Preparation method of fire-resistant low-voltage wire cable
The invention relates to the technical field of low-voltage wire and cable production, and discloses a preparation method of a fire-resistant low-voltage wire cable. The fire-resistant low-voltage wire cable is prepared from 5-8 parts of quartz, 2-5 parts of chalcedony, 1-3 parts of opal, 2-4 parts of white silica sand, 5-7 parts of diatomite, 6-8 parts of refractory clay, 2-5 parts of chromite, 1-3 parts of graphite, 2-3 parts of magnesite, 3-5 parts of lime, 5-8 parts of a binding agent and 6-8 parts of an additive. According to the preparation method of the fire-resistant low-voltage wire cable, the acid raw material and the alkaline raw material are combined, so that the two fire-resistant materials cannot be neutralized mutually, the acid raw material and the alkaline raw material canfully play roles, and the acid raw material and the alkaline raw material have relatively strong resistance in a high-temperature state, so that the inner core of the cable can be protected, and damage to the inner core of the cable due to heat preservation is avoided; and the refractory material cannot be combusted after open fire occurs, so that the inner core of the cable is effectively prevented from being burnt or burnt out, and the heat resistance of the low-voltage wire cable is improved.
本发明涉及低压电线电缆生产技术领域，且公开了一种耐火型低压电线电缆的制备方法，包括以下重量份数配比的原料：石英5‑8份、玉髓2‑5份、蛋白石1‑3份、白硅砂2‑4份、硅藻土5‑7份、耐火黏土6‑8份、铬铁矿2‑5份、石墨1‑3份、菱镁矿2‑3份、石灰3‑5份、结合剂5‑8份和添加剂剂6‑8份。该耐火型低压电线电缆的制备方法，通过采用酸性原料和碱性原料相结合，使得两中耐火材料不会出现相互中和情况，让酸性原料与碱性原料能够充分发挥其作用，将高温的状态下通过酸性原料与碱性原料有较强的抵抗能力，能够对电缆的内芯进行保护，避免保温对电缆内芯造成损坏，同时耐火材料不会在发生明火之后燃烧，有效的防止了电缆内芯被或烧损，提高了低压电线电缆的抗热性。
