Specific embodiment
The present invention is described in further detail With reference to embodiment.
A kind of formula of polypropylene plastics particle, the polypropylene plastics particle include following composition by weight：PP：50 parts, it is poly-
Lactic acid：4-6 parts, α-cyanacrylate：3-5 parts, n-vinyl pyrrolidone：3-5 parts, cyclodextrin：2-4 parts, plasticising
Agent：15-25 parts, stabilizer：2-3.5 part, anti-impact modifier：6-8 parts, lubricant：5-10 parts, electrical grade clay：3-5 parts,
Fire retardant：5-7 parts, carbon black：0.5-1 parts.PP is the basic material of plastic pellet, and the present invention selects SG-1 types PP as formula
Basic tree cosmetics.Plasticizer can control PP hardnesses, increase gloss, and plasticizer of the invention uses phthalic acid ester.Surely
Determining agent makes PP have stability, it can slow down reaction, keeps chemical balance, reduces surface tension, prevent light, thermally decompose or
The effects that oxygenolysis, stabilizer of the invention use tri-thiol 2-ethyl hexyl ethanoate antimony, have outstanding initial stage form and aspect and form and aspect
Retentivity, thermal stability is superior, and nontoxic, has adapted to the requirement of modern society's environmental protection.It is anti-that anti-impact modifier has PP
Impact property, anti-impact modifier of the invention use one styrol copolymer of metacrylate-butadiene, methacrylic acid
Ester-one styrol copolymer of butadiene, that is, MBS is a kind of novel high polymer material, by methyl methacrylate（M）, butadiene
（B）And styrene（S）It is prepared using emulsion grafting polymerization method.The resin has typical core-shell structure copolymer on submicro-morphological
Structure, core are the rubber phase globose nucleus of an a diameter of 10~100nm, and outside is styrene and methyl methacrylate composition
Shell.Due to methyl methacrylate and polypropylene（PP）Solubility parameter it is close, played between PP resins and rubber particles
The effect of interface bonding agent is formed homogeneously being processed in mixing process with PP, and it is continuous that rubber phase is then distributed in PP with particle state
In medium, island structure is presented, this special construction imparts the excellent shock resistance of product.When addition MBS resins in PP
When, the impact strength of product can be made to improve 4~15 times, while can also improve the cold resistance and processing fluidity of product, and energy
Enough keep the original optical property of PP resins.Lubricant can increase the mobility and lubricity of production, and lubricant of the invention is adopted
It is 1 with paraffin oil and paraffin composition by weight ratio：2 mixture, paraffin oil and paraffin are all good lubricants, while still
A kind of softening agent can reduce viscosity, be processed convenient for material, can not only put forward the production efficiency of material processing in this way, reduce
Production cost, while also so that the chemical-resistant resistance ability of material is more excellent, when the ratio of the two is 1:When 2, effect
It maximizes.Fire retardant makes PP have flame retardant property, and fire retardant of the invention is using antimony oxide and magnesium hydroxide composition by weight
Ratio is 1:2 mixture, antimony oxide can be melted, it is empty to form protective film isolation in material surface first at burning initial stage
Gas reduces ignition temperature by the internal endothermic reaction, and antimony oxide is gasified at high operating temperatures, and it is dense to dilute oxygen in air
Degree, so as to play fire retardation, magnesium hydroxide has better smoke suppressing effect, magnesium hydroxide compared with similar inorganic combustion inhibitor
Equal unharmful substance discharge in reproduction, use and waste procedures, and the acidity generated in combustion process and corruption can also be neutralized
Corrosion gas.Carbon black is while being a kind of colorant or good UV resistant agent, addition carbon black cause material colouring
On the basis of can also make material have good weatherability.
When making, by 50 kilograms of PP, 4 kilograms of polylactic acid, 3 kilograms of α-cyanacrylate, 4 kilograms of N-
Vinyl pyrrolidone, 2 kilograms of cyclodextrin, 15 kilograms of phthalic acid ester, 2 kilograms of tri-thiol 2-ethyl hexyl ethanoate antimony, 5
Kilogram one styrol copolymer of metacrylate-butadiene, 2 kilograms of paraffin oil, 4 kilograms of paraffin, 2 kilograms electrical
Grade clay, 2 kilograms of antimony oxide, 4 kilograms of flame retardant of magnesium hydroxide, 1 kilogram of carbon black are added in mixing machine to mix and be stirred
It mixes uniformly, mixing temperature is 120-140 DEG C, and incorporation time is 15-20 minutes, after mixing, is transferred in cooling and stirring machine
Stirring at low speed 5-8 minutes finally enters double-screw extruding pelletizing machine and is plasticized at 140-150 DEG C with pelletizing up to the polypropylene
Plastic pellet.The plastic pellet that is obtained of the present invention has excellent insulating properties, physical mechanical property, elasticity, resistance to ag(e)ing, resistance to
Corrosivity, anti-flammability, weatherability etc., cheap, high yield rate, function admirable, environmental protection.
