Description

Technical Field

[0001] The present application relates to the field of plastic alloys, and more specifically, to a PC-ABS automobile interior material containing glass fiber and a preparation method thereof. Background Art

[0002] ABS plastic is a ternary copolymer of acrylonitrile (A), butadiene (B), and styrene (S). The relative content of the three monomers can be changed arbitrarily to make various resins. ABS plastic has the common properties of the three components. A makes it resistant to chemical corrosion and heat, but its surface hardness is lower than that of PC. B makes it highly elastic and tough. S makes it have the processing and molding characteristics of thermoplastics and improves electrical properties. At the same time, ABS also has better processing fluidity. Therefore, ABS plastic has been widely used in manufacturing industries such as machinery, electrical, textile, automobile, aircraft, and shipbuilding, as well as chemical industry.

[0003] PC is polycarbonate, also known as PC plastic; it has the advantages of being colorless and transparent, heat-resistant, impact-resistant, flame-retardant BI grade, better wear resistance than ABS, and good mechanical properties, but it has high viscosity and is prone to stress cracking.

[0004] Therefore, ABS and PC are currently used in combination to combine their properties so that they can be used in the production of electronic product housings, automotive interior parts, etc. They have better mechanical properties and can reduce the damage and cracking of electronic product housings and automotive interior parts when they are hit. However, ABS and PC are mainly synthesized from petroleum raw materials, and a large amount of carbon dioxide, carbon monoxide and other substances will be emitted during their production process, which will increase carbon emissions, reduce their environmental friendliness, cause certain damage to the atmosphere, and at the same time aggravate the trend of global warming.

[0005] In order to reduce carbon emissions and reduce the impact on the environment, there is currently a method of compounding recycled ABS and recycled PC to reduce carbon emissions and be more environmentally friendly. However, the impurity content in recycled ABS and PC materials is high and the performance is unstable; and the toughness and strength of the compounded recycled ABS and recycled PC composite materials are lower than those of ABS and PC composite materials. Therefore, when used in automotive interior parts, when subjected to force or impact, they are prone to breakage and cracking, thereby reducing their practicality, so further research is needed. Summary of the invention

[0006] In order to reduce carbon emissions and obtain better mechanical properties, the present application provides a PC-ABS automotive interior material containing glass fiber and a preparation method thereof.

[0007] In a first aspect, the present application provides a PC-ABS automotive interior material containing glass fiber, which is composed of the following raw materials in parts by weight:

[0008] ABS: 10-20 copies

[0009] PC: 5-8 copies

[0010] Recycled ABS: 30-40 pieces

[0011] Recycled PC: 10-20 pieces

[0012] Glass fiber: 20-40 parts

[0013] Compatibilizer: 5-10 parts

[0014] Other additives: 3-5 parts;

[0015] The compatibilizer is one or more of maleic anhydride grafted POE, maleic anhydride grafted EAA, and ethylene-butyl acrylate-glycidyl methacrylate copolymer.

[0016] The above raw material composition and raw material dosage are the preferred ranges of this application. By utilizing new ABS and PC materials and blending them with recycled ABS and recycled ABS, the new and the old are combined to comprehensively improve their performance. At the same time, it can reduce carbon emissions and improve its environmental friendliness.

[0017] Adding glass fiber, which is the abbreviation of glass fiber, has the advantages of good insulation, strong heat resistance, good corrosion resistance, and high mechanical strength. Adding glass fiber can further improve the strength and heat resistance of PC-ABS automotive interior materials.

[0018] Compatibilizers can promote the mixing and compatibility of various raw materials to enhance the interfacial adhesion of the raw material system, thereby further improving the comprehensive performance of PC-ABS automotive interior materials.

[0019] Maleic anhydride grafted POE has elasticity, compatibility, etc.

[0020] Maleic anhydride grafted EAA has better environmental stress cracking, compatibility and toughness, and ethylene-butyl acrylate-glycidyl methacrylate copolymer has better compatibility and toughening effect. Therefore, using one or more of maleic anhydride grafted POE, maleic anhydride grafted EAA, and ethylene-butyl acrylate-glycidyl methacrylate copolymer as a compatibilizer has better compatibility and toughening effect, so it can further improve the mechanical properties of PC-ABS automotive interior materials and reduce the possibility of cracking and breakage due to impact.

[0021] In summary, the recycled ABS and recycled ABS added in this application can reduce carbon emissions, making it green and environmentally friendly, and then compounding with ABS and PC to obtain better comprehensive performance. By adding one or more compatibilizers composed of maleic anhydride grafted POE, maleic anhydride grafted EAA, and ethylene-butyl acrylate-methacrylate glycidyl ester copolymer, the compatibility of its raw material system is further improved, making its raw material system structure tight. Then, through the reinforcement of glass fiber, the PC-ABS automotive interior material has better strength, and with the auxiliary effect of other additives, the obtained PC-ABS automotive interior material has better physical properties. Therefore, the produced automotive interior is not prone to damage, cracking, etc. when impacted, which improves its practicality.

[0022] Automobile interior parts generally refer to the car compartment partitions, door trim panels, dashboard assemblies, armrests, carpets and other parts and materials. The above interior parts are only some auxiliary parts, but they have to bear the functions of vibration reduction, heat insulation, sound absorption and sound insulation, and play a very important role in the comfort of the car. Some interior parts require a certain hardness of the material, and are not easy to deform when subjected to force, and are not easy to be damaged or cracked when impacted. Therefore, during emergency braking, due to inertia, it is inevitable that some items in the car will hit the car interior parts due to inertia. Such as the door handles and side walls inside the car.

[0023] The PC-ABS automotive interior material produced by the present application can reduce the possibility of damage and cracking when hit, thereby improving the durability of PC-ABS automotive interior parts.

[0024] Preferably, the weight ratio of maleic anhydride grafted POE, maleic anhydride grafted EAA, and ethylene-butyl acrylate-glycidyl methacrylate copolymer is (3-5):(1-3):1.

[0025] When maleic anhydride grafted POE, maleic anhydride grafted EAA, and ethylene-butyl acrylate-glycidyl methacrylate copolymer are compounded, a synergistic effect is achieved to further improve the comprehensive performance of PC-ABS automotive interior materials, further reduce the possibility of damage and cracking of automotive interior parts when they are impacted, and at the same time, when automotive interior parts are subjected to stress, they are not easily deformed.

[0026] Preferably, the glass fiber has a length of 20-30 μm and a wire diameter of 3-8 μm.

[0027] The above glass fiber length and wire diameter range can be easily mixed with the raw material system of PC-ABS automotive interior materials, so that the raw material system is closely combined, further improving the mechanical strength of PC-ABS automotive interior materials and reducing the possibility of breakage and cracking.

[0028] Preferably, the glass fiber is a modified glass fiber, and the modified glass fiber is composed of the following raw materials in parts by weight:

[0029] Glass fiber 80-100 parts

[0030] Acrylic acid 1-3 parts

[0031] Epoxy soybean oil acrylate 1-5 parts

[0032] 3-8 parts of hydrogen furfuryl methacrylate

[0033] 1-3 parts triisopropylsilyl methacrylate

[0034] Diallyl maleate 0.5-1.5 parts

[0035] Initiator 0.1-0.5 parts

[0036] 10-20 parts of solvent.

[0037] Preferably, the modified glass fiber is prepared by the following method:

[0038] According to parts by weight, acrylic acid, epoxy soybean oil acrylate, furfuryl methacrylate, triisopropylsilyl methacrylate, diallyl maleate, an initiator and 2 / 1 solvent are weighed and mixed evenly, heated to 60-70° C., reacted for 1-3 hours to obtain a copolymer, and then 1 / 2 of the solvent is added to mix with the copolymer, and stirred at a rotation speed of 300-500 r / min for 20-30 minutes to obtain a copolymer emulsion; then glass fiber is added to the copolymer emulsion and mixed evenly to obtain a blend, the blend is heated to 105-115° C., vacuum distilled to remove the solvent, and solidified to obtain a modified glass fiber.

[0039] Epoxidized soybean oil acrylate is prepared by the ring-opening reaction of acrylic acid and soybean oil. Therefore, it has the characteristics of acrylic acid and epoxy soybean oil, and has the advantages of low viscosity, good wettability, etc. Furfuryl methacrylate is a polymerization monomer, diallyl maleate is a reaction intermediate, triisopropylsilyl methacrylate is a functional acrylate monomer, and can improve the compatibility of glass fiber with organic matter. Therefore, the present application is compounded by acrylic acid, epoxy soybean oil acrylate, furfuryl methacrylate, triisopropylsilyl methacrylate, and diallyl maleate, and reacts to form a macromolecular complex under the action of an initiator.

[0040] Through the dilution effect of the solvent and high-speed stirring, a polymer emulsion is formed. The polymer emulsion has good film-forming properties, good wettability and good compatibility, so it is easy to wet and disperse the glass fiber, and after solidification, the surface of the glass fiber is coated. After solidification and removal of the solvent, a coating film is formed on the surface of the glass fiber. Therefore, the obtained modified glass fiber is easy to mix with the PC-ABS automotive interior material raw material system, so that the PC-ABS automotive interior material has better mechanical properties. Therefore, the produced automotive interior parts are not easy to be damaged or cracked when impacted.

[0041] Preferably, the initiator is one or more of tert-butyl perbenzoate, azobisisobutyronitrile, and dibenzoyl peroxide.

[0042] The above initiators can promote the composite copolymerization reaction of reactive monomers such as acrylic acid, furfuryl methacrylate, triisopropylsilyl methacrylate, etc., and the copolymer emulsion formed by cooperating with other raw materials is easy to adhere to the surface of glass fiber, and after removing the solvent and curing, the formed coating film is stably coated on the glass fiber, and the coating film has good compatibility with the raw material system of PC-ABS automotive interior materials, so that the PC-ABS automotive interior materials have better mechanical properties.

[0043] Preferably, the other auxiliary agent is an anti-aging agent and / or a wetting agent.

[0044] By adding anti-aging agents, the anti-aging properties of PC-ABS automotive interior materials can be improved, reducing the possibility of aging and performance degradation. Wetting agents can further promote the processing of the raw material system of PC-ABS automotive interior materials and improve processing efficiency.

[0045] Preferably, the antioxidant is one or more of antioxidant 1010, antioxidant 1076, and antioxidant 168.

[0046] The above antioxidants all play a good antioxidant role, reducing the possibility of aging and other degradation of physical properties after the use of PC-ABS automotive interior materials.

[0047] Preferably, the lubricant is one or more of polyethylene wax, PETS, EBS, and triphenyl phosphate.

[0048] The above wetting agents all play a lubricating role and improve the convenience of processing.

[0049] In a second aspect, the present application provides a method for preparing a PC-ABS automobile interior material containing glass fiber, comprising the following steps:

[0050] ABS, PC, recycled ABS, recycled PC, glass fiber, compatibilizer and other additives are weighed and mixed evenly according to weight parts, and then extruded and granulated to obtain automobile interior materials.

[0051] The PC-ABS automotive interior material prepared by the above method can not only reduce carbon emissions and be green and environmentally friendly, but also enable the PC-ABS automotive interior material to obtain better physical properties. The resulting automotive interior material is less likely to be damaged or cracked when impacted, thereby improving its practicality.

[0052] In summary, this application has the following beneficial effects:

[0053] 1. The recycled ABS and recycled ABS added in this application can reduce carbon emissions and make it green and environmentally friendly, and then compound with ABS and PC to obtain better comprehensive performance. Then, by adding one or more compatibilizers composed of maleic anhydride grafted POE, maleic anhydride grafted EAA, and ethylene-butyl acrylate-glycidyl methacrylate copolymer, the compatibility of its raw material system is further improved, making its raw material system structure compact.

[0054] The PC-ABS automotive interior material has better strength through the reinforcement of glass fiber, and with the assistance of other additives, the PC-ABS automotive interior material has better physical properties. Therefore, the automotive interior produced is not easy to be damaged or cracked when impacted, which improves its practicality.

[0055] 2. The present application is compounded by acrylic acid, epoxy soybean oil acrylate, furfuryl methacrylate, triisopropylsilyl methacrylate, and diallyl maleate, and reacts to form a macromolecular complex under the action of an initiator.

[0056] Through the dilution effect of the solvent and high-speed stirring, a polymer emulsion is formed. The polymer emulsion has good film-forming properties, good wettability and good compatibility, so it is easy to wet and disperse the glass fiber, and after solidification, the surface of the glass fiber is coated. After solidification and removal of the solvent, a coating film is formed on the surface of the glass fiber. Therefore, the obtained modified glass fiber is easy to mix with the PC-ABS automotive interior material raw material system, so that the PC-ABS automotive interior material has better mechanical properties. Therefore, the produced automotive interior parts are not easy to be damaged or cracked when impacted. DETAILED DESCRIPTION
