Wear-resistant PVC hose with high toughness and processing method thereof

Abstract

High toughness wear-resistant PVC hose and its processing method, a layer of ribs is processed between the inner layer and the outer layer of the pipe body, the inner layer of the pipe body is an elastic layer composed of high toughness material, and the outer layer of the pipe body is A wear-resistant layer made of wear-resistant materials is added, and the rib layer is braided by a series of nylon threads. It mainly includes the following processing steps: Extrude the inner layer raw material from the first screw extruder, cool down to form the inner layer of the pipe body, use the braiding machine to weave the rib layer on the surface of the inner layer, and use the second screw extruder to Extrude an outer layer covering the rib layer to form the tube body. Adopting this technical solution, since the rib layer is made of nylon wire interlaced in a network shape, the upper, lower, left, and right ribs are interlinked together, the tensile strength and dismantling resistance strength are enhanced, and the elasticity of the pipe body is enhanced. Since the inner and outer layers of the hose are designed according to the use environment, the outer layer is made of wear-resistant materials and the inner layer is made of high-toughness materials. The structure of the hose body is more reasonable and the service life is longer.

Description

technical field [0001] The invention belongs to the technical field of PVC plastic hoses, and relates to a high-toughness wear-resistant PVC hose and a processing method thereof. Background technique [0002] In the prior art, a PVC plastic hose is composed of an inner layer, an outer layer, and a rib layer sandwiched between the inner and outer layers. The inner layer and the outer layer are made of the same material, and the rib layer is formed by extrusion molding on the inner layer of the hose. Finally, the ribs are wound forward for one layer, and then reversely wound on the inner layer, and then the outer layer of the hose is squeezed outside the ribs layer. The PVC plastic hose processed in this way is only layer by layer due to the forward and reverse winding ribs on the inner layer, and no cross connection between the wire layers is formed. Its tensile and folding resistance , rebound and other mechanical properties are relatively poor. The inner layer and the out...

Problems solved by technology

[0003] Aiming at the problems in the prior art that the rib structure of the PVC plastic hose is unreasonable and the design of the inner and outer layers is unreasonable, the present invention provides a high-toughness wear-resistant PVC hose, which is placed between the inner layer and the outer layer of the pipe body. A layer of ribs is processed. The inner layer of the pipe body is an elastic layer made of high-toughness materials. The outer layer of the pipe body is a wear-resistant layer made of added wear-resistant materials. The ribs layer is woven with nylon threads. Winding on the inner layer, the upper line of the winding is pulled out of the concave ferrule, the down line passes through the ferrule, and the down line is also pulled out of the downward ferrule at the position of the ferrule, and the next line The wire is wound and passed through the ferrule, and the coil is connected to form a rib layer
