Description
Technical field
The invention discloses a kind of polyacrylic preparation method of flame-retardant smoke inhibition, belong to resin making technique field.
Background technology
A kind of thermoplastic resin of prepared by polypropylene is by propylene polymerization.It is divided into isotactic poly- third by methyl arrangement position
Three kinds of alkene, random polypropylene and syndiotactic polypropylene.
The same side that methyl is arranged in molecular backbone claims isotactic polypropylene, if the chaotic molecular backbone that is arranged in of methyl
Both sides claim random polypropylene, and the both sides that molecular backbone is arranged alternately in when methyl claim syndiotactic polypropylene.
Polypropylene is the highly crystalline polymer of nontoxic, odorless, tasteless milky, is product most light in current all plastics
One of kind.It is particularly stable to water, and the water absorption rate in water is only 0.01%, molecular weight about 80,000~150,000.Good moldability, but because
The big thick article of shrinkage factor is easily recessed, and to the higher part of some dimensional accuracies, is difficult to reach requirement, product surface good luster.
The development of auto industry be unable to do without the process of plasticization of Automobile, and PP, which is used for auto industry, has stronger competitiveness,
But because its modulus and heat resistance are relatively low, impact strength is poor, therefore can not be directly used as auto parts machinery, what is used in car is
MODIFIED PP product, its heat resistance can bring up to 145 DEG C~150 DEG C by 80 DEG C, and can bear not aging after 750~1000h of high temperature,
It is not cracked.The polyacrylic industrial production of China is started from the 1970s, by the development of more than 30 years, has been generally defined
A variety of production technologies such as solvent method, liquid-phase bulk-vapor phase method, batch liquid bulk polymerization, vapor phase method develop simultaneously, large, medium and small production
The production pattern that scale coexists.The large-scale polypropylene production apparatus of China is based on introducing technology, medium-sized and small-sized polypropylene life
Device is produced based on domestic technology.Also in household electrical appliance, plastic pipe, high material, simple tension PP films thoroughly, biaxial tension
PP films can be used for packaging material and capacitor film, MODIFIED PP woven bag etc. to have extensive utilization.
In the acrylic resin of general industry production, isotactic structural content is about 95%, and remaining is a random or rule poly- third
Alkene.Industrial products are using isotactic thing as main component.Polypropylene is also including the copolymer of propylene and a small amount of ethene.Usually partly
Clear, colorless solid is odorless nontoxic.The highly crystallized due to compound with regular structure, therefore fusing point may be up to 167 DEG C.It is heat-resisting, corrosion-resistant,
Product can be its outstanding advantages with moise-heat sterilization.Density is small, is most light general-purpose plastics.Shortcoming is that low-temperature impact resistance is poor, compared with
It is easy to aging, poor flame retardant properties, but can be overcome respectively by modification.
Therefore invent it is a kind of can the fire-retardant and can polypropylene that enough presses down cigarette there is positive effect to resin making technique field.
