Problems solved by technology

[0004] 1. It may cause gender confusion in children, including shortened genitals and indistinct sexual characteristics;
[0005] 2. Although it is currently impossible to confirm whether it is carcinogenic to humans, it will cause carcinogenic reactions to animals;
[0006] 3. Phthalates may affect the secretion of hormones in fetuses and infants, cause hormone imbalance, and lead to precocious puberty in children
However, there is a problem with the compatibility of epoxy soybean oil and epoxy fatty acid methyl ester with PVC. If the amount added exceeds 10%, problems such as oil leakage and blooming will occur, which will affect the quality and function of plastic products. Therefore, it can only be used As an auxiliary plasticizer, it cannot completely replace phthalate plasticizers
[0011] Citrate triester plasticizers have good compatibility with PVC and can be used as the main plasticizer to completely replace phthalate plasticizers. However, the output is limited and it is impossible to meet such a huge market demand. , and the production cost is high, it cannot compete with phthalate plasticizers in price

example 1

[0018] With epoxy soybean oil, epoxy soybean fatty acid methyl ester, epoxy pentaerythritol tetraoleate and acetyl tributyl citrate as raw materials, according to the proportioning shown in Table 1, the plasticizer is prepared, and then mixed with PVC resin, with DOP is used as the control, and the performance test is carried out. The test results are shown in Table 2. T50% is the temperature at which the plasticizer loses 50% of its weight, and the higher the T50%, the better the thermal stability. Plasticizing effect and compatibility with PVC are based on DOP as a reference sample.

[0034] With epoxy soybean oil, epoxy soybean fatty acid methyl ester, epoxy pentaerythritol tetrasoybean fatty acid ester and dioctyl terephthalate as raw material, operate according to the experimental method identical with example 1, obtain and example 1 similar result. It shows that after replacing pentaerythritol tetraoleate with epoxy pentaerythritol tetrasoybean fatty acid ester and acetyl tributyl citrate with dioctyl terephthalate, the obtained formula can also replace DOP as a plasticizer.

example 3

[0036] With epoxy cottonseed oil, epoxy cotton oil fatty acid methyl ester, epoxy pentaerythritol tetracotton oil fatty acid ester and tributyl citrate as raw material, operate according to the experimental method identical with example 1, obtain and example 1 similar result. It shows that epoxidized cottonseed oil is used to replace epoxidized soybean oil, epoxidized cotton oil fatty acid methyl ester is used to replace epoxidized soybean fatty acid methyl ester, epoxy pentaerythritol tetracotton oil fatty acid ester is used to replace pentaerythritol tetraoleate, tributyl citrate After the ester replaces acetyl tributyl citrate, the resulting formulation can also replace DOP as a plasticizer.

Abstract

The invention belongs to the technical field of a novel material, and particularly relates to a biological environment-friendly plasticizer capable of completely replacing dioctyl-phthalate (DOP). The plasticizer is prepared from the following ingredients by mass percent in a mixing manner: 15-50% of epoxy vegetable oil, 10-50% of epoxidized fatty acid methyl ester, 0-50% of epoxy fatty acid polyol ester, and the balance of cold resistant plasticizer. The biological environment-friendly plasticizer is reasonable in formula, low in cost, low in melting temperature, and strong in weather fastness, all production raw materials are from renewable resources, and cheap and available, the production cost can be saved, the capacity is greatly improved, the product can be completely biodegraded, and the biological environment-friendly plasticizer is free of poison and harm to the environment, and can certainly replace the traditional DOP plasticizer on the market in the future.

Description

technical field [0001] The invention relates to a bio-based environment-friendly plasticizer which can completely replace DOP, and belongs to the technical field of new materials. Background technique [0002] Plasticizer is a polymer material additive widely used in industry, and it is one of the plastic additives with the largest production and consumption in the world. Adding this substance in plastic processing can enhance its flexibility and facilitate processing. Plasticizers can be divided into main plasticizers and auxiliary plasticizers. Plasticizers are non-solvent plasticizers if their molecules can only insert into the amorphous regions of the polymer, so-called co-plasticizers. A plasticizer is a solvent-borne plasticizer if its molecules are able to insert into both the amorphous and the crystalline regions of the polymer, so-called primary plasticizers. By 2012, the total global plasticizer production capacity is about 7.5 million tons / year, and the global p...
