Abstract
Disclosed is a flame-retardant hot-melt adhesive to be applied to the inner surface of a heat-shrinkable tube, It contains 100 parts by weight of a resin composition having an MI value (190.degree. C.) of 30-220, 5-40 parts by weight of a chloric or bromic flame-retardant, 1-30 parts by weight of an inorganic flame-retardant and 0.1-20 parts by weight of fine powder having an average particle diameter between 0.01 and 40 microns. It is a flame-retardant adhesive which shows good fluidity when subjected to external force and no dropping occurs if it burns.
Claims6
A flame-retardant adhesive comprising 100 parts by weight of a resin composition having an MI value (at 190.degree. C.) of 30-220, 5-40 parts by weight of a chloric or bromic flame-retardant wherein said chloric flame-retardant contains 65 wt % or more of chlorine and said bromic flame-retardant contains 80 wt % or more of bromine, 1-30 parts by weight of an inorganic flame-retardant and 0.1-20 parts by weight of silica powder having an average particle diameter of 0.01 to 40 microns.
A heat-shrinkable tube comprising a heat-shrinkable tube body having an inner and outer surface, and a flame-retardant adhesive applied to said inner surface, said flame-retardant adhesive comprising 100 parts by weight of a resin composition having an MI value at (190.degree. C.) of 30-220, 5-40 parts by weight of a chloric or bromic flame retardant, wherein said chloric flame-retardant contains 65 wt % or more of chlorine and said bromic flame-retardant contains 80 wt % or more of bromine, 1-30 parts by weight of an inorganic flame-retardant and 0.1-20 parts by weight of silica powder having an average particle diameter of 0.01 to 40 microns.
A harness having a waterproof joint portion, said joint portion being covered with a heat-shrinkable tube comprising a heat-shrinkable tube body having an inner and outer surface and having a flame-retardant adhesive applied to said inner surface, said flame-retardant adhesive comprising 100 parts by weight of a resin composition having an MI value (at 190.degree. C.) of 30-220, 5-40 parts by weight of a chloric or bromic flame retardant, wherein said chloric flame-retardant contains 65 wt % or more of chlorine and said bromic flame-retardant contains 80 wt % or more of bromine, 1-30 parts by weight of an inorganic flame-retardant and 0.1-20 parts by weight of silica powder having an average particle diameter of 0.01 to 40 microns.
