Description

Technical Field

[0001] The invention belongs to the field of spray-free plastics, and relates to a spray-free flow pattern effect high-temperature injection molding plastic material and a preparation method thereof. Background Art

[0002] Engineering plastic products are widely used in automobiles, home appliances, daily necessities and other fields. In order to enhance the beauty and texture of plastic products and enrich consumers' visual experience, surface spraying of plastic products is widely used in plastic products. However, chemical solvents are required in the spraying process, which causes environmental pollution. Secondly, there are disadvantages such as long cycle and high cost. Spray-free plastics do not need spraying and can be made into aesthetic plastic products by injection molding in one time. Therefore, it is energy-saving and environmentally friendly, shortens the production cycle and reduces costs. With the development of spray-free materials, various differentiated appearance effects are constantly being developed to meet the personalized needs of different application scenarios.

[0003] The appearance effect of flow pattern on plastic products is achieved by adding flow pattern masterbatch into the base material. The melting temperature of the flow pattern masterbatch is higher than the injection temperature of the base material. There is a temperature difference between the plasticizing temperature of the injection molding base material and the melting temperature of the flow pattern masterbatch. During the injection molding process, the base material is melted, while the flow pattern masterbatch is in a semi-melted state, so that the flow pattern masterbatch flows naturally and is distributed on the surface of the product during the injection molding process, rather than the color being completely immersed in the base material, thereby producing the flow pattern effect. Chinese Patent CN 112745665 A discloses a polypropylene material injection molding flow effect masterbatch and a preparation method thereof, wherein the base material is polypropylene resin, and the flow effect components include PA6 resin, HDPE resin, compatibilizer, styrene-based elastomer, PP resin, etc. Chinese invention patent CN114634636A discloses a masterbatch with fluorescent flow effect and a preparation method and application thereof, wherein the base material is ABS resin, and the flow masterbatch components include PBT resin, PET resin, ABS resin, etc. Chinese patent CN113214566A discloses a flow masterbatch for PC / ABS material injection molding and a preparation method and application thereof, wherein the base material is PC / ABS alloy resin, and the flow masterbatch components include PC resin, PET resin, etc. Chinese patent CN116904010A discloses a spray-free flow effect polycarbonate (PC) plastic material and a preparation method thereof, wherein the flow effect masterbatch of the patent adopts PET resin, but since the base material processing temperature of the PC material is higher than the flow effect masterbatch PET resin, the PC material is modified to reduce the plasticizing temperature of the PC resin to achieve the flow effect of the PC plastic material. Summary of the invention

[0004] The purpose of the present invention is to provide a spray-free high-temperature injection molding plastic material with flow effect and a preparation method thereof in view of the problems existing in the prior art. The flow effect is formed by adding a flow effect masterbatch with a processing temperature higher than that of the base material to the base material. During the injection molding process, the base material melts, while the flow masterbatch is in a semi-melted state. When the processing temperature of the base material is high, and the processing temperature is higher than that of the flow effect masterbatch, the flow effect masterbatch will completely melt, and the color of the flow effect masterbatch will be completely immersed in the base material, and the flow effect cannot be formed. The high heat-resistant flow effect masterbatch developed by the present invention has a higher processing temperature, is suitable for PC / ABS (PC content higher than 70%) and PC materials, and can form a stable flow effect within its processing temperature range.

[0005] The purpose of the present invention can be achieved by the following scheme:

[0006] <First aspect>

[0007] The present invention provides a spray-free flow effect high-temperature injection molding plastic material, wherein the spray-free flow effect polycarbonate plastic material comprises a high-temperature injection molding plastic material and a high heat-resistant flow effect masterbatch; wherein the high-temperature injection molding plastic material comprises the following components in parts by weight:

[0008]

[0009] The high heat-resistant flow effect masterbatch comprises the following components in parts by weight:

[0010]

[0011] High-temperature injection molding plastic materials refer to materials with a processing temperature exceeding 260°C (this temperature is the injection molding temperature, and the industry generally refers to the temperature of Zone 1), including PC / ABS and PC, where the PC content exceeds 70%.

[0012] As an embodiment, in the high-temperature injection molding plastic material, the content of polybutadiene in the polyacrylonitrile-styrene-butadiene copolymer is 10 wt.% to 30 wt.%.

[0013] The flow effect masterbatch requires that most of the base material is a crystalline polymer. As an embodiment of the present invention, the high heat-resistant flow effect masterbatch resin matrix of the present invention uses polyhexamethylene adipamide (PA66) with a characteristic viscosity of 2.0dl / g to 3.0dl / g. The difficulty of PC flow is that the processing temperature of PC is high, and there are few materials that have crystallinity and high processing temperature and are compatible with PC. The injection molding temperature of PA66 used in the present invention is 290-315℃, and the melting point of PA66 is more than 260 degrees. The injection molding temperature of 280-290℃ is required to form flow. If PA6 is selected, the flow effect cannot be formed under high temperature injection molding conditions.

[0014] In the system of the present invention, the PC melt index in the masterbatch needs to be lower than the PC melt index in the base material in order to improve the stability of the flow pattern formation, specifically to prevent the flow pattern masterbatch from quickly blending into the base material during injection molding. In some implementation examples, the polycarbonate resin in the selected high-temperature injection molding plastic material has a melt index of 10 to 60 g / 10 min under the condition of 300°C*1.23g. The polycarbonate resin in the selected high-heat-resistant flow pattern effect masterbatch has a melt index of 3 to 10 g / 10 min under the condition of 300°C*1.23g.

[0015] As an embodiment of the present invention, the toughening agent is selected from long-chain toughening agent grafted with maleic anhydride; including POE grafted with maleic anhydride, EVA grafted with maleic anhydride, EMA grafted with maleic anhydride, etc. In the system of the present invention, the long-chain toughening agent (such as POE, etc.) grafted with maleic anhydride plays the role of a toughening agent, which can toughen PC and PA66 at the same time; at the same time, as a compatibilizer, it improves the compatibility of high-temperature injection molding plastic materials and high-heat-resistant flow effect masterbatches during injection molding. MBS has obvious toughening efficiency for PC, but cannot improve the compatibility of high-temperature injection molding plastic materials and high-heat-resistant flow effect masterbatches.

[0016] As an embodiment of the present invention, the antioxidant 1# includes one of antioxidant 1010 and antioxidant 1076.

[0017] As an embodiment of the present invention, the antioxidant 2# includes one of antioxidant 168 and antioxidant 300. The two antioxidants have different working principles and the compounding efficiency is higher.

[0018] As an embodiment of the present invention, the lubricant is high heat-resistant PETS. Due to the high processing temperature, a high heat-resistant lubricant needs to be used.

[0019] As an embodiment of the present invention, the weathering agent is a benzotriazole weathering agent, including hydroxyphenylbenzotriazole.

[0020] As an embodiment of the present invention, the color powder includes one or more of pigment and effect powder. The effect powder includes one or more of metal, pearl, glass, and mica. The color powder is not limited to conventional pigments, but also includes metal, pearl, glass, mica and other effect powders according to actual color matching requirements.

[0021] As an embodiment of the present invention, the addition ratio of the flow effect masterbatch is 0.1wt.% to 15wt.% of the weight of the high-temperature injection molding plastic material base material, and the specific amount is mainly based on the appearance requirements of the client.

[0022] <Second Aspect>

[0023] The present invention also provides a method for preparing a spray-free flow pattern effect high-temperature injection molding plastic material, comprising the following steps:

[0024] S1. Preparation of high heat-resistant flow effect masterbatch

[0025] The polyhexamethylene adipamide, polycarbonate, antioxidant 1#, antioxidant 2#, lubricant, weathering agent and color powder are mixed and added into a twin-screw extruder, and granulated by melt extrusion to obtain a flow effect masterbatch for standby use;

[0026] S2. Preparation of high temperature injection molding plastic materials

[0027] The polycarbonate, polyacrylonitrile-styrene-butadiene copolymer, toughening agent, antioxidant 1#, antioxidant 2#, lubricant, weathering agent, and color powder are mixed and added into a twin-screw extruder, and granulated by melt extrusion to obtain a high-temperature injection molding plastic material;

[0028] S3. Preparation of high temperature injection molding plastic material with spray-free flow effect

[0029] The high temperature injection molding plastic material is used as a base material, and a high heat-resistant flow effect masterbatch is added to the base material to obtain a spray-free flow effect high temperature injection molding plastic material. In this step, the two materials can be mechanically mixed.

[0030] As an embodiment of the present invention, in step S1, the temperature of the first to fifth zones of the twin-screw extruder is 230-250°C, 240-260°C, 250-270°C, 260-280°C, 270-290°C, and the twin-screw speed is 400-600r / min, wherein the higher the PC content, the higher the temperature. The above temperature is the twin-screw granulation temperature, and the injection molding temperature is generally higher than the twin-screw granulation temperature, such as 10-30°C higher.

[0031] As an embodiment of the present invention, in step S2, the temperatures of zones 1 to 5 of the twin-screw extruder are 230-240°C, 230-250°C, 240-260°C, 250-270°C, and 260-280°C, respectively, and the twin-screw speed is 400-600r / min.

After injection molding, a spray-free flow pattern effect high-temperature injection molded plastic material part can be obtained.

[0034] Compared with the prior art, the present invention has the following beneficial effects:

[0035] In order to prevent the flow pattern masterbatch from being completely melted at the high temperature injection molding temperature and failing to form the flow pattern effect, the present invention prepares a high heat-resistant flow pattern effect masterbatch. The prepared high heat-resistant flow pattern effect masterbatch can be processed at a temperature higher than the flow pattern masterbatch, thereby utilizing the temperature difference between the base material plasticization and the flow pattern masterbatch to form the flow pattern effect.
