Embodiment 1

[0027] A preparation method for waste oil-based water-based paint, comprising the following steps:

[0028] (1) Use solid-liquid separation technology to obtain liquid waste oil, then wash the liquid waste oil with deionized water, repeat the operation 5-10 times until the water phase is transparent and colorless, collect the oil phase layer after liquid separation, and then wash with absolute ethanol Wash the oil phase layer several times until the ethanol solution after washing is transparent and colorless, separate the waste oil and the ethanol solution, and add hydrogen peroxide to the obtained waste oil for several times until the waste oil is light yellow transparent and clear liquid, that is, the purified waste oil Oil;

[0029] (2) Under normal temperature conditions, mix 100g deionized water, 0.3g sodium bicarbonate, 1.5g sodium lauryl sulfate, 1g OP-10, 0.1g polyvinyl alcohol, 1g potassium persulfate, 0.5g sodium bisulfite , 50g of purified waste oil, 25g of methyl ...

Embodiment 2

[0032] A preparation method for waste oil-based water-based paint, comprising the following steps:

[0033] (1) Use solid-liquid separation technology to obtain liquid waste oil, then wash the liquid waste oil with deionized water, repeat the operation 5-10 times until the water phase is transparent and colorless, collect the oil phase layer after liquid separation, and then use methanol several times Wash the oil phase layer until the washed methanol solution is transparent and colorless, separate the waste oil and the methanol solution, and add montmorillonite to the obtained waste oil several times until the waste oil is light yellow transparent and clear liquid, that is, the purified waste oil Oil;

[0034] (2) Under normal temperature conditions, 100g deionized water, 0.2g EDTA, 1.2g sodium lauryl sulfate, 0.8g NP-10, 0.2g polyvinyl alcohol, 1g hydrogen peroxide, 0.5g sodium bisulfite, Add 45g of purified waste oil, 27.5g of methyl methacrylate, and 27.5g of butyl acryla...

Embodiment 3

[0037] A preparation method for waste oil-based water-based paint, comprising the following steps:

[0038] (1) Use solid-liquid separation technology to obtain liquid waste oil, then wash the liquid waste oil with deionized water, repeat the operation 5-10 times until the water phase is transparent and colorless, collect the oil phase layer after liquid separation, and then use isopropanol Wash the oil phase layer several times until the washed isopropanol solution is transparent and colorless, separate the waste oil and the isopropanol solution, and add activated carbon to the obtained waste oil several times until the waste oil is light yellow transparent and clear liquid. That is to obtain purified waste oil;

[0039] (2) Under normal temperature conditions, 100g deionized water, 0.1g ammonium bicarbonate, 1.2g sodium dodecylsulfonate, 0.8g NP-10, 0.3g hydroxycellulose, 0.8g potassium persulfate, 0.4g sulfite Sodium bisulfate, 40g of purified waste oil, 30g of methyl meth...

Abstract

The invention discloses a preparation method of an illegal-cooking-oil-base water-based paint, which comprises the following steps: (1) preparing purified illegal cooking oil; (2) sequentially adding deionized water, a pH regulator, an emulsifier, a dispersing agent, an initiator, the purified illegal cooking oil and acrylate into a reaction kettle to prepare an illegal cooking oil pre-emulsified liquid; and (3) adding deionized water, a tackifier, a thickener and an ultraviolet absorbent into the illegal cooking oil pre-emulsified liquid to obtain the illegal-cooking-oil-base water-based paint. The preparation method is simple to operate, and has the advantages of wide raw material sources and low cost. The coated film has favorable adhesiveness for external wall substrates of mortar and the like. The coating has the advantages of low peeling tendency, no crack, high strength, favorable toughness and the like. The paint can be widely used for decorating various external walls.

Description

technical field [0001] The invention belongs to the field of preparation and modification of functional polymer materials, and in particular relates to a preparation method of waste oil-based water-based paint. Background technique [0002] Waste oil is a common name for kitchen waste oil, also known as swill oil, which generally refers to the edible oils and fats that are discarded and discharged after food processing in the catering industry and family kitchens. With the rapid development of my country's catering industry, the amount of waste oil produced is also increasing, and its disposal is becoming more and more troublesome. Some restaurants reappear waste oil on the dining table in order to profit from it. Long-term consumption of waste oil may cause cancer, which is extremely harmful to the human body. [0003] The patent application number is 200510029409.7 "Processing Method of Catering Waste Oil" and the patent application No. 200710090972.4 "Recovery and Purifi...
