Abstract

The invention discloses a hose and a preparation method thereof. The preparation method comprises a step of weighing PVC, N-butylphthalimide, zinc stearate, calcium stearate, epoxidized soybean oil, DOP, DBP, DOA, barium stearate, cadmium stearate, di-n-octyl phthalate, stainless steel metal powder, di-n-butyltin dilaurate and ACR. The hose has a bending strength of 80-100MPa and an impact strength of 30-50 kJ / m<3>; the hose is resistant to high temperature of 120-160 DEG C, and has a tensile strength of 55-95MPa; the hose is self-extinguishing in the case of being away from fire, non-toxic and sanitary, and has an elongation at break of 420-480%; and the hose is resistant to drop-hammer impact, has an elasticity modulus of 1.9-2.3GPa, and can be widely produced and continuously replace the existing material.

Description

technical field [0001] The invention relates to the field of pipe materials, in particular to a hose and a preparation method thereof. Background technique [0002] Hoses are vital components in modern industry. Hoses are mainly used as wire and cable protection tubes for wires, cables, automated instrument signals, and civil shower hoses, with specifications ranging from 3mm to 150mm. Small-diameter hoses (inner diameter 3mm-25mm) are mainly used for the protection of sensing lines of precision optical scales and the protection of industrial sensor lines. [0003] Annular corrugated pipe is a tubular shell with corrugations in the shape of a closed ring, and the waves are connected in series by ring corrugations. Annular bellows are formed from seamless or welded pipes. Restricted by the processing method, the length of a single tube is usually shorter than that of a spiral corrugated tube. The advantages of annular bellows are good elasticity and low rigidity. [00...
