Abstract

The invention relates to flame-retardant liquid silicone rubber for fabric reinforcement. The flame-retardant liquid silicone rubber for the fabric reinforcement comprises a component A, a component B and a component C, wherein the component A comprises the following components in parts by weight: 100-150 parts of base rubber I, 10-22 parts of a platinum complex and 5-12 parts of a tackifier; the component B comprises the following components in parts by weight: 60-80 parts of base rubber II, 1-9 parts of an inhibitor, 3-8 parts of a silane coupling agent and 0.5-4.2 parts of a diluent; the component C comprises the following components in parts by weight: 15-28 parts of dimethyl methylphosphate, 2-6 parts of magnesium hydroxide, 3-10 parts of sodium hydrogen carbonate, 1.3-2.4 parts of tea saponin, 2.8-4.6 parts of dicyandiamide, 0.2-0.4 part of ethylene glycol and 0.5-0.8 part of acetic anhydride. The flame-retardant liquid silicone rubber for the fabric reinforcement improves the softness and tolerance of fabric, and is environmentally friendly and free of toxic and side effects.

Description

technical field [0001] The invention relates to a liquid silicone rubber, in particular to a flame-retardant liquid silicone rubber for fabric reinforcement. Background technique [0002] The products made of textile fibers through processing and weaving are called textiles. Textiles treated with silicone rubber have soft handle and washing durability. These fiber products coated with silicone rubber have good performance, such as: temperature resistance, Chemical corrosion resistance, high breaking strength and tear strength, etc., have been widely used in construction, flexible connection of electrical insulation pipelines, chemical anticorrosion and sealing and other fields. The traditional silicone rubber coating not only pollutes the environment and affects the health of workers during actual use, but also has hidden dangers of unsafe production. Contents of the invention [0003] Aiming at the above problems, the present invention proposes a flame-retardant liquid s...
