Problems solved by technology

The raw materials used in solvent and emulsion cleaning are mostly non-environmental solvents such as tetrachloroethylene, ethyl acetate, etc. These solvents are toxic solvents, which can cause liver damage, dermatitis, eczema, etc., and even death in severe cases. , causing serious harm to the environment
Although high-pressure water and dry ice cleaning methods are safe and environmentally friendly, and can completely and quickly remove rubber scale, but the initial investment in equipment is large, it is not suitable for popularization
The portable cleaning machine has the problem of incomplete cleaning

preparation example Construction

[0057] The second aspect of the present invention provides the preparation method of the degumming composition, comprising the following steps: firstly adding limonene and co-solvent into the stirred tank for stirring; then adding the remaining raw materials, continuing to stir until dissolved, and standing Defoaming for 8-12 hours; finally filtered and packaged.

[0058] The third aspect of the present invention provides the application of the degumming composition, which can be applied to aerosol and degumming liquid.

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

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

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

[0062] When the aerosol is...

Embodiment 1

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

[0068] The unsaturated acid ester is methyl oleate;

[0069] The dehydrocarbon solvent oil is selected from Shanghai Huishuo Chemical Co., Ltd. D110 environment-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 groups is 4-aminobutyraldehyde diethyl acetal.

[0073] The preparation method of the degumming composition comprises the following steps: first, adding limonene and a cosolvent into a stirring tank for stirring;...

Embodiment 2

[0075] The difference between Example 2 and Example 1 is that, in parts by weight, the following raw materials are included: 50 parts of D-limonene, 50 parts of unsaturated ester, 35 parts of dehydrogenated solvent oil, 5 parts of dibasic acid ester, auxiliary 10 parts of solvent, 2.5 parts of polyether derivatives with amino groups;

[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, in particular to a degumming composition and a preparation method and application thereof. A degumming composition, at least including the following raw materials in parts by weight: 45-80 parts of unsaturated acid ester, 50-70 parts of limonene, 35-50 parts of dehydrocarbon solvent oil, 5-15 parts of dibasic acid ester part, 10-20 parts of cosolvent. The degumming composition provided by the invention is safe and environment-friendly, has a mild and delicate taste, has short degumming time and high degumming rate, and can completely remove the degumming. The inventors unexpectedly found that adding an appropriate amount of polyether derivatives with amino groups to the raw materials can improve the thermal stability of the degumming composition. The degumming composition can guarantee excellent degumming efficiency for at least 3 months under the environment of 50°C.

Description

technical field [0001] The invention relates to the technical field of cleaning supplies, in particular to a degumming composition and a preparation method and application thereof. Background technique [0002] With the application of adhesives in our country more and more widely, a large amount of residual glue will also be produced. There will be residual glue in factories, equipment, homes, shops, furniture, cars and public places that needs to be removed, such as advertisements, labels, stickers , home improvement, etc. [0003] The main methods of removing waste rubber at home and abroad include 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-environmental solvents such as tetrachloroethylene, ethyl acetate, etc. These solvents are toxic solvents, which can cause liver damage, dermatitis, eczema, etc., and even death in se...
