The stereo garage provided by the invention is environmentally-friendly, and has high flame retardance.
Description
Technical field
The present invention relates to a kind of multi-storied garage, the flame retardant type multi-storied garage of especially a kind of hydrogen sulfide corrosion-resistant, non-environmental-pollution.
Background technology
The purpose of multi-storied garage is to park the automobile of greater amt on unit surface, and automobile is intensive to be parked, and has saved the space, but brings no small potential safety hazard.If catch fire, may cause a chain of fire, be difficult to reach the fire-fighting effect.One of present preventive measures are to lay flame-retardant cushion in multi-storied garage, and due to the damping capacity of rubber cushion excellence, can also reduce the noise that Automobile parking produces.
In addition, for the selection of flame-retardant system, the focus of current flame retardant area is to reduce and limit the use of halogen flame, the halogen-free flame-retardant system of development low-smoke low-toxicity gaseous emission.Wherein, the phosphor nitrogen combustion inhibitor flame retardant resistance is strong, and cigarette, toxicity and corrosive gases burst size are low, and flame retarding efficiency has overcome the inorganic combustion inhibitor loading level large higher than inorganic combustion inhibitor, has a strong impact on the shortcoming of Polymer Mechanical performance.
Traditional nitrogen phosphorus fire retardant is generally take ammonium polyphosphate (APP) as the basis, tetramethylolmethane is done carbon source, tricarbimide melamine salt (MCA) is done source of the gas, have very large defective in use: the APP nitrogen content is high, and flame retardant effect is excellent, is easy to other fire retardant and coordinates, but water absorbability is large, at higher temperature or moisture when existing, easily minute parse, be limited in industrial application; The easy moisture absorption of tetramethylolmethane makes the use of goods impaired; Organic cyanamide class material decomposes is NH
3, N
2, NO
2Etc. nontoxic rare gas element, has the effect of heat absorption, cooling and dilution oxygen.
Patent CN1597747A discloses a kind of nitrogen-phosphorus fire retardant, has used ammonium polyphosphate to do acid source, and tetramethylolmethane is done retardant synergist, and hydrolysis and resistance to elevated temperatures are relatively poor, easily separate out; The APP that US Patent No. 5599626A grinds, pulverizes by the coating of heating trimeric cyanamide improves water absorbability, the easy decomposability of being heated, but the modified technique energy consumption is high, and effect also is difficult to ensure; European patent EP 627462A discloses the fire retardant that a kind of melamine applies ammonium polyphosphate; WO9207902A ionic surface active agent ammonium polyphosphate modifying; The silicone-modified ammonium polyphosphate of WO9208758A to improve the water tolerance of fire retardant, still can not reach good water-fast effect and flame retardant effect.
Although laying the multi-storied garage of flame-retardant cushion can address the above problem, but because vehicle exhaust contains a large amount of hydrogen sulfide, long-term accumulated is easily corroded rubber cushion, reduces work-ing life, therefore, the hydrogen sulfide corrosion-resistant that how to improve rubber cushion is also research emphasis of the present invention.
Summary of the invention
The present invention is directed to the problem that above-mentioned prior art exists, a kind of multi-storied garage is provided, this multi-storied garage is laid the flame-retardant cushion of hydrogen sulfide corrosion-resistant, is achieved by the following technical solutions.
A kind of multi-storied garage, lay the flame-retardant cushion of hydrogen sulfide corrosion-resistant, this rubber cushion is with the material of main part that is combined as of chloroprene rubber, natural rubber and acrylic elastomer, take carbon black as reinforcing filler, take the environment-friendly type phosphor nitrogen combustion inhibitor as fire retardant, take resin as flow ability modifying agent, add the hole-blocking agent hydrogen sulfide corrosion resistant, its composition in weight part, comprising:
Chloroprene rubber 40-50
Natural rubber 30-40
Acrylic elastomer 10-30
Waste-tyre rubber-powder 40-60
Activator 3-6
Stearate 1-2
Anti-aging agent 1-4
Carbon black 25-80
Sulphur 2-3
Flow ability modifying agent 2-4
Environment-friendly type phosphor nitrogen combustion inhibitor 8-10
Hole-blocking agent 3-8
Described environment-friendly type phosphor nitrogen combustion inhibitor is by acid source 0.5-2 part, source of the gas 2-5 part, and carbon source 0.5-4 part and Synergist S-421 95 5-15 part thereof form, and wherein umber used is weight part.
Acid source is: without phosphorus flame retardant and the composition thereof of separating out, and as red phosphorus, phosphoric acid ester TPP, two (diphenyl phosphate) BDP of dihydroxyphenyl propane, Resorcinol (diphenyl phosphoester) RDP, phosphite etc.
Source of the gas is: nitrogenated flame retardant and composition thereof, and as trimeric cyanamide, cyanuric acid, MCA etc.
Carbon source is: water-absorbent is low, becomes high resin and the composition thereof of carbon, as resol, and urea-formaldehyde resin, epoxy resin, PC, fire retardation PC, PAN, carbon fiber, PPO, PA, PVC, PPS, PEEK, polysulfones etc.
Synergist S-421 95 is: have material or the inert filler of catalytic activation effect, and as calcium carbonate, talcum powder, magnesium oxide, zinc oxide, ferric oxide, kaolin, polynite, wollastonite, hydrotalcite, weisspiessglanz, zinc borate, magnesium hydroxide, aluminium hydroxide, mica powder etc.
Wherein chloroprene rubber has good oil resistant, flame retardant properties, and the natural rubber best rubber that is over-all properties, can make up the poor weakness of chloroprene rubber winter hardiness, and acrylic elastomer has high polarity and fully saturated, therefore have excellent oil resistant and high-temperature oxidation, can at high temperature use for a long time.Acrylic elastomer is because the difference of mooney viscosity can be divided into two kinds of high Mooney and low Mooneys, low Mooney is conducive to processing, and high Mooney is conducive to improve performance, for comprehensive its advantage, can adopt acrylic elastomer and the use of high Mooney and low mooney viscosity, ratio for example can be 2:3 ~ 3:2.
The present invention adopts hard (carbon) black N220, N330 and N550 as strongthener, all has corrosion resistance nature preferably, in order to regulate the hardness of product, also can regulate the consumption of carbon black, to meet the different needs.
The problem that can descend in order to solve rubber mobility that carbon black loading too much causes, the present invention has added flow ability modifying agent, for a kind of of coumarone indene resin, phthalic ester or and use, improve the mobility of rubber unvulcanizate.In the present invention take zinc oxide and/or magnesium oxide as activator.
For preventing the corrosion of hydrogen sulfide, add the oxide compound hole-blocking agent, as nickel oxide or chromic oxide, it can generate sulfide with the hydrogen sulfide reaction, sulfide has lower density, can block due to the hole that produces after hydrogen sulfide corrosion, improves the ability of the hydrogen sulfide corrosion-resistant of rubber.The optimum amount of hole-blocking agent is 3-8 part, if consumption is too low, the shutoff hole number is less, anti-sulphur DeGrain; The excessive original performance that affects cross-linked rubber of consumption has limited the range of application of cross-linked rubber.
