Embodiment 1

[0018] Put 60 parts of PVC resin, 6 parts of fluorinated polyethylene, 1 part of fluorosilicon emulsion, 0.5 parts of calcium zinc stabilizer, 6 parts of synthetic vegetable fat, 18 parts of dioctyl phthalate, and 1.5 parts of calcium carbonate into the high-speed mixer In the process, the kneading temperature is 115°C, and the stirring time is 10 minutes, then it is sent to a low-speed cooling mixer, and when it is cooled to 35°C, it is extruded to obtain a PVC pipe.

Embodiment 2

[0020] Put 70 parts of PVC resin, 7 parts of fluorinated polyethylene, 2 parts of fluorosilicon emulsion, 0.7 parts of calcium zinc stabilizer, 8 parts of synthetic vegetable fat, 24 parts of dioctyl phthalate, and 2 parts of calcium carbonate into the high-speed mixer In the process, the kneading temperature is 115°C, and the stirring time is 10 minutes, then it is sent to a low-speed cooling mixer, and when it is cooled to 35°C, it is extruded to obtain a PVC pipe.

Embodiment 3

[0022] Put 80 parts of PVC resin, 8 parts of fluorinated polyethylene, 3 parts of fluorosilicon emulsion, 1 part of calcium zinc stabilizer, 11 parts of synthetic vegetable fat, 33 parts of dioctyl phthalate, and 3 parts of calcium carbonate into the high-speed mixer In the process, the kneading temperature is 115°C, and the stirring time is 10 minutes, then it is sent to a low-speed cooling mixer, and when it is cooled to 35°C, it is extruded to obtain a PVC pipe.

Abstract

The invention relates to a PVC hose, which is prepared by: putting 60-80 parts of PVC resin, 6-9 parts of an anti-impact agent, 1-3 parts of a softening agent, 0.5-1 part of a composite stabilizer, 25-45 parts of a plasticizer, and 1.5-3 parts of calcium carbonate into a high-speed mixer, keeping the kneading temperature at 115DEG C, and performing stirring for 10min, then sending the mixture into a low speed cooling mixing machine to perform cooling to 35DEG C, and then conducting extrusion molding to obtain the PVC pipe. By using fluorinated polyethylene as the anti-impact agent and then adding calcium carbonate, toughness of the PVC hose is improved, and certain rigidity is maintained while the impact resistant ability is increased.

Description

technical field [0001] The invention relates to a plastic pipe, in particular to a PVC hose. Background technique [0002] PVC hose, the main component is polyvinyl chloride, mainly used as pvc water pipes, pvc baseboards, etc., and threading pipes, etc. , ductility, etc., to improve the physical properties of PVC hoses. However, the flexibility of PVC hose is not enough, it is not resistant to low temperature, and it cannot resist impact. These are still the shortcomings of PVC hose. It needs to be improved to increase the adaptability of PVC hose to the environment. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a PVC hose, which has high toughness and impact resistance. [0004] In order to solve the above problems, the technical solution of the present invention is 1. A PVC hose is characterized in that it consists of the following raw materials in parts by weight: [0005] PVC resin 60~80 parts [0006...
