Description
Technical field
The invention belongs to individual protection equipment smoke mask field, be specially fire-retardant corrosion-resistant gas mask canister plinth POM plastic formula and preparation method.
Background technology
Polyoxymethylene (POM) is a kind of engineering plastics of excellent property, belongs to the simple linear polymer of high-density, high crystalline, is widely used in the fields such as electronic apparatus, machinery, instrument, automobile.In individual respiratory protection equipment field, the existing POM material plastic part that uses of the plastic component as smoke mask obtains example, but polyoxymethylene is that it is an easy firing material, also can burn even under fire-retardant condition containing oxygen superpolymer.But fire-retardant polyoxymethylene does not also have manufacturer production at home, the plastics that market adopts are based on common POM, and flame retardant resistance is poor, are never well solved.
Summary of the invention
Object of the present invention will solve the problem of the poor fire of the POM used such as existing face shield tank joint, by polyoxymethylene modified, overall flame is improved to the modification of POM plastic part, to reach V0 level flame retardant properties, the excellent properties making tank joint strong demoulding plastic component have fire-retardant, anti-capsaicine (OC) to corrode.
The present invention adopts following technical scheme to realize:
A fire-retardant corrosion-resistant gas mask canister plinth POM plastic formula, is made up of the component of following weight part:
POM plastic and 100 parts, PA66 plastics, modified Teflon (PIFE) 2 ~ 5 parts, ammonium polyphosphate (APP) 35 ~ 45 parts, pentaerythrite diphosphate ester melamine salt (MPP) 12 ~ 20 parts, 5 parts, resol, (Chinese is 2 to antioxidant 2246,2'-methylene-bis-(4-methyl-6-tert-butylphenol)) 1 part, Polyurethane Thermoplastic Elastomer rubber (TPU) 10 ~ 15 parts, trimeric cyanamide 10 ~ 15 parts, colour batch 0.1 ~ 1.0 part.
Preferably, be made up of the component of following weight part:
POM plastic 85 ~ 90 parts, 10 ~ 15 parts, PA66 plastics, modified Teflon (emulsion form) PIFE 2 ~ 3 parts, ammonium polyphosphate APP 35 ~ 40 parts, pentaerythrite diphosphate ester melamine salt MPP 12 ~ 16 parts, 5 parts, resol, antioxidant 2246 1 part, Polyurethane Thermoplastic Elastomer rubber TPU 10-12 part, trimeric cyanamide 10-12 part, colour batch 0.5-1.0 part.
The preparation method of above-mentioned flame retardant type corrosion-resistant gas mask canister plinth is as follows:
(1) POM plastic, PA66 plastics, PIFE, APP, MPP, resol, antioxidant 2246, TPU, trimeric cyanamide and colour batch, is taken by weight.
(2), APP, MPP, TPU are mixed after, successively through mixing of heating, plastify, extrude, granulation, mixing obtains flame-retardant master batch.
(3) PIFE is joined in the compound of POM and PA66, obtained modification POM.
(4) obtained flame-retardant master batch and modification POM and trimeric cyanamide, resol, antioxidant 2246 are mixed in proportion, are melt extruded by twin screw, granulation, the obtained modification POM pellet with flame retardant properties, then by pellet injection moulding.
(5), injection moulded products is carried out.Put into charging tray by modification POM pellet, be placed in baking oven and carry out preheating, regulate oven temperature to 80-90 DEG C, take out after preheating 4-6h, stand-by.Wherein, after great many of experiments, determine that oven temperature is to 80-90 DEG C and preheating 4-6h, suitably improve temperature and extend warm up time, being conducive to the raising of the flame retardant properties of fire-retardant POM plastic.
(6), on plastic injection molding machine, gas mask canister plinth is processed.Preheating → reinforced → plasticizing → extrusion moulding (mold temperature 200-220 DEG C) → demoulding → finishing → goods.Wherein, after great many of experiments, determine mold temperature 200-220 DEG C, be conducive to when original mould is constant, process strong demoulding tank plinth goods by fire-retardant POM plastic, and product size is substantially constant.
In order to avoid material decomposes, in resin temperature and barrel, the residence time carries out controlling by regulation: unsuitable long, if during shaping interruption, should reduce barrel temperature.
If when there is overheated phenomenon, should barrel temperature be reduced, replace overheated material with novel material.Because formaldehyde gas can stimulate eyes and throat, people is felt under the weather, during suggestion operation, keep local or overall ventilation.
From raw material angle, when fire-retardant POM plastic (or preparation tank plinth) is burnt, the comprehensive action of its flame-retardant system fire retardant mechanism mainly two or more mechanism of action.Phosphoric acid etc. as fire retardant decomposes can form nonvolatile protective membrane, air-isolation on POM surface, this is isolated mechanism; The simultaneously CO that discharges of fire retardant
2, N
2deng non-flammable gas, diluting inflammable gas concentration, is diluents mechanism; Simultaneously these nonflammable gas occludings supply of oxygen, achieves fire-resistant synergistic and collaborative object, serves the effect suppressing flame, and the polymerization of the free radical produced during polymer combustion, suppression flame interaction can be played, the reaction of terminating chain; Thus effect fire-retardant is significantly produced to POM.
From experimental observation angle, when mask tank plinth carries out combustion test, afterfire lighted by tank plinth, and after leaving flame, afterflame, the time of glowing are not more than 5 seconds.
Test from mask past flame-proof ABS plastic, can flame retardant resistance be met; And carry out the capsaicine of resistance to OC() when testing, parts disconnect, damaged, not resistance to OC corrosion.Select the face shield tank joint that modified flame-retardant POM of the present invention makes, OC class spray (other expose plastic and also spray in the lump) is sprayed at its position, and after placing 24h, the change of observation parts surface, not distortion, burn into damage.
The present invention has following outstanding technical characterstic:
1, flame retardant properties is good, meets the design requirements about flame retardant properties in GB2890-2009, and 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, plastic material nonirritant peculiar smell used, pollution-free, is harmless to the health.
3, process tank joint plastic component and meet product technology requirement, steady quality.
4, resistance to OC corrodibility is excellent.Be sprinkling upon on face shield tank joint by OC spray, after placing 24h, indeformable, damage.
The present invention is reasonable in design, this product can be used for preparing has fire-retardant and face shield tank plinth that the is corrosion-resistant smoke mask cover body of flame retardant type that is corrosion resistant multifunctional, and MF15 gas mask is applied with the plastics pot plinth of modification POM fire retardant material manufacture obtains.
