Description
Technical Field
The invention belongs to the technical field of cleaning agents, and particularly relates to a phase-change down jacket dry cleaning agent and a preparation method thereof.
Background
With the acceleration of modern life rhythm, people are increasingly reluctant to put time into daily housework, but hope that more efficient products appear to save the time required by the housework, so that some convenient and efficient cleaning products can be produced, and the down jacket dry cleaning agent is one of the more widely applied cleaning products.
The prior dry cleaning agent for down jackets takes a surfactant with strong permeability as a main component, and assists in removing dirt by friction of a wet towel, but sometimes has poor effect, can only fade dirt or enlarge a dirt ring, and remains residues, so that the dirt cannot be removed fundamentally; some of the down jackets use an oily solvent to play a similar and compatible role, and are supplemented with a powder adsorbent to transfer oil stains to the adsorbent, so that stains on the down jackets are taken away, but powder residues are easy to remain and are embedded in gaps on the surface layers of the down jackets, secondary pollution is brought, and the used solvent has high toxicity and is not friendly to the environment.
Inspired by phase-change materials, if a down jacket dry cleaning agent which is dried and then changes phase into a complete solid adhesive film without powder residue and friction can be developed, the defects of the prior art can be overcome, so that the application of the down jacket dry cleaning agent is more competitive and popular.
Disclosure of Invention
This section is for the purpose of summarizing some aspects of embodiments of the invention and to briefly introduce some preferred embodiments. In this section, as well as in the abstract and the title of the invention of this application, simplifications or omissions may be made to avoid obscuring the purpose of the section, the abstract and the title, and such simplifications or omissions are not intended to limit the scope of the invention.
The present invention has been made in view of the above-mentioned technical drawbacks.
Therefore, as one aspect of the invention, the invention overcomes the defects in the prior art and provides a phase-change down jacket dry cleaning agent and a preparation method thereof.
In order to solve the technical problems, the invention provides the following technical scheme: a phase-change dry cleaning agent for down jackets is characterized in that: the composite material comprises, by weight, 1.5-3.5 parts of dimethyl silicone oil, 4-8.5 parts of silica gel, 2.5-5 parts of a biomass surfactant, 57-80 parts of a first solvent and 16.5-27 parts of a second solvent.
As a preferable scheme of the phase-change down jacket dry cleaning agent, the phase-change down jacket dry cleaning agent comprises the following components: the silica gel comprises one or more of plastic soft silica gel, amorphous silica gel and gas phase nano silicon dioxide.

As a preferable scheme of the phase-change down jacket dry cleaning agent, the phase-change down jacket dry cleaning agent comprises the following components: the first solvent comprises one or more of lipophilic solvent and ethanol.
As a preferable scheme of the phase-change down jacket dry cleaning agent, the phase-change down jacket dry cleaning agent comprises the following components: the second solvent is a sodium percarbonate aqueous solution with the mass fraction of 3%.
As a preferable scheme of the phase-change down jacket dry cleaning agent, the phase-change down jacket dry cleaning agent comprises the following components: the lipophilic solvent is one or more of sweet orange oil, oleum Terebinthinae, oleum Eucalypti, and pericarpium Citri Tangerinae essential oil.
In one aspect of the present invention, the present invention overcomes the disadvantages in the prior art, and provides a method for preparing a phase-change dry cleaning agent for down jackets, which comprises: slowly adding the dimethyl silicone oil into the first solvent, and stirring and mixing to obtain a mixed solution A; slowly adding silica gel and a biomass surfactant into a second solvent, and stirring and mixing to obtain a mixed solution B; and mixing and homogenizing the mixed solution A, B to obtain the phase-change down jacket dry cleaning agent.
As a preferable scheme of the preparation method of the phase-change down jacket dry cleaning agent, the phase-change down jacket dry cleaning agent comprises the following steps: the stirring and mixing are carried out at 450-510 rpm for 5-10 min.
As a preferable scheme of the preparation method of the phase-change down jacket dry cleaning agent, the phase-change down jacket dry cleaning agent comprises the following steps: the homogenizing is carried out at the rotating speed of 6800-7200 rpm for 3-7 min.
As a preferable scheme of the preparation method of the phase-change down jacket dry cleaning agent, the phase-change down jacket dry cleaning agent comprises the following steps: mixing the mixture A, B is to slowly add mixture B to mixture a.
The invention has the beneficial effects that:
1. the phase-change down jacket dry cleaning agent disclosed by the invention adopts environment-friendly raw materials, is different from the traditional solvent type dry cleaning agent, mainly adopts a water-based solvent, and is matched with a surfactant which is easy to biodegrade, a phase-change material which does not produce powder and the like, so that the dry cleaning agent has the characteristic of environmental friendliness.
2. The phase-change down jacket dry cleaning agent disclosed by the invention achieves the effects of quickly penetrating and decomposing stains mainly by compounding three components, namely dimethyl silicone oil, a sodium percarbonate solution and a biomass surfactant. The lipophilic property of the dimethyl silicone oil assists the biomass surfactant to quickly permeate through the surface layer of the down jacket, simultaneously, the oily stains are dissolved, and the spontaneous foaming and oxidative decomposition effects of the sodium percarbonate solution are added to further break and disintegrate the stains, so that the thorough removal of the stains on the surface layer of the down jacket and the inner stains close to the outer layer can be realized without mechanical friction.
3. The phase-change dry cleaning agent for down coats is divided into a mixed solution A and a mixed solution B in the preparation process, the mixed solution A and the mixed solution B are slowly added into the mixed solution A, and the solvent components in A, B cannot be exchanged. Experiments prove that only by the preparation method and the feeding sequence, the obtained down jacket dry cleaning agent has better uniformity and effect stability, which also indicates that the strict preparation method and the feeding sequence in the preparation process can ensure that the sequential reaction among the components can be smoothly carried out, thereby ensuring the final effect of the down jacket dry cleaning agent.
