Abstract
The invention discloses flame-retardant polypropylene plastic. The flame-retardant polypropylene plastic comprises the following component in parts by weight: 70-80 parts of polypropylene resin, 40-50 parts of a fire retardant, 10-20 parts of terpene resin, 8-12 parts of nano-titania and 0.2-0.8 part of an antioxidant. By adding the fire retardant prepared by mixing ammonium polyphosphate, grafted maleic anhydride and nano-clay into the flame-retardant polypropylene plastic, ammonium polyphosphate and nano-clay in a compound flame-retardant polypropylene system can be uniformly dispersed, so that the flame-retardant efficiency is obviously improved, the crystallization property of a polypropylene matrix can be improved, and the tenacity of a material is improved.
Description
Technical field
The present invention relates to plastic applications, be specifically related to a kind of Polypropylene flame-retardant plastic.
Background technology
Polypropylene (PP) is one of maximum resin of whole world yield, be widely used in packaging,
A lot of industry such as textile, building materials, automobile, electronic/electrical device, office appliance.But it can not
One of shortcoming ignored is its inflammability, fire-retardant for PP, and industrial circle is still to use
The conventional flame retardant such as halogen system, phosphorus system and inorganic hydroxide are main.But owing to some halogen system hinders
Combustion agent produces potential threat to environment, and therefore development environmental protection fire retarding agent is the most important development
Direction.As emerging environmental friendliness flame-retardant system, phosphorus-nitrogen expanding fire retardant becomes fire-retardant
The study hotspot of polypropylene material.Although expansion type flame retardant disclosure satisfy that the requirement of environmental protection, but
There is also a lot of deficiency.Such as flame retarding efficiency few additive is big, with the compatibility of polymeric matrix
Bad, make material mechanical performance significantly decline.Nano clay is compounded with expansion type flame retardant
Use can improve expansion type flame retardant flame retarding efficiency, but in the technical scheme improved, intumescent hinders
The total addition level of combustion agent and nano clay is the most at least the highest 25%, and mechanical property
DeGrain can be improved.
Summary of the invention
It is an object of the invention to overcome defect present in prior art, it is provided that a kind of anti-flammability
Can and the good Polypropylene flame-retardant plastic of mechanical property.
For realizing above-mentioned technique effect, the technical scheme is that a kind of polypropylene fire retardant is moulded
Material, it is characterised in that the composition of described Polypropylene flame-retardant plastic includes: acrylic resin 70～
80 parts, fire retardant 40～50 parts, terpene resin 10～20 parts, nano-titanium oxide 8～12 parts,
Antioxidant 0.2～0.8 part.
Wherein, the composition of described fire retardant and the percentage by weight of each component are: APP
60～75%, grafted maleic anhydride 18～27%, surplus is nano clay, described grafting Malaysia
The percent grafting of anhydride is 1%.
Wherein, described grafted maleic anhydride is copolymerization PP grafted maleic anhydride or homopolymerization PP
Grafted maleic anhydride.
Advantages of the present invention and having the beneficial effects that:
Polypropylene flame-retardant plastic of the present invention is by adding by APP, grafted maleic anhydride and receiving
The fire retardant that rice clay mixes, the APP in polypropylene compounding flame retardant and nanometer
Clay all disperse ratio is more uniform, flame retarding efficiency significantly improves, and can improve polypropylene matrix
Crystal property, thus improve the toughness of material.
