Detailed Description
In order that the invention may be more readily understood, reference will now be made to the following more particular description of the invention, examples of which are set forth below. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. These embodiments are provided so that this disclosure will be thorough and complete. The various starting materials used in the examples are, unless otherwise indicated, conventional commercial products.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
The numerical values set forth in the examples of the present invention are approximations, not necessarily values. All values within the error range may be included without limiting to the specific values disclosed in the embodiments of the present invention, where the error or experimental conditions allow.
The numerical ranges disclosed in the examples of the present invention are intended to indicate the relative amounts of the components in the mixture and the ranges of temperatures or other parameters recited in the other method examples.
The embodiment of the invention provides a polymer material which is polymerized by the following components in parts by weight:
PBS 10-40％；
PLA 20-40％；
PBIAT 5-20％；
5-30% of inorganic filler;
0.2 to 0.5 percent of chain extender;
0.2 to 0.5 percent of coupling agent.
Specifically, in a preferred embodiment, the inorganic filler is an inorganic reinforcing filler. The filler is a solid additive for improving the performance of the composite material and reducing the cost, and unlike the reinforcing material, the filler is in a granular form, so that the reinforcing material in a fibrous form is not used as the filler. The addition of the filler can play a role in improving the strength, reducing the linear expansion coefficient, improving the electric conductivity coefficient, improving the weather resistance, improving the surface gloss, improving the acoustic performance, increasing the viscosity, reducing the cost and the like.
In a preferred embodiment, the inorganic reinforcing filler is talc. The talcum powder is added into the polymer, so that the rigidity of the polymer can be improved, the dimensional stability is improved, the high-temperature creep of an additive plastic part is prevented, and the turnover frequency of molding can be increased. The modified talcum powder can also increase the tensile strength and impact strength of a plastic part. The addition of the talcum powder is helpful for improving the melt strength of the plastic parts, and can also be used as a regulator of melt viscosity. The talcum powder has smaller grain diameter, can be used as a crystal nucleus and has certain nucleating effect.
It should be noted that experimental data show that talc increases the crystallization rate of PLA when added in an amount of 1% to 5%, but decreases the crystallization rate when added in an amount of more than 10%. The talcum powder is white or light yellow in color, has a refractive index similar to that of PVC, and can be used as a filler for light-colored and semitransparent plastic products. And the talcum powder also has various advantages, such as low price, acid and alkali resistance, good heat resistance and the like. It can also interact with PLA and other polymers to nucleate and therefore produce better results overall with the polymeric material of the present invention.
Furthermore, the content of the inorganic filler in the polymer material is 30%, and the characteristics of acid and alkali resistance, strength, heat resistance and the like of the polymer material can be enhanced by increasing the content of the inorganic filler. However, if added too much, this can result in processing difficulties due to too high a viscosity to allow efficient stirring. Therefore, the content of the selected inorganic filler is 30%, so that the processing feasibility is considered while the properties such as strength, hardness and the like are ensured.
In a preferred embodiment, the chain extender is at least one of 1, 4-butanediol, 1, 6-hexanediol, glycerol, trimethylolpropane, diethylene glycol, triethylene glycol, neopentyl glycol, sorbitol, diethylaminoethanol MOCA, ethylenediamine, N-dihydroxy (diisopropyl) aniline, hydroquinone bis (β -hydroxyethyl) ether. These are common chain extenders, which are compounds containing active hydrogen and polymer monomer end group prepolymers to cause the molecular chain to be diffused and extended, thereby realizing the curing and forming of resin and changing the heat resistance, hardness and elasticity of the resin. The type of the chain extender and the content of the chain extender can be changed according to different proportions.
In a preferred embodiment, the coupling agent is at least one of a silane coupling agent and a titanate coupling agent. The coupling agent is used in rubber industry, can improve the wear resistance and aging resistance of products such as tires, rubber plates, rubber tubes, rubber shoes and the like, and can reduce the dosage of NR, thereby reducing the cost. The coupling agent in the composite material can react with certain groups on the surface of the reinforcing material and also react with matrix resin to form an interface layer between the reinforcing material and the resin matrix, and the interface layer can transfer stress, so that the bonding strength between the reinforcing material and the resin is enhanced, the performance of the composite material is improved, other media can be prevented from permeating into the interface, the interface state is improved, and the aging resistance, the stress resistance and the electrical insulation performance of a product are facilitated. The polymer can further improve the material performance through a coupling agent, so that the polymer further exerts the advantages of elasticity, weather resistance, toughness and the like.
According to another aspect of the embodiments of the present invention, there is provided a high temperature resistant plastic, which is processed from the polymer material. In a preferred embodiment, the processing mode of the high-temperature resistant plastic is extrusion molding. Extrusion molding is also called extrusion molding in plastic processing, and extrusion molding in a non-rubber extruder processing by using hydraulic press pressure on a die per se is called extrusion. The method is a processing method for manufacturing various cross-section products or semi-products by continuously passing materials through a machine head while being heated and plasticized and being pushed forward by a screw under the action of a charging barrel and the screw of an extruder. The polymer material has good high-temperature resistance, and the hard plastic has good biocompatibility and better biodegradability, so that the polymer material is particularly suitable for being applied to biology, medical instruments and catering materials, such as heat-resistant tableware, cutlery, medical instruments with high requirements on biocompatibility and biomaterials.
In another aspect, an embodiment of the present invention provides a method for preparing the polymer material, as shown in fig. 1, including the following steps:
s01: premixing the components in the formula amount;
s02: heating and polymerizing the mixed components;
s03: and cooling to obtain the polymer material.
Specifically, in step S01, the mixing manner includes at least one of ultrasonic, stirring, shaking, centrifuging, ball milling, and the like.
Specifically, in the step S02, the heating manner of the heating polymerization is to gradually increase the temperature and then keep the temperature constant, and the heating temperature is 150-.
The embodiment of the invention also provides an application of the high-temperature resistant plastic in the aspect of the high-temperature odor-free suction pipe on the other hand. Due to good thermal stability and thermal rigidity, the properties can be kept unchanged and not decomposed at higher temperature, so that the straw can be applied to a non-odor straw.
The polybutylene succinate (PBS) adopted by the embodiment of the invention is a polymer with good biodegradability, and compared with biodegradable plastics such as polylactic acid, polyhydroxyalkanoate and polycaprolactone, the polybutylene succinate (PBS) has the characteristics of excellent mechanical property, good heat resistance and thermal deformation temperature close to 100 ℃. Therefore, the polymer product provided by the scheme has more excellent heat resistance and mechanical property. The main auxiliary material of the polymer is PLA which is a polymer with good degradability, the content of the residual organic raw materials of the PLA after degradation is low, or inorganic materials which can not cause environmental pollution are doped, or a coupling agent and a chain extender which can be reacted after polymerization reaction are added, so that the integral polymer material has good performance and higher degradation speed, is more thoroughly degraded, has less harmful residues, and is a green and environment-friendly material. In addition, the polymer also comprises PBIAT, compared with the PBIAT material, the PBIAT material has low carbon footprint and faster natural decomposition speed in soil. In addition, because PBIAT is stronger than PBAT, thinner, tougher products than PBAT can be made with less raw material. Therefore, the polymer product has wider application range and more excellent performance. In addition, both PBIAT and PLA have good biocompatibility, so the polymer material provided by the invention has good application prospect in the aspect of biological materials. Due to good biological affinity, the polymer material can be applied to biological materials, catering and medical appliances. In addition, a large amount of inorganic filler is added into the polymer material, so that the polymer material has high hardness and strength and has the characteristics of wear resistance, weather resistance and high melting point. Compared with common plastics, the plastic has higher working temperature and wider application range. In europe, disposable plastic bags can only be used if the biomass content exceeds 50%. PBS and PLA with high biomass content are beneficial to entering European market. Most of the most important raw materials for forming the polymer material in the scheme are cheap and easy to obtain, so that the production cost is greatly reduced. It should be noted that no PLA may be added, i.e. the PLA content in the formulation is zero, and good technical effects can be obtained.
