Description
WEATHER-RESISTANT ASA-BASED COMPOSITE MATERIAL, 4501799
CO-EXTRUDED PLASTIC PRODUCT AND PLASTIC PRODUCT
[01] The present invention relates to the technical field of polymer composite materials, and in particular to a weather-resistant ASA-based composite material, a coextruded plastic product and a plastic product.
[02] At present, with the development of science and technology as well as the continuous improvement of people's living standards, polymer materials are being increasingly applied in various fields in daily life, for example, living plastic products, automobile parts and electrical appliance housings. Especially for some long-term exposed plastic products, on one hand, a smooth appearance is required, and on the other hand, higher mechanical strength, impact resistance and weather resistance are expected.
[03] At present, to improve the mechanical strength of plastic products, hard materials such as plastics are molded together by means of a co-extrusion molding process. Further, to improve product properties such as the toughness, impact resistance and corrosion resistance, generally, various components are compounded to form alloy polymer composites. For example, at present, the widely applied plastic products take
ABS as the main component, which is compounded with PMMA, PVC or PC, and has the characteristics of excellent impact resistance, heat resistance, low temperature resistance, chemical resistance, electrical performance, etc. However, ABS plastics have poor weather resistance and is not suitable for outdoor products, making it a major limitation for the ABS plastics.
[04] In view of this, the present invention provides a weather-resistant ASA-based composite material with excellent weather resistance and high gloss, a co-extruded plastic product and a plastic product comprising the composite material.
[05] A weather-resistant ASA-based composite material comprises the following components by mass: 1
[06] acrylonitrile-styrene copolymer 20-84%, LU501799
[07] acrylonitrile-acrylic acid-styrene copolymer 10-70%,
[08] acrylic resin 5-30%,
[09] auxiliary agent 1-10%,
[10] wherein the acrylonitrile-acrylic acid-styrene copolymer is of a core-shell structure, with polyacrylic resin rubber as a core and the acrylonitrile-styrene copolymer as a shell.
[11] A co-extruded plastic product comprising a first co-extruded material and a second co-extruded material, wherein the second co-extruded material is co-extruded on a surface of the first co-extruded material in a form of a co-extruded film, wherein the second co-extruded material is the above weather-resistant ASA-based composite material.
[12] A plastic product, comprising the above weather-resistant ASA-based composite material.
[13] The above weather-resistant ASA-based composite materials and products contain an acrylonitrile-styrene copolymer, an acrylonitrile-acrylic acid-styrene copolymer in a core-shell structure and an acrylic resin, wherein the acrylonitrile-acrylic acid-styrene copolymer in a core-shell structure provides excellent weather resistance for the composite materials, while the acrylonitrile-styrene copolymer has high temperature resistance, excellent gloss and chemical medium resistance, excellent hardness, rigidity, dimensional stability, etc. The acrylic resin enables better compatibility of acrylonitrile-acrylic acid-styrene copolymer and acrylonitrile-styrene copolymer in a core-shell structure, and improves the surface hardness and brightness of the composite material. By mixing with ASA, the product is more resistant to aging and scratching.
[14] To make the purpose, technical scheme and advantages of the present invention more clearly, the present invention will be further described in detail below with examples. It should be understood that the specific embodiments described here are only used to explain the present invention without limiting the present invention.
[15] The embodiment of the present invention provides a weather-resistant
ASA-based composite material, which comprises the following components by mass: 2
[16] acrylonitrile-styrene copolymer 20-84%, LU501799
[17] acrylonitrile-acrylic acid-styrene copolymer 10-70%,
[18] acrylic resin 5-30%,
[19] auxiliary agent 1-10%,
[20] wherein the acrylonitrile-acrylic acid-styrene copolymer is of a core-shell structure, with polyacrylic resin rubber as a core and the acrylonitrile-styrene copolymer as a shell.
[21] Specifically, the content of the acrylonitrile-styrene copolymer is preferably 50-70%, and more preferably 55-65%. The acrylonitrile-styrene copolymer, AS or SAN for short, has a high glass transition temperature, high temperature resistance, high gloss, excellent chemical stability, excellent hardness, rigidity, dimensional stability and high bearing capacity. Generally, acrylonitrile and styrene are taken as raw materials and prepared by a suspension method or an emulsion polymerization method. The acrylonitrile-styrene copolymer, as one of the main components of the composite material in the embodiment of the present invention, improves properties such as transparency, luster, hardness and temperature resistance of the composite material.
[22] The acrylonitrile-acrylic acid-styrene copolymer (ASA) is of a core-shell structure, with the acrylonitrile-styrene copolymer being grafted on the polyacrylic resin rubber. The preparation method of that component comprises the following steps: firstly, polymerizing to form polyacrylic resin rubber, taking an acrylic polymer as core particles, and grafting an acrylonitrile-styrene copolymer onto the core particles through a grafting polymerization process to form an acrylonitrile-acrylic acid-styrene copolymer in a core-shell structure. In the preparation process, the grafting rate and molecular weight of the acrylonitrile-styrene copolymer have a great influence on the physical properties of acrylonitrile-acrylic-styrene copolymer in a core-shell structure.
For example, high-fluidity ASA can be obtained by grafting with a high-fluidity acrylonitrile-styrene copolymer, high-fluidity injection-molded ASA can be obtained by grafting with acrylonitrile-styrene copolymer with a higher fluidity, a high heat-resistant
ASA can be obtained by grafting with more heat-resistant acrylonitrile-styrene copolymer and high-hardness acrylonitrile-styrene copolymer, a extrusion grade AEA can be obtained by grafting with high hardness acrylonitrile-styrene copolymer. The mass percentage of the acrylonitrile-acrylic acid-styrene copolymer is preferably 10-50%, and more preferably 25-35%. ASA can remarkably improve the weather resistance and heat resistance of the composite material, and can also improve various 3 mechanical properties of the material, such as impact resistance, notch sensitivity, LU501799 solvent cracking resistance and tensile strength.
[23] The acrylic resin can be but not limited to methyl methacrylic resin (MMA), and its mass percentage in the composite material is preferably 10-50%. MMA enables better compatibility of —acrylonitrile-acrylic acid-styrene copolymer and acrylonitrile-styrene copolymer in a core-shell structure, and improves the surface hardness and brightness of the composite material. By mixing with ASA, MMA is more resistant to aging and scratching.
[24] The auxiliary agent comprises the following components by mass: a lubricant of 0.5-4%, an antioxidant of 0.01-0.6% and an ultraviolet light absorbent of 0.01-0.6%.
The lubricant is silicone, ethylene bis stearamide (EBS) or pentaerythritol stearate (PETS), and more preferably pentaerythritol stearate. PETS has excellent thermal stability, even at high temperature, it has excellent thermal stability and low volatility, excellent demolding and flow performance, which is beneficial to extrusion or molding and provides excellent nucleation effects. PETS is an effective lubricant for many polymers in the process of extrusion or molding, molding without degradation.
Moreover, it can significantly improve transparency and surface smoothness. Moreover, due to the high efficiency of PETS, the usage amount of PETS can be lower than that of most traditional lubricants, and the usage amount of PETS is preferably 0.5-1%, so as to realize an excellent lubricating effect.
[25] The antioxidant may be, but is not limited to, EPDM, phenyl tris (2,4-di-tert-butyl) phosphite, benzoquinone, hindered phenols, etc. EPDM is preferred in this embodiment. The ultraviolet absorber may be, but not limited to, benzophenone compounds, benzotriazole compounds, hindered amine light stabilizers or cyanoacrylic resins. Because there are many kinds of polymers in the composite material of this example, the polymers are sensitive to light and heat, which will result in autocatalytic degradation reaction (aging). Therefore, adding an appropriate UV-proof agent and an antioxidant can complement each other to improve its stability and oxidation resistance.
[26] Furthermore, the composite material of this embodiment also includes 0.5-10% polytetrafluoroethylene by mass. By adding polytetrafluoroethylene into the composite material, the molded product is more scratch resistant, weather resistant and temperature resistant, and also provides an auxiliary lubricating effect. The mass percentage of polytetrafluoroethylene is preferably 1-2%. Because the modified composite material is easy to color, for example, easier to color than PVC, it is an 4 excellent choice in coextrusion molding, especially suitable for profiles whose surface is LU501799 exposed outdoors for a long time. Therefore, preferably, the composite material is further added with 1-6% of a pigment, for example, inorganic pigments and organic pigments with high weather resistance and sun resistance, to form a colored ASA-based composite material, wherein the inorganic pigments can be titanium dioxide, chrome yellow, iron oxide yellow and the like, and the organic pigments are preferably azo pigments. When applied, it can be made into colored plastic products and colored co-extrusion film to satisfy the actual environmental requirements.
[27] The embodiment of the present invention also provides a co-extruded plastic product formed by co-extrusion of the ASA-based composite material, which comprises a first co-extruded material and a second co-extruded material, wherein the second co-extruded material is formed on the surface of the first co-extruded material in a form of a film covering, and the second co-extruded material is the ASA-based composite material. The first co-extruded material is a polymer material or plastic, such as PVC and polyvinyl chloride (UPVC). The first co-extruded material forms the body structure of the product, and the ASA-based composite material is coated on the surface of the body structure. Taking the special-shaped plastic-steel doors and windows as an example, the first co-extruded material is PVC as the special-shaped profile of doors and windows. The granulated ASA-based composite material is co-extruded on the profile surface in a form of film covering, which generally has one or more surfaces for decoration (for example, when pigments are added, the surface of colored weather-resistant ASA-based composite film can be formed). Among them, ASA-based composite film has excellent adhesiveness with PVC profile, is not easy to the delaminate, has excellent toughness, high impact resistance and excellent fluidity, and its co-extrusion layer can be uniform even at the thinnest part in the process of co-extrusion, while some existing film materials such as PET are not easy to process, and the co-extrusion is uneven and the bonding force is poor. The weather resistance, temperature resistance, scratch resistance and brighter surface of the product are improved by coating the surface of the weather-resistant ASA-based composite material.
[28] The embodiment of the present invention also provides a plastic product, which comprises the ASA-based composite material and is made of the composite material through various processes such as extrusion molding or injection molding. The application of plastic product includes, but is not limited to, plastic parts in household appliances, automobile parts, doors and windows, household appliances, household LU501799 appliances, computers and their accessories, audio products, furniture, toys, automobile interiors, lampshades, lamps, vehicle interiors, sunshades, cosmetic boxes, handicrafts, decorations, hairdressing products, etc.
