Preparation method of multifunctional street tree whitening paint

Abstract

The invention relates to a preparation method of a multifunctional street tree whitening paint, and belongs to the field of preparation of whitening paints. The preparation method comprises the following steps: leaching pomegranate barks by using ethanol, concentrating to prepare bacteriostatic solution, and then performing high-temperature calcination to prepare a nano titanium oxide photo-catalytic material; and adding the bacteriostatic solution and the photo-catalytic material into a self-made paint substrate, adding an appropriate amount of fluorescent powder, performing dispersive stirring by using a high-speed dispersion machine, and barreling and sealing to obtain the multifunctional street tree whitening paint. The paint integrates multiple functions of insect prevention, heat preservation, freezing resistance, catalytic degradation of automobile exhaust gas, night indication and the like, and is pollution-free to environment. Compared with the prior art, the multifunctional street tree whitening paint provided by the invention cannot corrode barks, is long in insect prevention time effect, and cannot lose effectiveness due to irradiation of sunlight and flushing of rainwater.

Description

technical field [0001] The invention relates to a preparation method of a multifunctional whitening paint for street trees, and belongs to the field of whitening paint preparation. Background technique [0002] Most of the current gardens, orchards, street trees, landscaping and other trees need outer coatings. On the one hand, these outer coatings are for insect protection and heat preservation, and on the other hand, they are also for beautifying the environment. Therefore, the outer coatings of these trees are generally required to be insect-proof. , thermal insulation, strong ornamental, not easy to come off and so on, but the anti-insect paint for trees in the prior art generally adopts lime water three-in-one to brush, and its anti-insect effect is poor and easy to come off, which can not meet the requirements of reality. [0003] Street trees refer to the tree species that are planted on both sides of the road and at the detachment belt to shade vehicles and pedestria...

AI Technical Summary

Problems solved by technology

[0004] The main technical problem to be solved by the present invention is to provide a multi-functional white paint for street trees in view of the defects that the current white paint for street trees generally uses lime water three-in-one for brushing, which has poor insect-proof effect and is easy to fall off, and the whitening paint has a single function. The preparation method is that the antibacterial solution is obtained by extracting pomegranate peel with ethanol and concentrating it, and then calcining at a high temperature to obtain a nano-titanium oxide photocatalytic material, adding the antibacterial solution and photocatalytic material to the self-made paint base solution, adding Appropriate amount of fluorescent powder, disperse and stir with a high-speed disperser, seal it in a barrel, and then get a multi-functional street tree brush white paint
