Abstract
The invention discloses a modified polymethyl methacrylate (PMMA) transparent material, which comprises the following components in parts by weight: 20-80 parts of PMMA, 20-80 parts of SAN (Styrene-Acrylonitrile) and 5-30 parts of MBS (Methacrylate-Butadiene-Styrene), wherein the sum of the parts of the PMMA and the SAN is 100. The PMMA, the SAN and the MBS are prepared into a product in a melt blending and extruding mode; the MBS is used as a modifier to be added into the PMMA/SAN blend, so that the compatibility of the PMMA and the SAN is improved; when the PMMA/SAN is in a range of 40/60 to 55/45, the transparency of the MBS is hardly affected while the impact toughness of the MBS is greatly improved; and thus the modified polymethyl methacrylate transparent material has relatively high impact toughness and transparency. A preparation method provided by the invention has the advantages of simple process, easiness in operation and extreme suitability for industrial production.
Description
Technical field
The present invention relates to material science, especially a kind of macromolecular material and preparation method thereof.
Background technology
Polymethylmethacrylate (PMMA) is commonly called as synthetic glass; It is one of transparent best kind in the present plastics; Have outstanding stability to aging and chemicalstability; Good insulation performance property and processibility do not have unrelieved stress, have been widely used in fields such as agricultural, aviation, building, opticinstrument, decorative lamp.But compare with other transparent plasticss, the PMMA shock strength is low, and is heat-resisting, wear-resisting and scratch resistance is poor, and its application is restricted.
Extensive work to the PMMA blending and modifying concentrates on blend and the copolymerization.There is the method for human TEB 3K in-situ polymerization to prepare the EVA/PMMA light transmissive composite materials; Mixing the second phase particle is the important form of blending and modifying; It also is the most important approach of plastic toughening; Except rubber toughened; Lot of domestic and foreign investigator has also carried out extensive studies to other second mutually particle-filled PMMA matrix material, considers the light transmission of matrix material, generally all selects nanoparticle for use.
Summary of the invention
The objective of the invention is: a kind of modified poly (methyl methacrylate) material and preparation method thereof is provided, and it has the good transparency and impelling strength, and with low cost, and thermotolerance also improves a lot, to overcome the deficiency of prior art.
The present invention is achieved in that the modified poly (methyl methacrylate) material, calculates by weight, comprises 20～80 parts of PMMA, 20～80 parts of SAN and 5～30 parts of MBS; The umber summation of PMMA and SAN is 100 parts.
Preferred scheme has four:
1, calculates by weight, comprise 40 parts of PMMA, 60 parts of SAN and 5～30 parts of MBS.
2, calculate by weight, comprise 45 parts of PMMA, 55 parts of SAN and 5～30 parts of MBS.
3, calculate by weight, comprise 50 parts of PMMA, 50 parts of SAN and 5～30 parts of MBS.
4, calculate by weight, comprise 55 parts of PMMA, 45 parts of SAN and 5～30 parts of MBS.
The PMMA melting index is 16g/10min.
Acrylonitrile content is 16～20% among the SAN.
The modified poly (methyl methacrylate) preparation methods with PMMA, after SAN and MBS mix, obtains mixture; Mixture added carries out melt blending in the twin screw extruder and extrude, and with the material of extruding through cooling, dry, pelletizing, obtain finished product.
Extrusion temperature is 190～230 ℃, and the screw speed of twin screw extruder is 300rad/min.
In the application of PMMA; Its cost and impelling strength usually are considerable important factors, and transparency, the hardness of styrene-acrylonitrile copolymer (SAN) resin all approach PMMA, especially intensity; Thermotolerance, aspects such as production cost all are superior to PMMA.
MBS is grafted on polyhutadiene (PB) or butadiene-styrene rubber (SBR) macromolecular chain and the graft copolymer that forms by TEB 3K (MMA) and vinylbenzene (ST).In MBS, contain rubber bead and plastic components.Wherein, the rubber bead can play tangible toughening modifying effect, and MBS and PMMA and SAN all have consistency well.
Compared with prior art; The present invention prepares product with the mode that PMMA, SAN and MBS extrude through melt blending; MBS joins the consistency that has not only improved them in the PMMA/SAN blend as a kind of properties-correcting agent, and when improving its impelling strength greatly, its transparency is not but had considerable influence.Preparing method's technology of the present invention is simple, easy to operate, very suitability for industrialized production.
