Embodiment 1

[0019] Embodiment one: if figure 1 and figure 2 Shown: a high-toughness wear-resistant PVC hose, a layer of ribs 4 is processed between the inner layer 1 and the outer layer 2 of the pipe body, and the inner layer 1 of the pipe body is an elastic layer composed of high-toughness material. The outer layer 2 of the body is a wear-resistant layer made of wear-resistant materials, and the rib layer 4 is woven with nylon thread, which is wound on the inner layer 1 circle by circle, and the upper line of the winding line is pulled out of the concave sleeve. Circle 3, the downline passes through the loop 3, the downline is also pulled out of the downward loop 3 at the position of the loop 3, and the next line of winding passes through the loop 3, and the coils are connected to each other. The sleeve forms a rib layer; the high-toughness material constituting the inner layer 1 of the pipe includes sheet materials in parts by weight: 30 parts of PVC-5 resin, 0.5 part of 901 light sta...

Embodiment 2

[0020] Embodiment two: the high-toughness wear-resistant PVC hose as described in embodiment one, its processing method comprises the following steps,

[0021] 1. Calculated in parts by weight, the raw materials that will constitute the inner layer of the pipe, PVC-5 resin: 30 parts, 901 light stabilizer: 0.5 parts, styrene-butadiene rubber: 5 parts, disproportionated rosin: 0.6 parts, stearamide: 1 Parts, Diethylene glycol monomethyl ether: 0.6 parts; Stir evenly in the first high-speed mixer;

[0022] Put the uniformly stirred inner layer raw materials into the first screw extruder and heat to 130 0 C. Extrude from the extrusion head, and circulate and cool the melted raw material with purified clean water at normal temperature on the forming die of the pipe body to cool it down to 80 0 Below C forms the inner layer of the pipe body;

[0023] 2. Install the netting machine after the first screw extruder, let the inner layer of the pipe body pass through the braiding head o...

Abstract

The invention provides a high-toughness abrasion-resistant PVC hose and a processing method thereof. A rib line layer is processed between an inner layer and an outer layer of a hose body. The inner layer of the hose body is an elastic layer made of a high-toughness material. The outer layer of the hose body is an abrasion-resistant layer made of an additive abrasion-resistant material. The rib line layer is formed by sleeving and weaving nylon lines in an interlinked mode. The processing method of the high-toughness abrasion-resistant PVC hose mainly comprises the following steps that the inner-layer raw material is extruded through a first screw extruder and cooled to form the inner layer of the hose body, the rib line layers are woven on the surface of the inner layer through a net weaving machine, and one of the rib line layers is extruded through a second screw extruder to cover the outer layer on the rib line layer, so that the hose body is formed. According to the adopted technical scheme, due to the fact that the rib line layer is formed by weaving the nylon lines in a net shape and intersected mode, and upper, lower, left and right rib lines are connected together in an intersected mode, the tensile strength and the tear-resistant strength of the rib line layer and the elasticity of the hose body are enhanced; and because the inner layer and the outer layer of the hose are subjected to function division design according to the using environment, the outer layer is made of the abrasion-resistant material, and the inner layer is made of the high-toughness material, so that the structure of the hose body is more reasonable, and the service life of the hose body 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...
