Problems solved by technology

[0004] The above technical solution has the following defects: although the bamboo charcoal fiber has good bacteria resistance and reinforcement, the bamboo charcoal fiber material is brittle and easy to break, and it will reduce the toughness of the PVC hose when used in PVC hoses. It is easy to cause the PVC hose to break

Embodiment 1

[0032] Embodiment 1 is a fiber-reinforced PVC hose disclosed by the present invention, which sequentially includes a PVC inner layer, a fiber mesh layer and a PVC outer layer from the inside to the outside. The fiber mesh layer is made of compound fibers, and the compound fibers are polystyrene Ethylene / ramie fiber / ABS resin fiber, the mass ratio of polystyrene, ramie fiber and ABS resin is 3:2:12.5;

[0033]The preparation method of polystyrene / ramie fiber / ABS resin fiber is: 1) ramie fiber is pulverized into fiber length and is 3mm, and the fine debris of fiber diameter is 15um standby; 2) polystyrene is dissolved in acetone solution, and then Add the ramie fiber fines into the polystyrene solution, and stir evenly to obtain a blend; 3) heat the ABS resin to a molten state, and then mix 3% of the total weight of the ABS resin with the mica powder in step 2) Add the blend into the ABS resin melt and stir evenly; 4) Extrude the uniformly stirred mixture in step 3) into strips,...

Embodiment 2

[0043] Embodiment 2 is a fiber-reinforced PVC hose disclosed by the present invention. The difference from Embodiment 1 is that the PVC inner layer and the PVC outer layer include the following components in parts by weight: 75 parts of PVC resin, wear-resistant filler 5 parts, 5 parts of anti-aging masterbatch, 4 parts of phthalate and 1 part of polyethylene wax.

Embodiment 3

[0044] Embodiment 3 is a fiber-reinforced PVC hose disclosed by the present invention. The difference from Embodiment 1 is that the PVC inner layer and the PVC outer layer include the following components in parts by weight: 95 parts of PVC resin, wear-resistant filler 15 parts, anti-aging masterbatch 10 parts, phthalate ester 8 parts and polyethylene wax 3 parts.

Abstract

The invention relates to the technical field of tube materials, in particular to a fiber reinforced PVC flexible tube. The flexible tube successively comprises a PVC inner layer, a fiber web layer anda PVC outer layer from inside to outside. The flexible tube is characterized in that the fiber web layer is made of compound fibers, and the compound fibers are polystyrene fibers or ramine fibers orABS resin fibers. The PVC inner layer and the PVC outer layer are prepared from the components in parts by weight: 75 to 95 parts of PVC resin, 5 to 15 parts of wear-resisting packing, 5 to 10 partsof an anti-aging master batch, 4 to 8 parts of a plasticizer and 1 to 3 parts of a lubricant. The PVC flexible tube has the advantages of being not prone to fracture and strong in pressure resistance.

Description

technical field [0001] The invention relates to the technical field of pipes, in particular to a fiber-reinforced PVC hose. Background technique [0002] Hose is widely used in media transportation and hydraulic transmission, etc. It plays an important role in the development of the national economy. According to the material, hoses can be divided into three types: metal hoses, rubber hoses and plastic hoses. Metal hoses are only used in certain specific working environments, and their adaptability and usage are limited. With the development of new materials and the development of production technology and equipment, rubber hoses have advantages in the scope of use, adaptability and usage. Plastic hose is a new product that has been vigorously developed in recent years. With the development of synthetic resin technology, the development of plastic modifiers, the progress of process equipment, and the many advantages of plastic hose itself, it has a tendency to replace other...
