Embodiment 1

[0040] 1) Epoxidized soybean oil winterization treatment

[0041] The epoxidized soybean oil was cooled to 9°C with a winterization rate of 3°C / h in the early stage, 0.2°C / h in the late stage, and 6°C in the later stage. The crystal growth time was 15h, and the stirring speed was 3rpm. After filtration and separation, the winterized epoxidized soybean oil was obtained, and the epoxy value of the winterized epoxidized soybean oil was tested to be 6.6%.

[0042] The winterization rate of epoxy hog oil methyl ester is 4°C / h in the early stage, and the temperature is lowered to 9°C, and the winterization rate in the later stage is 0.5°C / h, and the temperature is dropped to 6°C, the crystal growth time is 10h, and the stirring speed is 5rpm. After filtration and separation, the winterized epoxy hog oil methyl ester was obtained, and the epoxy value of the winterized epoxy hog oil methyl ester was tested to be 5.6%.

Abstract

The invention provides a low-odor non-toxic non-benzene environment-friendly composite plasticizer, and the plasticizer comprises the following components in percentage by mass: 20 to 80% of cyclohexane diformate; 0 to 20% of winterized or unwinterized epoxy grease; 10 to 50% of winterized epoxy fatty acid methyl ester; 0 to 50% of citrate; 0 to 5% of an antioxidant; 0 to 5% of a deodorant; and the sum of the mass percentages of all the components is 100%. According to the low-odor non-toxic non-benzene environment-friendly composite plasticizer disclosed by the invention, winterized epoxy grease and epoxy fatty acid methyl ester are compounded into a plasticizer system, so that the low-odor non-toxic non-benzene environment-friendly composite plasticizer has the characteristics of low odor, high addition amount, precipitation resistance, good heat-resistant and oxygen-resistant stability, lower cost and the like. Through the composite oxidizing agent and the deodorant, the plasticizing and stabilizing integrated effect is formed, and then the application value is improved.

Description

technical field [0001] The invention belongs to the technical field of environment-friendly plasticizers, and in particular relates to a low-odor, non-toxic, non-benzene environment-friendly composite plasticizer. Background technique [0002] Cyclohexane dicarboxylate plasticizer is a colorless, transparent, almost odorless, new type of non-benzene environment-friendly plasticizer, which can be widely used in sensitive soft PVC products such as toys, food packaging, and medical supplies. However, because its price is more expensive than ordinary ortho-benzene or p-benzene plasticizers, it still cannot be widely promoted at present. [0003] Compared with traditional plasticizers such as phthalate plasticizers, citric acid esters have the advantages of environmental protection and non-toxicity and are used in medicine, food and other fields. However, due to the high volatility and large migration of the products, Insufficient supply of raw materials and high prices limit it...
