Embodiment 1

[0039] S1. 100 parts of SG-3PVC resin, 40 parts of tributyl citrate, 8 parts of epoxy soybean oil, 16 parts of dioctyl terephthalate, 0.9 parts of Ca / Zn composite stabilizer, and 0.1 part of stearic acid , 4 parts of carbonamide, 1 part of sodium alkylbenzene sulfonate and 1 part of potassium sorbate were put into a high-speed mixer, kneaded until the temperature reached 105°C and discharged, put into a low-speed cooling mixer and cooled to normal temperature to obtain a mixed powder; S2 . 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; S3. The extruded pipe adopts a Φ90 extruder with a screw The length-to-diameter ratio is 1:28, the screw type is BM type (separate type), and the temperature control is (five-zone heating of the fuselage): 140°C in the first zone, 150°C in the se...

Abstract

The invention relates to a PVC (polyvinyl chloride) hose which is prepared from the invention relates to a PVC (polyvinyl chloride) hose which is prepared from 100 parts of SG-3 PVC resin, 48-56 parts of non-phthalic plasticizer, 0.9-1.3 parts of Ca / Zn composite stabilizer, 0.1 part of stearic acid, 0-0.02 part of whitener, 0-0.02 part of blue ultramarine, 0-1.5 parts of ACR resin and 0-1.5 parts of titanium white. The PVC hose can not cause environmental pollution since no phthalic plasticizer participates; and the disorder of gonadal hormones in the human body causes disorder of sexuality of the human body.

Description

technical field [0001] The invention relates to the field of plastic processing, in particular to PVC hoses. Background technique [0002] Polyvinyl chloride, referred to as PVC in English, is a polymer formed by the polymerization of vinyl chloride monomers in peroxides, azo compounds and other initiators; or under the action of light and heat according to the mechanism of free radical polymerization. Vinyl chloride homopolymers and vinyl chloride copolymers are collectively referred to as vinyl chloride resins. [0003] PVC hose is cheap and good, and it is currently recognized as a better inner pipe for bathroom water pipes, but existing PVC hoses also have deficiencies, such as the Chinese patent "A PVC hose" with application number 201410368284.X discloses a PVC hose, which is made of the following raw materials in parts by weight: 10-20 parts of furfural resin, 7-11 parts of diisononyl phthalate, 4-8 parts of mannitol, 6 parts of ethyl naphthol ~9 parts, 2~4 parts of...
