Embodiment
[0016] The invention discloses a production process of a flame retardant adhesive tape. The flame retardant adhesive tape comprises a fabric substrate, a waterproof insulating adhesive layer compounded on the inner surface of the fabric substrate, and a flame retardant adhesive layer coated on the surface of the waterproof insulating adhesive layer. The waterproof insulating adhesive layer is controlled at 0.4-2mm.
[0017] Specifically, the production process includes the following steps:
[0018] Step 1, preparation of a fabric base material; woven into a fabric base material with a plain weave structure through flame retardant yarns. The flame-retardant yarn adopts a core-spun yarn structure, with aramid fiber as the core yarn and methyl fiber as the wrapping fiber. The fabric base material has high structural strength, and both aramid fiber and methyl fiber have good flame retardant properties. Aramid fiber has high elastic modulus, high tensile strength, and good flame r...

Description
technical field [0001] The invention relates to the field of foam rubber, in particular to a production process of a flame retardant adhesive tape. Background technique [0002] Polymers can cause or spread flames in most cases because they are organic compounds with flammable properties that decompose into unstable flammable objects when heated. In the field of electronics, the requirements for fire protection are more important for the manufacture of electronic products that are widely used in daily life. For electronic products with complex internal structures, a spark generated by a short circuit of a wire can lead to the destruction or even combustion of the entire electronic product. The research and development of flame retardant tape is to meet the statutory fire protection requirements. The main function of flame retardant tapes is to effectively slow down the burning or decomposition of polymers to avoid flames. The existing flame retardant tape has unsatisfacto...
