Abstract
The present invention relates to a low smoke flame-retardant cable covering tape without halide and a manufacturing technology thereof. The low smoke flame-retardant cable covering tape without halide adopts polyester staple fibre as frame material, the polyester staple fibre is dipped with a low smoke flame-retardant adhesive without halide, and through drying operation, the low smoke flame-retardant cable covering tape without halide is manufactured. The low smoke flame-retardant adhesive without halide is prepared from the following raw material according to the weight compounding ratio: 120 to 300g of flame retardant, 6 to 10g of suspending agent, 10 to 20g of adhesive and 160 to 500g of water. According to a product of the present invention, the periphery of the polyester staple fibre is filled with inorganic hydroxide flame-retardant material. When a cable is on fire, inorganic hydroxide can release a large quantity of moisture, the moisture becomes steam, the temperature of the cable which is on fire is reduced, the continuous combustion of the cable is prevented, and the self extinguishing function is realized. After the moisture of the inorganic hydroxide is thoroughly released, the inorganic hydroxide becomes refractory oxide, no harmful gas can be generated, and therefore, requirements of fire protection and environmental protection are satisfied.
Description
Technical field
The present invention relates to a kind of Low smoke flame-retardant cable covering tape without halide and manufacturing process, relate to a kind of cable of making by framework material terylene short fiber peacekeeping LSOH anti-flaming adhesive specifically with fire-retardant band and manufacturing process.
Background technology
At present, because the fire injures and deaths that power supply causes are more outstanding, cables manufacturing is already through developing multiple difficult combustion and flame retardant cable and fire-retardant band thereof in the discussion of making great efforts, especially meeting environmental protection fire-fighting requirement LSOH anti-flaming band presses for especially, but also contain efficient fire proofing such as chlorine bromine (halogen) phosphorus ether so far and make fire retardant in employing, but this fire retardant can produce a large amount of flue dust and poison gas when ignition of cable, causes that people are poisoned to death in the scene of a fire.
On August 9th, 2000, the inventor disclosed a kind of novel flame-retardant tape for cables (ZL9924497) though after having solved ignition of cable, band does not produce the problem of poison gas and flue dust, can satisfy the requirement of environmental protection and fire-fighting, but from manufacturing process, it also exists shortcoming, it will be finished by two production lines, article one, production line is produced fire-retardant band base cloth (nonwoven fabrics), on the second production line, base cloth two sided coatings flame-retardant layer is made fire-retardant band, production procedure is long, investment is many, and producing cost is big, and in secondary fabrication processes, all must adopt adhesive, if adhesive content is many, flame retardant agent content influences fire resistance with regard to relative having lacked, and therefore must improve composition and the manufacturing process of existing cable with fire-retardant band.
Summary of the invention
It is better to the objective of the invention is to design a kind of fire resistance, and Low smoke flame-retardant cable covering tape without halide that one-step method forms and manufacturing process are to overcome the deficiencies in the prior art.
The object of the present invention is achieved like this, and it is the skeleton material with the polyester staple fiber, and behind dipping LSOH anti-flaming adhesive, oven dry forms, and it is characterized in that: described LSOH anti-flaming adhesive is to be made by the following weight proportion raw material:
1. AL (OH)
3Or Mg (OH)
2Or both blends: 120-300g,
(2) 1788 or 1799PVA resin: 6-10g,
3. the 707VAE latex of solid content 55%: 10-20g,
4. water: 160-500g.
The manufacturing process of Low smoke flame-retardant cable covering tape without halide is characterized in that by following step manufacturing:
1. make the skeleton material, polyester staple fiber made fiber roll,
2. prepare the LSOH anti-flaming adhesive,
(1) get the raw materials ready, weigh by following weight proportion,
AL (OH)
3Or Mg (OH)
2Or both blends: 120-300g,
1788 or 1799PVA resin: 6-10g,
The 707VAE latex of solid content 55%: 10-20g,
Water: 160-500g,
(2) above-mentioned weight 1788 or 1799PVA resin are added 10 times hot water, fully dissolving, cool to room temperature, the aqueous solution, stand-by,
(3) the 707VAE latex of above-mentioned weight solid content 55% is mixed with the 707VAE glue of 8.5% solid content,
(4) with step 2. and 3. resulting liquid mix, the basic glue of furnishing,
(5) with the AL (OH) of above-mentioned weight
3Or Mg (OH)
2Or both blends add in the basic glue, promptly get the LSOH anti-flaming adhesive,
3. after fiber roll must being flooded the LSOH anti-flaming adhesive by padder, after the padder roll rolled unnecessary LSOH anti-flaming adhesive, the drying machine was dried again, and rolling promptly gets the Low smoke flame-retardant cable covering tape without halide blank,
4. with blank, compacting, cut, one-tenth dish, arrangement, packing, become product of the present invention.
The present invention compared with prior art, product of the present invention is at polyester staple fiber inorganic hydroxide fire proofing abrim all around,, when ignition of cable, inorganic hydroxide can discharge large quantity of moisture, and become steam, and reduced the temperature of the cable that catches fire, stop the combustion of prolonging of cable, and can play from putting out effect, after the release of inorganic hydroxide moisture content finishes, just become the oxide of infusibility, can not produce any pernicious gas again, satisfied the fire-fighting environmental requirement.
