Description
Technical Field
The invention relates to the field of high polymer materials, in particular to a fingerprint-resistant highlight black PMMA/ASA composition and a preparation method thereof.
Background
Polymethyl methacrylate (PMMA) is commonly called organic glass and acrylic, has light transmittance and mechanical property, is excellent in ageing resistance and weather resistance, has stable chemical property, and can resist general chemical corrosion of low-concentration acid, alkali and the like. But PMMA is brittle and has poor drop hammer impact properties, especially low temperature impact properties. In the automotive field, PMMA resins can be used in window glass, hood, instrument glass, car lights, signs and the like.
Butyl acrylate-styrene-acrylonitrile terpolymer (ASA) has similar structure and performance to Acrylonitrile Butadiene Styrene (ABS), but the ABS contains residual double bonds, so that the weather resistance of the ABS is reduced, and the ASA replaces butadiene with butyl acrylate, and the residual double bonds are not present, so that the weather resistance of the ASA resin is obviously better than that of the ABS resin. ASA resins have good impact resistance, colorability, chemical resistance, but suffer from insufficient surface hardness, poor scratch and scratch resistance. ASA resin is mainly applied to exterior trimming parts such as a grid, triangular blocks, column plates and the like in automobiles.
PMMA/ASA material has excellent scratch resistance and weather resistance, and in addition, the excellent highlight black effect is difficult to achieve by other high polymer materials, so that PMMA/ASA alloy is widely applied to high-light black parts such as automobile grids, upright posts, rearview mirrors and the like. However, the highlight black products prepared with PMMA/ASA materials tend to be fingerprint-prone due to their hydrophilicity, i.e., relatively high polarity, which detracts from the highlight black effect. The fingerprint resistance of the highlight black material is also an industry problem.
Disclosure of Invention
The invention aims to overcome at least one of the defects in the prior art and provide a fingerprint-resistant highlight black PMMA/ASA composition capable of ensuring good compatibility of PA6/66-g-MAH and PMMA/ASA resin and achieving obvious fingerprint-resistant effect and a preparation method thereof.
The aim of the invention can be achieved by the following technical scheme:
A fingerprint resistant highlight black PMMA/ASA composition comprising polymethyl methacrylate (PMMA), acrylonitrile-acrylate-styrene copolymer (ASA), self-cleaning modifier PA-g-MAH and other adjuvants; wherein the mass ratio of polymethyl methacrylate (PMMA), acrylonitrile-acrylic ester-styrene copolymer (ASA) and self-cleaning modifier PA-g-MAH is (50-80): 20-40): 5-10.
Further, the mass ratio of polymethyl methacrylate (PMMA), acrylonitrile-acrylic ester-styrene copolymer (ASA) and self-cleaning modifier PA-g-MAH is (50-65): 25-40): 5-10.
Further, the composition comprises the following components in parts by weight:
Further, the polymethyl methacrylate (PMMA) has a weight average molecular weight of 50000-150000; the particle size of the acrylonitrile-acrylic ester-styrene copolymer (ASA) is below 300nm, and the mass content of the rubber is 20-60%; in the PA-g-MAH, the mass content of the MAH is more than 1%.
Further, the self-cleaning modifier PA-g-MAH is maleic anhydride grafted polyamide resin, and the preparation method is as follows: after mixing maleic anhydride and polyamide, reactive coextrusion is carried out to obtain PA-g-MAH.
Further, the polyamide is PA6 or PA66, and the weight average molecular weight is below 15000, for example, the weight average molecular weight is 10000-15000.
Too high a molecular weight may result in failure to precipitate to the surface, making it difficult to achieve fingerprint resistance, while too low a molecular weight has a large impact on mechanical properties.
Further, the mass ratio of the maleic anhydride to the polyamide is (1-5) (95-99), and the temperature is 210-220 ℃ during reactive coextrusion.
Further, the antioxidant comprises one or more of commercial antioxidant 245, antioxidant 1076 or antioxidant 168; the lubricant comprises one or more of silicone powder, pentaerythritol ester or ethylene bis-stearamide; the black toner is organic dye black toner.
A method of preparing a fingerprint resistant highlight black PMMA/ASA composition as described above, the method comprising the steps of:
Mixing polymethyl methacrylate, acrylonitrile-acrylic ester-styrene copolymer, self-cleaning modifier PA-g-MAH, antioxidant, lubricant and black toner according to mass parts;
And (3) blending and granulating the mixture by a double-screw extruder, and carrying out melt extrusion to obtain the fingerprint-resistant highlight black PMMA/ASA composition.
Further, during blending granulation, the rotating speed of the screw is 400-600rpm; the rotating speed is too high, the extrusion time is insufficient, the self-cleaning modifier and PMMA/ASA are difficult to be fully compatible, and the rotating speed is too low, so that the full plasticization of the resin base material can not be ensured; the diameter of the extruder screw is 55-60mm, and the length-diameter ratio is (50-70): 1; in the melt extrusion, the extrusion temperature is 220-260 ℃.
Compared with the prior art, the invention prepares the maleic anhydride grafted polyamide (PA 6/66-g-MAH) with low molecular weight, and the maleic anhydride grafted polyamide is added into PMMA/ASA resin as a self-cleaning auxiliary agent for blending. The PA6/66-g-MAH migrates to the surface of the material during injection molding, and because the PA6/66-g-MAH contains a large amount of polyamide functional groups, moisture can achieve the effect of cleaning the surface after moisture absorption, so that fingerprints on the surface of the highlight black material are cleaned, namely fingerprint resistance, and the maleic anhydride functional groups in the PA6/66-g-MAH can ensure good compatibility with PMMA/ASA resin. The PA6/66-g-MAH prepared by the method can achieve obvious fingerprint resistant effect after being added into PMMA/ASA alloy for blending.

The particle size of ASA rubber is below 300nm, and the rubber content is 20-60%; the self-cleaning modifier is self-prepared maleic anhydride grafted polyamide resin PA-g-MAH, wherein the polyamide can be PA6 or PA66, the molecular weight is below 15000, too high molecular weight can lead to incapability of separating out to the surface, fingerprint resistance effect is difficult to realize, too low molecular weight has larger influence on mechanical properties, and the MAH content is above 1%; the antioxidant comprises one or more of commercially available antioxidant 245, antioxidant 1076 and antioxidant 168; the lubricant comprises one or more of silicone powder, pentaerythritol ester and ethylene bis-stearamide; the black toner is organic dye black toner;
The mixture obtained after the above stirring was fed through the main feeding port of a twin-screw extruder, the screw diameter of the extruder used was 58mm, and the aspect ratio was 60. Blending and granulating, wherein the extrusion temperature is 220-260 ℃, the screw speed of an extruder is 400-600rpm for ensuring the extrusion and blending time, and the fingerprint-resistant highlight black PMMA/ASA alloy is obtained through the steps of full melt extrusion and granulating.
Examples
The following raw material components are respectively weighed according to the weight parts ratio shown in the table 1: PMMA, ASA, PA6-g-MAH, antioxidant, lubricant and black dye are stirred uniformly in a high-speed mixer. Feeding the mixture obtained after uniform stirring through a main feeding port of a double-screw extruder, wherein the extrusion temperature is 240 ℃, the screw speed is 500rpm, and carrying out physical property test and injection molding and plate forming evaluation on particles obtained after strand granulation.
The preparation method of the PA6-g-MAH in examples 1-4 comprises the steps of selecting Xinhuimeda PA6M2000 as a resin carrier, performing GPC test to obtain a weight average molecular weight of 12500, fully mixing 2% by weight of maleic anhydride and 98% by weight of PA6M2000 in a high-speed premixing machine, performing reactive coextrusion in a twin-screw extruder with an aspect ratio of 44:1, controlling the extrusion temperature to 210-220 ℃ and the rotating speed to 600rpm, extruding a draw bar, and obtaining the PA6-g-MAH, wherein the content of the MAH is 1.2% according to an anhydride titration method test result.
Comparative example 3 differs from example 1 in that PA6 was selected as the resin carrier, PA6-1013B from yuchen corporation, GPC weight average molecular weight test 22500, and PA6M1000 from new merda was selected as the resin carrier of PA6-g-MAH, GPC molecular weight test 8700, wherein it should be noted that new merda PA6M1000 was not formally commercially available for use only by deep partners as improvement in fluidity and research due to lower polymerization degree, poor performance.

Table 2 characterization of examples, comparative examples
Because of the high heat resistance and density of PMMA, the density and Vicat softening temperature of the material are mainly related to the ratio of PMMA to ASA. As can be seen from comparative examples 1 and 1, the impact strength of the materials is obviously improved from 7.8KJ/m 2 to 12.5KJ/m 2 after the PA6-g-MAH is added, which shows that the addition of the PA-g-MAH improves the compatibility of the materials, refines the phase structure of the blend, ensures that the rubber is more uniformly dispersed, and obviously improves the impact strength of the materials. When the PA-g-MAH content was increased from 5 to 10 parts by weight, the impact strength of PMMA/ASA alloy was also significantly improved.
After the highlight template is stained with the fingerprint, the disappearance time of the fingerprint on the template surface is recorded, and the gloss of the template surface is tested after 24 hours. As can be seen from the data, the addition of PA-g-MAH can obviously shorten the fingerprint disappearance time, the PMMA/ASA highlight template added with 10 parts by weight of PA-g-MAH can restore to more than 90% of the original gloss after being stained with the fingerprint for 24 hours, the self-cleaning fingerprint prevention effect is obvious, the fingerprint disappearance time of the highlight surface can be shortened to 5-6 hours after the PMMA/ASA template added with PA-g-MAH is stained with the fingerprint by recording the fingerprint disappearance time, and the fingerprint can not disappear within 24 hours after the PMMA/ASA template added with PA-g-MAH is stained with the fingerprint.
In conclusion, the highlight PMMA/ASA composition prepared by the invention can realize excellent fingerprint resistance and oil stain resistance effects of the highlight spray-free product.
