Abstract

The invention relates to a flame-retardant PVC injection molding material for a branch cable. The flame-retardant PVC injection molding material comprises the following raw materials by weight: 90 to 100 parts of PVC resin, 30 to 60 parts of a plasticizer a, 15 to 25 parts of a plasticizer b, 4 to 8 parts of a heat stabilizer, 8 to 15 parts of a fire retardant, 0.2 to 0.4 part of polyethylene wax, 0.5 to 1 part of a lubricant a, 0.2 to 0.5 part of a lubricant b, 0.3 to 0.8 part of a lubricant c, 2 to 3 parts of a processing modifier and 20 to 50 parts of a filler. The injection molding material has excellent injection molding performance, excellent flame retardation effect and low production cost; and an injection molding product has smooth and fine surface, and the temperature resistance grade of the product reaches 70 to 90 DEG C.

Description

technical field [0001] The invention relates to a cable injection compound and a preparation method thereof, in particular to a flame-retardant PVC injection compound for branch cables and a preparation method thereof. Background technique [0002] Because branch cables have the characteristics of excellent power supply reliability, good shock resistance, air tightness, waterproof, convenient construction, low environmental requirements, and maintenance-free, the application of branch cables in China has been rapidly promoted. With the acceleration of various infrastructure construction and real estate development in our country, the market has continuously increased the application types and performance requirements of branch cables. At present, although domestic manufacturers can prepare flame-retardant PVC injection molding materials for branch cables, the injection molding performance of the products is poor, the injection molding surface is rough and not delicate, the f...
