Abstract

The invention belongs to the field of building materials, and in particular relates to a rat-proof coating and a preparation method thereof. The rat-proof coating is mainly prepared from the followingraw materials in parts by weight: ludisia discolor herb, lycoris aurea, vaccinium bracteatum, diospyros lotus fruit powder, euonymus, Ilex cornuta fruits, tannin extract, nano titanium dioxide, meliaazedarach fruits, calcium lignosulfonate, thermoplastic polyurethane and zinc stearate. According to the rat-proof coating provided by the invention, the melia azedarach fruits, the diospyros lotus fruit powder, the vaccinium bracteatum, the lycoris aurea, the ludisia discolor herb and the Ilex cornuta fruits which have special smell are added, so that the smell tolerance of rats to the coating is low; the calcium lignosulfonate, the thermoplastic polyurethane and the zinc stearate are added, so that the coating has excellent weather resistance, and is suitable for long-term use outdoors; andthe rat-proof coating has no toxicity or harm to the human body and the environment, and no damage to a substrate, and is also suitable for use in doors.

Description

【Technical field】 [0001] The invention belongs to the field of building materials, and in particular relates to a rodent-proof coating and a preparation method thereof. 【Background technique】 [0002] Rats are voracious animals, and each rat eats food equivalent to one-tenth of its body weight every day. The mouse is called a mouse in the north, and it really lives up to its name. It is estimated that about 5% of the grain produced every year is taken away by rats, and 50 million tons of grain is lost every year in the world, resulting in a loss of hundreds of millions of dollars. In addition, mice can also steal the seeds of the forest, gnaw on the seedlings and bark, and bring serious harm to the forest. Rats can destroy grasslands, compete with livestock for pasture, and affect animal husbandry. The harm of rats to industry and construction is also very serious, and the accidents caused by short circuit caused by rats biting through electric wires are not uncommon, and...
