Abstract
The invention relates to a nylon toughening masterbatch and a preparation method thereof. The nylon toughening masterbatch is prepared by taking a polyolefin elastomer, nylon, a grafting monomer, an initiator, a diluent and a coating agent as raw materials through the steps of mixing the raw materials, adding the obtained mixture into an extruder, carrying out molten plasticizing, and sequentially extruding, granulating, cooling, dewatering and drying the obtained product. According to the invention, the grafting of the polyolefin elastomer and the manufacturing of the nylon toughening masterbatch are completed in one step, and the toughening masterbatch can be directly applied to the toughening of nylon injection products so as to increase the toughness of the nylon products. Because the nylon toughening masterbatch is manufactured by using a one-step method, energy sources can be saved, the processing cost is lowered, and the degradation of polymers is reduced.
Description
Technical field
The invention belongs to the preparation field of master batch, particularly a kind of toughening nylon master batch and preparation method thereof.
Background technology
Nylon is one of five large general engineering plastic, and output is large, purposes is wide, has excellent physical strength, and has heat-resisting, oil resistant, weak acid resistant, alkaline-resisting and common solvent, and nontoxic, odorless, electrical insulating property is good, the outstanding advantages such as good weatherability.But nylon exists the general shortcoming of notch shock performance, this greatly limits its application.
Thermoplastic polymer is toughness reinforcing three kinds of different mechanism: organic rigid-particle toughening mechanism, rigid inorganic filler toughening mechanism and elastic body toughening mechanism.Nylon is thermoplastic polymer, it is toughness reinforcing with the best results of elastic body toughening, namely by the chemical modification method function monomer that grafting can be worked as with nylon molecules generation chemical reaction or polar phase on the polyolefin elastomer molecule of softness of graft copolymerization, polyolefin elastomer is made to be evenly dispersed in nylon matrix with molecule and to form firmly interfacial layer with nylon.When being subject to foreign impacts, first soft polyolefin elastomer absorbs energy, produces Voiding and surrender, and then transmits initiation crazing and shear zone by interface, a large amount of consumed energy, macroscopically play the effect improving material impact intensity.
Ethylene-alpha-octylene copolymers or ethylene-butene copolymer (POE) are current widely used polyolefin elastomers, and they have excellent snappiness.After carrying out polar monomer graft modification by copolymerization to POE, originally nonpolar POE is just endowed certain polarity and reactive behavior, can effectively be distributed in nylon, thus improves notched Izod impact strength and the ductility of nylon.
Nylon products is all much manufacture shaping with Shooting Technique, when goods flexible performance index require, usually reach in the following manner: 1, first graft modification is carried out to polyolefin elastomer, and then the elastomerics after grafting is joined injection moulding together in nylon in suitable ratio.Because the short mixed effect of screw in injection molding machine is not good, toughner dispersion is bad, causes final toughening effect undesirable.Simultaneously need 90-110 DEG C of heat-wind circulate dryings during nylon injection-molding, and polyolefine toughener often fusing point is lower, easily melt in the course of processing, cause nylon particles to lump, affect injection moulding blanking; 2, first graft modification is carried out to polyolefin elastomer, then the elastomerics after grafting is joined in nylon with higher proportion and make toughening nylon master batch by double-screw extruding pelletizing, finally add plasticizing mother particle in nylon injection moulding in proportion.Method 2 can the defect of solution 1 well, but will make tenacity increased nylon master batch in advance, increases by one manufacturing procedure, cause cost higher than first method, the processing number of times of superpolymer process is more simultaneously, degrades also more serious, affects the performance of final injection-molded item.
