Special mouldproof mothproof coating for metro

Abstract

The invention discloses a special mouldproof-mothproof coating for metro and a preparation method thereof. The prepared coating consists of 96 percent of ordinary coatings and 4 percent of mouldproof-mothproof agents according to mass percent, wherein the mouldproof-mothproof agents consist of the following raw materials according to mass percent: 18 percent to 25 percent of radix stemonae, 5 percent to 8 percent of hellebore, 13 percent to 18 percent of mustard, 13 percent to 18 percent of sophora alopecuroide, 33 percent to 35 percent of bovine bone meal and 8 percent to 12 percent of pubescent holly root. The method comprises the following steps: pulverizing and mixing the radix stemonae, the hellebore, the mustard, sophora alopecuroide and the pubescent holly root, carrying out reflux extraction through ethanol for 5 hours, and concentrating, drying and grinding extractive; mixing the ground extractive with the bovine bone meal, uniformly mixing to obtain the mouldproof-mothproof agent; and mixing the ordinary coatings with the mouldproof-mothproof agent at normal pressure and temperature, continuously agitating within the range of the pH value ranging from 5.5 to 8.5 to achieve uniform mixing, thereby obtaining the finished coating. The coating has good mouldproof and mothproof effects, and has considerably good function of environmental protection.

Description

Technical field [0001] The invention belongs to the environmental protection technical field of energy and chemical industry, and specifically relates to a special anti-mildew and insect-proof paint for subways, which can effectively prevent mold and insects and is suitable for the subway environment, and the naturalness of its raw materials can be very friendly to the environment. polluted environment. Background technique [0002] The subway, as a product of the highly developed human knowledge and civilization, has excellently solved the problem of high population density that is common in the world at this stage and it is difficult to circulate quickly. In terms of space, the distance between people, regions and regions is shortened, and the purpose of rapid population circulation is achieved; in terms of time, it greatly saves people's time for transportation, which greatly facilitates the communication and development of modern humans. However, the high population density,...

Problems solved by technology

[0004] At present, the existing anti-mildew or insect-proof coatings and their processing methods all add anti-mildew and insect-proof ingredients to the paint, but these anti-mildew and insect-proof ingredients have some defects, such as not suitable for the hot and humid environment in the subway, residual toxicity, easy to It can make the killed object resistant to drugs and is expensive, and cannot be used as an effective component of an effective anti-mildew and anti-insect coating
