preparation example Construction

[0030] A kind of preparation method of the macromolecule plasticizer based on waste oil, wherein, comprises the following steps:

[0031] Step 1, washing, decolorizing, filtering, absorbing, and sterilizing the waste oil to obtain purified waste oil whose main chemical composition is unsaturated fatty acid glyceride;

[0032] Step 2, the purified waste oil obtained in step 1 and high polymerization activity monomer, glass transition temperature regulating monomer and PVC similar solubility parameter monomer are mass ratio 5~100: 5~20: 0~100: 0~50 Mix to obtain a mixed solution, add an initiator with a mass ratio of 0% to 15% to the mixed solution, react at a temperature of 0°C to 150°C, and undergo conventional free radical or living free radical polymerization for 1 hour After 10 hours, a macromolecular plasticizer based on waste oil was obtained.

[0033] In an embodiment, the initiator is azobisisobutyronitrile, azobisisoheptanonitrile, dibenzoyl peroxide, dicumyl peroxide...

Embodiment 1

[0046] Add 100 g of ethyl acetate, 100 g of purified waste oil, 10 g of styrene, 50 g of butyl acrylate, 25 g of methyl methacrylate and 10 g of diphenyl peroxide into a three-necked flask with a heating and stirring device. Formyl, after mixing evenly, gradually increase the system temperature to 70°C, after 7 hours of heat preservation reaction, raise the system temperature to 78°C, continue the heat preservation reaction for 2 hours, then cool the system temperature to 40°C, to obtain waste oil based A solution-polymerizable macromolecular plasticizer.

Embodiment 2

[0048] Add 80 g absolute ethanol, 20 g purified water, 100 g purified waste oil, 25 g styrene, 100 g n-octyl acrylate, 50 g methyl acrylate and 20 g Ammonium persulfate, after mixing evenly, gradually raise the system temperature to 75°C, after 8 hours of heat preservation reaction, raise the system temperature to 80°C, continue the heat preservation reaction for 2 hours, then cool the system temperature to 40°C, that is, the trench-based Precipitation polymerization macromolecule plasticizer of oil.

Abstract

The invention discloses a preparation method of macromolecule plasticizer based on recycled cooking oil, which is characterized in that the purified recycled cooking oil is copolymerized with monomers with polyvinyl chloride (PVC) and similar solubility parameters in a radical grafting way, the glass-transition temperature of a material is adjusted through the molecular design, so that the non-transference macromolecule plasticizer which is applicable to the PVC is obtained. Compared with the traditional plasticizer such as dioctyl phthalate (DOP), the macromolecule plasticizer has the advantages of no volatilization, no transference, low cost, durability and stability of plasticizing property and the like. The macromolecule plasticizer based on the recycled cooking oil can be widely used in the field of semi-hard or soft PVC composite materials such as an oil-resisting and heat-resisting PVC cable, a gasket, artificial leather and the like.

Description

technical field [0001] The invention relates to the technical field of preparation and modification of functional polymer materials, in particular to a preparation method of a waste oil-based macromolecule plasticizer. Background technique [0002] my country is a big country in the production and consumption of edible oil. The annual consumption of edible oil has reached 21 million tons, and during its use, nearly 8 million tons of waste oil (mainly including kitchen hog oil and commercial frying oil) are produced every year. , the so-called "waste oil". At present, the existence of such a huge amount of waste oil has caused a huge impact on the living environment and health of people. On the one hand, the random discharge of waste oil is gradually eroding the urban sewer system necessary for our daily life, which brings inconvenience to people's life and increases the burden on urban sewage treatment enterprises; Driven by rich economic interests, waste oil is simply filt...
