The invention belongs to Process Technology of Polymer technical field, specially a kind of be applied to the transparent polypropylene resin manufacturing pen core oil pipe with expressing technique, this acrylic resin is compositionss, and it passes through weight ratio for 100：(0.03～2)：The resin binder of (0.02～0.12), clarifier and dispersant melting mixing obtain；Wherein：Described clarifier is nucleator in organic phosphate class or the mixture for nucleator in organic phosphate class and glucitols transparent nucleator, and described dispersant is the mixture of calcium stearate and monoglyceride.The beneficial effects of the present invention is：The fisheye (or white point) of the transparent polypropylene resin that the present invention obtains is significantly improved, and is particularly suited for extruding pen core oil pipe technique processed.
Description
Technical field
The present invention relates to a kind of acrylic resin, it is exclusively used in manufacturing the transparent polypropylene resin of pen core oil pipe particularly to a kind of.
Background technology
At present, the manufacture raw material of pen core oil pipe all adopts transparent polypropylene resin substantially, and it adds clarifier in granulation process by the Propylene-ethylene random copolymer that a kind of ethylene contents are less than 5wt% (percentage by weight) and makes.Such acrylic resin has preferable intensity, toughness and transparency.The manufacture process of pen core oil pipe mostly adopts expressing technique, easy to operate succinct, the production efficiency height of this manufacturing process.
In prior art, traditional transparent polypropylene resin is typically adopted to manufacture pen core oil pipe, the general pears alcohols transparent nucleator adding no less than 0.2wt% of this resin, because addition is more, its dispersibility in acrylic resin is poor, do not have suitable dispersant to improve the compatibility of itself and acrylic resin again, clarifier agglomeration therefore easily occurs.This traditional transparent polypropylene resin is applied to injection mo(u)lding, and it manufactures during plastic because using Shooting Technique, product is generally thicker, therefore generally fisheye (or white point) phenomenon does not occur in addition.And use above-mentioned traditional transparent polypropylene resin by extruding-out process manufacture pen core oil pipe when, due to product generally relatively thin, therefore it is susceptible to clarifier to reunite, produce the defect of fisheye (or white point), make pen core oil pipe surface that surface indentation occurs, and then after its surface is printed, bite phenomenon occurs, leads to pen core finished product unqualified.
Content of the invention
The invention provides a kind of be applied to the transparent polypropylene resin manufacturing pen core oil pipe with expressing technique, its technical problem to be solved is by targetedly being adjusted to clarifier and dispersant formulation, improve and solve fisheye (or white point) problem, with the defect overcoming prior art to exist.
The following is the specific technical scheme of the present invention.
A kind of be applied to the transparent polypropylene resin manufacturing pen core oil pipe with expressing technique, this acrylic resin is compositionss, and it passes through weight ratio for 100：(0.03～2)：The resin binder of (0.02～0.12), clarifier and dispersant melting mixing obtain；Wherein：Described resin binder is propylene and ethylene atactic copolymer, and its ethylene contents is 0.5～5wt%；The melt temperature of resin binder is 140～165 DEG C, and melt flow rate (MFR) is 3.0～15.0g/10min；Described clarifier is nucleator in organic phosphate class or the mixture for nucleator in organic phosphate class and glucitols transparent nucleator, and in described clarifier, the weight of nucleator in organic phosphate class and glucitols transparent nucleator nucleator in organic phosphate class ratio is for 1: (0～3)；Described dispersant is weight ratio for 1: the calcium stearate of (0.5～1.2) and the mixture of monoglyceride.
Above-mentioned nucleator in organic phosphate class is selected from double one of [2,2 '-methylene-bis- (4,6- di-tert-butyl-phenyl) phosphoric acid] hydroxy Al or 2,2 '-methylene-bis- (4,6- di-tert-butyl-phenyl) sodium phosphate or two kinds；Described glucitols transparent nucleator is three (3,4- dimethyl diphenyl methylene) Sorbitol.
The melt flow rate (MFR) of above-mentioned resin binder is 4～12g/10min.
In above-mentioned clarifier, the weight of nucleator in organic phosphate class and glucitols transparent nucleator is than for 1: (0～2).
The present invention is through substantial amounts of screening experiment, have selected one kind and preferably compound clarifier and dispersant, nucleator in organic phosphate class particularly therein, in the prior art itself and be not exclusively suitable for manufacture pen core oil pipe transparent polypropylene resin, but it is applied to the transparent polypropylene resin manufacturing for pen core oil pipe in the present invention, the fisheye (or white point) of resin is significantly improved, and is therefore particularly suited for extruding pen core oil pipe technique processed.
Specific embodiment
Below will the invention will be further described by specific embodiment, the adjustment or the improvement that it is critical only that clarifier and dispersant due to the present invention, the difference of other parts and prior art no essence, therefore embodiment will focus on enumerating of clarifier and dispersant and its proportioning.
【Embodiment 1～6】
Acrylic resin is compositionss, and component includes resin binder, clarifier and dispersant, forms through melting mixing.Wherein resin binder is propylene and ethylene atactic copolymer, and its ethylene contents is 2～4wt%；The melt temperature of self-made resin base material is 140～160 DEG C, and melt flow rate (MFR) is 3.0～9.0g/10min (according to ASTM D1238 standard testing).
Clarifier is nucleator in organic phosphate class or the mixture of nucleator in organic phosphate class and glucitols transparent nucleator, dispersant is the mixture of calcium stearate and monoglyceride, the specific clarifier of each embodiment and dispersant proportioning is shown in Table 1, resin binder and clarifier and the proportioning of dispersant total amount is shown in Table 2.
【Comparative example 1～2】
Using glucitols transparent nucleator, dispersant calcium stearate or hydrogenation Pulvis Talci, remaining is with embodiment 1～6.
The acrylic resin of each embodiment and comparative example is carried out extrusion and manufactures pen core oil pipe, observe fisheye, the results are shown in Table 3.The turbidity of the acrylic resin of each embodiment and comparative example is shown in Table 3.(turbidity：2mm heavy-gauge sheeting presses GB/T2410-2008 standard testing, fisheye on transmissometer：Detect by an unaided eye under light pen core oil pipe)
