Description
Technical Field
The invention relates to the technical field of cleaning products, in particular to a degumming composition and a preparation method and application thereof.
Background
With the wider application of adhesives in China, a large amount of residual adhesives are generated, and the residual adhesives are required to be removed in factories, equipment, families, shops, furniture, automobiles and public places, such as advertisements, labels, adhesive stickers, home decoration and the like.
The main methods for removing the waste rubber at home and abroad comprise a solvent method, an emulsion method, high-pressure water equipment cleaning, dry ice equipment cleaning and mechanical scrubbing. Most of raw materials used in the cleaning by the solvent and emulsion method are non-environment-friendly solvents such as tetrachloroethylene, ethyl acetate and the like, all of the solvents belong to toxic solvents, and the solvents can cause liver damage by human body inhalation, can cause dermatitis, eczema and the like, can even cause death of serious patients and can cause serious harm to the environment. Although the cleaning method of the high-pressure water and the dry ice is safe and environment-friendly, the glue scale can be thoroughly and rapidly removed, the initial investment of the equipment is large, and the method is not suitable for popularization and application. The portable cleaning machine has the problem of incomplete cleaning.
Therefore, it is a trend in the future to develop a glue removing composition which not only has an excellent glue removing effect, but also is more important to be safe, environment-friendly and efficient, and has excellent comprehensive properties.

The second aspect of the invention provides a preparation method of the glue removing composition, which comprises the following steps: firstly, adding limonene and a cosolvent into a stirring kettle for stirring; then adding the rest raw materials, continuously stirring until the raw materials are dissolved, standing and defoaming for 8-12 hours; and finally, filtering and packaging to obtain the product.
The third aspect of the invention provides application of the degumming composition, and the degumming composition can be applied to aerosol and degumming liquid.
Has the advantages that: the invention provides a degumming composition which is prepared from raw materials such as limonene, dealkylated solvent oil, dibasic acid ester, cosolvent, unsaturated acid ester and the like. The degumming composition is safe and environment-friendly, has soft and fragrant taste, short degumming time and high degumming rate, and can completely remove the gum. Meanwhile, the inventors have unexpectedly found that the addition of a proper amount of polyether derivative having amino group to the raw materials can improve the thermal stability of the degumming composition. The degumming composition can ensure that the degumming efficiency is excellent within at least 3 months at the temperature of 50 ℃, and the taste is fragrant and mild without pungent taste.
Detailed Description
The disclosure may be understood more readily by reference to the following detailed description of preferred embodiments of the invention and the examples included therein. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. In case of conflict, the present specification, including definitions, will control.
The term "prepared from …" as used herein is synonymous with "comprising". The terms "comprises," "comprising," "includes," "including," "has," "having," "contains," "containing," or any other variation thereof, as used herein, are intended to cover a non-exclusive inclusion. For example, a composition, process, method, article, or apparatus that comprises a list of elements is not necessarily limited to only those elements but may include other elements not expressly listed or inherent to such composition, process, method, article, or apparatus.
When an amount, concentration, or other value or parameter is expressed as a range, preferred range, or as a range of upper preferable values and lower preferable values, this is to be understood as specifically disclosing all ranges formed from any pair of any upper range limit or preferred value and any lower range limit or preferred value, regardless of whether ranges are separately disclosed. For example, when a range of "1 to 5" is disclosed, the described range should be interpreted to include the ranges "1 to 4", "1 to 3", "1 to 2 and 4 to 5", "1 to 3 and 5", and the like. When a range of values is described herein, unless otherwise stated, the range is intended to include the endpoints thereof and all integers and fractions within the range.
The singular forms "a", "an" and "the" include plural referents unless the context clearly dictates otherwise. "optional" or "any" means that the subsequently described event or events may or may not occur, and that the description includes instances where the event occurs and instances where it does not.
Approximating language, as used herein throughout the specification and claims, is intended to modify a quantity, such that the invention is not limited to the specific quantity, but includes portions that are literally received for modification without substantial change in the basic function to which the invention is related. Accordingly, the use of "about" to modify a numerical value means that the invention is not limited to the precise value. In some instances, the approximating language may correspond to the precision of an instrument for measuring the value. In the present description and claims, range limitations may be combined and/or interchanged, including all sub-ranges contained therein if not otherwise stated.
In addition, the indefinite articles "a" and "an" preceding an element or component of the invention are not intended to limit the number requirement (i.e., the number of occurrences) of the element or component.

In order to solve the technical problems, the first aspect of the invention provides a glue removing composition, which at least comprises the following components in parts by weight: 50-70 parts of limonene, 45-80 parts of unsaturated acid ester, 35-50 parts of dealkylated solvent oil, 5-15 parts of dibasic acid ester and 10-20 parts of cosolvent.
Preferably, the glue removing composition at least comprises the following components in parts by weight: 60 parts of limonene, 72 parts of unsaturated acid ester, 45 parts of dealkylated solvent oil, 10 parts of dibasic acid ester and 15 parts of cosolvent.
Limonene
In the invention, the limonene is D-limonene.
The CAS number of the D-limonene is 5989-27-5.
Unsaturated acid ester
In the present invention, the unsaturated acid ester is at least one selected from the group consisting of methyl oleate, ethyl oleate, methyl 10-undecenoate, methyl tridecenoate, 3-methylbutyl undec-10-enoate, ethyl 5-methyl-2, 4-hexadienoate, (9Z) -9-octadecenoic acid propyl ester, methyl 2-nonenoate, and methyl cis-7-hexadecenoic acid.
Preferably, the unsaturated acid ester is methyl oleate.
The CAS number of the methyl oleate is 112-62-9.
In the invention, the mass ratio of the limonene to the unsaturated acid ester is 1: (1-1.4).
Preferably, the mass ratio of the limonene to the unsaturated acid ester is 1: 1.2.
in the degumming composition provided by the invention, limonene which is one of main components is a pure natural extract, is safe and environment-friendly, has aromatic smell, is beneficial to removing surface stains, and is also an excellent solvent when being used for degumming. However, the removal effect on the cured paste is not significant, and particularly the removal effect on the cured epoxy resin is poor. The inventor finds out through experiments that the addition of a certain amount of unsaturated acid ester monomers into the raw materials of the glue removing composition can increase the removing effect of limonene on cured glue. Especially, when the length of the chain of the acid segment with double bonds in the selected unsaturated acid ester monomers is significantly longer than that of the chain of the alcohol segment, the removal rate of the cured epoxy resin colloid can achieve a very good effect. The inventors speculate that the possible reasons are: when the unsaturated acid ester monomer is compounded with the limonene, the unsaturated acid ester is very soft and does not have any branched chain, and in a system of the glue removing composition, the monomer contains a certain amount of unsaturated double bonds, and the compounding with the limonene is favorable for improving the flowability and the dispersing capacity of the limonene. When the degumming composition is used for degumming, the addition of the unsaturated acid ester is beneficial to generating a certain constraint effect on the limonene and preventing the limonene from volatilizing. The limonene permeates into a layer of the rubber surface to melt and burst the high-molecular rubber material, and the ester group structure is positioned on one side of the unsaturated acid ester monomer close to the head, so that the acting force between the swollen cured rubber body and the carrier is favorably reduced. Meanwhile, the unsaturated acid ester monomer has a very long structure and can be adsorbed on the waste glue surface, so that the removed waste glue surface is relatively complete and cannot be broken, and the easy and complete removal of the waste glue is facilitated.
Hydrocarbon-removed solvent oil
In the invention, the density of the dealkylated solvent oil is 0.766-0.827g/cm3。
Preferably, the density of the de-hydrocarbon solvent oil is 0.808g/cm3。
In the invention, the initial distillation temperature of the distillation range of the hydrocarbon-removed solvent oil is 142-279 ℃.
Preferably, the initial distillation temperature of the distillation range of the hydrocarbon-removed solvent oil is 248 ℃.
In the present invention, the dealkylation solvent oil is a hydrocarbon solvent oil, and is not particularly limited, and may be at least one selected from the group consisting of dearomatization solvent Exxsol series products D30, D40, D80, D110, and D130 from shanghai coma chemical company, ltd.
Most preferably, the hydrocarbon-removed solvent oil is selected from environmental-friendly solvent oil D110 of Shanghai Huishusan chemical Co.
The inventor finds that the addition of the unsaturated acid ester monomer can well improve the removal rate of the glue, but the glue removal time is long and the working efficiency is low. The inventor finds that after a certain amount of high-boiling-point dealkylation solvent oil is added into a system of the degumming composition, the degumming time of the rubber can be obviously prolonged, the excellent synergistic effect can be exerted between the high-boiling-point dealkylation solvent oil and limonene and unsaturated acid ester monomers in the degumming process, the degumming effect of the degumming composition on various kinds of rubber can be obviously improved, and the degumming time can be greatly shortened. The inventors consider that possible reasons are: adding proper amount of the mixture with the density of 0.766-0.827g/cm3The high boiling point dealkylation solvent oil with the distillation range initial distillation temperature of 142-279 ℃ can obviously improve the fluidity of the limonene and the unsaturated acid ester monomer in the system. As the initial distillation temperature of the dealkylated solvent oil is higher, a certain stabilizing effect is generated on the system, enough power is provided for the flexible unsaturated acid ester monomer and the limonene in the degumming process for a long time, the effect of rapid permeation of the system is enhanced, and the degumming time is greatly shortened.
Dibasic acid ester
In the invention, the dibasic acid ester is dibasic acid methyl ester monomer.
Preferably, the dibasic acid methyl ester monomer is dibasic acid methyl ester of C5-C10.
Preferably, the dibasic acid methyl ester of C5-C12 is at least one selected from dimethyl succinate, dimethyl glutarate, dimethyl adipate, dimethyl malonate, dimethyl alpha-ketoglutarate, dimethyl malonate, dimethyl suberate, dimethyl 4-oxopimelate, dimethyl sebacate and dimethyl 3-methylglutarate.
More preferably, the dibasic acid methyl ester monomer is selected from the group consisting of dimethyl succinate, dimethyl glutarate and dimethyl adipate.
Most preferably, the mass ratio of the dimethyl succinate to the dimethyl glutarate to the dimethyl adipate is 1: 1.5: 0.5.
cosolvent
In the invention, the cosolvent is at least one selected from ethylene glycol ethyl ether, ethylene glycol butyl ether, diethylene glycol butyl ether, propylene glycol methyl ether and dipropylene glycol butyl ether.
Polyether derivative having amino group
In the invention, the degumming composition also comprises polyether derivatives with amino groups.
Preferably, the weight ratio of the unsaturated acid ester to the polyether derivative having an amino group is 1: (0.05-0.2).
More preferably, the weight ratio of the unsaturated acid ester to the polyether derivative having an amino group is 1: 0.12.
most preferably, the polyether derivative having an amino group is 4-aminobutyraldehyde diethyl acetal.
The CAS number of the 4-aminobutyraldehyde diethyl acetal is 6346-09-4.
The inventor surprisingly found that the addition of a proper amount of polyether derivative with amino groups enables the glue removing rate of the glue removing composition to be further improved, and the glue removing time to be further shortened. The inventors consider that possible reasons are: the addition of a proper amount of polyether derivative with amino can improve the thermal stability of the degumming agent, and ensure that the degumming composition still has excellent degumming efficiency and fragrant and mild taste without pungent smell after the degumming agent is kept for 3 months at 50 ℃.
The second aspect of the invention provides a preparation method of the glue removing composition, which comprises the following steps: firstly, adding limonene and a cosolvent into a stirring kettle for stirring; then adding the rest raw materials, continuously stirring until the raw materials are dissolved, standing and defoaming for 8-12 hours; and finally, filtering and packaging to obtain the product.
