Specific embodiment
Invention is further described in detail With reference to embodiment.
A kind of preparation method of polypropylene plastics particle, the polypropylene plastics particle include following composition by weight: PP:55
Part, polylactic acid: 5-6 parts, α-cyanacrylate: 4-5 part, n-vinyl pyrrolidone: 2-5 parts, cyclodextrin: 2-5 parts,
Plasticizer: 15-25 parts, stabilizer: 2-3.5 parts, anti-impact modifier: 5-8 parts, lubricant: 6-10 parts, electrical grade clay: 3-4
Part, fire retardant: 4-7 part, carbon black: 0.5-1 parts, PP is the basic material of plastic pellet, and the present invention selects SG-1 type PP as matching
The basic tree cosmetics of side.Plasticizer can control PP hardness, increase gloss, and plasticizer of the invention uses phthalic acid
Ester.Stabilizer makes PP have stability, it can slow down reaction, keeps chemical balance, reduces surface tension, prevents light, heat
The effects of decomposition or oxygenolysis, stabilizer of the invention use tri-thiol 2-ethyl hexyl ethanoate antimony, have outstanding initial stage form and aspect
With form and aspect retentivity, thermal stability is superior, and nontoxic, has adapted to the requirement of modern society's environmental protection.Anti-impact modifier makes PP
With shock resistance, anti-impact modifier of the invention uses one styrol copolymer of metacrylate-butadiene, methyl
One styrol copolymer of acrylate-butadiene, that is, MBS is a kind of novel high polymer material, by methyl methacrylate (M), fourth
Diene (B) and styrene (S) are prepared using emulsion grafting polymerization method.The resin has typical on submicro-morphological
Nucleocapsid structure, core are the rubber phase globose nucleus that a diameter is 10~100nm, and outside is styrene and methyl methacrylate
The shell of ester composition.Since methyl methacrylate is close with the solubility parameter of polypropylene (PP), in PP resin and rubber particles
Between play the role of interface bonding agent, with formed homogeneous in PP processing mixing process, rubber phase is then distributed in particle state
In PP continuous media, island structure is presented, this special construction imparts the excellent shock resistance of product.When being added in PP
When MBS resin, the impact strength of product can be made to improve 4~15 times, while can also improve the cold resistance and processing flowing of product
Property, and it is able to maintain the original optical property of PP resin.Lubricant can increase the mobility and lubricity of PP, profit of the invention
Lubrication prescription uses paraffin oil and paraffin composition by weight ratio for the mixture of 1:2, and paraffin oil and paraffin are all good lubricants, together
When or a kind of softening agent, viscosity can be reduced, convenient for material process, can not only mention in this way material processing production effect
Rate reduces production cost, while also making the chemical-resistant resistance ability of material more excellent, when the ratio of the two is 1:2,
Its effect maximizes.Fire retardant makes PP have flame retardant property, and fire retardant of the invention is using antimony oxide and magnesium hydroxide weight
The mixture that component ratio is 1:2 is measured, antimony oxide can melt first at burning initial stage, form protective film on the surface of the material
Completely cut off air, ignition temperature is reduced by the internal endothermic reaction, antimony oxide is gasified at high operating temperatures, dilutes air
Middle oxygen concentration, to play fire retardation, magnesium hydroxide has better smoke suppressing effect, hydrogen compared with similar inorganic fire retardants
Equal unharmful substance discharge in magnesia reproduction, use and waste procedures, and the acid generated in combustion process can also be neutralized
Property and corrosive gas.Carbon black is while being a kind of colorant or good UV resistant agent, addition carbon black make material
It can also make material that there is good weatherability on the basis of coloring.
In production, it is preferable that by 55 kilograms of PP, 5 kilograms of polylactic acid, 4 kilograms of α-cyanacrylate, 4
Kilogram n-vinyl pyrrolidone, 2 kilograms of cyclodextrin, 15 kilograms of phthalic acid ester, 2 kilograms of tri-thiol acetic acid are different pungent
Ester antimony, 5 kilograms of one styrol copolymer of metacrylate-butadiene, 2 kilograms of paraffin oil, 4 kilograms of paraffin, 3 kilograms
Electrical grade clay, 2 kilograms of antimony oxide, 4 kilograms of flame retardant of magnesium hydroxide, 1 kilogram of carbon black be added to the mixer
It is mixed evenly, mixing temperature is 120-140 DEG C, and incorporation time is 20-30 minutes, after mixing, is transferred to cooling and stirs
It mixes and is stirred at low speed in machine 5-10 minutes, finally enter double-screw extruding pelletizing machine and be plasticized at 140-150 DEG C with pelletizing up to institute
State polypropylene plastics particle.Preparation method of the invention is easy easily to be implemented, and large-scale industrial production, and this hair are suitable for
