Embodiment 1

[0043] Embodiment one, the raw material formula and weight of use are: 18 parts of T-10 or fatty alcohols or alkylphenols as surfactant, 20 parts of ethanol or Virahol or mixed propanol or mixed butanol or n-butanol Or methanol or isobutanol as alcohol solvent, 18 parts of dibutyl phthalate or dioctyl phthalate or dibutyl sebacate or dioctyl sebacate or dioctyl adipate or Diisooctyl phthalate or dicarboxylic acid phthalate or glycerol triacetate or butyl epoxy fatty acid as plasticizer, use 44 parts of water as dilution. Its production process is as follows:

[0044] 1. Dilute one of the above-mentioned surfactants (i.e. 18 parts of T-10 or fatty alcohols or alkylphenols) with an appropriate amount of water (some surfactants, such as T-10, are diluted It must be heated to 30-60 degrees Celsius to facilitate the dissolution of the surfactant) and then poured into the reaction kettle;

[0045] 2. Add one of the above-mentioned plasticizers into the reactor (that is, 18 parts o...

Embodiment 2

[0048] Embodiment two, the raw material formula and weight used are: 16 parts of dioctyl phthalate as plasticizer, 8 parts of ethanol and 8 parts of isopropanol as alcohol solvent, 16 parts of T-10 as surfactant, Add 4 parts of phosphoric acid, 8 parts of ethylene glycol monobutyl ether as an ether solvent, 10 parts of 6501—a detergent aid, and use 30 parts of water for dilution. Its production process is as follows:

[0049] 1. Pour 4 parts of phosphoric acid into the reaction kettle, add an appropriate amount of water to dilute the phosphoric acid;

[0050] 2. Dilute 16 parts of surfactant - T-10 with water (heat the water to 30-60 degrees Celsius when diluting) and pour it into the reaction kettle;

[0051] 3. Add 16 parts of dioctyl phthalate into the reactor and stir, while controlling the temperature in the reactor at 15-25 degrees Celsius for 30 minutes;

[0052] 4. Dilute 10 parts of washing aid - 6501 with an appropriate amount of water and mix it with 8 parts of et...

Embodiment 3

[0057] Embodiment 3, a formula of a decolorizing agent for a barrel of a plastic processing machine, the weight percentages of each material are respectively: surfactant accounts for 3%, alcohol solvent accounts for 3%, plasticizer accounts for 3%, and the rest is water .

Abstract

The invention relates to a formula of a charging barrel decolorizing agent of a plastic processing machinery which is high in washing efficiency and little in material use and a preparation method thereof; the invention comprises a plasticizer, an alcoholic solvent, a surfactant and water, wherein, the weight percentages of the materials respectively are: the surfactant: 3 to 38 percent; the alcoholic solvent: 3 to 38 percent; the plasticizer: 3 to 38 percent and the rest is water. The surfactant plays the roles of catalyzing and sterilization, the alcoholic solvent has the functions of disinfection and sterilization and dispersing filths, and water is used for diluting. When in making, all the components are diluted by water and mixed and reacted according to a certain order, and then the charging barrel decolorizing agent is made. A certain amount of phosphoric acid, esters solvent and detergent can be added on the basis of the components.

Description

technical field [0001] The invention relates to a formula of a decolorizing agent and a manufacturing method thereof, in particular to a formula and a manufacturing method of a barrel decolorizing agent of a plastic processing machine. Background technique [0002] Existing plastic processing machinery—such as plastic injection machines, etc., before changing the color of the product produced, the barrel in the plastic processing machine or the screw in the barrel must be cleaned to prevent the last batch of The remaining plastics of different colors affect the color of the product to be produced; the cleaning method is to put a large amount of raw materials of the product to be produced into the barrel and heat it, so that the residue remains in the barrel or in the barrel and the screw. The residual material of the plastic processing machine is injected or discharged (the principle is to dilute the color pigment in the barrel or screw) until the color of the injected or di...
