Abstract
The invention relates to a tackifying polyamide 66 combination, which is made from raw materials of the following percentage by weight: 70 percent to 94.7 percent of nylon 66, 0.1 percent to 35 percent of tackifier, 4 percent to 20 percent of compatilizer, 0.1 percent to 5 percent of nanometer silicon dioxide and 0.1 percent to 1 percent of antioxidant. The invention has the advantages that: the method of making is simple and the impact toughness of the made material is substantially improved while maintaining original excellent properties of nylon 66; the strength of fused mass is high, thereby the fused mass can be extruded or made into various thin-wall shaping articles through blow molding; particularly, due to possessing ideal compliance, high tenacity, low friction coefficient, the material can be used in high performance polymer pipe for surgery.
Description
Technical field
The present invention relates to a kind of tackifying polyamide 66 composition, can be used for extruding or be blow molded into various thin-wall sections, particularly, belong to the engineering plastics technical field because good kindliness, high tenacity, the low-friction coefficient of this material can be used for the used for medical procedures high performance polymers pipes.
Background technology
Nylon 66 has good physics, mechanical property, tensile strength height for example, excellent in abrasion resistance, shock resistance is good, chemical-resistant resistance and oil-proofness are outstanding, are most widely used kinds in the five large-engineering plastics, are widely used in various electronic electric equipments and household appliances.The number-average molecular weight of common widely used nylon 66 very low (＜30000), low like this molecular weight make that melt strength and viscosity are too low and be not suitable for extrusion profile or blow molding, generally can only injection moulding, and this makes its range of application receive very big restriction.The polymkeric substance of extrusion moulding will have suitable melt strength and viscosity, also there are some relevant patents to relate to toughness reinforcing tackify nylon abroad, as: United States Patent (USP), the applying date: 1991.8.27, the patent No.: 5,043,384, patent name: blow-molding nylon resin, add Tackified polymeric such as vinylbenzene and (methyl) acrylic copolymer, the polystyrene of modified rubber, United States Patent (USP) in relative viscosity in less than 100 nylon, the applying date: 1990.10.30, the patent No.: 4,966,941, patent name: the blowing nylon composite, wherein adopt to add be rich in ethene acid anhydrides as toughness reinforcing tackifier and add the method for tetrafluoroethylene as surface treatment agent.But all do not relate to present method.
Summary of the invention
The purpose of this invention is to provide a kind of tackifying polyamide 66 composition that can be used for the used for medical procedures high performance polymers pipes.
For realizing above purpose, technical scheme of the present invention provides a kind of tackifying polyamide 66 composition, it is characterized in that, it is made by following raw materials by weight percent:
Nylon 66 70-94.7,
Tackifier 0.1-25,
Compatilizer 4-20,
Nanometer grade silica 0.1-5,
Oxidation inhibitor 0.1-1.
The relative viscosity of described nylon 66 is 2.4-3.8PaS; Described tackifier are got vulcabond TDI, p-Hydroxybenzoate, 4,4-isopropylidene double-basis phenol salicylate, salicylic acid phenyl ester, ethylene glycol, phenol or phenyloxalate DPO; Described compatilizer is styrene-maleic anhydride copolymer SMA, ethylene-vinyl acetate copolymer EVA, maleic anhydride grafted polyethylene copolymer p E-g-MAH, maleic anhydride inoculated polypropylene copolymer p P-g-MAH, polyethylene acrylate grafts PE-g-AA, the polypropylene grafted thing PP-g-AA of vinylformic acid, glycidyl methacrylate-polyethylene graft copolymer GMA-g-PE or glycidyl methacrylate-polypropylene graft copolymer GMA-g-PP; Described nanometer grade silica particle diameter is the 40-60 nanometer; Described oxidation inhibitor is 1010 or 1010/168 (1: 1).
Preparation technology of the present invention is: said components was put into high-speed mixer and mixing 2-5 minute in proportion, used the screw extrusion press extruding pelletization then, processing temperature is at 240-300 ℃, and the screw rod revolution is at 180-600 rev/min.
Tackifier and nylon are by carrying out chemical reaction with the nylon end group in the course of processing, the molecular weight of nylon can be by permanent increase, reduce melt flow rate (MFR), increase nylon viscosity and can not take place crosslinkedly, can improve the resistance to impact shock and the elongation at break of material.
The adding of compatilizer can improve the viscosity of material, reduces melt flow rate (MFR).
The adding of nanometer grade silica can improve the tensile strength and the impact property of nylon material.
Oxidation inhibitor makes nylon 66 have good processing stability in the course of processing, avoids color and luster, performance to change.
The present invention adopts nylon 66 as matrix resin, make a kind of tackify nylon 66 composition, greatly improved the viscosity of nylon material, the flowing property of material is significantly changed, shock strength obviously improves, can be used for extruding or be blow molded into various thin-wall sections, particularly because good kindliness, high tenacity, the low-friction coefficient of this material, this material can be used for the used for medical procedures high performance polymers pipes.
Advantage of the present invention is the viscosity height, and melt flow rate (MFR) is low, can be used for the used for medical procedures high performance polymers pipes.
