Wear-resistant and oil-proof PVC elevator cable material and preparation method thereof

Abstract

The invention discloses a wear-resistant and oil-proof PVC elevator cable material. The wear-resistant and oil-proof PVC elevator cable material consists of the following raw materials in parts by weight: polyvinyl chloride resin 100 parts, a rubber and plastic component 10-40 parts, a plasticizer 40-60 parts, epoxy soybean oil 3-5 parts, a filler 10-50 parts, wear-resistant powder 2-10 parts, a thermal stabilizer 2-5 parts, an oxidation inhibitor 0.25-1.5 parts, a lubricant 0.1-1 part, and a modifier 0.5-2.5 parts. The invention further discloses a preparation method of the wear-resistant and oil-proof PVC elevator cable material. The preparation method comprises the following steps: first step, preparing raw materials, and accurately weighing various materials proportionally; second step, mixing the materials uniformly and carrying out preplasticizing; third step, extruding, mixing and pelleting by a double-stage double-screw extruder, wherein the temperature range of the extruder is 140-175 DEG C; fourth step, cooling, sieving and carrying out magnetic separation; and fifth step, packing and storing.

Description

technical field [0001] The invention relates to the field of cables, in particular to a wear-resistant and oil-resistant PVC elevator cable material and a preparation method thereof. Background technique [0002] PVC (polyvinyl chloride) resin is a synthetic material that is loved, popular and widely used in the world today. Its global usage ranks second among various synthetic materials, second only to polyethylene resin. In daily life, PVC can be used in the manufacture of sandals, raincoats, toys and artificial leather, etc. Due to its excellent electrical insulation performance, it can be used in the electrical and electronic industries to manufacture plugs, sockets, switches and cables. [0003] After decades of development, the manufacturing process of ordinary PVC cable materials in my country has been quite perfect, and the formula of conventional PVC cable materials has long been mature and stable. However, with the continuous development of the economy and the im...

Problems solved by technology

However, when the wear resistance and oil resistance are increased by introducing other components and fillers, it is easy to cause a series of problems such as increased hardness and decreased flexibility of the elevator cable after being cabled, thus affecting customer use.
