Abstract

The invention discloses a novel heat resistant coating, which is prepared from the following raw materials (by weight): 3.5-7.5 parts of a ultraviolet light absorber, 2-5 parts of diisooctyl succinate sulfonate, 4.3-5.6 parts of 3-chloro-2-hydroxypropyltrimethylammonium chloride, 4-6 parts of N-alkylacylsarcosinate, 3.2-5.4 parts of sorbitol monooleate, 2.5-3.5 parts of T203, 8.5-10.8 parts of an emulsion, 0.1-0.2 part of an anti-aging agent, and 0.15-0.32 part of sorbitol fatty acid ester. The coating has low environment pollution, can be used as an environmental protection material, has advantages of high production efficiency, low energy consumption and low cost, has improved heat resistance and water resistance, and will not lead to loss of photosignal or reduction of adhesive strength even if being immersed in water at high temperature for a long time. Thus, optical fibre of the invention shows improved heat, mechanical and chemical stability, and especially has no delamination phenomenon when immersed in water at 45-85 DEG C for a long time. Water resistance and adhesive strength of a glass fibre substrate are enhanced. The product has high heat, mechanical and chemical stability.

Description

technical field [0001] The invention relates to a coating, in particular to a novel heat-resistant coating and a preparation method thereof, belonging to the coating field. Background technique [0002] Optical fibers used in the electronics, information processing, and telecommunications fields are constructed of UV-curable coatings with low impact strength that are applied to minimize deformation of the fibers or loss of optical signals. Such coatings are required to have properties that minimize undesirable effects caused by changes in the external environment, especially water penetration, and are also required to impart improved tensile strength and other properties to the coating without causing degradation of the optical signal. Compositions comprising organosiloxanes are known to provide coatings meeting the above requirements, having a low glass transition temperature and good hydrophobicity, however, it is difficult to prepare coatings that are uniform and have sat...
