Description
Technical Field
The invention relates to a biodegradable material, in particular to a biodegradable material which can not generate dioxin when being combusted.
Background
Polyvinyl Chloride (PVC) currently has a global productivity close to 6,000 ten thousand metric tons, is almost one of the most widely used plastics in the global yield, has the characteristics of acid and alkali resistance, flame retardance, good processability and the like, and is widely applied to the fields of building materials, industrial products, civil products and the like.
However, although the application of pvc is excellent, with the recent environmental awareness, the material cannot be decomposed by the environment and the environmental pollution or human body injury such as Dioxin (or Dioxin) which is a carcinogenic pollutant generated during incineration has been limited.
In order to solve the problem that polyvinyl chloride cannot be decomposed by the environment, the aim of reducing the usage amount of polyvinyl chloride is gradually developed by adding some natural completely decomposed materials, such as starch or plant fiber powder, but the original physical and mechanical properties of polyvinyl chloride are reduced by adding a large amount of natural completely decomposed materials, and even along with the problem of environmental pollution caused by plastic particles derived from the decomposed raw materials, the environmental ecology and the food chain can be changed, so that the absorption of human bodies is finally influenced.
Therefore, there is a need to develop a new material which not only has biodegradable properties, but also does not generate dioxin or has an extremely low content when burned, and can maintain physical properties and mechanical properties of polyvinyl chloride, so as to meet the market demand and achieve environmental protection.
Disclosure of Invention
In order to overcome the defects that the prior polyvinyl chloride material can not be decomposed and incinerated by the environment to generate carcinogenic pollutant dioxin, and the problems that the physical property and the mechanical property are reduced due to the addition of natural completely biodegradable materials, and the like, the invention provides a biodegradable material, which comprises: 100phr Polyvinyl Chloride Powder (PVC); 40 to 160phr of plasticizer; 0.5 to 4phr of enzyme; and the degradation rate of the biodegradable material in an anaerobic environment is more than 90 percent.
Wherein the plasticizer is a plasticizer without benzene rings.
Preferably, the plasticizer is a plasticizer which does not contain benzene rings and has a linear chemical structure.
More preferably, the plasticizer comprises soybean oil.
Wherein the enzyme comprises an ester enzyme.
Preferably, the ester comprises an ester synthesized by inorganic acid and alcohol, an ester synthesized by grease and alcohol, an ester of carboxylic acid chlorinated derivative or a mixture of the three esters.
More preferably, the inorganic acid comprises phosphoric acid or sulfuric acid.
Wherein the biodegradable material further comprises a filler less than 20 phr.
Preferably, the filler comprises calcium carbonate.
As can be seen from the above description, the present invention has the following advantages:
1. the invention achieves the degradation effect through the anaerobic bacteria edible plastic material in the anaerobic environment, so the product prepared by the invention does not degrade in the common environment/the oxygen-containing environment, can maintain good quality, and creates the anaerobic environment to degrade the material when the waste is recovered; compared with the traditional PVC material, the sample of the invention not only contains dioxin with a content lower than the standard, but also has high degradation capability, and the dioxin content in the golden sample after incineration is only one thousandth of the international standard content and is far lower than the internationally specified standard value.
2. The invention utilizes the plasticizer and a small amount of enzyme components to achieve the characteristic of high degradability of the whole plastic material, and because no natural completely decomposed material such as starch or plant fiber powder is added, the physical property or the mechanical property of the product is not reduced, and the invention is a novel and innovative material.

Detailed Description
So that the manner in which the above recited features of the present invention can be understood in detail, a more particular description of the invention, briefly summarized above, may be had by reference to embodiments, some of which are illustrated in the appended drawings.
The present invention provides a biodegradable material comprising:
100phr Polyvinyl Chloride Powder (PVC);
40 to 160phr of plasticizer; and
0.5 to 4phr of an enzyme.
The plasticizer is preferably a plasticizer having no benzene ring in the chemical structure, and more preferably a plasticizer having no benzene ring and a linear chemical structure, such as soybean oil.
The enzyme (or enzyme) is mainly an ester material. The esters include esters of an inorganic acid (e.g., phosphoric acid, sulfuric acid, etc.) and an alcohol, esters of an oil or fat (functional group: RCOOR ") and an alcohol, esters of a chlorinated derivative of a carboxylic acid, and mixtures of the three esters. The combination of the plasticizer and the enzyme can achieve the biological decomposable effect. The term biodegradable in the sense of the present invention means that the product obtained from the material according to the invention, in its entirety (comprising the polyvinyl chloride plastic component), is highly (at least 90%) or even completely degraded over a period of time.
The invention utilizes the degradation mechanism generated by the plasticizer and the ester enzyme which do not contain benzene rings and have linear chemical structures, and mainly adds the plasticizer and the ester enzyme, so that the invention can carry out enzymatic decomposition to induce a large amount of anaerobic edible plastic component materials in the environment, and gradually digest and decompose the anaerobic edible plastic component materials into a plurality of gases, thereby achieving the effect of degradation.
Furthermore, the invention can add 20phr or less of filler, such as calcium carbonate, calcium silicate, calcium sulfate, talcum powder or titanium dioxide, etc., to achieve the effect of reducing cost without influencing the degradation and dioxin generation effects of the invention.
Please refer to table 1 below, which is a relevant test sample parameter to confirm the efficacy of the present invention:
TABLE 1
In the sample No. 1565 of the present invention in table 1, the plasticizer is preferably soybean oil, the enzyme is preferably an ester synthesized by inorganic acid (such as phosphoric acid or sulfuric acid) and alcohol, and further, a stabilizer with 20phr or 1.5 to 5phr of calcium carbonate can be further included as a filling or processing additive, but it is confirmed by the experiment of the present invention that the addition of these filling or processing additives does not affect the degradation and effect of producing dioxin. In addition, the embodiment examples in table 1 are only presented as the best sample effect of the present invention, and are not intended to limit the present invention to include only the embodiment or only the range, and the ranges of the components or other optional components indicated in the present invention have been proved to be effective.
Referring to the following table 2, fig. 1 and fig. 2, the present invention uses the above samples to perform a degradation test in the form of a sheet test sample (each sheet sample has a thickness of 1.15mm and a unit weight of 686g/m2) obtained by an existing film manufacturing process, and performs a degradation test for one year by using an anaerobic biodegradation test of ASTM D5511-12 in an anaerobic environment as a test standard. From the gas content tests in table 2 and fig. 1, the samples of the present invention accumulated the most gas than other groups, which confirmed that the samples 1565 of the present invention had the degradation effect, and the samples of the present invention produced more gas in a certain time than the samples that can be decomposed completely by POSITIVE, which confirmed that the present invention has the function of accelerating the degradation of plastics, while the samples of NEGETIVE and the control group No. 1566 had almost no gas and no sign of degradation. Table 2 and fig. 2 show that the samples 1565 of the present invention have degradation effect for a year, and the degradation rate is nearly 100%, even higher than that of the samples that are completely decomposed by POSITIVE, while the samples neegive and the control 1566 of the present invention are not degraded or have very low degradation rate.
TABLE 2
Furthermore, the sample sheet (sample No. 1565) prepared by the invention in the table 1 is incinerated, the obtained ash is subjected to dioxin detection test by utilizing NIEA M801.13B, the content of dioxin in the ash is more than 1.0ng I-TEQ/g according to the current international regulations, and the test standard is that the dioxin is detected (wherein ng is 10-9 g of Neq, I-TEQ is the international toxicity equivalent of dioxin), but the dioxin and furan in the ash are only detected to be 0.001ng I-TEQ/g which is lower than the international environmental protection standard, so that the ash is an environment-friendly product with excellent quality. Furthermore, the present invention performs the same detection on the neget samples in table 1, i.e. the samples of general all-PVC material, and the detection result is 0.242ng I-TEQ/g measured for dioxin and furan in the ash, which shows that the present invention has the efficacy of reducing the content of dioxin compared with the existing PVC material.
It is noted that in general, the production of dioxin involves the content of dioxin in the sample before combustion, and dioxin in the ash after combustion and exhaust gas from the combustion process. The plasticizer does not contain benzene rings and has a linear chemical structure, so that a large amount of dioxin or derivative pollutants are not generated in ash after combustion. The waste gas in the combustion process is different according to the temperature used in the combustion process, if a low-temperature combustion (250-500 ℃) method is adopted, more dioxin can be generated, and the dioxin can be continuously eliminated by using higher temperature (above 800 ℃) in treatment, namely, the content of the dioxin in the air after combustion can be controlled by the combustion temperature, so that the invention focuses on whether the sample and the ash slag before and after combustion mainly contain excessive dioxin, and the detection proves that the sample and the dioxin in the ash slag are far lower than the international standard.
Please refer to table 3, which shows the physical properties and mechanical properties of the sample 1565 sheet material of table 1. Tests show that the invention still maintains good mechanical properties under the condition of high degradation property, and has small difference compared with common plastic which can not be decomposed.
TABLE 3
The material formula provided by the invention can be applied to manufacturing building materials, industrial products and civil products, and is particularly suitable for manufacturing products of artificial leather due to the elasticity of the materials.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the scope of the present invention, and all other equivalent changes and modifications that do not depart from the spirit of the present invention should be included in the scope of the present invention.
