Abstract

The invention relates to a modified organic silicon polymer paint for preventing a power transmission wire from covering ice and a preparing method thereof. The paint comprises the following components in parts by weight: 40-50 parts of functional polymer, 45-55 parts of functional vacuum cenospheres wrapped by fluorinated siloxane, 1-2 parts of functional auxiliary, 0.1-0.3 part of defoaming agent and 2-5 parts of polytetrafluoroethene emulsion wax. Compared with the prior art, the invention has the advantages of low surface tension, high hydrophobicity, high self-lubricity, low bonding property to ice, proper heat absorption, insulating and storage property, excellent adhesion to a cable, excellent outdoor use durability, refractory, environment-friendly and non-toxic film forming matter and the like.

Description

technical field [0001] The invention relates to a functional polymer for cable anti-icing coating, in particular to a modified organosilicon polymer transmission line anti-icing coating and a preparation method thereof. Background technique [0002] Cable icing is affected by various factors such as temperature, humidity, cold and warm air convection, circulation and wind speed, resulting in different types of conductor icing, which can be roughly divided into five types. [0003] A Rime icing: It is icing that occurs in low-altitude areas during the freezing rain period. The duration is generally short. Very high, rime icing is the initial stage of mixed rime icing. [0004] B mixed rime: When the temperature is below freezing point and the wind is strong, mixed rime is formed. Under the condition of mixed rime icing, the freezing of water droplets is relatively weak, the icing is sometimes transparent and sometimes opaque, and the ice has a strong adhesive force on the w...
