The invention belongs to the technical field of
flame-retardant wire and cable
processing, in particular to a method for improving the
impact resistance of a thin-wall
flame-retardant wire cable material. The preparation method comprises the following steps: preparing a nano
calcium carbonate composite material, preparing materials, mixing the raw materials, granulating and aging. Compared with the prior art, the preparation method has the following advantages that the preparation of the nano
calcium carbonate composite material reduces the agglomeration tendency, the middle material is compounded with
acrylonitrile-butadiene-
styrene copolymer and then is compounded with high-
polymerization-degree
ammonium polyphosphate at the same time, so that the tensile strength and the
flame retardancy of the obtained
composite material are obviously improved, the resin raw materials with different performances are cooperated, and then aging is carried out after the
electric wire and the cable material are prepared, and a sample strip with the thickness of 0.6 mm is produced, detection is carried out, and the surface of the
wire rod after mechanical scraping is not white, the acid and alkali resistance is good, the flexibility and
impact resistance are relatively good, the environment-friendly and flame-retardant effects are achieved, and poisonous
black smoke cannot be generated during
combustion, and the flexibility and processability are good.
