Embodiment
The application provides a kind of flame-retardant smoke inhibition supplying pipe, which mainly includes：It is polyvinyl chloride, lubricant, steady
Determine agent and anti-flaming smoke-inhibiting agent, wherein fire retardant mainly includes：Palygorskite, silane coupler modified Mg (OH)2, silane coupling agent
Modified nano imvite, the Nano-meter SiO_2 of titanate coupling agent modified2, below to the raw material that is used in the embodiment of the present application into
Row detailed description：
Polyvinyl chloride, the thermoplastic resin being polymerized by vinyl chloride under initiator effect.PVC is that yield is most in the world
Big general-purpose plastics, using very extensive.In construction material, industrial product, daily necessities, flooring laminate, floor tile, artificial leather, pipe
Material, electric wire, packaging film, bottle, expanded material, sealing material, fiber etc. are widely used.
Palygorskite, containing ignition-proof element magnesium, the aluminium water different with property, such as the crystallization water, hydroxyl structure water, zeolite molecules water
With inclusion water etc., palygorskite abundant raw material, cost is low, is readily processible to the particulate of nano-micrometre level.Palygorskite has very big
Specific surface area and adsorption capacity, the microcellular structure on its surface, has gas strong suction-operated, can heat-insulated thermal insulation, block heat
Transmit, simultaneously because its good water suction and water retention property, can produce vapor and block oxygen, have good resistance at high temperature
Combustion acts on, and is one of preferable flame-retardant additive.And compared with other fire proofings, palygorskite also have light weight, it is wear-resisting, go out
Bacterium, it is nontoxic the advantages that.
Silane coupler modified Mg (OH)2, Mg (OH)2It is a kind of white amorphous powder, Mg (OH)2With good
Flame retarding and smoke suppressing properties, frequently as fire retardant, smoke suppressant, filler and the rubber plastic industry that is widely used.Mg(OH)2Heated hair
It can be discharged during solution estranged with reference to water, while decomposable process can absorb substantial amounts of heat, so that temperature of the material in fire is reduced,
The decomposition of material is prevented, while can also play the role of cooling to the imflammable gas of generation.In addition Mg (OH)2Produced after decomposition
Magnesia, magnesia have good flame-retardant performance in itself, help to lift the fire resistant flame retardant performance of material in itself.And divide
The vapor produced in solution preocess can be used as inhibitor, reduce the concentration of flue dust in environment, and adding in supplying pipe to have
The flame retarding and smoke suppressing properties of the raising water pipe of effect.But hardness and rigidity due to inorganic material in itself, tubing during meeting after addition
Mechanical property has declined.
Silane coupling agent is that the group such as low molecular organo-silicon compound, its alkoxy contained, acyloxy can be with hydrogen-oxygen
Change the hydroxyl effect that magnesium surface carries, processing is modified to it.Modified Mg (OH)2Surface carries part organic group,
Surface is changed into hydrophobicity from hydrophily, helps to improve its dispersiveness in PVC base system, and then improve modified
Mg (OH)2With the compatibility performance and adhesive strength of pvc material, Mg (OH) is reduced2In filling to material mechanical performance
Influence；Mg (OH) modified at the same time2The rigidity and hardness on surface decrease, and are advantageously reduced after being filled as fire retardant
Its influence to supplying pipe mechanical property.
Silane coupler modified nano imvite, montmorillonite are a kind of natural minerals of silicate, are bentonite ore
Essential mineral component.Montmorillonite has good fire resistance, and class montmorillonite filled material has huge ratio when fire occurs
The lamellar structure of surface area can voluntarily be enriched to polymer combustion surface in combustion, form the silicic acid of dense refractory
Salt barrier layer, delays polymeric inner to decompose the small molecule that produces to surface migration and extraneous oxygen to burning surface and polymerization
Thing diffusion inside, so as to improve the anti-flammability of material.When scattered easily it is in state of aggregation yet with montmorillonite, it is easily scattered,
And its surface hydrophilicity is stronger, it is not easy to disperse after filling polyvinyl chloride, reduces the mechanical property of tubing.
The acidified rear surface of montmorillonite can expose more hydroxyl, after silane coupler modified, its surface oleophylic
Property enhancing, be conducive to improve its dispersiveness in pvc material, while reduce the rigidity and hardness of montmorillonite in itself, drop
The low class montmorillonite filled influence to mechanical properties of tubular goods, while assign tubing good fire resistance.Use in the present embodiment
Length is modified for 50~150nm nano imvites, and nano material has larger surface area, is conducive to lift material
Fire resistance, while there is good fillibility.
In the present embodiment, the silane coupling agent used includes：A174、A187、KH590、KH550.A174、A187、
KH590, KH550 are to Mg (OH)2, nano imvite there is higher cladding area, modification degree is preferable, can be effectively to Mg
(OH)2, nano imvite is modified.
The Nano-meter SiO_2 of titanate coupling agent modified2, SiO2It is one of most important oxide of silicon, its high temperature can decompose generation
Silicate, has a good flame retarding and smoke suppressing properties, but Nano-meter SiO_22Easily reunite, when being dispersed in pvc material,
Its dispersion performance is poor, can reduce the mechanical property of material.
Titanate coupling agent is to Nano-meter SiO_22It is modified, its surface also have it is hydrophilic be changed into hydrophobic, it is preferably disperseed
In polyvinyl chloride, modified SiO is lifted2With the compatibility of material, so as to reduce SiO2Influence to the mechanical property of tubing,
While reaching imparting tubing fire resistance, and do not influence mechanical properties of tubular goods.In the present embodiment using a diameter of 100~
200nm Nano-meter SiO_2s2It is modified, nano material has larger surface area, is conducive to be lifted the fire resistance of material, at the same time
With good fillibility.
Palygorskite that anti-flaming smoke-inhibiting agent includes, silane coupler modified Mg (OH)2, silane coupler modified nanometer
Montmorillonite, the Nano-meter SiO_2 of titanate coupling agent modified2Good fire resistance is respectively provided with, is mixed and adds polyvinyl chloride material
In material, supplying pipe is obtained, the synergistic effect between each fire retardant matter can effectively improve the flame retarding and smoke suppressing properties of material, realize water
The flame retarding and smoke suppressing properties of pipe, improve the security used.
Lubricant, the effect of lubricant are the frictional force reduced between polymer and equipment, and polymer molecular chain it
Between frictional force.Common lubricant mainly has silicone oil, paraffin, monoglyceride, metal soap, stearyl alcohol and esters etc..Lubricant
Type be not limited in this application, specifically, those skilled in the art can make choice according to service condition.
Stabilizer, the chloro that polyvinyl chloride contains is easily substituted, causes the degraded of polyvinyl chloride, therefore in polyvinyl chloride water
Pipe needs to add stabilization aid during making.Common stabilizer mainly has lead salt stabilizer, barium cadmium stabilizer, the calcium zinc class steady
