Abstract
The invention provides a method for producing a hot melt adhesive specially used for an aluminum sheath of a railway data signal cable, which is relates to the cable production technical field, especially relates to a method for producing the hot melt adhesive specially used for the aluminum sheath of the data signal cable. The method uses a mode of copolymerization modification and chemical grafting EVA which is a mode by introducing polar gene on an EVA molecular chain, the EVA has good dissolvability with polyethylene resin, the introduced polar gene enables a chemical chain with alumina and film hydroxy on the aluminum metal surface, accordingly, plastics and aluminum sheath can be greatly bonded together. The hot melt adhesive specially used for the aluminum sheath of the data signal cable has good fluidity, enables the cable to reach sealed and waterproof effect, and has good functions of acid resistance, alkali resistance, salt resistance, oxidation resistance and aging resistance.
Description
Technical field
The present invention relates to the cable production technical field, particularly the working method of digital signal cable aluminium sheath hot melt adhesive special.
Background technology
The DM hot melt adhesive is mainly used in the water-tight of railway electrical cable aluminium sheath.Along with the high speed development of China railways, digital data transmission is widely used in the railway cable, and solving digital signal cable aluminium sheath waterproof sealing in for a long time buried is the crux that guarantees railway operation safety.
Summary of the invention
The object of the invention is to propose a kind of working method of hot melt adhesive special of the water-repellancy that can improve the digital signal cable aluminium sheath.
Behind DCP linking agent, 0.1～0.5 weight part antioxidant 1010 and 0.1～0.5 weight part oxidation inhibitor, 168 uniform mixing of the present invention with the Witcodur 272 of the Paris white of the tackifying resin of the EVA resin of 40～50 weight parts, 20～30 weight parts, 15～25 weight parts, 5～10 weight parts, 8～12 weight account polyethylene resins, 1～2 weight part tackifying assistant HO, 0.5～1 weight part; After the adding twin screw extruder is heated and is extruded tie rod, again through water-cooled, pelletizing, oven dry, air-cooled.
The present invention adopts modification by copolymerization and chemistry to connect the mode of skill EVA; Promptly on the EVA molecular chain, introduce polarity gene; Because of EVA and polyvinyl resin have good intermiscibility (wetting property); Introduce polarity gene and can (OH) play chemical chain with aluminum metal surface alumina oxide, film hydroxyl again; Therefore can bond together plastics and aluminium sheath well, so the digital signal cable aluminium sheath hot melt adhesive special that adopts the inventive method to process has following characteristics:
1, because the low curing speed of this product fusing point is fast, insulation causes damage and in very short time gap, carries out sheath processing in use can not be to cable;
2, give crosslinked with silicane material or metals such as Vilaterm and aluminium sheath adhesiveproperties is preferably arranged;
3, have good mobility, can fill up, make cable reach the effect of water-tight because of occurring lacking weldering in aluminium strip joint and the production, leaking and weld the interval that forms;
4, have acid-and base-resisting preferably, salt and resist oxygen aging function, can shield, prolong cable work-ing life electrical cable aluminium sheath.
Embodiment
Working method:
Take by weighing 40～50kgEVA resin, 20～30kg tackifying resin, 15～25kg Paris white, 5～10kg Witcodur 272,8～12kg polyvinyl resin, 1～2kg tackifying assistant HO, 0.5～1kgDCP linking agent, 0.1～0.5kg antioxidant 1010,0.1～0.5kg oxidation inhibitor 168. respectively
Above each raw material of taking by weighing behind the homogenizer uniform mixing, is added twin screw extruder, extrude tie rod through heating after, again through water-cooled, pelletizing, oven dry, air-cooled, packing at last.
Claims (1)
1. the working method of railway digital signal cable aluminium sheath hot melt adhesive special; After it is characterized in that DCP linking agent, 0.1～0.5 weight part antioxidant 1010 and 0.1～0.5 weight part oxidation inhibitor, 168 uniform mixing with the Witcodur 272 of the Paris white of the tackifying resin of the EVA resin of 40～50 weight parts, 20～30 weight parts, 15～25 weight parts, 5～10 weight parts, 8～12 weight account polyethylene resins, 1～2 weight part tackifying assistant HO, 0.5～1 weight part; After the adding twin screw extruder is heated and is extruded tie rod, again through water-cooled, pelletizing, oven dry, air-cooled.
