Description

Technical Field

[0001] This invention belongs to the field of polymer nanocomposite materials technology, specifically relating to an environmentally friendly green bio-based material and its preparation method. Background Technology

[0002] Polylactic acid (PLA), a fully biodegradable bio-based polymer, possesses excellent mechanical strength and elastic modulus. It can also be molded using various conventional processing methods, such as extrusion, spinning, biaxial stretching, blow molding, and injection molding. Furthermore, lactic acid, the raw material for PLA production, can be obtained from biomass such as starch, cellulose, and lignin through microbial fermentation, offering better renewability compared to petrochemical resources. Therefore, it has great potential to replace general-purpose and engineering plastics. However, compared to petrochemical-based polymers, its extremely low impact resistance and heat resistance have become bottlenecks to its widespread application, making it difficult to truly replace petrochemical-based polymers in large quantities in the fields of general-purpose and engineering plastics. Therefore, to overcome these shortcomings, numerous research efforts have been conducted on the physical modification of PLA, all aiming to address the challenge of PLA's widespread replacement of petrochemical-based polymers.

[0003] However, in the publicly available field of bio-based polymer materials, no bio-based polymer material has been found that simultaneously possesses high impact resistance and high heat resistance. Therefore, the bio-based properties must be partially sacrificed by reducing the polylactic acid (PLA) content and alloying it with a petrochemical-based polymer material possessing high impact resistance and high heat resistance to improve the impact and heat resistance of PLA. Polycarbonate is the best choice among these materials due to its excellent impact and heat resistance.

[0004] For example, CN201410586591.5 discloses a high-impact, high-bio-based engineering plastic molding article and its preparation method. This engineering plastic molding article is composed of 70-100 parts by weight of polylactic acid resin, 0-30 parts by weight of polycarbonate resin, 0.2-0.6 parts by weight of compatibilizer, 2-6 parts by weight of impact modifier, and 0.2-0.6 parts by weight of crystallizing nucleating agent, forming a high-impact, high-bio-based engineering plastic. The corresponding product has a very high notched impact strength (37.5~69.2kJ / m). 2 The overall performance is quite good, but the use of compatibilizers increases the melt viscosity of the system, reducing the production efficiency of the extruder. At the same time, the presence of impact modifiers will reduce the strength and heat resistance of the material to some extent. In addition, the higher number of components results in higher costs. Summary of the Invention

[0005] This invention aims to at least partially solve one of the technical problems in related technologies. Therefore, the main objective of this invention is to provide an environmentally friendly green bio-based material with high production efficiency and excellent impact resistance, mechanical strength, and heat resistance. This invention also provides a method for preparing this environmentally friendly green bio-based material.

[0006] The objective of this invention is achieved through the following technical solution:

[0007] In a first aspect, an environmentally friendly green bio-based material comprises the following components by weight: 100 parts of base resin, 0.1-30 parts of multi-effect nano-active particles, and 0.1-0.6 parts of crystal nucleating agent; wherein the base resin comprises a mixture of polylactic acid resin and polycarbonate resin in a mass ratio of (1-10):(1-5).

[0008] Furthermore, it includes the following components by weight: base resin: 100 parts, multi-effect nano-active particles: 0.5-5 parts, crystallizing nucleating agent: 0.3-0.5 parts.

[0009] In some specific embodiments, the polycarbonate resin is at least one of bisphenol A type polycarbonate or isosorbide type polycarbonate.

[0010] In some specific embodiments, the multi-effect nanoparticles are prepared by a homogeneous precipitation method in an ethanol-water medium using a silicate precursor and a multi-effect active grafting agent.

[0011] Furthermore, the silicate precursor is composed of tetraethyl orthosilicate and any one of N-β-(aminoethyl)-γ-aminopropyltrimeth(eth)oxysilane, aminopropyltrimeth(eth)oxysilane, N-β-(aminoethyl)-γ-aminopropylmethyldimeth(eth)oxysilane, and 3-glycidyl etheroxypropyltrimeth(eth)oxysilane in a molar ratio of 99.9–70:0.1–30.

[0012] Furthermore, the multi-functional active grafting agent is composed of any one of the following: (meth)acrylate-(meth)acrylate hydroxyethyl ester copolymer and (meth)acrylate-styrene copolymer, or (meth)acrylate-phenyl acrylate copolymer, or (meth)acrylate-(meth)acrylate isosorbide ester copolymer.

[0013] In some specific embodiments, the nucleating agent is at least one of aromatic amides, aryl phosphonates, and talc.

[0014] Furthermore, the aromatic amide is N 1 N 3 N 5 -Tricyclohexylpyromellitic acid, N 1 N 3N 5 -3-tert-butylpyromellitic acid, N 1 N 3 N 5 -Triphenylpyromellitic acid, N 1 N 3 N 5 - At least one of tribenzylpyromellitic acid, dibenzoyl hydrazine octanoate, or dibenzoyl hydrazine sebacate; wherein the aryl phosphonate is at least one of sodium substituted aryl phosphonate, potassium substituted aryl phosphonate, zinc substituted aryl phosphonate, calcium substituted aryl phosphonate, aluminum substituted aryl phosphonate, or magnesium substituted aryl phosphonate.

[0015] Secondly, a method for preparing the aforementioned environmentally friendly green bio-based material includes the following steps:

[0016] (1) Dry polylactic acid resin, polycarbonate resin, multi-effect nano-active particles and crystallizing nucleating agent thoroughly in a vacuum oven at 80°C;

[0017] (2) According to the formula requirements, the dried polylactic acid resin, polycarbonate resin, multi-effect nano-active particles and crystallizing nucleating agent are added to the high-speed mixer and mixed evenly. Then, the mixture is melt-extruded and granulated by a twin-screw extruder at 190-230℃ to obtain environmentally friendly green bio-based materials.

[0018] Compared with the prior art, the present invention has at least the following advantages:

[0019] The environmentally friendly bio-based material provided by this invention is prepared by creating multi-effect nano-active particles with a large number of hydroxyl, phenyl, or isosorbide cyclic groups on the surface, and then adding them to a base resin. The hydroxyl groups in the polymer layer on the surface of the multi-effect nano-active particles can form strong hydrogen bonds with the ester groups in the polylactic acid molecular chain, while the phenyl or isosorbide cyclic groups can form strong van der Waals interactions with the phenyl or isosorbide cyclic groups in the polycarbonate molecular chain. This significantly improves the interfacial adhesion between the polylactic acid resin matrix and the polycarbonate resin dispersed phase, resulting in better impact toughness of the composite material. At the same time, because the polymer on the surface of the multi-effect nano-active particles has a relatively low molecular weight, low viscosity, and low melting temperature, it can effectively reduce the friction at the phase interface during melt processing, thus giving the bio-based material good flowability and ensuring high production efficiency. In addition, due to the inherent reinforcing properties of the multi-effect nano-active particles, their addition can also significantly improve the mechanical strength and heat resistance of the bio-based material, greatly improving its overall performance.

[0080] Performance testing:

[0081] This application conducted performance tests on the environmentally friendly green bio-based materials prepared in Examples 1-6 and Comparative Examples 1-4, and the results are shown in Table 1:

[0082] Table 1 Performance tests of environmentally friendly green bio-based materials in each embodiment and comparative example

[0083]

[0084] As shown in the performance test data in Table 1, the environmentally friendly green bio-based material provided in this application possesses excellent impact resistance, heat resistance, mechanical strength, and melt flow properties. Data from Example 3 and Comparative Example 1 show that the addition of multi-effect nano-active particles significantly improves the impact strength of the bio-based material and endows it with excellent comprehensive properties.
