Specific embodiment
The present invention is described in further detail With reference to embodiment.
A kind of preparation method of polypropylene plastics particle, the polypropylene plastics particle include following composition by weight：PP：50
Part, polylactic acid：4-6 parts, α-cyanacrylate：3-5 parts, n-vinyl pyrrolidone：3-5 parts, cyclodextrin：2-4 parts,
Plasticizer：15-25 parts, stabilizer：2-3.5 part, anti-impact modifier：6-8 parts, lubricant：5-10 parts, electrical grade clay：3-5
Part, 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 matching
The basic tree cosmetics of side.Plasticizer can control PP hardnesses, 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 that 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）It is prepared using emulsion grafting polymerization method.The resin has typical on submicro-morphological
Nucleocapsid structure, core are the rubber phase globose nucleus of an a diameter of 10~100nm, and outside is styrene and methyl methacrylate
The shell of ester composition.Due to methyl methacrylate and polypropylene（PP）Solubility parameter it is close, in PP resins and rubber particles
Between play the role of interface bonding agent, formed homogeneous being processed in mixing process with PP, rubber phase is then distributed in particle state
In PP continuous medias, island structure is presented, this special construction imparts the excellent shock resistance of product.When being added in PP
During MBS resins, the impact strength of product can be made to improve 4~15 times, while can also improve the cold resistance of product and processing flowing
Property, and the original optical property of PP resins can be kept.Lubricant can increase the mobility and lubricity of PP, profit of the invention
Lubrication prescription uses paraffin oil and paraffin composition by weight ratio as 1：2 mixture, 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 carry in this way material processing production effect
Rate reduces 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,
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
It is 1 to measure component ratio:2 mixture, antimony oxide burning initial stage, can melt first, material surface formed protective film
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, so as to play fire retardation, magnesium hydroxide has better smoke suppressing effect, hydrogen compared with similar inorganic combustion inhibitor
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 cause material
It can also make material that there is good weatherability on the basis of coloring.
When making, it is preferable that by 50 kilograms of PP, 4 kilograms of polylactic acid, 3 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
