Tree insect prevention and antifreeze paint and preparing method

Abstract

The invention discloses a tree insect prevention and antifreeze paint and a preparing method. The paint is prepared from talcum powder, micropore calcium carbonate, high viscosity attapulgite clay, polyurethane, graphene, pyrethrum, radix rehmanniae, cinnamon, golden larch bark, radix euphorbiae lantu, thunder godvine and acorus calamus. The preparing method comprises the steps that traditional Chinese medicine components are weighed and smashed, and then are placed into a Soxhlet extractor to be extracted, and an obtained extracting solution is concentrated and prepared into lyophilized powder; a polyurethane aqueous solution is added into a reaction kettle, a graphene aqueous solution is added, and a stirring reaction is conducted for 0.5-1.5 h; the talcum powder, micropore calcium carbonate and the high viscosity attapulgite clay are added, and are placed into a shearing machine to be sheared after being evenly mixed and stirred, and then the lyophilized powder is added into the mixture for ultrasonic treatment for 20-30 min, so that the paint is obtained. The tree insect prevention and antifreeze paint has a good insect prevention and sterilization effect, is long in pesticide effect, further has a good heat preservation effect, and has high application value and a good prospect.

Description

technical field [0001] The invention relates to the technical field of tree outer layer coatings, in particular to a tree insect-proof and antifreeze coating and a preparation method. Background technique [0002] With the acceleration of urban modernization, the proportion of reinforced concrete structures in our cities is increasing, and the urban "heat island effect" is becoming more and more serious. In order to make the city develop healthily, urban landscaping has attracted more and more attention. Trees occupy a large proportion of landscaping. [0003] Trees are indispensable plants in people's lives. They can not only decorate and beautify the city, but also purify the city's air, absorb dust, and reduce the number of bacteria in the air. Therefore, the garden department will agree to plan urban vegetation greening. When the temperature drops, in order to ensure that the trees can survive the winter normally and prevent the invasion of diseases and insect pests, pe...

[0004] The Chinese invention patent application with the publication number CN101760105A discloses an environment-friendly insect-proof and heat-insulating paint for trees. Compared with the prior art, the environment-friendly wood insect-proof and heat-preserve paint consists of talcum powder, calcium carbonate, sodium hexametaphosphate, light calcium powder, It is prepared from ethylene glycol, acrylic emulsion, imidacloprid, anti-aging agent and antifreeze agent, and then add night reflective powder into the formula to form a reflective effect under the light. effect, but the heat preservation effect is not obvious, and the ethylene glycol in the component is toxic to humans and animals, so it is not safe to use
