Abstract
FIELD OF THE INVENTION: the present invention is the processing and the application thereof of macromolecular material
The present invention adopts the method for adding composite nucleating agent and makes the commodity polypropylene bring out polypropylene material based on beta crystal, and used composite nucleating agent is applicable to the homo-polypropylene of various grades.This kind material and copolymerized type propene polymer can reach the performance of copolymerized type propene polymer with the mechanical property of the blend of 1: 1 ratio, thereby can be used for making extruding pipe material and moulding, thereby can reduce the consumption of Co-polypropylene and the cost of goods.
Description
FIELD OF THE INVENTION: the present invention is the processing and the application thereof of macromolecular material
The prior art present situation: isotatic polypropylene is the polymorphic resin material, and known crystal formation mainly contains three kinds, oblique crystal (α type), hexagonal crystalline substance (β type) and three tiltedly brilliant (γ types).Alpha-crystal form is the most stable on thermodynamics, so mainly contains the crystallization of α type in the commodity polypropylene, and the γ type usually just can be observed during crystallization under high pressure and in the test of sharply degraded.
Beta crystal is that triumphant plucked instrument of nineteen fifty-nine (H.D.Keith) and handkerchief pellet (F.J.Padden) are found when the spherocrystal of research alpha-crystal form, further discover, when crystallization condition changed, the crystalline modification that can occur was very complicated, and had found approach for preparing the polypropylene that contains beta crystal.Other scholars' result of study shows that it is main sample that strict temperature control can access beta crystal, and thermograde is big more, helps generating beta crystal more.Induce down at high shear rate in addition, also can generate beta crystal in the isotatic polypropylene.The method of above-described various mutagenesis beta crystals is limited to laboratory scale mostly, so far as yet not relevant for the productive applied research report of Beta-crystalline polyacrylic.
In recent years, utilize polyacrylic changes of crystal, made a kind of product innovation of R type polypropylene biaxially oriented film.The alligatoring face of this film is to obtain by melting condition and the Tc of controlling the commodity acrylic resin, but the control condition of this kind method is very strict, so product percent of pass is lower.
The purpose of invention, content and advantage thereof: the present invention adds the mutagenesis of nucleator isotatic polypropylene to become a kind of method easily of beta crystal, thereby makes the commodity polypropylene bring out the beta crystal that obtains high level.
The present invention is by the specific nucleator of blending, thereby obtains the polyacrylic resin material based on beta crystal on industrial installation.
But resin material instead of part copolymerized type propene polymer of the present invention and be used to make polypropylene extruding pipe material and injection-molded item.
Specific nucleator used in the present invention is to be main by the additive pimelic acid, and weighting agent lime carbonate is the auxilliary mixture of forming.It can generally be suitable for making the commodity homo-polypropylene of various grades to form beta crystal.
Among the present invention, the addition of composite nucleating agent is 0.01～0.1 part for 100 parts of (parts by weight) polypropylene, and under this mixing proportion, the beta-crystalline form content of most homo-polypropylene all can reach 60%, reaches as high as 90%.Under identical proportioning, the melt index of homo-polypropylene is more little, and then beta-crystalline form content is high more.Because the formation of beta crystal, the normal temperature of the homo-polypropylene of various grades (23 ℃) notched Izod impact strength all increases, and major part can reach 2.0～2.5 times of former base-material; Heat-drawn wire also shows as the trend of raising simultaneously; Because flexible improves, the static bending intensity of material will correspondingly decrease, but not influence service requirements.
Specific nucleator used in the present invention is to be combined into agent by additive pimelic acid and weighting agent lime carbonate are handled to prepare to be called through certain compounding technology.Used equipment complex is general mixing apparatus.
Be combined into the blending process of mixture and base-material homo-polypropylene, simple possible can be mixed with other auxiliary agent simultaneously in the post-processing stages of acrylic resin production, finishes granulation more in the lump, thereby can carry out large-tonnage production.
The composition of Beta-crystalline polyacrylic goods of the present invention: Beta-crystalline polyacrylic resin material can with copolymerized type propene polymer blending in certain proportion, wherein the blend with 1: 1 ratio can be used for making polypropylene extruding pipe material and polypropylene moulding, product properties all can reach the standard of performance of the made goods of pure copolymerized type propene polymer, and goods factory cost and price all can correspondingly reduce.
Because Beta-crystalline polyacrylic can make mechanical property separately be replenished raising with molten fully the mixing also of copolymerized type propene polymer.Promptly with the blend of ratio blending in 1: 1, the good low-temperature impact resistance of copolymerized type propene polymer was remained unchanged, and can make its normal temperature impact property this kind performance that increases again is not contain the homo-polypropylene of composite nucleating agent and copolymerized type propene polymer is inaccessiable with the blend institute of same ratio blending.
The embodiment of the invention:
One. the present inventor brings out the test of beta crystal simultaneously to face south four homo-polypropylene trade mark SOF, 1300,1400,3702 in the commodity polypropylene that the chemical plant produces of Beijing yanshan petrochemical main office.The mixing proportion of base-material homo-polypropylene and composite nucleating agent is 100: the 0.1(parts by weight), this blend composition fully mixes 3～5 minutes by the high speed blender, and the gained blended stock is through extruding pelletization of plastics extruder; This blending pellet makes bulk specimen by the XS-ZY-125A plastic injection equipment, presses GB1043-79, GB1042-79, HG again
2-1170-77 standard is carried out charpy impact test; Static beaming test, Mechanics Performance Testings such as heat-drawn wire test, the beta-crystalline form content test apparatus is Tianjin, island GS-3B type X-ray diffractometer in the blending pellet spherocrystal, test is calculated according to Jones (Jones) method:
K= (H
