Description
Technical field
The invention belongs to smoke mask cover technical field, be specially flame retardant type corrosion-resistant smoke mask cover body sizing compound formula and preparation method.
Background technology
In individual respiratory protection equipment field, smoke mask is as a kind of self-absorbing filtering type protection product, and cover body used is natural rubber material, when being only subject to the injuries such as contamination air denaturant steam, smog as people, can play the protection to personnel's face respiratory tract; When running into fire and occurring, enclosure portion easily burns, and damages operating personnel.
At present, common smoke mask has helmet-type smoke mask and two kinds, head-type smoke mask on market at home.The rubber that helmet-type and head-type mask face shield adopt is natural rubber is main, and flame retardant resistance is poor, and price is relatively low.In recent years new requirement is proposed to the flame retardant properties of face shield and other technical indicator, adopt natural rubber manufacture can not meet better flame retardant resistance, current research is mainly for solving the fire-retardant of cover body rubber, in order to improve the flame retardant resistance defect of cover body, be necessary to carry out Testing and research to fire-retardant halogenated butyl rubber formula.
Summary of the invention
The object of the invention is to solve the incendive shortcoming of natural rubber, adjusted by material, prepare a kind of good flame resistance and meet face shield technical indicator and the chlorinated butyl sizing compound formula be harmless to the health, to reach V0 level flame retardant properties, make afterflame, the time of glowing is not more than 5 seconds, and there is the excellent properties that anti-capsaicine (OC) corrodes.
The present invention adopts following technical scheme to realize:
A kind of flame retardant type corrosion-resistant smoke mask cover body sizing compound formula, be made up of the component of following weight part: chlorinated butyl rubber (1068) 100 parts, zinc oxide (indirect method) 8-12 part, magnesium oxide 0.3-0.5 part, promotor ZDC 1.5-2.0 part, anti-aging agent 2-3 part, clorafin 0.5-2 part, hard(carbon)black 30-40 part, dioctyl phthalate (DOP) 3-6 part, stearic acid 1.2-2 part.
Preferably, chlorinated butyl rubber (1068) 100 parts, zinc oxide (indirect method) 8-10 part, magnesium oxide 0.3-0.4 part, promotor ZDC 1.5-1.8 part, anti-aging agent 2-2.5 part, clorafin 1 part, hard(carbon)black 35-40 part, dioctyl phthalate (DOP) 3-5 part, stearic acid 1.2-1.5 part.
Indirect process zinc oxide take generally zinc ingot metal as raw material, and zinc is converted to zinc fume in plumbago crucible under the high temperature of 1000%, is generated zinc oxide subsequently, and after cooling tube, collect to obtain Zinc oxide particles by the atmospheric oxidation blasted.Different zinc ingot metal raw materials, the purity zinc oxide produced is also different, and this technique mainly produces the zinc oxide of 99.5%-99.7%.Indirect process zinc oxide operative norm GB/T3185-92, raw material is except zinc ingot metal, and cadmia is also the main production raw material of indirect process zinc oxide.
Analyze from raw material angle, be add clorafin in material of main part at chlorinated butyl rubber, living radical can be caught, under high temperature, halogen containing flame-retardant decomposes generation halogen atom, further reaction generates muriate, can discharge hydrogen chloride gas when burnt, this kind of gas is heavier than air, and easily covering combustionmaterial surface is that burning slows down so that stop and play iris action.When judging rubber flame-retarded performance from combustion test analysis (or with EN136-2004 standard test methods), self-extinguishing head mould measuring rubber is enclosed within by sample product, weighed by two aspects: one is self-extinguishing time, namely sample leaves the time that flame burns away after the burning specified time.Two is combustionvelocities, and the distance of namely prolonging combustion with the unit time judges.
Judge from experimental observation angle, face shield, on ferrule die device, carries out combustion test by test method, face shield with metal head mould horizontally rotates with certain speed, when visor portion observes combustion case through flame, after leaving flame, actual afterflame, the time of glowing are not more than 5 seconds.
The preparation method of above-mentioned flame retardant type corrosion-resistant smoke mask cover body is as follows:
(1) chlorinated butyl rubber (1068), zinc oxide, magnesium oxide, promotor ZDC, clorafin, hard(carbon)black, dioctyl phthalate (DOP), stearic acid, is taken by weight;
(2), on rubber mixing machine, chlorinated butyl rubber is plasticated after, add carbon black, dioctyl phthalate (DOP) is mixing, temperature controls below 55 degree, adds the obtained fire retardant glue of other small powder mixing;
(3), through processing the sizing material meeting technical indicator, through mold pressing injection molding, the qualified cover body product assembled can be obtained.
The present invention has following outstanding technical characterstic:
1, flame retardant properties is good, and more than the design requirements about flame retardant properties in GB2890-2009, after test face shield leaves flame, sustained combustion is no more than 5 seconds.Combustionproperty can reach the requirement of EN136-2004 EU criteria.
2, nontoxic, the nonirritant peculiar smell of mask material used, pollution-free, is harmless to the health.
3, tensile strength high (>=12MPa), elongation large (>=600%), meets technical target of the product requirement, and cover body injection vulcanized quality is stablized.
4, have excellent corrosion resistance nature, excellent high-low temperature resistant adaptability, antitoxin performance is excellent in natural rubber more than 20 times.
The present invention is reasonable in design, and this product has the fire-retardant and corrosion-resistant smoke mask cover body of flame retardant type that is corrosion resistant multifunctional.
