Description
Technical field
The present invention relates to a kind of modified plastics, more particularly to a kind of flame-retardant modified plastics.
Background technology
In recent years, taken place frequently because fire incident is multiple caused by plastics spontaneous combustion, so country is for family expenses
The plastic material that the aspects such as electrical equipment, office appliance, auto parts machinery are used proposes strict fire protection flame retarding
It is required that, formulate corresponding technical standard and specification.The fire-retardant problem of modified plastics is also increasingly subject to
The concern of people.
Modified plastics, refer on the basis of general-purpose plastics and engineering plastics, by filling, blending,
The processing of the methods such as enhancing, improves the performance of the aspects such as anti-flammability, intensity, impact resistance, toughness
Plastic products.Fire retardant is added by inside common plasticses resin, you can make plastics that there is fire-retardant spy
Property, fire retardant can be the compound system of a kind of or several fire retardants, and other are inorganic fire-retarded
System.
The polypropylene plastics impact resistance and corrosion resistance that generally we commonly use are low, and anti-cracking performance
Difference, heat resistance is poor, therefore largely limits range of application, it is impossible to meet market well
Demand.

The flame-retardant modified plastics of property.
(2) technical scheme
In order to solve the above technical problems, the present invention provides a kind of flame-retardant modified plastics, by following component group
Into：Including polypropylene 40-50 parts, high density polyethylene (HDPE) 4-6 parts, thermoplastic styrene butadiene rubber 15-20
Part, plasticizer 4-8 parts, dispersed lubricant 0.5-2 parts, fire-proof flame-retarded agent 2-4 parts and inorganic fire-retarded association
1-2 parts of agent of effect.
Further, as preferred technical scheme, the flame-retardant modified plastics, by following component group
Into：Including 45 parts of polypropylene, 5 parts of high density polyethylene (HDPE), 18 parts of thermoplastic styrene butadiene rubber, plasticising
1 part of 5 parts of agent, 0.5 part of dispersed lubricant, 2 parts of fire-proof flame-retarded agent and inorganic fire-retarded synergist.
Further, the dispersed lubricant is glyceryl monostearate, ethylene bis stearamide, low
Molecular weight ionomer and ethylene-vinyl acetate copolymer mix.
Further, the inorganic fire-retarded synergist is in talcum powder, Firebrake ZB, wollastonite and mica
Any one or two or more combinations.
Further, the preparation method of the flame-retardant modified plastics is：Each material is proportionally first weighed,
Then whole materials is added into homogenizer is carried out high-speed stirred 5-10 minutes, will be mixed
Material is added to the main feeder of extruder, and material is put into double screw extruder by main feeder
Middle extruding pelletization, the processing temperature of double screw extruder is respectively：160℃±10℃、180℃±10℃、
200℃±10℃、205℃±10℃、220℃±10℃、240℃±10℃、255℃±10℃、

By water-cooled, pelletizing and drying after material extrusion, described flame-retardant modified plastics are prepared.
(3) beneficial effect
The present invention is helped with polypropylene as matrix by adding fire retardant, lubricant and special processing
Combination between agent, so as to prepare the modified plastics with anti-flammability.Not only anti-cracking performance is strong,
And corrosion resistance is also fine, it is important to be able to fire protection flame retarding, polypropylene plastics impact resistance is overcome
Property and corrosion resistance are low, splitting resistance, the shortcoming of poor heat resistance, low production cost, with extensive
Application prospect.
