Abstract

The invention provides a halogen-free flame retardant insulation material used for a photovoltaic cable, which belongs to a novel cable material technical field and solves the problems exiting in the present halogen-free flame retardant insulation material used for the photovoltaic cable, that is, poor mechanical properties of tensile strength, elongation break and the like, poor heat aging property, shorter service life, and the like. The halogen-free flame retardant insulation material used for the photovoltaic cable comprises the following components according to a weight ratio: a 100 proportion of base material, 8-35 proportion of flame retardant, 2-8 proportion of stabilizer, and 1-10 proportion of crosslinking sensitizer. The halogen-free flame retardant insulation material used for the photovoltaic cable has the advantages of low production cost, good mechanical properties as heat aging property, tensile strength, elongation break and the like, long service life, low temperature tolerance, ozone resistance, weather resistance, direct current voltage resistance, and dynamic penetration resistance, etc.

Description

technical field [0001] The invention relates to an insulating material for cables, in particular to a radiation-crosslinkable halogen-free flame-retardant insulating material for photovoltaic cables; it belongs to the technical field of new cable materials. Background technique [0002] With the sharp reduction in the production cost of polysilicon, the raw material of solar cells, and the improvement of solar cell production technology, the output of solar cells in the world has increased very rapidly in recent years, which is called a sunrise industry. According to statistics, the annual output of solar cells in the world was 387 megawatts in 2000, 540 megawatts in 2002, 742 megawatts in 2003, 1195 megawatts in 2004, and 1700 megawatts in 2005, with an annual increase of 30%. ~60%. The market demand for photovoltaic cables for solar cells is also growing rapidly. [0003] Since photovoltaic cables are often used under harsh environmental conditions, such as high and low ...
