors, which is easy to cause aging, and the polymer material Aging is mainly a chain reaction caused by free radicals attacking polymer chains. Generally, it is solved by adding antioxidants and ...
