Based on the prior art, the polyolefin composition additionally comprises 10-30 parts of linear low density polyethylene which is then compounded with other components to exert synergistic effect. The prepared polypropylene composition has the advantages of good toughness, low cost, easy forming and the like and is suitable for preparing the fenders.
Description
Technical field
The present invention relates to the modified polypropylene material field, specifically, relate to a kind of fender polypropene composition and technology of preparing thereof of being used for.
Background technology
Domestic automobile splash pan material category is a lot of at present.Be main mainly,, also have the metal of employing to make splash pan in addition like EVA, PU, PP, TPO etc. with plastics.
In the patent of invention of publication number CN2883090; Disclosing and having adopted PU is the splash pan prescription of base-material; In the patent of invention of publication number CN1049479, disclose the splash pan prescription that adopts rubber to add spun glass, these prescriptions all exist cost than shortcomings such as higher, difficult forming.
Summary of the invention
The objective of the invention is to overcome the defective of prior art, provide that a kind of cost is low, the polypropene composition that can be used for preparing fender of good toughness, easy-formation.
Another object of the present invention provides the preparation method of above-mentioned compsn.
To achieve these goals, the present invention adopts following technical scheme:
A kind of polyolefin compositions comprises acrylic resin and linear low density polyethylene.Its concrete prescription is made up of the component of following parts by weight:
Acrylic resin 20-50 part

Lime carbonate 10-30 part.
In the said polyolefins compsn, can also add high density polyethylene(HDPE) 2-10 weight part or POE 2-10 weight part.
In the said polyolefins compsn, said acrylic resin is the COPP resin.Its melt flow rate(MFR) more than or equal to 15g/10min (230 ℃/2.16KG).
In the said polyolefins compsn, said polyethylene wax preferred number average molecular weight is 700-10000g/mol.Polyethylene wax has good wellability, can better combine with filler, and in addition, polyethylene wax also plays the effect of lubricant.
In the said polyolefins compsn, said linear low density polyethylene is molten refer to for 2g/10min (190 ℃/2.16KG).
In the said polyolefins compsn, said high density polyethylene(HDPE) is molten refer to for 8g/10min (190 ℃/2.16KG).
In the said polyolefins compsn, said POE is molten refer to for 1g/10min (190 ℃/2.16KG), the adding of this kind material can improve the toughness of system.
In the said polyolefins compsn, the particle diameter of said lime carbonate is 1000 orders-5000 orders.The main effect of lime carbonate is the toughness of raising system and reduces cost.
Said polyolefins preparation of compositions method comprises the steps:
(1) place mixing machine to mix in acrylic resin, polyethylene wax, linear low density polyethylene, high density polyethylene(HDPE), POE, lime carbonate, the rotating speed of mixing machine is 200 ~ 450 rev/mins, and the time is 3 ~ 8 minutes;
(2) mixture that (1) step is obtained is sent in the screw extrusion press with melting mixing, extruding pelletization, drying under 180 ~ 235 ℃ the temperature thereupon, can obtain polyolefin compositions.
Compared with prior art, the present invention has following beneficial effect:
The present invention on the basis of existing technology; Increased linear low density polyethylene 10-30 part, composite with other components again, the performance synergy; The polypropene composition for preparing has advantages such as good toughness, cost are low, easy-formation, is suitable for preparing fender.
