Technical Field

The invention belongs to the field of production of glass water, and particularly relates to biomass glass water for paint surfaces and a preparation method thereof.

Background

The glass water is cleaning liquid for the automobile windshield, and is sprayed on the windshield and then used for scraping and sweeping the surface of the glass back and forth through the windscreen wiper, so that the glass water plays a role in removing dirt, oil stains, gum, insect corpses and other stains and ensuring clear driving vision. Therefore, the glass water is a consumable product and has high use frequency. But the glass water on the market at present has limited cleaning capacity; some cleaning agents have strong cleaning capability but are not environment-friendly enough, and the contained components have larger irritation; the existing glass water cannot resist low temperature and can block the glass water spray head; some glass water erodes substrates such as windshields; glass water cannot be used for cleaning vehicle body finishes for a long time, and the like.

The invasive plants have bad influence on the ecological environment, people make various uses of the invasive plants, but reports of applying the invasive plants to the glass water are not available, and if the invasive plants can be applied in a large range, the wastes can be changed into valuables, and the ecological balance is greatly improved.

Therefore, the development of the glass water which takes biological materials, particularly invasive plants, as main components, can resist certain low temperature, can melt snow and frost, has the functions of protecting windshields and most smooth substrate surfaces and can be used for cleaning the whole body of an automobile for a long time, greatly expands the variety and application range of the glass water and has wide market prospect.

The invention has the beneficial effects that:

(1) the paint surface of the invention can use the biomass glass water as the environment-friendly biomass raw material, particularly biomass protective components from invasive plants, has no damage to base materials such as windshield glass, paint surface of a vehicle body and the like, but has the effects of protecting and preventing abrasion, thereby not only reducing the cost and realizing the change of waste into valuable, but also further improving the safety and functionality of the glass water and improving the ecological balance. The paint surface can be prepared from biomass glass water, and the efficient cleaning function is achieved mainly through the compounding of a bio-based surfactant, a biomass cosolvent, a friction agent and a non-deionized water solvent: one end of the bio-based surfactant molecule is hydrophilic, and the other end is hydrophobic, so that stains such as dust, oil stains and the like can be emulsified into small micro-droplets which are peeled and surrounded, and the stains can be conveniently removed; the biomass cosolvent strengthens the penetrating and decomposing effects of the bio-based surfactant on stains; the solvent of the non-deionized water dissolves various stubborn stains such as gum, insect corpses and the like by the principle of similar intermiscibility; the abrasive provides sufficient abrasive mechanical effect while ensuring no damage to the substrate. Experiments prove that the reasonable compounding effect of the four components is far better than that of any one of the four components which are independently used, which shows that the four components have a synergistic effect.

(2) The paint surface can be made of biomass glass water, and the low temperature resistance, snow melting and frost prevention functions of the paint surface are the comprehensive synergistic effects of a non-deionized water solvent, a biomass protective component and an antistatic agent: the non-deionized water solvent gives a sufficiently low freezing point and can fully melt snow; the biomass protective component can form a protective film on the surface of base materials such as windshield and the like, so that solid can not be precipitated below zero, and the anti-freezing effect is enhanced; the antistatic agent ensures the smooth spraying of the glass water and can also form a protective film to prevent frost and the like. The four components ensure that the glass water can be normally used in a lower temperature environment. The paint surface of the invention can use the biomass glass water, the addition of the antistatic agent, the dipropylene glycol monoethyl ether and the friction agent surprisingly endows the glass water with the anti-staining effect on substrates such as windshields and the like, the addition sequence of the dipropylene glycol monoethyl ether during the preparation also has an influence on the effect, and the glass water can obtain relatively ideal anti-staining effect and better dispersion stability only by finally adding the dipropylene glycol monoethyl ether.

(3) The paint surface of the invention can use biomass glass water, has extremely wide adaptability to base materials, can be suitable for the inner and outer side surfaces of various base materials such as windshields, all paint surfaces of car bodies, hub metal, resin lenses, acrylic furniture and the like, has a low freezing point which can reach-20 ℃, can be used in four seasons, and can be used for cleaning the whole bodies of cars for a long time.

In conclusion, the paint surface can use the biomass glass water as the environment-friendly biomass raw material, particularly the biomass protective component from invasive plants, has no damage to the base materials such as windshield glass, paint surface of a vehicle body and the like, but has the effects of protecting and preventing abrasion, thereby not only reducing the cost and changing waste into valuable, but also further improving the safety and functionality of the glass water and improving the ecological balance.

The paint surface can be prepared from biomass glass water, and the efficient cleaning function is achieved mainly through the compounding of a bio-based surfactant, a biomass cosolvent, a friction agent and a non-deionized water solvent: one end of the bio-based surfactant molecule is hydrophilic, and the other end is hydrophobic, so that stains such as dust, oil stains and the like can be emulsified into small micro-droplets which are peeled and surrounded, and the stains can be conveniently removed; the biomass cosolvent strengthens the penetrating and decomposing effects of the bio-based surfactant on stains; the solvent of the non-deionized water dissolves various stubborn stains such as gum, insect corpses and the like by the principle of similar intermiscibility; the abrasive provides sufficient abrasive mechanical effect while ensuring no damage to the substrate. Experiments prove that the reasonable compounding effect of the four components is far better than that of any one of the four components which are independently used, which shows that the four components have a synergistic effect.

The paint surface can be made of biomass glass water, and the low temperature resistance, snow melting and frost prevention functions of the paint surface are the comprehensive synergistic effects of a non-deionized water solvent, a biomass protective component and an antistatic agent: the non-deionized water solvent gives a sufficiently low freezing point and can fully melt snow; the biomass protective component can form a protective film on the surface of base materials such as windshield and the like, so that solid can not be precipitated below zero, and the anti-freezing effect is enhanced; the antistatic agent ensures the smooth spraying of the glass water and can also form a protective film to prevent frost and the like. The four components ensure that the glass water can be normally used in a lower temperature environment.

The paint surface of the invention can use the biomass glass water, the addition of the antistatic agent, the dipropylene glycol monoethyl ether and the friction agent surprisingly endows the glass water with the anti-staining effect on substrates such as windshields and the like, the addition sequence of the dipropylene glycol monoethyl ether during the preparation also has an influence on the effect, and the glass water can obtain relatively ideal anti-staining effect and better dispersion stability only by finally adding the dipropylene glycol monoethyl ether.

The paint surface of the invention can use biomass glass water, has extremely wide adaptability to base materials, can be suitable for the inner and outer side surfaces of various base materials such as windshields, all paint surfaces of car bodies, hub metal, resin lenses, acrylic furniture and the like, has a low freezing point which can reach-20 ℃, can be used in four seasons, and can be used for cleaning the whole bodies of cars for a long time.
