Example Embodiment

[0057] The second aspect of the present invention provides a preparation method of the degumming composition, which includes the following steps: firstly add limonene and co-solvent into a stirred tank for stirring; then add the remaining raw materials, continue stirring until dissolved, and let stand still Defoaming for 8-12 hours; finally filtered and packaged, ready to go.

[0058] The third aspect of the present invention provides the application of the gel removing composition, which can be applied to aerosols and gel removing liquids.

[0059] When the degumming composition is applied to an aerosol, the raw materials at least include 85-100 parts by weight of the degumming composition, 0.1-0.3 parts of preservatives, and 0.1-0.3 parts of rust inhibitors.

[0060] The aerosol also includes a propellant gas; the amount of the propellant gas is 0.1-0.5 wt% of the degumming composition.

[0061] The water content in the aerosol is less than 800 ppm.

[0062] When the aerosol is at 50...

Example Embodiment

[0066] Example 1

[0067] Example 1 provides a degumming composition, in parts by weight, comprising the following raw materials: 60 parts of D-limonene, 72 parts of unsaturated acid esters, 45 parts of dehydrated solvent oil, 10 parts of dibasic acid esters, 15 parts of co-solvent, 8.6 parts of polyether derivative with amino group;

[0068] The unsaturated acid ester is methyl oleate;

[0069] The de-hydrocarbon solvent oil is selected from Shanghai Huishuo Chemical Co., Ltd. D110 environmentally friendly solvent oil;

[0070] The dibasic acid methyl ester monomers include 3.3 parts of dimethyl succinate, 5 parts of dimethyl glutarate, and 1.7 parts of dimethyl adipate;

[0071] The co-solvent is diethylene glycol butyl ether; CAS is 112-34-5;

[0072] The polyether derivative with amino group is 4-aminobutyraldehyde diethanol.

[0073] The preparation method of the degumming composition includes the following steps: first add limonene and co-solvent into a stirred tank for stirring; ...

Example Embodiment

[0074] Example 2

[0075] The difference between Example 2 and Example 1 is that, in parts by weight, it includes the following raw materials: 50 parts of D-limonene, 50 parts of unsaturated acid esters, 35 parts of dehydrated solvent oil, 5 parts of dibasic acid esters, and auxiliary 10 parts of solvent, 2.5 parts of polyether derivative with amino group;

[0076] The dibasic acid ester includes 1.7 parts of dimethyl succinate, 2.5 parts of dimethyl glutarate, and 0.8 parts of dimethyl adipate.

Abstract

The invention relates to the technical field of cleaning supplies, and in particular to a degumming composition and a preparation method and application thereof. The degumming composition comprises atleast the following raw materials in parts by weight: 45-80 parts of an unsaturated acid ester, 50-70 parts of limonene, 35-50 parts of dehydrocarbon solvent oil, 5-15 parts of a diprotic acid ester,and 10-20 parts of a co-solvent. The degumming composition provided by the invention is safe, environment-friendly, and soft and fragrant in flavor, has a short removal time for a gum, and a high removal rate, and enables the gum to be removed relatively completely. The inventors unexpectedly discover that thermal stability of the degumming composition can be improved by adding an appropriate amount of an amino-containing polyether derivative into the raw materials. The degumming composition can still guarantee excellent degumming efficiency for at least 3 months at the environment of 50 DEGC.

Description

Technical field [0001] The invention relates to the technical field of cleaning products, in particular to a degumming composition and a preparation method and application thereof. Background technique [0002] As the application of adhesives in my country becomes more and more widespread, a large amount of residual glue will also be produced. There will be residual glue in factories, equipment, homes, shops, furniture, automobiles, and public places, such as advertisements, labels, and stickers. , Home decoration, etc. [0003] The main methods for removing waste rubber at home and abroad are solvent method, emulsion method, high-pressure water equipment cleaning, dry ice equipment cleaning and mechanical scrubbing. The raw materials used in solvent and emulsion cleaning are mostly non-environmentally friendly solvents such as tetrachloroethylene, ethyl acetate, etc. These solvents are toxic solvents, which can cause liver damage, dermatitis and eczema, etc., and even death in sev...
