Description
Technical field
The invention belongs to individual protection equipment canister respirator field, the most fire-retardant corrosion-resistant gas mask canister plinth
POM plastic formula and preparation method.
Background technology
Polyformaldehyde (POM) is the engineering plastics of a kind of function admirable, belongs to high density, the linear polymer of high crystalline, extensively
General it is applied to the fields such as electronic apparatus, machinery, instrument, automobile.Individual respiratory protection equipment field, moulding as canister respirator
Materials and parts have used POM material plastic part to obtain example, but polyformaldehyde is oxygen-containing high polymer, and it is an easy firing material, very
Can also burn as under the conditions of fire-retardant.But, fire-retardant polyformaldehyde does not the most also have manufacturer production, and what market used moulds
Material is based on common POM, and anti-flammability is poor, is never well solved.
Summary of the invention
The purpose of the present invention to solve the problem of the poor fire of the POM used such as existing face shield tank joint, passes through polyformaldehyde
Modification, improves overall flame to POM plastic part modification, to reach V0 level fire resistance, makes tank joint strong demoulding working of plastics have
There is the excellent properties that capsaicin (OC) fire-retardant, anti-is corroded.
The present invention adopts the following technical scheme that realization:
A kind of fire-retardant corrosion-resistant gas mask canister plinth POM plastic formula, is made up of the component of following weight portion:
POM plastic and 100 parts of PA66 plastics, modified Teflon (PIFE) 2～5 parts, APP (APP) 35
～45 parts, pentaerythrite diphosphate ester melamine salt (MPP) 12～20 parts, 5 parts of phenolic resin, antioxidant 2246 (Chinese
Title is 2,2'-di-2-ethylhexylphosphine oxide-(4-methyl-6-tert-butylphenol)) 1 part, Polyurethane Thermoplastic Elastomer rubber (TPU) 10
～15 parts, tripolycyanamide 10～15 parts, color masterbatch 0.1～1.0 parts.
Preferably, it is made up of the component of following weight portion:
POM plastic 85～90 parts, PA66 plastics 10～15 parts, modified Teflon (emulsion form) PIFE 2～3 parts, poly-
Ammonium phosphate APP 35～40 parts, pentaerythrite diphosphate ester melamine salt MPP 12～16 parts, 5 parts of phenolic resin, antioxidant
2246 1 parts, Polyurethane Thermoplastic Elastomer rubber TPU 10-12 part, tripolycyanamide 10-12 part, color masterbatch 0.5-1.0 part.
The preparation method of above-mentioned flame retardant type corrosion-resistant gas mask canister plinth is as follows:
(1), weigh by weight POM plastic, PA66 plastics, PIFE, APP, MPP, phenolic resin, antioxidant 2246,
TPU, tripolycyanamide and color masterbatch.
(2), by after APP, MPP, TPU mix homogeneously, sequentially pass through mixing of heating, plastify, extrude, pelletize, be mixed to prepare
Flame-retardant master batch.
(3) PIFE is joined in the compound of POM Yu PA66, prepare modified POM.
(4) prepared flame-retardant master batch is mixed in proportion with modified POM and tripolycyanamide, phenolic resin, antioxidant 2246,
Melt extruded by twin screw, pelletize, prepare and there is the modified POM pellet of fire resistance, then pellet is molded.
(5), injection moulded products is carried out.Charging tray will be put into by modified POM pellet, be placed in baking oven and preheat,
Regulation oven temperature, to 80-90 DEG C, takes out after preheating 4-6h, stand-by.Wherein, after great many of experiments, oven temperature is determined extremely
80-90 DEG C and preheating 4-6h, properly increase temperature and extend preheating time, the raising of the fire resistance of the most fire-retardant POM plastic.
(6), on plastic injection molding machine, gas mask canister plinth is processed.Preheating → charging → plasticizing → extrusion molding
(forming temperature 200-220 DEG C) → demoulding → finishing → goods.Wherein, after great many of experiments, forming temperature 200-220 is determined
DEG C, be conducive in the case of original mould is constant, with the fire-retardant POM plastic strong demoulding tank plinth goods of processing, and product chi
Very little it is basically unchanged.
In order to avoid material is decomposed, in resin temperature and barrel, the holdup time carries out by regulation control: unsuitable long,
If molding is interrupted, barrel temperature should be reduced.
If it occur that during overheated phenomenon, barrel temperature should be reduced, with the overheated material of new material displacement.Due to formaldehyde gas
Know from experience and stimulate eyes and throat, make people feel under the weather, it is proposed that keep during operation partly or wholly ventilating.
For raw material angle, during fire-retardant POM plastic (or preparation tank plinth) burning, its flame-retardant system fire retardant mechanism master
If the comprehensive function of the two or more mechanisms of action.Phosphoric acid etc. such as fire retardant decomposes can be formed non-volatile on POM surface
Protecting film, air-isolation, this be isolation mechanism；The CO that fire retardant discharges simultaneously2、N2Deng non-flammable compressive gas, dilute combustibility
Gas concentration, is diluents mechanism；These nonflammable gas occludings supply of oxygen simultaneously, it is achieved that fire-resistant synergistic and collaborative
Purpose, serves the effect of suppression flame, and the polymerization of free radical produced during polymer combustion, suppression flame can be played and make
With, the reaction of terminating chain；Thus POM is produced the most fire-retardant effect.
From experimental observation angle, when mask tank plinth carries out combustion test, tank plinth is lighted after-combustion, is left flame
After, afterflame, the time of glowing are not more than 5 seconds.
It was tested with flame-proof ABS plastic from the mask past, anti-flammability can be met；And carry out the capsaicin of resistance to OC() test time,
Parts disconnect, breakage, are weak to OC corrosion.Selecting the face shield tank joint that the modified flame-retardant POM of the present invention makes, OC is sprayed at its position
Class spray (other expose plastic and spray the most in the lump), after placing 24h, observation parts surface change, not deformation, burn into damage.
The present invention has a technical characterstic highlighted below:
1, fire resistance is good, meets the design requirement about fire resistance in GB2890-2009, and test face shield leaves flame
After, sustained combustion is less than 5 seconds.Combustibility can reach EN136-2004 EU criteria requirement.
2, plastic material nonirritant abnormal flavour used, pollution-free, is harmless to the health.
3, processing tank joint working of plastics meets product technology requirement, steady quality.
4, resistance to OC corrosivity is excellent.Will be sprinkling upon on face shield tank joint by OC spray, after placing 24h, indeformable, damage.
The present invention is reasonable in design, and this product can be used to prepare that to have fire-retardant and corrosion resistant multifunctional flame retardant type corrosion-resistant
The face shield tank plinth of canister respirator cover body, the plastic tank joint manufactured with modified POM fire proofing on MF15 gas mask
Popularization and application have been obtained on Zuo.
