Abstract

The invention discloses a 150-DEG C irradiation cross-linking anti-blocking halogen-free flame-retardant insulating material and a preparation method thereof. The insulating material comprises the following components in parts by weight: 100 parts of base resin, 100-130 parts of a magnesium hydroxide flame retardant, 1.0-2.5 parts of a coupling agent, 0.5-1 part of an antioxidant and 0.5-3 parts of a silicone master batch lubricant, wherein the base resin comprises ethylene-ethyl acrylate copolymer and styrene- ethylene- butane-styrene segmented copolymer in a weight ratio of (60-85):(10-25). Compared with the prior art, the 150-DEG C irradiation cross-linking anti-blocking halogen-free flame-retardant insulating material disclosed by the invention has the advantages of good processing performance, excellent mechanical performance, high temperature blocking resistance and the like, and is a 150-DEG C irradiation cross-linking anti-blocking halogen-free flame-retardant insulating material satisfying application of UL electron lines.

Description

technical field [0001] The invention relates to a 150°C radiation cross-linking anti-adhesion halogen-free flame-retardant insulating material and a preparation method thereof. Background technique [0002] In the production process of electronic products, after the high temperature resistant electronic wire meeting UL3321 is installed on the electronic product with circuit board, according to the production process, it needs to enter the online baking device. The baking temperature is generally 135 °C ± 5 °C. Baking time is 3-5 minutes. During the baking process, after the wires that are in contact with each other are removed from the oven to cool, the insulation layers of the wires stick together and cannot be separated normally; resulting in the wires being unable to use normally. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art and provide a 150°C radiation cross-linked anti-adhesi...
